Error when trying to open the MDM destinations page

[Former Member]

Hello,

We are trying to access the MDM destinations page in the SAP portal (at http://<host>:<port>/mdm/destinations/). We get the login screen correctly. However, after entering our credentials and submitting, we get the following error:

java.lang.NullPointerException: while trying to invoke the method java.security.KeyStore.aliases() of an object loaded from local variable 'keyStore'

We've checked with our basis team, and they have confirmed us that they have installed the following SCAs in the portal server:

- MDMCONNECTOR09_5-20007987.SCA - MDM 7.1 SP09 Patch5 - CONNECTOR 7.1 7.11

- MDMJ71009_284-10006189.SCA - MDM 7.1 SP09 Patch284 - Java API

They have tried re-installing both SCAs, and restarting the server, but we keep getting the same error.

We are on EP 7.31, and MDM 7.1

The full error is at the end of this post.

Does anyone know what could be causing this problem?

Thanks and regards!

Hi Alain,

Check the Note 1792307 - Exception error in MDM Destination Administration Tool

That should help you to resolve the issue.
