I am using Eclipse Mars, Apache Tomcat, Axis2, and Maven with its axis2-java2wsdl and axis2-aar plugins to create web service and its client.
The web service is simple at the moment: it has a list of Users (with User attributes: nickname and Id) and allows someone to create, search, get and delete a user.
Everything seems to run OK on the server side. I implemented the service and tested that it works OK with SOAP UI (the functions operate as they should).
Error:
However, when I run the Java code for the client, I get the following error:
Exception in thread "main" org.apache.axis2.AxisFault: org.apache.axis2.databinding.ADBException:
Unexpected subelement {http://user.ws.soar}nickName
The problems occurs when I return a custom User object to the client.
Here is the service.xml excerpt:
<operation name="getUser" mep="http://www.w3.org/ns/wsdl/in-out" namespace="http://user.ws.soar/xsd">
<actionMapping>http://user.ws.soar/xsd/getUser</actionMapping>
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</operation>
I found a similar post but this solution did not work for me.
Any ideas how to resolve this issue are appreciated.

I have a web application running on Wildfly 26 that uses SSE broadcasting and works correctly with http. However, when I switch to using an https endpoint, I get Wildfly log entries of:
WARN [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-1)
RESTEASY002186: Failed to set servlet request into asynchronous mode,
server sent events may not work
This happens with each registration attempt of the https endpoint but I never see this when registering with the http endpoint.
Testing with curl against the http endpoint results in curl waiting for events to show up (and keeps printing them out as it receives them) until I quit. Using curl to test the https endpoint, I will see the same headers I got from the http endpoint, namely:
HTTP/1.1 200 OK
Connection: keep-alive
Transfer-Encoding: chunked
Content-Type: text/event-stream
But after printing out my registration successful event, curl seems to believe the stream is closed and exits -- giving me my command prompt back.
My #GET MediaType.SERVER_SENT_EVENTS registration endpoint will create an OutboundSseEvent and send it to the SseEventSink to acknowledge successful registration to my SseBroadcaster instance (this is the event curl sees and prints before exiting). I then log a registration successful message before exiting the method. All of this appears to work correctly for both http and https but the stream doesn't stay open once the request endpoint completes because of the failure to run asynchronously as outlined above.
I have not found information on the causes and/or workaround solutions for my RESTEASY002186 problem. I posted a question on this issue last week using the Wildfly Google Group (https://groups.google.com/g/wildfly/c/SO2eHdvMEko) but thought I would try a wider audience since this doesn't seem to be a commonly experienced condition. I don't see any indications during initialization that WildFly will be unable to use asynchronous mode, it just complains when it tries and fails... Any help would be greatly appreciated!
Edit 6/6/2022
The code is running on an isolated network so I can't just cut/paste the code here, but I gutted the resources file to a bare minimum -- just leaving enough for the client to be able to register. The problem remains unchanged. The code is now essentially:
#Path("sse")
public class SseResources {
#GET
#Produces(MediaType.SERVER_SENT_EVENTS)
public void listen(#Context Sse sse, #Context SseEventSink sseEventSink) {
SseRegComplete regComplete = new SseRegComplete("sse-server");
OutboundSseEvent event = sse.newEventBuilder().
name(regComplete.getType().toString()).
id(regComplete.getEventId()).
mediaType(MediaType.APPLICATION_JSON_TYPE).
data(SseRegComplete.class, regComplete).
comment("Event Stream Registration Completed Successfully").
build();
sseEventSink.send(event);
}
}
Before the above simplified code, I had declared the resource as #ApplicationScoped, had Sse injected into it, and kept a reference to the SseBroadcaster so I could use it whenever an event would come in. I was catching the events to broadcast by using an #Observes method (which I also got rid of). I was calling register(sseEventSink) on the SseBroadcaster in the listen method so I could later call broadcast(outboundEvent) whenever I had updates to publish. I got rid of all that just to see if I could get the stream to stay open but to no avail. I still get the RESTEASY002186 message and curl still exits after printing out the regComplete event sent to it in the code above.
Edit 6/7/2022
Yesterday I was able to get my code working in a new vanilla Wildfly 26 install using an https endpoint URL by following these configuration instructions. Something I hadn't mentioned in the original post is that I am trying to add SSE functionality to an already existing app. It is several years old and we actually moved to Wildfly 26 about 6 months ago because of the log4j vulnerability in the earlier version of Wildfly we were using. I suspect that the problem is related to either our Wildfly configuration (perhaps because old settings were brought over that shouldn't have been) or some 3rd party dependency that is preventing Wildfly from using asynchronous mode.
We are using Shiro for authentication and authorization against an LDAP server -- perhaps Shiro has some hooks into the Wildfly runtime that are causing issues? After initial login, we use a session cookie in all subsequent calls. That is a difference from my test server but I don't think it is relevant because the call definitely passed authentication before executing the registration code. The only other thing that comes to mind right now is our web app ships with LogBack and tells Wildfly not to use the default logging framework.
I plan to start today by comparing the two standalone.xml files to see if anything jumps out at me as being fundamentally different. Is there anything else I should be checking for differences (I think there is a domain.xml file somewhere...)?
Edit 6/14/2022
This definitely has something to do with Shiro being in the loop. When I edit the web.xml file to have Shiro's filter-mapping url-pattern to not include the SSE endpoint, everything works as expected.
We are using WSO2 Carbon 4.2.0 through the WSO2 Application Server (AS) package. In replacing an older, highly customized Carbon installation (provided by a company that no longer supports the product, has abandoned it and refuses to work on it, and left us no details on how/what they modified in Carbon), we have deployed a couple web applications in the webapps container as they were deployed before in the older instance. We have changed our WebContextRoot in the carbon.xml from the default "/" to a sub-URL of ex: "/stuff", as is also detailed in the self-answered SO question here. However the answer given there is not detailed in what the OP actually encountered when he modified his WSO2 instance.
In testing the above configuration we noticed that if a user were to go to a non-existent web address on the server, depending on the format of the URL they are either:
redirected to a blank page;
receive a "500 Internal server error" (I suspect this is the embedded Tomcat?);
get sent to the Carbon login page (which we definitely do not want to happen for security reasons); or
get an XML document stating:
<faultString> The service cannot be found for the endpoint reference (EPR) /stuff/services/nonexistantservicename </faultString>
At least in the case of missing content we wish the user to be sent to a standardized 404 error page, or at the least be sent an HTTP 404 error by the server. For services the XML error is palatable, we can deal with that.
The only option for us right now to circumvent this issue is to place a proxy in front of the WSO2 instance, which would be another layer to manage and tune, and possibly degrade performance. Please know that I am not a programmer but just an admin with DevOps experience. I would not know how to handle this with e.g. a Java solution or re-coding parts of WSO2. Customizing the core product would also hamper future upgrades of WSO2, a scenario we are trying to dig ourselves out of now as detailed above. Is there no internal WSO2 mechanism to handle non-existent content? Can we not redirect any errors to a standard canned response page?
I'm using IBM Integration Bus v10 (previously called IBM Message Broker) to expose COBOL routines as SOAP Web Services.
COBOL routines are integrated into IIB through MQ queues.
We have imported some COBOL copybooks as DFDL schemas in IIB, and the mapping between SOAP messages and DFDL messages is working fine.
However, when the message reaches a node where a serialization of the message tree has to take place (for example, a FileOutput or a MQ request), it fails with the following error:
"The PIF data could not be found for the specified application"
This is the last part of the stack trace of the exception:

