user for java mapping in SAP PI

[vbalko-claimate]

Hello,

I have a java mapping in my PI/PO integration scenario, which access java keystore for certificates for signing the message.

I have a problem, that this mapping is run at runtime with the user guest, which does not have a access rights to the keystore.

I can think of 2 ways how to resolve this, but also 2 questions:

1. Change the guest user in runtime and put the authorizations for accessing keystore - how to do that?
2. add authorizations to the guest
3. Which authorizations ensures, that user can access keystore ?

Now I have added sap_all to the guest - which allows it to access keystore, but surely is not a good idea to the production.

Can you please help me with this?

Thanks

Vlado
