Java J2EE coding help

I would need to know how to set up server or something to get my java code working next to my website without needing access to that website.
(I have Java code to create game coins in my java game on my site but I don't know how to get it working without needing to access to my website to store code there.)
1) I haven't put my game up yet so unfortunately you can't see it online
2) I have java code to create coins inside my game.
3) It doesn't work because I don't know what to do after I have coded it.
4) How to make it work without needing access to my site?

It would be alot easyer to use my code from outside
then from web and from outside it's secured so even
if someone gets inside my website then they can't get
code ; )Have you thought this through? What are you going to do to make your code more secure on your PC than it would be on some other server? How do you plan to facilitate communication between your app and the web server?

Help on java/j2ee application development framework

hello java-gurus,
I'm new to java and is working in java for just 15 months.i want to know more about the platform/framework which is used in the development of java/j2ee projects.To be more specefic i want to build a java/j2ee project .
-->The project will be located in the eclipse workspace.
-->The eclipse will be connected to the cvs and will save the latest code in the repository.
-->The project will have a build.xml file which on being executed
will check the latest code from cvs.
will run j unit test.
on success from the junit it will compile the project.
It will make a .war,.ear etc file..
It will then be deployed in the application server.
So i want to make a framework of this kind.So i want help from u guys how to proceed.
I'm just a starter with ant scripts .know how to clean,build and make war files ..I also know about eclipse like connecting to cvs,generating ant script from it etc..
i'm also comfortable with struts,java,servlet etc..
So do give me some guidelines how to proceed .
thanks

Hello,
i'm working in project same style of what you want. here are details :
- eclipse for development - lomboz plugins for j2ee support.
- using subclipse plugin for svn support checkout and commit, in case of cvs i think it is default in eclipse.
- the framework is Struts, which is a very very powerful J2EE framework.
- eclipse plugin lomboz supports creating and deal with struts project
it also offers GUI for configuring struts xml files.
- lomboz contains plugin for creating and define application servers and containers like tomcat and jboss, so you can compile, run and debug your code from your eclipse.
- i use many other tools for creating UML diagrams and ERD diagram and reflect contents to existing projects.
i think with struts,eclipse and lomboz you need nothing else.

How to develope DVD/burner in java/j2ee

Hi, how to implement dvd/burner in java/j2ee which site , api provide help me

HTML/Java/J2ee IDE / Dev WEB app

I am creating one web application using Java/J2EE. My web page would contain menu and sub menu system.
I have to use HTML/JSP/Servlet/EJB/SQL Server.
For HTML I am using dream weaver and for java code notepad.
I want to use some GUI tool to develop this application.
1. GUI for developing HTML page and text editor for Java code with drag and drop facility for HTML and JAVA/J2ee both with easy integration between these two technology components.
Or
2. Any single GUI tool which provide HTML and JAVA/J2EE editor and drag and drop facility for HTML and JAVA/J2ee both.
Please help me by suggesting!

Now, with all this added complexity, what was the
point. I kinda thought it was to create a standard, so
that deployment was easy.I agree that deployment is not as easy as you would like it to be. However most of this added complexity is to handle situations consistently. And nowadays there are plenty of tools available (my Company makes one), which can simplify the deployment.
Can anyone out there tell me why we should conform to
these standards if the web app servers
won't!!!!!!!!!!!!!!!!!!!!!!!!!That is not how it should be, I agree. While building OptimalJ (the tool we make)we experienced differences between app servers as well. However again, there are tools which make this easier for you (although I don't think they solve it completely yet...).
Hopefully we end up in a situation where all EAR files can be interchanged more easily.

Michiel.

IKM Java J2EE Test

I am about to take IKM Java J2EE test ! If anyone has taken this up before kindly share me the
topics and your experience regarding same ?

Hi Guys,
I thought I will share IKM experience, for people who are planning to take.
I have just finished doing an IKM Exam, 10 minutes back. Overall, I have done four IKM Exams, this year, and two of it in the last one week..
1. Distributed Programming
2. XML
3. Java2 Programming
4. Java2 / J2EE Programming.
You are expecting a tough exam. Atleast, it was tough for me, all of them :)
Exam Pattern:
It is objective based with three possible answers, but not always and does not say how many answers / question, either. Credit is provided as long as you are able to get close to the answers. Say two answers are correct out of 3. Conversely, you have deductions in credit, if you blindly choose anything irrelevant. (that proves absolutely no knowledge in that area) .
You cannot go back to a question, that you have answered already
Questions are made increasingly difficult, when you are answering good and if you find an easy question, all of a sudden, you already know how you have been answering the previous question.
Questions:
On average, you have around 30 - 40 questions and the time limit is 90 minutes maximum. Expect plenty of code based questions.
Syllabus: I do not know if they provide any definite syllabus beforehand and the questions are from all possible areas inside the topic. e.g., when I did the xml IKM, the questions were from XDR, Xpointer, XLink, Xquery and all sorts...
Test Results: The test results shows you are overall percentage. It shows your strengths on each subtopics related to the exam, on three grades (Strong,Proficient,Weak)
You can see your test results, if the test organiser has set up that way. I had an opportunity to see only for Java 2 Programming. So added the topics below
Java 2 Programming: Usual Java (fundamentals,package,i/o,operators,threads., etc.,) + JVM Memory Management + Security Framework + AWT
Hope it helps.

