Odd, for me the inverse is true.  I need the most things on my classpath at
test time [servlet spec, junit], fewer at compile [servlet spec], and fewest
at run time [just my war].

Here's the snippet of my configurations, and their mapping.  I use
externalized configuration so there's added confs for configuration and
externalized WSDLs..

     <configurations
defaultconfmapping="runtime->runtime(*);config->config(*);test->runtime(*);compile->runtime(*)">

         <conf name="config"  description="LCFG configuration templates
associated with this module"/>
         <conf name="wsdl"  description="WSDLs associated with this module"/>

         <conf name="runtime" extends="config,wsdl" description="anything
necessary to run; bundled into EAR/WAR"/>
         <conf name="compile" extends="runtime" visibility="private"
description="anything necessary to compile"/>
         <conf name="test" extends="compile" visibility="private"
description="anything needed to run unit tests"/>
     </configurations>

Those configs still seem odd to me because for example when using Hibernate there are certainly fewer jars required to compile than run (logging for example).

I thought about this war problem a lot and came up with:
    defaultconfmapping="compile->compile(default);
                        runtime->runtime(default);
                        war->runtime(default)"

  <conf name="war"
        extends="runtime"
        />

Now I have removed all mention of a war configuration for everything that is not actually a webapp (I tried it the other way and it was a mess). Here is one of my new ivy.xml files:

<!DOCTYPE project>
<ivy-module version="2.0">
    <info organisation="com.geekster" module="tv"/>
     <configurations>
       <include file="${ivy.settings.dir}/buildenv.ivy.configurations.xml"/>
     </configurations>
     <publications>
        <artifact type="war" ext="war"/>
     </publications>

    <dependencies>
<dependency conf="compile" org="javax.servlet" name="servlet-api" rev="2.4"/> <dependency conf="compile" org="com.geekster" name="library.tvLib" rev="latest.integration"/> <dependency conf="compile" org="com.geekster" name="library.ajaxLib" rev="latest.integration"/> <dependency conf="compile" org="com.geekster" name="library.hibernate_utils" rev="latest.integration"/> <dependency conf="compile" org="org.hibernate" name="hibernate3" rev="3.2.2.ga"/> <dependency conf="compile" org="com.geekster" name="library.java_util" rev="latest.integration"/>

        <exclude conf="war" org="com.mysql" module="mysql-connector-java"/>
        <exclude conf="war" org="javax.activation" module="activation"/>
        <exclude conf="war" org="javax.mail" module="mail"/>
        <exclude conf="war" org="javax.servlet" module="jsp-api" />
        <exclude conf="war" org="javax.servlet" module="servlet-api" />

    </dependencies>
</ivy-module>

The new thing for me is to add the block of excludes which strip out all of the shared jars on my local Tomcat installations, but do so without needing to know which dependency (if at all) brought them into the mix - this was a new trick I just found out.

Now I REALLY wanted to be even a little more clever and put that block of excludes in a file in my ivy.settings.dir and include them into place, but it turns out the include directive isn't allowed there (nuts). That would have been an especially deluxe solution since I could have had different include files for different server setups in my environment (Tomcat, JBoss, whatever).

But at least I can standardize this block and rubber stamp it on my web project ivy.xml's without having to think about it.

If anyone has some more fantastic tweaks I'm all EARs...
