I try to build wsdl client for jre5 with JAX-WS RI 2.1.3 its my first expirience. I genereted classes with wsdl2java tool from cxf and wrote wrapper class around client looks like:
public class RequestHelper {
private DataLoadService service = new DataLoadService();
private DataLoadServiceSoap client;
private static String token;
//....my constructor....
public void sendData(data){
try{
if (tokenIsExpired()){
renewToken();
}
client.sendData(data, this.token);
}catch(SOAPFaultException e){
//...work with e
}
}
}
I can't understand how i can process exception in sendData method. I mean, for example, in HTTP we have status codes, we can read status code and decide which type of error we get from server and how we want process them.
In my case i have problem with token expired time. Sometimes sendData request goes to the server for a long time. And the token is no longer valid when the request is already on the server then i get exception with text message "Token expired". And i want catch this type of exception separately, somthing like this:
public class RequestHelper {
private DataLoadService service = new DataLoadService();
private DataLoadServiceSoap client;
private static String token;
//....my constructor....
public void sendData(data){
try{
if (tokenIsExpired()){
renewToken();
}
client.sendData(data, this.token);
}catch(SOAPFaultException e){
//...work with e
}catch(TokenExpiredException e){
renewToken();
client.sendData(data, this.token);
}
}
}
How i can achieve this with JAX-WS RI 2.1.3 library?
UPD:
} catch (SOAPFaultException e) {
SOAPFault f = e.getFault();
f.getFaultString() //yes here we have error description with "Token"
//but with locals dependency, this is not safe handle exception by this value
f.getFaultCode() //here simply string "soap:Receiver", do not know how i can recognize only "token exceptions"
}
Find out what is been returned as part of the SOAPFaultException from the server. If the Exception contains the error message then we can write something like below. note: Error code will be the best way to handle this.
try{
if (tokenIsExpired()){
renewToken();
}
client.sendData(data, this.token);
}catch(SOAPFaultException e){
if(e.getFault().getFaultString().equalsIgnoreCase("Token expired") ) {
renewToken();
client.sendData(data, this.token);
}
......
}
Another way is to have custom SOAP exception thrown from the sever with error code and error message and handle that in the code

I use an external rest api in my spring application, I can send json post requests to create objects but when a field is incorrect or if there is a duplicate it returns a 400 bad request error, and a body saying what the problem is.
I use Spring 5 with #PostExchange in the following code:
This is used to point spring into the right direction of the external api
public interface HardwareClient {
#PostExchange("/assetmgmt/assets/templateId/C04DBCC3-5FD3-45A2-BD34-8A84CE2EAC20")
String addMonitor(#RequestBody Monitor monitor);
}
This is the helper that is autowired into the class where I have the data that needs to be sent.
#Component
public class HardwareHelper {
private Logger logger = Logger.getLogger(getClass().getName());
#Autowired
HardwareClient hardwareClient;
#Async
public Future<String> addMonitor(MonitorForm monitorForm){
try {
Monitor monitor = new Monitor(monitorForm.objectID(), monitorForm.model(), monitorForm.make(),monitorForm.serialNumber(), monitorForm.orderNumber(),monitorForm.budgetholder(),monitorForm.ownership());
hardwareClient.addMonitor(monitor);
return new AsyncResult<String>("Success");
} catch (Exception e){
logger.info("HardwareHelper.addMonitor error: " + e.getMessage());
//todo error handling
}
return null;
}
}
When an error occurs the logger will print the error but I need to be able to control what happens after based on the response. So I need to see the body of the post request that is returned after. If everything goes well an ID is returned that I can read by printing the results of the addMonitor() method, but this is obviously not possible when it throws an exception as it skips to the catch part. How do I scan the request body when an error is thrown and handle this appropriately
public string prospect(List<ProspectRequest> prospectRequest, String primaryClientId) {
if(p2p(primaryClientId)=="Success") {
for(ProspectRequest prospect : prospectRequest) {
p2p(prospect.getId());
}
// rest of code i would like to continue
}
}
public string p2p(String id){
crmApi.getProspectId(id);//this is external client api
String message = "Success";
return message;
}
if p2p(primaryClientId) is failed then I need to stop the entire process .How do i like to continue with "rest of code i would like to continue".
if the feign client api crmApi.getProspectId is success then the success message is returned and then its a good case.
