JSP + internal java class

Hi,
I have a small problem with my JSP, which is using an static internal class as a bean. The oc4j cannot find it. The code is working superb in the Tomcat, but not in the oc4j. The package can be found because the mother class of the internal class is used by other part of the application, but not this one.
My environment:
Windows XP prof (eng)
oversion.cmd delivers following info:
Oracle BPEL Server Version 10.1.2.0.0
Build: 1442
Build-Dauer: Fri Apr 29 16:59:32 PDT 2005
Build-Typ: release
Quell-Tag: BPELPM_10_1_2_release_branch
and this is the interesting part of the JSP
<?xml version="1.0" encoding="UTF-8"?>
<%@ page contentType="application/x-java-jnlp-file" info="My Test GUI" language="java"%>
<%@ page import="lucom.util.HTMLUtil"%>
<%@ page import="oscisigner.OSCISignerImpl.OSCIContainer"%>
<%@ page import="oscisigner.OSCISignerImpl"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<jsp:useBean id="container" scope="request" type="oscisigner.OSCISignerImpl.OSCIContainer" class="oscisigner.OSCISignerImpl.OSCIContainer"/>
The class OSCISignerImpl contains the class OSCIContainer and both classes are contained by the WEB-INF/classes folder (with package of course).
Has anybody a clue why oc4j cannot find it ?
Best Regards
Tomasz

Tomasz:
I have reproduced the problem: <jsp:useBean id="container" class="test.Outer.Inner"/> does not work in oc4j, where Inner is a public static inner class of class test.Outer. This problem will be fixed.
In the mean time, it is a good idea to make your inner class a 'standalone' class since you planned at least to use it independently of the outer class.

  • Jsp page - java class binding

    Is there any configuration file that binds the jsp page and the java class? I need to replace some jsp pages and their classes in different packages, but the pages cannot find their classes. Does anybody know where/how I can set the appropriate binding?
    Thanks,
    Kelly.

    It's not configurable (yet). The page name, and the "backing bean", must have the same name (including case), and the java class needs to be in the package folder with the rest of the backing beans.

  • Managing JSP files (.java, .class) size in working directory

              Our new web application automatically generates JSP pages which
              causes the working directory holding the JSP files to grow
              too large to manage,does Weblogic have a alternate way to
              compile JSP without permanently storing the .java, .class files
              on disk.
              Maybe in cache were they can be managed, cleaned up similar
              to how a database cache works.
              Any ideas or advice would be appreciated.
              THANKS IN ADVANCE.
              

              Just don't look in the classfiles directory and everything will
              be fine.
              WLS will only leave the .java files if you ask it to keep them (keepgenerated).
              If you don't keep the .class files on disk then WLS will have to
              recompile them every time it is restarted. If you have so many
              JSPs you are having trouble managing them, you definitely don't
              want to recompile everytime you restart WLS.
              Last time I looked in our public_html there were 67000 JSP files.
              We don't have any problems managing them.

  • JSP with Java Class

    How to run *.class in JSP. For example, the demo class, Clock.class is run in html format, Can I run the Clock.class in JSP format?

    Please notice,
    The applet has a graphical context which can draw lines, circules and painting all the object including the background. Now the applet can be load from a jsp page also as if it resides on a html page. Now when you want to use the class Clock.class as a bean inside the jsp page, it has to keep the following definition ( you can't get the graphical context from the applet as a class method in a bean.
    The JavaBeans is realy nothing more than a class that maintains some data ( called properties) and follows certain coding convention ( getXX() setXX()) and it has to implements the Serilizable interface and provide no argument for the constructor.
    As a result when you want to use the jsp tag for Bean like <jsp:useBean id="MyClock" class="Clock.class" /> keep in mind that the Clock.class is directly located in /WEB-INFO/classes/ in your web application directory.
    Now your purpose will be directly oriented to get or set some value for the clock like to get the current time or to set different time zone or to calculate the time in Kurdistan if you are in US etc..
    So the Clock class has become a source of hidden business logic operation exposed by methods only.
    The graphical animation etc.. is not related to Bean at all event though the applet implements the Seriazable interface

  • Custom Java class called from RTF template generates error

    We are running a report in BI Publisher and the report calls a custom developed Java class that is used to bind PDFs together and sent the result to another application.
    On the RTF template we have some XSLT that reads the input XML and sets a variable which is then passed to the Java class. We are however getting the following error when the report is called simultaneously 2 or more times:
    XML-22044: (Error) Extension function error: Error invoking 'JavaClassName': 'java.lang.Error: Cannot interweave overlay template with pdf input, combined number of pages is odd!
    I read this as the real cause of the error is the Java code but I'm not 100% sure. Also I don't understand what the error message means.
    Could someone help out please?
    Many thanks

