How to throw a SOAP exception
Hi,
I have a requirement from customer that when they call the WSDL from their app and the workflow will not get what it should, that it should throw standard SOAP exception.
To give more details on it, they will send for example input string "A" and based on that I will return output string "B" in the process.
Now if they ask for "C" for instance, I need to be able to throw that SOAP exception. Is that possible? The process in workbench consists of simple decision point and set value activity based on route conditions.
Thanks
J.
I am assuming you are wanting something to come back as a SOAP fault element?
Unhandled process exceptions are sent back as faults. So, theoretically, you could write a service component to do nothing but throw an exception. Then you could route your process to call that in specific situations.
As an alternative, I would consider having something like an additional 'status' output variable that always came back in the response which indicated the status of your process.
Good Luck,

Throwing Client Soap Exceptions
I am writing j2ee web services and would like to throw Client soap exceptions when a input validation error occurs. Currently I can throw a soap exception and have the msg= be set to what I would like. I cannot set the faultCode to what I would like.
An example of the kind of errors I am generating.
SOAPException: faultCode=SOAP-ENV:Server; msg=Input SSN is not valid.]
An exmpale of the kind of error I would like to generate.
SOAPException: faultCode=SOAP-ENV:Client; msg=Input SSN is not valid.]
Thank you,
David SchwartzHi ,
The client does not have a hook on the SOAP Fault(or for that matter , the SOAP message ).It only receives the marshalled java objects from the proxy.
You might hack the generated proxy code , and hack further into the Response objects , and the Fault object to create your customized fault .
Thanks

Ssrs report web service to save report as pdf throws error Soap exception unhandeled by user code
I am creating a C# web application to save an SSRS report as a pdf file on my local machine.
I added the ReportService web reference as RS2005 and ReportExecution2005 web reference as RE2005.
http://myServer/ReportServer_DEVPROJECT/ReportExecution2005.asmx?WSDL
http://myServer/ReportServer_DEVPROJECT/ReportService2005.asmx?WSDL
I created the following function SaveReport that is called on button click. My report can be accessed on the report server with the following url:
http://myServer/Reports_DEVPROJECT/Pages/Report.aspx?ItemPath=%2fData+Mgmt%2fSample+Letter
On the Report Manager home page the report link appears as "SAMPLE LETTER".
It is deployed in the DataMgmt folder on the Report Manager.
It uses a data source called "DS Letter" with option "Credentials stored securely in the report server"
My application gets compiled, but I get the following run time error:
Error: Soap exception unhandeled by user code. The item '/DataMgmt/Sample Letter' cannot be found. ---> Microsoft.ReportingService
s.Diagnostics.Utilities.ItemNotFoundException: The item '/DataMgmt/Sample Letter' cannot be found.
Please check my code and let me know what I can do to run this successfully. Once this is done, I would like to get help with passing a parameter (memberID) to the generate report for that member, through this application.
Thank You in advance for your help.

SaveReport();Hello Devster,
Thank you to post your question on TechNet forum.
After reviewing the whole post, I have a question to you. You can access the report via the link, http://myServer/Reports_DEVPROJECT/Pages/Report.aspx?ItemPath=%2fData+Mgmt%2fSample+Letter.
From the URL, I can see that the report is located at: /Data Mgmt/Sample Letter, instead of /DataMgmt/Sample Letter. In addition, I found that the target report is "/DataMgmt/Sample HAP Letter" instead of "/DataMgmt/Sample Letter" as the error described. I
am not sure whether you post out the correct code segment.
Please check the above things on your side, and hope it is helpful to you.

How to throw a permanent exception during mapping?
I'm using the java coding: "throw new RuntimeException(message);" to trigger an error during mapping.
This will set the message status to: "System error, manual restart possible".
How can I throw a permanent exception during mapping? So that the message is set to error but will NOT be restartable.Hi,
Any error in asynchronous mode in XI will be in a Restart Mode. I dont think this can be done.

Throw Soap Exception in BPM.
Hi All,
My scenario is Soap->XI->BPM->RFC. I get a soap request in synchronous way with Request and Response messages I Map my request to a RFC and If there's any application error or mapping error I have to send SOAP fault exception to my Soap Sending system. But I don't see any option in BPM to throw soap exception only thing I can do is to map my errors in the soap response and send it to soap sender.
But my Soap sending system needs soap fault not a response message when any errors happen.
Please let me know if anybody has this same situation and how to handle it.
Thanks in Advance,
SP.Hi VJ,
I have to use BPM as I am doing other stuff in my BPM. In my BPM I am catching mapping exception and then I have to send this to Soap Sender in SOAP fault message and in abstract interfaces we don't have option to give fault message types. Also, I am using S/A bridge and I have to close the brige in order to send some response to Soap Sender.
Is it possible to send soap fault when we close the S/A brige by send step.
Thanks,

