"sanity checker" was not as cool as it sounded.
i imagined some sort of luscher color test + response time checker psychological monitoring system.that wouldn't be nice for the kids as it would give them unexpected (to them) output when they ran it on themselves...

How can we call WinAPI's from java... any idea... its urgent

Hi all,
I am facing a problem, I want to call Win API's form Java. any idea..
Any win API.. like GetUserNameA.... (it fetches current user logged in).
Its bit urgent guys... i have always counted on u guys...
Thx & Regards
@mit

I needed to do exactly this; use getUserNameEx, a couple of weeks back and I asked, then solved it myself and posted my code. A forum search should turn it up,
The only method, of course, is to use JNI and do the call from C.

But if the project requires to learn something new...i wont mind at all. I would really appreciate you guys input about any ideas.

IDE's for Java

I'm fairly new to Java. Ive programmed quite a bit in the past (Pascal, C and C#.NET) - Im at university and I would like to know if there are any free good IDE's. I'd like one with some Debugging tools if possible. I'm currently using Textpad, as its the one we use at university.

IDES for writing Java card applets and converting the applets as CAP FILE.

I have developed a JAVA CARD APPLET , FindMFValueJCA.java . It gets compiles in net beans 6.0 But while converting the applet to CAP file i am getting some errors. Is there any other IDES which take care of converting the CAP files

What's the Java version you are using?
As the java card tool kit has version dependencies. If you are using java_card _kit 2.2.2 then 1.5 is fine.

Web based Java URGENT

Hi,
I am a student developing a software for my final year project. I am developing a reminder system that will send text messages to students mobile phones. I know how to do this coding.
Students would enter their details such as mobile phone number, the name of the reminder such as coursework deadlines, appointments. For this I need to develop a software that users can enter details onto the Web based way. I am not sure where I can start to learn these. Do you have any ideas of where I can start?
The details would be picked up by my software such as the mobile phone number. The text messages will be done through the CLDC MIDP.
Students will enter their details onto the web based way. They will need have to a login.
Do you know what I can learn or what I need to know to get started?

are you looking at a simple java based web application? you can try it with JSP with some forms...a servlet and a few beans...you can authenticate the user login...you need a database....if you don't already have one...
here's a simple design...
1 jsp - login.jsp - 2 fields....user name and pwd - on submit, connect to a database and verify the user (do this by redirecting to a servlet)
2 jsp - form with the required fields like name, subject, assignment, deadline...on submit, just store this in a table..
if this is what you're looking for, I think this simple design should help...

Ideas for deploying Java Applications to the Web?

I am developing a java application which will be distributed via cd and the Web. My first idea was to create the application for cd, then modify it with applets to be deployed on the web. Does anyone else have any better suggestions?

Which is the best and user freindly IDE for developing Java GUI application

Please advice me if there is any good IDE for developing all kind of Java applications.
I m confused about which IDE to use.
I have Searched on Net also. and most of the answers i found was for JBuilder and JBoss.
But cant confirm until u guys suggest me.
Because i think this is the best place to ask questions about java.
Please advice

If you're developing JSPs and Servlets....
I've found that using Eclipse (which is free) coupled with the MyEclipse plug-in (an advanced J2EE specific plug-in which costs $29.99USD/year) was the best for me. I've tried several free J2EE Eclipse plug-ins, didn't like them. Wasn't a big fan of NetBeans either, but I liked it tons better than the other Eclipse plug-ins.
Therefore, IMHO for free I'd go with NetBeans, for a small fee I'd go with Eclipse/MyEclipse plug-in.
If you are new to J2EE but not to Java, you may want to consider going straight to JSF and Sun's Java Studio Creator. This is not free, but the fee is one-time and development is (mostly) visual using Java Studio Creator.

Files creatd in Unix through java, URGENT

Hi,
While creating files in unix through Java, by default created files have only permission:
-rw-r--r--, actually I need full permissions(-rwxrwxrwx ) for the files created through java in unix. Any idea how can we do this?
Your help would be greately appriciated.
Thanks,
Anand

I doubt that you will be able to get execute permissions set on normal files by setting the umask. You may have to use Runtime.exec() to invoke chmod, or call chmod via JNI if it is something you do often.

With JCOP IDE with other Java Card.

Hello,
Can I use any Java Card in the JCOP IDE? Anyone have this kind of experience? If I can do it, then what kind of information do I need?
I'm wondering if it's necessary to buy development tool kits for each java card.
Thanks,
Julie.
