What is textFormat?
It isn't a StringBuilder is it?
textFormat.append(subText);

String subText = fullText.substring(start, posLetter);

subText = null; //not required
start = posLetter + 1;
}
with fullText = 5M and textFormat that's even bigger it crashes.
An friend tried with a 15M file using Lingo language and it worked without
problems and I bet .NET would have no problem either but I'll know tomorrow.

Sorry to hear that.
Would you please show some source code relative to the problem?
Well, 5000 loops of substring with a big string is terrible.
2005/11/29, Eric Plante <[EMAIL PROTECTED]>:
It wasn't there but I added it and whatever I used -Xmx or -XX, it didn't
work. I wrote 100m for the -XX...
I also checked again where I could optimized and where I could find memory
leakage. Reducing the number of string meant using StringBuilder's
insert....the slowness of that command makes it not an option. I couldn't
find any memory leakage.
Where the program systematicaly crash is a loop where I do a substring of
the big string everytime(about 5000 loops).I then fill a StringBuilder
which
will eventualy be bigger than the main string. That's the fastest way I
can
do what need to be done and it needs to be fast.
I'm starting to loose faith in Java...I'll ask a friend that
isa.NETspecialist to see if.NET has that problem too...a problem Java
shouldn't have...
-----------------------------------
I found in my catalina.bat:
set JAVA_OPTS=
Instead of that, use:
set JAVA_OPTS=-XX:MaxPermSize=10m
-Xmx512m seems only increase max size of heap rather than perm division.
2005/11/29, Eric Plante <[EMAIL PROTECTED]>:
I found the required catalina files and I see 4 lines with the JAVA_OPTS
variable. I tried replacing JAVA_OPTS and then %JAVA_OPTS% by -Xmx512m
in
the catalina.bat file but I still get the error message, what am I
suppose
to do in that file?
