Check the configuration: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html#Database%20Connection%20Pool%20(DBCP)%20Configurations 5.5 has a different set up than 5.0 . You also need a resource link. See: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/globalresources.html at the bottom of the page. It has also be noted on the list that the odbc drivers are not suited for production. But this will not cause your problem.

The context path attribute is the URL path used by browsers to retrieve your web pages, i.e. http://yourhost:yourport/path. It's not a filesystem path. The context docBase is the root of your webapp. It should point to a directory which has a WEB-INF subdirectory containing web.xml. Therefore, I'm guessting your docBase is just ROOT and your path is . Drop the Web-INF/classes part from both.

In common/lib or WEB-INF/lib? It should be the former if you're using DBCP this way. The latter would work using the primitive DriverManager approach and fail with DBCP.

RE: Cannot create JDBC driver of class '' for connect URL 'null'
Hi, Context path=/ROOT/WEB-INF/classes docBase=ROOT/WEB-INF/classes/JITS I really doubt you mean these. The context path attribute is the URL path used by browsers to retrieve your web pages, i.e. http://yourhost:yourport/path. It's not a filesystem path. The context docBase is the root of your webapp. It should point to a directory which has a WEB-INF subdirectory containing web.xml. Therefore, I'm guessting your docBase is just ROOT and your path is . Drop the Web-INF/classes part from both. Resource name=jdbc/myoracle auth=Container type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver url=jdbc:oracle:thin:@newton.sheridanc.on.ca:1522:DB2 username=jits password=mypassword maxActive=20 maxIdle=10 maxWait=-1/ This looks reasonable.

Re: Cannot create JDBC driver of class '' for connect URL 'null'
Hi ! i'm sure everything on the database end is fine. All i'm doing in the Java file ( located in C:\jakarta-tomcat-5.5.4\webapps\ROOT\WEB-INF\classes\JITS ) is making a database connection at this time. if I use: Class.forName(oracle.jdbc.driver.OracleDriver); conn = DriverManager.getConnection(jdbc:oracle:thin:@newton.sheridanc.on.ca:1522:DB2, jits, pass); stmt = conn.createStatement(); works fine. So, Tomcat finds the Oracle JDBC driver fine and the version of the JDBC driver is fine. I think it must be something in the server.xml or web.xml or another xml file where Tomcat is expecting to see the parameters for the jdbc driver classname, and the connectionURL..

Re: javax.servlet.ServletException: Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver
Hi Isen. This is a common problem and usually means your JNDI naming is inconsistent or your missing config info in one or more of the following files: server.xml ( if you defined your JDBC resource here ) [context].xml web.xml Java code Essentially make sure there are no spelling/capitalization mistakes and all the necessary parts are there, including the JDBC driver jar file in the common/lib directory. The JNDI howtos on the Jakarta site is a good place to look: (these are for tomcat 5, there should be equivalents for tomcat 4) http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-resources-howto.html http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html If you're still running into brick walls, post appropriate sections of all the above files replacing security sensitive sections (database username, password) with *'s or something. --David Isen,Ciji wrote: Hi, I am using tomcat-5.

Hi,
If it's inside GlobalNamingResources, you need a ResourceLink to it in
your Context.
You should also place a resource-ref in your web.xml, but you may have
done that already (you didn't post web.xml).

Re: javax.servlet.ServletException: Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver
Oh ya. That was the problem. :-)) It was searching for the resource in
the context. But i am surprised that its not able to access a Global
resource. Logically the top level resource ought to be available at the
lower levels too.

