java.lang.NoClassDefFoundError: org/apache/log4j/LogManager at Weblogic deployment

Question

When I Put ApacheDS LDAP librarians and its dependencies JARs into Weblogic shared library I am getting below exception.

I have log4j-1.2.17, slf4j-api-1.7.5 and slf4j-log4j12-1.7.5 in the classpath.

Can anybody help me out? What is wrong?

Problem solved. It due to the Spring framework use different version XML apis. so I have removed the following ApacheDS JARS from the classpath

• xml-apis-2.0.2
• xpp3-1.1.4c
