I'm a .NET developer learning Java EE. These two concepts seem to serve the same exact purposes in either system.
So which framework gets credit for inventing them?

Is there a simple way to have your "Service Layer" deployed separately from your web layer, so that I can reduce the number of times per week that I have to, package, build and deploy the entire WAR file?
I'm using Tomcat mostly, but I'm hoping for something more generic to Java web servers
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.

Is there a way in Java to find the "Last Fired Time" from a Cron Expression.
E.g. If now = 25-Apr-2010 10pm, cron expression "0 15 10 ? * *" (quartz) should return me 25-Apr-2010 10:15am
I do not care if we use standard cron expressions (like Unix and Quartz) or less popular ones if they can fetch me the correct "Last Fired Time"
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?
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?
I am facing a problem with my singleton when used across multiple class loaders. E.g Singleton accessed by multiple EJBs. Is there any way to create a singleton which has only one instance across all class loader?
I am looking for pure java solution either using custom class loader or some other way.
I see many similar questions, however I want to find the Username of the currently logged in user using Java.

But, I'm not quite sure.
Having played with Linq (to SQL and Objects) as well as the Entity Framework from Microsoft recently, I was wondering what the non-.Net (specifically Java) equivalents are?
I have a Java application complied to a collection of jars that I want to make installable on Ubuntu and SuSE. I Want the installer to be able to check for the JRE, register a file association and be able to load a website on un-install.
I understand Ubuntu and SuSE are based on different architectures, so is there a consistent way to do this?
Does anyone have an advice on utilities to use or guides to read to help me achieve what I'm trying to do.
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?

I'm trying to recompile a project I've been working on and I keep getting an error message when trying to load a property file:
The system cannot find the path specified.
I guess this has to do with the classpath. But I've added the path to the file in Properties- Java build path- Libraries (external class).
I also checked the .classpath file generated by eclipse, and the path is really there!
Why isn't Eclipse looking at the right path?
Hi.
I wanted a thing like I declare a variable: String a = "test";
