Hi there.
I'm using the dosgi-cxf(rs) on eclipse 3.6.1.
I have register a exception/responseException Mapper, but i cannot get my
exception.
I got only Invocation Exception resource throws my custom exception ,but it
works when i fix cxf source
code(org.apache.cxf.dosgi.dsw.handlers.ServiceInvocationHandler)
ServiceInvocationHandler.java
public class ServiceInvocationHandler implements InvocationHandler {
private final static String REMOTE_EXCEPTION_TYPE = "REMOTE";
private static final Collection OBJECT_METHODS =
Arrays.asList(Object.class.getMethods());
private Map>> exceptionsMap
= new HashMap>>();
private Object serviceObject;
public ServiceInvocationHandler(Object serviceObject, Class<?> iType) {
this.serviceObject = serviceObject;
introspectType(iType);
}
public Object invoke(Object proxy, final Method m, Object[] params)
throws Throwable {
if (OBJECT_METHODS.contains(m)) {
if (m.getName().equals("equals")) {
params = new Object[]
{Proxy.getInvocationHandler(params[0])};
}
return m.invoke(this, params);
}
ClassLoader oldCl = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
final Object[] paramsFinal = params;
return AccessController.doPrivileged(new
PrivilegedExceptionAction() {
public Object run() throws Exception {
return m.invoke(serviceObject, paramsFinal);
}
});
} catch (Throwable ex) {
Throwable theCause = ex.getCause() == null ? ex : ex.getCause();
List> excTypes = exceptionsMap.get(m);
if (excTypes != null) {
throw ex.getCause().getCause();
// for (Class<?> type : excTypes) {
// if (type.isAssignableFrom(theCause.getClass())) {
// throw theCause;
// }
// }
}
throw new InvocationTargetException(
new ServiceException(REMOTE_EXCEPTION_TYPE, theCause));
} finally {
Thread.currentThread().setContextClassLoader(oldCl);
}
}
private void introspectType(Class<?> iType) {
for (Method m : iType.getDeclaredMethods()) {
for (Class<?> excType : m.getExceptionTypes()) {
if (Exception.class.isAssignableFrom(excType)) {
List> types = exceptionsMap.get(m);
if (types == null) {
types = new ArrayList>();
exceptionsMap.put(m, types);
}
types.add(excType);
}
}
}
}
}
Here my stuff.
Exception
public class ResourceException extends WebApplicationException {
/**
* @see java.lang.Throwable#getMessage()
*/
@Override
public String getMessage() {
return message;
}
String message;
/**
* @param arg0
*/
public ResourceException(Response arg0) {
super(arg0);
int read = 1;
byte buffer[] = new byte[2048];
InputStream in = (InputStream) this.getResponse().getEntity();
StringBuffer stringBuffer = new StringBuffer();
while (read > 0) {
try {
read = in.read(buffer);
stringBuffer.append(buffer);
} catch (IOException e) {
}
System.out.print(new String(buffer));
}
message = stringBuffer.toString();
}
public ResourceException(int status,String message) {
super(Response.status(status).entity(message).type("application/xml").build());
}
}
Exception Mapper
public class CustomExceptionMapper implements ExceptionMapper {
/**
* @see javax.ws.rs.ext.ExceptionMapper#toResponse(java.lang.Throwable)
*/
public Response toResponse(ResourceException arg0) {
Response response =
Response.status(arg0.getResponse().getStatus())
.type(MediaType.TEXT_PLAIN).entity(arg0.getResponse().getEntity()).build();
return response;
}
}
Response Exception Mapper
public class CustomResponseExceptionMapper implements
ResponseExceptionMapper {
public ResourceException fromResponse(Response r) {
return new ResourceException(r);
}
}
