So I have this web service that I am testing using MS Test and I want to get the original exception class which is InvalidOperationException. However whenever I run my test, the exception that I get is the FaultException class (which is the default exception when consuming a web service). I only get the exception in the message property of the exception.
Below is the exception message that I am getting.
`System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: Invalid Entity\n at BL.Lib.WebService.BLWebServiceImpl.UpdateIDNumber(GetUpdateIDNumberRequest idNumberRequest) in [some file]:line 369\n at SSMWebService.Blacklist.BLWebService.BlacklistUpdateIDNumber(GetUpdateIDNumberRequest request) in [some asmx file]:line 132\n --- End of inner exception stack trace ---
Is there a way to get the InvalidOperationException class from the web service?

I have a java project written using spring-cloud-function and deployed in aws-lambda.
I am trying to return a custom exception with some fields in the exception message body, something like"
{
reason: <exception reason>
code: <error code>
<some other fields>
}
#ExceptionHandler, that is generally used in spring boot doesn't seem to work here.
I can return the exception in the required format by creating a class for building the exception message in required format but in that case the error code will always be 200 since it will not be an exception object per se. Instead it will be my custom error object.
Is there a way I can set this up so that the above required format of exception object is returned and correct error code can be returned too?
Thanks in advance
First, the exception has nothing to do with Spring Boot. It's part of spring-web, so yes it would not work here since s-c-function is a general purpose framework, where the same function could be deployed and triggered via web, streaming, aws-lambda etc. .
Now, yes we had a problem returning JSON error (as you show) or object that represents the same, but that was fixed. So please update s-c-function to 3.2.3.
I am running one MVC application where i found one exception in specific method. I will provide here complete details about it.
I am loading some third party grid control from view. to load it i used below code:
#{Html.RenderAction("MasterGridAction", "MyController");}
Now when i access this report from development then this view load and it hits this action method where i used some piece of code there it is throwing error, To catch the error i used try catch block in the method where in catch section i used below code to throw the actual exception like below:
catch (Exception ex)
{
System.Runtime.ExceptionServices.ExceptionDispatchInfo.Capture(ex).Throw(); throw;
}
When exception get catched it sends this to the Application_Error method in global.asax page where i used below code to find out the actual exception like below:
void Application_Error(object sender, EventArgs e)
{
HttpServerUtility server = HttpContext.Current.Server;
if (server.GetLastError() != null)
{
Exception exception = server.GetLastError();
if (exception.GetBaseException() != null)
{
exception = exception.GetBaseException();
ExceptionType(server, exception);
}
else
{
ExceptionType(server, exception);
}
}
}
In this ExceptionType method i get the exception stack and log to the file using "Log4Net". After logging to the file i could see the exception in notepad like below:
Object reference not set to an instance of an object.
Source File: /MyController/MasterGridAction
Stack Trace:
at 3D.Controllers.MyController.MasterGridAction() in D:\MyUser\3D_MVC\Application\3D_OnlyRelease\3D\Controllers\MyController.cs:line 405
--- End of stack trace from previous location where exception was thrown ---
As we can see in above exception it is clearly shown the line number also where this exception get caught.
But once i host this application in IIS server and access the same page then i could see the logged file
There it shows exception like below:
Exception Message: Object reference not set to an instance of an object.
Stack Trace: at 3D.Controllers.MyController.MasterGridAction()
--- End of stack trace from previous location where exception was thrown ---
As you can see the logged exception of IIS server is not having much information when compare to other exception details.
Am i missing anything there to get the complete exception when host in IIS?
Please suggest.
As you can see the logged exception of IIS server is not having much information when compare to other exception details.
This could be because you don't include the PDB files in production.
It might not be a great idea to include them, since that way one can reverse engineer you app with more precision if they hack your server, but it is up to you to decide. I have seen organizations that include them in their production environments.
Try publishing and deploying on a test environment with and without the PDB files to verify this.

