Resource not injecting Datasource from web.xml - Java Framework - Payara Micro - NullPointerException

My Payara REST API is working fine without DB Connection, and also Postgres localhost connection works fine through DriverManager i.e.:
Connection connection = DriverManager.getConnection("jdbc:postgresql://localhost:5432/postgres", "postgres", "pass#123")
However, Datasource for postgresql in web.xml & Resource is throwing NullPointerException in below code:
public class AppService {
#Resource(name="java:global/esWf")
DataSource ds;
public Response test (
...
Connection conn = ds.getConnection();

I have also tried replacing url with separate elements for server, port, db name!
This is first time I am trying to connect via Datasource & Resource, and could be am missing something minor!

This looks like the same issue as in resource injection in cdi bean.
Injection using #Resource doesn't work in plain CDI beans and JAX-RS resources. It only works in enterprise beans.
You have 2 options:
turn your bean into a stateless EJB - just add #Stateless annotation to the class:
#Stateless
#RequestScoped
#Path("app")
public class AppService {
#Resource(name="java:global/esWf")
DataSource ds;
public Response test (
Create a CDI producer and then inject the datasource as a CDI bean. The best practice is to use a qualifier to mark which DS you want to inject (in case there are multiple datasources in the app):
#Qualifier
#Retention(RUNTIME)
#Target({METHOD, FIELD, PARAMETER, TYPE})
public #interface Eswf {
}
---------------
#RequestScoped
public DsProducer {
#Produces
#Resource(name="java:global/esWf")
#Eswf
Datasource eswfDatasource;
}
------------------
#RequestScoped
#Path("app")
public class AppService {
#Inject
#Eswf
DataSource ds;
public Response test (
P.S. I think that you also need to change the JNDI name to use the java:app/ namespace instad of java:global/ because the DS should be available only to the deployed application. You can test whether you can retrieve the DS by JNDI name using `new InitialContext().lookup("java:global/esWf"). That should work anywhere in your application, not only in EJBs.

Generate swagger.json

I have a java project (tomcat webapp) with some REST Api. I want to generate swagger documentation for them. I started from this tutorial (github).
I don't have maven we use an ant task. I included swagger-annotations-1.5.0.jar and all jar that cames with swagger-jaxrs JAR 1.5.0 version( I can include a complete list if it is useful)
I've annotated some method and I have a configuration class like this:
#ApplicationPath("/api")
public class Configurator extends Application {
public Configurator() {
init();
}
private void init() {
BeanConfig beanConfig = new BeanConfig();
beanConfig.setVersion("1.0.0");
beanConfig.setSchemes(new String[]{"http"});
beanConfig.setHost("myserver.it:8080");
beanConfig.setBasePath("/swagger-demo/api");
beanConfig.setResourcePackage("myserver.rest");
beanConfig.setTitle("RESTEasy, Swagger and Swagger UI Example");
beanConfig.setScan(true);
}
}
when I deploy it agains tomcat 9 I can see this log in localhost.log file

If I try to reach http://myserver.it:8080/swagger-demo/api/ this give me 404 error.
I read this post about this error (here) but I really can't say what's wrong. I'm strugglin.
Any hints would be appreciated

I answer to myself since I finally find a solution. Problem was inconsistency with libraries. I solved using this site Jar download, that gives me all the dependencies. Then I compare some libraries that I already jave in my project and in caso of conflict I choose the newest one.

EJB 2.1 throwing wrapped remote exception in cluster

We're in the processing of moving a Weblogic 10.3.6 app to Weblogic 12.2.1.2. We have many EJB 2.1 beans that form part of the app. We've hit a strange problem with some of these beans.
When we have 1 ejb call another and this bean throws a checked exception (e.g. RuleException extends Exception) this is thrown as a RemoteException (RemoteEJBInvokeException). This only occurs if the app is running in a cluster. If I deploy against a standalone jvm it works fine.
The general EJB pattern is a Facade pattern. In the Facade bean we use a standard JNDI lookup to locate the Home and then run the create method to return the business interface/impl
InitialContext ctx = new InitialContext();
ReportManagementHome reportManagementHome = (ReportManagementHome) ctx.lookup("ReportManagement");
ReportManagement reportManagement = reportManagementHome.create();
ReportManagement bean runs the business logic and throws a RuleException.
This is an example method in the facade that calls the 2nd bean:
public String doTest() {
String s = null;
try
{
s = reportManagement.doValidate();
}
catch ( RuleException re )
{
rollBack();
} catch (RemoteException e)
{
e.printStackTrace();
}
return s;
}
Here is the doValidate() method in the 2nd bean:
public String doValidate( )
throws RuleException, CustomException
{
int test = 1;
if (test == 1)
{
throw new RuleException();
}
return "Hello";
}
Although the RuleException is correctly reached and thrown, by the time the facade catches it it is a RemoteException.
This is an example list of the ejbs/interfaces:
ReportManagement
ReportManagementBean
ReportManagementFacade
ReportManagementFacadeBean
ReportManagementFacadeHome
ReportManagementFacadeLocal
ReportManagementFacadeLocalHome
ReportManagementHome
ReportManagementLocal
ReportManagementLocalHome

