Runing java pogramfrom Servlet

Question

Hi everbody
I was trying to execute and run ajava program from servlet. It seems to me the servlet can compile the code but it is not capable to execute it. I have tried to save the class file in a bat file after the servlet compiled it but it did not work. any help will be appreciated.
try{
String[] command = {"javac","c:\\class\\test.java"};
Runtime rt = Runtime.getRuntime();
Process p = rt.exec(command);
catch(Exception ex){  }
try{
String[] command = {"java","c:\\class\\test"};
Runtime rt = Runtime.getRuntime();
Process p = rt.exec(command);
catch(Exception ex){ }

Hi !
I'm having the same problem. But in my case, it's an attempt to execute a Jini program (which I must execute with runtime flags, kind of -Dhostname=MyHost, etc).
However, I managed to execute a Java program without passing to it the runtime flags:
1. with Class.forName (ClassName)
2. with new ClassName
With Runtime.getRuntime ().exec () I get exitValue () equals to 1 (when 0 = OK). I don't really know what should be configured in Tomcat so that this works...
Hope this will be of any help to you.