How to throw exception in run() method of Runnable?
Hi, everyone:
I want to know how to throw exception in run() method of interface Runnable. Since there is no throwable exception declared in run() method of interface Runnable in Java API specification.
Thanks in advance,
GeorgeThanks, jfbriere.
I must add though that if your run() methodis
executed after a call to Thread.start(), then
it is not a good choice to throw anyRuntimeException
from the run() method.
The reason is that the thrown exception won't be
handled appropriately by a try-catch block.Why do you say that "the thrown exception won't be
handled appropriately by a try-catch block"? Can you
explain it in more detail?
regards,
George
Because the other thread runs concurrently with and independently of the parent thread, there's no way you can write a try/catch that will handle the new thread's exception: try {
myThread.start();
catch (TheExceptionYouWantToThrowFromRun exc) {
handle it
do the next thing This won't work because the parent thread just continues on after myThread.start(). Start() doesn't throw the exception--run() does. And our parent thread here has lost touch with the child thread--it just moves on to "do the next thing."
Now, you can do some exception handling with ThreadGroup and uncaughtException(), but make sure you understand why the above won't work, in case that was what you were planning to do. -
Weblogic throwing "null SOAP element Exception" in multi-part SOAP response
Hi All,
I'm using weblogic 10. My application is a webservice client generated using '*clientgen*', which is running on weblogic, and
is invoking a remotely hosted webservice ( Remotely hoseted webservice may not be running on weblogic).
I've the wsdl file of remotely hosted webservice.
Now the problem is with WSDL file (I suppose), have a look at this.
*<message name="m1">*
*<part name="body" element="tns:GetCompanyInfo"/>*
*</message>*
*<message name="m2">*
*<part name="body" element="tns:GetCompanyInfoResult"/>*
*<part name="docs" type="xsd:AnyComplexType"/> ------> assume all elements inside this complex type can be nil or minOccurs set to '0'*
*<part name="logo" type="xsd:AnyOtherComplexType"/> ------> assume all elements inside this complex type can be nil or minOccurs set to '0'*
*</message>*
<portType name="pt1">
<operation name="GetCompanyInfo">
<input message="m1"/>
*<output message="m2"/> -----> multi part message.*
</operation>
</portType>
Now here is sample message for the request(I've composed this message for this question):
<soap:Envelope> MESSAGE1
<soap:header/>
<soap:body>
<tns:m2>
<tns:GetCompanyInfoResult>
Blah Blah....
</tns:GetCompanyInfoResult>
<tns:docs>
Blah Blah....
</tns:docs> Assume no data for 'logo', so it's not returned. Since all its elements can be nillable.
<tns:m2>
</soap:body>
</soap:Envelope>
First of all, is this SOAP response is valid? I'm not sure about *'message' and 'parts' in SOAP*, but according to XML schema standards it's invalid.
Because, according to *'message' m2, 'logo' is missing*, eventhough all it's elements are nillable in such case there should be *<logo/>* at the end.
I mean valid message should be like below
<soap:Envelope> '*MESSAGE2*'
<soap:header/>
<soap:body>
<tns:m2>
<tns:GetCompanyInfoResult>
Blah Blah....
</tns:GetCompanyInfoResult>
<tns:docs>
Blah Blah....
</tns:docs>
*<tns:logo/> ------------------> here is the change compared to above message. empty element.*
<tns:m2>
</soap:body>
</soap:Envelope>
Now the concerns are :
(1) Which is a valid response? Message1 or Message2
(2) If message1 is valid then why is weblogic throwing an exception 'null SOAP element', I suppose this is due to missing 'logo' element.
(To confirm this I've used tcpmonitor and found message1 as response but weblogic is still throwing 'null SOAP Element' exception,
which confirms it needs 'logo' as well, I suppose <logo/> at least). Is there any workaround for this in weblogic for multi-part messages?
(3) If message1 is invalid according to SOAP standards then You've answered my question. ---> I need to talk to the webservice provider in this case.....
Thanks in advance...Message 1 is not Basic Profile 1.1 compliant. It is specified by BP1.1 in section 4.4.1(http://www.ws-i.org/Profiles/BasicProfile-1.1-2004-08-24.html#Bindings_and_Parts) that when a wsdl:part element is defined using the type attribute, the serialization of that part in a message is equivalent to an implicit (XML Schema) qualification of a minOccurs attribute with the value "1", a maxOccurs attribute with the value "1" and a nillable attribute with the value "false".

