Hi All,

   I wrote a Java program to chunk and join files to overcome the 3MB limit of file transfer in Salesforce.

   Now the problem is .. how to run in the Sandbox env.

    Basically, I want to attach a file to contacts..but if the file is more than 3MB, I want to chunk it and attach 2 files...and while I download the file ....I will join it using the Java program on the server side.

   Please, post the code snippets if you have.

Thanks

Sanjeev
