Java Bean Problem

Hi,
          I have encountered a Java bean/JSP problem. I have developed a simple test
          case as follows:
          Paramtest.jsp:
          <html>
          <head>
          <title>Param Test</title>
          <body>
          <p>
          <form name="form1" method=post action="formtest.jsp">
          <input name="check1" type="checkbox">Check1
          <br>
          <input type="submit" value="OK" type="submit">
          </form>
          </body>
          </html>
          Formtest.jsp:
          <jsp:useBean id="cbtest" class="com.ebiffa.cbtest"
          scope="request" />
          <jsp:setProperty name="cbtest" property="*" />
          <html>
          <body>
          check1= <%= cbtest.getCheck1() %>
          </body>
          </html>
          cbtest.java:
          package com.ebiffa;
          public class cbtest {
          boolean check1;
          public void setcheck1 (boolean check1) {
          this.check1=check1;
          public boolean getCheck1() {
          return check1;
          When I run the program check1 always shows 'false' regardless of whether the
          checkbox is checked.
          I am running Weblogic 5.1.0 SP8
          The program works OK on Tomcat
          Any ideas ???
          Thanks in anticipation

Passing parameter from JS to Java Bean.

We are using bing map to display outages data.
Now requiement is
in our JS we have
var description;
description=description + "<br><br>" + "Click " + "<a href='javascript:openPopUp()'>"+"*here*"+"</a>" + " to view full list of incidents";
I am also getting cityname[i]
so here i need to pass cityname on click of here to one of my java bean function.
from where i am calling one method that takes city name as input and will return full list of incidents.

here is how i was able to do .. In my javascript I am preparing param set and setting it to an event and raising this event.
On my UI.. using a ServerListener.. I am binding this event to an bean method where I am able to access the param.
here is the javascript:
function myClientListener(event){
var element = event.getSource();
var param = {city:"new york", country:"US"};
AdfCustomEvent.queue(element, "jsServerListener", param, true);
event.cancel();
jspx:
<af:serverListener type="jsServerListener"
method="#{MyBean.serverEventHandler}"/>
bean method:
public void serverEventHandler(ClientEvent clientEvent) {
System.out.println(clientEvent.getParameters().get("city"));
System.out.println(clientEvent.getParameters().get("country"));
this may be helpful:

          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.

Problems with a java bean in Weblogic 5.1

Hello,
          I am having a problem deploying a java bean in Weblogic 5.1:
          I have been given a .class and a .jar file for a java bean (not an EJB). I
          placed the .class file into e:\temp\WEB-INF\classes and added the following
          line to my weblogic.properties file:
          weblogic.httpd.webApp.testApp=e:/temp/
          I have also updated the web.xml file in the WEB-INF directory as follows:
          <?xml version="1.0" encoding="UTF-8"?>
          <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web
          Application 1.2//EN"
          "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
          <web-app>
          <servlet>
          <servlet-name>EdIface</servlet-name>
          <jsp-file>test.jsp</jsp-file>
          </servlet>
          <servlet-mapping>
          <servlet-name>EdIface</servlet-name>
          <url-pattern>EdIface</url-pattern>
          </servlet-mapping>
          </web-app>
          When I try to access my http:\\server:port\testApp\test I get an "Error
          500 - internal server error".
          Has anyone had experice with deploying a java bean with jsut the .class and
          .jar file? Where should I put the .jar file?
          I appreciate any advice!

Implementing java beans in forms 10g [Problem]

