Rechard,
I suppose Eric wanna output HTML.
I myself prefer css to font tags. Introducing an XSLT engine is a nice
idea, however, it seems not the choice of Eric.
I suppose the current problem results from default configuration of
JVM or large numbers of substring with a big string.

Well, would you please post code relative to the variable of postions?

Well, to replace each 'create' with 'create',
you can leverage:
String origin = ...
String result = origin.replaceAll("create","create");
I am not sure whether this operation should result in the same problem.

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.

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.

Well, you use tomcat, right?
There is bin/catalina.bat, where you can specify -XX options.

Well, heap size and each division has its default value. In fact, they
are specified proper values, such as minimal size, maximal size,
ratio, etc., according to requirement. Did you try customizing memory
model of Hotspot at application startup? I suppose your problem can be
solved by increase the

$ java -version

"xxx" is regard as permniant object. does your StringBuilder leverages
sb.append("xxx")?
If so, I suppose it is the same to String
Well, It's -XX:MaxPermSize option rather than some -X option; you can
refer to this link for more information:

Well, I suppose I can offer some tip that may help.
Let me suppose you use Hotspot VM.
Sun's Hotspot VM 's heap space consists of three divisions for young
generation, old generation and perminant generation. Young generation
refers to objects that are created and usually it died in a short
time.
Well, I make multiple selection and submit the page, which will be
forwarded to if validation is not passed. I want to keep selected the
multiple s of when I am back. What can I do?
This is the fragment of source code:
Thanks in advance.
