you're loading same class twice , 2 different versions. might have 2 versions of:
org/apache/http/params/httpparams check application loading , weblogic supplies. can either remove duplicate class/jar like:
java.lang.linkageerror error in class loading
or can use preferred classes in weblogic explicitly state version of class use (likely 1 packaged in application). see:
netbeans taking jsf server library instead of registered libraries
