Re: Trouble with context and JNDI resource

[Carsten Pohl]

Hi,

I am no expert, but your lookup looks strange. (Empty string in lookup). 
Furthermore these two contextes seem "strange" to me.

This works great for me:
    @Override
    public void init() throws ServletException {
         LOGGER.info("INIT has been called");
       try
       {
         final InitialContext initialContext = new InitialContext();
         if ( initialContext == null )
         {
                final String error = "Could not create initialContext. Errors 
WILL happen"; 
                LOGGER.severe(error);
                throw new ServletException(error);
         }

         // actual jndi name is "jdbc/postgres"
         CustomerloungeServlet.datasource = (DataSource) initialContext.lookup( 
"java:/comp/env/jdbc/postgres" );

         if ( CustomerloungeServlet.datasource == null )
         {
                final String error = "Could not lookup, Errors WILL happen";
                LOGGER.severe(error);
                throw new ServletException(error);
         }
       }
       catch (NamingException e)
       {
         LOGGER.log(Level.SEVERE,"Namingexception in init",e);
          throw new ServletException(e.getMessage());
       }         
    }


And I did not put 

org.apache.commons.dbcp.BasicDataSource as type of the ressource.

I guess it must be org.apache.commons.dbcp.dbcp..... (I guess) but in the 
tomcat source is string compared to:

"javax.sql.DataSource"

You can try that.

Carsten Pohl

Subject: Trouble with context and JNDI resource

I'm using this page, trying to get a resource in a java class:

http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html

I have this in context.xml:


<Context>

    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
        
    <!-- Uncomment this to disable session persistence across Tomcat
restarts -->
    <!--
    <Manager pathname="" />
    -->
                <Resource name="proteus" auth="Container"
type="org.apache.commons.dbcp.BasicDataSource"
              maxActive="100" maxIdle="30" maxWait="10000"
              username="install" password="install"
driverClassName="com.informix.jdbc.IfxDriver"
 
url="jdbc:informix-sqli://sigma:1960/proteus:INFORMIXSERVER=sigma;IFX_LOCK_M
ODE_WAIT=-1;IFX_ISOLATION_LEVEL=1">
                </Resource>             
</Context>

I have this in web.xml:

<resource-env-ref>
                <description>
                        Connection pool for xmlrpc.
                </description>
                <resource-env-ref-name>
                        proteus
                </resource-env-ref-name>
                <resource-env-ref-type>
                        org.apache.commons.dbcp.BasicDataSource

                </resource-env-ref-type>
</resource-env-ref>

I have this code:

l.debug("Created the status xmlrpc class");
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("");
this.setDataSource((BasicDataSource) envCtx.lookup("proteus"));

I get this error:

Name proteus is not bound in this Context
