DBCP borrowObject failed

[Axel Stahlhut]

Hi.
I'm having a problem with the Commons-Pool. Using Struts NightlyBuild from
2002-11-11, I have a DataSource configured in my struts-config:

 <data-source type="org.apache.commons.dbcp.BasicDataSource"
               key="org.apache.struts.action.DATA_SOURCE">
   <set-property property="defaultAutoCommit"
                 value="false"/>
   <set-property property="defaultReadOnly "
                 value="false"/>
   <set-property property="driverClassName"
                 value="org.gjt.mm.mysql.Driver"/>
   <set-property property="maxActive"
                 value="20"/>
   <set-property property="maxIdle "
                 value="10"/>
   <set-property property="password"
                 value=""/>
   <set-property property="url"

value="jdbc:mysql://localhost:3306/videodb?autoReconnect=true"/>
   <set-property property="username"
                 value="xxx"/>
  </data-source>

I am able to access 3 times, update a result set. After that I get the
following exception:

java.lang.NullPointerException
   at com.mysql.jdbc.Connection.execSQL(Unknown Source)
   at com.mysql.jdbc.Connection.execSQL(Unknown Source)
   at com.mysql.jdbc.Connection.setAutoCommit(Unknown Source)

   at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(Unknown
Source)
   at
org.apache.commons.dbcp.AbandonedObjectPool.borrowObject(AbandonedObjectPool
.java:117)
...

On the commandline i have the following output: DBCP borrowObject failed
Does anybody know, what is happening? Any help is appreciated.
