1118264.1 WLS 10.3: Intermittent XA error:XAResource.XAER_RMERR  WebLogic server keeps track of the usage of XA resources.  If none of
the outstanding requests to the resource was replied in the last

XAER_RMFAIL is returned to all requests to the resource without actually
making the call to the resource.
The string "X-Powered-By: Servlet/2.4 JSP/2.0" is showing up in the servlet response header.
How to stop Weblogic from including servlet/JSP version details in the x-powered-by HTTP response header.
1059713.1 The value for 'DISTRIBUTED_LOCK_TIMEOUT' on Oracle Database is set lower than the JTA timeout on WLS. If timeout setting is not tuned properly on the database then 'XAER_NOTA' is seen in the logs.

This sample guides on how to invoke webapp and EJB which are deployed as libraries from a separate EAR file.
1575676.1 Get application root path correctly on environment that deploy application both with war and directory  If
deployment mode is nostage, we can deploy web application with war
format, when deploy web application with war format, WebLogic copy files
in the war to temp directory(_WL_user), and load all files from the
temp directory, when deploy web application with directory mode,
WebLogic just copy a part of files to temp directory, and many files
such as jsp, servlet and config files do not copy to temp directory, and
WebLogic load files from the application directory
1557187.1 Loading Order of Sibling Jar Files in WebLogic  A Web application contains two  libraries (lib1.jar and lib2.jar) in WEB-INF\lib. Same Java classes and resources files  exist in both libraries.
The question is to know which library will be loaded when loading these classes or resources files.
1505375.1 WLS12.1.1: NullPointerException in Glassfish JAXB V2.2.4   Following document http://docs.oracle.com/cd/E24329_01/web.1211/e24964/data_types.htm#CIHBHDGI to
