Apache Connection Pooling for Hibernate

N

Narsing

Guys,

Do anyone of U have a solution for this???

When I try to use the connection pooling of Apache for Hibernate, I get
Class not found exception. I did add the commons-dbcp-1.2.1-jar file to
the class path and added other properties in the config file ...
hibernate.cfg.xml ...
<property
name="hibernate.connection.provider_class">org.hibernate.connection.DBCPConnectionProvider
</property>

<property name="hibernate.dbcp.maxActive">8</property>
<property name="hibernate.dbcp.maxIdle">8</property>
<property name="hibernate.dbcp.maxWait">100</property>
<property name="hibernate.dbcp.whenExhaustedAction">1</property>
<property name="hibernate.dbcp.testOnBorrow">true</property>
<property name="hibernate.dbcp.test OnReturn">true</property>
<property name="hibernate.dbcp.ps.maxActive">8</property>
<property name="hibernate.dbcp.ps.maxIdle">8</property>
<property name="hibernate.dbcp.ps.maxWait">1000*60*30</property>
<property name="hibernate.dbcp.ps.whenExhaustedAction">1</property>






but I am getting the following errors:
