    Gregory:
    If you want to upload several Java classes in one script the solution is .sql file, for example:
    set define ?
    create or replace and compile java source named "my.Sleep" as
    package my;
    import java.lang.Thread;
    public class Sleep {
    public static void main(String []args) throws java.lang.InterruptedException {
    if (args != null && args.length>0) {
    int s = Integer.parseInt(args[0]);
    Thread.sleep(s*1000);
    } else
    Thread.sleep(1000);
    create or replace and compile java source named "my.App" as
    package my;
    public class App {
    public static void main(String []args) throws java.lang.InterruptedException {
    System.out.println(args[0]);
    exit
    Then the .sql file can be parsed using the SQLPlus, JDeveloper or SQLDeveloper tools.

  • How to call a Java class from another java class ??

    Hi ..... can somebody plz tell me
    How to call a Java Class from another Java Class assuming both in the same Package??
    I want to call the entire Java Class  (not any specific method only........I want all the functionalities of that class)

    Regards
    Smita Mohanty

    Hi Smita,
    you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
    e.g.
    you have developed A.java and B.java, both are in same package.
    in implementaion of B.java
    class B
                A obj = new A();
                 //to access A's methods
                 A.method();
                // to access A's variable
                //either
               A.variable= value.
               //or
               A.setvariable() or A.getvariable()

  • Re: Using simple java class in an .war file.

    Hi All,
    I have a simple question,
    Can I access an simple java class from a jsp file that I have written by putting it in the "classes" folder?? What entry should go in the web.xml file?
    Here is my directory structure:

    I want to access the simpleJavaClass.class from the jsp test.jsp.
    Please suggest.
    Thanks and regards
    Ayusman

    It is possible to access the class in u r classes folder from u r jsp file.
    For example
    <%@ page import="com.test.service.PricingSolution,
    com.test.core.PhoneNumber
    %>
    <% PricingSolution solution = (PricingSolution)session.getAttribute("solution"); %>
    This is a simple scriplet example. You do the same using jstl tags also.

  • How can i run Java class form  other java application.

    Hi ,
    I have problem to run java class from my java application,
    I am using the class ClassLoader in order to launched the Java class , it�s work fine whenever, the class exist in the same folder , however , when i am trying to run class that is not in the current folder ,
    i got error (see below),
    Do you have any idea what is wrong?
    java.lang.ClassNotFoundException
         at SimpleClassLoader.loadClass(SimpleClassLoader.java:110)
         at SimpleClassLoader.loadClass(SimpleClassLoader.java:53)
         at Run.main(Run.java:31)

    What does "run an class" mean? You don't run classes. They're not executables.
    I bet your problem is the classpath. You are aware that the classloader looks only there? Unless it's an UrlClassLoader.

  • How to combine the classes from 2 jar files into 1?

    Hi there
    I have got 2 jar files with the same name but the classes that they contain are different. So, I want to combine those 2 files into 1. Could anyone please tell me how to add the classes in a jar file to another jar file?
    Thanks for your help!
    From
    Edmund

    The jar utility allows you to extract files as well as put them into a jar. This is in the java docs.
    You might have to hand modify the manifest file if it was hand modified in the first place. All you should have to do is copy the text from one file to another. The manifest will have the same name so you will have to extract to different dirs so it isn't overwritten.
    Steps:
    -Create dir1 and dir2
    -Extract jar1 into dir1, Extract jar2 into dir2.
    -Manually examine manifests and combine if needed.
    -Copy files from one dir to another.
    -Use jar tool to create new jar.

