Hi Viral,

That’s strange my ext-all.js is not compressed at all.

Above is the connector settings I have on server.xml. Thank you very much for you help.

@Agus: There is no upper limit on size for compression. Check the mime type that you have specified in server.xml. Is it application/x-javascript? Also try to refresh and clear cache to see if the browser is not serving the js from cache.

Hi Viral,

I have turned On the compression on my tomcat server. Below is the setting of my server.xml

And it works on all js files, except ext-all.js file which is around ~650KB, and this file is my main intention of of turning ON the compression. Is there any upper limit on the size of the file to be compressed?

Hi,

Thanks in advance.

I am using WAS5.1 and J2EE 1.4.
I want to use GZip compression in my Struts application.
I am able to use this compression for .jsp and .html file.
Once I configure GZip compression for (/*) patten, it gives below exception.

I am able to used GZip compression for struts application in Tomcat environment, but it does not work for Struts action in WAS5.1.

Where can I find info on how a client can UNCOMPRESS this data? All these articles/topics assume the server is hit from a browser. The browser handles uncompressing the data automatically. I’m not hitting my server from a browser. I’m using another client program.

@rasha, @choesang: Generally the problem that you are facing is due to browser cache issue. Clear your browser cache and try again.
