Re: jzib.jar ---exception not threw while using CompressionFilter
thanks for your reply.
But I still don't get the exception and although logging has been enabled
already.
Some wonder...
Something was wrong ? My code was followings :
public class ClientProxy {
// log
private static final Logger log =
LoggerFactory.getLogger(ClientProxy.class);
// ssl support
private static final boolean sslSupport = Constants.isSSLEnable();
// compress support
private static final boolean compressSupport =
Constants.isCompressEnable();
private ClientMessage message;
public ClientProxy(ClientMessage message){
this.message = message;
}

Re: jzib.jar ---exception not threw while using CompressionFilter
Could you show us your log4j.properties or something similar?
Probably the exception message is being filtered by your logging
framework. Please check your settings.
