How to overcome JSON string exceeds heap size limit error

Hi Guys,
When i click on custom button it will generate zipfile with attachments which i selected records. Everthing was fine but, if i try more than 4.3 MB it was throwing an error message. Here i used 2 Apex classes not used any visualforce page. I think the problem for apex class as of i queried the body from attachments. If we reduce the body length, may it come.I have been working on this issue for so many days. Could you please solve this issue.

Thanks,
Gopi.

Salesforce heap limits are heap limits.  If your use case allows, you could go to Future/Batch APEX which increases the heap limit to 12MB instead of the 6MB you're seeing now.  Keep in mind your heap is all memory allocated by the entire execution path, not just the JSON you're assembling.

Hi, In this scenario i used 1 Webservice Class and 1 normal apex class. In webservice class, i wrote return valueswhich are passed to one method which was in same class. From that method return the values to another class. @Future doesn't allow return. Thanks,Gopi.
