Speeding up launch of programs

Question

I am unsing Java_1.3.0 on a windows 2000 platform, and when I run the windows API command
ShellExecuteEx(SHELEXECUTEINFO info); with
the SHELEXECUTEINFO set up to run the program
javaw -jar jarfile.jar <param>
where jarfile.jar is about 30K.
The application takes about 20 seconds to load and run.
Is there anyway of speeding this up? Cacheing the JRE for example ??

Answer 1

It takes just as long using the command line as it does launching it from the program - ShellExecuteEx function works fine.
I have not trued windows NT, but in Windows 98 it takes a similar ammount of time.
How long should a launch take?
Is it dependant on what classes are used?
I am using mostly AWT only, but I do use Borland XYLayout classes. The full import list is:
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import borland.jbcl.layout.*;
import borland.jbcl.control.*;
import java.io.*;
import java.net.*;
import java.lang.reflect.*;
import java.util.*;
import java.text.*;
