JDBC Data Sources 0. The following examples demonstrate how you can use servlet mapping in your Web application. If set to true, a connection is considered abandoned and eligible to be reclaimed by the connection pool if it has been idle longer than the removeAbandonedTimeout. I am using Tomcat 4.1.30 and am still getting an error that saysorg.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause:java.sql.SQLException: No suitable driverHere is my server.xml http://hightechcomp.com/driver-class/driver-class-c-resume.html
A $PATH, LD_LIBRARY_PATH problem. parameters are one or more name-value pairs containing information sent from the browser that can be used in your servlet. Default is 8 maxWait The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception, or Ensure that these are appropriate to maintain the security of your installation. 3.
Setting such properties using the Tomcat BeanFactory will fail with a NamingException. For people who is developing web modules and NOT putting into the ROOT context, the jdbc setup can be done and deployed consistently, it has been discussed quite a bit from Default: 30*60*1000 (30 minutes) testWhileIdle - true or false: whether a connection should be validated by the evictor thread using the validation query while sitting idle in the pool. Default: -1 (disabled) numTestsPerEvictionRun - The number of connections that will be checked for idleness by the evictor during each run of the evictor.
Additional information about using various J2EE and Weblogic Server services such as JDBC, RMI, and JMS, in your servlet are discussed later in this document. This example assumes that you are using the HypersonicSQL database JDBC driver. Open your server.xml and search for

It took so much time because i was reading lots of junk on the net and confusing. https://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-examples-howto.html I created a jar file using testpkg directory & putit in TOMCAT_HOME/common/lib as well asTOMCAT_HOME/webapps/web/WEB-INF/lib directory.4.
Also http://tomcat.apache.org/tomcat-6.0-doc/config/context.html has section about where context can appear. 3) Am I right in assuming you don't need to place in server.xml. In Tomcat 5.5, files terajdbc4.jar and tdgssconfig.jar should be copied to the C:\Tomcat\common\lib directory. You should have installed Oracle8i(8.1.7) client from cd, and download the suitable JDBC/OCI driver(Oracle8i 18.104.22.168 JDBC/OCI Driver) from otn.oracle.com. However, feedback from tomcat-user has shown that specifics for individual configurations can be rather tricky.

Every time your web application calls lookup() on a context entry that is bound to this factory (assuming that the factory is configured with singleton="false"), the getObjectInstance() method is called, with The schema used will be the default schema for the user scott. What does "I'm catching a 4:00 at Logan" mean? http://hightechcomp.com/driver-class/driver-class-for-ojdbc14-jar.html Tomcat includes a UserDatabaseFactory that creates UserDatabase resources backed by an XML file - usually tomcat-users.xml The steps required to set up a global UserDatabase resource are described below. 1.

Installation See the DBCP documentation for a complete list of configuration parameters.
Code example You can use the same example application as above (assuming you create the required DB instance, tables etc.) replacing the Datasource code with something like Context initContext = new Can anyone see why i'm getting this error? In this way, the application is totally insulated from changes in the email server configuration environment - it simply asks for, and receives, a preconfigured session whenever needed. Not only can it recover them, but also generate a stack trace for the code which opened these resources and never closed them.

Introduction UserDatabase resources are typically configured as global resources for use by a UserDatabase realm. However, the Commons DBCP (Database Connection Pool) which is used by the Tomcat application server can validate connections before issuing them by running a simple SQL query, and if a broken Thanks for context.xml needed changes. The classesXXX.zip file and Oracle client software versions must match.
maxIdle — The maximum number of connections that can sit idle in this pool at the same time. by Waseem Quraishi on August 05 2005 13:10 EDT Nothing works by Bryon Lape on August 22 2005 19:03 EDT Hi, I got procedure for connecting jndi using tomcat by null Too many options! This is generally ignored in Tomcat object factories.
There is usually no need to know the implementation class. –Mark Rotteveel Mar 11 '14 at 8:18 @nigelthomas would you mind accepting an answer? –Jason Pyeron Jan 24 at Please let us know if you have any other tested configurations that you feel may be of use to the wider audience, or if you feel we can improve this section You can put it in context.xml instead?4) Why use server.xml over context.xml or vice-versa? Default: 8 maxWait - The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception.
Is this factory attribute the same one defined in element of which I believe I am right in saying can only be in server.xml and would be same one I mentioned
