Exceptions by running the rar-info.sh

[Wei Chen]

Hi,

I want to figure out the infomation of an RAR file. But as I run the 'rar-info.sh' against the RAR, I got some exceptions as follow:

...

]# ./rar-info.sh RaCPerf.rar

Done.

But the NotFoundClass 'de.pylon.ra.jni.CPFIF' is inside the RAR. What could be the problem?

Regards!

org.jboss.resource.deployment.DummyResourceAdapter doesn't exists anymore, maybe the resource adapter is hard coded against that class. Check your META-INF/ra.xml file.

You could also check what RAXAResource.java:62 does - maybe it assumes something about classloading.

Hi,

I just attached the ra.xml in my other post. The "org.jboss.resource.deployment.DummyResourceAdapter" is realy coded in the ra.xml.

How to check the "what RAXAResource.java:62 does"?

[Wei Chen]

Hi,

Now I run the 'rar-info.sh again as follow:

./rar-info.sh -classpath ./lib/* RaCPerf.rar

The error message "java.lang.ClassNotFoundException: org.jboss.resource.deployment.DummyResourceAdapter" is gone since this class is defined in 'jboss-jca.jar' and I copied this to the ./lib.

But how about the other two exceptions?

Further info:

I find the class 'de.pylon.ra.jni.CPFIF' is inside the RAR. But how to find out why this couldn't be initialized?

[Wei Chen]

Now, I insert the 'jboss-jca.jar' into the RAR and start the Jboss again. I got another error now as follow:

...

Caused by: org.jboss.jca.validator.ValidatorException: Severity: ERROR

Section: 19.4.2

Description: A ResourceAdapter must implement a "public int hashCode()" method.

Code: org.jboss.resource.deployment.DummyResourceAdapter

Severity: ERROR

Section: 19.4.2

Description: A ResourceAdapter must implement a "public boolean equals(Object)" method.

Code: org.jboss.resource.deployment.DummyResourceAdapter

...

According the document of Ironjacamar "http://www.ironjacamar.org/doc/userguide/1.1/en-US/html/ch07.html#validator_reports", this means that org.jboss.resource.deployment.DummyResourceAdapter is missing an equals and hashCode implementation.

I am not sure I can't use the old jar from Jboss EAP 5 and have to build a new RAR myself?

Don't insert jboss-jca.jar into the .rar -- that is not the way forward.

See the other thread, and then rerun the tool

for this the resource adapter needs to contain

• CPERF.dll
• CPERF.a
• CPERF.so

Otherwise you have to deploy the resource adapter as <transaction-support>LocalTransaction</> or <transaction-support>NoTransaction</> based on your stack trace...

Sorry, please ignore my last post. 

Now I've found the other *.so files and put them in the java.library.path. As I run it again, I got other exceptions as follow:

...

Done.

What could be the reason now?

[Jesper Pedersen]

Maybe due to https://issues.jboss.org/browse/JBJCA-1270 - you would need to check the source code of the resource adapter to verify.

But the report should be there, and you can use the sample deployment descriptor as a baseline.
