what is the error you are getting ? make sure ur datasource is loaded.
You have to override as per the docs + u will need to append the prefix for your database in the configuration, if any.

maybe this with the mock objects will reproduce it for you.

thanks

I was essentially creating wrappers around actual services i wanted to invoke to achieve pretty much the same thing.
If i understand your approach, I could use my wrappers to implement this...

no. even if i create just a new config file and just place the above code , sts complains with the following.

After reading the a little more carefully.
I changed my channels from direct to queue channels. and it works as my requirement was quite different from what was obviously stated in the documentation...

from the xsd

Hi
I have attached a sample project (maven) explaining my problem. it also has the script for postgres.
The config file is as described below
The poller polls rTable and updates a column.
After...

coming to the original problem and your suggestion i tried ; my poller does work as requested.

The service activators are Services which do some business logic and update the state of a table...

This somehow worked. I will go back to addressing the original problem.

There is a problem with the update statement but the poller does not generate any errormessage. But i had this working yesteday, the only difference is i have created a fresh development environment....

i was trying at my end with different configurations.
but the poller just stopped working even in a standalone scenario.
but this has nothing to do with transactions for now though i would guess....

Thanks,

i tried this config




<int-jdbc:inbound-channel-adapter channel="tablePoller"
query="select * from table1 where column1 = 'value1' and column2 = 'value2' "...
