regarding j-link using servlets.

Hai
i have one doubt while working with j-link using servlets,
i am using asynchronous mode,where pro/engineer has started by my java
application.i had use one the sample codes in
\jlink\jlink_appls\install_test in this directory,it just start the
pro/engineer from my java program,it will work nice when i run in
command mode.using java <programname> proe2001.bat
but when i try to move the code to servlets,and in frontend i just
create one button,after clicking this,i want the pro/engineer gets
started and open the specifed model.but it won;t get started insted it
will give error like
UNSATISFIED LINK ERROR -AsyncConnection_Start

i am using jdk1.3,pro/engineer2001. and tomcat 4.1 webserver,
any help greatly appreciated!!!!
