Compiling Java Bean Example FileUploadUtility

Dear Oracle Gurus,
Trying to compile the FileUploadUtility example I have some problems:
It seems that the following libs are missing.
import oracle.forms.*
import oracle.ewt.*
Do I need any additional libraries ?
Is there any documentation how to compile the sample ?
thank you for your help !

Hi
Yes I can find
$ORACLE_HOME/forms60/java/ewt and
$ORACLE_HOME/forms60/java/bali
* I am using JDeveloper 3.2.3
What do I have to do ?
Is there any path I have to set to this package so that the import works ?
* Where can I find the following package ?
import oracle.forms.ui.VBean;
import oracle.forms.ui.CustomEvent;
import oracle.forms.handler.IHandler;
import oracle.forms.properties.ID;

Ok, jsp pages to not contain java beans, java beans are separate classes which you access from a jsp.
Is this what you have done, i.e. created classes under classes/yourPackage ?
If so, you do not need to recompile the class when you move it, you can move the pre-compiled class file.
In terms of your error, I have no idea, but it looks interesting!!
The most likely cause is a difference in the JDK versions you are running on the different machines. If the JDK on windows 2000 is older, you may need to upgrade it.

Pluggable Java Beans examples using Native IE mode

Hello
I would like to know if anybody has tested JPC using IE=NATIVE
setting to avoid using JInitiator
I have tried and done the following
I downloaded a JPC from http://forms.pjc.bean.over-blog.com/categorie-453384.html to try add File chooser functionality
I tried it useing Jinitiator and it works perfectly.
i then added the jar file to ARCHIVE_IE
archive_ie=f90all.cab,GetImageFileName.jar
The java console gave a message indicating that the JAR has been skipped.
I figured that i need to convert the jar file into a CAB file
I Used cabarc.exe to create MS archive cabinets
1- I extracted the GetImageFileName.jar file to an oracle directory
2- Archived again to MS format
cabarc -r -p n GetImageFileName.cab oracle\*.*
3- I included the cab file in the formsweb.cfg as follows
archive_ie=f90all.cab,GetImageFileName.cab
4- I ran the form, no error was generated, but at the same time the
function was not executed (no dialog poped up).
If you are wondering why i am not using webutil, it is because the user
does not want to use Jinit. Webutil does not work without Jinit.
thanks

While trying to work with PJC on Forms REL 2, i noticed that the default FORMWEB.CFG does not have all setting related to Native IE
Can anybody confirm if NATIVE IE is no more support in REL 2

Java server page compiler can not find a class defined in a java bean file

I have a jsp file using java bean. The java bean class file is uploaded into the server and also the directory to this java bean .class file is included in the Unix environment CLASSPATH. This .jsp file is registered and should be compiled and excecuted automatically.
WHen I try to invoke this .jsp file, the jsp compiler error, saying the class defined by java bean can not be found. I already include this path in teh CLASSPATH, I thought the jsp compiler will go to the right place according to CLASSPATH to find the referenced class.
Can anyone tell me what I have done wrong or what should I do in order to allow jsp compiler to find the class refrenced by .jsp file and defined by java bean file?
Thank you so much

hello friends,
i am also facing the same problem of not finding bean class files for both jsp and servlet though it is placed in same package. the problem of not finding bean class file for jsp is experienced in Tomcat server only whereas in Blazix, there is no such error and the file is compiled and runs successfully.
i have checked Tomcat properly. there is no error in its configuration also servlets without the use of bean files run successfully. so please can anybody guide me about what is the problem and how to solve it. plz its urgent .

First use of jsp and java bean and "Unable to compile class for JSP" error

Hi,
I am trying to create my first jsp + java bean and I get a basic error (but I have no clue what it depends on exactly). Tomcat seems to cannot find my class file in the path. Maybe it is because I did not create a web.xml file. Did I forgot to put a line in my jsp file to import my bean?
Thank you very much for your help.
Here is my error:
An error occurred at line: 2 in the jsp file: /login.jsp
Generated servlet error:

CMBConnect test = null;
I only have this in my directory:
test/login.jsp
test/WEB-INF/classes/CMBConnect.java
test/WEB-INF/classes/CMBConnect.class
Do I need to declare another directory in classes to put my class file in it and package my bean differently?
Here is my login.jsp:
<%@ page errorPage="error.jsp" %>
<jsp:useBean id="test" type="CMBConnect" scope="session" />

and here is my CMBConnect.java:

import java.sql.SQLException;
public class CMBConnect
public CMBConnect () { }
public String openConnection(String id, String password) {

try {

if(con.isClosed())

else

          You realy can do it like Xiang says, but the better way is to use packages. That's
          the way BEA is designed for. If you use packages you can but your bean classes
          in every subfolder beneath Classes. Here for example we have the subfolders test
          and beans:
          You have to declare the package on top of your Bean Source Code:
          package test.beans;
          In your JSP you don't need the import code of Xiang. You only have to refer the
          path of your bean class:
          <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
          There are some other AppServers that only can deploy Java Beans in packages. So
          if you use packages you are always on the right side.

