Seam-Guice injection results in null pointer on POJO class that is not part of EJB or WAR

[jusyes]

using Sean guice combination inside jboss 430 works on class that is annotated as stateless EJB, but when EJB3 class calls helper class the Injection does not work.
The other difference is the helper class is in another jar file which has empty seam.properties file so that seam can load it as component..

Below is snippet of code where it fails with exception trace below.. any pointers why this would be...

Thanks
Justin

@Name("externalClientImpl")
@Guice("CCRTGuiceInjector")
public class ExternalClientImpl implements ExternalClientInterface {

        @Inject @Named("gateway.UserId")
        private String userId;

        @Inject
        private GatewayAccessor gatewayAccessor;

        public Object processServiceRPC(Object obj, String serviceName, String bindingFileName, String expectedObjectName) throws Exception {
                log.debug("is : " + userId);
                log.debug("gatewayAccessor is : " + gatewayAccessor);
                
                Inputs inputs = gatewayAccessor.convertJavaObjToGatewayRPCFormat(obj, serviceName);

Hi Justin!

Could you please be more specyfic? I can't tell which helper class you mean :)

As far as I understand Guice injection doesn't work when you call a class that is in the another jar. Does it work in the same scenario when a class is in the same jar?

Cheers,

Hi pawel -

Hope the below makes it easier, it is working across jar's from EJB class but not from POJO within same jar OR different jar.

Scenario 1(works) : foo.java is stateless EJB ( part of xyzEJB.jar) this references injected class temperature.java from 123POJO.jar
code snippet:

@Stateless
@Name("AccountService")
@Guice("CCRTGuiceInjector")
public class AccountServiceImpl implements AccountServiceInterface {

        private static Logger log = LoggerFactory.getLogger(AccountServiceImpl.class);

        @In FacesMessages facesMessages;
        
        @In(required=false,create=true,value="AccountBean")
        @Out(value="AccountBean",scope=ScopeType.SESSION)
    private Account account = new Account();

        @Inject @Named("gateway.UserId")
        private String userId;
        public Account retrieveAccountSummary(){
                log.debug("**********userId is : " + userId);

Output:
2008-10-07 16:02:16,968 DEBUG [com.ccrt.services.account.AccountServiceImpl] **********userId is : jyesudasan
2008-10-07 16:02:16,968 DEBUG [com.ccrt.services.account.AccountServiceImpl] **********gatewayAccessor is : com.ccrt.util.gateway.GatewayAccessorImpl@c4f67b
2008-10-07 16:02:16,968 DEBUG [com.ccrt.services.account.AccountServiceImpl] **********gatewayAuthenticator is : com.ccrt.auth.GatewayAuthenticatorImpl@1124642

Scenario 2( does not work): bar.java is POJO (part of xyzEJB.jar) this references injected class temperature.java from 123POJO.jar
code snippet:

@Guice("CCRTGuiceInjector")
@Name("testGuiceClassLoaderIssue")
public class TestGuiceClassLoaderIssue {
        
        private static Logger log = LoggerFactory.getLogger(TestGuiceClassLoaderIssue.class);

        @Inject @Named("gateway.UserId")
        private String userId;
        @Inject
        private GatewayAuthenticator gatewayAuthenticator;      
        @Inject
        private GatewayAccessor gatewayAccessor;        
        
        public void processServiceRPC(){
                log.debug("++++++++userId is : " + userId);
                log.debug("++++++++gatewayAccessor is : " + gatewayAccessor);
                log.debug("++++++++gatewayAuthenticator is : " + gatewayAuthenticator);

Output:
2008-10-07 16:02:18,687 DEBUG [test.guice.TestGuiceClassLoaderIssue] ++++++++userId is : null
2008-10-07 16:02:18,687 DEBUG [test.guice.TestGuiceClassLoaderIssue] ++++++++gatewayAccessor is : null
2008-10-07 16:02:18,687 DEBUG [test.guice.TestGuiceClassLoaderIssue] ++++++++gatewayAuthenticator is : null

