I am writing a server-emu software for a not-so-popular mmorpg game, and I'm using mysql connector for c++ to connect with my database.

I have apache 2.2 and tomcat 5.5 running on a Windows XP machine. Which tomcat/apache connector is the easiest to set up and is well documented? mod_proxy_ajp would be the easiest to use if you are using Apache 2.2.

In your httpd.conf you need to make sure that mod_proxy and mod_proxy_ajp are loaded: LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_ajp_module modules/mod_proxy_ajp.so Then you can use the ProxyPass and ProxyPassReverse directives as follows: ProxyPass /portal ajp://localhost

I want to create a broker to broker connection between ActiveMQ and WebSphere MQ in an embedded broker. I know that exists the network connector in activemq to do that (broker-to-broker), but I don't know how to configure it to connect to WebSphere MQ. Doing a search in the web I found some different ways to do with XML configuration and I noticed that the XML tags used does not refer the network connector, but refers a <jmsBridgeConnectors> , so I do a research about this bridge connector by using java code but I wasn't able to find something that points me about how to do that. Is there an
