Is it possible to use a font not on the user's machine for text displayed in a java applet.
Like linking to a ttf font file in the same location as the java applet almost in an @fontface fashion.
I am making a distributed java app for which I need both parts of the app to run on one standard time. Since system times can be different I was thinking if java API contains some class to download time from a standard online source?
What is the best way to update a Java or GWT program from MySQL. For example, a MySQL database which holds Weather information... updating whenever the weather changes a degree. How would I update a Java / GWT field with each update. Would I use a thread to query every few seconds??
Hi,
I'm searching a possibility to paint a graph in Java using AWT. My knowledge of Java is still basic, so this is mainly for getting used to AWT, even if it's already "old".

I am in the process of converting some code from C# to Java. I have never used C# before, but it has been pretty easy up to this point.
I have a line that looks like this in the C# file:
coverage.createMethod = delegate (Gridpoint gp){
//Some method stuff in here, with a return objecct
}
What exactly is this trying to do? It seems a little bit like an inline class but I am not sure how to go about converting htis to java

I need a java graph library for visualization that I can incorporate in my own application. I found that jgraph is excellent for visualization but require explicit positioning of the nodes. Is there any open source java graph library that support automatic layout. Any suggestion will be really helpful for me.
Can any body please tell me what code is used for clear screen in java? For example in c++ "system("CLS"); " is used just like this what code is used in java for clear screen? Please help. Thanks!
Using the return keyword in Java code will return execution to the last piece of calling code in the call stack. If object foo calls baz.bar(), the return keyword in the bar method will continue code execution in foo.
Let's say I have object foo that calls foofoo that calls foofoofoo in the above scenario, and foofoofoo calls baz.bar(). Is there anyway in Java to use the return keyword, or something else, so that the code in the bar method can return all the way back up to foo?

Does anyone have a good solution for integrating some C# code into a java application?
The code is small, so I could re-write in java, but I would rather reuse the code if possible. Don't repeat yourself, etc.
Also, I know I can expose the C# as a web service or whatever, but it has some security/encryption stuff in there, so I would rather keep it tightly integrated if possible.
Edit: It's going to be on a server-based app, so "downloading" another runtime is irrelevant.
Currently, I have an Java Standalone Swing Application.
Now, when user clicks on the button in the Swing Application, I would like to launch another Java Application (Say : calculator.jar)
May I know what is the portable way to do so? So that it will work in multiple OS?
I'm trying to convert an old Delphi program I wrote into Java to compile and run on my Android phone. I'm running the Android 2.1 operating system but am using version 1.6 of the SDK.
I have a routine in Delphi where I set the colour of pixels on a canvas individually along the lines of:
image1.canvas.pixels[x, y] := GetMyTColor(x, y);
Is there a Java equivalent to the property on the Canvas:
property Pixels[X, Y: Integer]: TColor
Are Java annotations used for adding functionality to Java code besides just adding documentation about what's going on in the code? What's the most advanced/complex functionality you could add to your code through an annotation?
Is there any way to access the Windows Event Log from a java class. Has anyone written any APIs for this, and would there be any way to access the data from a remote machine?
The scenario is:
I run a process on a remote machine, from a controlling Java process.
This remote process logs stuff to the Event Log, which I want to be able to see in the controlling process.
Thanks in advance.
SEVERE: IOException while loading persisted sessions: java.io.WriteAbortedException: writi
ng aborted; java.io.NotSerializableException:
That means this object cannot be persisted on hard disk.
Does it imply that it's not safe to keep in Session objects that do not implement "Serializable"?
I haven't heard that there are limitations on saving non-serializable objects in Session object.
It simply means that Tomcat will always keep them in memory, right?

Switching from JVM 1.4 to 1.5 has performance benefits as per release notes.
http://java.sun.com/j2se/1.5.0/docs/relnotes/features.html#performance
We have Java 1.4 compiled classes which are run on 1.5 JVM, will these classes suffer in performance because they were compiled using 1.4 ?
I understand that the jvm is itself an application that turns the bytecode of the java executable into native machine code, but when using native threads I have some questions that I just cannot seem to answer.
Does every thread create their own
instance of the jvm to handle their
particular execution?
If not then does the jvm have to have some way to schedule which thread it will handle next, if so wouldn't this render the multi-threaded nature of java useless since only one thread can be ran at a time?
I want to a Java ME application that transfers any SMS received to a PC using bluetooth. The PC can then direct the Java ME application via bluetooth to send a response SMS. Is there library available for this architecture or I have to design it myself?
Is this approach correct or a better one exists? I want to use bluetooth as then I will not have dependency on the cable.
test.java:
import javax.media;
Which directories are javax.media searched from?
I suppose those in CLASSPATH specified by javac -cp will of course be searched.
But will it also search in the directory where test.java locates?
And are there any other possible places that will be searched?
The rich text editor must be implemented in Java, provide Swing support, and preferably be open source.
I'm looking to integrate it into an existing Java/Swing application.
Thanks.
A friend of mine came to me with this strange behavior which i can't explain, any insight view would be appreciated.
Im running VS 2005 (C# 2.0), the following code show the behavior
int rr = "test".IndexOf("");
Console.WriteLine(rr.ToString());
the above code, print "0" which clearly show it should have return -1
This also happen in Java where the following Class show the behavior:
public class Test{
public static void main(String[] args){
System.out.println("Result->"+("test".indexOf("")));
}
}
Im running Java 1.6.0_17
Hello,
I'm looking for a library that could perform "easy" pattern matching, a kind of pattern that can be exposed via GUI to users.
It should define a simple matching syntax like * matches any char and alike.
In other words, I want to do glob (globbing) like sun's implemented logic http://openjdk.java.net/projects/nio/javadoc/java/nio/file/PathMatcher.html but without relation to the file system.
Ideas?
