I am getting 503 Service Unavailable when call in Mule application... Call is not reaching to HTTP Listener I think and beside of HTTP Listener there is Set Variable... to Set Variable also not reaching call... Till day before yesterday it was working in all work spaces but suddenly it is not reaching to listener when I was trying after putting debug mode. But for other developer is not having any issue and he is able to receive call to Listener and other components. Current configurations everything is good. Can you please suggest what needs to check.
I had the same problem when I added an autodiscovery configuration for my application. Adding this to VM arguments folved my issue.
-Danypoint.platform.gatekeeper=disabled
I faced the same problem.
Everything was working, and suddenly (don't know why) I received the same 503 response.
I tried a lot to figure out what was going on.
Added new listeners and tested existing flows, which all went well.
Only my particular listener with the APIKit was never getting reached anymore.
I also disabled 'the gatekeeper' as suggested in the following article :
API-returns-503-Service-Unavailable-error-to-clients
Run -> Run configurations -> tab Arguments
I exported the project to a deployable archive file, with the checkbox 'only export project sources' selected. Tested this application on different PC's which went well.
Created a new workspace on my PC, imported the file , and the application failed again.
After a few other try & errors, I enabled the 'clear application data' -> 'prompt' selection box, and I disabled the 'APIKit settings' -> 'Show APIKit consol'.
I'm not sure if that consol had something to do with it, but after restarting the application and select YES on Clear application data , it worked well again.
Run configurations
I re-enabled the 'show APIKit consol' again, and it still worked fine.
This should solve your problem as well.
This is basically the same answer as the answer provided by user15476634, but with a visual description, and reasons why this error may occur.
For those who are wondering where to find Clear Application Data, please see below screenshot.
Most usual suspects in these type of issues is corrupted Application data due to following issues:
Trying to open multiple test consoles at a time
Working on huge payload and not enough memory allocated
Accidentally selecting the multiple run configurations and/or debug configurations at once
when you try to re-run the same app while an instance is already
running by disregarding the prompt/warning window (Do you want to stop the running application and start ...?)
For me, I had the same experience, the 503s appeared out of nowhere. Clearing application data did not work for me, setting
-Danypoint.platform.gatekeeper=disabled
did not work for me. I had to remove this xml tag from my global config
<api-gateway:autodiscovery ... />
It happened to me after turning on autodiscovery in order to deploy, so i had to remove these lines (autodiscovery) temporary then test then return these lines back in order to deploy

I work with a web service (SOAP) that is installed on a remote server (Websphere). Since I do not fully understand its operation, I would like to use debugging to understand the code step by step. I want to use the local instance Intellij (ultimate). My problem is that due to little experience I do not know how to do it. I have questions:
to check the operation of WS I want to send queries to the server using SOAPUI. Is there a possibility for me to look at Intellij (using breakpoints) what values are returned at a given stage?
how to connect it all together?
is there a different, better way to check the code?
First, make sure that debug is enabled on your remote server. This can probably be configured in Websphere. Then, in IntelliJ select the "run configurations" dropdown and "Edit Configurations". Hit the "+" and select remote. Set the correct host and port, and click "OK". Then, start the run configuration in debug mode, add some breakpoints and debug away!
I previously did not have any issues with this, as I have been deploying Azure web app from Eclipse with no issue. Usually it takes a few minutes, but currently it is taking forever with no real progress from what I can tell. I have tried restarting Eclipse as well as deleting the Azure app and recreating a new one. None of those work. Are there some settings I need to reset ?
EDIT: Yes it is a Web App created in Azure, and I previously had no trouble deploying at regular intervals. Last time however I wanted to abort the deployment and attempted to do so in Eclipse but it kept running and it seemed to be hanging so I shut down Eclipse and tried to deploy again but instead of taking just a few minutes, now it is stuck at the beginning with no progress.
I then decided to delete the web app, create a new one, and deploy to the new web app from Eclipse, but it is still the same with no progress.
EDIT: Adding Screenshots of the general environment and Azure configuration.
Just summarize for the above comments, the issue seems that Azure WebApp waits timeout to recover or reset for a failed deployment connection, so a suggestion is that trying to restart the Azure WebApp to recover or reset all status of the current instance fastly, or wait awhile then try to reconnect again.
But for some similar cases, if the above action failed, it's necessary for considering some metadata files in the current workspace, a valid way may be to create a new workspace to try to reconnect.
After running app-engine java project multiple times in eclipse, app-engine local server doesn't work. I am getting error "This webpage is not available" in Google chrome. But eclipse console says that "dev App Server is now running". But using dev_appserver.cmd works fine, it is too difficult when developing the project. Any ideas to solve this?
PS: rerunning is done after stopping the current execution of the server.
Choose 'Automatically select an unused port' in debug configuration.
Local server will start every time on different port, but it should solve your problem.
try to change the configuration by "run as" or "debug as" and check server and port no.
Also ensure that in Windows>>preference>>java>>jre a path to jdk (not jre) is selected.
Please provide more details of the problem if it is still there.
I deployed latest jenkins war in tomcatrunning on my W$7 machine.During my first log in i configured something in matrix based security as explained here.After adding a user in the matrix, ia m unable to load the jenkins. The following error stack is shown. For complete stack trace please visit here..
Now, When i go to the login page, i could see the login form. Do we have any default login to proceed ?
Note: as described in that article i don't see create an account tab in the login page. Hence i am unable to proceed.
Stack trace :

