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 maxXACallMillis ms, the resource is declared unhealthy.  In this state, 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.

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 to specify the Glassfish RI implementation of JAXB 2.2, modules/databinding.override_1.0.0.0.jar has been added to the front of their server CLASSPATHs.  However, upon redeployment of their web service applications, error is received, which matches the problem described in this thread:
