How to compile my java?

How i compile java? when i open javac, it closes in less than a second...

Make sure that , the CLASSPATH and PATH variables are set in a proper way in Environmentvariables in your system if you are using WINDOWS.
CLASSPATH=%JAVA_HOME%/lib;
PATH=%JAVA-HOME%/bin;
then you have to check in commandprompt by simply typing 'javac'.
if you get the Options, then it is working properly.
hope this may help you.

How to compile a java file which is in memory?

how to compile a java file which is in memory?
such as:
String s="class MyClass {....}";
how to compile the string?
thx

come on ...That was a perfectly valid solution.
Do you know how to call the sun.* compiler? If not then search the forums for it. If that interface still exists (which it might not in newer versions) you then will create a string stream from your class and pass it to that.

You'll need to add the j2ee.jar to your classpath. Usually you'll have to add some jars from your app server to your classpath as well.
For example (using weblogic):
javac -classpath c:\java\j2ee\j2ee1.3.1\lib\j2ee.jar;c:\tools\appserver\weblogic\wl7.1\lib\weblogic.jar
HelloServlet.java

How to compile a Java file

Hi All,
I am extending a seeded CO and when I try to compile it in JDev , it asks for many class files the seeded CO imports.
I have copied all those imported files to my local system and when I try to compile , it still throws an error that some class files used by the classes imported in seeded CO are missing. Now this goes on and on. ( Seems entire server needs to be on my local system).
Now I decided to port the custom CO to server and compile it there. Even this seems to be a hard task for me as the javac command is not working on the server. It throws following exception
Exception in thread "main" java.lang.ClassFormatError: com.sun.tools.javac.main. Main (erroneous method access flags)......................................
Pls suggest how to compile a java file , as downloading entire server classes is a herculean task for me.
Thanks,
Srikanth

Hi Avajain & D.Ram ,
Thanks for the reply.
I have downloaded around 70 dependent class files to local system. Now the CO is getting compiled correctly.
I am extending a region level controller in Payroll page where in I have to default the salary to a predefined value.
This field is having a VO attribute to it. Now can I go ahead and set a value to the MessageTextInput or should I extend the VO to replace the desired value in the place of already queried value.
Thanks,
Srikanth

How to Compile Servlet Java Files

hello ...
i am a beginner at JSPs and java servlets ... i have been searchin' hopelessly for the past couple of days. Could someone please guide me on how to compile source files for servlets ... namely how can i include the packages javax.servlet.* since the compiler gives me an error that there is no class name ... I am using jdk1.3
Do I need to get the java server development kit ... but i cant seem to find it any where on the sun's site ... and do i need to download the j2ee sdk too ...
As you can gather that i am completely comfused and lost ... After doing programmin with asps and previous java experience, i had thought that the migration to a java platform on would be a breeze but the lack of any solid documentation which addresses the above questions is dampenin my spirits ... and the cryptic documentation with tomcat doesnt help either. :)
pleaze reply soon ... i have to implement a project for my company ... otherwise i would have to put servlets and jsp back in the closet and return back to asp.

Try http://java.sun.com/j2ee/docs.html specifically, the links on that page called Download Instructions, Installation Instructions, Java Servlets Tutorial and JavaServer Pages QuickStart Guide
By the way, J2EE SDK's reference implementation is based on Tomcat itself but is more than a web container.

heyall, just placed the following java code in my src folder in my web app folder in netbeans, anyone tell me how to compile this now?F9
it asks me for a main but not sure exactly what to putCompiling source files never 'asks .. for a main'. You must be trying to execute it. You can't do that outside the servlet container it is intended for
COMPILER ERROR - package javax.servlet.http does not exist
BUT can't even get this far yetSo try compiling it as per your tutorial. Do you understand the difference between 'compile' and 'run'?

How To Compile Within Java

Hi Everybody,
I have a serious problem. I want to compile a Java file withing another Java program, without using the "javac" command or this compiler. Is there any function or class which helps compile a Java source file created withing another Java Class file, So that the new Java source file will not be available to the outside world?
Thanks,
TechnoSam.

I'm pretty sure that you can create a class in memory by passing it a stream of bytecode. From this you could create a new instance and then proceed as normal. However, you're going to need to know how to create that bytecode and I guess that you don't want to have to implement a 'virtual' compiler from scratch. I don't know of anything that can do this for you but I wouldn't be surprised to find that somebody's had a go in the past.
Perhaps your requirements would be satisfied by compiling your dynamically created source using javac to a temp file and then deleting that once you had instantiated the object? This would do something like what I think that you're after but even then you would need to accept that others would be able to access your class definition by reverse-engineering your source-writing routine, (whether or not it was obsufacated).
Can you say anymore about what you're trying to achieve?
