jar - Java Exclude Base Directory from Namespace -

i trying programmatically create runnable jar file. using following code:

the add method:

private static void add(file source, jaroutputstream target) throws ioexception     {       bufferedinputstream in = null;       try       {         if (source.isdirectory())         {           string name = source.getpath().replace("\\", file.separator);           if (!name.isempty())           {             if (!name.endswith(file.separator))               name += file.separator;             jarentry entry = new jarentry(name);             entry.settime(source.lastmodified());             target.putnextentry(entry);             //target.closeentry();           }           (file nestedfile: source.listfiles())             add(nestedfile, target);           return;         }          jarentry entry = new jarentry(source.getpath().replace("\\", "/"));         entry.settime(source.lastmodified());         target.putnextentry(entry);         in = new bufferedinputstream(new fileinputstream(source));          byte[] buffer = new byte[1024];         while (true)         {           int count = in.read(buffer);           if (count == -1)             break;           target.write(buffer, 0, count);         }         target.closeentry();       }             {         if (in != null)           in.close();       }     } 

its implementation:

try {             file[] files = new file("tmp").listfiles();             (file file : files) {                 system.out.println("archiving: "+file.getname());                 add(file, target);             }         } catch (ioexception e) {             e.printstacktrace();         }         try {             target.close();         } catch (ioexception e) {             e.printstacktrace();         } 

i trying add of contents of tmp directory jar, not want prefix of namespaces tmp.. tried using code iterate through the files in tmp , add them keep getting errors saying "no such file or directory". pretty sure that's because looking outside tmp directory. however, when change add(new file("tmp"+file.separator+file.getname()), target); end "tmp" in namespaces (because started tmp/ directory). there way around this?

here example:

i have jar file main-class attribute com.name.proj.projdriver when decompress tmp folder end file in tmp/com/name/proj/projdriver.class. recompress jar using manifest object old jar still specifying main class com.name.proj.projdriver tmp.com.name.proj.projdriver. how can avoid having tmp. prefix namespaces?

replace code this:

private static void add(file source, jaroutputstream target) throws ioexception     {       bufferedinputstream in = null;       try       {         if (source.isdirectory())         {           string name = source.getpath().replace("\\", file.separator);           if (!name.isempty())           {             if (!name.endswith(file.separator))               name += file.separator;             jarentry entry = new jarentry(name);             entry.settime(source.lastmodified());             target.putnextentry(entry);             //target.closeentry();           }           (file nestedfile: source.listfiles())             try{add(nestedfile, target);}catch(ioexception e){system.out.println(e);}           return;         }          jarentry entry = new jarentry(source.getpath().replace("tmp\\","").replace("\\", "/"));         entry.settime(source.lastmodified());         target.putnextentry(entry);         in = new bufferedinputstream(new fileinputstream(source));          byte[] buffer = new byte[1024];         while (true)         {           int count = in.read(buffer);           if (count == -1)             break;           target.write(buffer, 0, count);         }         target.closeentry();       }             {         if (in != null)           in.close();       }     } 

i have varied row:

jarentry entry = new jarentry(source.getpath().replace("tmp\\","").replace("\\", "/"));
