OAM 11g: Error while importing Custom Authentication Plug-in.

Question

We are trying to create a sample custom authentication plugin in OAM 11g as per the 11.1.1.5.0 doc.
But while trying to import the plugin via oamconsole (system configuration->Plugins->Import Plugin) we receive an error "Invalid XML Structure".
Do we have to embed the XSD (XML Schema Definition) as well ?

Answer 1

I build the Plugin.jar file similarly as above(followed the same steps)..
But when i log into OAM and trying to import the plugin (System Configuration->Plugins- Import Plugin) the browser goes to hung state and i see below error in logs (domain log and in diag log)
I see the jar file created in this location (\Middleware\user_projects\domains\IAMdomain\oam\plugins)
Please let me know if you have any idea..Thanks!
