Java and Sybase nested stored procedures

I have nested Sybase stored procedures, the main procedure calls a helper stored proc.
The main procedure returns 2 result sets before calling the helper store proc and helper store proc returns 1 resultset. After the helper store proc is called, the main store proc returns 2 more resultset. When I run it using SQL client tool the main procedure(and it's helper) execute well and returns rows.

I need to call this store proc in a java code and display all the resultset in screen. I am using Statement:execute(<exec sp> to execute the store proc and then statement.getResultSet() to get each resultset. The loop is controlled by statement.getMoreResults() .

It displays the first 2 resultsets from main Store Proc. Then the control goes to helper store proc. It executes the helper store proc and displays the resultset from helper. But then it stops there and doesnot
come back to main store proc to execute the remaining resultset.

What I suspect is that, the statement object is getting overlaid when the call goes to helper proc. May be that Statement object maintains an internal list for Resultset and that list is over-written when helper proc is executed.

Any idea as to how to code to handle multiple nested resultset ?

My Sybase stored procedure code looks like -
create procedure main_proc

select getdate()
select @@servername

exec proc2

select myCol1, myCol2, myCol3
from mytable
select db_name()


Sybase Code for proc2

create procedure proc2
select @@version

EXEC sp_procxmode 'dbo.proc2,'unchained'

Code snippet :-
do {
int iit=0;
if ( rs != null ) {
ResultSetMetaData rsd = rs.getMetaData();
int nocols = rsd.getColumnCount();
for (int i=1; i<=nocols; i++)
while (rs.next())
for (int i=1; i<=nocols; i++)
} while (stmt.getMoreResults());
