Hi Bruno,

I have a few tips on this sort of Java error.

This error occurs because the voms-proxy-info command runs a java program which needs a library file (a jar) called bouncycastle. Bouncycastle is a set of SSL routines written for Java.

The error, java.lang.ClassNotFoundException: org.bouncycastle.openssl.PEMParser, indicates that the java system needs a class which is in bouncycastle, called "PEMParser".

(Perhaps the name "PEMParser" means it's the routine that reads a certificate file.)

Anyway, the java system can't find that class, so it blows up.

It's likely you have either a) no version of bouncycastle on your system, b) the wrong version of bouncycastle or c) some config error in the way bouncycastle is installed.

To help, here are the versions of bouncycastle on my system (which seems to work OK).

$ rpm -qa | grep bouncy
bouncycastle-mail-1.46-2.el6.noarch
bouncycastle-1.46-1.el6.noarch

$ rpm -qa | grep voms
voms-2.0.12-2.el6.x86_64
voms-api-java3-3.0.5-1.sl6.noarch
voms-2.0.12-2.el6.i686
voms-clients3-3.0.6-1.el6.noarch

Cheers,

Ste

I'm having some problems to check the information of a proxy in a SL 6.9 machine, whenever I try to run the voms-proxy-info command I get the following error. The installed package is

voms-clients3-3.0.7-1.el6.noarch

And the error I'm getting is

I've tried java 1.6, 1.7 and 1.8 but the result is the same. It's also worth to be noted that the command "grid-proxy-info" from the package "globus-proxy-utils-6.19-1.el6.x86_64" works perfectly.
