Weblogic 8.1.3 Custom Identity Asserter

hi all,

currently I am trying to implement Custom IA on Weblogic 8.1.3 using modified codes which were originally for 9.2

I am getting a ClassNotFound error even though the class file is there.

Currently, the auto generated MBI java file contains a

instead of package examples.security.providers.identityassertion.simple (which i believe is the correct value)

Any idea how bypass this error ?

Triggering ./ant will give the following :
Buildfile: build.xml

[java] Working directory ignored when same JVM is used.

Any help is greatly appreciated.

A post in a particular website mentioned that I should run the DMDF twice.

Once to generate the class file and hit the ClassNotFoundError.

2nd time after copying the class files to some directories.

Anyone can enlighten me which paths I should copy the files to ?

Tried a few places but no luck.


java -DMDF=3D.\com\my\security\MyAuthenticator.xml -Dfiles=3D.\com\my\secur=
ity\ -DcreateStubs=3Dfalse -cp %CP% weblogic.management.commo.WebLogicMBean=

copy .\com\my\security\com\my\security\*.class .\com\my\security
copy .\com\my\security\*.class .

java -DMDF=3D.\com\my\security\MyAuthenticator.xml -Dfiles=3D.\com\my\secur=
ity\ -DcreateStubs=3Dfalse -cp %CP% weblogic.management.commo.WebLogicMBean=
