Hi All,
I encountered this during one of my test:
Service.java:
@GET
@Path("/search/")
@WebMethod
public MyObjects getMyObjects(
@HeaderParam("uri")
@WebParam(name="searchObject")
SearchObject so) {
}
SearchObject.java:
@XmlRootElement
@XmlType(name="SearchObject")
@XmlAccessorType(XmlAccessType.PROPERTY)
public class SearchObject {
public SearchObject(){
}
//important point here is that there is no other constructor other
than default.
}
I accessed the said method and encountered the following exception:

The above print out is generated as:
//this is registered as a provider.
RuntimeExceptionMapper.java:
private String generateMessage(RuntimeException fault, String subject){
String appDir = new File(".").getAbsolutePath();
//TODO: turn this to html for better viewing.
StringBuffer sb = new StringBuffer();
sb.append("\r\n");
sb.append("\r\nApplication location: ").append(appDir);
sb.append("\r\n");
sb.append("\r\nProblem encountered:
").append((fault.getMessage()==null ||
fault.getMessage().length()<1)?"No message":fault.getMessage());
sb.append("\r\n");
sb.append("\r\nStack trace: ");
for(StackTraceElement ste : fault.getStackTrace()){
sb.append("\t").append(ste.toString()).append("\r\n");
}
return sb.toString();
}
The JAXRSInInterceptor in the stacktrace led me to somewhere useful in
checking where it failed. I saw this log earlier up:
[25/Mar/2009:04:33:33] failure (24718): for host 222.127.215.98 trying
to GET /some/domain/MyObjects/search, service-j2ee reports: Parameter
Class some.domain.SearchObject has no constructor with single String
parameter, static valueOf(String) or fromString(String) methods
I am going to modify my code to include all the cause exceptions when
available. But would it be possible to echo the message up the stream? I
mean, it seems unnecessary to include all the causes when a message from
the root cause echoed at the latest exception could easily give an idea
of what caused the problem.
Thanks.