Hi All,
I am trying to implement the java bean in the forms 10g
I performed the following steps, but no luck.. Could anybody please help me in this?
I have created a simple java class
package mypackage1;
public class MyClass
public String GetString(String a)
return a;
Make a jar myjar.jar out of it.
Copy this jar files in $ORACLE_HOME/forms/java directory
and set the archive.jini parameter in formsweb.cfg to
archive_jini=frmall_jinit.jar,Myjar.jar
Created a simple form having one button, one textbox
Set the implementation class property of text item to mypackage1.MyClass
on button pressed trigger, I wrote
set_custom_property('block2.text_item4',1,'GetString','Hello World');
Ideally, on button pressed, it should show the text "Hello World" in the etxt box. But on button pressed nothing is happening and in java console on error is appearing.
My java console output is
Loading http://asst104253:8889/forms/java/frmall_jinit.jar from JAR cache
Loading http://asst104253:8889/forms/java/Myjar.jar from JAR cache
proxyHost=null
proxyPort=0
connectMode=HTTP, native.
Forms Applet version is : 10.1.2.0
Could anyone please tell me what I am doing wrong?? And how do I achieve this functionality??
Please, any help appreciated !!

Hi there
The is plenty wrong with this code:
1. MyClass is not extending VBean
2. There is no public boolean setProperty(ID ID, Object args) method and no property IDs have been defined so set_custom_property('block2.text_item4',1,'GetString','Hello World'); will not execute anything
3. If you're hoping to return values back from the bean, you need to define a custom event and associated ID.
If you're just looking for some java code to return values in a similar manner as normal Oracle functions then you may want to consider using forms java stored procedures which are based on static java methods. Beans are really more for interaction type stuff with other applications.
But any way if you want to do it this way (i.e. using beans) then at very least you class should look something like (Note, I have not compiled is so there may be a few errors):

Keep your button as is and then to return the value back into forms place a WHEN-CUSTOM-ITEM-EVENT trigger on the bean area with something like this:
DECLARE
     BeanValListHd1 PARAMLIST;
     ParamType NUMBER;
     EvenName     Varchar2(20);
     CurrentValue Varchar2(2000);
BEGIN
     BeanValListHd1 := get_parameter_list(:SYSTEM.CUSTOM_ITEM_EVENT_PARAMETERS);
     IF :SYSTEM.Custom_Item_Event = 'returnEvent' THEN
          IF iD_NULL(BeanValListHd1) THEN
          MESSAGE('NO PARAMETER FOUND FOUND');
          ELSE
          GET_PARAMETER_ATTR(BeanValListHd1,'returnValue',ParamType,CurrentValue);
          MESSAGE('IN CUSTOM EVENT THE STRING RETURNED IS '|| CurrentValue);
          END IF;
     ELSE
          MESSAGE('no value');
     END IF;
END;
hope this helps
Q

Problems with the ActiveX bridge for Java beans when using third-party .jar

I encountered the following problem when using the ActiveX bridge for a java bean:
I am using JDK 1.4.2_09 and MS Visual Basic 6.0 (SP6). I wrote a java bean called ProcessViewer (my class ProcessViewer inherits from JComponent and implements the interfaces Serializable and AdjustmentListener) which I would like to use within a VB 6.0 application. I used the ActiveX bridge (packager.exe) to generate a DLL (ProcessViewer.dll) and registered it successfully. The java bean GUI-control works fine within my VB 6.0 application unless my java bean (ProcessViewer.jar) uses any third-party .jar files.
But when I tried to add a reference to some third-party class (com.sap.xxx.xxx....) I got some problems. I could solve the problem with packager.exe by setting the correct CLASSPATH. But at runtime my VB 6.0 application does not work. It crashes or it reports an error like this: "The control ... could not be loaded from axbridge.dll" (although I deployed my .jar file correctly to the directory C:\Programme\Java\j2re1.4.2_09\axbridge\bin and lib). Setting the CLASSPATH environment variable before calling my VB 6.0 application (exe) did not solve the problem.
How can I teach my VB 6.0 application (containing the Java bean ActiveX control) where to find the third-party .jar file? Copying the third-party .jar file to the JRE lib-folder or to the axbridge\lib folder did not solve the problem either.
I studied the documentation about the ActiveX bridge given at:
http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/index.html
but I am missing informations on how the third-party .jar files can be found during runtime of the ActiveX container (e. g. a VB 6.0 application).

}Thanks.

