Does the Ironjacamar-1.2.4.Final just run on Oracle Java 1.7?

[Wei Chen]

I've tried first runing the 'rar-info.sh' on a LINUX machine with SUN Java 1.6.0_91 installed. But I got exception as follow:

# ./rar-info.sh

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/jboss/jca/as/rarinfo/Main : Unsupported major.minor version 51.0

Could not find the main class: org.jboss.jca.as.rarinfo.Main.  Program will exit.

Then I run it on a LINUX machine with Oracle 1.7.0_75 installed and it works.

IronJacamar 1.2 has Java 7 as baseline, with Java 8 as an option - http://www.ironjacamar.org/doc/developerguide/1.2/en-US/html/ch02.html#jdk

So far I know the IronJacamar is integrated in the Jboss EAP 6.X. I use now the Jboss EAP 6.3.3. But the Java verison on the machine is SUN Java 1.6.0_91. But as I start the Jboss, I don't have the "UnsupportedClassVersionError". What a version is used in Jboss EAP 6.X? How to check it?

Do you think it's better that we use the Java 7?

[Wei Chen]

I just check our LINUX machine and get following information:

]# yum list installed |grep -i IronJacamar

Seems the IronJacamar version integrated in the Jboss EAP 6.3.X is 1.0.28-1? Does this version have the Java 6 as baseline?

Yes, Red Hat Enterprise Application Platform 6.x makes use of IronJacamar 1.0, which has Java 6 as baseline.

IronJacamar 1.0 and IronJacamar 1.1 are no longer supported by the IronJacamar community.

What version of jca does IronJacamar 1.0 support? 1.5? oder 1.6?

Does IronJacamar 1.0 support the class "org.jboss.resource.deployment.DummyResourceAdapter"?

[Wei Chen]

I just downloaded the 1.0. But I find there are much less *.sh in it such as the ra-info.sh. Isn't it?

[Wei Chen]

Further question:

If we use the 1.2.4 to build a RAR, could it run on Jboss EAP 6.3.3 since the integrated version of IronJacamar is 1.0 in Jboss EAP 6.3.3?

IronJacamar 1.0 supports JCA 1.0 / JCA 1.5 / JCA 1.6 - see the user guide.

No, org.jboss.resource.deployment.DummyResourceAdapter is not supported by IronJacamar.

Yes, you can use the code generator to generate a skeleton for all versions of the Java EE Connector Architecture specification.