Sir
Still my jsp files can't find java beans.
I set classpath properly .
my document directory = c:/raju
i put my jsp file = c:/raju/jsp/<jsp files>
and servlet files = c:/raju/servlet/<servlet class files>
actually jsp files and servlets were working successfully,
if i add my java beans inside my jsp file the it shows error.
inside my jsp file
<%@ page import ="something.myclass" %>

Using Java Bean in JSP to show database record

I have links in my Tomcat container that if someone clicks on a specific link it should go to a Record page (Show.jsp) with all the values associated with a record from a database.
For example if someone clicks on a specific link like this:
LinkExample
it would take you to a jsp with database info for someone named Jones and show you his info:
Lastname = Jones
Firstname = Mike
City = San Diego
I would like to do this using a Java helper class and bean so I dont have any database connection or Java code in my JSP.
I created Java class file that has Database connection that works with a Java bean. I just dont know how to get the Show.jsp to work with the Java Bean and Java helper class file.
Here is what I have for Show.jsp and this is the part I have been working on the longest but cant get it to work because it doesnt seem to work with the database:<jsp:useBean id="user" class="num.UserDB"/>
//do I call getUser(lastname) here and if so how?
<jsp:setProperty name="user" property="*"/>
Last Name: <jsp:getProperty name="user" property="lastname"/><BR>
First Name: <jsp:getProperty name="user" property="firstname"/><BR>
City: <jsp:getProperty name="user" property="city"/><BR>My Java Helper class that compiles and connects to database:
package num;
import java.io.*;
import java.sql.*;
import java.util.*;
import num.User;
public class UserDB
public User getUser(String lastname)
User user = new User();
        try
     Class.forName...//database connection stuff here
    ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
     if(results.next() == true)
     results.next();
     user.setLastname(results.getString("lastname"));
     user.setFirstname(results.getString("firstname"));
        user.setFirstname(results.getString("city"));
     catch(Exception e)
               System.out.println("Exception...");
   return user;
}My Java Bean that compiles here:
package num;
public class User
private String firstname;
private String lastname;
private String city;
public User()
     //no arg constructor
public User(String firstname, String lastname, String city)
       this.lastname = lastname;
          this.firstname = firstname;
          this.city = city;
public String getLastname()
          return lastname;
public void setLastname(String lastname)
     this.lastname = lastname;
//more bean methods for all fields here

Sorry if I wasnt specific enough. I have a link that passes a value (field that is passed is called lastname) to a JSP where I want to show record info for that value that is passed.
My question is how do I show the database record info on Show.jsp for the lastname field value of Jones where I want to use a Java Bean and Database helper class in Show.jsp
Here is the message I get when I hit the link (LinkExample) and it goes to Show.jsp:
org.apache.jasper.JasperException: Cannot find any information on property 'lastname' in a bean of type 'num.UserDB'
.....My UserDB class:
public class UserDB
public User getUser(String lastname)
User user = new User();
        try
     Class.forName("org.gjt.mm.mysql.Driver");
    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/dbconnone?user=smitherson&password=abcdefg");
    Statement stmt = conn.createStatement();
    ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
     if(results.next() == true)
     results.next();
     user.setLastname(results.getString("lastname"));
     user.setFirstname(results.getString("firstname"));
                     user.city(results.getString("city"));
     catch(Exception e)
         System.out.println("Exception..." + e);
   return user;
}Bean class:
package num;
public class User
private String firstname;
private String lastname;
private String city;
public User()
     //no arg constructor
public User(String firstname, String lastname, Sting city)
      this.firstname = firstname;
       this.lastname = lastname;
this.city = city;
public String getFirstname()
          return firstname;
public void setFirstname(String firstname)
     this.firstname = firstname;
public String getLastname()
          return lastname;
public void setLastname(String lastname)
     this.lastname = lastname;
public String getCity()
          return city;
public void setCity(String city)
     this.city = city;

Stepping into Java Beans from JSP

I am trying to figure out how to step into the Java Source code for my beans that are used in my JSP pages. I need to be able to debug them by stepping into them, using break points, etc.
I have Nitro installed and a sample JSP page with the import to my test Java Bean class. What I did was create two projects in my work space. One as a Web project application and one as a Java project. I referenced and opened both projects. Everything compiles fine and the syntax is correct.
The problem is I can not make the link for importing the class.
I get this error: Class com.BrianTest.MyBean not found in import com.BrianTest.MyBean
Anyone got a clue or a good example? I did try and add the class path and I tried to put it in a Jar file and attach the source to the Jar, but same problem.
Thanks :?

