I am new to intelije and I had a maven project in Eclpse which worked fine. I migrated to Itellij, I can build project using maven and run it in Tomcat server 8 and evrythings look fine till I tried to call Webservice using SOAPUI and then i get into the problem , when I call my webservice?wsdl or try to send a request using SOAPUI, I see nothing ! just a white blankpage .... no error , no "page not found" ... nothing ? ( jax-ws libraries are loaded by maven)
have you any suggestion for me to solve this problem?
I noticed one more thing and that is, when I open my webapp in two diffrent browses , i can only see in the first browser that I opened, and the other browser shows nothig ( again a whit blank page) It seems that I can run the app only once at the same time. but as I used Eclipse I opened the app at the same time in at least 3 diffrent browsers to compare the GUI at the same time!
thanks in advance for your efforts

I'm working on JSP project in RAD 8.5.5 (when I tried to switch to Eclipse Kepler I've had the same issue) and WebSphere 8.0
When I change something in external JavaScript files which contain my own JavaScript functions I begin to get an error - 'function non defined' or even I lost part of code of this *.js page when I try to debug it in Chrome.
When I publish it to the server or rebuild it doesn't help. When I try to work without javascript cache in Chrome it doesn't work. Only after certain amount of time it begins to work. When I make changes in embedded JavaScript code on JSP page I haven't any problem, only I use my own function in external files.
What can it be? I lost a lot of time on this issue and it's annoying.
Thank you!
To overcome this issue you should do as following:
1.Prevent from browser to cache pages, in Chrome you can do it only developer tools are open : Disabling Chrome cache for website development
2.Perform 'Build project' from Eclipse(RAD). In some difficult case you have to do 'clean' on the server.
3.If you encounter unexpected delay while publishing try to delete all Breakpoints and Expressions from debug perspective.
4.Sometimes your server turning off and on every minutes by itself. To stop such behavior restart it in usual mode and then restart in debug mode.
Hope it will helpful to somebody.
I have an Eclipse workspace with a Web App (lets call it MyApp), and Tomcat server. When I run MyApp, Tomcat finds default.jsp and the opening page displays
http://localhost:8080/MyApp/Default.jsp?ActionPage=dashboard
- all fine and dandy.
This web page shows a menu. I choose a menu option from this page which should render
http://localhost:8080/MyApp/config.jsp,
and I get a HTTP Status 404 - /config.jsp ... ie it is looking for the page at
http://localhost:8080/config.jsp
and can't find it. Why is it looking there? It seems to have lost its context.
Netbeans doesn't exhibit this behaviour - it works fine. I just don't know where to look for a solution. Is it the Tomcat configuration or the Web App configuration?
All suggestions welcome!
When you choose your menu option, how is the URL called : simple form submit, ajax request?
In any case, you should have a URL looking like /MyApp/... in your code.
You can also check which URLs are effectively called by using a debug tool in your browser (ie Firebug for Firefox)
Another test to do if you use a Tomcat embedded in Eclipse is to start your Tomcat outside from your IDE, just to check the potential behaviour differences.
I'm currently developing a web project running on Tomcat 7 and I cannot see anything who's suppose to be on Tomcat (blank page when I do a HTTP request in my browser).
My Modus Operandi:
I launch a new instance of server in locahost (apache-tomcat-7.0.34) within Eclipse (I work with Indigo and tried with Juno as well)
Tomcat's ROOT folder has been pasted in the 'wtpwebapps' folder of all my servers in my Workspace
I add a simple web project on this server instance and try to access it from a HTTP request and I get a blank page. If I try to run a .html file of this web project on this server, I get a 'HTTP 404 Not Found' Error.
What I tried:
I tried to build the whole configuration from scratch (new Eclipse, new Apache-Tomcat) and I still get the same result. But when I do that from my personal computer at home, everything's working fine!!
I tried to put an old version of my code or a tutorial project, but nothing can be launched (therefore, it must be a configuration issue).
I checked the server.xml and web.xml files and nothing looks suspicious (I can paste them if you want but those are the same than those who worked at home)
The only thing I can think of is that I changed the internet connection (and the IP address) of the computer I'm working on, but I don't think it could make any difference when trying to reach localhost, right?
