A problem with using enumeration-seq with java.util.jar.JarFile.
Hi, I want to read the contents of one of the files in a jar file. Here's the documentation - http://download.oracle.com/javase/6/docs/api/java/util/jar/JarFile.html Now, the doc. of entries method specifies it returns an EnumerationJarEntry, whereas - (map #(class %) (enumeration-seq (.entries some-jar-file))) shows all are - java.util.jar.JarFile$JarFileEntry For this reason, the getInputStream method which expects a ZipEntry (a JarEntry could be passed to ZipEntry as the former derives from the latter) doesn't work on the above type. Is this an issue with enumeration-seq, or the way I am using it or is the doc. for JarFile is not correct or something else? Please let me know.

Re: A problem with using enumeration-seq with java.util.jar.JarFile.
JarEntries are ZipEntries - there is no problem here.
user= (supers java.util.jar.JarFile$JarFileEntry)
#{java.util.zip.ZipEntry java.util.zip.ZipConstants java.lang.Object
java.util.jar.JarEntry java.lang.Cloneable}
user= (isa? java.util.jar.JarFile$JarFileEntry
java.util.jar.JarEntry)
true

Oops. Sorry, my bad. I am not using the JarFile object for the call. -- You received this message because you are subscribed to the Google Groups Clojure group.

I've been hacking around with jars in clojure recently.
