Patch 4 Problem - Missing irj folder

Hi,

I have started installing EP6SP2 Patch 4. As per instruction, I was supposed to stop IRJ service in SAP J2ee engine services>deploy>servlet_jsp-->irj. After doing that I went ahead with installation and I got an error message "The execution of Stop/Start IRJ terminated with errors. The return code was 1".

I went and looked into SAP J2EE Engine and I'm surprised to note that there is no IRJ service and as well irj folder is also missing in the file structure. Does anyone have come across this. Kindly let me know what I should do to restore my portal as it not working now.

Regards,

Praveen
