[JBoss-user] passivation exception

[Shawn C. <sha...@pt...>]

Hi,

I am getting a NotSerializableException during scheduled EJB passivation
attempt. I have a EJB that does a simple query. I am using Informix-SE and
Informix JDBC 2.20 drivers which implement the JDBCX.

Can anyone give me a direction to go in?

jboss.jcml:

<mbean code="org.jboss.jdbc.JdbcProvider"
name="DefaultDomain:service=JdbcProv
ider">
  <attribute name="Drivers">com.informix.jdbc.IfxDriver</attribute>
</mbean>

<mbean code="org.jboss.jdbc.XADataSourceLoader"
name="DefaultDomain:service=XADa
taSource,name=InformixDB">
 <attribute name="PoolName">InformixDB</attribute>
 <attribute
name="DataSourceClass">org.opentools.minerva.jdbc.xa.wrapper.XADataS
ourceImpl</attribute>
 <attribute
name="URL">jdbc:informix-sqli://10.5.0.5:1525//usr4/ptk:INFORMIXSERV
ER=tipper_se;user=xxxxx;password=xxxxx</attribute>
 <attribute name="JDBCUser">xxxxx</attribute>
 <attribute name="Password">xxxxx</attribute>
 <attribute name="MinSize">5</attribute>
 <attribute name="MaxSize">10</attribute>
</mbean>

EJB code that grabs a connection from the pool:

public void getConnection() throws Exception
  {
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY,
            "org.jnp.interfaces.NamingContextFactory");
    env.put(Context.PROVIDER_URL, "localhost:1099");
    env.put(Context.URL_PKG_PREFIXES,
            "org.jboss.naming:org.jnp.interfaces");

    dbConnection =
      ((DataSource)new InitialContext(env).lookup("java:/InformixDB"))
        .getConnection();

    }
