I am using latest version of ikvm.net , i have written a encryption/decryption class program in java.

I have compiled and build dll using ikvmc, i have included dll into my .NET project. I am calling dodecrypt function in .NET it is giving an error saying that...

"An exception of type 'java.lang.IllegalStateException' occurred in IKVM.GNU.Classpath.DLL but was not handled in user code"
"Additional information: must configure ecryption key first."

why this error is coming?.
any help is appriciable...

Thanks,
Prasad.
