Unable to debug tomcat server using eclipse - debugging

I'm using:
Spring Tool Suite Version: 3.2.0.RELEASE
Tomcat v7.0.42
When I just run my tomcat server everything is fine but I'm unable to debug it even locally. It produces following error:
Startich Apache Tomcat v7.0.42 at localhost has encoutered a problem.
Server Apache Tomcat v7.0.42 bat localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.
I've tried the following:
increase the timeout.
remove all the apps before starting the debugging.
install new instance of tomcat (the only configuration that I've did on fresh install is turning on Use Tomcat installation and Never publish automatically).
But it didn't help, I still can only run the tomcat, without the debug option. Does anyone know how to make this debugging work?

When I've used new, clear workspace for Spring Tool Suite, debugging started to work.
Cheers,

Debug J2EE Applications on IntelliJ Community Edition and Tomcat8 (running as a service)

I've searched a lot on Remote Debugging a REST APIs written in Java using IntelliJ IDEA Community Edition.
My Setup:
Windows 10
Tomcat installed as a windows service
Java 8
Intellij Community IDE
Finally after some googling and sifting through SO, found a solution that works. Posting it below.
Part I. Running Tomcat in Debug Mode
When running Tomcat8 as a service
Open {$TOMCAT_HOME}\bin\Tomcat8w.exe
Under Java > Java Options add the following lines to enable the debug port 8001:
-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8001
Restart the Tomcat Service
Part II. Attaching IntelliJ IDEA Remote Debugger
Create a new Run Configuration using the Remote Template.
Under Configuration > Settings Change the Port to 8001
Run the new config by clicking on the debug icon and IDEA will connect to the debug port of Tomcat

How to remotely debug the webapplication running on tomcat service?

can't shutdown tomcat service on Mac

I installed the Apache Tomcat/7.0.65 on my Mac, then, run the startup.sh. It works great fine and the service is available immediately. But when I run the shutdown.sh to stop the service. It seems that the shell scripts can not aware of the tomcat running. Would someone please help me with this problem?
I had a similar problem. In my case, although running <Tomcat Root>/bin>./shutdown.sh was technically working (the tomcat process was being killed), the tomcat service was restarting automatically (after a few seconds).
If you run <Tomcat Root>/bin/catalina.sh stop or <Tomcat Root>/bin/shutdown.sh and you see that after a few seconds tomcat restarts => that basically means that you are not able to shutdown tomcat for good. Thus, if you want to make sure that tomcat does not restart automatically, run brew services stop tomcat.
OBS: If you want to find what is your <Tomcat Root> run brew ls tomcat

intellij idea 14 cannot connect to debug tomcat7 service

Ok, I think I tried everything before I am posting this question. Please tell me, what I am (Still) missing. I keep getting "unable to connect" exception (unable to connect hostname:6012), I changed from default port 1099 and it still didn't help.
version of IntelliJ 14.0.2
Tomcat 7.0.52
Tomcat is running as a service so, I configured on the UI interface of tomcat.exe (java tab) the following JAVA_OPTs
-Xdebug
-Xrunjdwp:transport=dt_socket,address=57497,server=y,suspend=n
-javaagent:C:\Users\username\.IntelliJIdea14\system\groovyHotSwap\gragent.jar
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=6012
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcatalina.home=C:\Tomcat 7.0
-Dcatalina.base=C:\Tomcat 7.0
-XX:MaxPermSize=512m
I made sure the port 57497 is open (open the firewall and telnet).
And on IntelliJ, I made a remote server connection. Please find attached
pictures. Both intellij and tomcat are running on the same system. I have a static dns setup. sometimes i get connection timedout exception.
server tab
connection tab
Here's my config.
Tomcat JAVA_OPTs to enable remote debugging:
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5007
In IntelliJ, I don't use the Configuration-Type 'Tomcat'. In my case 'Remote' works pretty well (I would post an image but I ain't got 10 reputation...). You only need to configure your host and port on the config sheet.
I use IntelliJ 14.0.3 and I had the same issue, though with Jetty. Switching to using the remote instead of jetty -> remote worked. I'm guessing they're both supposed to work differently. I just haven't figured out why there are two different options to remote debug.

Confliting PORTNO of Tomcat

I have installed Apache Tomcat 7.0.32 and I am using Eclipse JUNO. But whenever I am using Eclipse I am not getting result from Server rather than I am getting Server can not start within 45sec.
Try changing connection port in server.xml

tomcat debugging

I am working on a project where the backend code is in Java.
I want to debug this code and am running tomcat in the debug mode correctly .
I have the Java code in Eclipse where I set up a new debug config for Remote Java Application and start the debugging.It shows no error but it is not breaking at the breakpoint.
So the Tomcat Webapps folder has only a copy of the Servlet classes and my Java code is in a folder at some other place.
Is this the reason that I am not being able to link them properly
You have to start tomcat with the JPDA options in order to debug remotely. Under *nix, issue "catalina jpda start" instead of "catalina start".
If you want to do a remote debug to figure out a problem in code, then your code locally must be the same. Also remember to connect to the correct port, 8000, I believe.
