Tomcat Server does not start from the command line - java

I used Eclipse EE luna. I couldn't start the tomcat7 server from inside eclipse while i can start it from cmd.It gave Server Tomcat v7.0 Server at localhost failed to start. error.I tried all the answers here but none of them helped me. Then i deleted my eclipse EE luna and downloaded juno package.
Here is the problem : This time i can start tomcat server from inside the eclipse and everything works fine, however, after stopping server from eclipse, i can't start it from cmd(My opinion is startup.bat thinks that server is still running and cancels the process).Therefore I can't deploy my projects under \tomcat7path\webapps\, just running it from eclipse.(It also runs from web browser. Actually this is an another question. How can it run from browser while "myproject" doesn't exist under \tomcat7path\webapps\ directory.)
I am stuck on this, any help would be appreciated.
More informaton: I am developing servlets using eclipse ee juno, on tomcat-7.0.55

Ok, i have solved the problem, finally. I removed JAVA_HOME and JRE_HOME environment variables, then opened a new command line window and started tomcat. It gave "Neither the JAVA_HOME nor the JRE_HOME environment variable is defined.At least one of these environment variable is needed to run this program" error.After redefining JAVA_HOME, i started a new cmd and tried again. This time it worked.

Java Web app failed to start on Tomcat 9 with Netbeans 11 on Mac OSX Sierra

I have an issue with Netbeans 11 and Tomcat 9 on Mac OSX Sierra (10.11.2)
I've a Java Web Application (non-maven project) and I'm not able to deploy the WAR into the running Tomcat.
After several minutes an error is raised in console:
/build-impl.xml:1092: Deployment error: Starting of Tomcat failed.
I'm using Oracle JDK 1.8
I've searched for this kind of issue and found other people struggling with the same error so I've tried the suggested solutions but nothing have worked
I've changed the config in order to have "No proxy" setting
I've also tried with Tomcat 8 and Tomcat 7 but same error occurs.
I've added the server attribute to the Tomcat connector as metioned here: Starting of Tomcat failed from Netbeans
but nothing works.
For the sake of completeness I say that the Tomcat starts correctly because respond on localhost:8080 (I can see the admin page).
I've also copied the WAR into the webapps folder and file was correctly uncompressed and the Web application, in this way, is correctly running.
It's seems that Netbeans is not aware of Tomcat start so deploy is not performed.
Thanks in advance and sorry for my english.

Eclipse Tomcat server does not start

Situation: I installed JRE 8, and configured Tomcat 8.5 on my Eclipse Neon.3 Release (4.6.3).
Problem : I added a project and the server console shows server start-up in 41935 ms. But the background process keeps showing "Starting...." This is shown in the ScreenShot below.
Later, the server stops because it times out. Please help me resolve this.
I don't know how this worked, but merely restarting the PC and cleaning Eclipse's Tomcat server solved this issue.
Also, if at any point of time there is a Security alert asking permission to allow Java to access Public or Private networks, check all the boxes.
This can happen if already an instance of Tomcat server is running on the port(default is 8080). Kindly run below command in command prompt
netstat -ano
to list down the list of process and the port they acquire that are running currently and see if there a process running on the Port that your tomcat server is trying to acquire.
If yes, kill it and run the server again
had the same problem with Tomcat 7 (Liferay server), seems to be a compatibility bug in eclipse, I had to change to a lower version of eclipse.

Can't run Java EE project through WildFly 10

When I unzip the wildfly-10.1.0.Final.zip file on my computer at home. Then WildFly starts running automatically. I had verified this through going to localhost:8080. Because of this I can't run my Java EE project on Netbeans (I have added WildFly as server in Netbeans). In the logs I see:
Address localhost: 8080 is already in use
I also can't shutdown WildFly through the following command:
$ ./jboss-cli.sh --connect command=:shutdown
However I can shutdown WildFly by killing his process. But this still doesn't fixed my issue on Netbeans. Because I still get to see: Address localhost: 8080 is already in use.
At my work when I had unzipped the wildfly-10.1.0.Final.zip file. It didn't start automatically I also had no problems with running my project on WildFly. And I also can shutdown WildFly through the command line or Netbeans.
Anyone that maybe knows how I can fix my WildFly server problem on my computer at home?
Which version of NetBeans are you using ? Until 8.2 WildFly 10 isn't correctly identified.
You may try NetBeans 8.2 RC1 from https://netbeans.org/community/releases/82/ or a nightly build as this would fix your issue.
NetBeans checks if there the instance is already running before trying to start it, so you don't have to start it beforehand but you can :)

