IronJacamar Eclipse Plugin Java Version Problem

[Robert Corcoran]

I'm trying to install the IronJacamar Eclipse plugin. I follow the instructions by copying the ironjacamar-eclipse.jar to the %ECLIPSE_HOME%\plugins directory. but when I open Eclipse and go to the Window/Preferences page and click on IronJacamar, the following error occurs:

Unable to create the selected preference page.
org/jboss/jca/eclipse/preferences/IronJacamarPreferencePage : Unsupported major.minor version 51.0.

My Java version is 1.7.0_55 and the compiler compliance level is set to 1.7. I would think this should be sufficient for the IronJacamar plugin. Has anyone else run into this issue?

Thanks,

Bob

Hi Bob,

I don't think you said which version of IronJacamar and Eclipse you are using. As you likely know, 51.0 is JDK7 which was what the version of IJ you are using was compiled with by inference. What I imagine is happening is eclipse is running using an older JVM for some reason.

I do know you can put:

-vm

C:/Program Files/Java/jdk1.8.0_65/bin

(as appropriate)

In your eclipse.ini to know the version Eclipse is launching with.

Hope this helps,

Tom

Hi Tom,

Thanks for your reply. You are right. Our Eclipse version was running using a 1.6 jdk. .We are going to upgrade our Eclipse version (we are using JBDS 7.1, and for some reason it is not starting when we point to our 1.7 jdk in the ini file). We are using IronJacamar version 1.2.4.Final. 

Thanks again for your help.

No problem!
