Hi Milen, I have a question regarding your environments. Is it specific to your environment or is this not a environment specific issue?

[Milen Dyankov]

This is what patching-tool info says on my machine where I can reproduce this:

Product information:
 * installation type: binary
 * build number: 6210
 * patching-tool version: 12
 * plugins: no plugins detected

Currently installed patches: administration-2-6210, asset-framework-1-6210, collaboration-2-6210, development-1-6210, document-management-2-6210, dynamic-data-lists-1-6210, platform-2-6210, search-2-6210, user-interface-2-6210, wcm-core-2-6210, web-content-2-6210

Available patches: development-1-6210, dynamic-data-lists-1-6210, platform-2-6210, document-management-2-6210, asset-framework-1-6210, web-content-2-6210, user-interface-2-6210, collaboration-2-6210, wcm-core-2-6210, administration-2-6210, search-2-6210

  [*I] search-2-6210 :: Installed; Will be installed. :: Built for Liferay

Hopefully this will help you figure out how it was fixed as it is definitively an issue on clean 6.2 EE SP1 downloaded from customer portal.

Sorry for reopening but you stated you tested on WebLogic 12.1.1. Can you please check on 12.1.2 version as this seems to be the version that everyone confirming the issue is using.

[Adorjan Nagy (Inactive)]

Hi guys,

By adding the <package-name>org.xmlpull.*</package-name> into the <prefer-application-packages> block of the weblogic.xml, and redeploying the application, the pages are imported successfully in step #4.

Regards,
Adorjan