IntelliJ, can't start simple web application: Unable to ping server at localhost:1099

I'm trying to make a simple web app in IntelliJ by following this tutorial:
http://wiki.jetbrains.net/intellij/Creating_a_simple_Web_application_for_Tomcat_in_IntelliJ_IDEA_12
I believe my Tomcat is installed correctly since I see the tomcat pictures when I go to
http://localhost:8080/
I've followed all the steps up until the part it tells me to run index.jsp, at which point I get the error:
Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: nodename nor servname provided, or not known
I see this in the log:
Application Server was not connected before run configuration stop, reason:
Unable to ping server at localhost:1099
This 1099 comes from the JMX port in Run -> Edit Configurations.
How do I fix this?
To fix this you need add your machine name in the /etc/hosts file to point to localhost(127.0.0.1).
You can find your machine name by running the following command:
$ hostname
macbook-pro
From the output above you know your hostname is "macbook-pro".
Edit "/etc/hosts" file and add that name at the end of line that lists 127.0.0.1
127.0.0.1 localhost macbook-pro
Save the file.
Now you IntelliJ should be able to start your server.
See that the tomcat you are using is compatible with the Java version. For me the issue was Tomcat-9 required Java-8. If you have a older version of Java, you could use Tomcat-7 to test.
I added my hostname to /etc/hosts on localhost.
Added JAVA_HOME
but still it showed the same error. In the console, there was output:
Unable to start as CATALINA_BASE contains a colon (:) character
I solved the problem by going to Edit configurations -> Startup/Connection -> changing CATALINA_BASE value to the tomcat installation folder. Before that, it was
CATALINA_BASE: C:\Program Files\Apache Software Foundation\Tomcat 8.0
which can't be correct on a linux machine ;)
For those who encounter this when you just recently updated IntelliJ (In my case 2019.2).
I am using JBoss server so i tried to run standalone.bat in the command line and I saw the real issue on the console.
It can be different to yours, but in my case I saw:
failure description: "WFLYSRV0137: No deployment content with
And on that error I was able to fix this by removing the items (war or ear) inside the <deployments/> node in my standalone.xml
Hope this helps for those using JBoss+IntelliJ
FYI Under certain network conditions your hostname may change or be incorrect. If you are on a mac the following will let you set your hostname fairly permanently:
sudo scutil --set HostName correct-name
This appears to be a problem with the way mac is handling reading the /etc/hosts file. See for example http://youtrack.jetbrains.com/issue/IDEA-96865
Adding the hostname to the hosts file as bond described should not be required, but it does solve the problem.
My problem was that tomcat 8 and higher are not compatible with java 6. Changing to java 7 solved it.
I had similar issue when I entered very big port here:
But when I corrected it to something smaller which is in offset range:
Issue was resolved.
I had same problem. In "Edit Configurations.." -> "Tomcat Server" I changed JRE from "Default" to my current version with SDK directory address (like C:\Program Files\Java\jdk1.8.0_121\jre)
My Tomcat version is 8.5.31
This error came to me when I configured (wrong) 3 Gb memory where there was none. IntelliJ does shows the real error message (Could not reserve enough space for object heap) in the Output frame.
I was confused, and attracted by the message in the Event Log, which is to be ignored in this case.
None of the answers above worked for me. In the end I figured out it was an configuration error (I used the android SDK and not Java SDK for compilation).
Got to
[Right Click on Project] --> Open Module Settings --> Module --> [Dependendecies] and make sure you have configured and selected the Java SDK (not the android java sdk)
I meet this question when i use intellij 15.0,then i update to 15.02 version. after that, I edit configurations and reset the Default JRE to my own JRE.It works well for me;
I added the following VM Options and it worked for me:
-Dcom.sun.management.jmxremote=
-Dcom.sun.management.jmxremote.port=1099
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
I solve this problem adding the environment variables JAVA_HOME(C:\Program Files\Java\jdkx.x.x_xx) and JRE_HOME.
I had the same problem of "Unable to ping server at localhost:1099" while I was using intellij 2016 version.
However, as soon as I upgraded it to 2017 version(Ultimate 2017.1) which is installed using "ideaIU-2017.1.exe" the problem disappeared.
I had this issue when running Tomcat 6.0.53 on Mac OS Sierra with Intellij IDEA to deploy Spring projects.
This problem was solved after changing the Tomcat version to the 'tar.gz' one from official site. It seems the 'zip' one is for windows.
Setting project's SDK in IntelliJ (File > Project Structure > Project:Project SDK) worked for me
If your tomcat contains file setenv.sh ([YOUR_CATALINA_HOME]/bin/setenv.sh) it may redefine the JAVA_OPTS variable that JIdea uses to set up JMX, so you have to add them there:
export JAVA_OPTS ="$JAVA_OPTS <whatever was in setenv.sh>"
echo $JAVA_OPTS
Below is the error I observed :
to resolve, in my case, I exit intelliJ and renamed folder ".idea" to ".idea_old" (so that I don't loose old config) and restarted intelliJ, It created a new ".idea" folder and I provided new tomcat configuration. On running tomcat this issue was removed.
On top pointing my hostname to 127.0.0.1 in hosts (just run hostname in cmd to get it) as well as doing what David GC mentioned, for me the error cleared and debugging worked when I went into the tomcat configuration and changed the debugging startup script from startup.bat (which was just my monkeying around) back to the catalina.bat start default.
I had same issue and my mistake was, I was trying to start tomcat server with incompatible version of JDK and installed Apache tomcat server. In my case I had installed JDK 7 with Apache tomcat 9. For Apache 9 JDK should be >= 8.
For compatibility check this https://tomcat.apache.org/whichversion.html
For me, it was a much different solution since it was running on a virtualbox, so I had to edit the hosts file and add the virtualbox as a localhost
127.0.0.1 VirtualBox-blahblah
In windows environment just check the PATH environment variable if Oracle JRE runtime refreshed the path and put himself at the very beginning of the path. In this case even if the JAVA_HOME AND JRE_HOME points to the correct JDK, the JRE will have precedence. And this case IntelliJ will not start Tomcat instance with the mentioned error message.
If you are using java 7 then make sure you have Tomcat 7
brew install tomcat#7
and update run configuration to Tomcat 7
Tomcat 9 is working with java 8
I'm leaving an answer for the jboss user.
If any of the people experiencing this error are using jboss, make sure the JBOSS_HOME location is correct.
If we have the installed the compatible tomcat version for the application JAVA jdk version, we can resolve this issue easily.
In my case, when I am using Tomcat 10.1.0.M4 with JAVA JDK 1.8 I faced this issue. When I downgrade my tomcat version to 9.0.41, the issue resolved for me.
You can find the compatible tomcat version for the JAVA JDK here..

