Hello,

I need to launch my WAS application to use WAS 6.1’s “parent classloader last” policy.
Unfortunately I could not spot such setting in MyEclipse Blue and the WAS connector.

I can change the classloader policy in WAS 6.1’s Admin Console, however
whenever I redeploy with MyEclipse Blue, these settings are overwritten to “parent classloader first”.

I am deploying as described in
http://www.myeclipseide.com/documentation/quickstarts/blueedition/blue_connectors/#web_deploy_traditional
on a local WAS 6.1 instance, using MyEclipse Blue 8.6.

I’d appreciate your help!

thud,

If you edit the application.xml file in Blue (the WebSphere Application Editor is the default editor), one of the editor tabs will mention “Application Configuration”. On this tab, you can set the classloader policy for your application. The setting is stored in your EAR project and it will be persisted across deployments.

Hope this helps.

Thanks for your reply.

The “Application Configuraion” editor tab throws an “Unhandled loop exception” when I attempt to open my application.xml in MyEclipse Blue 8.6-Blue-20100723.

Thanks for your help!

Hi,

sorry, without the editor / looking at the xsd schema, I failed to understand how to set the classloader policy in application.xml. However I found posts on how to change the the policy in deployment.xml. Again I am encountering an exception when opening this file in the editor associated in MyEclipse Blue (see below).
Manual changes in deployment.xml are not reflected in WAS admin console.

My MyEclipse trial period expires tomorrow and I am not impressed… 🙁
Input would be appreciated.
