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
