    I am loading all the files in the file object and iterating one by one. I am getting the memmory issue.

    Default Re: Java heap memory error

    Either increase the amount of memory allocated to the heap via the JVM (see this), or ensure you read the minimal amount of data on each iteration and release all resources before proceeding with the next file. If you do not want to alter JVM settings and 1 file by itself is too large, use a SAX parser instead of a DOM parser (which I presume you're using) as SAX examines data while it parses where a DOM parser loads everything into memory before examining it.
