I think your inclinations that Tomcat is not a naming service are correct. I have not seen reference to anything that suggests you can set up resources in Tomcat that are available via JNDI. JBoss, certainly, as it does provide a JNDI server (whatever the appropriate name for that is), as I've used that with JMS/JBossMQ. AFAIK, the Tomcat JNDI setup stuff is just for processes internal to Tomcat, but that is an educated guess, not a known fact :)
-----Original Message----- From: Jason Mowat [mailto:[EMAIL PROTECTED] Sent: Friday, August 15, 2003 12:14 PM To: [EMAIL PROTECTED] Subject: JNDI References To Tomcat 4.1 Greetings, I am trying to create a standalone application that references a DBCP on Tomcat. I'm not sure if I can do this; I've seem some articles that seem to suggest that it can be done, but again, I'm not sure. I've read http://www.mail-archive.com/[EMAIL PROTECTED]/msg08353.html. I have set up in tomcat/conf/server.xml the following context info: <DefaultContext> <Resource name="jdbc/test_db" auth="Container" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/test_db"> <parameter> <name>factory</name> <value>org.apache.commons.dbcp.BasicDataSourceFactory</value> </parameter> <parameter> <name>driverClassName</name> <value>oracle.jdbc.driver.OracleDriver</value> </parameter> <parameter> <name>url</name> <value>jdbc:oracle:thin:@internal.sbgh.mb.ca:1521:test</value> </parameter> <parameter> <name>username</name> <value>test</value> </parameter> <parameter> <name>password</name> <value>test</value> </parameter> <parameter> <name>maxActive</name> <value>20</value> </parameter> <parameter> <name>maxIdle</name> <value>30000</value> </parameter> <parameter> <name>maxWait</name> <value>100</value> </parameter> </ResourceParams> </DefaultContext> Note that I have not created any references in a web.xml, since I will not be running an application, per se, from Tomcat. PERHAPS THIS IS WHERE MY PROBLEM IS? The client code I am using is not a servlet or a JSP; it's a simple piece of code to see if I can communicate with the database pool on Tomcat as configured above. Hashtable env = new Hashtable(); env.put( Context.INITIAL_CONTEXT_FACTORY, "org.apache.commons.dbcp.BasicDataSourceFactory" ); // *** THIS IS ANOTHER AREA WHERE I MAY BE WRONG! *** env.put( Context.PROVIDER_URL, "http://localhost:8080"; ); try { InitialContext initCtx = new InitialContext(env); DataSource ds = (DataSource)initCtx.lookup("java:comp/env/jdbc/test_db"); Connection conn = ds.getConnection(); Statement stmt = conn.createStatement(); ResultSet rset = stmt.executeQuery("SELECT * FROM tbl_test"); conn.close(); initCtx.close(); } catch(NamingException e) { fail("Naming exception thrown"); } catch (SQLException e) { fail("SQL Exception thrown"); } I start Tomcat, assuming that the pool is set up. Then I use the client to try to get an initial context from it. This throws a naming exception, because it doesn't know how to get an initial context for org.apache.commons.dbcp.BasicDataSourceFactory at http://localhost:8080. My first question: can I do this? My second question: If I can't do it like this, do I need to set up a JNDI provider (like on JBoss) and set up the pooling there? My final question: It "feels" as if my problem is simply setting up the PROVIDER_URL properly so that it can get the context from Tomcat. I've done LDAP PROVIDER_URLs before, but never one that gets a data source factory from a servlet container. Can I use http over port 8080 to get the data source factory? Is there a different mechanism for getting the factory from code that is not residing within the servlet container? Can this even be done on Tomcat? I appreciate any help that anyone can provide.
