Dear all,
I've tried to search for it but couldn't find an answer.
Please try to help me.
I've created an application and deployed and run successfully in the first
PC.
I copied everything over, installed everything as the first PC.
1) I've the mysql-connector-java-3.1.12-bin.jar in the common/lib.
2) Added this to the server.xml:
<Context>
<Resource name="jdbc/MySQLDB" auth="Container"
type="javax.sql.DataSource" username="root" password="password"
driverClassName=" com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/transport"
maxActive="8" maxIdle="4"/>
</Context>
3) Added this to the web.xml
<description>MySQL Connection</description>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/MySQLDB</res-ref-name>
<res-type> javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
4) Set the environment variable: CLASSPATH=C:\Program Files\netbeans-
5.0\enterprise2\jakarta-tomcat-5.5.9\common
lib
Now when i deploy and start the application on the Tomcat,
Tomcat logs give me this error:
