JSP Parsing error with JRun

Help!
I've got a large JSP with a significant amount of HTML in it (about 40 pages if I printed it out). Currently the page is only HTML- no JSP tags except for:
<@% page buffer="100kb"%>
What happens is that when I run the JSP through JRun/Apache, it displays part of the HTML correctly, then shows a fragment of HTML code(something like "<img src ="http://" and then breaks off), and nothing else.
I have tried various buffer sizes, but no matter what I change the buffer size to, the same thing happens. In fact, the exact same thing happens if I have no buffer set at all- it's as if it's ignoring my buffer. I have tried running the page with both Jrun 2.3 and 3.0. Any suggestions?

Check the jsp page with a hex editor like UltraEdit. I've seen a similar problem and it wound up being a couple of charaters that where A0 instead of 20(space character) If you view the page in an editor, the A0 shows up as white space and isn't obvious. You may have something like this in your file.


I Hope This Helps

Thanks for the suggestion. I just downloaded Ultra Edit and there are no "A0" characters instead of "20"s. One thing I did notice, however, is that every time there is a line break, there is both a "0A" (line feed) and a "0D" (carriage return). Could this have something to do with it? I am actually generating the JSP code via a Java program using the following I/O classes:
FileWriter fw= new FileWriter("Comparison_"+i+".jsp", false);
BufferedWriter bw= new BufferedWriter(fw, 100000);
PrintWriter pw= new PrintWriter(bw, false);
Then, using a series of pw.print() or pw.println() statements.

OK, I just found a solution on another board, and just thought I'd reply to my own topic for the benefit of anyone else reading this:
Jrun apparently has a problem with large chunks of HTML (my file was almost all static HTML for the moment). The solution is to intersperse the JSP with empty JSP tags such as:
<%=""%> . This will cause JRun to break the HTML into smaller chunks, and display the page correctly.
 
I agree. Here's the link: http://aspose.com/file-tools
