Upgrade from Tomcat 5 to Tomcat 6 on Windows Server

Current Customers will need to upgrade to JDK 1.6 before commencing with the instructions listed below. This information can be found here.

Current users of m-Power who run Tomcat 5 on Windows now have the option of upgrading to Tomcat 6. The instructions provided below will walk users with the process of upgrading their application server.

1. 1. Stop and Remove existing Tomcat service.
     - Open a command window and navigate to c:\m-power\tomcat\bin.
     - Type "service.bat remove"
     - Close command window
2. 2. Rename current Tomcat folder (c:\m-power\Tomcat) to TOMCAT5
3. 3. Download Tomcat.zip from here and extract to c:\m-power
4. 4. If you are using any non-default ports, be sure to modify the c:\m-power\tomcat\conf\server.xml to reflect your customization.
5. 5. Next, go into c:\m-power\TOMCAT5\common\lib and copy the following files to c:\m-power\mrcwebgui\WEB-INF\lib
     - ant.jar
     - ant-launcher.jar
     - commons-pool-1.2.jar
6. 6. Next, go into c:\m-power\TOMCAT5\shared\lib and copy all files to c:\m-power\mrcwebgui\WEB-INF\lib and c:\m-power\mrcjava\WEB-INF\lib
7. 7. Copy tools.jar from C:\Program Files\Java\jdk1.6.0_07\lib to c:\m-power\tomcat\lib.
8. 8. Next, go into c:\m-power\mrcwebgui\WEB-INF\. Edit the web.xml file Find the following text:


     <servlet>
     <servlet-name> servletToJsp </servlet-name>
     <servlet-class> servletToJsp </servlet-class>
     </servlet>

Directly beneath it, copy this text:

     <servlet>
     <servlet-name>invoker</servlet-name>
     <servlet-class>org.apache.catalina.servlets.InvokerServlet</servlet-class>
     <init-param>
     <param-name>debug</param-name>
     <param-value>0</param-value>
     </init-param>
     <load-on-startup>2</load-on-startup>
     </servlet>


9. 9. Please repeat the step above, however this time do this to the c:\m-power\mrcjava\WEB-INF\web.xml file. Note: There are two areas that appear similar. Be sure to copy the above code near line 22 (Do not place at the end of the document).
10. 10. Next, go into c:\m-power\ and edit the “start_tomcat.bat” file.
     - Change this line: set JAVA_HOME=C:\j2sdk1.4.2
     - To read this: set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_07
11. 11. Now that everything is pointing to the new JDK, you can start Tomcat from the batch file to ensure that m-Power is running and that you can build/run applications.

Now that everything works, how can we install as a service?

12. 1. The first step is right click “My computer” and go to “Properties” Click Advanced and go to Environmental Variables.
     - From here, add ;C:\Program Files\Java\jdk1.6.0_07\bin to the PATH. Remove C:\j2sdk1.4.2\bin from the path if the entry exists.
     - This step requires your machine to be restarted.
13. 2. Next, go to a PC command line.
     - CD to c:\m-power\tomcat\bin
     - Type service.bat install Tomcat6
14. 3. Next, type tomcat6w //ES//Tomcat6
     - A window will pop up. Switch to the Java tab.
     - Change the Java Virtual Machine option to: C:\Program Files\Java\jdk1.6.0_07\jre\bin\server\jvm.dll
     - Add the following four lines to the end of the Java Options window:
          -Xmx512m
          -Xms512m
          -XX:PermSize=256m
          -XX:MaxPermSize=256m
     - Hit OK.
     - Start the service as you usually would

Congratulations -- you have successfully converted your Tomcat version to Tomcat 6!
