BIRT & gzip problem? [message #646337] Thu, 23 December 2010 07:03 Go to next message
Eclipse UserFriend
Hello,

I continue my old discussion

http://www.eclipse.org/forums/index.php?t=msg&th=200471& amp;start=0&S=ae0a82523ba358e5ca8bd169eb4ad907

As Jason wrote the BIRT uses allways the iText setFullCompression method. I found out that for my big test material the winzip compress the BIRT pdf to the 5% size.

So I tried to use the GZIPOutputStream for my servlet. My servlet processed the gzip file, but I couldn't open the unzipped file with the Adobe reader.

So I wrote the simple java program, which runs simple BIRT report with the simple data. I run the program and used gunzip. I got the error message "There was an error opening this document. Access denied" when I tried to open the file with the Adobe reader. This error message sound like I don't have rights to open the file, but file is only read-only.

It is possible that this problem is not related on the BIRT, but is there some problem with my Java program?

Thanks,

Mika

Mika,

As a test can you use birt to write out the pdf and then open it with
your java program and try to gzip it and save to another file and then
try to open it with adobe?

Hello,

Above GzipRunReport.java is working fine. I used the winzip and result is ok. There was some problem with the gunzip.

But my custom BIRT servlet is not working with the gzip. I can't post the actual customer code to the forum.

The servlet passes the gzip stream like this to the BIRT:

options.setOutputStream(new GZIPOutputStream(httpServletResponse.getOutputStream()));


When I run the servlet there are not exceptions and special log messages. Only the white page opens to the browser. When I save with JUnit test the server response to the disk and try to extract the pdf from the gzip file I got the "Invalid Compressed Data -- unable to inflate." error message.

Do you see any reason why the servlet is not working?

I have another test servlet, which reads the pdf file from the disk and then returns the gzipped response. That is working fine.

BR,

Mika

Hello,

The problem solved!! I have to close the GZIPOutputStream. Normally I don't have to close the httpServletResponse.getOutputStream(), because the servlet container etc. creates and closes it.

Mika,

Very cool. I wish you would write this up and put it on birt exchange
dev share.

It is possible that I write later this to the birt exchange
dev share. Currently I'm too busy with project...

Sure. If you get time in the future this would be cool.
