Running DB2 queries fails with: SQL0104

Hi folks,

Running several queries for DB2 is failing with the following error:
Error getting response; com.ibm.db2.jcc.a.rm: DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601 DRIVER=4.0.100

The following query is running successfully:
INSERT INTO Table(NAME) select 'test1' from sysibm.sysdummy1 where NOT exists (select * from Table where NAME='test1')

But when running 2 queries with ; delimiter then I get the error:
INSERT INTO Table(NAME) select 'test1' from sysibm.sysdummy1 where NOT exists (select * from Table where NAME='test1');
INSERT INTO Table(NAME) select 'test1' from sysibm.sysdummy1 where NOT exists (select * from Table where NAME='test1');

I tried to change the delimiter to : / , ! space and nothing worked.
The same quires run perfectly in the DB2 client, so it's the soapUI that is responsible for this.

Please assist.
