[jira] [Commented] (CXF-6070) NPE while calling a webservice using a clientproxy
[ https://issues.apache.org/jira/browse/CXF-6070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14188750#comment-14188750 ] Daniel Kulp commented on CXF-6070: -- 2.4 is fairly old so I'm not 100% sure, but it's possible that the 2.4 proxies didn't implement the finalize() stuff that would have shut down the resources when no longer in use. Or the finalize()/close() method didn't completely clean everything up. Or the ClientImpl or Service or something somehow held onto the proxy object preventing it from being garbage collected.

We are planning a upgrade cxf version in coming months ,we will use as your suggestion. It would be great if you provide your insights so as to why the same issue is not occurring when 2.4 version of cxf is used .

That all said, I'm adding:
{code:java}
if (bus == null) {
throw new IllegalStateException("Message received on a Client that
has been closed or destroyed.");
}
{code}
to the method to make the exception message a little clearer instead of an NPE.

[jira] [Commented] (CXF-6070) NPE while calling a webservice using a clientproxy
[ https://issues.apache.org/jira/browse/CXF-6070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14188710#comment-14188710 ] Daniel Kulp commented on CXF-6070: -- This is working kind of as designed. If you use a "*Service" object to create a proxy (service.getXYZ() calls), you are expected to use that proxy for making the calls to the service. Not dig into the proxy and use the client object directly for the calls. The access to the client is there to allow configuring of things prior to making the calls. The issue is that proxy that is generated is being garbage collected (since you aren't using it) which is causing it to cleanup and release a bunch of things including the HTTP conduits, the request/response contexts, etc... If you need just a Client object, use the JaxWsClientFactoryBean. That said, with 3.0.x, the proxy returned from the service.getXXX() calls implements the Client interface directly and thus could be used as above without the call to ClientProxy.getClient and using a direct cast instead. That would keep the proxy from being garbage collected. > NPE while calling a webservice using a clientproxy > -- > > Key: CXF-6070 > URL: https://issues.apache.org/jira/browse/CXF-6070 > Project: CXF > Issue Type: Test > Components: Simple Frontend >Affects Versions: 2.7.12, 3.0.1, 2.7.13, 2.6.16 >Reporter: Varun > > We have implemented a webservice client using apache-cxf . > When calling a webservice through a ClientProxy, for some reason there is an > exception > [main] INFO org.apache.cxf.service.factory.ReflectionServiceFactoryBean - > Creating Service > [main] WARN org.apache.cxf.phase.PhaseInterceptorChain - Interceptor for has > thrown exception, unwinding now > java.lang.NullPointerException: NullPointerException invoking > at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) > at > sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) > at > sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) > at java.lang.reflect.Constructor.newInstance(Constructor.java:526) > at > org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.mapException(HTTPConduit.java:1347) > at > org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.close(HTTPConduit.java:1336) > at > org.apache.cxf.transport.AbstractConduit.close(AbstractConduit.java:56) > at org.apache.cxf.transport.http.HTTPConduit.close(HTTPConduit.java:632) > at > org.apache.cxf.interceptor.MessageSenderInterceptor$MessageSenderEndingInterceptor.handleMessage(MessageSenderInterceptor.java:62) > at > org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:272) > at org.apache.cxf.endpoint.ClientImpl.doInvoke(ClientImpl.java:570) > at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:479) > at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:382) > at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:335) > at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:355) > at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:341) > Caused by: java.lang.NullPointerException > at org.apache.cxf.endpoint.ClientImpl.onMessage(ClientImpl.java:764) > at > org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.handleResponseInternal(HTTPConduit.java:1626) > at > org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.handleResponse(HTTPConduit.java:1515) > at > org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.close(HTTPConduit.java:1318) > ... 12 more > Exception in thread "main" java.lang.NullPointerException > at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:339) > > 1.Testing using a standalone java program. > 2.This doesn’t happen when apache cxf version 2.4 is used . > 3.When upgraded the version to 2.6 and above ,we are facing this issue. > Code used to invoke the webservice is : > TestService service=new TestService(); > Client client = ClientProxy.getClient(service.get*); > Map requestContext = client.getRequestContext(); > requestContext.put(org.apache.cxf.message.Message.MAINTAIN_SESSION, > Boolean.TRUE); > requestContext.put(ENDPOINT_ADDRESS_PROPERTY,faxUrl); > Object[] logOnResp= client.invoke(“webservice”,param1,param2,param3,param4); > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
