The first step as part of my journey in learning Spring MVC was to create a private instance of Tomcat 7. The procedure I had followed is documented as part of my earlier post: How to setup multiple instances of Tomcat 7 in Ubuntu.
The next step was to setup Eclipse to recognize the Tomcat 7 private instance.
A new server instance can be registered in Eclipse using
Window -> preferences -> Server -> Runtime Environments menu.
But, when I try add the private Tomcat 7 instance, Eclipse reports that it could not identify the version of the Tomcat and refuses to register the instance.
The solution suggested by David Edwards was to create a link for the
bootstrap.jar library in the private instance folder.
Due to missing fix for the bug-297675 in the
tomcat7-user package, the
tomcat7-instance-create script fails to setup everything as required by Eclipse when executed.
The part of the solution that I followed can be divided into two steps.
Step 1: Create a link to the
lib folder and the
bootstrap.jar file located at
/usr/share/tomcat7 in the
tomcat7 private instance directory.
ln -s /usr/share/tomcat7/lib ~/Workspace/github/springapp/tomcat//lib ln -s /usr/share/tomcat7/bin/bootstrap.jar ~/Workspace/github/springapp/tomcat/bin/bootstrap.jar
In addition, I also had to create a link to
ln -s /usr/share/tomcat7/bin/tomcat-juli.jar ~/Workspace/github/springapp/tomcat/bin/tomcat-juli.jar
Tomcat 7private instance folder created using
Step 2: Either download the catalina.policy file from code repository or from within the general Tomcat 7 instance configuration folder. For instance:
# If you opt for downloading the file - replace 'precise' with the right name of your Ubuntu release. curl http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/precise/tomcat7/precise/download/head:/catalina.policy-20110521092527-dk8tcyjy21h8eu9h-1652/catalina.policy > ~/Workspace/github/springapp/tomcat/conf/catalina.policy
Note: Make sure that you are downloading the latest version of http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/precise/tomcat7/precise/view/head:/conf/catalina.policy file.
Eclipse should be able to recognize the version of Tomcat without issues.
Meanwhile, shutdown and restart the private instance using the commands:
settipalli@settipalli-ubuntu:~/Workspace/github/springapp/tomcat$ ./bin/shutdown.sh # Followed by: settipalli@settipalli-ubuntu:~/Workspace/github/springapp/tomcat$ ./bin/startup.sh
