Slim Application Error A Website Error Has Occurred. Sorry For The Temporary Inconvenience.
vote 2 down vote favorite I'm developing an application with RESTEasy and JBOSS 5.1. For specific situations, I have to return 404 error (not found). In the sources, I'm using import org.jboss.resteasy.spi.NotFoundException; throw new NotFoundException(...); The problem is that, in the header response, I have Status Code: 500 internal server error even if in the body the exception is: org.jboss.resteasy.spi.UnhandledException: org.jboss.resteasy.spi.NotFoundException This is a normal behavior? It's

not possible to return Status Code: 404? exception jboss resteasy share|improve this question edited Dec 21 '11 at 10:12 Barry Kaye 6,31852349 asked Dec 21 '11 at 10:05 ovi2ut 57117 Finally, I think it was just a configuration/dependencies issue. Now it's working OK (so, it is possible to throw NotFoundException). –ovi2ut Jan 9 '12 at 8:17 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote accepted I encounter some problem. I found the root cause. The built-in exception handle is only occur in resteasy newest version build 2.3.1 GA. If you upgrade to this version.You can get the expected result. share|improve this answer answered Apr 15 '12 at 7:13 jiafu 1,76042245 add a comment| up vote 2 down vote It does seem a bit strange that RestEASY does not handle the NotFoundException out of the box. It should, according to the docs: Resteasy has a set of built-in exceptions that are thrown by it when it encounters errors during dispatching or marshalling. Anyways, you can work around it by adding an ExceptionMapper: import org.jboss.resteasy.core.Dispatcher; import org.jboss.resteasy.mock.MockDispatcherFactory; import org.jboss.resteasy.mock.MockHttpRequest; import org.jboss.resteasy.mock.MockHttpResponse; import org.jboss.resteasy.spi.NotFoundException; import org.junit.Assert; import org.junit.Test; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.core.Respon

CakePHP uses exceptions internally to indicate logic errors or misuse. All of the exceptions CakePHP raises extend CakeException, and there are class/task specific exceptions that extend this base class. CakePHP also provides a number of http://book.cakephp.org/2.0/en/development/exceptions.html exception classes that you can use for HTTP errors. See the section on Built-in Exceptions for CakePHP for more information. Exception configuration¶ There are a few keys available for configuring exceptions: Configure::write('Exception', array( 'handler' => 'ErrorHandler::handleException', 'renderer' => 'ExceptionRenderer', 'log' => true )); handler - callback - The callback to handle exceptions. You can set this to any callback type, including anonymous functions. renderer - string - The class responsible for rendering uncaught exceptions. If you choose a custom class you should place the file for that class in app/Lib/Error. This class needs to implement a render() method. log - boolean - When true, exceptions + their stack traces will be logged to CakeLog. consoleHandler - callback - The callback used to handle exceptions, in a console context. If undefined, CakePHP's default handler will be used. Exception rendering by default displays an HTML page, you can customize either the handler or the renderer by changing the settings. Changing the handler, allows you to take full control over the exception handling process, while changing the renderer allows
startup; systemnotbound; page not found Technote (troubleshooting) Problem(Abstract) HTTP error - 500:system#not bound exception is received when trying to bring up the login page Cause The Maximo application has not http://www-01.ibm.com/support/docview.wss?uid=swg21433828 started Diagnosing the problem Review the Maximo and application server logs for Maximo startup error http://flask.pocoo.org/docs/latest/patterns/errorpages/ Resolving the problem The WebSphere or WebLogic console show that the Maximo Server is running and also the Maximo application is running. From the application server level everything starts fine. The issue is the Maximo application has not started/initialized successfully. If the Maximo root logger logging level is at INFO or above (INFO is the default) the error 500 Maximo startup will be logged. WebSphere Open the systemout.log file for the Maximo Application Server. For example ibm\websphere\appserver\profiles\ctpappsrv01\logs\mxserver\systemout.log Search for the text 'Maximo is ready for client connections'. This means the Maximo application has started successfully and you should be able to connect and login. If that text is not in the log, search for the text ' Maximo failed to start'. If Maximo failed to start there will probably also error 500 system# be an error message. That error is the root cause of the Maximo startup. Address the error and restart the Maximo Application Server. WebLogic If running from a command prompt, the startup will be in that command prompt window. If running from a service, open the maximo.log file for the Maximo Application Server. If the maximo.log is not configured to be created, start the Maximo Server from a command prompt so you can see the startup logging. Search for the text 'Maximo is ready for client connections'. This means the Maximo application has started successfully and you should be able to connect and login. If that text is not in the log, search for the text ' Maximo failed to start'. If Maximo failed to start there will probably also be an error message. That error is the root cause of the Maximo startup. Address the error and restart the Maximo Application Server.

will also provide a plain black and white error page for you with a basic description, but nothing fancy. Depending on the error code it is less or more likely for the user to actually see such an error. Common Error Codes¶ The following error codes are some that are often displayed to the user, even if the application behaves correctly: 404 Not Found The good old "chap, you made a mistake typing that URL" message. So common that even novices to the internet know that 404 means: damn, the thing I was looking for is not there. It's a very good idea to make sure there is actually something useful on a 404 page, at least a link back to the index. 403 Forbidden If you have some kind of access control on your website, you will have to send a 403 code for disallowed resources. So make sure the user is not lost when they try to access a forbidden resource. 410 Gone Did you know that there the "404 Not Found" has a brother named "410 Gone"? Few people actually implement that, but the idea is that resources that previously existed and got deleted answer with 410 instead of 404. If you are not deleting documents permanently from the database but just mark them as deleted, do the user a favour and use the 410 code instead and display a message that what they were looking for was deleted for all eternity. 500 Internal Server Error Usually happens on programming errors or if the server is overloaded. A terribly good idea is to have a nice page there, because your application will fail sooner or later (see also: Application Errors). Error Handlers¶ An error handler is a function, just like a view function, but it is called when an error happens and is passed that error. The error is most likely a HTTPException, but in one case it can be a different error: a handler for internal server errors will be passed other exception instances as well if they are uncaught. An error handler is registered with the errorhandler() decorator and the error code of the exception. Keep in mind that Flask will not set the error code for you, so make sure to also provide the HTTP status code when returning a response. Please note that if you add an error handler for "500 Internal Server Error", Flask will not trigger it if it's running in Debug mode. Here an exa