Tomcat6 won't start on Windows and Java6

I just downloaded a fresh copy of Tomcat6 to install on a development server. The server is running Win2k3 SP2 and Java6.
When I go to start Tomcat6 it reports the following:
D:\>d:\tomcat\bin\tomcat6.exe //TS/Tomcat6
[2009-07-14 15:26:38] [427 prunsrv.c] [error] The operation completed successfully.
[2009-07-14 15:26:38] [1336 prunsrv.c] [error] Load configuration failed
It seems like Tomcat is having config issues, but I'm not sure where to start looking. It's a bit surprising that Tomcat had this problem right out of the box. Is there any compatability problem between Java6 and Tomcat6? Why might the default config be failing?
Just curious if your CATALINA_HOME and JAVA_HOME set? Those environment variables are prerequisite to run Tomcat. Go to Start-->My Computer (right click on it) -->Properties-->Advanced-->Environment Variables (button) and then set CATALINA_HOME to the path of your Tomcat and JAVA_HOME to the location of your JDK, also add JAVA_HOME\bin to your PATH variable.
Ok, Solved this one myself. It turns out that "Load configuration failed" was a red herring. This was caused by Tomcat being unable to load java. I discovered this in $CATALINA_HOME\logs\jakarta_service_YYYMMDD.log.
I solved the problem by following these instructions. Which basically amounts to copying msvcr71.dll to c:\windows\system32
What would the //TS/Tomcat6 argument do?
The simplest way to make this work outside an IDE is to install it as a Windows Service and us the Monitor TOmcat application to stop and start it.
