Hi

I am getting this error while commiting transaction. My hibernate version is 3.0.5.

I can't move to any next version bcoz of issue of backward compatiablity.

Any help/suggestion would be highly appriciated. If it is bug & there is no fix in this version, only then i can move to next version but that has a big cost to me.

Hello Everybody

If someone needs some more details then i can send the same.
Please help !!!!

Hi,

you need to post

- mapping file
- hibernate code
- sql-output (show_sql=true)

Hi

I have more than 250 hbm.xml. and this case is not reproducable (we don't have steps to re-produce this). At any point of time, this exception comes but don't re-produce each time. Also our hibernate code is very distributed so it's not possible to mail all the code.

Regards

Ganesh Bansal

It is very rare that you use 250 hbm at the same time in the moment where the problem happens.

Read the stacktrace and find out which mapping and which source code is called. e.g. DataModel.getLinks(DataModel.java:1931)

Create a simple test case to reproduce the problem.
