The Java runtime has no java.net.URL.exists() method. You need to write
such method yourself or use the one contained in xxe.jar.
I've tested what follows and it seems to work fine:
---
<command name="urltest">
<macro>
<choice>
<sequence>
<test xmlns:url="java:java.net.URL"
xmlns:uu="java:com.xmlmind.xmledit.util.URLUtil"
expression="uu:exists(url:new('http://www.xmlmind.com/xmleditor/index.html'))"
/>
<command name="alert" parameter="Found"/>
</sequence>
<command name="alert" parameter="Doesn't exist"/>
</choice>
</macro>
</command>
<binding>
<keyPressed code="F2" />
<command name="urltest" />
</binding>