  • Invoking a method from a java class to a jsp file

    Maybe i'm going through a very basic error, but as i've looked for in some forums and nothing found decided to post. So let's go to the problem.
    Well, i have a form in a jsp file, it's basicaly html, but as i need some select boxes populated with data from the database i decided to create some methods in java classes. This is the point.
    My method receive some attributes, like the table and colums names, the name of the select box and the HttpServletResponse object.
    So after making all the database process. The method is supposed to write the result through the out.println(); object
    It goes everything all right except that the method seems to be called first than the html code coz' my select boxes comes above the head in the begin of the page and was supposed to come in the middle.
    part of the code:
    package pacote;
    import java.packages.*
    public class Class{
    public void metodo(HttpServletResponse response, String tableName, String column name, String selectName){
    PrintWriter out = response.getWriter();
    openConnection();
    //After making the query stuff
    //caso n�o haja nada na consulta
         if(rst == null)
         out.println("N�o h� registros.");
         else{
         out.println( "<select name='" +SelectName + "' id='" +SelectName + "' class=\"input_ob\" >");
         out.println( "<option value=''>Escolha: "+objeto+"</option>");
         //fill the select body with options; A while that sweap the resultSet and use the out object to write the results          
         getSelectBody(out,rst, selectValue);
    }This method is called this way:
    <tr valign="baseline">
        <td nowrap align="right">Grupo</td>
        <jsp:useBean id="m" scope="page" class="pacote.Class" />
            <td>
              <%
              try{
                   m.metodo(response, "tabela","grupo","id_grupo);
              } catch (IOException e) {
                   // TODO Auto-generated catch block
                   e.printStackTrace();
                        %></td>I'd like to know what i'm missing here. why the answer doesn't go in the place It's supposed to go.
    any answer will be greatly apreciated

    The issue is caused because you are using the response to get the writer directly.
    The JSP has gotten the same writer, but has wrapped it in a JSPWriter class. That class has got a buffer.
    So it writes the beginning html to the JSPWriter buffer.
    You write your stuff to the response writer - gets sent to the output.
    It writes more stuff to the JSPWriter buffer, then flushes that buffer - at which point all the text written into the JSP writer now gets added to the response.
    You see how your code is coming out first?
    Solution - instead of getting the writer from the response, pass the writer into your method (maybe instead of response if you don't use response for anything else)
    public void metodo(Writer jspWriter, String tableName, String column name, String selectName){
      PrintWriter out = new PrintWriter(jspWriter);
      ...That means that you will be writing to the same writer, and the text should come out in sequence.

  • How to integrate a class with template.java - Java Concurrent Program. 11i

    Hello, I have a java class I got from a vendor. This java class needs to run through as concurrent program. As per metalink note *How To Create a Java Concurrent Program?

  • Unable to import a java class in a jsp file

    Hi,
    I am trying to import a java class in my jsp.
    ------------------jsp---------------
    <jsp:useBean id="form" class="com.company.portlets.searchApps.object.SearchOBJ" scope="request" />
    <jsp:setProperty name="form" property="*" />
    <input type="TEXT" name="projectID" value='<%= form.getProjectID() %>'>
    When I run the above JSP, it says that class 'com.company.portlets.searchApps.object.SearchOBJ' cannot be found.
    Why?
    My project structure looks like this:
    Project
    +Application Sources
    ++com.company.portlets.searchApps.object
    +++SearchOBJ.java
    +Web Content
    ++htdocs
    +++searchappsportlet
    ++++SearchAppsPortletShowPage.jsp
    ++WEB-INF
    +++index.jsp
    +Resources
    ++SearchApps.deploy
    Please advice...thanks!

    The way that JDeveloper organized the files was like this:
    C:\jdev1012\jdev\mywork\WksSearchApps\Project\classes\com\company\portlets\searchAPPS\object\SearchOBJ.class
    I am assuming that JDeveloper puts the file where they are suppose to be...if not, how do I change that?

    }I´ve got Resolutor.class in /res and the other two files (and the rest of the files for running) in /res/tarea.
    If I execute /res/tarea/lanzar.bat from the command line everything works fine, it calls java and runs lanzador without problem.
    The problem comes when I try to execute the batch file via Resolutor.class. It executes the batch file without problem, but it throws a *java.lang.NoClassDefFoundError: Lanzador* when launching the new java application.
    Any ideas of how can I solve that problem. (It must do it via batch file).
