How to zip and unzip xml files dynamically by XI

Dear All ,

I am having <b>IDOC-XI-FILE</b> and <b>FILE-XI-IDOC</b> scenario and the output file or the input file is a .xml file .

<b>The xmls generated by XI(in case of Outbound scenario) or xmls taken by XI(in case of Inbound scenario) are to be ZIPPED in .zip files Dynamically Storewise .

We have to DYNAMICALLY GENERATE the zipped files as per the following convention : <Storecode>_<CurrentBusinessDay>_Filename.zip</b>

Note : I am able to generate files dynamically but generating zipped files dynamically is not known to me . Plz help . Also how to unzip Inbound xml files .

Thanks & Regards
