Yes, you are right. It throws an Stack Overflow exception, but... WILL EVER SOMEONE NEED AN ARRAY THAT LONG?. Maybe the developer make their languages to some "reasonable" limits.

Compile and Runtime Exceptions
Hi all,
What are Compile-time Exceptions and Runtime Exceptions.
and by the way,
What are Checked Exceptions and Unchecked Exceptions
Thanks in advancehttp://java.sun.com/docs/books/tutorial/essential/exceptions/index.html
There isn't really such a thing as a "compile time excepitons." "Exceptions" are when something goes wrong at runtime. You can, of course, get compilation errors because your code doesn't follow Java's syntactical rules, but we don't call those exceptions.
And of course, if your compiler is written in Java, then compile time for you is runtime for the compiler. (The compiler is a Java program that's running.) So it could throw an exception. But that's not your code. -
JSPC Compiler gives FileNotFound Exception from command line
I have problem running jspc from command line
From the browser, the jsp pages compile fine.
I have tested this on NT 4.0 and on HP UX 10.0 with Weblogic Server
4.5.1 and SP 9.
The command I typed in as follows:
$java weblogic.jspc -d /opt/b2berp/jspclassfiles/ - docroot
/opt/b2berp/web -keepgenerated true -classpath
/opt/jdk/1.2.2/lib/classes.zip:/opt/weblogic/weblogicaux.jar:/opt/b2berp/lib
I get the following exception:
I checked the file is in PATH and I am also specifying the absolute path
and filename.
My document directory is /opt/b2berp/web/auctions/
All of my jsp pages are under /opt/b2berp/web
This is also my web folder.
Gives error unable to find file

Does anyone know what is going on.

Runtime exception with ADG when compiled with ANT
Hi,
We are using Advanced Data Grid in our project and it compiles and produces a correct SWF file when compiled using the licensed FlexBuilder. This work fine for the development environment, but for the testing and staging environments we use ANT to automate the build process of both Flex and Java components.
When the swf is built using ANT, we get a runtime exception when the page containing the ADG is accessed in web browser. The exception is
TypeError: Error #1007: Instantiation attempted on a non-constructor.

Thanks in advance.On forums of slackware there was a reference towards the program "free" which is being executed from /usr/bin/free whereas the program on slcakware resides in /bin/free or vice versa. Creating a ymlink should solve the problem. Dunnow (yet) if that works

Is there any path I need to add in CLASSPATH other than what I have?
Also, check few oracle docs regarding the same. But, nothing can eliminate this problem.
Can you please suggest?

Handling Java runtime exception on Vista OS
Hello Forum members,
This is regarding the handling of runtime exception on Vista machine with JRE 1.4.2_14.
Iam working on client / server scenario where i need handle the run time exception say SocketExcpetion or IOException like "No Route to Host " exception whenever there is network connection problem with the server.
Problem:
On Windows 2000 and Windows XP OS , Iam able to get the Socket Exception from the server when there is network connection problem and based on this Iam displaying some error message to the user but on Vista am not able to catch these runtime exception since Vista OS is blocking the runtime excpetion thrown from the server or network.
Please let me know how to configure the Vista OS to allow the runtime exception to be thrown to the user or how to handle the programmatically (using java ) on Vista OS to throw exception.
Any suggestion is welcome
Best regards,
SudhirI have heard that on Vista machine , by default the windows firewall will block all the runtime exceptions (especially the ones which are thrown from the server).
This problem is with respect to Client/server scenario where the server will throw SocketException when there is network connection problem and on the client side i need to catch and handle this exception to display appropriate message to the end user.
Background: Iam able to handle exception thrown from the server on Windows 2000 and Windows XP but on Vista am facing the above said problem i.e. am not able to get any exception from the server. -
Runtime exception java.lang.ClassNotFoundException on executing Stored Proc

