On the topic of debugging, see the following page: https://wiki.apache.org/tomcat/FAQ/Developing The following two items on that page should be interesting for you: a) "Official Eclipse IDE Web Tools FAQ for Tomcat" with links to Eclipse documentation b) "How do I configure Tomcat to support remote debugging?" This is for the use case when you start Tomcat separately and attach a debugger to an already running Tomcat. 2. On a topic of simply running Tomcat (not debugging), official documentation is "RUNNING.txt" file. There is also http://tomcat.apache.org/tomcat-8.5-doc/setup.html Environment variables used by launch scripts are documented in a comment at the top of those scripts (catalina.bat, catalina.sh). > Currently, I have the below inside my arguments : > > -Dcatalina.base="C:\Users\Karen.Goh\workspace3\.metadata\.plugins\org.eclipse.wst.server.core\tmp0" -Dcatalina.home="C:\Program Files\Apache\apache-tomcat-9.0.4-windows-x64\apache-tomcat-9.0.4" -Dwtp.deploy="C:\Users\Karen.Goh\workspace3\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps" -Djava.endorsed.dirs="C:\Program Files\Apache\apache-tomcat-9.0.4-windows-x64\apache-tomcat-9.0.4\endorsed" > > Is this the part that is causing Tomcat to just hang ? Or I have missed out something I am not aware of. Kindly highlight please. 3. When Tomcat starts, its actual arguments are printed by VersionLoggerListener. You can see them in your previous e-mail, Search for "Command line argument" http://markmail.org/message/tgymk3r43ox5ggps > Cos I can't proceed with any debugging at all as in run the green button : Please see this attachment at https://imgur.com/OQLyJFb 4. In your image I see that your Tomcat is not running (The "Console" view at the bottom says "<terminated>". The "Servers" view says "[Stopped, Synchronized]".) How did you start it? 5. My recipe will be: - In the "Servers" view select the server and deploy you application onto it (right click -> context menu -> ...) - Then click the small green "bug" button in the toolbar of this view (in the small toolbar right above "Servers" view, not the one in the main toolbar). The server should launch in debug mode. It is not working following your step above. If I started Tomcat and then click the green 'debug' button I will have problem going back to the Java EE view to click on the tutorRegister.jsp page for it to run in debug mode. Last time, when I did debug - it was so simple. I just click on tutorRegister.jsp and Eclipse will prompt me for change to debug perspective. After that, when I complete the form and hit submit, the IDE will then go to the breakpoint and allows debugging from there. Can I know how to make this happen again ?
