It looks like there is some problem inside the following class *"XsltTag.java"* (Which belongs to your Application only) com.qm.common.presentation.taglib.XsltTag.doEndTag(XsltTag.java:16)
Inside your "buttonbar.jsp" page u might be using some of the custom TagLibraries which are not correctly coded which is causing this issue.
Your Application Development team may be more useful in this case.

<BEA-101017> is a very generalized exception ... which is ommited by WLS if anything abnormal happens in the WebContainer specially woth any HTTP module Please see the description of this BEA Code:
BEA-101017 Error: [context] Root cause of ServletException. Description: [context] Root cause of ServletException, which the Web application container caught while servicing the request. Cause:The Web application container caught an unexpected exception. Action:Check the exception for the exact error message.
The most important thing in the stack trace is...*"the Cause of Exception is your application only.....even the line number also mentioned which is causing this issue....So Only application development team can help u in this."*
