As described in To Prepare to Install Agent for Apache Tomcat 6.0, you can install Agent for Apache Tomcat 6.0 on a .exe version of Apache Tomcat 6.0. However, you must implement the steps in this task prior to installing the agent for the deployment to work.
The Apache Tomcat 6.0 bits with the .exe extension do not contain certain files (scripts, JAR files, etc.) required by the agent. Therefore, you must copy the required files from the .zip bundle to the Apache Tomcat 6.0 installation base.
Download the .exe and the .zip versions of Apache Tomcat 6.0.
For example, you could download the two following Apache Tomcat 6.0 versions:
apache-tomcat-6.0.14.exe
apache-tomcat-6.0.14.zip
Install Apache Tomcat 6.0 using the .exe version.
If the version of Apache Tomcat 6.0 is indeed 6.0.14, the following would be a feasible location for CATALINA_HOME:
/opt/apache-tomcat-6.0.14
In a directory separate from the .exe distribution, unzip the apache-tomcat-6.0.14.zip file.
Copy the following scripts from the unzipped bundle to the bin directory of the installation (${CATALINA_HOME}/bin):
catalina-tasks.xml catalina.bat catalina.sh commons-daemon.jar cpappend.bat digest.bat digest.sh jsvc.tar.gz service.bat setclasspath.bat setclasspath.sh shutdown.bat shutdown.sh startup.bat startup.sh tomcat-native.tar.gz tool-wrapper.bat tool-wrapper.sh version.bat version.sh
After you have implemented this task, the best practice is to start and stop the Apache Tomcat 6.0 instance using the command line since problems have occurred in this scenario when attempting to stop and start the server via services.
At this point, you can install Agent for Apache Tomcat 6.0.
