JAVA BEAN in forms9i

What are the steps for calling a java bean in forms9i?
I have to use find_item('java_bean_name)?
thanks,
Lionel

There is a bunch of information about it in the Java spotlight section on the Forms Upgrade Center at:

Displaying a JCombo Box in a Java bean with Forms9i

I am including a java bean in my 9i form which uses some swing component such as combo box. The problem is that when I show the popup menu of the combo box, I cannot see the list items available in the box. Is that of L&F problem or is it a Form rendering problem

Hi,
This sounds like a Swing issue that can be cause by the Forms ewt classes.

Running java bean from forms9i on win xp

hi all,
I have a form that uses java bean to write txt file on client computer. java bean connects to database and uses it's data to create txt file. everything runs fine on client with win2000, but with windows xp (professional, sp2, ie6.0) there seems to be some problem with connecting to db (returned connection is null). my win xp firewall is turned off, security settings (including java and activeX) are low, forms version is 9.0.4.0.19. java code seems to be ok, i think it has something to do with forms/xp compatibility. has anyone had similar problem?
Thanks for any response,
Albert

Thanks for your response. First version of our program was running on webutil, but as it turned out it was lacking performance. New version, with our custom java bean is much faster.
As I wrote it works on Windows 2000. It also works on WinXP as a standalone application. Only when deployed to Oracle Forms with XP client it fails. Error occures during retreiving connection to db when calling DriverManager.getConnection method. No exception is thrown, retreived connection is null.
Thanks for any help

Use Java Bean or Java Importer

I have created my java class to validate a user against LDAP and now I would like to use that class in my own 9i login form. In order to pass the class variable values to the form is it better to create a java bean or use the Java Importer? Which is better for performance?

Mike,
Java Beans added to Forms are downloaded to teh client as part of the application startup. The jar files get permanently cached on teh client until they are renewed on the server. For your original request, the funtionality already exists in a Forms9i demo

What is the difference between java direct or java bean in JSP?

What is the difference if I use java code directly in JSP or use java bean in JSP?
Which class to use for receiving the passed parameter from html or java script? Any difference for java code and java bean in the way receiving the passed data?
How can I pass string from jsp to html or java script?

it's generally accepted as better design to separate presentation from logic. meaning, the java code in the jsp should be used to support displaying data, as oppsoed to implementing the application - like database access, etc.
when the logic is separated from the presentation, it allows you to reuse logic components within several jsp pages.
if you decide to change the presentation layer in the future (to support wap, for example) you don't need to rewrite your entire application, since the "guts" of the application is outside of the jsps.
it is also a good idea to separate your business logic from your data layer. adding a "buffer zone" between these layers helps in the same manner as in separating presentation from logic. if you're using flat files for storage now, upgrading to a database wouldn't require rewriting all your business logic, just the methods which write out the data to a file, for example.
once you feel comfortable with separating the various layers, check out the struts framework at http://jakarta.apache.org/
to answer your second question, to get parameters passed in from HTML forms, use ServletRequet's getParameter() method.
in tomcat:
<% String lastName = request.getParameter( "lastname" ); %>
to answer your third question: when displaying the HTML from withing a jsp, print out the string to a javascript variable or a hidden form element:
<% String firstName = "mike"; %>
<input type="hidden" name="firstname" value="<%= firstName %>">
<script language="javascript1.2">
var firstName = "<%= firstName %>";
</script>
this jsp results in the following html:
<input type="hidden" name="firstname" value="mike">
<script language="javascript1.2">
var firstName = "mike";
</script>

Java Bean Connectivity and Closing Connections (XI 3.0)

Hi guys,
We have existing Java Beans that we would like to use with Crystal Reports. Our current Java beans return a disconnected GridModel and explicitly close the connection immediately after so that they can be returned to the connection pool (Oracle).
Once we modified these beans to return ResultSets we found that closing the connection also closes all the associated ResultSets and Statements.
What is the best practice here?
Modify the Java bean to close the connection in the finally block?
Will Crystal clean up after itself?
I also see there is something called a CachedRowSet which is disconnected:
http://java.sun.com/j2se/1.5.0/docs/api/javax/sql/rowset/CachedRowSet.html
Is this supported by Crystal?
Thanks,
Kevin D Lee =)

Hello Kevin,
Enterprise XI 3.0 CRConfig.xml points to Java JRE 1.5 provided with the install, so you should be ok with the CachedRowSet.
It's used by other customers for disconnected operation.
Since you're going to Oracle, you'd likely encounter issues mapping Oracle fields to POJO property types.
Furthermore, POJO Factory libraries that were shipped with Crystal Reports XI Release 2 aren't shipped with Enterprise XI 3.0, so you'd not find that an out-of-the-box option.
Another alternative to CachedRowSet is to define callback method in your JavaBeans class that Crystal will call when it's done with the data source.
This has been implemented in XI 3.0 (track ADAPT00877915) - excerpt from the track note:
<JavaBeans>
    <CacheRowSetSize>100</CacheRowSetSize>
     <JavaBeansClassPath>c:\javabeans\</JavaBeansClassPath>
     <CallBackFunction>CrystalReportsLogoff</CallBackFunction>
</JavaBeans>
      Customer can configuration the <CallBackFunction/> to let CR know
      which function should be invoked when loging off.
Advantage of CachedRowSet is that you can immediately close it after you've read all the data, disadvantage would be the default implementation stores all data in memory.
Advantage of the callback method is that it would use the JavaBean you've supplied (and not load all data immediately in memory), but callback won't be called immediately, but only after the report is done with.
Sincerely,
Ted Ueda

Problem with java beans and jsp on web logic 6.0 sp1

          HI ,
          I am using weblogic6.0 sp1.