    Since our this requirement is in Quotes module, its not using OAF. It is using plain JSPs and java classes.
    What i was thinking is, create the Option values as flex fields, and write a custom java class to fetch these data from the flex tables and use it in the JSP.
    The main problem we are facing now is,
    "...we wrote a simple java class, which establishes database connection, executes a simple insert & select query to our custom table. compiled & placed the class file under our new pkg structure under $JAVA_TOP eg. oracle.apps.xxx.quot.tmpl , bounced the apache."
    But when we tried to import this class in the jsp (which is being customized), the app just throwed Internal Server Error and we couldnt find any info in the Log file.
    Couldnt guess, why is this simple thing failing. Any idea ?

  • Custom java class in Quoting screen Customization

    Hi,
    We are working with Customization of couple of screens in Quote module. Esp. the Create Template screen. We decide to add new property to the Template and user needs to choose among a set of values to this new property through a radio button.
    Instead of hardcoding these property values and radiobuttons, we thought we would define these data in some lookup table and fetch them and display.
    Now, since we are defining these lookup data, should we write our custom java class to interact with database and fetch them from any lookup table (should we use flex fields ?) ?
    If we are going to write custom java object, any guidance on how to compile/deploy/standards for them ?

    Is that Jasper Exception telling us where the problem is in the jsp, though?
    If it is, then "rs" is null in the call rs.next()...which means conn.executeQuery() is returning null. Which means that whatever class conn is (news.conn?) has a problem maybe?That's possible. Though, it may just be the case that the 'conn' object itself is null! That line is the first place where it's being used and there are no checks that I can see...we'll have to wait for the OP to investigate and reply I guess.That's what I originally thought, then I noticed it was saying line 47, which is the rs.next() line. Assuming Jasper is correct in its choice of line, then it's the rs that's null. Which means the conn is doing strange things.
    Edit: Now that I think about it, going by the previous thread the OP posted, I'm wondering whether news.conn class is their attempt to move the JDBC stuff out of the JSP page, and it's grabbing the "real" connection (java.sql.Connection) and getting the result set and returning it...or getting something wrong and returning null.

  • How to invoke a 6 parameter java class within jsp

    i have just begun to learned jsp and java recently, so have the question below:
    Situation:
    My boss asked me to do a project for doing online data mining.
    He requested the thing below:
    1. Write a webpage by jsp with some textfield or pull down meun to get the parameter for getting the opinion and the parameter needed for the java class.
    2. When the user click the buttom in the website, then the java class have to be invoked.
    Questions:
    1. ask i put the .java in the server, i can simply use cmd and type the following command:
    java -Xmx800M P05context 1 1 3 6 F01xyz.txt F10xyz.txt
    which F01xyz is the prepared text file for the java class to read and the F10xyz.txt is the output file generated by the P05context.class
    but i don't know how to invoke the P05context.class by jsp
    My boss have suggested me two ways to do this:
    a. write a java virtual class to execute the java program.
    but i don't know how to write.
    i think conceptualy will be like this :
    public class run_java
    public void run java(parameter1,parameter2....,parameter6)
    //run the cmd command
    //java -Xmx800M P05context 1 1 3 6 F01xyz.txt F10xyz.txt
    b. write a javabean in the jsp. and i have try to use this code(at the end of the message:
    but the tomcat server reply a internal error to me
    how cani do ?
    the jsp file-->
    <jsp:useBean id="test" scope="session" class ="P05context" />
    <html>
    <head></head>
    <body>
    <% test.P05context(1,1,3,6,F01xyz.txt,F10xyz.txt); %>
    </body>
    </html>

    I still don't see why the form (the origin of the request) has to be a JSP, As you say, it might be static but forms I've written have usually had some kind of menu framework arround them and other variables. Also if the input is invalid you usually want to re-present the form, with an error message and the fields pre-populated according to what the user put in before. That does require a JSP and you may as well use the same JSP for an empty, as for a rejected request.
    the response to the form should be handled by a servlet. Both is HTML, but the
    form is static, and the reply dynamic. Using the combination; a servlet to do the data processing and a JSP to format the results is more flexible in a number of ways. For example, suppose you find the need to present the data form in, say, Greek? You don't want the processing to be duplicated in English and Greek versions of the results JSP.
    Suppose the boss wants to turn a graphics designer loose on your HTML. Don't want him mucking about with your processing code do you.
    The servlet typically takes the function of controller in the model/view/controller paradigm.
    Code in a servlet is cleaner, better formatted and easier to access with a debugger.

