I had an application running on an older release of Tomcat where I had placed important info in the server.xml file regarding the applications context. This info initialized a connection pool to a database and provided the appropriate data regarding the number of connections, user name and password, etc. The entire xml data is provided below.
I'm trying to port over my application to the latest release of Tomcat version 5.5 and I'm having difficulty in determining where to place the context information for the application. This latest release doesn't seem to include any context info on any of the example applications in the server.xml file, so where does one put this context info? I noticed there is an xml file named context.xml in the Apache Software Foundation\ Tomcat 5.5\conf directory, and even tried appending my own context info there, but Tomcat didn't like my doing that!
<!-- New Context for MySQL Database Driver --> <Context path="/school" docBase="school" debug="0" reloadable="true" crossContext="true">
<!-- Maximum number of dB connections in pool. Make sure you configure your mysqld max_connections large enough to handle all of your db connections. Set to 0 for no limit. --> <parameter> <name>maxActive</name> <value>3</value> </parameter>
<!-- Maximum number of idle dB connections to retain in pool. Set to 0 for no limit. --> <parameter> <name>maxIdle</name> <value>3</value> </parameter>
<!-- Maximum time to wait for a dB connection to become available in ms, in this example 10 seconds. An Exception is thrown if this timeout is exceeded. Set to -1 to wait indefinitely. --> <parameter> <name>maxWait</name> <value>10000</value> </parameter>
<!-- MySQL dB username and password for dB connections --> <parameter> <name>username</name> <value>sqlapp</value> </parameter> <parameter> <name>password</name> <value>aplus</value> </parameter>
<!-- Class name for mm.mysql JDBC driver --> <parameter> <name>driverClassName</name> <value>org.gjt.mm.mysql.Driver</value> </parameter>
<!-- The JDBC connection url for connecting to your MySQL dB. The autoReconnect=true argument to the url makes sure that the mm.mysql JDBC Driver will automatically reconnect if mysqld closed the connection. mysqld by default closes idle connections after 8 hours. --> <parameter> <name>url</name>
With Tomcat 5.5 (of which I have zero experience), it might be even more strictly enforced as to the location of the context configuration information. I seem to recall that the DataSource configuration changed LOTS. Everything that was a pair of tags is now attributes within one tag (or something like that).
It is better that you start with a clean server.xml and reconfigure your application, using the TC 5.x docs as a guide. Things move around.