It seems like something is missing in my deployable BAR file. It's important to say that my application has the message flow and it depends on a shared library that has all the .xsd files (DFDLs).
I suppose that the schemas are OK, as I've generated them using the Toolkit wizard, and the message parsing works well. The problem is only with serialization.
Does anybody know what may be missing here?
OutputRoot.Properties.MessageType must contain the name of the message in the DFDL schema. Additionally when the DFDL schema is in a shared library, OutputRoot.Properties.MessageSet must contain the name of the library.
Sounds as if OutputRoot.Properties is not pointing at the shared library. I cannot remember which subfield does that job - it is either OutputRoot.Properties.MessageType or OutputRoot.Properties.MessageSet.
You can easily check - just check the contents of InputRoot.Properties after an input node that has used the same shared libary.
Faced a similar problem. In my case, a message flow with an HttpRequest node using a DFDL domain parser / format to parse an HTTP response from the remote system threw this error (PIF data could not be found for the specified application). "Re-selecting" the same parser domain & message type on the node followed by build / redeploy solved the problem. Seemed to be a project reference related issue within the IIB toolkit.
you need to create static libraries and refer to application.
in compute node ur coding is based on dfdl body

In a jhipster context (last version, 1.2.2), I get an error when I request the default application on an entity I have just generate using yo jhipster:entity generator.
I run a yo jhipster to create a vanilla application with mongodb as database, java 7 and nothing special.
Then I run grunt build and grunt server for hot reload on the client part and mvn spring-boot:run for the server side app.
When I go to the http://localhost:8080/ url, I get the normal page. I can sign in with either the user or admin login.
I run the yo jhipster:entity foo to get an exemple of rest service in the back end.
When I request for the foo resource with the URL http://localhost:8080/#/foo, I get the page to CRUD the resource as it is said on the jhipster website.
But when I try to create a foo item with the modal form, I get an error on the back end server log ([WARN] org.springframework.web.servlet.PageNotFound - Request method 'POST' not supported).
I can't figure out how to solve this.
Do I miss something in the documentation ?
Do you have any idea, hint ?
I have the same issue using H2 as development database instead of mongodb.
Thanks.

This might be due to MongoDB, if you have a date field.
We will release very soon a new and improved Entity sub-generator, which should work better for you. While testing it, I had a serialization issue with MongoDB and a date field, and I corrected it in this new version. This is due to Jackson which can't serialize Joda Time dates (the correct annotations were only generated for SQL databases, not NoSQL databases)
I am Using RESTful APIs in my application using Jersey 1.6.
Some database is also there.
I have created two .war files in my application. These are deployed on Glassfish server3.0.1 with no issues.(no errors/exceptions).
They make some REST calls to each other for transactions.(It has a proper xml format to send a transaction).
When I try to make a transaction it gives me exceptions like
A system exception occurred during an invocation on EJB AuthenticationRequestFilter method public com.sun.jersey.spi.container.ContainerRequest com.mypack1.mypack2.resources.filters.AuthenticationRequestFilter.filter(com.sun.jersey.spi.container.ContainerRequest)
javax.ejb.EJBException
at com.sun.ejb.containers.BaseContainer.processSystemException(BaseContainer.java:5119)
and at the end it says
[#|2011-04-26T12:06:32.356+0530|WARNING|glassfish3.0.1|org.apache.http.impl.client.DefaultHttpClient|_ThreadID=27;_ThreadName=Thread-1;|Authentication error: Unable to respond to any of these challenges: {}|#]
I am sure that the xml I send is correct according to database entries.(including authentication for the particular URL).
Is there anything like "container security". Whats may go wrong in this case.
Thanks in advance.
