Then I would suggest find/writing a small Java ZipVerifier that will
do this verification for you.
I created a quick example of a verifier and it seems to do the job.
<!--- Start ZipVerifier.java --->
import java.util.zip.ZipFile;
import java.util.zip.ZipException;
import java.io.IOException;
public class ZipVerifier {
public static String EXCEPTION_STR = "";
public static boolean verifyZip(String filePath) {
try {
ZipFile zipFile = new ZipFile(filePath);
return true;
}
catch( ZipException ze ) {
EXCEPTION_STR = ze.getMessage();
}
catch( IOException ioe ) {
EXCEPTION_STR = ioe.getMessage();
}
catch( SecurityException se ) {
EXCEPTION_STR = se.getMessage();
}
return false;
}
public static void main(String[] args) {
if( args.length > 0 ) {
System.out.println( "Valid Zip file?: " +
ZipVerifier.verifyZip(args[0]) );
System.out.println( EXCEPTION_STR );
}
else {
System.out.println( "usage: java ZipVerifier <zipfile path>" );
}
}
}
<!--- End ZipVerifier.java --->