  • Using java class and variables declared in java file in jsp

    hi everyone
    i m trying to seperate business logic form web layer. i don't know i am doing in a right way or not.
    i wanted to access my own java class and its variables in jsp.
    for this i created java file like this
    package ris;
    import java.sql.*;
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.SQLException;
    public class  NewClass{
        public static void main(String args[]){
            Connection con = null;
            ResultSet rs=null;
            Statement smt=null;
            try{
                Class.forName("com.mysql.jdbc.Driver").newInstance();
                con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
                smt=con.createStatement();
               rs= smt.executeQuery("SELECT * FROM emp");
               while(rs.next()){
                String  str = rs.getString("Name");
                }catch( Exception e){
                    String msg="Exception:"+e.getMessage();
                }finally {
          try {
            if(con != null)
              con.close();
          } catch(SQLException e) {}
    }next i created a jsp where i want to access String str defined in java class above.

    Very bad approach
    1) Think if your table contains more than one NAMEs then you will get only the last one with your code.
    2) Your String is declared as local variable in the method.
    3) You have not created any object of NewClass nor called the method in JSP page. Then who will call the method to run sql?
    4) Your NewClass contains main method which will not work in web application, it's not standalone desktop application so remove main.
    Better create an ArrayList and then call the method of NewClass and then store the data into ArrayList and return the ArrayList.
    It should look like
    {code:java}
    package ris;
    import java.sql.*;
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.SQLException;
    public class  NewClass{
        public static ArrayList getNames(){
            Connection con = null;
            ResultSet rs=null;
            Statement smt=null;
            ArrayList nameList = new ArrayList();
            try{
                Class.forName("com.mysql.jdbc.Driver").newInstance();
                con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
                smt=con.createStatement();
               rs= smt.executeQuery("SELECT * FROM emp");
               while(rs.next()){
                nameList.add(rs.getString("Name"));
               return nameList;
                }catch( Exception e){
                    String msg="Exception:"+e.getMessage();
                   </code><code class="jive-code jive-java"><font>return nameList;</code><code class="jive-code jive-java">
                }finally {
          try {
            if(con != null)
              con.close();

  • How to convert a .jsp to a .java/.class file for use in peoplesoft

    Hi java/jsp experts,
    I want to convert a .jsp to a .java/.class file. is there a tool available, please let me know if you have any pointers....
    or can i do it manually:
    these are a few lines that the .jsp contains, and i would like to translate this to be in .java/.class format:
    <%@ page import="sun.misc.BASE64Encoder, javax.crypto., javax.crypto.spec."%>
    <%@ page import="java.util.StringTokenizer" %>
    <%@ page import="java.util.Map" %>
    <%!
    sb.append("<input type=\"hidden\" name=\"orderPage_serialNumber\" value=\"");
    sb.append(serialNumber);
    sb.append("\">\n");
    return sb.toString();
    %>
    how can i translate the above import statements and html elements from jsp to java, please let me know.
    Once i have the .java file created from the .jsp, I will compile .java to create the .class file and invoke the .class in peoplecode by using java apis available in peopletools.
    Thanks in advance.

    Is there a way convert a binary .exe file( compiled by
    another compiler) into Java .class/.jar file ? Anyone
    know of a free program that can do this?It's not possible. There are many decompilers and disassemblers for Java but nothing will take you from ANY binary to Java source. It would be the end of computing as we know it and the beginning of a new era -:)

  • How to import a java class in a JSP

    Hi All,
    I have a java class file called myTest.class (i made after compilation of myTest.java). I have a JSP page that uses this java class file.
    These 2 files are in same folder called c:/test
    and iam importing this java class file into my jsp file and that too at the start of this jsp file:
    <%@page import="myTest" %>
    BUt iam getting an error ..............when iam running this JSP page:
    /opt/bea81sp2/user_projects/domains/wliDomain/./Managed2/.wlnotdelete/extract/Managed2_myTest_myTest/jsp_servlet/__test.java:20: '.' expected
    probably occurred due to an error in /test.jsp line 5:
    <%@page import="myTest" %>
    Please advise how to solve this problem
