I just noticed that my code doesnt work for files with DURSME_1.xml.zip extension,however if the file has the extension DURSME_1.zip the code works fine.

Is there any workaround for this?I need the code to work for files with the extension .xml.gz,.xml.zip,.zip

Please can some help with this?


Many Thanks in advance!

I don't see anything in your code that would care about what extension your files have. The only way you could get null in zipFile is if there is an exception thrown. I suggest printing out a stack trace in your catch block. It's generally not a good idea to have empty catch blocks. Either handle the exception or log it in some way (or both).

Also, I suggest using "/" as the file separator. It works on every operating system I've tried (including Windows), and has the added advantage of not being so ugly. To be truly cross-platform, you really should query the system properties for the file separator, but in practice "/" always works anyway.
 
I agree. Here's the link: http://aspose.com/file-tools
