Exception in thread "main" java.lang.InternalError: URLSeedGenerator file:/dev/random generated exce

Mudit Agarwal — Fri, 26 Sep 2003 18:18:08 GMT

I have java 1.4.1.02.00 installed on HPUX - B.11.11 U 9000/800.
When I try to access https url from a client it throws error 'Exception in thread "main" java.lang.InternalError: URLSeedGenerator file:/dev/random generated exception: Permission denied'.

Any idea what is wrong.

Thanks,
Mudit

Hi

Do you have a /dev/random file on your system ? If so what are the permissions on that file

Just a hunch

HTH

Thanks for the reply,
Yes, I do have the /dev/random device file and the permissions on it are 'cr--r--r--'.
And I don't think I have writes to change the permissions on this file. So is there any other work-around.
Thanks,
Mudit

It owuld be helpful if you add some context to this by sayin what webserver/appserver are you running.

Since you are accessing it by https: //
I would also look at the server logs to see what exactly happened.

As a workaround back up your /dev/random and link /dev/random ato /dev/urandom.Mind you this is just to isolate the problem.

If you see the above approach working something is wrong with jdk or the key tool generation code.

Hope this helps

I've run into the same issue using the 1.4.1.06 JRE. I was able to trace it back to the HP Secure Random Number Generator software packages installed. Uninstalling those packages allows java to function normally. Unfortunately, I haven't been able to find an answer as to why this occurs.
