compress a xml file

[srikanth Thandra]

hi everyone,

Can anyone help me on compressing a xml file.

Can we programatically compress a xml file in java.

[Ulf Dittmer]

Sure. XML is text, which should compress nicely using zip or gzip (both of which are implemented as part of the java.util.zip package). See http://www.exampledepot.com/egs/java.util.zip/pkg.html for some examples.

thankx for your suggestion, but i have another query..

For general text files comprerssing we use java.util.zip package.

But I want to compress a xml file which is sending as a file attachment.

Actually i am working on webservices.Client sends a request to my webservice in xml format file, i am attaching that file using SOAP and sending to the service.

So now what my question is can we compress that webservice request xml based file and then send it as an attachment.

It's no problem to send any file (compressed or not) through a WS. See Transferring files over a web service and Sending SOAP attachments using SAAJ.

thankx for your suggestions and replies.

I have referred to your given information and done successfully sending a request to the service as a attachment.

I have a query now.... After requesting i am able to generate a response for the given request. I am storing the response as a xml file in a particular location(i.e in file system).Now I want to send that response xml file to the client as an attachment.

But it is not working well. It doesn't even showing any exception like FileNotFoundException,unable to read the xml content.

I stucked here to proceed further. Do you have any code for sending the response as an attachment from the webservice to client.
