The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned for JNLP files SAP PI


Not able to open the esr part of the SAP PI 7.3, but I was able to open id(configuration part).

Present java version: build 1.8.0_131
After getting error, I have tried to update java also 
build 1.8.0_144

But still same error.

After spending 3 or 4 hours , discussion with other colleagues also not useful.
google searching and finding many solutions by others.
one solution helped to solve this problem  ;-)

Actually, java security file(related to MD5*, stopping to lanch this file.)
As suggested by google search solution:

I have opened the java security file( with admin rights) update the file.
Note: ( we are not supposed to modify this file in general). 

C:\Program Files (x86)\Java\jre1.8.0_144\lib\security  java security.