Runtime exception for other than programming error.
In a conversation the question arose whether it could be a case of throwing a runtime exception for anything other than a bug. The tutorial on oracle site says "These Usually Indicate programming bugs" leading to think that can be used in situations in which there is no bug.
Anyone have a practical example of a runtime exception when there is no bug?
Thanks.937643 wrote:
Ok. But. Do you think that in these cases the use of a runtime exception could be considered a bad practice?That's actually a matter of some debate.
On the one hand, Java has defined two major kinds of exceptions since the very beginning (unchecked exceptions, which are RuntimeException, Error, and their descendants; and checked exceptions which are everything else). The intended use of those was that checked exceptions should be for things that can normally go wrong in the execution of a program, even without a bug or without a major internal JVM error, such as a failed attempt to persist something or a network connection dropping--stuff that a programmer might normally be expected to deal with; while unchecked exceptions were created for things that a programmer would not normally handle in his code (except possibly at major architectural boundaries), like buggy code or an internal JVM failure.
With the rule about having to catch or declare checked exceptions, but not unchecked ones, that makes it easy for programmers so say, "Okay, I know exactly what can go wrong here that I might be expected to handle and I can therefore choose what to do with it; there will be no surprises. But I don't have to deal with problems that are outside my normal responsibility, like somebody passing me a null when they shouldn't have." It gives a programmer a nice bit of control, and the ability to know he hasn't missed something, kind of like the type safety provided by a strongly typed language.
At least that's the theory.
In practice, most checked exceptions either just get bubbled up to the next layer (via a throws clause), or caught wrapped in a fairly generic layer-appropriate exception and rethrown. There's not a whole lot of use made of what checked exceptions provide, and there's a lot of ugly boilerplate code that doesn't do anything useful for the app but is just there to satisfy the compiler.
So, some people think that checked exceptions are useless, or mostly useless, and favor unchecked exceptions in most or all cases. I believe that's part of the philosophy of Spring, but I'm not totally sure.
The idea is that since most of the time you can't do anything about exceptions that might be thrown to you, it's wasteful and pointless to have all that code to catch and rethrow. In this viewpoint, it would be better if, for example, not providing a throws clause at all meant that you could throw any exception. Any given code can still catch specific exceptions that it knows it can handle, but we don't have to write a bunch of code notating something that we're not really doing anything about.
Personally, I used to be totally in the checked exception camp. However, all the pointless boilerplate is wearing me down. I'm still not completely convinced though, and here's why: If I'm calling a method, I'd like to at least be able to see what might go wrong, so that I can decide how to deal with it. If all exceptions were unchecked, and the throws clause were optional, a conscientious developer could still provide it, and list the unchecked exceptions his method might throw to me, and/or he could document them in the javadoc comments. But a lot of developers won't do that, or even if they start to, as their method evolves, without the compiler to enforce it, they won't keep it up to date.
So there are advantages to both approaches. I personally would to know that the information will always be available to me, but for the small percentage of the time where I actually use it (like handle one specific exception one way and some other exception differently), I'm not sure if it's worth the overhead. -
Can anyone solve this runtime exception
Hi dudes

Invoking the java compiler from programs
HI, I'm a high school java student in the AP Java course. A project that I have been interested in for a while is making a simple IDE, but to do this I need to compile and run programs from within my program.
What I have tried:
The method Compiler.compileClasses("name of file i wanted to compile");
The method System.loadLibrary(System.getProperty("java.compiler"));
The JavaCompiler class in javax.tools. this is my source code.
import javax.tools.*;
public class CompileTest
public static void main(String[] args)
String fileToCompile ="Test.java";
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
int compilationResult = compiler.run(null, null, null, fileToCompile);
if(compilationResult == 0)
System.out.println("Compilation is successful");
else
System.out.println("Compilation Failed");
After this threw NullPointerExceptions I put the line System.out.println(ToolProvider.getSystemJavaCompiler()); and the output was null.
Any help would be appreciated.
Also, if anyone knows how to run the subsequent class file, that would also be a big helpTo run the program, load the class file with a classloader, which will give you a Class object. You then use reflection to find the public static void main(String[] args) Method object, then use Method's invoke method to call main.
You should deal with any exceptions from the program so that it doesn't break your IDE.
It would probably be a good idea to run the program in its own classloader which you could trash after it finishes running so you don't leave resources hanging around.
And finally you probably need to deal with the case where the program calls System.exit(). That could be tricky. (translation, I haven't the foggiest idea how to handle it but I'm sure its possible).
Also there is the issue of background threads (non daemon and daemon) running after main completes. What ya gonna do?
Runtime.exec() is looking mighty attractive right now.

Constructor undefined runtime exception
Hi all,
This is the java prg which is throwing me runtime exception saying constructor undefined.Do anyone have idea of why its throwing I tried to find but am not..
Thanks in advance

} // end classWhat's probably happening here is, you are compiling using javac 1.4, and running the code using java 1.3. If you notice, RuntimeException in 1.3 doesn't provide a constructor which takes Throwable as an argument. So when the class loads and you call your constructor that takes Throwable and call super(throwable), you get an exception that no such constuctor exists. But it compiles just fine, because java 1.4 RuntimeException has the appropriate constructor
