digital signature verfication using Java mapping

[Former Member]

Hi Experts,

We are getting the Class linkage error for the Java mapping developed to verify the digital signature. It seems that itu2019s not able to find the KeyStoreManager Class but I checked the mention class is present in server. Please let me know your inputs to resolve the issue.

Hi Alok,

While compiling the DigitalJavaMapping class have you imported the jar file containing com.sap.aii.security.lib.KeyStoreManager?

Also check what version of jdk is used in your PI server, you need to compile the java mapping with the same version

Hi Surag,

Yes, I have imported the jar file aii.security.lib which contains the com.sap.aii.security.lib.KeyStoreManager. I had already checked the jdk version used in PI server and the java mapping. Both are same 1.4.2.

Thanks,
