Some config option isn't setup. What's in this webapp's context xml file? Also what's in it's WEB-INF/web.xml? Lastly, you should have your database driver jar file in tomcat's common/lib (for tomcat v 5.5) or /lib (tomcat v 6). You can also take a look at tomcat's JDBC Datasource howto's on the tomcat website for your version of tomcat which offer a lot of help. --David sam wun wrote: > Thanks David, > > > > After copied the jstl and standard dot jar files into the directory: > > linux:~/tomcat/apache-tomcat-5.5.26/webapps/DBTest/WEB-INF/lib # ls > . .. jstl.jar mysql-connector-java-5.1.3-rc-bin.jar standard.jar > > > > I got the following different errors: > > (In line 4, what is jdbc/TestDB?
