NullPointerException when publishing with Geronimo Eclipse Plugin v2.1.7

Hi everybody,

I just updated to Geronimo Eclipse Plugin v2.1.7, and now I get a 
NullpointerException whenever I try to publish to the server:

java.lang.NullPointerException
at java.util.concurrent.ConcurrentHashMap.put(Unknown Source)
at 
org.apache.geronimo.st.core.internal.DependencyHelper.getEnvironment(DependencyHelper.java:442)
at 
org.apache.geronimo.st.core.internal.DependencyHelper.reorderModules(DependencyHelper.java:109)
at

at 
org.eclipse.wst.server.core.internal.Server$PublishJob.run(Server.java:337)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

The project I used for testing is the one described here:
https://cwiki.apache.org/GMOxDOC21/5-minute-tutorial-on-enterprise-application-development-with-eclipse-and-geronimo.html

The exception disappears when switching back to 2.1.6 of the eclipse plugin

I'm using Eclipse 3.6.1

Any ideas?

Martin

Hi all,

Fixings for https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-689 and
https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-690 are included in
Apache Geronimo Eclipse Plugin (GEP) 2.2.1, which works with both Geronimo
server 2.2.1 and Geronimo server 2.1.7.

You can install GEP 2.2.1 through eclipse update site
http://www.apache.org/dist/geronimo/eclipse/updates/ or manual install it by
downloading from http://www.apache.org/dist/geronimo/eclipse/2.2.1/.

I believe this general problem has been fixed in https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-689 and https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-690

You can apply their associated patches and build GEP from source. IIUC, you can also work around this problem with the following steps (as described by Janet, previously:

 
1. In SampleUtility project, export the project into a jar, e.g., SampleUtility.jar
2. In SampleEAR project, create a lib folder under EarContent folder, and then copy SampleUtility.jar into lib folder
3. In SampleEJB project, add SampleUtility.jar as external JARs in Libraries tab of java build path panel
 
With above changes, the SampleEAR project can be published successfully in eclipse.

Dear All,

I have the same problem in Envioroment:

Yeah, this should be a workaround before
https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-690 is fixed.

I don't see the intention to drop the support for Utility Project in 2.1.7.
There should be a bug somewhere broken this function. For statis jar, I
agree plain old java project is enough.

is that a workaround, or the proposed solution?

Replacing a Utility Project with a static jar sounds very much like the 
discussion brought up in
http://apache-geronimo.328035.n3.nabble.com/Eclipse-Utility-Projects-with-2-1-2-td339278.html
and
https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-513

I guess my question is - has support for Utility Projects been dropped 
with 2.1.7 (since it it's packaged as a static jar, one could just use a 
plain old Java project as well)?

Best regards,
Martin

Martin,

For Utility project, the solution is

1. In SampleUtility project, export the project into a jar, e.g.,
SampleUtility.jar
2. In SampleEAR project, create a lib folder under EarContent folder, and
then copy SampleUtility.jar into lib folder
3. In SampleEJB project, add SampleUtility.jar as external JARs in Libraries
tab of java build path panel

With above changes, the SampleEAR project can be published successfully in
eclipse.

Hi Martin,

Good findings.

I skipped the instructions to delete ejbModule/META-INF/openejb-jar.xml
during my testing so it worked well. If I delete this file I can reproduce
your exception in my environment.

I opened two JIRAs.

1. https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-689
NullPointerException
when publishing with Geronimo Eclipse Plugin v2.1.7 (I think it needs either
code or document update or even both)
2. https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-690
NullpointerException
occurs if one adds a "Utility Project" to the EAR

Thanks very much for catching the problem.

Re: NullPointerException when publishing with Geronimo Eclipse Plugin v2.1.7

Hi again,

after a little bit of debugging, it seems to me that the problem is that 
I've deleted ejbModule/META-INF/openejb-jar.xml in the SampleEJB 
project, as is suggested in
https://cwiki.apache.org/GMOxDOC21/5-minute-tutorial-on-enterprise-application-development-with-eclipse-and-geronimo.html

Since that file is gone, the check
file.getName().equals(GeronimoUtils.OPENEJB_PLAN_NAME) && file.exists()
in DependencyHelper Line 538 is false, so "environment" in 
DependencyHelper Line 442 is never set for the EJB project.

Did I misread the instructions to delete ejbModule/META-INF/openejb-jar.xml?

By the way, a NullpointerException also occurs if one adds a "Utility 
Project" to the EAR (since there's only handling for Web, EJB, EAR, RAR 
and AppClient modules).

Maybe I'm simply misunderstanding how Geronimo works (I've been using 
JBoss for a long time, and have just started using Geronimo).

I'll send them off list

Please don't attach files to mailing list emails. Create a Jira issue and attach the files there...

Thanks Martin for your information.

Let me try to find a Windows Vista 64 machine tomorrow, and try the scenario
again before turning back to you.

Another investigation is that let me try your projects in my environment,
can you attach your projects in the mail?

First try:
1. Clean "Eclipse IDE for Java EE Developers" 3.6.1 from
http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/helios/SR1/eclipse-jee-helios-SR1-win32.zip
2. Geronimo Eclipse Plugin v2.1.7 installed from
    http://www.apache.org/dist/geronimo/eclipse/updates/
3. Windows Vista 64 (running 32-Bit JDK)
4. Sun/Oracle JDK 1.6.0_23 (32-Bit)
5. Clean Geronimo Server 2.1.7, installed from
http://www.apache.org/dyn/closer.cgi/geronimo/2.1.7/geronimo-tomcat6-javaee5-2.1.7-bin.zip

Second try:
1. Clean "Eclipse Classic" 3.6.1 from
http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops/R-3.6.1-201009090800/eclipse-SDK-3.6.1-win32.zip
2. Geronimo Eclipse Plugin v2.1.7 installed from
    http://www.apache.org/dist/geronimo/eclipse/updates/
3. Windows Vista 64 (running 32-Bit JDK)
4. Sun/Oracle JDK 1.6.0_23 (32-Bit)
5. Clean Geronimo Server 2.1.7, installed from
http://www.apache.org/dyn/closer.cgi/geronimo/2.1.7/geronimo-tomcat6-javaee5-2.1.7-bin.zip

I've also tried both approaches using Sun/Oracle JDK 1.5.0_22 - with the 
same result.

Switching back to version 2.1.6 of the eclipse plugin makes the error go 
away.

Is there anything else I can try?

Best regards,
Martin

Hi Martin,

Geronimo Eclipse Plugin 2.1.7 was tested successfully against this senario
before releaseing
https://cwiki.apache.org/GMOxDOC21/5-minute-tutorial-on-enterprise-application-development-with-eclipse-and-geronimo.html

And I just double checked again with following environment, and can not
reproduce your exception.

1. clean eclipse 3.6 SR1
2. installed from http://www.apache.org/dist/geronimo/eclipse/updates/
3. windows XP SP3
4. Sun JDK 1.5.0_22
5. Geronimo Server 2.1.7

Could you let us know your environment for problem investigation?
