Re: [Springframework-developer] How to do batch with Spring using Ibatis

I still canot get pass why the application hangs on this particular line:=
=
executor.executeBatch();
I know that executor is an Ibatis API, but is there anything else in Spri=
ng that needs to be configured to use it appropriately? Thanks.

Ok, my application is hung at the line :
executor.executeBatch();
Why would this happen?
=
I made a mistake, the transactions I mentioned was for something else. He=
re is what is really happening. I put a log statement just when entering =
and exiting the call to deleteFamily and here is where the application ha=
ngs (The browser is also hanging waiting for a response)
2004-07-31 14:43:50,841 DEBUG [com.ibm.method.web.manage.FamiliesAddUpdat=
eDelController] - <Entering deleteFamily(fbo)...........>
2004-07-31 14:43:50,841 DEBUG [java.sql.Connection] - <{conn-100135} Conn=
ection>
It appears it is not coming out of the deleteFamily method which now look=
s like this:
public void deleteFamily(final FamiliesBO fbo) throws DataAccessException=
{
getSqlMapClientTemplate().execute(new SqlMapClientCallback() {
public Object doInSqlMapClient(SqlMapExecutor executor) throws S=
QLException {
executor.startBatch();
executor.delete("AuthMaint.deleteCatExtendName", fbo.getMetho=
dElement());
Iterator itr =3D fbo.getRepItem().iterator();
while (itr.hasNext()) {
Map m =3D (HashMap) itr.next();
executor.delete("AuthMaint.deleteDocMap", m);
executor.delete("AuthMaint.deleteRepItem", m);
}
executor.delete("AuthMaint.deleteContentEdition", fbo.getMeth=
odElement());
executor.delete("AuthMaint.deleteMthElem", fbo.getMethodEleme=
nt());
executor.executeBatch();
=
return null;
}
});
}
Thanks Dmitriy! Actually I had done that and it fixed the problem. Now,
what I am noticing is that before using the batch all my statements woere=
done in one transaction, now using the executor, it appears that every
statement is now done in its own transaction. Why would this be the case?=
Stefan,
declare FamiliesBO argument as final i.e.
public void deleteFamily(final FamiliesBO fbo) throws
DataAccessException {...}
Regards,
Dmitriy.
