I am trying to run a sample program in spring tool suite. I am not able to run the Pivotal server and am getting the error message shown in the attached image.
Please can someone provide some suggestions to help.
Thanks in advance.
After many weeks of frustration with this I think the answer is even easier than I thought. My workaround was to keep installing a new server every time this happens. Needless to say this clutters my workspace with many servers and wastes time.
Turns out that the darn server folder say Server7 or whatever server you are using in your STS MUST BE OPEN!!! This may seem obvious but as I open and close different projects I am working on I always click on "close unrelated projects". Well this also closes the Server folder on my workspace! I think the problem is just this simple. Now to talk to the STS people to see if we can make the server intelligent enough to auto open the folder when we click start if it is not already open because I do appreciate being able to "close all unrelated projects" often. Hope this saves some people some frustration.
Also double click your server in server view. In the overview page make sure server configuration points to the directory of the server you are using. In my example it would be Server9. You will notice that if this Server folder is closed in package explorer it will not even be an option to choose. This is when the light bulb went off for me why it could not find the server-config file. See illustrated picture for guidance
.
ps. I finally found my Skitch for Linux alternative = Hotshots
UPDATE: to keep the server from closing when I click "close unrelated projects" simply right click the project and choose properties/project references then put a check mark next to the associated server of this project. Then when you click "close unrelated projects" the server will remain open.
This is due to that fact that server project might be closed. Please keep that open before performing deployment.
delete the server and reinstall pivotal server or install tomcat 7.0 or tomcat 8.0. Tomcat is better option as the error logging better and less cache problem

first of all I am sorry on my English.
I have a problem in my Gwt application.
I build Gwt application and I work on application every day
Yesterday I want to still work on my application but is stopped worked and i do not know why and I not get errors
The application compiled and I get the Url to run on browser
I copy the Url to my Firefox browser and not happened nothing.
I put break point in my entry point class and I see the application not arrived to entry point and I do not know why.
I try to open new project to check maybe the problem in eclipse or in Gwt plug in but the new project worked excellent so I understand the problem in specific this project.
I need help
thank you everyone
Okay i have 3 possible suspicions:
You updated your Application, but for some reason some JavaScript stayed inside the Firefox cache. Solution: Go to options and "Clean cache" and always try to press CTRL+F5 instead of just reloading, this will clean the current website's cache saved in your Browser.
Your HDD is full(less likely). You said you work everyday on the app. The caching in dev-mode is very VERY bad(for me it once contained 300GB of cached data). there is a folder called <win_user>/AppData/Local/Temp - delete everything inside if you find a lot of "gwt-<something>" files and check the folder's size. There is nothing valuable inside it(if you didn't place anything inside :D)
P.S. Turns out it was a Firefox Memory-leak that has been fixed in GWT 2.6.0 :)
Your Eclipse messed up some random stuff. As always - Project > Clean...
Then right click on app and let gwt recomile your app(if you have an ant file that uses the gwt-compiler, execute that)
I can't really think of anything else...
The only thing that could be is that YOU changed something, but you said you didn't so...
Hopefully it works,

Beside my project name says [Desktop NO-HEAD] in eclipse. I am developing an android application, and was wondering if there is anything wrong with this, why it might be saying that, and if it makes a difference to anything, though everything seems to compile and debug normally. Surprisingly, I have found literally nothing online about this. I was just wondering if anybody knew, thanks!
You apparently have some type of version control going on. Right click on yoir project and go to Team. If you don't want to see it and/or don't want to have any version control at the moment there should be an option somewhere there in Team to disconnect.
In my case, for git, in Eclipse Team settings, I had to Disconnect and then Share Project (Right-click project -> Team -> Disconnect / Share Project...) with the following settings:
Checking any other permutation of those check boxes caused the NO-HEAD for me.
So, nothing has changed with my setup over the past week. I have recently upgraded to Lion, but I have run this application several times since I have done that.
Today, I click the "Run Main Project" arrow in NetBeans 6.8, and I get a dialog box I have never seen before...
I have absolutely no idea what to do. I can find no reference to this error in Google.
Steps I have taken:
Reviewed the logs (nothing unusual up to the point where NetBeans freaks out.
Reverted to a backup Netbeans installation (no change in behavior)
Attempted to change the username/login information to the administrative Glassfish panel (no change in behavior)
Removed the .netbeans directory from my home, and restored to a known good offsite backup.
