First, suppose you have the following Eclipse source file sample.pl

===================== sample.pl ===========================
:-open("sample.out",write,Stream),
  write(Stream,"Hello you. I'm running Eclipse !"),
  nl(Stream),
  close(Stream),
  halt.
===========================================================

and the following Java source file RunEclipse.java

======================= RunEclipse.java ===================
class RunEclipse{
  /*
    version     : jdk1.1.1 on Linux
    call syntax : java RunEclipse "command"
    effect      : execute the given command
   */
  
  public static void main(String arg[]) {
    Runtime R;
    R=java.lang.Runtime.getRuntime();
    try {
      R.exec(arg[0]);
    }
    catch (java.io.IOException E) {
      System.out.println(E);
    }
  }
}
===========================================================

You compile the java source file and obtain RunEclipse.class

Then, running 

    java RunEclipse "eclipse -b sample.pl"

executes the goal in sample.pl and produces the output file sample.out

Obviously, your java program can make a lot of things before and after the call
of Eclipse, but I think that the great lines are in these exemples. 
For further details in Java you have to look in class java.lang.Runtime 

Last thing : I have tried this example on Linux with jdk1.1.1 and Eclipse 3.5.2

Good luck :-)
