Re: Please help..



Yes, the proxy class exists. Earlier
I used to get this error if I don't have the
Proxy class.

Is this error dut to change in jre ?
Because earlier we had only jdk1.2.
Now we have installed jdk1.3 also
on our server and even IBM jikes.
But my PATH variables points
to jdk1.2. i.e when I execute "java -version"
it;s jdk1.2.2. But I suspect ozone might be taking
some other jre ( may be jikes ? ) internally.

Did u have any problem due to the change in jre ?

regards ,
Mahesh
