profiling info - SIGQUIT dosen't work anymore in 1.3.1

In 1.2.2_0x, we had written a pipe to stdin of our servers and used kill
-3 to interact with VM to get the heap usage. Using this method we could get Heap, cpu and monitors information during the runtime. There is no way to do this in JVM 1.3.x.

How to get programatically the following information in JDK1.3.1?

1) Heap profiling Information
2) CPU usage
3)stack trace
4) monitor info

We would like to enable our servers in such a way that they periodically give us the above info.