If the crmApi.getProspectId api gives error then I still need to continue the p2p() program for next set of clients also .How does that work.
Thanks in Advance.
Seems like you just need to use a try catch finally block
public string prospect(List<ProspectRequest> prospectRequest, String primaryClientId) {
try {
if(p2p(primaryClientId)=="Success") {
for(ProspectRequest prospect : prospectRequest) {
p2p(prospect.getId());
}
} catch (RuntimeException e) {} // Exception can be specified exp. RuntimeException
finally {
// rest of code i would like to continue
}
}
}
public string p2p(String id){
crmApi.getProspectId(id);//this is external client api
String message = "Success";
return message;
}
if you need something out of the first if-block you can put an option (if the if-block fails) in the catch-block. When
if(p2p(primaryClientId)=="Success") {
for(ProspectRequest prospect : prospectRequest) {
p2p(prospect.getId());
}
throws an checked exception you need to change RuntimeExpection to the superclass Exception
edited:
for(ProspectRequest prospect : prospectRequest) {
try {
p2p(prospect.getId());
} catch (RuntimeExpection e) {}
}
I am coding a server application that will receive DFT_P03 messages with an added ZPM segment (which i have created a class for as per the HAPI documentation). Currently i am able to access this field as a generic segment when doing the following :
#Override
public Message processMessage(Message t, Map map) throws ReceivingApplicationException, HL7Exception
{
String encodedMessage = new DefaultHapiContext().getPipeParser().encode(t);
logEntryService.logDebug(LogEntry.CONNECTIVITY, "Received message:\n" + encodedMessage + "\n\n");
try
{
InboundMessage inboundMessage = new InboundMessage();
inboundMessage.setMessageTime(new Date());
inboundMessage.setMessageType("Usage");
DFT_P03 usageMessage = (DFT_P03) t;
Segment ZPMSegment = (Segment)usageMessage.get("ZPM");
inboundMessage.setMessage(usageMessage.toString());
Facility facility = facilityService.findByCode(usageMessage.getMSH().getReceivingFacility().getNamespaceID().getValue());
inboundMessage.setTargetFacility(facility);
String controlID = usageMessage.getMSH().getMessageControlID().encode();
controlID = controlID.substring(controlID.indexOf("^") + 1, controlID.length());
inboundMessage.setControlId(controlID);
Message response;
try
{
inboundMessageService.save(inboundMessage);
response = t.generateACK();
logEntryService.logDebug(LogEntry.CONNECTIVITY, "Message ACKed");
}
catch (Exception ex)
{
response = t.generateACK(AcknowledgmentCode.AE, new HL7Exception(ex));
logEntryService.logDebug(LogEntry.CONNECTIVITY, "Message NACKed");
}
return response;
}
catch (IOException e)
{
logEntryService.logDebug(LogEntry.CONNECTIVITY, "Message rejected");
throw new HL7Exception(e);
}
}
I have created a DFT_P03_Custom class as following :
public class DFT_P03_Custom extends DFT_P03
{
public DFT_P03_Custom() throws HL7Exception
{
this(new DefaultModelClassFactory());
}
public DFT_P03_Custom(ModelClassFactory factory) throws HL7Exception
{
super(factory);
String[] segmentNames = getNames();
int indexOfPid = Arrays.asList(segmentNames).indexOf("FT1");
int index = indexOfPid + 1;
Class<ZPM> type = ZPM.class;
boolean required = true;
boolean repeating = false;
this.add(type, required, repeating, index);
}
public ZPM getZPM()
{
return getTyped("ZPM", ZPM.class);
}
}
When trying to typecast the message to a DFT_P03_Custom instance i get a ClassCastException. As per their documentation, i did create the CustomModelClassFactory class but using this i just get tons of validation errors on the controlId field.
