hi,all:
i use a Client to invoke .net Web Services,but failed. The CXF
version is 2.6.2;jdk1.6.0_20
My code like this:
Client client = ClientProxy.getClient(port);
HTTPConduit httpConduit = (HTTPConduit) client.getConduit();
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setConnectionTimeout(5000);
httpClientPolicy.setAllowChunking(false);
httpClientPolicy.setReceiveTimeout(20000);
httpConduit.setClient(httpClientPolicy);
client.invoke("AddTestMethod ",xxxx,xxxx);
but *sometimes *the invoke throw an NullPointerException;the log is:
[2012-10-10 11:24:12 WARN
phase.PhaseInterceptorChain:org.apache.cxf.common.logging.LogUtils.doLog(LogUtils.java:405)]

I view the HTTPConduit source code
HTTPConduit.java 's close method is :
public void close() throws IOException {
try {
if (buffer != null && buffer.size() > 0) {
thresholdNotReached();
LoadingByteArrayOutputStream tmp = buffer;
buffer = null;
super.write(tmp.getRawBytes(), 0, tmp.size());
}
if (!written) {
handleHeadersTrustCaching();
}
if (!cachingForRetransmission) {
super.close();
} else if (cachedStream != null) {
super.flush();
cachedStream.getOut().close();
cachedStream.closeFlowthroughStream();
}
try {
handleResponse();
} finally {
if (cachingForRetransmission && cachedStream != null) {
cachedStream.close();
}
}
} catch (HttpRetryException e) {
handleHttpRetryException(e, connection);
} catch (IOException e) {
String url = connection.getURL().toString();
String origMessage = e.getMessage();
if (origMessage != null && origMessage.contains(url)) {
throw e;
}
throw mapException(e.getClass().getSimpleName()
+ " invoking " + connection.getURL() + ":
"
+ e.getMessage(), e,
IOException.class);
* } catch (RuntimeException e) {
throw mapException(e.getClass().getSimpleName()
+ " invoking " + connection.getURL() + ":
"
+ e.getMessage(), e,
RuntimeException.class);
}
