Hi,

I am developing a login module on java platform for SAP Portal application. The problem that I stuck is the system is generating "Cannot load login module class" error in "defaultTrace" log while loading the class. Please find detailed error, below;

#1.5 #000EA6143E4E007700000012000008F40004694D133B0722#1241679662875#com.sap.engine.services.security.authentication.logincontext#sap.com/irj#com.sap.engine.services.security.authentication.logincontext#Guest#0##n/a##d3cf4eb03ad411deaa44000ea6143e4e#SAPEngine_Application_Thread[impl:3]_13##0#0#Error##Java###Cannot load login module class {0}.

I created a class named "astronLoginModuleClass". Then created a library project, named "AstronLoginModuleLibrary" and attached login module jar (astronLoginModuleClass) into the project. At the end of this respective deployment, I created an entry under "Secure Store" with the parameters, below;

Class name: com.sap.astron.login.authentication.astronLoginModuleClass

Display Name: AstronLoginModule

Description: Astron login module

Then, I added this entry under "ticket" component on VA, named "AstronLoginModule". At the end of it, I restarted the j2ee server, but I faced with this problem. I can see jar application under "D:\usr\sap\PTO\JC00\j2ee\cluster\server0\bin\ext\com.sap.astron.login.authentication~AstronLoginModuleLibrary" and see this path under "Libraries".

Anyone has any suggestion about this problem?

Thank you

Hello Orkun,

I had a "Cannot load login module class" problem when I tried to develop my login module. I searched the SDN and found you had exactly the same issue.

I have completed the job to upload the loginmodule.jar as a library, configure the login module in Visual Administrator and the configure job on configtool. But I still cannot get it running.

Could you please let me know how I can solve my problem.

Best Regards

Jack

Hi,

Thank you for your response. As I indicated my question, I configured this value as "library:AstronLoginModuleLibrary" which is the library project that contains LoginModule jar file. I am waiting for your further suggestions.

Thank you

I forgot to say that I configured "library:AstronLoginModuleLibrary" on configtool, under "LoginModuleClassLoaders"
