I'm trying to use HikariCP library for PostgreSQL connection pools in Java. I am using Maven, and I'm getting this error: java.lang.ClassNotFoundException: org.postgresql.Driver.
I have tried using different versions of the PostgreSQL driver, but none have worked to my advantage. (I have done more, but I've been faced with this problem, that I have not taken note of)
org.postgresql.ds.PGSimpleDataSource, org.postgresql.Driver and com.impossibl.postgres.jdbc.PGDataSource still produce this error, even though it is said in the HikariCP guide to use either the first or third. The second I found from research.
My maven:

What I'm using to produce this error:
try {
Class.forName("org.postgresql.Driver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
System.out.println("Failed to load.");
}
HikariConfig config = new HikariConfig("database.properties");
ds = new HikariDataSource(config);
(The constructor HikariDataSource(config); produces this error aswell)
I believe the reason why this is happening is that the driver is not being made into the classpath - however, all efforts I have tried can't seem to do this. This problem of the driver not being in the final jar (to my belief):
.
Actual error:

Adding <scope>compile</scope> produced same results - did not work.
You can specify a filter to include the driver artifact in the shaded JAR:
<configuration>
<minimizeJar>true</minimizeJar>
<filters>
<filter>
<artifact>org.postgresql:postgresql</artifact>
<includes>
<include>**</include>
</includes>
</filter>
</filters>
For more details: Selecting Contents for Uber JAR.
The issue occurs due to the (unfiltered) <minimizeJar>true</minimizeJar> configuration in your POM, and the fact that the driver class is not used at compile time.
maven-shade-plugin on minimizeJar:
When true, dependencies will be stripped down on the class level to only the transitive hull required for the artifact.

I'm trying to create a uber jar from my jersey project in eclipse using maven. When running the project in eclipse it works well, but when I try to export the project to a jar file using maven the server seems to miss the JSON Provider.
The server starts without warnings, but every request to the server is answered with a HTTP error 415 (which is why I assume that the JSON Provider is missing like described here)
I'v already tried many dependencies, build options, ... but non of them is working. I also tried the the answer to this question, which seemed to be related, but it didn't work either.
This is the pom.xml I'm using:

Adding this the build succeeds (like it did before), but starting the server I get the following errors:

(this is repeated serval times; full stacktrace was too long to be added here)
The server seems to start anyway. When I try to connect to this server the HTTP error changes to error 500 (internal server error).
I am trying to use the new Apache Commons Text new random string generator, but I can't find any usage on the Internet on how to properly import it. Maven builds successfully, but when I try to run my jar file from the command line with the following command
java -cp target/my-app-1.0.jar com.mycompany.app.App

If you want to run you application from a jar, you will need an exploded jar. The default class loader will not find the apache jar from your jar.
You can use the shade plugin to create an exploded jar. Add something like below to your pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<phase>package</phase>

</manifestEntries>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Then, you can run with the following:
java -jar target/my-app-1.0.jar
I am using the following dependecy in my pom.xml from maven:
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.55</version>
</dependency>
After running the project inside eclipse everything is working fine.
By using the export feature from eclipse, creating a runnable jar file, including all dependencies also everything works fine.
No other parameters or configurations in eclipse are set.
Only when i am running a mvn built something seems to be wrong.
(Maven built runs without any error or warnings)
--> Dependencies are all included.
An error occurs in that moment when it tries to establish an https connection, the place where this bouncycastle library is used.

So for me it seems like something is missing during the maven built process.
Is it required to sign one of the jars?

I am getting the runnable jar with:
mvn clean install
EDIT:
Manifest file from eclipse export

Class-Path: .
Rsrc-Main-Class: view.Dashboard
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader
-> seems like there are still dependencies to eclipse
Problem seems to be here that the dependency from bouncycastle must be signed. The jar is not signed anymore if maven repacks it inside another jar.
Solution is to keep all dependecies next to the jar file and add a classpathdirectory. Now the main jar can use directly the signed jar.
(However i would really prefer to have one single jar file)
I am trying to integrate Apache Spark Streaming and Apache Flume by following this guide. I am trying to set this up in a MapR Sandbox.
When I submit the example: JavaFlumeEventCount, everything works fine and it counts all the events. I use one terminal to start the Spark job and another terminal to start Flume.
When I try to use the example code in my own project and create a jar it runs fine, but events are not being counted and it generates the following exception in the Flume log:
19 Mar 2015 08:32:46,397 ERROR [SinkRunner-PollingRunner-DefaultSinkProcessor] (org.apache.flume.SinkRunner$PollingRunner.run:160) - Unable to deliver event. Exception follows.

I gues that the problem is in this line:
public static void main(String[] args) {
ModernSoft ms = new ModernSoft();
StringBuffer classpath = new StringBuffer();
ClassLoader applicationClassLoader = ms.getClass().getClassLoader();
if (applicationClassLoader == null) {
applicationClassLoader = ClassLoader.getSystemClassLoader();
}
URL[] urls = ((URLClassLoader)applicationClassLoader).getURLs();
for(int i=0; i < urls.length; i++) {
classpath.append(urls[i].getFile()).append("\r\n");
}
System.out.println(classpath.toString());
ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:**/applicationContext*.xml");
//org.springframework.context.ApplicationContext ctx = new FileSystemXmlApplicationContext("C:\\Documents and Settings\\BK\\workspace\\ModernSoft\\src\\main\\resources\\applicationContext.xml");
DataSource ds = (DataSource) ctx.getBean("dataSource", DataSource.class);
String[] beans = ctx.getBeanDefinitionNames();
I have all jar in maven dependencies, but still i cant solve this wired problem.
Please help me.

UPDATE
Uberjar works like a charm
Now i have another problem, after run jar file i get:
Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to lo

And also i cant add or change entities.
After make customerDao.save(Customer) i get only in hibernate
Hibernate: select max(id) from customers
But no record in DB shows up.
I believe that you are running jar file from command line using java -jar In this case you will need to specify all jars which needs to be included in classpath using -classpath option.
Another option would be using Maven uber jar (jar which contains all depencies.)
The various spring jars each contain their own spring.handlers and spring.schemas files named identically, meaning the shader/uberjar plugins will pick one of them and other namespaces will fail to work.
See Invalid or corrupt JAR File built by Maven shade plugin for a shader plugin configuration merging the otherwise conflicting files. That example does have the configuration element in a weird location, my version is:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
<configuration>
<transformers>
<!-- must be SURE to do this with both spring.handlers and spring.schemas.
otherwise you won't be able to use them in the spring config files. -->
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
</transformers>
</configuration>
</plugin>
