Subject: Re: [iText-questions] PDFReader - Exception inthread
"main"java.lang.OutOfMemoryError: Java heap space
Paulo,
Thanks for the guidence. Using the RandomAccessFileOrArray appears to
degrade
as it goes through the file. Is their any optimizations what I can
implement to
improve this?
Using the latest release should be a bit better but the trade-off here is
always memory for speed.
Another question, I moved the application to a Server class machine with
4-CPU's
and 4GB of memory. It doesn't seem that Java VM will allocate to a larger
size
other than 1024. Do you have any advice on this.
No idea.
Paulo
Thanks again for the quick response.
Bill
