public static void addEntry(File zip, String entry, InputStream content) {
	try {
		// read war.zip and write to
		ZipFile zipFile = new ZipFile(zip);
		ZipParameters parameters = new ZipParameters();
		parameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE);
		// this would be the name of the file for this entry in the zip file
		parameters.setFileNameInZip(entry);

		// we set this flag to true. If this flag is true, Zip4j identifies
		// that
		// the data will not be from a file but directly from a stream
		parameters.setSourceExternalStream(true);

		// Creates a new entry in the zip file and adds the content to the
		// zip
		// file
		zipFile.addStream(content, parameters);
