Hi,

If I build my war file and deploy it to JBoss using the following config file :

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC 
   "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory name="java:/hibernate/SessionFactory">
       
        <!-- How to use this ?   
        <property name="hibernate.jndi.class">org.jnp.interfaces.NamingContextFactory</property>
        <property name="hibernate.jndi.url">jnp://localhost:1099/</property>
        -->
          
        <!-- JNDI configuration for Sybase 
        -->
        <property name="hibernate.connection.datasource">java:SybaseDS</property>        
        <property name="hibernate.dialect">org.hibernate.dialect.SybaseDialect</property>

        <!-- Plugin ConnectionProvider --> 
        <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>

        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
        <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
        
        <property name="hibernate.transaction.flush_before_completion">true</property>
        <property name="hibernate.transaction.auto_close_session">true</property>
          
   <mapping resource="blahblahblah.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

I don't have any problem at all. The web app running correctly under JBoss.

My problem is, I have a test case, in which I would like to run using JUnit.
The following JUnit task does not work :

Code:

    <!-- Need to put junit.jar into $ANT_HOME/lib !!! -->
    <target name="junit" depends="clean ,prepare ,compile" description="Run the test suite">
        <mkdir dir="${test.out.dir}"/>
        <junit dir="${webinf.dir}/classes" printsummary="yes" jvm="java" fork="true" haltonfailure="yes" showoutput="true">
            <classpath refid="compile.classpath"/>
            <formatter type="plain"/>
            <formatter type="xml"/>
            <test name="example.test.AllTests" todir="${test.out.dir}" haltonfailure="no"/>
        </junit>
    </target>

because if I invoke Ant, I got this error :

[junit] 13:54:14,548 FATAL DatasourceConnectionProvider: Could not find datasource: java:SybaseDS
[junit] javax.naming.NoInitialContextException: Need to specify class name in environment or system property,
or as an applet parameter, or in an application resource file: java.naming.factory.initial

[junit] at org.hibernate.connection.DatasourceConnectionProvider.configure(DatasourceConnectionProvider.java:44)
[junit] at org.hibernate.connection.ConnectionProviderFactory.newConnectionProvider(ConnectionProviderFactory.java:80)

If I specify the JNDI Class&URL, so it becomes :

Code:

...
        <!-- How to use this ?   
        -->
        <property name="hibernate.jndi.class">org.jnp.interfaces.NamingContextFactory</property>
        <property name="hibernate.jndi.url">jnp://localhost:1099/</property>
...

I got different error :

[junit] 13:59:28,081 FATAL DatasourceConnectionProvider: Could not find datasource: java:SybaseDS
[junit] javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out]

[junit] at javax.naming.InitialContext.lookup(InitialContext.java:351)
[junit] at org.hibernate.connection.DatasourceConnectionProvider.configure(DatasourceConnectionProvider.java:44)

Anybody knows how to configure my hibernate.cfg.xml so I can run my test case ?

Thanks for any help/suggestions/pointers.

Thanks,
nusa.

Maybe your datasource is not visible outside jboss

Thanks for your input.

So that's why I had to specify the JNDI Class and URL, include jbossall-client.jar, and run JBoss. But the error still there.
I definetely miss something.

Any takers ?

Thanks,
nusa.

Datasources in JBoss are not available remotely, as it does not provide any sort of RMI-JDBC capability.

You'll probably need to utilize a direct JDBC access from your unit tests.

Steve,

Thanks for your suggestions.

OK, so if I have the following in my hibernate config for JBoss, it works :

Code:

    <!-- JBoss-JNDI version 
    -->
    <session-factory name="java:/hibernate/SessionFactory">
                  
        <!-- JNDI configuration for Sybase 
        -->
        <property name "hibernate.connection.datasource">java:SybaseDS</property>

        <property name="hibernate.dialect">org.hibernate.dialect.SybaseDialect</property>

        <!-- Common configuration --> 
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.use_outer_join">true</property>
        <property name="hibernate.order_updates">true</property>

        <!-- Plugin ConnectionProvider --> 
        <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>

        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
        <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
        
        <property name="hibernate.transaction.flush_before_completion">true</property>
        <property name="hibernate.transaction.auto_close_session">true</property>
          
        <mapping resource="abc.xml"/>

   </session-factory>

but if I want to use JUnit, I have to amend it to become ( it works as well ) :

Code:

    <session-factory>
          
        <property name="hibernate.connection.url">jdbc:jtds:sybase://server:port/tempdb;tds=5.0;lastupdatecount=true</property>
        <property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
        <property name="hibernate.connection.username">x</property>
        <property name="hibernate.connection.password">y</property>
        
        <property name="hibernate.dialect">org.hibernate.dialect.SybaseDialect</property>

        <!- - Common configuration - -> 
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.use_outer_join">true</property>
        <property name="hibernate.order_updates">true</property>

        <!- - Plugin ConnectionProvider - -> 
        <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>

        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
        
        <property name="hibernate.transaction.flush_before_completion">true</property>
        <property name="hibernate.transaction.auto_close_session">true</property>
          
        <mapping resource="abc.xml"/>

    </session-factory>

Instead of playing with the config file to commen / uncomment, depends on the need ( deploy or JUnit ), is there any other solution ?

Thanks,
nusa

You can try using a stand-alone transaction manager/datasource for your unti tests. Something like JOTM or Tyrex.

I would like to change our Hibernate conf to use a datasource from JNDI but I don't want to disturb the unit tests. I was glad to find this topic but disappointed that a solution was not found.

If anyone has an update please let me know.
