Hi Gabo
It apperas that the root cause of it is that a subresource method is invoked
and it returns null.
Now, JAXRSInvoker does check for 'null' but I can see now that the check is faulty, as the null is wrapped in a CXF specific wrapper
initially....I'll update the code now....Can you confirm please that your subresource method return null ?
Cheers, SErgey
Hi Gabo
NPE is always a bug - so I need to investigate.
Can you please post the spring configuration which you use (in sample form but with the same relationships between beans, etc...)
?
And a sample MyService bean ?
By the way is there any chance that spring 2.0.6 is still hanging around somewhere on the IPlanet's classpath, perhaps on the
system one ?
As additional info:
"/some/path/MyService/search" is meant to match an annotated method as follows:
@GET
@Path("/search/")
public MyObjects getMyObjects(
@HeaderParam("uri")
SearchObject so){
just missed the '/' after the keyword 'search'
"/some/path/MyService/search" has to match this method....Or do you mean
something else ?
Thanks, Sergey
Hi All,
On another occassion. The cause of the problem is obviously the path used. Not
sure why a NPE was thrown instead.

Hi All,
Just to add, the exception does not have a cause. fault.getCause() returns
null. :(

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.