Edit:
I have also, redeployed the war.The issue was still there.
So then, i have downloaded the fresh war file from the JenKins site and deployed in the tomcat of xampp. When ever, i navigate to the jenkins app , the Java SE crashes.
It looks like you locked yourself out. Here are the lock picker instructions:
Securing Jenkins
...
Disabling Security
One may accidentally set up security realm / authorization in such a way that you may no longer able to reconfigure Jenkins.
When this happens, you can fix this by the following steps:
Stop Jenkins (the easiest way to do this is to stopthe servlet container.)
Go to $JENKINS_HOME in the file system and find config.xml file.
Open this file in the editor.
Look for the <useSecurity>true</useSecurity> element in this file.
Replace true with false
Remove the elements authorizationStrategy and securityRealm
Start Jenkins
When Jenkins comes back, it will be in an unsecured mode where everyone gets
full access to the system.
If this is still not working, trying renaming or deleting config.xml.
I followed the steps in below source.But still faced the same issue.
https://wiki.jenkins-ci.org/display/JENKINS/Disable+security
Finally, I tried to unistall and install the jenkins in another directory which help me to start working.
Hope it will help some one.
All the above answers are wonderful, but nobody mentions the elephant - which is HOW does one get matrix security to work? I went round and round with this until I happened upon what I think is the answer.
Here's what I did:
Disable security, as above
Go in to the 'configure global security' page
Select matrix security, and immediately enable all for anonymous
Add your users and set their permissions, making sure there is at least one administrator (I assume with all permissions).
Save, and make sure you are now logged in as an administrator.
Go back and turn off all but view permissions on anonymous (or whatever your 'anonymous access rules' are).
Save.
Done.
I believe the trick for getting past the 'Anonymous must have ' error is to be sure you are logged in BEFORE turning off anonymous admin privs.
you can do one thing
stop the jenkins (using tomcat)
go to config.xml present in JENKINS folder.
Look for the <useSecurity>true</useSecurity> element in this file.
Replace true with false.
Remove the elements authorizationStrategy and securityRealm
Start Jenkins
When Jenkins comes back, it's in the unsecured mode where everyone gets full access to the system
Fixed by two simple steps:
Go to Jenkin Home
rename config.xml
Try launch the Jenkin
I am getting a really annoying problem. In my application, whenever i need to change client code, the refresh make the new fix works
However, when editing server code, i need to stop the current application and run again. When the application is big, this takes a little time.
Is there a way to force update the current running server code???

Is there a way to force update the current running server code???
Absolutely! It's not necessary to stop the server when you need to refresh the server side code: In the "Development Mode" view (in Eclipse), click the icon with the two yellow arrows. This application reload is much quicker than a server restart.
If you are using Eclipse run your back-end application in debug mode instead of run mode and that usually gets you a little closer due to its incremental compiler.
Check this out on how to use an external server with GWT http://code.google.com/webtoolkit/doc/latest/DevGuideCompilingAndDebugging.html#How_do_I_use_my_own_server_in_development_mode_instead_of_GWT's
Run your server side code in some other server like tomcat. And start the gwt application in noserver mode. But if you change any rpc related classes in client side you have redeploy the code in tomcat server.
