Compile Java class

Hi everyone,
I am new to WSAD env. Can anybody tell me "How I can compile a Java class using WSAD?".After compilation, where does it(the dir structure and location) keep the .class file?
Thanks in advance

In a project I have in WSAD Integration Edition 5.1, a .java file is compiled to a .class file in
/WebContent/WEB-INF/classes/
I'm not sure if that was your question if it relates to JavaServer Pages

  • Suffering an complie error when trying to compile java class in EBS11i

    Hi,
    When I trying to compile java classes with which imported the HttpServletResponse class, will get the follow error message:
    package javax.servlet does not exist
    cannot resolve symbol
    symbol : class HttpServletResponse
    It seems the javax.servlet package is not included in the classpath. But I checked the $CLASSPATH, it seems no problem.
    echo $CLASSPATH
    /u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/lib/tools.jar:/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/lib/dt.jar:/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/jre/lib/charsets.jar:/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/jre/lib/rt.jar:/u02/applvis/viscomn/java/appsborg2.zip:/u02/applvis/visora/8.0.6/forms60/java:/u02/applvis/viscomn/java
    Does anyone know the reason?
    environment: ebs 11i
    Thanks&Regards,

    resolved this issue.
    1. Edit $APPL_TOP/admin/adovars.env file -
    Add the following jar files to the AF_CLASSPATH line -
    Full path of /...../iAS/Apache/Jsdk/lib/jsdk.jar
    Full path of /...../iAS/Apache/Jserv/libexec/ApacheJServ.jar
    2. Bounce the concurrent manager in order to have the changes take effect.

  • Ant or what tool to compile Java Classes

    For the past year I have been using Windows command window to compile Java Classes for my Servlets, Java Beans and Helper classes. I use Cold Fusion studio as my IDE for creating the Java classes. All of my Web Applications use MVC for Forms feeding small databases and I only have around 7 to 10 class files per Web application.
    Should I start to use Ant and/or what is recommended so I can keep up with current technology instead of using Windows Command Window to compile my Java classes?

  • Dynamically Create and Compile Java Classes

    Hi,
    I have a requirement to dynamically create and compile Java classes and would like some advice on the best method to do so.
    Basically the project I am working on involves creating "Factors". Factors are items that have both attributes and weights so for example Factor A could have attribute B with weight 0.76, and attribute C with weight 1.33. There are a number of methods common to all factors such as calculateTotal, identify etc etc.
    At the moment the application has 5 factors, but there is a requirement to dynamically add and remove factors on the fly.
    I current solution I have been considering is using XML to describe the new class, build up the class and compile it; something along the lines of what is descibed at
    http://www.javaworld.com/javaworld/jw-02-2002/jw-0201-xslt_p.html
    however i would like to consider all options.
    Any help with this is greatly appreciated.

    You want to dynamically create and compile Java classes.
    I would try the following:
    (1) Write the Source code of the new class into a text file with the name MyNewClass.java
    (2) compile this new .java-file with Runtime r = getRuntime();
    try {
        r.exec ("javac MyNewClass.java");
    } catch (IOException e) {
        System.out.println("ooops " + e.getMessage());
    } (3) somehow try to load that new class, maybe using ClassLoader cl = ClassLoader.getSystemClassLoader();
    cl.loadClass("MyNewClass");

  • Compiling java classes from JDeveloper

    Hi guys... perhaps this thred need to be created in JDeveloper fourm, it so please let me know.
    I generated the classes from a web service which complie without errors and exedcute correctly. When trying to compile the main stub in Oracle database, I get an error "CONNOT RESOLVE SYMBOL" reviewing the java class, I see that extends the wrapper generated by Jdev. So I try to complie the extendable class, after trying to generate and compile it in the database, I get the error: "class$ is reserved for internal use" The code has the next line:
    static java.lang.Class class$(java.lang.String param1)
    Is this error launched from the oracle database? My guess is that maybe Im missing some library or something and thats why I can create the such Java Name procedures. But I will like if anyone could guide me through this exception.
    Thanks
    JP

    Do you have .jar (or the .class) files created after the compile from JDeveloper?
    If you do, you can load all of them using the command line utility loadjava:
    $ loadjava
    loadjava: Usage: loadjava [-definer] [-encoding encoding] [-force] [-genmissing] [-genmissingjar jar] [-grant grants] [-help] [-nousage] [-noverify] [-oci8] [-order] [-resolve] [-resolver resolver] [-schema schema] [-synonym] [-thin] [-tableschema schema] [-user user/password@database] [-verbose] classes..jars..resources..properties...

  • Compiling java classes into dll

    Hi,
    Just trying to find out is there anyway I can compile the java classes into dll?
    If I am to use JNI and C++, will the dll compiled be able to work well in a platform that does not have JVM?
    Thank you.

    Hi,
    Just trying to find out is there anyway I can
    an compile the java classes into dll?
    No, but you can start the jvm and run your main class from a dll using jni. And, if you do that, you'll of course need a JVM on the client that'll be running your code.

  • Is it possible to get the Source from the Compiled Java Class File?

    Hello All,
    I wrote a java file which uses Java Swing to crea a GUI.I have also compiled the jave file.
    The problem now is that i've made many changes and compiled it many times.Now suddenly due to some problem,the contents of tha Java file have been deleted and it shows 0 bytes.
    Is there any way to recover my Java source file from the Class file?I would be thankful to anyone who can help me out on this.
    Thanks in Advance,
    Regards,
    Vijayakannan

    Yes and no, you can reverse engineer it to an extent, it wont look exactly like your original source though, it'll be full of commented out bytecode bits etc. As its your own code though you've got the best chance of deciphering it. Go to somewhere like www.tucows.com to download the software for doing it.

  • Problem to compile .java class

    hi,
    i'm using/creating a package of classes....and as per my knowledge there is no need to write explicit import if u r importing/using an instance of class1 in other class2 in the same package.....
    I'm doing the same.....
    but the problem arrises here that....while compiling class2 the error occures..........
    D:\tomcat\webapps\Books\WEB-INF\classes\BookForm.java:6: cannot resolve symbol
    symbol : class Book
    location: class BookForm
         private Book book =new Book();
    why so????? as i have included the package in CLASSPATH also..........
    PLZ reply....
    .....Amita

    You don't need to import classes that are in the same package but they do need to be in the classpath. My guess is that you are compiling BookForm.java from the D:\tomcat\webapps\Books\WEB-INF\classes directory. Either add "D:\tomcat\webapps\Books\WEB-INF\classes" explicitly to your classpath or add a dot (".") to your classpath.

  • Cannot compile java classes error

    After mimicing the 'Add the databse exception handling to the FulfillOrder process' in my prototype when I attempt to compile it I get the error 'Error: Failed to compile classes.
    Failed to compile the generated BPEL classes for "providerEnrollmentMain".
    What I am supposed to do with this error?

    The prototype is Medicaid provider enrollment. A doctor who wants to serve Medicaid patients must be enrolled with the state to receive payment for services. The prototype is a self-service enrollment. It is already fairly sophisticated with 6 services being called by the main flow. I recently added a DB write activity and then proceeded with the DB exception handling example from the OrderBooking tutorial. The error occurred then.
