Re: Why web.xml in my application runs twice when use Apache as WebServer?

Dood idea! Dodd.

I tried as you mentioned, but still starts the pool twice. The servlet to start the pool in the Init() method. I had a static boolean variable to check if the pool is already exists and another static counter to check how many times my Init() method get called. It looks like that the servelet get called twice, so the Init() method get called once in each servlet call. The static boolean varaiable are in the same status and the static count has the same number in two servlet calls. I really don't understand why? Will you please tell me in more detail how you solve this problem in your environment? Your great help is highly appreciated.

Thanks!

It may be calling the Init method twice. Don't know why this might be
happening, but you may try to set a static boolean condition around the
creation of the ConnectionPool and set it to false inside. That way if it
gets called twice it won't re-run. I've had to do this inside Init()
methods in WebSphere.

Subject: Why web.xml in my application runs twice when use Apache as Web
Server?

Hi,

I have a servlet to start the ConnectionPool, which I wrote and
registered it in web.xml of my application. I set the <load-on-startup>.
So, the ConnectionPool should be started when Tomcat starts.

My question is when Tomcat used as stand-alone, the ConnectionPool
started once. But when Apache was used as Web Server, the ConnectionPool
starts twice: once at the time to start Tomcat, the other one at the
time to start Apache. Therefore, the number of Connections doubled. I
doubt may be two web servers were used: Tomcat mini Web server and
Apache Web server. So, I comment out the port 8080 connector in
server.xml. But ConnectionPool still started twice. It looks like that
web.xml run twice. Is any one can tell me when use Apache as Web Server
how can run web.xml only once?

Any help to this question shall be highly appreciated.
