Hi.
We are using CXF in our application but get some random errors under
heavy load.
The server holds a plugin-pool with the web-services.
The plugins are reused and in this scenario instantiated nearly at the
same time.
This is the main part of the plugin:(code have been removed for
viewability)
public class ValidateSipSynchPlugin implements SynchronousPlugin
{
private JAXBContext mContext = null;
private Marshaller mMarshaller = null;
@Override
public void execute(String id, InputStream in, OutputStream out)
throws IOException
{
ObjectFactory objFactory = new ObjectFactory();
ValidateSipResponse response =
objFactory.createValidateSipResponse();
response.setId(id);
response.setStatus(GetSipStatusType.ARCHIVED);
// set some other data...
marshaller = getMarshaller();
marshaller.marshal(objFactory.createValidateSipResponse(response), out);
}
private JAXBContext getContext() throws JAXBException
{
if (mContext == null)
{
mContext = JAXBContext.newInstance(ObjectFactory.class);
}
return mContext;
}
private Marshaller getMarshaller() throws JAXBException
{
if (mMarshaller == null)
{
mMarshaller = getContext().createMarshaller();
}
return mMarshaller;
}
}
I created a simple cli app that starts about 50 threads where all
threads make a request to the server.
The request is exactly the same but once in a while we get errors when
reading the response.
Below is the interceptor log from the client. notice the namespace
difference in the last to inbounded messages.
