Urgent please.

Can any one tell me, what i have to do if the String Object holds data more than 20-22MB of data.
The string object holds that much of data and then the same data have to be displayed in a text area.
i am doing something like this:
private void doReadFile(BufferedReader fileReader) {
String strial = "";
String s = "";
try{
if(fileReader != null)
{
ivjTextArea1.append("One Moment Please.....");
while ((s=fileReader.readLine()) != null)
{
temptrial.append(s+"\n");
}
strial = temptrial.toString();
ivjTextArea1.setText(temptrial.toString());
fileReader.close();
}
} catch(Throwable exception){
handleException(exception);
}
}

I have mentioned the full path :
Runtime R = Runtime.getRuntime();

R.exec("d:\\ActivePerl\\bin\\perl rscdetail2.pl " + contract_number+" "+member_id+" "+start_date+" "+end_date);
I used Visual age Debugger and checked the value it generates from this -- "d:\\ActivePerl\\bin\\perl rscdetail2.pl "+ contract_number+" "+member_id+" "+start_date+" "+end_date
i guess its generating a correct path to look up for rscdetail2.pl but for some reason it's not understanding R.exec() ???
Does it have to do anything with Active perl for windows platform.

i am new to perl world, so can u please elaborate on that.
I am using Visual Age for java and Active Perl for windows platform.

I have a stand alone application which take the inputs from the user. i have a perl program which works fine on its own.
But is there any way where i can take the inputs from that stand alone java application and pass the inputs to this perl program to do some processing?

i have two drop down menus. one is the parent menu and the other is a child drop
down menu.
the child drop down menu listing should change whenver the parent entry change.
To make thing more clear-
Eg;
suppose parent drop down menu has two listing:
Hardware
Software
and child drop down menu has following thigs:
Hard disk
VB
Memory
Oracle
so whenever users selects --Hardware-- from the parent menu
childmenu shld have only two things in it
Hard disk and Memory
how can u have this kind of functionality in awt.(plain java)
