Re: RE: using jt400 in a java applet

 
Hi All,

I am experiencing with java & permissions issue while accessing ERP through web where WebSphere services automatically. We found the below errors. Do u have any idea about below. I am really stuck up here. Frankly saying whether it is related java or permission, dont know. I am using WebSphere 6.0.2.29 on AS/400. ERP is running based on WebSphere. Please advise me on this issue. It will be really helpful.

Signing an applet is not that difficult, I just had to do it last week.
It does take a little while to read the jar-signing tutorial and a
longer while to read (and absorb) the documentation for the keytool
command, but I don't see it as a show-stopper for you.

I used a self-signed certificate, since my application was for internal
company use. Sounds like yours is too, so that's probably the way for
you to go. Unless your college has already paid up for one of the public
SSL certs.

My vendor is involved but the vendor has no knowledge of the jt400.jar I
am using and so I have been investigating from that angle to try and
prove or disprove something in that class might be the problem. Since my
error is about reflection and it appears that the jt400.jar is using
that the error is coming from the jt400.jar and not the vendors code.
I'm not real thrilled about needing to distribute a policy file to every
PC that needs to use the applet. That would be OK for college owned PCs
as we can push the policy file out but this applet could be used from an
employee on a home system on a vpn connection and I want to try and use
the tool to build applications that could be used by students also and I
will not be trying to have them modify a java policy file to make that
possible. I will go learn about how to sign an applet and see of that is
an option for me.

Thanks for the explination