Dear Sir,
I removed the singleaquotes from preparedstatement.But Its not executed in this function.Like:
public void submitData()
try
System.out.println("Printed*************************************************************");
Class.forName("oracle.jdbc.driver.OracleDriver");
System.out.println("Loading....");
Connection con=DriverManager.getConnection("jdbc:oracle:thin:@VijayKumar-PC:1521:XE","SYSTEM","SYSTEM");
System.out.println("Connection created");
PreparedStatement st=con.prepareStatement("delete from simple where NAME=? and BNAME=? ");
String User=getUserName();
st.setString(1,User);
String Bname=getBookName();
st.setString(2,Bname);
int y= st.executeUpdate();
System.out.println(y);
System.out.println("Query Executed");
con.commit();
con.close();
System.out.println("Your Book are Submitted *****************");
catch(Exception e)
e.printStackTrace();
}Allthough Insert command is properly executed in another function of Java Bean.
Please review...
Thanks.

Problem KeyEvent Java Bean (Francois Degrelle)

Hello !
I have a problem with the KeyEvent Java Bean (keykressed.zip)
from the Forms - PJC and JavaBean store !
1.
I call a forms-dialog and use the KeyEvent Java Bean.
(Set_Custom_Property('BL.BEAN',1,'INIT','')
2.
I call a second forms-dialog and use the KeyEvent Java Bean too.
Set_Custom_Property('BL.BEAN',1,'INIT','')
3.
Now i go back to the first forms-dialog and this dialog hangs...
(No input over keyboard possible !)
Maybe you can help me ?
Many thanks in advance !
Thomas

Hello,
Re-load the JAR file from the article.
I still get an error in the Java console after closing the second dialog, but the key is correctly sent to the first form, so it seems to be OK.

I would run both sides in a debugger and see what code is getting invoked

Using Java Beans in Java Server Pages

Can we not use a method of Java Bean in a Java Server Page ?
I am trying to retrieve the user email from a java bean method "getUserEmail". I am instantiating the class, but when I try to use that in JSP tags, I am getting an error.
<jsp:useBean class = "formjavabean.application" id = "applicationId" scope = "session" />
<%@ page import="java.io.*, java.lang.*" %>
<%!
String user = applicationId.getUserEmail() ;
String f3 = "ftn03" ;
String f3not = "ftn03 file not uploaded";
...........I am failing in debugging that, can anyone help plz ?

Here is my whole code in parts:
First the head section:
<head>
<title> Fastran </title>
<jsp:useBean class = "formjavabean.application" id = "applicationId" scope = "session" />
</head>JSP part in the body section :
<%@ page import="java.lang.*, java.io.*" %>
<%!
private String f3 = "ftn03";
private String f3not = "ftn03 file not uploaded";
private String f7 = "ftn07";
private String f7not = "ftn07 file not uploaded";
private String f9 = "ftn09";
private String f9not = "ftn09 file not uploaded";
public String checkFile3()
    File ch3 = new File("C:\\JBoss\\jboss-4.0.5.GA\\bin\\Fastran\\ftn03") ;
    if (ch3.exists() == true)
        return f3 ;
    else
        return f3not ;
public String checkFile7()
    File ch7 = new File("C:\\JBoss\\jboss-4.0.5.GA\\bin\\Fastran\\ftn07") ;
    if (ch7.exists() == true)
        return f7 ;
    else
        return f7not ;
public String checkFile9()
    File ch9 = new File("C:\\JBoss\\jboss-4.0.5.GA\\bin\\Fastran\\ftn09") ;
    if (ch9.exists() == true)
        return f9 ;
    else
        return f9not ;
%>Java Script in the body section, using methods defined in the JSP part:
<script type="text/javascript">
        function validate_file ( )
                var file3 = "<%= checkFile3() %>" ;
                var file7 = "<%= checkFile7() %>" ;
                var file9 = "<%= checkFile9() %>" ;
                if ( file3 != "ftn03" || file7 != "ftn07" || file9 != "ftn09" )
                    alert("Please upload the required file") ;
                    return ("fastran.jsp") ;
                else
                    return ("processForm.jsp") ;
        function validate_upload ( )
                valid = true;
                if ( document.val_file.filefield.value == "")
                        alert("Please select a file for upload") ;
                        valid = false;
                return valid;
    </script>Finally the form and button part of the page, in the body section:
<form name = "val_file" method="post" action="upload.jsp" name="submit" enctype="multipart/form-data" onSubmit = "return validate_upload();">
Upload Files: <input type="file" name="filefield" >&nbsp&nbsp<input type="submit" name="submit" value="Upload"><br>
<font color = "Red"><h5>(ftn03,ftn07, and ftn09)</h5></font><br><br><br>
Files on the server :<br><br>
<font color = "Green"><h5>
<%= checkFile3() %><br>
<%= checkFile7() %><br>
<%= checkFile9() %><br>
</h5></font>
<br><br><br><br><br><br><br><br><br>
<input type=button onClick="location.href='logintest.jsp'" value='Home'> <input type=button onClick="location.href=validate_file()" value='Proceed' ><br>
</form>Now try this:
Change <%! to <%, or try using bean method as:
String userEmail = applicationId.getUserEmail() ;..........and that is my problem. I would really appreciate any help, thanks

