Ojb and LDAP/JNDI

All,

 

I didn't' find the solution in the Archive. Here is my trouble. 

 

I want to externalise in a LDAP/JNDI all my databases connections. I know
that I can do that with the DataSources objects. I put the
"jndi-datasource-name > in the repository-database.xml.

 

 

But what I don't know is how to use it. Can someone send to me some piece of
code.

 

I have tried with the classic code .

 

And I have this error :

[org.apache.ojb.broker.accesslayer.ConnectionFactoryAbstractImpl] ERROR:
Naming Exception while looking up DataSource (java:comp/env/jdbc/ds1)

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

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

      at

      at
javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:243)

      at
javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:280)

 

 

What does that mean?

 

Thanx !

Hi,

seems that OJB could not get JNDI-Context.

I'm not an expert (means, I don't really know), but
maybe you have to set implementation specific JNDI-properties.
To do so use OJB class

NamingLocator.setContext(Properties properties)

method before lookup connections (e.g. at startup).

In the docs of your JNDI-provider you should
found the needed specifications

properties = new Properties();
prop.put("java.naming.factory.initial", fac);
prop.put("java.naming.provider.url", url);
prop.put("java.naming.factory.url.pkgs", pkgs);
... some more

HTH

regards,
Armin

Hi,
if you use java:comp/env.... then you have to setup your local
context. If you know where the datasource is located in the Jndi
, normal under jdbc/ds1, then use this name direct.

If you are in an web container then you must define a reference in
The web.xml file as follow:
  <resource-ref id="ResourceRef_1053550116384">
  	<res-ref-name>jdbc/ds1</res-ref-name>
  	<res-type>javax.sql.DataSource</res-type>
  	<res-auth>CONTAINER</res-auth>
  </resource-ref>
If you deploy the application to your application server, then you must
Enter the real position of ds1 in your jndi service.

Regards 
Matthias