How to Throw/Catch Exceptions in BPM
Hi All,
I've seen a couple articles that talk about how to Throw/Catch an execption in a BPM. My question has two parts:
1) RFC Call: I was able to catch an Fault Message in an exception step when calling an RFC (Synchronous Interface). What I wanted to do is use the fault message (exception) and store it in a DB for later review.
2) IDOC: I'm sending an IDOC to R3 from a BPM. The send step is enclosed in a block w/ an exception. The send step is throwing an error (IDOC adpater system error), but the exception is never thrown. My question is: when the error occurrs at the adapter level does it still throw an exception in a BPM?
Thanks for any tip/advice/anything!
Fernando.Hi Fernando,
1) Define a send step in the exception branch.
2) If u send a IDoc from R/3 to XI and the IDoc adapter is running to an error of course there cant be an exception in ur business process. Usually the IDoc adapter sends back status back up via ALEAUD. In case of success IDoc should have then '03', if the adapter cannot send anything the IDoc should remain at '39'. U should send a ALEAUD in case of exception of BPM switching to status '40', in case of success to '41'.

How can my custom DCErrorHandler class throw/handle an exception?
I had written a custom DCErrorHandler extending the DCErrorhandlerImpl as similar as shown in SRDemo example.
Assume that i have a method authenticateUser() in AppmoduleService Class calling from Backing Bean.java where in i encountered ArrayOutOfBoundsException. So how can i catch this exception without using try catch block? if i use
try{
authenticateUser();
catch(Exception eX)
{} the exception is well-handled.Then what exactly my customErrorHandler class doing?
Do the above customErrorHandler class help in this case by replacing try-catch?From where my customErrorHandler's methods are invoked.
If i want to do it exlicitly from any method of my backing bean class can i do it?
LoginBackingBean.java
public String loginButton_Action()
ArrayList userDetailsList = null;
LoginService service = (LoginService)ADFUtils.getLoginServiceInterface();
if(service != null)
userDetailsList = service.checkUserLoginDetails(getUsername(), getPassword());
if(userDetailsList != null && userDetailsList.size()>0) {
JSFUtils.storeOnSession("key_loggedUserDetails",userDetailsList);
return "success";
else
JSFUtils.addFacesErrorMessage("You have entered an invalid User name and/or Password.");
return "wrongLogin";
else{
return "wrongLogin";
Now assume that i have customDCErrorHandler class and also assume that an exception will be thrown ..say ArrayOutOfBoundException.
if i keep the above code in try and catch block the user login screen is remained as it is by catching the exception.
if i remove the try and catch block user screen if filled up with so many debugging messages as shown : "500 Internal Server Error
javax.faces.FacesException: #{login.loginButton_Action}: javax.faces.el.EvaluationException: java.lang.IndexOutOfBoundsException: Index: 1, Size: 0 at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:98) at oracle.adf.view.faces.component.UIXCommand.broadcast(UIXCommand.java:211) at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:287) at javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:401) at com.sun.faces.lifecycle.InvokeApplicationPhase.execute(InvokeApplicationPhase.java:95) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:245) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:110) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:213)
So can we avoid this by using my customDCErrorHandler ???? If so i need a sample code.
More over if i use a customDCErrorHandler class,
Do i need to bother about the exceptions occuring in the application? -
How to Handle RFC delivery exception (rfcClientException) in XI?
I have a following scenario.
I have an outbound soap interface (sender) and inbound RFC(receiver). When the soap message is posted it goes to receiver where it has to execute the RFC. It tries to convert the XML to RFC and throws the following exception.
com.sap.aii.af.ra.ms.api.DeliveryException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not convert request from XML to RFC:com.sap.mw.jco.JCO$ConversionException: (122) JCO_ERROR_CONVERSION: Date 'xxxx-xx-xx' has a wrong format at field CREAT_DATE: Unparseable date: "xxxx-xx-xx
I defined the fault message and attached it to the Inbound Interface. I also defined the mapping of receiver exception message to fault message. I am expecting a fault message back to sender which is not happening.
When I go to moni and try to look for the error in the response message I see the following.
<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

How to expose a SOAP web service from HCP
Hello All,
Currently I am trying to create a SOAP web service within a HCP Java application to allow backend systems to consume data stored in HCP.
This is the planned scenario:
1. Create data in HCP - therefor I am using JPA and a oData Model.
2. Backend uses web service to consume data from HCP - with this point I do have some problems.. I do want to create a SOAP web service in order to achieve this.
Is there an easy way to create a SOAP web service in HCP? There are many tutorials in the internet of how to create a SOAP web service in 20 sec´s, but non of these helped me. I do was able to consume a SOAP web service in HCP coming from the ByD, but the other way around seems pretty complicated...
Can I make use of the Eclipse functions to create a web service? (New --> Other... --> Web Services --> Web Service and than choose the Button up Java bean Web Service type)
Have any of you some coding snippets that would probably help me out?
I have unsuccessfully tried to use the @WebService, @SOAPBinding, @WebMethod notation in my java classes...
Thank you,
SwenHello Nedelcho,
Yes. All the required jar files are in the lib directory.
Currently I am able to create a web service locally.
But when I deploy that to the cloud server my JPA service is not working any more.

