How do I convert an applet to a standalone application.
Hi Everyone,
I am currently working on this Applet, I have tried putting the main in and building a frame to hold the applet but everytime I try something I just get new errors, What I conclusively want to do is put the applet in a frame and add menus to the frame. I have listed the code below, its quite a lot, I hope someone can help though, am pulling hair out.
Many Thanks. Chris

Two issues:
1) Applet has init(), start(), etc. Application has main().
2) Applet is a container and you can add stuff to it. With application, you need to create your own container.
What you want to do is code so that you can run either way. In the applet, create a Panel or JPanel and add everything to the panel. Then add the panel to the applet. Get that working as an applet.
Now add a main(). All it has to do is create a Frame or JFrame, add the panel to the frame and then call init().
On another subject, your code looks very good, except for the method length getting out of hand. Try breaking init() into pieces in a bunch of methods:
public void init() {
doThis();
doThat();
doTheOther();
private void doThis() {
// maybe a couple dozen lines here
// etc.

How to use JDBC Connection Pools in a standalone application?
Hi, there,
I have a question about how to use JDBC Connection Pools in an application. I know well about connection pool itself, but I am not quite sure how to keep the pool management object alive all the time to avoid being destroyed by garbage collection.
for example, at the website: http://www.developer.com/java/other/article.php/626291, there is a simple connection pool implementation. there are three classes:JDBCConnection, the application's gateway to the database; JDBCConnectionImpl, the real class/object to provide connection; and JDBCPool, the management class to manage connection pool composed by JDBCConnectionImpl. JDBCPool is designed by Singleton pattern to make sure only one instance. supposing there is only one client to use connection for many times, I guess it's ok because this client first needs instantiate JDBCPool and JDBCConnectionImpl and then will hold the reference to JDBCPool all the time. but how about many clients want to use this JDBCPool? supposing client1 finishes using JDBCPool and quits, then JDBCPool will be destroyed by garbage collection since there is no reference to it, also all the connections of JDBCConnectionImpl in this pool will be destroyed too. that means the next client needs recreate pool and connections! so my question is that if there is a way to keep pool management instance alive all the time to provide connection to any client at any time. I guess maybe I can set the pool management class as daemon thread to solve this problem, but I am not quite sure. besides, there is some other problems about daemon thread, for example, how to make sure there is only one daemon instance? how to quit it gracefully? because once the whole application quits, the daemon thread also quits by force. in that case, all the connections in the pool won't get chance to close.
I know there is another solution by JNDI if we develop servlet application. Tomcat provides an easy way to setup JNDI database pooling source that is available to JSP and Servlet. but how about a standalone application? I mean there is no JNDI service provider. it seems a good solution to combine Commons DBCP with JNID or Apache's Naming (http://jakarta.apache.org/commons/dbcp/index.html). but still, I don't know how to keep pool management instance alive all the time. once we create a JNDI enviroment or naming, if it will save in the memory automatically all the time? or we must implement it as a daemon thread?
any hint will be great apprieciated!
SamTo my knoledge the pool management instance stays alive as long as the pool is alive. What you have to figure out is how to keep a reference to it if you need to later access it.

How do I convert this Applet to launch from a JFrame instead??
A simple program where the user can sketch curves and shapes in a
variety of colors on a variety of background colors. The user selects
a drawing color form a pop-up menu at the top of the
applet. If the user clicks "Set Background", the background
color is set to the current drawing color and the drawing
area is filled with that color. If the user clicks "Clear",
the drawing area is just filled with the current background color.
The user selects the shape to draw from another pop-up menu at the
top of the applet. The user can draw free-hand curves, straight
lines, and one of six different types of shapes.
The user's drawing is saved in an off-screen image, which is
used to refresh the screen when repainting. The picture is
lost if the applet changes size, however.

How can I convert an int to a string?
Hi
How can I convert an int to a string?
/ad87geaoHere is some the code:
public class GUI
extends Applet {
public GUI() {
lastValue = 5;
String temp = Integer.toString(lastValue);
System.out.println(temp);
showText(temp);
private void showText(final String text) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
tArea2.setText(text + "\n");

How can I convert an InputStream to a FileInputStream ???
How can I convert an InputStream to a FileInputStream ???
Thanks for you reply, however, I am still stuck.
I am trying to convert my application (which runs smoothly) to a signed applet. The following is the original (application) code:
private void loadConfig() {
String fileName = "resources/groupconfig";
File name = new File(fileName);
if(name.isFile()) {
try {
ObjectInputStream in = new ObjectInputStream(new FileInputStream(fileName));
pAndGConfig = (PAGroupsConfig)in.readObject();
in.close();
return;
} catch(ClassNotFoundException e) {
System.err.println("++ERROR: "+e);
} catch(IOException e) {
System.err.println("++ERROR: "+e);
System.out.println("Can't find file: " + fileName);
Because all code and resources now reside in a Jar file (for the signed applet), I must use the following line to access the resources:
InputStream is = this.getClass().getResourceAsStream(fileName);
I then need to convert the 'InputStream' to 'ObjectInputStream' or 'FileInputStream' so that I can work with it.
I would be very grateful if you could help shed some light on the matter - Cobram -

Converting an Applet into an Application
I think I understand the basics of converting an Applet into an Application but Iam unsure on how you would go about passing the parameters that are normally stored in the HTML tag into the application.
Basically you'll need to provide your own getParameter
method. It's easy with a java.util.HashTable -- the
parameter name as the key.that means that i would have to go back and change the old code, correct? -
How can I sign My applet for IE and Netscape without JavaPlugIn?
I think we can sign our applets with Javasigner.exe but this certificate is not being
supported by IE and Netscape. If you want to use this certificate with IE and Nets.
you must install JavaPlugIn to all users. I dont want to choose this way.
I think we have one alternative for this purpose.
For Netscape: Signing Tool
For IE: The program that included SDK-Java
But I could not find SDK-Java any where.
I think Microsoft have gave up to support the Java certification...
I am not sure.
How can I prepare signed applet that can be run on IE and Netscape?
This applet will have some permissions.The tool you need for signing cab files for the MS JVM is signtool.exe. I beleive that the .NET version of this tool can be used, as the signing process was not Java specific. You do need certificates in a different format than for jarsigner or the netscape signing tool. Verisign will happily sell you two different certificates, but there is probably a way to convert between formats using openssl or similar.
You'll also need to package your files in a cab instead of a jar. cabarc.exe is what we use here. Again, it does not seem to be Java specific, so you can probably still find it despite Microsoft no longer making their Java tools available. -
I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?
The application Acrobat provides no language translation capability.
If you localize the language for OS, MS Office applications, Acrobat, etc to the desired language try again.
Alternative: transfer a copy of content into a web based translation service (Bing or Google provides a free service).
Transfer the output into a word processing program that is localized to the appropriate language.
Do cleanup.
Be well... -

i changed from i iphone 5 back to a iphone 4.. now my itunes does not recognise that i have a iphone 4! how do i convert my last back up (on iphone 5) to my new iphone 4?
In your case you can only restore from a backup that has been created with the same iOS version. An iPhone 4 can only run 7.1.2, and, unless your iPhone 5 did not run the same version, you can't use a newer iOS backup of the 5 on the iPhone 4
