I have to test the speed after loading the .gz file in browser and I am having java applet based web application(Hello word) whose HelloWorld.jar file size is 743byets and using pack200 tool compressed to .gz(321 bytes)files.

1) created HelloWorld.java file

Code:




Created HelloWorld123.jar file with this class


2)Main html file hello.html
HTML Code:





3)First time tried to load the class file from the jar file it works fine(HelloWorld.class is loading in the browser).

HTML Code:




4) created different .gz file with same jar file(pack200 tool).

HelloWorld123.gz
pack200 --gzip -E9 HelloWorld123.gz HelloWorld123.jar

HelloWorld123.jar.pack
pack200 --no-gzip -E9 HelloWorld123.jar.pack HelloWorld123.jar

HelloWorld123.jar.pack.gz
pack200 --gzip -E9 HelloWorld123.jar.pack.gz HelloWorld123.jar


and tried these files with the above html code

HTML Code:




or

HTML Code:




or

HTML Code:






while loading this class I found that class loader error on sun console(as follows).
Code:




In the About detail I can get that HelloWorld123.pack.gz or HelloWorld123.jar.gz or HelloWorld123.jar.pack.gz is downloading.

My question is will browser decompress the .gz file to .jar file internally ? or I am missing some coding for .gz file decompression ?.
