Com.wm.lang.flow.FlowException null connection returned from connect call

Using EAI version 4.6 with the following patches in place:
IS_4-6_SP2, IS_4-6_SP2_Fix150, IS_4-6_Fix48, IS_4-6_FIX_23

I am getting the following Null Connection Error:
com.wm.lang.flow.FlowException:null connection returned from connect call

Does anyone know what the fix is?

Here are some inf on my setup.
DB URL: jdbc:oracle:thin:@x.x.x.x:port:dbname
DB Driver: oracle.jdbc.driver.OracleDriver
Min Conn: 0
Max Conn: 200
Exp Time: 60000 (ms)
Loaded Driver: oracle.jdbc.driver.OracleDriver

Hello,
I have a service which runs the entire steps without any errors and then goes to the catch block giving an Exception error.
wm.lang.flow.FlowException.

Iam getting the output i want, but its giving me the EXception.
Could someone plz tell me the reason why after doing everything right its givng me an Exception.

Iam not getting any idea about what the problem could be

Thankyou.

Hi Stepheny,
Check your try-catch sequence.

is it like:

Main Sequence(Exit on Success)
----Try Sequence(Exit on Error)
------- code1
------- code1
----Catch Sequence(Exit on Done)
------- getLastError
------- handleExceptionCode3

if not, make it like this.

Other point to trace is, when tracing in your try block code, do you encounter Exit with Failure?

Hi Hares,
Can you open a SQL Plus connection to the Oracle DB and make sure that your DB username and passwords are correct?

Also, go to the IS Admin page and click on About and check that classes12.zip is loaded in IS.

Hai Singh,
Thankyou so much for your instant reply…

My sequence is like this…Same as what u said …but No ERROR but have FAILURE.

Main Sequence(Exit on Success)
----Try Sequence(Exit on Failure) Not ERROR…i dont find any ERROR
------- code1
------- code1
----Catch Sequence(Exit on Done)
------- getLastError
------- handleExceptionCode3

Is this what u meant ??
Its like this…
Plz letme know whether this is right or not…
