Still nothing.
I'ved tried the following:
this are all in the class constructor that extends JFrame
1)
add(new MyComponent(0,0,50,50,12));
add(new MyComponent(100,100,50,50,12));
2)
this.getContentPane().add(new MyComponent(0,0,50,50,12));
this.getContentPane().add(new MyComponent(100,100,50,50,12));
this.repaint();
and only the second component was drawn in both cases. However if I omit comment the second component, the first one is drawn correctly.
My component extends JComponent and overrides paint method by painting a image at the specified coordinates.

Hi:
I am deploying Glassfish 2.1.1 with J2EE 1.4. The project compiles-builds successfully. But it fails to deploy and open in the browser. The error from the log is:
com.sun.enterprise.config.ConfigException: I/O error while loading deployment descriptor for: hello2
caused by
Caused by: java.io.FileNotFoundException: C:/eepassion/UnZip/servletbasics/samples/hello2/build/web
I have looked in the web folder and there is an web folder. But do not know what I'm looking for. Your suggestion would be very helpful.

The message seems fairly clear, Java is looking for a file or directory which does not exist, as described in the message. Or possibly there is a permission issue and the program cannot access that folder.

often seen since Windows7 - check if your SDK/involved Programms is marked "run as Admin".

what is the equivalent package on swing in j2me
Trioum

J2ME has within it's framework its own set of controls that are desogned for generic mobile devices. If you are targetting a specific platform then you will also find that there are platform specific UI components. Check the JavaDoc for details.

Since this is the Java forum I suggest you post this elsewhere - possibly either JavaScript or PHP.

Help me with java code for dividing a text file into variable size chunks using Rabin finger print and sliding window technique..
Consider a file .
A fixed width sliding window (48 bytes long) will be moving along the contents of the file.
The fingerprint of the contents of the window is found using Rabin finger print algorithm
f is fingerprint( Hash value) of the contents of file
D be the average chunk size,
r be zero
Position where f mod D =r satisfies at that position chunk a file.. Advance the sliding window Continue this till the end of file.

Where are you stuck exactly ? Nobody here will send you the full code of your program (specially when it looks like homework question).

Hi,
I have 3+ years of experience as a software Engineer in Java,J2EE concepts ,
developing the web-application and ERP domain modules,
I have currently offer in two companies for separate in two different domain
projects. Below are the details...
Offer 1 - The role is of an engineer in developing the web-applications
using J2EE concepts (springs, hibernate,and JSF) Client --Reddy Labas
Offer 2 - The role is of an engineer in developing the projects using the
tool called Identity Management (J2EE concepts as backend) Client-JPMorgan.
I am little confused to choose which offer and how it is going to be the
best thing in my career /future (job Resources) view.
Am seeking your valuable inputs on which one would be a better offer.
Thank you!

Per this description you would be using Java and associated common frameworks and idioms.
krishnareddy036 wrote: Offer 2 - The role is of an engineer in developing the projects using the

Per this description you would be using a specific vendor tool.
Thus in terms of a career in programming the first is better.
However there could be other criteria.
For example do you want to remain a programmer? If not then which position seems to allow a better chance to move into management?
Another example do you want to use other languages? If yes then which job is more likely to allow you to do that, for example is one more likely to allow you to learn SQL?
You might also want to look into what stage the project is on that you would be working on. Maintenance programming on an existing project for someone with your experience might not be as enjoyable as a new project or one that is relatively new. Along those lines you might ask, of both companies, what additional programming possibilities might exist in a year from now.

From what I think I read in your question, you want to do Ajax. This will allow you to put a request out to the servlet and process the result with Javascript inside the HTML without changing the actual browser page. Try jQuery to get this to work.
If you do not know what Ajax or jQuery are, you first need to do some reading. There is enough info on this on the internet.