How to resolve preverifying class exception while building

actually i need to run web application on mobiles (PDA), can any one suggests how to resolve the above exception and what are the jar files required in classpath.
Please let me know.

ST_Reddy.Then leave it as it is. If the method doesn't throw the exception it is not a problem.
If you need to throw the exception in some rare cases, then throw RuntimeException. It is not required to declare such exception in interface. -
WPUMFactory.getUserFactory() throws null pointer exception
Hi,
I am trying to use KM API's to read files from KM repository. I am using the below code as mentioned in the blog: How to download KM documents using Web Dynpro Java

cmadmin_service is a existing user that can be used to access KM resources .

How to handle multiple save exceptions (Bulk Collect)
Hi
How to handle Multiple Save exceptions? Is it possible to rollback to first deletion(of child table) took place in the procedure.
There are 3 tables
txn_header_interface(Grand Parent)
orders(parent)
order_items (Child)
One transaction can have one or multiple orders in it.
and one orders can have one or multiple order_items in it.
We need to delete the data from child table first then its parent and then from the grand parent table.if some error occurs anywhere I need to rollback to child record deletion. Since there is flag in child table which tells us when to delete data from database.
Is it possible to give name to Save exceptions?
e.g.
FORALL i IN ABC.FIRST..ABC.LAST SAVE EXCEPTIONS A
FORALL i IN abc.FIRST..ABC.LAST SAVE EXCEPTIONS B
if some error occurs then
ROLLBACK A; OR ROLLBACK B;

AnuIf you have one or two places in your code that need multiple exceptions, just do it with multiple catch statements. Unless you are trying to write the most compact Programming 101 homework program, inventing tricks to remove two lines of code is not good use of your time.
If you have multiple catches all over your code it could be a code smell. You may have too much stuff happening inside one try statement. It becomes hard to know what method call throws one of those exceptions, and you end up handling an exception from some else piece of code than what you intended. E.g. you mention NumberFormatException -- only process one user input inside that try/catch so it is easy to see what error message is given if that particular input is gunk. The next step of processing goes inside its own try/catch.
In my case, the ArrayIndexOutOfBoundsException and
NumberFormatException should be handled by the same way.Why?
I don't think I have ever seen an ArrayIndexOutOfBoundsException that didn't indicate a bug in the code. Instead of an AIOOBE perhaps there should be an if statement somewhere that prevents it, or the algorithm logic should prevent it automatically. -
How to use user defined exception class
Hi all
I just need som help with creating a user defined exception class.
Im writing a small/simple text editor.
My exception class looks like this:
public class myExcp extends Throwable
private String message;
public myExcep(String message)
this.message = message;
public void display()
System.out.println(message);
I would like to use it when a user tries to open a exe-file instead of a txt file.
Here is some code from the editor:
if (e.getSource() == open)
saveOld();
if (fc.showOpenDialog(null)== JFileChooser.APPROVE_OPTION)
readFile(fc.getSelectedFile().getAbsolutePath());
saveas.setEnabled(true);
So, should I use exception here or at the readFile method?
readfile:
private void readFile(String fileName)
try
String tmp = fileName.substring(fileName.length() -4, fileName.length());
if (!tmp.equals(".exe"))
FileReader r = new FileReader(fileName);
textarea.read(r, null);
r.close();
currentFile = fileName;
label.setText(currentFile);
changed = false;
catch (IOException e)
JOptionPane.showMessageDialog (this, "Cannot find the file " + fileName);
Where and how do I use my exception class.
Do I need to create an instance? Where?
Should the exception class extend Exception instead?
Thank you in advance /Extend Exception, not Throwable. It's a checked exception that way.
Follow the Sun coding standards and make that exception class name start with a capital letter.
When you extend Exception, override all four ctors.
What's that display method you added? Isn't getMessage() good enough?
You need to create a new instance just before you throw the exception, of course.
Sounds like a terrible design, by the way. Exceptions shouldn't be used like "go to" for app logic. They should signal unrecoverable conditions.
