Hi,
I have a class A and B. and B has a 1-1 relationship with A such that they have the following mapping:

<class name="B" table="B">
<id name="id" column="id">
<generator class="foreign">
<param name="property">Aref</param>
</generator>
</id>

<one-to-one name="Aref" class="A"
constrained="true" cascade="all"/>
</class>

<class name="A" table="A">
<id name="id" column="id">
<generator class="identity"/>
</id>
</class>

Now when I try to save B I expect that A will be saved too. But I get the following connection pooling error:



Is it that C3P0 library that has been recommended in Hiberbate docs is buggy?
are there any other alternatives?

Im using MS SQL Server 2000 and the JDBC driver is SQLServer 2000 Driver for JDBC
