My tomcat 5.5 start fine when I start it by itself. When I try to start it in eclipse, it times out. It just sits at "Starting Tomcat v5.5...at localhost". I even changed the timeout to 5 minutes and it still won't start. I've tried reinstalling my tomcat in eclipse multiple times and that hasn't helped at all. Please help.
You can specify the timeout in the server configuration screen in Eclipse which you can get by doubleclicking the server entry in the Servers view. You could try to increase it to 100 seconds or something. But I don't think that this will fix the real problem.
You need to ensure that Tomcat which is started externally is completely shutdown before you start it from inside Eclipse. To verify this, go in your webbrowser to the address where Tomcat should be listening on, e.g. http://localhost:8080. If you get a browser default connection timeout error, then it's fine. This way you should be able to start it from inside Eclipse.
If in vain, you could try to clean the Tomcat working directory by rightclicking the server entry and choosing Clean. If still in vain, try restarting Eclipse as eclipse.exe -clean.
After days of messing with this, I finally figured out that it was a specific project that I had added to the server. It somehow caused the server to never start. When I switched the jdk from the workbench default, to version 6 which I downloaded, it worked fine. I'm still not exactly sure if there is a jar in that project that is causing the problem.
I know it's an old post but I had the same problem when I updated to eclipse indigo and the problem was fixed when I changed JDK version to 1.6.0_36.
In my case (kepler) switching between jdks didn't work, but putting just one webapp at a time (when debugging) did the trick.

Hi guys im using intellij and maven and i was working on my code but when I try to ru it locally im getting this issue, I checked all the configuration but I dont know exactly why this issue appear
This happens when IDE can not connect to mentioned port. It is most likely specified in run debug configuration. This may happen because the port has already been occupied by another process (e.g. There is already Tomcat instance running).
Also if you have antivirus/firewall make sure it does not block IDE process from making connections on localhost: make sure to exclude IDE process, IDE installation home, IDE configuration/system folders, project and library directories from the scan. Try restarting the PC, try using different JMX port in Run/Debug Configuration.
I just updated to MyEclipse 2016, and I am having some issues getting my code to debug.
I wrote some changes in a java file and am trying to debug them on my websphere application server, but I noticed the debugger wasn't following the code at all. After a little investigation it turns out that I'm on V5 of the code, but the debugger is running V4 of the code.
I've tried going into the menu at
Run -> Debug Configurations... -> (Select My Server) -> Source
and changing the sources listed in here to just the workspace projects, but the debugger still goes through the old version of the code.
I'm at a loss and don't know what to do to get the debugger to pick up the right code. Does anybody have any suggestions I could try to get my debugger to pick up the new version of my code?
Edit: Forgot to include, Project --> Build Automatically is checked in the menus, and I have tried manually cleaning this a few times myself as well.
From your last comment, this means that the V4 code is actually executing on the server. The debugger is not executing anything; it is the server that is executing the code. So you have the wrong version deployed, somehow. Try a clean on the server, to remove any deployments and then re-deploy your project.
Given what everybody had said I checked into the deployment to the server. Looks like I had a WAR deployed to my server, when there is actually an EAR I can deploy to the server which includes the WAR I had deployed. Apparently doing just the WAR broke things, but deploying the EAR seemed to fix it all. Thank you all for the input though, definitely helped me get to the root of the issue!
I have just downloaded NetBeans 7.3 for JavaEE and installed it with Tomcat 7.0.41 Everything went fine and I can run NetBeans, start and stop Tomcat from within the IDE and add and remove servers at will.
However when I try and create a Java web Application project my server list is empty.
The message I get at the bottom of the wizard for creating projects is "No servers are registered in the IDE. To register a server, click the "Add..." button.
I have Googled and got nothing and looked at the NetBeans docs and got nothing, help me
I am running Netbeans 7.3, Java 1.7, Tomcat 7.0.41 and Windows xp-3.
This Problem is solved by just Restarted Netbeans Software
Thanks to all
I know the original problem was solved, but I had a very similar issue, and in my case simply restarting Netbeans did not help, so I wanted to help anyone with my issue. It sounds stupid, but I wanted to warn people that they need to be sure to download the right tomcat zip file.
Tomcat lists several zip files on their server, and I should have been using the Windows-64 zip file. Instead, I downloaded the first file, which just said "zip". I am not sure what configuration this was. It ran in windows 7, but created the same sort of mysterious pattern in Netbeans. In the Services tab, I could clearly see Apache Tomcat listed under Servers. If I started the service it worked fine. However, when I right clicked on my project and attempted to resolve missing server problem, it would not list tomcat in the list. The list is filtered to only show servers that are valid with the version of Java EE 6 or whatever you are using. In my case, apparently the original tomcat I downloaded was not valid.
You have to register the server inside Netbeans.
Simply a matter of going to the servers tab under tools & adding a new server & browsing to the installation location.
Follow the tutorial on the link below here (start at the time I have set):
Tutorial
Try this remove all server from the IDE and then double click the netbeans exe go to customize select the the tomcat server alone and then install
sample
Go to Tools -> Plugin -> Update Plugin.Worked for me, give it a try.
This is more for reference than anything but i kept hitting my head against the wall for the last few nights.
I kept getting the CONNECTION RESET error back from maven when trying to use FTP to deploy files to an external repo.
All the maven settings were set up correctly.
I eventually decided to try the POM file on my other dev computer and it worked.
This then caused me to look through the setup of the systems, and i realised that my laptop was using JDK1.7 whereas my main computer was using JDK1.6.0r31
If you encounter the same issue trying to deploy your files through FTP (might occur on anything really) then make sure you try JDK1.6.
If you are running Windows 7, could this bug have something to do with it?
Try using the -Djava.net.preferIPv4Stack=true option when running Java with Windows 7 and see if this fixes the problem.
I have a Tomcat application which, the first time I start Tomcat after starting Eclipse, I get an odd NoClassDefFoundError. If I then stop and restart Tomcat through Eclipse, it works fine. I have single, double, and triple checked the classpath and everything seems fine. Anyone ever seen anything like this before?
relevant versions:
Tomcat 5.5.17
eclipse 3.3 europa
tomcat plug-in for eclipse by sysdeo:
com.sysdeo.eclipse.tomcat_3.2.1
I notice that this is a pretty old version of Tomcat, that might be contributing to the problem. You could try the following
Start Eclipse.
Clean your webapp project (build if automatic build is off)
Start the Tomcat server.
That's the only thing I can think of. Other than that I would recommend getting the latest 5.5 version of tomcat (I think it is 5.5.25)
I had problems like these as well, I think I solved it by linking in a whole folder of classes, a different folder though, there were copies of the libraries in a few places, and the Tomcat server needs the libraries from it's runtime imported into the project.
I've found the tomcat plugin to be generally buggy, and have stopped using it.
In my consulting job, I worked with a team that had all manner of stability issues with their application in development. Removing the tomcat plugin, and just having them start/stop tomcat from the command-line fixed all of the issues.
What is the class that is missing?
Have you trying starting and stopping tomcat with wtp instead of sysdeo?
Nope, never saw it. It is very unlikely that the class is present and that it is a classloader problem.
What is the class that is missing. It is probably that it is occasionally going through some error condition
e.g. trying to open a port that is already open
and the error is causing it to try and load this specific class
