Vanilla Java on Windows to connect with DB2 on z/OS - java

I am trying to use simple java (minus any framework like Spring or containers like Tomcat etc) to connect to DB2 on mainframe. Here are the steps I took.
Added the db2 drivers to my local maven repository.
mvn install:install-file -Dfile=db2jcc_license_cisuz.jar -DgroupId=com.ibm.db2 -DartifactId=db2jcc -Dversion=1.0 -Dpackaging=jar
mvn install:install-file -Dfile=db2jcc4.jar -DgroupId=com.ibm.db2 -DartifactId=db2jcc4 -Dversion=1.0 -Dpackaging=jar
Created a simple java project using maven archetype. Added the following to the pom.xml
<!-- Connect to DB2 on Mainframe. -->
<dependency>
<groupId>com.ibm.db2</groupId>
<artifactId>db2jcc </artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.ibm.db2</groupId>
<artifactId>db2jcc4 </artifactId>
<version>1.0</version>
</dependency>
Now created a simple Junit and added the following
Driver driver = (Driver) Class.forName("com.ibm.db2.jcc.DB2Driver")
.newInstance();
DriverManager.registerDriver(driver);
Connection connection = DriverManager.getConnection(
"jdbc:db2://server:port/dbname", "username",
"password");
This does not work. It tells me
com.ibm.db2.jcc.am.SqlInvalidAuthorizationSpecException: [jcc][t4][2010][11246][4.13.80] Connection authorization failure occurred. Reason: Local security service non-retryable error. ERRORCODE=-4214, SQLSTATE=28000
I tried changing the driver type as well.
Class.forName("COM.ibm.db2os390.sqlj.jdbc.DB2SQLJDriver");
But did not work. Still same problem.
I am working off a Windows machine and I have made no configuration for connecting to DB2 at all.
However, from the same Windows machine, using IBM Datastudio, and using the same credentials, I am able to connect to the database and run queries.
The stacktrace
com.ibm.db2.jcc.am.SqlInvalidAuthorizationSpecException: [jcc][t4][2010][11246][3.62.80] Connection authorization failure occurred. Reason: Local security service non-retryable error. ERRORCODE=-4214, SQLSTATE=28000

Please help.

Managed to get this to work. A few things that were wrong with my original attempt.
Both db2jcc_license_cisuz-1.0.jar and db2jcc4-V97FP5.jar are required in the class path. Putting them in your local maven repository and adding them in the pom.xml is fine. However, both of them have to be there. This is how my pom.xml looks now. You could add them both in the classpath by any other method.
<dependency>
<groupId>com.ibm.db2</groupId>
<artifactId>db2jcc_license</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.ibm.db2</groupId>
<artifactId>db2jcc4</artifactId>
<version>1.0</version>
</dependency>
This driver works fine.
Class.forName("com.ibm.db2.jcc.DB2Driver");
Connection connection1 = DriverManager
.getConnection(
Finally, something that took embarassingly long amount of time for me to figure out. Since we are talking about connection to DB2 on z/OS it might have some additional restrictions of password (those which might not apply to your regular dev environment of windows / linux), that are easy to forget.
Take care of these things and you should be all set. Thanks.

