file - Alternative JAVA WAR/ZIP/JAR reader/manipulator library -

i struggling find alternative library make browsing some.war file.

problem need parse war file find specific jar name , of contents inside jar file. must parse contents e.g. pom.xml jars create separate maven project module dependencies , configuration appended other resources. found java.util.zip package bit inconvenient , cluttering.

is there alternative java.util.zip make parsing/reading war without such headaches switching between zipfile/zipentry -> jarfile/jarentry ? treat zip/war/jar , jar files inside war archive directory ? or 1 must craft his/her own solution ?

thank you,

i used zipinputstream similar task: if wrap 1 zipinputstream one, can transparently access archive inside archive without unpacking top-level one. here's short sample showing how use it:

public class ziptest {     public static void main(string[] args) throws ioexception {         try(inputstream = new fileinputstream(args[0]))         {             listzipentries(1, is);         }     }      private static void listzipentries(int indent, inputstream is) throws ioexception {         zipinputstream zip = new zipinputstream(is);         while(true) {             zipentry entry = zip.getnextentry();             if(entry == null)                 return;             system.out.printf("%"+indent+"s%s\n", "", entry.getname());             if(entry.getname().endswith(".zip") || entry.getname().endswith(".jar"))                 listzipentries(indent+3, zip);         }     } } 

it dumps names of files inside zip-archive. if encounters file name ends .zip or .jar, goes inside , dumps recursively. me looks quite simple , no third-party code necessary.