I have absolutely no idea what "8228 8228 8228" means.
One thing important to note is that Glassfish is running and the creds that I have supplied to NetBeans do work. I can log into the running Glassfish admin panel with them.
Any suggestions at all?
Leaving this here for anyone who happens to run into the same problem.
I would wager that this affects all versions of NetBeans.
I am not entirely sure what caused the original issue, but it appears that NetBeans attempted to "auto-discover" a proxy that I had installed on my system. (GlimmerBlocker, for blocking ads, among other things)
When it did this, Glimmerblocker did not report its IP address correctly (or NetBeans interpreted it incorrectly), resulting in something that looked like:
127.0.0.1
127.0.0.1:8228
8228
8228
Well, needless to say, when the Java NumberFormatter got a hold of that, it didn't like it one bit.
Setting NetBeans to "No Proxy" in it's settings, and restoring from backup again (to undo all the troubleshooting damage I had done) took care of the problem.
Again, leaving this only in the hopes that it helps at least one other problem who may run into something similar.
Say for example I open the file 'Main.html' under 'Web Pages' and change the title from 'Main Page' to 'Main Page - TEST', when I save/run the project it still loads with the title as 'Main Page'.
I have tried a Clean and Build, restarting the server (GlassFish Server v3), undeploying and redeploying, and closing and re-opening the project, however none of these seem to have any affect.
The above seems to be the most that I can narrow it down, I have found more recently that if I restart my computer (which also plays the role of the server) then it will update the changes and everything is happy, however I don't want to have to restart my computer all the time and would much prefer if someone knew what might be wrong and was able to provide a quicker way.
Try: Clearing cache and cookies of the browser.
I am working on a demo for a client of what's possible with GWT-Ext for GWT. After browsing for the simplest way to get up and running, I decided on installing the Google Plugin for Eclipse and using the New Web Application Wizard.
First time around, I followed these steps for create the default application:
Selected File > New > Web Application Project from the Eclipse menu.
In the New Web Application Project wizard, entered a name for the project (ExtDemo) and a java package name, com.extdemo.
Unchecked the "Use Google App Engine" check box.
Clicked Finish.
Right clicked it in package explorer and selected Run As > Run Configurations
Put a check in the Automatically Select Unused Port checkbox.
Clicked Run to see the default GWT 1.7 application
This worked fine... it launched GWT's hosted browser and the app worked as supposed to.
(I then continued to import GWT-Ext and add all sorts of widgets building up a nice little demo app)
However at some point when relaunching the app in hosted mode, the hosted browser displays an empty iframe. I even reverted the code to a point where everything was working as supposed to and... same thing, an empty iframe with the surrounding static content.
Now what is really strange is when I go through the process of creating the default application again by following the steps above, the hosted browser launches with an empty iframe again.
However when I click on Compile/Browse, this sometimes allows the app to launch in Firefox.
Anyone have this happen to them?
I have seen some odd behaviors occasionally. Here are some basic suggestions (some are dumb and you might have tried them already):
Use a new workspace
I do not know if GWT plugin somehow caches stuff in the embedded Jetty. If you are re-creating the default app/project, try and use a different name for the project.
Try and re-use a fixed port so that there is no possibility of having multiple servers running.
Update: Found a new "classic" solution:
Delete the cache in IE and possibly Firefox too. Apparently the 'script' tag content tends to be cached by IE. If this works, we can all try tearing our hair out!
Found the updated answer at this link:
I have had the same problem in the past and found it is much more likely to happen if limited CPU is available. For example if my older laptop was running on battery and had stepped down the CPU speed to save power it frequently happened. When running on mains in max performance mode it only happened occasionally. Now I have a much newer and more powerful laptop and the problem has gone away.
Another cause I found was too many breakpoints set up in eclipse and removing breakpoints would often clear the problem.
I've had issues with the browser caching.
Try clearing your browser cache, refresh a few times after a failed load, etc.
You can also try using a different port so the URL is different.
It takes some time to download and run the GWT app, particularly if you are using extra libraries, so wait for a few seconds to see if the app finally loaded.
What makes the app loading to fail randomly is something I don't know yet, but I suspect, as stated by Daniel Vaughan, that is related with a lack of computer resources, CPU, memory, etc.