I'm not able to open the stack trace. the log file under domain is empty. pls help
NullPointerException means you are trying to call a non-static method (or an attribute) of an object which is not defined.
Example:
String s = "Foo";
System.out.println(s.length());
This code prints 3, because the length of Foo is 3, and s has been initialized as Foo.
Example with NullPointerException:
String s = null;
System.out.println(s.length());
Here s is null and I try to call the method length(), which is a non-static method. Obviously I will get a NullPointerException: there is no sense to get the length of "nothing" (null).
Nevertheless, you still can call static methods with s:
String s = null;
System.out.println(s.valueOf('a'));
Prints a. Note that it is not a good way to call static methods.
The static method valueOf(char) from the type String should be accessed in a static way
This warning explains you should access valueOf(char) this way:
System.out.println(String.valueOf('a'));
Now I let you find the error in your code because you didn't share it.
Does anybody know how to print full stack trace on the Browser, when a Runtime Exception occurs in MULE..??
When a runtime Exception occurs, MULE throws a 500 Server Error to the client , but shows no details to the client. It prints the whole stack trace in Console or Log Files (like the following) :
Root Exception stack trace:
java.sql.SQLException: Invalid column name
at oracle.jdbc.driver.OracleStatement.getColumnIndex(OracleStatement.java:3677)
at oracle.jdbc.driver.OracleResultSetImpl.findColumn(OracleResultSetImpl.java:2749)
at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:494)
+ 3 more (set debug level logging or '-Dmule.verbose.exceptions=true'
for everything)
Can i show the same stack Trace on the Browser (to the client)..??
And if possible , then also tell me how to switch ON or OFF printing of Stack Trace on Browser..??
(It may be possible that sometime in future , i dont want to show stack trace on browser)
Yes this is possible. I assume you are using a regular HTTP endpoint and this is a REST type service(?) If so, you can simply put a try/catch around the code causing the exception and return whatever text you want.
There are also exception strategies (http://www.mulesoft.org/documentation/display/MULE3USER/Error+Handling) for doing more sophisticated error handling, but it sounds like you are looking for the simple answer above.
If this doesn't answer your question, please provide more info about your mule config and the service that is raising the exception.
There is nothing out of the box in Mule to do that. You have to implement an exception handler that will format the stacktrace in the Message exception payload and return it to the caller.
In your case, the HTTP transport has a particularity that can be found in the HttpMessageReceiver code:
try
{
conn.writeResponse(processRequest(request));
}
catch (Exception e)
{
...
conn.writeResponse(buildFailureResponse(request.getRequestLine().getHttpVersion(), httpStatus, e.getMessage()));
This means that when an exception crops-up to the top level, the creation of the failure message response is not customizable: you get this pretty technical message back and that is all.
I see two options to solve your problem:
sub-class HttpMessageReceiver and make the response message customizable in your version,
drop the HTTP transport in favor of the Jetty one (look at the bookstore example) and customize the response error messages at the web container level.
I have just implemented exception handling for a unique-constraint of a JPA entity. It is working as I want it to, but when triggered dumps the handled exceptions to the container logfile.
A JPA entity is managed by a SLSB (Service Façade). The Service Façade is called from another SLSB, which provides remoting capabilities based on JAX-RS.
In the Service Façade, the EntityManager operations are wrapped in a try-catch-block, detecting the cause of the unique-constraint-violation. It then throws a custom checked ApplicationException.
The REST-Bean catches the ApplicationException and throws a custom unchecked BadRequestException.
An ExceptionMapper outputs the BadRequestException to the remote client.
This is all working well. The part that I don't understand is: the (handled) exceptions get logged in the container's logfile (complete with a long stacktrace):

Is this how it should be? I thought since I handle the exceptions, they wouldn't be dumped to the log?
The exceptions are logged because you have exception logging enabled.
Exceptions get logged by default when your log level is WARNING or greater. If you set your log level to SEVERE or OFF then they will not be logged.
i.e.
"eclipselink.logging.level"="SEVERE"
You can also set the "eclipselink.logging.exceptions"="false" property to disable just exception logging.
See,
http://wiki.eclipse.org/EclipseLink/Examples/JPA/Logging
It's the database layer that does the logging of the exceptions. The time you catch them they are already written to the log.
