Error while extracting data from SAP BW using SAP JCO in java

Hi All ,

I am using SAP JCO (SAP Java Connector)for extracting data from SAP system in java. But for tables which contains

large data it's throwing error "Exception in thread "main" java.lang.OutOfMemoryError: Java heap space".

Data till limit 61000 it's not throwing any error but after this limit it's throwing error.

I need to get the whole data from table.

Is there any way to do it?

Can we get data in batch using SAP JCO ? If yes then how?

Please help.