Scenario 3( does not work): foo.java is stateless EJB ( part of xyzEJB.jar), invokes fooHelper.java (part of 123POJO.jar) this references injected class temperature.java from 123POJO.jar

snippet and output same as Scenario 2

[jusyes]

just realized in earlier reply for scenario1 i did not copy couple of lines it is same as scenario 2.. just fyi below here if needed

@Stateless
@Name("AccountService")
@Guice("CCRTGuiceInjector")
public class AccountServiceImpl implements AccountServiceInterface {

        private static Logger log = LoggerFactory.getLogger(AccountServiceImpl.class);

        @In FacesMessages facesMessages;
        
        @In(required=false,create=true,value="AccountBean")
        @Out(value="AccountBean",scope=ScopeType.SESSION)
    private Account account = new Account();

        @Inject @Named("gateway.UserId")
        private String userId;
        @Inject
        private GatewayAccessor gatewayAccessor;
        @Inject
        private GatewayAuthenticator gatewayAuthenticator;

        public Account retrieveAccountSummary(){
                log.debug("**********userId is : " + userId);
                log.debug("**********gatewayAccessor is : " + gatewayAccessor);
                log.debug("**********gatewayAuthenticator is : " + gatewayAuthenticator);

Could you please show a code you use to call testGuiceClassLoaderIssue.processServiceRPC() (scenario 2)?

Does @In (not @Inject) works fine there?

-Pawel

[jusyes]

sure... The only reason i have it in EJB class was test to see if there was something different in injection.
ideally all this injection stuff is for utility/helper classes to deal with weather to execute Webservice or RMI, what Authenitcation mechanism to use and read property files for development and production. But it seemed to be bizzare it works from EJB and not POJO

TestGuiceClassLoaderIssue testGuiceClassLoaderIssue = new TestGuiceClassLoaderIssue();
testGuiceClassLoaderIssue.processServiceRPC();

GuiceSetupModule.java ( this is configured in components.xml)

package com.ccrt.guice;

import java.net.URL;
import java.util.Properties;

import com.ccrt.auth.GatewayAuthenticator;
import com.ccrt.auth.GatewayAuthenticatorImpl;
import com.ccrt.util.gateway.GatewayAccessor;
import com.ccrt.util.gateway.GatewayAccessorImpl;
import com.google.inject.AbstractModule;
import com.google.inject.Scopes;
import com.google.inject.name.Names;
public class GuiceSetupModule extends AbstractModule {
        @Override
        protected void configure() {
                System.out.println("GuiceSetupModule configure INVOKED");

                bind(GatewayAccessor.class)             
                .to(GatewayAccessorImpl.class)
                .in(Scopes.SINGLETON);                                          
                bind(GatewayAuthenticator.class)                
                .to(GatewayAuthenticatorImpl.class)
                .in(Scopes.SINGLETON);          
                Properties properties = loadProperties();               
                Names.bindProperties(binder(), properties);
          }                     

        
}

Well, you call testGuiceClassLoaderIssue as a normal class, not as a Seam component. Seam can't proxy a request, so obviously annotations and interceptors don't work. @In would't work as well :)

You have to obtain a reference to the testGuiceClassLoaderIssue component either @Injecting it or by lookup calling TestGuiceClassLoaderIssue testGuiceClassLoaderIssue = (TestGuiceClassLoaderIssue) Component.getInstance("testGuiceClassLoaderIssue").

This has nothing to do with differences between POJO and EJB3. I guess you called EJB3 component correctly and that is why it worked.

Let me know if this solves your issue :)

-Pawel

[jusyes]

Thanks, makes sense .. missed that in terms of trying to write quick test within jar file.
I changed the TestGuiceClassLoaderIssue to use Guice injection and it works, hence the scenario that does not work now is Scenario3.
Scenario3 is using Guice injection but the classes are in different jar, which coincides with your earlier comment that Guice Injection does not work on class in different jar, can you point me to where you came across this. trying to understand rationale and then might post on Guice forum to see if its resolved in 2.0 or any plans for that..

Thanks for your help Pawel...

[jusyes]

scenario 3 works as well across different jar, had new inside one of the methods.. did not realize i had not refactored that piece to use Guice Injection...

Thanks for all help... Have one more question for you had also posted in Guice Forum, what is best approach to bootstrap guice to make it available in EJB tier outside of seam invocation...
