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.

  • How to compile a java file(Servlet) in J2EE v1.3.1

    This is my first time using J2EE instead of J2SE!!HOw to compile a java file in J2ee\bin because there is no javac in j2ee and when i compile in J2se i got
    G:\j2sdk1.4.1_01\bin>javac HelloServlet.java
    HelloServlet.java:2: package javax.servlet does not exist
    import javax.servlet.*;
    This mean it doen;t support servlet in J2se!!so how can /what command to compile a servlet java file in j2ee.Thanks

    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 which is in memory?
    such as:

    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.

  • 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 other java files and run them from my own programs?

    I'm developing a unit testing tool for AspectJ, which can originally generate the stubs for aspect unit to be tested. All these stubs are java files. After generation of stubs, how can I program the code to compile this unit together with these stubs, i.e. how can I put the functionality of compilation and run, e.g. command "javac *.java" and "java *", into my own code.
    Hope you can understand what I mean.
    Thank you in advance.

    When I use Runtime.getRuntime().exec(command) for executing the AspectJ compile command "ajc", "IOException createProcess error=2" always occurs, while it is ok for Java comiple command "javac".
    Why this happens when I use Runtime.getRuntime().exec("ajc Hello.java Test.aj")? Is it the reason that Runtime.exec(String) may not support any command in DOS?
    (ajc is the compile command for the java file and aj file.)
    Thank you in advance.

  • How to compile ALL java files in OR UNDER a given directory?

    G'Day Folkies,
    At face value, TikeSwing looks like the money shot for enforcing MVC in my version of minesweeper http://forum.java.sun.com/thread.jspa?forumID=54&threadID=5248903
    I'm attempting to build the "Hello World" example which comes with TikeSwing.
    http://www.javaworld.com/javaworld/jw-06-2005/jw-0620-tikeswing.html
    It compiles ok
    C:\Java\lib\tikeswing-1.5\example\src\fi\mmm\hello>javac -d C:\Java\home\classes -cp C:\Java\lib\tikeswing-1.5\src;C:\Java\lib\tikes
    wing-1.5\lib\commons-beanutils.jar;C:\Java\lib\tikeswing-1.5\lib\commons-lang-2.0.jar;C:\Java\lib\tikeswing-1.5\lib\commons-logging.
    jar;C:\Java\lib\tikeswing-1.5\lib\log4j.jar;C:\Java\lib\tikeswing-1.5\example\src;. HelloApplication.java
    Note: Some input files use unchecked or unsafe operations.
    Note: Recompile with -Xlint:unchecked for details.
    But it doesn't run
    I presume that javac isn't detecting all dependancies, presumably because Tike "decouples M from V from C" using reflections.

    Thanking You for any thoughts. Keith.

    FYI.... Here's the quick and dirty, slower than a wet week, ugly, but effective batch script
    set TIKE=C:\Java\lib\tikeswing-1.5
    set SRC=%TIKE%\src
    set LIB=%TIKE%\lib
    set CLASSPATH=%LIB%\commons-beanutils.jar;%LIB%\commons-lang-2.0.jar;%LIB%\commons-logging.jar;%LIB%\log4j.jar;.
    FOR /R %SRC% %%f IN (*.java) DO javac -d C:\Java\home\classes -cp %CLASSPATH% %%f
    @ECHO OFF
    REM http://www.robvanderwoude.com/ntfor.html
    REM Walks the directory tree rooted at [drive:]path, executing the FOR statement
    REM in each directory of the tree. If no directory specification is specified
    REM after /R then the current directory is assumed. If set is just a single
    REM period (.) character then it will just enumerate the directory tree.I can't figure out how do the equivalent of javac `dir /s /b *.java` (ie: cmd doesn't seem to have a built-in facility for expanding the results of a command into the command line) which would be a lot quicker and cleaner.
    Cheers all. Thanx for the help. I appreciate it.

    JSPs are compiled into servlets automatically and those classes are stored in WEB-INF/classes folder. Servlet engine handles servlets.
