NWA not working after patching NW 7.3 JAVA application server

Hi Experts,

After installing a new SAP 7.3, i patched it to stack 5 and as a result NWA and system administration no longer works, gives a 500 error, all other JAVA pages tested, user management etc all work.. MMC shows SAP is up and i can find no obvious errors.

I have checked a number of posts here but so far no help.