Re: Cannot create JDBC driver of class '' for connect URL 'null'
Hello My web.xml contains: That looks the same as mine (which works) so no problem there. You do not actually *need* this element in the deployment descriptor if you are using Tomcat 5, but it makes your code portable, should you ever (God forbid!) switch to another servlet container. My $TOMCAT_HOME/conf/server.xml contains the following... BTW, it is $CATALINA_HOME that matters - $TOMCAT_HOME is not used. Looking at your resource definitions, this sub-element: parameter nameurl/name value jdbc:postgresql://localhost/mydb /value /parameter Maybe should read: parameter nameurl/name value jdbc:postgresql://localhost:5432/mydb /value /parameter Mine, at least, needs a port number to be specified. The rest of the resource element looks okay to me. Also, your look-up code looks good too, so my only guess is that you have forgotten to put the PostgreSQL JDBC driver under the container's classpath. You probably have the driver located under your application's 'WEB-INF/lib' directory. Try placing the driver in the '$CATALINA_HOME/common/lib' directory, but do not have it both places! (Remove it from the 'WEB-INF/lib' directory.) Also, make sure you have a driver named 'pg74.1jdbc3.jar'. The one that comes bundled with the PostgreSQL 7.4 RPM is out of date. You can download the 7.4 driver from PG's JDBC site. Good luck.

Re: Cannot create JDBC driver of class '' for connect URL 'null'
Thanks Harry but the problem is that it is not even trying to load the Postgres driver - it is not getting that far. It is trying to load JDBC driver class '' (empty string) and is trying to access JDBC URL of 'null'. It seems that the ResourceParams section is not being used. I do have the postgres jar deployed to common/lib. Thanks.

Re: Cannot create JDBC driver of class '' for connect URL 'null'
I found the problem. To get it working I needed to have the Resource and ResourceParams in the Global section and then add a ResourceLink in the context for my webapp. This enabled Tomcat to resolve the parameters.

Re: Cannot create JDBC driver of class '' for connect URL 'null'
I'm glad you sorted yourself out Andy. Just for the record, you *can* define the resource (and its parameters) within the context of an application - as opposed to making it a global resource that requires a resource link. I have it working that way, and I suspect so do many others because this is the way the Tomcat documents indicate things should be done. See, for example: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-how to.html In that document the resource element is defined as part of a context. I'm tempted to think that you had something broken in your code, before, and when you rehashed everything the other way it worked because you got it right. IOW it's another way to skin this particular cat (oops!) but not the only way. All the best Harry I found the problem. To get it working I needed to have the Resource and ResourceParams in the Global section and then add a ResourceLink in the context for my webapp. This enabled Tomcat to resolve the parameters.

Hello What is postgresql JAR? It is the JDBC driver for the PostgreSQL database. You do not need it if you are connecting to an Oracle database - but, of course, you need the Oracle equivalent, which I am sure you already have if you have managed to make 'single' connections, as you say. I cannot help you with your problem, but the key words in the error output would seem to be: 'Connection refused'. Make sure that *all* your connection details are specified correctly.

Re: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause: java.sql.SQLException: No suitable driver
Hello Dan, I finally got it to work. The problem is that for directories in webapps a Context is automatically created, even if it is already declared in server.xml. The automatically created Contexts do NOT contain the context specific configuration of server.xml. The outcome is that a) a context is created twice and b) for the second instance the resources are not found. The addition of deployOnStartup=false on all of my Host elements solved my problem.

Re: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause: java.sql.SQLException: No suitable driver
Andreas, Not sure if you got a response yet. Generally, when I have seen the error above, it seemed to be coming from the web app saying that it didn't get the parameters. I am fighting this same error. Strange enough, though, I had it working as you have yours setup. Another thing is that the order that the XML elements are in is critical...i.e. it needs to follow the dtd. This means that resource-ref elements need to be in the right order relative to the other elements(like servlet and servlet-mapping). Anyway, if it was a driver problem like the jar was in the wrong place, the log would have told you it can't find the class. If you have figured out how to get this working or if you have gotten it to work with the gloabal jndi resource context, please let me know. I will check back later and I will help you figure it out as I will be working on it too. Dan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I get this error using Tomcat 5.0.18 under Debian/Linux. Using the same configuration under Windows XP, there is no problem. Using the same application under Tomcat 4.1.27, there is no problem (either Linux or Windows).

I have searched for this problem on this Mailing List, but got no clue. I am using a Context local DataSource (no Global), and have everything strictly setup as described in the JNDI HowTo.
