Hello,
I'm sorry about my previous question with regards to the 500 internal server
error, I have already fixed to problem - I wasn't able to jar my classes
properly..
I have followed Sebastien's suggestion. But, still, it generates a broken
pipe and an out of memory exception. =(
For additional information, here's my service's code. Please help me.
public Vector returnVector ()
{
Vector v = new Vector ();
for (int i=0; i < 1000000; i++)
{
v.add("Vector");
}
System.out.println ("Done processing 1 million vector elements");
return v;
}
Thanks.
