Struts 1.1B: Classpath entries in Manifest.mf file of struts.jar
Unlike Struts 1.0, Struts 1.1 is built upon various libraries from the
Jakarta Commons project. As a result, these necessary libraries are listed
as classpath elements in the "manifest.mf" file of the "struts.jar" file.
More specifically:
Class-Path: commons-beanutils.jar commons-collections.jar
Class-Path: commons-dbcp.jar commons-digester.jar
Class-Path: commons-logging.jar commons-pool.jar
Class-Path: commons-services.jar commons-validator.jar
Class-Path: jakarta-oro.jar
My team is using WebLogic 6.1 SP 2. If our "struts.jar" contains a
"manifest.mf" with the above classpath elements, then we have to include the
"struts.jar" file in the classpath used to boot WebLogic (even though the
"struts.jar" file is included in the "WEB-INF\lib" folder). Otherwise, we
get the exception listed below. Conversely, if we take the classpath
elements out of the "manifest.mf" file, then the "struts.jar" does not need
to be included in the WebLogic classpath, and the server boots fine. Can
anyone explain this? Thanks, JOHN

I have deployed struts 1.1b2 apps to Weblogic 6.1sp3 without modifying server
classpath. May be its a weblogic sp2 issue.