It's my first time to work on setting everything up from grounds. I'm not sure if it's pom dependency issue, singleton webdriver issue, or something else. Could anyone share an eyesight on this and give some clues? Much appreciated.
This error message...
java.lang.AbstractMethodError: org.openqa.selenium.remote.service.DriverService$Builder.createArgs()Lcom/google/common/collect/ImmutableList;
...implies that there is some incompatibility between the version of the binaries you are using specifically with the guava dependency.
You are using chrome= 76.0
You are using the following:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-chrome-driver</artifactId>
<version>3.5.3</version>
<scope>test</scope>
</dependency>
Your Selenium Client version is 3.5.3 which is more then 2 years older.
Your JDK version is unknown to us.
So there is a clear mismatch between the Selenium Client v3.5.3 and Chrome Browser v76.0
However as per the discussions in:
java.lang.NoSuchMethodError: com.google.common.collect.ImmutableList.builderWithExpectedSize
NoSuchMethodError: com.google.common.collect.ImmutableList.toImmutableList()Ljava/util/stream/Collector; after upgrade to 2.0.16
These issues crop up due to incompatibile Guava dependency.
The current guava version used within selenium-java-3.141.59 is guava-25.0-jre
Solution
Ensure that:
JDK is upgraded to current levels JDK 8u222.
Selenium is upgraded to current levels Version 3.141.59.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
Update
So presumably your main question with respect to the error:
java.lang.AbstractMethodError: org.openqa.selenium.remote.service.DriverService$Builder.createArgs()Lcom/google/common/collect/ImmutableList;
is solved. Congratulations.
Now, as per your question update as you are seeing the error:
java.lang.NoClassDefFoundError: org/apache/http/auth/Credentials
There are two aspects.
NoClassDefFoundError: NoClassDefFoundError in Java occurs when Java Virtual Machine is not able to find a particular class at runtime which was available at compile time. You can find a detailed discussion in Exception in thread “main” java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver
http/auth: Traces of http/auth implies http client is still in use where as the CHANGELOG reflects:
The HttpClient implementation details were out of HttpCommandExecutor right from Selenium v2.45.0.
With the availability of Selenium v3.11, Selenium Grid was switched to use OkHttp rather than the Apache HttpClient.
Further with the release of Selenium v3.141.0, Apache HttpClient was removed from selenium-server-standalone which drastically
reduced the size of selenium server distribution package.
Even the apache-backed httpclient was also removed.
You can find a detailed discussion in org.openqa.selenium.remote.internal.ApacheHttpClient is deprecated in selenium 3.14.0 - What should be used instead?
Remove scope from your POM.
test
or main
Isn't needed for your tests to run
used this gauva jar with latest testng 7.3. Resolved this error also dont configure any testNG seperately. Please remove configuration if we add it in pom.xml
I was facing the same issue. The following steps helped resolve it:
Go to your POM file and comment out/ remove the following dependency:
--> org.seleniumhq.selenium
--> selenium-java
--> 2.48.2
Check what version you have.
Then copy the latest mvn dependency which is 4.1.1 as of now
Perform mvn clean install (till this point it will be sufficient)
Perform reload all maven projects
Perform download sources
Build your project again
Play/ perform mvn clean install again
FYI: as per my knowledge, this issue occurs at compile time when you execute the code. Or the time when you execute a code in a new project which was compiled with different dependencies and versions earlier.

Please help me figure out what's wrong here.
I suppose you forget to include hadoop-aws package to your project. This package will allow you to work with s3:// schema
<!-- https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-aws -->
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-aws</artifactId>
<version>2.6.0</version>
</dependency>
Since you are trying to execute this code on your local system, your code won't know how to access s3 file system.
You can do one of the two things to solve this problem:
Configure AWS credentials in your system so that your code will somehow try to reach s3 bucket. I will not recommend this approach for various reasons.
Keep your file path in configuration file. Use 2 configuration files - one for testing code and other for production environment. In test environment, use paths like c:\path\to\your\dummy\folder\ and in production environment configuration file use paths like s3:\your_bucket_name\path\in\bucket.
Hope it helps.

Spring Boot JSP

Is there any simple way to generate Spring Boot Mvc project for .jsp views?
I've tried to create project in similar way like Spring Boot Rest project, but it's not soo easy for me. I've tried to use official Spring Boot Mvc jsp sample, but when I try to run this I get exception like this:

This blog post explains what steps you should take and why. Its fairly easy and I've fixed it myself.
TD:LR
Add Maven Dependencies
In order to enable JSP support, we need to add a few dependencies to our new project in pom.xml.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
Place the JSP templates under src/main/resources/META-INF/resources/WEB-INF/jsp/
As I know, the spring boot default page technology is thymeleaf and the official recommends us to use it.
If you want to use jsp, you could do some configuration.
The following steps may be useful.
1. Creating src/main/webapp/WEB-INF/jsp folder.
2. Modify application.properties file.
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
3.Add jar support for jsp. You could add the followings maven repository to your project pom.xml file.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
Hope it helps. Any concerns, please feel free to let me know.
Add below dependencies to your POM file:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
Create below structure
/src/main/resources/META-INF/resources
Now the above folder is equivalent to your WebContent folder. Inside this you can put your static contents. Add WEB-INF folder here and now you can place your JSP files like any other web project.
In your application.properties file add below:
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
Any chance you're running in IntelliJ? I've noticed this issue as well and the solution is to remove the <scope>provided</scope> from the spring-boot-starter-tomcat dependency, like this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!-- <scope>provided</scope> -->
</dependency>
There's a bug in IntelliJ, causing it not to add provided dependencies to the classpath when running locally.
EDIT: Removing the provided scope might cause issues when you're going to run it within a servlet container, so be cautious about that, an explanation about how to fix that could be found in Run Spring-boot's main using IDE.
I have had similar problems, see the link to github.
jsf-spring-boot-2.1.6 parent use spring boot 1.4.0
everything has worked and there is no problems, believe it or not!
https://github.com/joinfaces/joinfaces-example-war
Adding dependency in POM file below
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
Full code avaliable on github link click here
Download the code and import the eclipse/STS using exiting maven project
Next to run the project.
Go to the package on com.chandrakumar.test.demo.
it has "DemoApplication.java" and right click the mouse and select run as
choose the java application.
The browser address bar type "http://localhost:8080/".
Following johnny's reply, I actually wasn't aware that JSP files could be ran while deploying the application as a JAR. Though apparently there are some extensions that I haven't heard of... Typically, a JSP application is deployed as a WAR, and all JSP-related files are located in the webapp/WEB-INF/ folder. You may need to add <packaging>war</packaging> to your POM if if you are comfortable packaging your application as a WAR. This doesn't sound like a bad idea if your application is not a microservice or does not utilize cloud-based technologies. But the majority of cloud-based technologies (excluding cloud-foundry and maybe some others) only support JAR packaging. In that case, you may want to use alternative templates such as Thymeleaf or FreeMarker, over JSP, if you decide to go the JAR route.
Use a maven run configuration with spring-boot:run as the "Command line" value.

