I followed all the steps mentioned in the article. I also saw the message - Added certificate to keystore ...

We are having an web based application whihc runs on JBOSS. But this application is still giving the same error - SSLHandshakeException

Do we need to chnage any startup parameters in the JBOSS script?

I tried to compile the java file to install a cert and I get a compilation error on line 152... I think it has to do with the inheritance using the : the way it is written out. perhaps this is a java version error... I am trying to compile with javac in j2sdk1.4.2_16

need help :(

if i run this application (anyway if in eclipse or by commandline) all seems to be fine. it tells me that the alias is added to jssecacerts.

but it aint. if i run the programm again it adds the certificate again to jssecacerts. and again, and again...
of course my java applications are still not able to handshake with the ca's host.

to you have an idea what could cause this problem?

So, you copied the article, and the original (together with its whole blog) is now gone away. Sadly, also the download links are now gone away. Do you randomly have copies of those?
