Hi!
I am Pranay. I want to connect my JSP with MySQL. Will you please help me? I want the detail-code and pre-coding instructions.....
General Informations:
1. JDK 1.5.0
2. Apache Tomcat 4.1
3. MySQL Server 5.5
4. MySQL Connector/J 5.0.4
5. PATH
C:\Program Files\Java\jdk1.5.0\bin
Plz consider that I have a table in my MySQL database nametab1 which has fields: name,roll,date_of_birth.
Plz help me.....
Thanx...
The tomcat manual has a guide on setting up a datasource using MySQL.
http://tomcat.apache.org/tomcat-4.1-doc/jndi-datasource-examples-howto.html
If you can, I would consider upgrading to Tomcat 5.5 however. That gives you access to servlet 2.4 / jsp 2.0 features and it is generally more stable.
Thanx for replying....
I can't understand the following steps:
2. server.xml configuration
Configure the JNDI DataSource in Tomcat by adding a declaration for your resource to $CATALINA_HOME/conf/server.xml.
Add this in between the </Context> tag of the examples context and the </Host> tag closing the localhost definition.
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_DBTest_log." suffix=".txt"
timestamp="true"/>
<Resource name="jdbc/TestDB"
auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/TestDB">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<!-- 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>100</value>
</parameter>
<!-- Maximum number of idle dB connections to retain in pool.
Set to 0 for no limit.
-->
<parameter>
<name>maxIdle</name>
<value>30</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>javauser</value>
</parameter>
<parameter>
<name>password</name>
<value>javadude</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>
<value>jdbc:mysql://localhost:3306/javatest?autoReconnect=true</value>
</parameter>
</ResourceParams>
</Context>
3. web.xml configuration
Now create a WEB-INF/web.xml for this test application.
