I searched my jar files and did not find anything having "bundle" in the
name. The persistence managers I have are:
DatabasePersistencemanager.class
DerbyPersistencemanager.class
JNDIDatabasePersistencemanager.class
OraclePersistencemanager.class
SimpleDBPersistencemanager.class
How do I change this to a bundle persistence manager? In my
StartServer.class, I have the following code:
// Register the repository in JNDI
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.jackrabbit.core.jndi.provider.DummyInitialContextFactory");
env.put(Context.PROVIDER_URL, "localhost");
InitialContext ctx = new InitialContext(env);
RegistryHelper.registerRepository(ctx,
"repo",
configFile,
repHomeDir,
true);
My classpath contains:
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con"
path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="var" path="WAS_EXTDIR/log4j-1.2.13.jar"/>
<classpathentry kind="var"
path="WAS_EXTDIR/jackrabbit-jcr-rmi-1.2.3.jar"/>
<classpathentry kind="var" path="WAS_EXTDIR/jcr-1.0.jar"/>
<classpathentry kind="var" path="WAS_EXTDIR/slf4j-log4j12-1.0.jar"/>
<classpathentry kind="var" path="WAS_EXTDIR/concurrent-1.3.4.jar"/>
<classpathentry kind="var" path="WAS_EXTDIR/jackrabbit-core-1.1.1.jar"/>
<classpathentry kind="var"
path="WAS_EXTDIR/jackrabbit-jcr-commons-1.2.3.jar"/>
<classpathentry kind="var" path="WAS_EXTDIR/jackrabbit-api-1.2.3.jar"/>
<classpathentry kind="var" path="WAS_EXTDIR/lucene-1.4.3.jar"/>
<classpathentry kind="output" path="bin"/>
</classpath>
My repository.xml has:
<PersistenceManager
class="org.apache.jackrabbit.core.state.db.SimpleDbPersistenceManager">
<param name="driver" value="com.ibm.as400.access.AS400JDBCDriver" />
<param name="url"
value="jdbc:as400://ISERIES/MYSCHEMA;
errors=basic;
trace=false;
thread used=false;
naming=system;
libraries=*LIBL,wbtstdta,wbtstexc"/>
/>
<param name="user" value="xxxxxx" />
<param name="password" value="xxxxxx" />
<param name="schema" value="db2"/>
<param name="schemaObjectPrefix" value="PEP_"/>
<param name="externalBLOBs" value="false" />
</PersistenceManager>
Do I need another jar?
Thank you,