Stepping into jsp:useBean is not possible, but you can step-into jsp getter & setter tag.
Since you are using java bean from a dependent project you need to configure your server with DevLoader.
And currently only Tomcat server can be configured with Sysdeo Devloader to handle this situation
Download Sysdeo DevLoader for Tomcat from http://www.sysdeo.com/eclipse/tomcatPlugin.html
NOTE: If the project is self sufficient and not dependent on other projects/locations for classess/libraries then NitroX picks up all the libraries & classes present within default WEB-INF/lib & WEB-INF/classes respectively. And in this case you need not modify server configuration.
Sysdeo DevLoader is to allow your web project to use libraries/classes from dependent projects. All you need to do is extract DevLoader.zip present within tomcatPluginV3.zip inside your Tomcat/server/classes folder.
For more information about DevLoader please refer to http://www.sysdeo.com/eclipse/readmeDevLoader.html
This will solve your problem and you should be able to run/debug your application. And most important make sure you have the correct NitroX build that supports Sysdeo DevLoader, refer http://www.m7.com/whatsnew.htm document against your build id (Help > About NitroX > NitroX Icon)

Approach of Java Bean Model: What is the best way?

Hi Experts,
In our project, we are trying to connect Oracle Database and display the tables and information in it on Web Dynpro View.
For this I'm following 4 step procedure broadly:
1. Java DC: a) Create Class files --> one for connecting Database (JDBC Connectivity) ; other only having Input and Output variables with corresponding getter & setter methods ;and one more class file having all methods. I make Jar file out of this class files and store that within that DC project under _comp folder.
2. Ext Lib DC: a) Copy the created Jar file in Library and make 2 public parts (one PP for compile time and other PP for assembly time).
3. SAP J2EE DC: a) Create DC of type Library and above create PPs is added to this library.
4. Web Dynpro DC: a) Add SAP J2EE DC of Library Type in my Used DCs. b) This will make the JAR file created in Java DC to be available in options of " Jars from Pubilc Part" and use all these class files as Models. And Using them we access the Oracle DB and get access to data.
This proved to long exercise. I want to know if there is any other approach available other than this. I'm aware EJB Models approach, but this will be hit on my performance, so want to avoid this. Yet if any shorter approach is available.
My Idea behind this long approach is from the SDN provided example on Java bean where in Web Dynpro Project uses a local jar file created from Java project which wraps a EJB Module project and Enterprise Application project. So in DC perspective if we have to include jar file we have to make it public part.
<a href="/people/valery.silaev/blog/2005/09/14/a-bit-of-impractical-scripting-for-web-dynpro from Valery : A bit of (impractical) scripting for Web Dynpro</a> was in great help for making jar file exposed as Public part.
I want opinions and suggestion on this regard and best available approaches.
Thanks in advance

D.V.,
Here is an option to trun steps 1-4 into 1-2
As far as you are using your Java classes only from WD DC-s, then:
1. Put all your Java source in WD DC, create single public part for compilation. Bonus: you may create JavaBean model right here and add it to public part as well.
2. In other WD DC-s refer public part created above and add run-time reference (via Project -> Properties) to corresponding DC. Now you can use both Java classes and JavaBean model.

I've run many jsp files without problem, but when I use java Beans it doesn't work.
Thank you
P.D. The Classpath already contains the Java Bean file.

Hola Daniel,
Make this simple thing, import the class in your jsp, for example, in your case this should be:
<%@ page import="UserData" %>
The jasper compiler assumes that any unqualified class is part of the package jsps. I think this is to allow class definitions in the jsps. So if you indicate that the class is not packaged in jsps it will be found.

Hi,
Weblogic 6.0 (sp 6.1) can be installed in windows '98. But with slight changes. We need to convert all/required *.cmd files into *.bat files.
Let us take an example for startweblogic.cmd file. Convert the cmd extension into bat extension by saving. Then click on the batch file. If it gives any error, then right click on the top of startweblogic.bat. Select properties and select memory option.Change Initial environment to 1024.
It will work fine. I came to this forum for my problem. I suppose your problem is solved now.

Where to save the java bean in Tomcat?

hi,
im using a bean in a jsp. my coding of jsp is:
<html>
<head>
<title> JSP BEAN EXAMPLE </title>
</head>
<body>
<%@ page language="java" import="Counter" %>
<jsp:useBean id="counter" scope="session" class="Counter" />
<jsp:setProperty name="counter" property="count" param="count" />
<% out.println("Count from scriplet code:" + counter.getCounter() + "<br>"); %>
Count from jsp:getProperty:
<jsp:getProperty name="counter" property="count"/>
<br>
</body>
</html>
the bean is:
public class Counter
int count=0;
public Counter()
public int getCounter()
count++;
return this.count;
public void setCounter(int c)
this.count=count;
please tell me the correct location where i should save my bean file?
my jsp is saved at :Tomcat 4.1\webapps\ROOT
im getting an error such as

setCount() and getCount()
ur jsp code is here
<html>
<head>
<title> JSP BEAN EXAMPLE </title>
</head>
<body>
<%@ page language="java" import="SampleLib.Counter" %>
<jsp:useBean id="counter"class="SampleLib.Counter" />
<jsp:setProperty name="counter" property="count" param="count"/>
<% out.println("Count from scriplet code:" + counter.getCount() + "<br>"); %>
Count from jsp:getProperty:
<jsp:getProperty name="counter" property="count"/>
<br>
</body>
</html>
ur bean is herepackage SampleLib; // i have added package statement here
public class Counter
int count=0;
public Counter()
public int getCount()