Someone told me this is due to conflicting JAR files. But I don't know which JAR are conflicting. Could anybody could tell me which JAR files are conflicted. Any help is huge for me,Thanks!!!
I was facing similar problem. Actually, HibernatePersistence was not having ProviderUtil() method in entity jars. following combination works well.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.0.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.5.Final</version>
</dependency>
without list of JARs its quite hard to help you here.
Do you have maven in your project?
If so, you can use `mvn dependency:tree and see the tree of jars.
It can be that you're using hibernate that doesn't conform the JPA 2.0 Specification ProviderUtil class was introduced in JPA 2.0 as the doc states:
ProviderUtil
Yet another concern:
Are you running standalone or inside some container (app/web server or something)
If you're running a JBoss for example it has its own jars in the lib folder that can also clash with your jars. How exactly you're running your JUnit test?
If it's only a validation problem, consider using your own implementation of TraversableResolver instead of JPATraversableResolver or DefaultTraversableResolver.
Here's how to do it.
JPATraversableResolver might cause an unwished dependency to JPA. Here's a guy with a similar problem.
Of course, if you expect your application to JPA2-compliant, this is not a solution.
public class MyTraversableResolver implements TraversableResolver {
public boolean isReachable(Object traversableObject, Path.Node traversableProperty, Class rootBeanType, Path pathToTraversableObject, ElementType elementType) {
return true;
}
public boolean isCascadable(Object traversableObject, Path.Node traversableProperty, Class rootBeanType, Path pathToTraversableObject, ElementType elementType) {
return true;
}
}

selenium.waitForPageToLoad("30000");
Thread.sleep(5000);
assertTrue(selenium.isTextPresent("regexpi:Welcome"));
selenium.stop();
}
Can anyone help me please?
thanks in advance
Your pom.xml is missing, so hard to judge what's going wrong.
However, in a simple test project, I only need in my pom.xml the following in the "dependencies" section (note, I'm using Selenium 2.22.0 instead of 2.8):
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<scope>test</scope>
<version>2.22.0</version>
</dependency>
I invoke my tests using TestNG, but it should also work with JUnit.
My test case looks as follows. I stripped out everything related to proxy settings, so the example could probably even be simplified:
FirefoxProfile profile = new FirefoxProfile();
FirefoxBinary firefoxBinary = new FirefoxBinary();
WebDriver driver = new FirefoxDriver(firefoxBinary, profile);
driver.get("http://www.google.com");
Assert.assertEquals("Google", driver.getTitle().trim());
So one problem could be that you are using an outdated version of Selenium (2.8). Also the way you set up your DefaultSelenium looks wrong to me. Also, for Firefox you don't need the Selenium server running.
Another thing I don't understand is the wait for 30 seconds directly after starting selenium. What are you waiting for?
The Maven Cookbook answer of Running a Selenium Test with Maven.
As #Ozyman has pointed out it looks like you have not started the Selenium Server. The Selenium Server must be running in the background if you want to use Selenium RC to create your tests.
You can use the Selenium Maven Plugin to launch the Selenium Server before executing integration tests by adding the the following plugin configuration to ... .
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>selenium-maven-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>pre-integration-test</phase>
<goals>
<goal>start-server</goal>
</goals>
<configuration>
<background>true</background>
</configuration>
</execution>
</executions>
<dependencies>
<!-- Get the plugin to use the latest version of Selenium drivers -->
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-server</artifactId>
<version>2.26.0</version>
</dependency>
</dependencies>
</plugin>
You can turn your unit test into an integration test simply by renaming it from PersistenceTest to ITPersistenceTest. The Maven Failsafe Plugin will run the integration tests if you add the following plugin configuration to ... .
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.12.4</version>
<executions>
<execution>
<id>run-integration-tests</id>
<phase>integration-test</phase>
<goals>
<goal>integration-test</goal>
</goals>
<inherited>false</inherited>
</execution>
</executions>
On the site for the Selenium Maven Plugin there is guidance of how to use the force the Maven Surefire Plugin to run as part of the integration-test phase of the build life cycle.
If you are going to be writing a lot of Selenium based unit tests you might find the Selenium JUnit 4 Class Runner useful in reducing the amount of boiler plate you need to add.
