I have two queries which I am detailing below:
I installed tomcat 7.0 on my ubuntu machine 11.04.
1. .war file not deployed
When I start tomcat through terminal it works fine and I am able to see the tomcat webpage at http://localhost::8080/. After that I try to deploy a war file ps.war which I copy into the webapps folder inside the tomcat installation directory. And then I restart the server but get the same 404 error even when the .war has been extracted to a ps folder by tomcat.
2. Not running through eclipse
when I open it through eclipse then it shows in eclipse console that the server is started and synchronized but does not run any service and give HTTP 404 eroor. Also in this case, When I open a browser window then I get same 404 error at http://localhost::8080//
Please help me put as I am quite stuck at this moment and not able to run the web services any further. Thanks in advance.
#ezile i can understand for the first query that .war file was faulty thats why you were unable to get it through the browser..
but for second query solution how can i accept that making a correct .war file made http://localhost:8080 running in eclipse...
I am asking this question as i am having the same (first and second) difficulty !!
Did you mean to have two colons in your URL before the port number? It's supposed to just be one. http://localhost:8080
Next, in your tomcat installation directory there is a directory called logs which contains a few log files which will provide more information than just the 404 message you see in your browser.
One other thing to check which we've ran into before is case. I have seen a problem with WebContent\WEB-INF being the wrong case (i.e. lower case) and Tomcat not wanting to pick up the war artifacts.
Thanks all for your responses. I solved the problem. For first part there was some problems with my .war file and thats why it was not getting deployed.
For second, after I corrected my war, it automatically started working for eclipse too.
In my case it was because the WAR required a full path.
I had specified localhost:8080/WarFileName
Which didn't work. It was only when I specified
localhost:8080/WarFileName/src/homepage
Which was how the packages were created in the war file, that it worked.

So I installed Apache Tomcat 9 on my computer, and am having trouble configuring and running it on Eclipse Photon. When I start the server through the Monitor Tomcat application, I can open it up to see the appropriate Apache Tomcat Page, however when I try to run it through eclipse, I get an Error 404, as shown on this image:
I tried changing the server location from "use workspace metadata" to "use tomcat installation", as I saw on several websites and videos to correct the exact issue I'm having ("The origin server did not find a current representation for the target resource or is not willing to disclose that one exists."), but when I run the file after saving that configuration, I get the error as shown in this image:
I am not attaching an application to it just yet, I wanted to ensure that the server was running, and I could see the appropriate Apache Tomcat splash page when I try to access localhost:8080, but that isn't happening.
The Monitor Tomcat application deploys a root application to handle '/'. When Eclipse launches Tomcat for you, it does not deploy anything you do not explicitly tell it to, so nothing's there for '/'.

