OK so, let's say I have a Java applet that takes a while to load (~5 secs). It's getting the mysql-connector.jar and it's loading. Well.. instead of the gray box with the coffee logo... can I make it have a simple progress bar with the percent?
Thanks.
Why is it that in Java, a superclass' protected members are inaccessible by an indirect subclass in a different package? I know that a direct subclass in a different package can access the superclass' protected members. I thought any subclass can access its inherited protected members.
I need to invoke .jar file in separate JVM from another java application, and it very CPU-consuming, so it should run with background priority in order not to affect the rest of the system. Is there any cross-platform method to do this?
Hello,
I'm creating a java web application runing on a Tomcat server.
One of the functions fill in a StringBuffer variable with data.
At the end, I would like to propose the user to download the generated content packaged in a text file. This without having to store the file on the server.
I've been searching for a code snippet but couldn't find anything corresponding ...
I hope I've been clear enough on my problem.
Thanks in advance,

In C# you can easily read all classes from a given assembly.
I'm looking for equivalent feature in Java. I need this to automatically bind EJB beans to my Guice Module.
I need to use a few Cyrillic characters in a Java file and in order for Eclipse to allow me to do so I need to change the encoding for that file (currently to UTF-8).
Are there any possible problems that this could cause?
Is it possible to write objects in Java to a binary file? The objects I want to write would be 2 arrays of String objects. The reason I want to do this is to save persistent data. If there is some easier way to do this let me know.
Thanks in advance!
Given the following code:
public class Test {
public void method(Object o){
System.out.println("object");
}
public void method(String s) {
System.out.println("String");
}
public void method() {
System.out.println("blank");
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Test test=new Test();
test.method(null);
}
}
Java prints "String". Why is this the case?

Using JNI can we pass custom data types from Java to C (or vice versa)? I see a mapping of primitive datatypes to types in C however not too sure if we can send across our own data types (e.g. Send across or return an Employee object or something!).
2 Interfaces with same method names and signatures. But implmented by a single class then how the compiler will identify the which method is for which interface.In java.
This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth.
A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?
Hi crew,
I'm searching for a tool, which converts a jsp file into a java file without using a server like tomcat or something else.
Can anyone help me out?
I have seen that there are many books titled:

Learning just another language is not much work. However, getting familiar with all the supporting libraries is veeeery expensive and actually you cannot go too far without that.
Would you consider a worthy career investment to learn java once you already are an accepted professional of .NET or you would rather invest the same amount of energy to get deeper in the things you already know?
Hi there,
is it possible to start a new thread in a different process in Java?
I mean, I'm running a specific process and main thread, issuing ProcessBuilder for creating a new process. Before start() method is invoked, one must provide the command to be run in another process. Is it possible to start a new thread in newly created process?
Thank you in advance for the reply.
Best regards.
I see many similar questions, however I want to find the Username of the currently logged in user using Java.
Its probably something like:
System.getProperty(current.user);
But, I'm not quite sure.
If I wanted a single word that meant "conforming to Java language conventions", what would that be? Python has the term "pythonic". Would it be "javaish"?
I have a .net application which needs to expose a service consumed by a java client. The service can't be public. There should be some authentication mechanism for the client. What is the best way to do this? I'm new to web services and am confused by all the soap, wsdl etc. and have also heard a lot that it'll be a pain to get the two to communicate. Your thoughts?
