isArchive uses: - JARStructure, + expects jars to be directories (isDirectory == true). + expects directories that are not also archives (unpacked jars) to have a META-INF to be recognized. - WebInfLibFilter, + accepts isArchive == true as a lib jar + file.isDirectory() == true && JarUtils.isArchive(file.getName()) as a lib jar. These are too lax and violate the servlet spec as only .jar archives are to be accepted to strictly conform to the spec (JBAS-2538). - AbstractDeploymentContext, + A non-archive, non-directory root is defaulted to the metadata location if one has not been set. other isDirectory uses: - WARStructure, + expects jars to be directories (isDirectory == true) and further filers on .war or WEB-INF existence. The general features we need are: - does a file have children - does a file have an input stream, and what is its encoding Marking a file as a directory via isDirectory could achieve the first. I would like to drop the isArchive attribute and add a contentType instead. A null contentType implies there is no meaningful input stream and one would expect null or an error if it was requested.