After doing some digging, I discovered that the reason I was receiving those errors was because the entire Tomcat 9.0 file had restricted access, only administrator-level accounts could modify those files. I was able to resolve the issue by going into the file path, right-clicking on the "Tomcat 9.0" folder --> Properties --> Security --> Edit --> Users --> Full Control.
I am getting error while starting apache Tomcat 8.5.8 as a server in Eclipse. It was showing error that installed Tomcat version is 8.5.8 but it is expecting 8.0, below is error:
error while configuring Apache tomcat
After looking in to other threads I came to know about solution for changing the server file at path catalina.jar\org\apache\catalina\util\Serverinfo.properties
Till here I done the change but while saving and came out of RAR file it shows error Error while saving the changes in serverinfo.properties file
I have tried after stoping the tomcat but still it not allow me to save the changes in server file. Please advice.
The error you're getting saving the file is because Tomcat is still running, and it has the jar file open. Windows will not allow you to save changes to a file while some other process has the file open.
First, stop Tomcat, then make your changes to the file and save the jar, and then restart Tomcat.
If it matters, I ran into the same problem with Eclipse incorrectly determining the version of Tomcat. The solution was to change that "server.info" property in the given file. For instance, if the Tomcat version you have is 8.5.8, you have to change the version to 8.0.5.8.
I'm trying to use Openshift to host my java webapps. The problem I am running into is every time I go to my application "http://omniticketmvc-leviliester.rhcloud.com/" it takes me to a "Welcome to your JBossEWS (Apache/Tomcat) application on OpenShift".
I thought maybe it was because my project had some sort of default .war that was being deployed instead of the one I wanted. To try to confirm that I followed this guide made by to deploy a pre-compiled War file. https://www.openshift.com/kb/kb-e1088-how-to-deploy-pre-compiled-java-applications-war-and-ear-files-onto-your-openshift-gear .
As you can imagine that did not work. The guide implies that I should be able to find my webapp running at app-domain.rhcloud.com/mywebsite with "mywebsite" being the name of the war file my project created. In this scenario my Application war file is name "OmniTicket". I can find that war file on the server using ssh but the directory hierarchy is confusing to me.
I also tried looking in logs on the server but I don't see any errors to indicate a malfunction in spring or database connections. Any help would be appreciated. Specifically when I deploy my application to the Jboss Server without any obvious errors, why can't I get to the application root?
I should also mention it is a SpringMVC restful service application that works locally.
Try following steps:
Rename your war name to ROOT.war
Delete the src and pom.xml. If pom.xml is present then OpenShift would try to build the maven project
Place the war in deployments folder under your application root folder
Commit the war and push changes to application Git repository.
Check the logs using rhc tail command
i am facing a problem in using basic authentication..
initially i tried this in eclipse but i got 404 error, i tried everything, restarting, creating new projects but nothing worked.
then i exported the war file n deployed it in apache-tomcat web-app folder and started tomcat from command line and it worked,,
when i go this way i get the expected output when i refresh the page in eclipse , it works.
but then again of i run shutdown.bat and run server in eclipse and again refresh the page.. I GET NOTHING.. SAME 404 ERROR
please help
Check properly that may be you deployed your .jsp file inside WEB-INF folder so you will get this error because WEB-INF is secure.So create .jsp .html inside web-content.
Error 404 means your tomcat not able to get requested resource.
You can go here and check here

I know there are many questions about Apache tomcat 404 error: but I think mine is different.
I am using windows 7 64 bit
unzipped eclipse-jee-juno-SR2-win32-x86_64 to C:\
unzipped apache-tomcat-7.0.37-windows-x64
changed port server.xml to 3030 instead of 8080
continue with this steps "Quick Start" from point (2)
I didn't forget:
copying ROOT folder
R-click tomcat node in eclipse Servers tab -> properties -> Switch location
Double click tomcat node in Project explorer and check use tomcat instillation (takes control of tomcat installation)
The page:http://localhost:3030/ works fine. It shows the message If you're seeing this, you've successfully installed Tomcat. Congratulations!
But when I tried simple project (I followed basic tutorial) and use Run as -> Run on Server the page of error 404 is shown. When back to http://localhost:3030/ it shows no error.
No error with http://localhost:3030/
Error when running a project!

I am The author of this question, and I solved it. I will provide the solution so that others can get help from it.
As I followed this installation steps carefully, then the installation is correct.
The only problem that caused the error is in the web.xml:
- When create a new "Dynamic Web Project" (As my case)
- Take care of this file: WebContent -> WEB-INF -> web.xml
- The <welcome-file> </welcome-file> tags must refer to exist files to display in the browser.
- If there are some default tags delete them.
- when you create for example a new HTML file named index.html, then make sure that the web.xml file refers to it. <welcome-file>index.html</welcome-file>
Digression (irrelevant to the solution above)
I am actually working on NetBeans extensively doing simple Java Standard Edition projects. I rarely encountered problems with NetBeans, and when they occur I can solve them easily either myself or by searching for information about the problem.
When I began learning the Java Entrprise Edition, and see tutorial on NetBeans, I started my first project from the first day.
But I found most of the tutorials use Eclipse and that was the reason why I installed it.
When I moved to Eclipse. I encountered many problems, and each problem take many hours to search and solve. that takes three days before starting one project.
I am wondering why people prefer Eclipse over NetBeans. I think there is some reason. (^_^)
