Connection details & timeouts in a java web service client
- by f1sh
Hello fellow Coders,
I have to implement a webservice client to a given WSDL file.
I used the SDK's 'wsimport' tool to create Java classes from the WSDL as well as a class that wrap's the webservice's only method (enhanceAddress(auth, param, address)) into a simple java method. So far, so good. The webservice is functional and returning results correcty. The code looks like this:
try {
EnhancedAddressList uniservResponse = getWebservicePort().enhanceAddress(m_auth, m_param, uniservAddress);
//Where the Port^ is the HTTP Soap 1.2 Endpoint
}catch (Throwable e) {
throw new AddressValidationException("Error during uniserv webservice request.", e);
}
The Problem now: I need to get Information about the connection and any error that might occur in order to populate various JMX values (such as COUNT_READ_TIMEOUT, COUNT_CONNECT_TIMEOUT, ...)
Unfortunately, the method does not officially throw any Exceptions, so in order to get details about a ConnectException, i need to use getCause() on the ClientTransportException that will be thrown.
Even worse: I tried to test the read timeout value, but there is none. I changed the service's location in the wsdl file to post the request to a php script that simply waits forever and does not return. Guess what: The web service client does not time out but waits forever as well (I killed the app after 30+ minutes of waiting). That is not an option for my application as i eventually run out of tcp connections if some of them get 'stuck'.
The enhanceAddress(auth, param, address) method is not implemented but annotated with javax.jws.* Annotations, meaning that i cannot see/change/inspect the code that is actually executed.
Do i have any option but to throw the whole wsimport/javax.jsw-stuff away and implement my own soap client?
