I modified the web.xml file from a dynamic web project in Eclipse EE and now I can't start the Tomcat server.
Error shows:
Server Tomcat v8.0 Server at localhost failed to start.
and in the console:
SEVERE: Failed to destroy end point associated with ProtocolHandler ["ajp-nio-8009"]
How can i fix this ?
The service is already running on port 8009. You should kill it and try tomcat restart.
Try this :
Terminate the tomcat, restart it from command prompt and then first undeploy and then redeploy your web application.

Trying to deploy Midpoint OpenSource IDM software on Windows server
Runing JAVA 9.0.1 and Tomcat Apache 8.5
Deployment of the WAR file seems to succeed but application does not start
On Tomcat Web Application Manager I get the error:
FAIL - Application at context path [/midpoint] could not be started
In the Catalina logs all I can see is:
SEVERE [http-nio-8080-exec-38] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file
SEVERE [http-nio-8080-exec-38] org.apache.catalina.core.StandardContext.startInternal Context [/midpoint] startup failed due to previous errors
I'm using NetBeans IDE and Maven with Spring Boot. Whenever I run my app more than once, I get this error:
o.a.coyote.http11.Http11NioProtocol : Failed to start end point associated with ProtocolHandler ["http-nio-8080"]
java.net.BindException: Address already in use
spring boot java.lang.IllegalStateException: Tomcat connector in failed state
I'm assuming this means that Tomcat isn't getting shutdown. How can I properly shutdown the embedded Tomcat in Spring Boot (preferably from the IDE)?
I found a netbeans configuration that fixed my problem. See this screenshot: https://bugzilla-attachments-241321.netbeans.org/bugzilla/attachment.cgi?id=151222
After installing Apache tomcat8 I am getting below home page.
I just installed tomcat8, start service and hit url
http://localhost:8080/
I haven't created any project.
It looks to me that the page in your screenshot is being served up by Oracle Application Express (APEX), not Tomcat.
APEX typically uses port 8080, and if you started this before starting Tomcat, Tomcat will be unable to use port 8080. To confirm that this is the case, take a look in your Tomcat stderr log file (it should be under C:\Tomcat 8.0\logs and have a name like tomcat8-stderr.2014-09-21.log). It will quite probably contain an exception whose stacktrace begins as follows:
21-Sep-2014 12:09:15.607 SEVERE [main] org.apache.coyote.AbstractProtocol.init Failed to initialize end point associated with ProtocolHandler ["http-nio-8080"]
java.net.BindException: Address already in use: bind
at sun.nio.ch.Net.bind0(Native Method)
I would recommend that you change Tomcat to use another port. To do this, open your server.xml file (in C:\Tomcat 8.0\conf\). There should be a Connector element in here with an attribute port="8080": change this port number to 8081 (say) and restart Tomcat.
Ok, try this
1- Download a tomcat version.
2- unzip it in a folder. (let say C:\Java)
3- open a command prompt window
4- Type C:\Java\ your tomcat installation \bin\startup.bat
5- Access http://localhost:8080
Looks like you have not started tomcat yet.
Are you sure you have followed a guide like this ?
I am unable to shutdown tomcat. When I do ./shutdown.sh, I don't see any error, but the process still seems to be running. When I kill the process (kill -9), the process gets killed. After this, if I do a startup, and shutdown again, I see the same problem. How do I gracefully shut it down? Why is this happening in the first place? Please help me.

Also, I see my catalina.out is rather too short. There is no port number info getting written to it at all. This is all I see everytime I startup.

Something seems to be terribly messed up. I can't understand what. Please advise.
I am running tomcat 7.0.50 on Mac OS.
Judging by the logs, it is evident that tomcat is not starting up at all as it should be. I can advise a couple of other tests as well like to
Verify whether or not the ports are getting bound by the tomcat service or not. You can do this by issueing the command netstat -tuplen on the terminal and check to see if port 8080 is getting bound by the tomcat instance or not.
Check to see if you can ping the instance. Try to ping the tomcat instance from a local machine. Then try to ping the public ip of the server to verify whether that server is responding correctly or not
Verify that you have, infact, the complete tomcat template as is used by your other servers. Verify the tomcat installtion folder and compare it with the other tomcat templates as used in rest of your servers. Make sure all folders are there, all configuration (default tomcat config) files are present.
(Just a hunch) Verify read/write/execute privileges as well
Remove your application, shutdown tomcat, empty the logs, and then restart tomcat and re-deploy your application and then view the logs to see if you get some error
Point 3 seems more likely that you have an incomplete tomcat instance, so I advise you to make a copy of the tomcat instance used in any other server and use it in this server to make sure that the server environment is infact how it should be
I'm trying to initiate a remote debugging session on my PC with Eclipse & Tomcat.
I managed to run tomcat (not through eclipse) with the following params:
set JPDA_TRANSPORT=dt_socket
set JPDA_ADDRESS=5050
cataline jpda start
The server starts ok, this is the outcome:
Using CATALINA_BASE: "C:\Java\Tomcat"
Using CATALINA_HOME: "C:\Java\Tomcat"
Using CATALINA_TMPDIR: "C:\Java\Tomcat\temp"
Using JRE_HOME: "C:\Java\jdk1.6.0_27"
Using CLASSPATH: ...
Listening for transport dt_socket at address: 5050
...
...
INFO: Server startup in 12502 ms
Now, I opened eclipse, and loaded the relevant project.
I set a new debugging configuration using Remote Java Application with localhost and the right port. however when I run it, I get this error message:
Failed to connect to remote VM. Connection refused.
Connection refused: connect
Can't really understand where is the problem. this is all local inside the PC, so there shouldn't be any firewalls involved, can someone think of something ?
Found the solution. apparently the connection was made, but Eclipse & Tomcat don'tt show any notification or status regarding it.
Then, when you initiate the connection again, you get the error because you're already connected.
I think that a small notice, either from Eclipse, or from Tomcat would be nice.
Try adding the following debug options directly to the JVM startup by directly modifying the catalina startup script
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5050
There could be problems when there are code mismatches between eclipse and tomcat. So when it matches the error will disappear
You can configure it in remote java application section in debug configuration.
