Hint: MalformedURLException

It looks as though the URL you are using contains some invalid formatting or characters. Take a look at the content and see what is wrong with it.

thx for ur reply.
I want to know how can we read a .tga extension image file using imageIO.read.

I am reading .jpeg file but it is not reading .tga file.

I am doing like this:
String imageFilename = "c:\\sample.jpg";
imageIO.read(new File(imageFilename));

Any Ideas for rading .tga file?

Thanks in Advance
Yogesh

Yes, I looked at Google also and it seems TGA is not supported in native Java. However there were a few links which may offer the answer; I searched on ImageIO TGA Java.

Hello Richard
I found one link that reads Tga file.
It reads pixels into BufferedImage and tht i need.
But while Writing to BufferedImage It is checking for some parameters that doesnt meet from my tga file.Like,it is matching ImageType that doent meet from my file.And If I ignore that condition then it loads tga but in some bad manner image loaded.

Here is the link I msending u.See If u cna help me.
Thanks In Advance.

Sorry, but I don't know anything about TGA, you will have to work it out for yourself using whatever documentation and other tools are available. It's a pity that you are forced to use a file format that does not have widespread support!

TGA files are very widely supported within certain applications, e.g. games, CGI, ray-tracing, things like that. The fact that Java does not support it natively does not mean that it does not have widespread support.

imagetype is part of the standard tga file header. If your file doesn't have this, are you sure it is a valid tga file? (Sorry if that's a dumb question.) Without an imagetype you don't know whether the image is compressed or not so how can you load it?

I want to learn networking projects. So there should be a server and a few clients to test my code. Unfortunately I have only a single machine. Is there any software available for simulating a server and a few clients( or one client) in a single machine?

You don't really need anything special unless you are concerned about the networking. Just set up the server listening for connections and run the client so it will connect to the correct prort on the local host.

Hi,

I have been trying to use Flexigrid(jQuery plugin) with JSP and/or to a Servlet. But I don't seem to find any solutions. I tried to use JSON but it doesn't seem to work. I'm very new to Flexigrid and still getting a hang of it. Can anyone give me advice on what are the things that I should consider? Thanks in advance guys.

Thank you,
Paul

This is no good, you need to explain what is not working, as we cannot guess, and few people have the time to read through your code and work out what is happening. Also this is not a Java question, and would be better posted to the Web Development forum.

Re: my validation form not working - pls advise. tks.

30-Dec-09 6:31

Whenver there's blank, an error message will appear and when the entry doen't meet the regular expression, it will also show error message.

The thing is that both messages will appear even though I just submit without enter anything.

Then I have problem with radio button validation for gender.

Pls advise. Tks.

Re: my validation form not working - pls advise. tks.

Sorry...the reset button is also not working. The netbean IDE keeps on asking to to create an Object.

Richard MacCutchan30-Dec-09 11:01

Re: my validation form not working - pls advise. tks.

30-Dec-09 11:01

This obviously requires some more work on your part, your statement above tells us nothing, your previous statement mentions error messages but you don't tell us what those messages are, or where in the code they occur. We cannot guess what is happening.

karengsh30-Dec-09 16:05

Re: my validation form not working - pls advise. tks.

30-Dec-09 16:05

The form allows user to post their particulars to a table.
Now, when I press submit, it will give me 2 kinds of error messages.
However, it is just supposed to flash 1 error message. It is only supposed to flash another kind of error message when the form does not meet the regular expression rules.

Secondly, the reset button is not working. Netbean IDE keeps asking for object wanted.

Thirdly, the radio button validation I am not sure what is wrong with the code.

Hope you can help me. pls. urgent.

Richard MacCutchan30-Dec-09 23:58

30-Dec-09 23:58

You continue to believe that I can guess what these error messages are - I cannot.
Also if the IDE is asking for an object (where, I have no idea) then I suspect there is something missing from your code.