Image size and mime type.. non-java guy needs help

Image size, mime type.. non-java guy needs help
Im not at all familiar with java so this is really weird for me to work out. I?ve been doing it all day (and half of yesterday).
Im trying to write a custom clodFusion tag in java that gets the width, height, size and MIME types of a given file. I?ve been trying to get it to work on the command line first. I can get the width and height but cant get the size and the MIME type.
Here is what I got
/*import com.allaire.cfx.*;*/
import java.awt.image.renderable.*;
import javax.media.jai.*;
import com.sun.media.jai.codec.*;
import java.io.*;
import java.util.*;
public class ImageInfo {
private RenderedOp image = null;
private RenderedOp result = null;
private int height = 0;
private int width = 0;
private String type = "";
private String size = "";
public void loadf(String file) throws IOException
file = "80by80.jpg";
FileSeekableStream fss = new FileSeekableStream(file);
image = JAI.create("stream", fss);
height = image.getHeight();
width = image.getWidth();
System.out.println(height + "\n");
System.out.println(width);
System.out.println(type);
public static void main(String[] args) throws IOException {
ImageInfo test = new ImageInfo();
test.loadf(args[0]);
can anyone please help me out to modify the above so I can also print the mime type and the file size to screen.
thanks for any help

any suggestions?

IMac: Install Java 7 need help!

Hello, I've an iMac with the newest software version, I want to install java 7 on it for a game server, but when I download it from java.com and I install it and start the server, it still says: Computer on java 6, update to 7 to run server. I already tryed to install with Terminal and direct acess to System Library, it shows that java 7 is installed, but I have to delete java 6. When I delete all java versions, apple says I have to install java SE6, what isn't java 7 but java 6! Help please!!!

The Oracle JRE is only a web plugin. If you need server-side Java, you'll have to use the Apple-supplied Java 6 runtime, or else the Oracle JDK (which is not a drop-in replacement for Apple's Java.) If your server application depends on Java 7, you'll most likely have to run it on another operating system.

Oracle ADF/BC4J vs "other" Java/J2ee technologies. Influence a decision

Dear All,
Our dev group is now at the stage when we need to make a decision which way to go - "proprietary" Oracle ADF/BC4J route or open source/java/j2ee standard. In our group we have a mix of Oracle Foms, pl/sql and java developers. The problem is that our core java developers are strictly against any proprietary thing, and they do not really want to even take a look at ADF/BC4J claiming that when it comes to resolving performance and other issues we will be better off with open source, rather than depend on Oracle...
I am coming from an Oracle centric world, and to me ADF is a natural choice, however I do not have a lot of experience in Java/J2EE to post a strong argument for or against ADF and BC4J.
I am just wondering if there is a case study, or comprehensive cons and pros for one or the other path.
I will greatly appreciate anyone's answer.
Thank you,
VO

"When it comes resolving performance and other issues we will be better off with open source."Really? How - are they planning to go into the hibernate/spring engine and fix the problems? Or do they have a specific "support" contract with some company that will guarantee them fixes to these issues? If they do have such a contract how much does this support costs the organization?
Where is the notion that open-source is faster coming from? Certainly not from actual benchmarks like this one: http://www.spec.org/jAppServer2004/results/
As Frank said your management might want to look into a more complete picture than what your Java developers are looking at.
For example, given that you have Forms based developers, how fast can they get up to speed with the open source solution vs the ADF solution?
I think a simple benchmark of productivity when building an application with the stack they are offering vs the ADF stack would prove the point even better.
Don't have time to run one have a look at the RAD Race results from this year where ADF based team beat up Spring based teams.

Can I export from Muse cc with out java script coding?

How can I export from Muse CC with out Java Script Coding?
I'm trying to create an custom email but email won't recognize Java Script, Only HTML.
How do I export my tample from Muse CC using only HTML coding?
Thanks in advance.

Hello,
It is not possible to selectively export only part of the code for the exported page(s). The pages that are exported, all the code for them is exported, and there's no way to export only the HTML and leave out the rest of it.

MS SQL Server in Java/J2EE Environment

Dear all,
I wanted to understand pros and cons of choosing MS SQL Server in Java/J2EE environment.
Could anybody share some thoughts or web resources?
Personally I hate using MS SQL Server for Java/J2EE based applications. But one of my clients wanted to have following environment for his production environment and he insist on using this environment for application development. So I just wanted to understand pros and cons of J2EE (Application) + MS SQL Server ( rdbms )
MS SQL Server
J2EE/Flex
Windows OS

Thanks duff,
The driver seems to be found
when I run
public class t {
public static void main (String[] args) {
try
System.out.println("Hello, world!\n");
Class.forName("com.mysql.jdbc.Driver");
System.out.println("MySQL Driver Found");
catch (ClassNotFoundException e)
System.out.println("MySQL Driver NOT Found");
e.printStackTrace();
I feel somehow ive been focusing in the wrong side of the problem due to my ignorance in Java. Please help me to understand, the reson for which ithe runtime was telling me that there was an unhandled exception was because it is a requirement to handle all exceptions of this kind? why wouldnt it cmplain if I jst did the hello world without any exception handling, maybe because it is a requirement in the Class.forName...
the other question is, is the message I was obtaining completely independent of the fact that the class was or was not found?
Maybe, I should go with these questions to the newbies forum...
thanks
