Let's see if I understood you correctly ..
I can't speak for Ivy, but with Maven, you will sometimes have to install JARs manually to a repository, such as your local and possibly the one used when building your software.
Download the jar to your drive, and do something like this on command line:
mvn install:install-file -Dfile=ooweb.jar -DgroupId=ooweb -DartifactId=ooweb -Dversion=0.8.0 -Dpackaging=jar
Pick a more sophisticated groupId is you want, these are what you'll use in your pom when defining the dependency.
Was there some specific issue you ran into when setting up the JBoss repo? I did it a while ago by just adding this at the end of a pom:
<repositories>
<repository>
<id>jboss</id>
<url>http://repository.jboss.com/maven2</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
<repository>
<id>jboss-snapshot</id>
<url>http://snapshots.jboss.org/maven2</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
