<p>The question is why? Why does javac think I am calling run(), and does not find run(int bar)?

In this case, you are "most" inside the anonymous inner class that subclasses runnable and there is no method which matches <code>run(int)</code>.

<p>I have 2 different webapps (package into different war files) which needs to share some data via a cache (ehcache). I want to test out this idea with you to see if it works.</p>

You can implement your caching service as a Web-Service (for example) and use it from war1 and war2.</p>

<p>Is there a good tool to compare <em>specifically</em> web.config files to find specifically which settings are different values and which file has settings that don't appear in both.</p>
<p>XML comparison should do the trick, or an XSLT might work. There must be a tool for web.config settings out there?</p>
