XmlRpc Client won't die ...

[Marcin Skladaniec]

Hello !
I have a XmlRpcClient executing an rpc method on very unreliable server. I have to force quit XmlRpcClient.execute() from time to time, but I can't. I have even created a separate Thread for it, and I'm quitting the Thread after timeout. It is working but not always, when server receives xmlrpc request and freezes without any sign of life my thread is uninterruptible. Is my approach to this problem right or am I missing something ? Does anyone created some other workaround for missing timeout in XmlRpc framework ? 


This is the impoortant part of my code:


	public SpacialThread(String pRemoteDatabaseURL, String pXmlRpcMethod, Vector pXmlRpcParameters) {
super();


xmlRpcResponse = null;


xmlRpcMethod = pXmlRpcMethod;
xmlRpcParameters = pXmlRpcParameters;
// See setResponse
hasReceivedResponse = false;
hasBeenInterrupted = false;


try {
client = new XmlRpcClient(pRemoteDatabaseURL);
} catch (java.net.MalformedURLException e) {
logger.error("(hash: " + hashCode() + "): java.net.MalformedURLException thrown:\n" 
+ e);
}


start();
}


	public void run() {
try {
// This is a blocking call...
logger.debug("(hash: " + hashCode() + "): Attempting Xml Rpc transaction.");
// Set response explicitly (this should be thread safe?)
Object response = client.execute(xmlRpcMethod, xmlRpcParameters);
setResponse(response);


if (isInterrupted()) {
hasBeenInterrupted = true;
logger.error("(hash: " + hashCode() + "): Xml Rpc transaction interrupted explicitly. Exiting. (Communication with remote abandoned)");
} else {
logger.debug("(hash: " + hashCode() + "): Returned from Xml Rpc transaction.");
}


} catch (Exception e) {
// Something else gone wrong... log the error and leave the exception for reference.
logger.error("(hash: " + hashCode() + "): Xml Rpc transaction interrupted abormally. Exiting. (Communication with remote abandoned)");
setException(e);
} finally {
// Regardless of the situation, clean up and release the network resources (hopefully)
logger.debug("(hash: " + hashCode() + "): Xml Rpc transaction finilizing - releasing resources.");
client = null;
}
}