I am already using an identical logic to send custom MFN_M01 messages with an added ZFX segment and that works flawlessly. I understand there is some automatic typecasting being done by HAPI when it receives a DFT_P03 message and that is likely what i need to somehow override for it to be able to give me a DFT_P03_Custom instance instead.
If you have some insight on how i can achieve this without having to use a generic segment instance please help!
Thank you!
I finally figured this out. The only way i got this to work was to generate a conformance profile XML file (using an example message from our application as a base) with the messaging workbench on the HAPI site and use the maven plugin to generate the message and segment classes. Only with these classes am i able to correctly parse a message to my custom class. One thing to note is that it DOES NOT work if i try to use the MSH, PID, PV1 or FT1 classes provided by HAPI and use my Z-segment class. It only works if all the segments are the classes generated by the conformance plugin. This combined with a CustomModelClassFactory class (as shown on the HAPI website) and the proper package structure finally allowed me to access my Z-segment.
I am building an application that will send messages using STOMP over websockets. I want to send messages without a request being made by the client. According to the documentation, I can do this by using convertAndSend.
However when I try and do this, I get a null pointer exception. Please see code below:
public class ParseJSON {
#Autowired
private SimpMessagingTemplate template;
public void getDetails(String json) {
try {
Tweet status = sendDetails(TwitterObjectFactory.createStatus(json));
sentToWebApp(status);
} catch (TwitterException e) {
e.printStackTrace();
}
}
#Scheduled(fixedDelay = 50)
private void sentToWebApp(Tweet status) {
System.out.println(status);
this.template.convertAndSend("/tweet/update", status);
}
}
Stack Trace:
java.lang.NullPointerException: null
at org.myproject.worker.ParseJSON.sentToWebApp(ParseJSON.java:62)
at org.myproject.worker.ParseJSON.getDetails(ParseJSON.java:51)
at org.myproject.worker.TwitterClient.run(TwitterClient.java:50)
at org.myproject.Controllers.TweetController.greeting(TweetController.java:37)
Can anybody pour any light onto my situation so I'm able to send a message via websocket without encountering an exception.
Thanks in advance.
Your template variable is not properly autowired thats why its giving nullpointerException .
you can check spring configuration to autowire correctly
I have web client (HTML5) and backend server based on RESTEasy webservices and session beans. In my server side code I am iterating over list of objects and per object i am executing some business logic:
List<TestTO> failedTestList = new ArrayList<TestTO>();
for (TestTO testTO : testTOList) {
try {
// some weired business logic :P
} catch (Exception e) {
logger.error("Unable to create data -" + e.getMessage());
failedTestList.add(testTO);
}
}
if (!failedTestList.isEmpty()) {
// throw custom exception embedded with failed TO list
}
I have written custome exception handlers, to catch exceptions and return proper response back to client. This class looks like:
public class CustomExceptionHandler implements ExceptionMapper<CustomException> {
public CustomException getCustomErrorCode(final CustomException customException) {
// Some logic to get cause and set error code
return customException;
}
#Override
public Response toResponse(final CustomException customException) {
return Response.serverError().entity(
"{\"Error Code\":\"" + getCustomErrorCode(customException).getErrorCode() + "\", "
+ "\"Error Message\":\"" + customException.getLocalizedMessage() + "\"}").build();
}
}
I am thinking of an option to send this failed TO list back to client, so that it can understand processing of which objects got failed. I was going through different articles, but could not find anything which fits my requirement.
Please give me an idea and link to reference, on how to implement such requirement. Please note that, my client expects response in JSON format. Please let me know, if you require more information.
Thanks.
