Re: [jboss-dev] Scanning jars for package capabilities

"jar i" looks like it will also include the packages from the jars in the Class-Path attribute? From http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/jar.html#i : "Generate index information for the specified jarfile and its dependent jar files. For example: jar i foo.jar would generate an INDEX.LIST file in foo.jar which contains location information for each package in foo.jar and all the jar files specified in the Class-Path attribute of foo.jar. See the index example." On 18 Jun 2009, at 13:58, Jaikiran Pai wrote: > Resending with a zipped snapshot.