When I follow the steps of the very good tutorial, I do get a blank page on the 'Run Tomcat' topic, but I don't get the Tomcat welcome page once I copied the ROOT folder into "wtpwebapps".
Does someone have any idea where it could come from?
Ok guys, finally got the solution.
I was about to format my computer when i realize that the port 8009 was actually used by another process.
I thought that's the kind of things who are checked when you launch a Tomcat server within Eclipse but it didn't show any error.
The HTTP request went through the port 80, but as the default AJP port is already in use, Apache could not forward this request to Tomcat, therefore a blank page was returned.
At least that's my understanding of this situation...
Hopefully this may help someone who'd run into a similar situation.
Thanks for your help.
I've been using both eclipse and tomcat for years but have always deployed my web apps externally and never had a problem. Now I'd like to use eclipse to debug my web app and I can't figure out how to make it work. I started by trying to get my existing web app to deploy through eclipse but after hours of trying different things I decided to start fresh. Unfortunately, I didn't get much further. I'm hoping if I can figure out how things work with a fresh webapp I can get things to work on my existing. Sorry, this will be long, but here are the steps I tried on the latest eclipse (Juno):
Installed new version of tomcat 7.0.34 at /usr/java.
In eclipse, used "servers" view to add server, pointing to the new install (I didn't add any resources because there weren't any available yet). Starting the server worked and got a 404 as expected at http://localhost:8080/ ... then I stopped it.
Created a new "dynamic web project", named it TomcatDebug, set the location to ~/tomcat-debug, chose the server just created above (the only one), chose default config, tomcat-debug is empty so chose defaults for build paths, defaults for module settings and had it generate web.xml.
In the "tomcat-debug" folder it creates WebContent, build, and src. I throw a sample "hello, world" index.html into WebContent.
Now the project TomcatDebug is created so I try to run it, tell it to "run on server", and it goes to http://localhost:8080/TomcatDebug/ but gives a 404. I even try to add index.html but it still gives a 404.
This is about as basic as it can possibly get so what did I do wrong?
Continuing to try and figure this out I stop the server, change the server setting to "use tomcat installation", but still get a 404 in the same way when I restart. I tried changing my module context path and still 404.
I'm completely stumped. I believe I followed all the wizards as basically as possible. Where did I go wrong?
Thanks for taking a look.
I haven't run tomcat through eclipse in a while, so can't answer that aspect of the question. But, to get at the heart of what you're trying to do (debug a webapp in eclipse through tomcat), you shouldn't necessarily need to. This may serve you instead:
EDIT: Eh, look here for instructions ("Debugging" section). The below is how I did it (JUNO and TC 7) and has an annoying quirk in point #1.
edit the startup.sh (assuming *NIX/OS X) - the last line will probably be
exec "$PRGDIR"/"$EXECUTABLE" start "$#"
change this to
exec "$PRGDIR"/"$EXECUTABLE" jpda start "$#"
to activate debugging. (there are other ways to do this that may be better - i think tomcat/the VM may pause for listeners before proceeding, so when you aren't debugging this is not ideal)
Create a Debug Configuration in eclipse, under the "Remote Java Application" set. Default port should be fine, and presumably host. Choose your project.
Add sources of relevance to your debugging in the Source tab.
Start server and run your new debug configuration. App should stop at breakpoints you've set.
Right Click your index.html Run As -> Run On Server you will see Tomcat will automatically run the page.
if I deploy my project to the Tomcat server which uses just client side code , it works perfectly.
But if my project has a server side code , for example, a button which uses RPC , when i clicked the button, project does nothing at all. No Warnings, no errors etc. Just does nothing at all.
And also, when I deploy "the default GWT example ( greetings project )" to the Tomcat server, it doesn't work.
( I mean my problem is not related with my project's code )
p.s. : My project works perfectly in the Dev Mode.
Could you help me please?
Let us say, wWhen you run on dev mode, your URL was
localhost:port#/page1.
And that the war file name is happy.
Therefore, when you deploy to Tomcat, the server no longer serves it as localhost:port#/page1.
Your app would now be served as
localhost:port#/happy/page1
In your rpc remote service interface file you would have specified the relative path as "/page1".
However, you have to check your web.xml and make sure the servlets are specified in relative paths as well. Check your web.xml to ensure the servlet paths are not hard-coded to
localhost:port#/page1.