Java.beans.Statement & java.sql.Statement

My old code from jdk1.3.1 throws the ambiguous class thingie-mo-bob. Why did they implement the new java.beans.Statement, and is there anyway to make it default to the old java.sql.Statement without having to go through all the old code and add import java.sql.Statement. I have like 200 jsp files 'n it will take a loooong time!
Pete

There r two ways to do this.
(i) One is Implement the java.sql.Statement
like
package java.beans;
public interface Statement implements
java.sql.Statement {
}What? Are you suggesting he edit the source code for java.beans.Statement and make it implement java.sql.Statement?? I would most certainly not suggest that solution- beside violating the licensing agreement, it has troubling consequences since you are basically redefining the structure of a class in a way that makes no functional sense- that is, there is no reason for java.beans.Statement to implement methods like getConnection() and the other signatures of java.sql.Statement.
I'm not sure if I'm reading your response correctly or not, but I would definitely not refactor java.beans.Statement just to get this problem solved with out editing files ... ... since java.sql.Statement is used so widely, perhaps they should have considered a different name for java.beans.Statement , although you hate to base a name off of what's going to cause the least problems, rather then what makes the most sense ... ... any way, I guess it doesn't matter now: the name has been selected .... I'd be interested to hear how you solved the problem.

What makes a Java Bean invaild for a model import?

I'm busy prototyping some functionality that will expose some MDM 5.5 data through a WebDynpro application. I'm having a problem creating a java bean that will sit in front of an EJB, in that the Bean importer will refuse to import a bean if a certain line of code in a method is visible. Here's the offending code from the method:
try {
     A2iResultSet rs = cat.GetRecordsByValue(ary, rsd, Schema.MyTable.NAME);
     setEventLocation(rs.GetValueAt(0, Schema.MyTable.EVENT_LOCATION).GetStringValue());
} catch (StringException e) {
     setEventLocation("failed to find record");
Note that I have a class instance variable called 'eventLocation', which has get/set methods defined for it, thereby satisfying the Javabean requirement.
The first two lines of the 'try' block are the problem. If I comment them out and assemble the DC, I can import the Bean into a model with no issues. If I uncomment them, I cannot import the bean - I get a message that says 'Invalid Jar - no beans to import'.
Can someone explain why this is happening? Does it have something to do with the StringException? As far as I can tell from the Java bean model import documentation, I think I'm doing everything correctly, but something must be amiss.
Suggestions?

Pablo,
Now I understand your question in comments to my blog better
You have to add "ejb20" classes to your WebDynpro project as well, and import model afterwards.
In WebDynpro DC expand path (<project> -> DC MetData -> DC Definition -> Used DC) and invoke "Add Used DC..." in contextual menu. In dialog select "<dev. config> -> SAP-J2EE -> ejb20 -> DC MetaData -> Public Parts -> default". Set dependencies Built-time (probably Design-time as well). Click OK. Try to import model. If fails, restart IDE and try to import again.
