Problem with Application getInitParameter()

[Tauren Mills]

Maybe I'm going nuts, but I can't figure out what is wrong.  It seems so
simple, but it isn't working.  I call getInitParameter in my application
twice.  One time it returns a value, the other it gets a null.  And the
correct xml is there in web.xml.

First, here is the pertinent application code (I've trimmed out unimportant
stuff):

public class DynamicApplication extends WicketeerBaseApplication {

    private MerchantInfo merchantInfo;
    private String siteBaseUrl;

    public MerchantInfo getMerchantInfo() {
        return merchantInfo;
    }
    public void setMerchantInfo(MerchantInfo merchantInfo) {
        this.merchantInfo = merchantInfo;
    }
    public String getSiteBaseUrl() {
        return siteBaseUrl;
    }
    public void setSiteBaseUrl(String siteBaseUrl) {
        this.siteBaseUrl = siteBaseUrl;
    }

    @Override
    protected void init() {
        super.init();
        this.siteBaseUrl = getInitParameter("site-base-url");
        this.merchantInfo =
GoogleOrderService.loadMerchantInfo(getServletContext(),getInitParameter("checkout-config-file"));
    }
}

Now here are the pertinent parts from web.xml:

    <!-- Base URL of the website.  Used in linkbacks from google checkout.
-->
    <context-param>
        <param-name>site-base-url</param-name>
        <param-value>http://localhost:8080/</param-value>
    </context-param>

    <!-- location of configuration file for google checkout with respect to
context
         root. Using the default path here. -->
    <context-param>
        <param-name>checkout-config-file</param-name>
        <param-value>/WEB-INF/checkout-config.xml</param-value>
    </context-param>

So, when the application init() runs, merchantInfo gets properly populated
with the correct MerchantInfo instance based on the contents of
checkout-config.xml.  So the init param name and value were read correctly.

But, then when I try to just get a simple string value for site-base-url, I
get back a null.  I've looked for typos, tried retyping the web.xml section,
swapping the order of getInitParam in init(), restarting... all sorts of
stuff.  It just always gets null.

Any possible thoughts on what might cause this?  Using wicket-1.3.3.
Pulling my hair out.  Maybe its just late and I need to sleep.

Is there a better way to get the server name so I don't even need to hard
code it?  urlFor() only gives back the path, not the server.

Thanks,
