Below is the code Snippet.
FileInputStream fin = new FileInputStream(zipFile);
ZipInputStream zin = new ZipInputStream(fin);
ZipEntry entry = null;
String routerListUCM = "";
try {
entries:
while ((entry = zin.getNextEntry()) != null) {
if (entry.getName().startsWith("routes")) {
BufferedReader in = new BufferedReader(new InputStreamReader(zin, "UTF-8"));
if (true) {
//parse the xml of the route...
DOMParser dp = new DOMParser();
dp.parse(in);
Element e = (Element) dp.getDocument().getFirstChild();
String transferid = e.getElementsByTagName("transferId").item(0).getTextContent();
System.out.println("transferId=" + transferid);
int fileid = Integer.parseInt(transferid.split("-")[1]);
System.out.println("fileid=" + transferid);
String userList = e.getElementsByTagName("userList").item(0).getTextContent();
System.out.println("userList=" + userList);
String routeList = e.getElementsByTagName("routeList").item(0).getTextContent();
System.out.println("routeList=" + routeList);
routerListUCM = routeList;
if (routeList.toLowerCase().indexOf(myname().toLowerCase()) == -1) {
//my server is not in the current route...
//so skip this route table.
continue entries;
}
}
}
}
} catch (Exception e) {
System.err.println(e.getMessage());
e.printStackTrace();
}
in some cases after "continue entries;" and trying for next loop i see "stream close Exception" :/
error:Stream closed

It seems that your outermost BufferedReader object closes your nested streams (in particular ZipInputStream). Try to move your BufferedReader initalization code higher the looping logic.
Also this topic might be helpful: closing nested streams.
Update:
Ok, now everything is clear. Implementation code of DOMParser class shows clearly that parse method closes underlying InputStream source (just an excerpt of finally block):
} finally {
this.parser.reader.close();
}
What can be done in this situation is hacking your BufferedReader which is passed to DOMParser object. Here's an example:
public class HackedReader extends BufferedReader {
public HackedReader(InputStreamReader inputStreamReader) {
super(inputStreamReader);
}
@Override
public void close() {
// Close method doesn't do anything, that's the main sense of overriding.
}
// But you know exact method which will close your underlying stream.
public void hackedClose() throws IOException {
super.close();
}
}