          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.

How to make view Java Bean as .ocx file.

Hi All,
I want to use a visual Java Bean in Visual basic. So that I can modify all the bean properties as modify properties in a ocx file.
I used ActiveX Com bridge downloaded from Sun's site. But the packager
makes a .tlb file .
This file can only be added as a reference in visual basic but not as a ActiveX control. Is there any way out to do that???
Thanks & regards.
Nimesh

The packager creates a registry file and a tlb file.
After registering this .reg file, java bean can be used as an ActiveX control.
From within Visal Basic, select the "Tools" menu and "Custom Controls" item and add the Bean control that was generated.

Urgent : java bean having bidirectional one to many relationship

Hi,
We have complex requirement in our application.
We need to copy java bean having bidirectional one to many relationship to another javabean having bidirectional one to many relationship..
E.g
Class Basket1 {
public String color;
pubic String type;
public List<Basket1> basketList = new ArrayList()
Class Basket2 {
public String color;
pubic String type;
public List<Basket2> basketList = new ArrayList()
We need to exact copy Basket1 to Basket2. We are in trouble to copy List of child because we do not have how many child Basket1 have of same type..
Can someone help us how we can implement such kind of complex object bidirectional one to many relationship??

I can't see anything bidirectional about these relationships. What I can see is a couple of BasketN classes that look identical so I don't know why they both exist, and they both contain lists of themselves as members, which suggests some kind of tree structure. Nothing bidirectional there. I can see tat these things can form circular object graphs but I don't see why you would want to do that.
We need to exact copy Basket1 to Basket2And I don't know what that means. Please explain.

How to read the current value of hyperlink java bean in multiple record,

I have used a java bean for a multi-record block item. On When-new form-instance I m using fbean package as follows
FBean.Register_Bean(hHyperlink,1,'oracle.forms.demos.beans.Hyperlink');
FBean.Invoke(hHyperlink,1,'setURL','Abc_Entry');
FBean.Invoke(hHyperlink,1,'setLabel','Abc Document');
FBean.Enable_Event(hHyperlink,1,'actionListener',true);
You can see that I am using the number 1 which is hardcoded,for which I will replace with a incremental loop and remove it. Now when I m using the When-Custom-Item-Event, I want to read the URL for the current instance.
I m using
vcEventData := Fbean.Invoke_Char('CONTROL.HYPERLINK',2,'getURL');
to get the second record value , where in I want to avoid the hardcoded 2 or 1
Thank you

Hello Sir,
I have a simple Issue but It is not resolve by me i.e input parameter
are not store in Ms-Access.
I store the input parameter through Standard Action <jsp:useBean>.
jsp:useBean call a property IssueData. this property exist in
SimpleBean which create a connection from DB and insert the data.

WDVisibility type paramter in Java Bean(Web Dynpro DC in CE 7.1)

Hi All,
I need to set a WDVisibility type paramter in a java bean and i am able to do so.It imports com.sap.tc.webdynpro.progmodel.api.WDVisibility class .
The problem is when i am creating a Java Bean model it is not allowing me to select the Java bean class it gives an error message" Invalid Class : No class files found for JavaBean : com/sap/tc/webdynpro/progmodel/api/WDVisibility".
The java Bean class exists in Web Dynpro DC>src folder.
Any Pointers?
Regards
Avinash

Hi Ondrej ,
Refer the above links to convert the component of the first dc as a public part.
Then declare the methods which are written in the component controller of the first DC in the interface controller with the same signature.( When method is called automatically component controller method is called)
In second dc in component controller properties tab add the reference of the first dc.
Then access the method in second dc as
wdthis.wdget<UsedComponent name>Interface.methodname();
Thanks & Regards,
Ardhendu

An error in jsp page useBean when i try to include the java bean package?

Hi Sir,
I am using import com.project.ShowData in java beans inorder to connect to the jsp.
The jsp code goes like this:-
<%@ page import="com.project.ShowData" %>
<jsp:useBean id="jspuser1" class="com.viman.ShowData" scope="session"/>
<jsp:setProperty name="jspuser1" property="*"/>
Here the error is showing as cannot resolve symbols in com.project.ShowData.But i have given the same in java beans like this:-
Package com.project;
//import of package goes here
public class ShowData
//code goes here
It seems that all are correct here.I have done few programs using this without any problem.But suddenly it is giving a problem like this.What is the problem here?It is quite Urgent.Thank u.
