JSP page gives ArrayIndexOutOfBoundsException in websphere for z/os

[Sudhir]

Hi,
I have a jsp which list a number of records, it works perfectly
fine when i run on a NT machin using WSAD4.0.2 but when deployed on
Websphere 4.0.3 on z/os it gives a strange error. The stacktrace is
below. Can anyone tell me why this is happening and any possible
solutions to it? I am using struts too.

Error Code: 500

[stack trace tail removed]

Well, the API docs for String.getChars detail the conditions under which
an IndexOutOfBoundsException may occur; ArrayIndexOutOfBounds is an
IndexOutOfBoundsException, so its cause should be among those listed.
All the listed conditions are related to indices into the String or the
target array, which stands to reason given the exception class.

Without looking at the source for
jsp.chargeback.potential.viewPCBList.jsp it is impossible to pinpoint
the problem, but if you'll allow me to consult my crystal ball... let's
see... ah, ok. The infallible crystal ball tells me that your error is
related to differing default charsets in the two environments, not
specifying charsets explictly, and confusing byte counts with character
counts. There's also a corrupt Nigerian banker in your future.
