Timing issues sometimes cause autodeployment to fail in domains that are configured to support clusters. The issue is not observed in domains that do not support clusters.
Use one of the following solutions:
Use autodeployment as follows:
Automatically deploy individual applications sequentially.
Introduce a delay between autodeployments of individual applications
Deploy applications manually by using either the Admin Console GUI or the command line.
The following exception is thrown in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher.
Use of the bundled ANT for things outside the Enterprise Server is not recommended.
The application-specific classloader (applibs or --libraries) is not used by the JSP compilation. As a result, JSPs referencing these JARs will not compile.
No known solution.
