I installed Weblogic 12.1.3 and have had nothing but problems.
I didn't upgrade an existing domain. I created a new one and tried deploying the application to it. It immediately started bombing out on JSP compilation.
Compilation of JSP File '/WEB-INF/pages/common/layout/MainLayout.jsp' failed:
MainLayout.jsp:112:41: This attribute is not recognized.
<custom:UserMessage type="INFO" message="${TopInfoMsg}" messageContainerId="TopInfoContainDiv" messageDivId="TopInfoMsgDiv" hide="${empty TopInfoMsg}" />
I've tried the following to troubleshoot:
- Java 7 and Java 8 (problem occurs in both versions)
- Tried the JSP Backwards Compatibility setting in the WLS console
- Disabled JRebel
- Tried eliminating "xerces hell" as a problem by adding xml-apis to the
<prefer-application-packages>in weblogic.xml (also eliminated the tertiary dependency on that package in my Maven POM file). - Put the @page tag with pageEnconding="UTF-8" as the first line of the MainLayout.jsp file.
What I occasionally see is weblogic emptying the contents of the .tag files, but not always.
Any help or troubleshooting ideas would be appreciated.