Any guidance in this matter will be much appreciated.

This was fixed in a patch by Oracle on my request. The link for that patch is here Patch Link. You will need an Oracle Support log on to be able to access it.

This:
<enable-call-by-reference>true</enable-call-by-reference>
causes your remote calls in the same JVM to have local call semantics, including exception handling.

}

Error was because dispatcher Servlet file. The Correct way of declare entitymanagerfactory was different. DatabaseInitilizer Class is used to intialize the database username and password in a encrypted format.

Where is passwordEncoder being constructed and set in the DataBaseInitializer? It looks like its still null when initDataBase() is called here:
User userUser = new User("user", this.passwordEncoder.encode("user"));

Your XML files are referencing an old version of Jetty.
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
The org.mortbay.jetty namespace is for Jetty 6 or older versions of Jetty, (all of which have been EOLd for years now).
That entire XML document is wrong for Jetty 9, from the DOCTYPE, to the class references, even to the structure.
The <SystemProperty> element references a "jetty.home" variable that isn't used in jetty embedded (its only there for the jetty distribution, aka start.jar). The jetty-http-spi.jar doesn't even set or use this property.
The use of the Jetty Context XML Deployable is a feature that jetty-deploy.jar provides, however, that sort of deployable is not supported by the com.sun.net.httpserver.HttpServer concepts, either as a standalone deployable, or an internal WEB-INF/jetty-web.xml configuration.
That whole backend server war you are attempting to setup just cannot be on the com.sun.net.httpserver.HttpServer you started (not supported by that concept at a fundamental level)
Unfortunately, there is almost no troubleshooting available when you use the com.sun.net.httpserver.HttpServer techniques. Pretty much limited to logging output.
What does the logging output show?
Update: 2014, Oct 7:
About the logging output, lets see.
You are starting jetty via command line, using the Jetty 9.2.3 distribution.
That act is completely unrelated to your BackendServer use of com.sun.net.httpserver.HttpServer.
This would result in 2 different servers.
The standalone Jetty 9.2.3 distribution server
The com.sun.net.httpserver.HttpServer server
You have essentially 2 errors showing in those logs.
First is ...
java.lang.ClassNotFoundException: org.mortbay.jetty.webapp.WebAppContext
That's because you are using Jetty 6 techniques for Jetty 9. That class (actually package namespace) doesn't exist in Jetty 9.
That class (in Jetty 9) would be called org.eclipse.jetty.webapp.WebAppContext, see Configuring a Specific Web App Deployment in the Eclipse Jetty documentation website for details.
You will have to analyze and adjust most things in your example XML file to fit the realities of the nearly 200 releases since Jetty 6 and Jetty 9. Far too much time has elapsed between Jetty 6 and Jetty 9 to list what has changed. It would be equivalent to listing the differences between a Ford Model 18 and a Tesla Model S (it would be a huge list that would essentially mean 'everything' and be useless to work off of)
The other error ...
FAILED ServerConnector#1d402894{HTTP/1.1}{0.0.0.0:8080}:
java.net.BindException: Address already in use
means that this server cannot bind to port 8080, as some other server is already there.
This makes sense, as your BackendServer is also on port 8080 (per your example code).
Don't try to mix embedded-jetty and com.sun.net.httpserver.HttpServer, you will only tear your hair out trying to force com.sun.net.httpserver.HttpServer into doing what you want.
Consider using straight embedded-jetty + jersey servlet instead.
There's lots of examples of this technique online and in StackOverflow.
Here's the first one I found that had example code showing how to setup the ServletHolder for the jersey ServletContainer along with some relevant init parameters to configure it. Configuring Jersey + Jetty + JSP
