How can i use this java program to access from a jsp page?

Question

}here i need to generate the strings like 'enter value1' and respective text boxes dynamically . i should use this java program as business logic and a jsp page for view.
following given is my text file input.eqn
input:enter value1:arg1
input:enter value2:arg2
input:enter value3:arg3
constant:enter constant1:arg4
constant:enter constant2:arg5
equation:enter equation:(arg1+arg2)*(arg3+arg4)*arg5
result:

Why do you double post ? http://forum.java.sun.com/thread.jspa?threadID=646988&tstart=0
Why dint that answer satisfy you ? And why dint you say so in that thread rather than posting the same question again ?
