java.lang.ClassNotFoundException Beim ersten Aufruf des Rest-Service

Question

Hallo ich für Jboss Rest-Anwendung zu entwickeln versuchen 6.3 mit Red Hat JBoss Developer Studio

Ich habe sehr seltsame Frage: Wenn ich meine Ruhe Dienst zugreifen erstes Mal über fiddller i erhalten folgende Ausnahme:

Der Server gibt den Statuscode 500 zurück. Beachten Sie, dass dies beim ersten Aufruf des Dienstes geschieht. Beim zweiten Anruf funktioniert der Rest-Service wie erwartet.

Meine Funktion sieht wie folgt aus

@POST 
@Path("matterNote") 
@Consumes("application/json") 
@Produces("application/json") 
public String matterNoteFunction(JSONObject json) throws IOException{ return "bla"; } 

ich wirklich bin verwirrt und und für alle Vorschläge warten.

EDIT:

Ich versuchte Download jackson-xc.jar hinzufügen, aber bekam followin Ausnahme (beim ersten Aufruf zu einem Dienst):

Danke.

Answer 1

Ich löste das Problem wie folgt: In meiner Anwendung ich json-lib.jar verwenden die anderen Abhängigkeiten muss in Classpath präsentiert wird richtig zu funktionieren. Ich entfernte alte Abhängigkeiten, dann hinzugefügt folgende:

Und das Problem ging weg.

Answer 2

I think XC Jackson lib is optional and The XC package allows you to use Xml Annotations (JAXB) in addition to the Jackson Annotations for mapping classes unless you need JAXB support just ignore the issue. 

Answer 3

Ich hatte ein gleiches Problem (mit Spring) mit:

<dependency> 
     <groupId>org.apache.cxf</groupId> 
     <artifactId>cxf-rt-rs-extension-providers</artifactId> 
     <version>3.0.2</version> 
    </dependency> 
    <dependency> 
     <groupId>org.codehaus.jackson</groupId> 
     <artifactId>jackson-jaxrs</artifactId> 
     <version>1.9.0</version> 
    </dependency> 

aber wenn ich Provider-Definition in der beans.xml von Mapper Definition erweitern:

<jaxrs:providers> 
     <bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"> 
      <property name="mapper" ref="jacksonMapper" /> 
     </bean> 
</jaxrs:providers> 
<bean id="jacksonMapper" class="org.codehaus.jackson.map.ObjectMapper" /> 

es begann ohne anfängliche Arbeit Ausnahme.
