Hi, Well, if you don't know the number of the parameters beforehand, you could use naming like param1, param2, param3.... etc. Then you could use loop like e.g. this: int i=1; String param = null; while((param = ap.getParameter("param"+i)) != null) { //...do something.... i++...

Hi, This is one way: Calendar cal = Calendar.getInstance(); cal.set(Calendar.DATE, Calendar.DATE-15); System.out.println(cal.getTime());

Hi, Try new SimpleDateFormat("hhmma"); If you look from java API documentation, the 'h' pattern is defined to be "hour in am/pm (1~12)" -Vepo

Hi, You can use Runtime.exec() to execute batch files just like any other executable files. I'm not sure what kind of bat file you are going to execute (what you except it to do), but this example below works fine. It runs a batch file that starts a java application named test. a simple batch...

Hi jamescpp, I thinks you code work ok itself, but when I tried to resolve this problem I found an very interesting thing: when you login like that the verbose mode is set to off. This is the reason why you can't see the whole server response. I had a command-file like this: username password...

Hi, To use ICMP you must have access to low-level network data (e.g. raw sockets in C). In java, Sockets are assumed be either TCP or UDP sockets and you don't have access to a packet level data. You could use implement ping with C and add it to your java application using JNI. Or you could use...

Hi, There is also a isDigit() method but it is only for characters. Alternative solution would be (but i'd prefer use that NumberFormatException catching): String s = "12"; if(isdigit(s)) { System.out.println(s + " is digit."); } else { System.out.println(s + &quot...

Hi Casey, Here is a _very_ simple example, but I think you get the idea from it. import javax.swing.*; import java.awt.event.*; public class MListener extends JFrame implements MouseListener { public static void main(String[] argv) { new MListener(); } public MListener() {...

Hi, Your class files should be in directory com\me\MyClass\, so jar-package must be created from the root. Lets assume that your sources are located in c:\classes\com\me\MyClass. You have to create a jar package from c:\classes\ jar cvf ownPackage.jar com\me\MyClass\*.class As you can see...

Hi, Maybe one of the easiest way is to use BASE64Encoder/Decoder (comes with Sun's SDK): import sun.misc.BASE64Encoder; import sun.misc.BASE64Decoder; public class B64Test { public static void main(String[] argv) throws Exception { // Encoding.... BASE64Encoder encoder = new...

Like this: String s = "ABCD"; String s1 = s.substring(0,s.indexOf("B")+1); String s2 = s.substring(s.indexOf("B")+1,s.length()); -Vepo

Hi, That's true that you need always declare a variable before you use it (i.e. define it's type). But after you have to declared the variable, you don't have to (you mustn't) declare it again. In this case you have declared the class member variables after you can use them in any method...

Hi, Have you initialized the myStuff object in constructor? If you have just declared the class variable, it means that myStuff is null.

Hi, Firstly I have to say that I not so familiar with runtime exec that I could explain that error, but try to execute that command using rt.exec("cmd /c " + ComUtility.getBlisProperty("RemoteBillSys")); -Vepo

Hi, You can get the textField's length like this: sometextfield.getText().length(); -Vepo
