Representing java beans in uml

Hi
Can anyone tell me where i can find examples of how to model javabeans (not EJB) in UML?
Are there any particular methods of uml design that i should use such as "activity diagrams" for the system, or just "class diagrams" for the actual code?
I'm especially looking for design examples of a bound property bean, as i'm not quite sure how to represent them in a class diagram ?
Any help would be most appreciated,
Thanks!!!

as far as I'm concerned, I'm happy with a custom stereotype for beans, and maybe a custom stereotyped association between the bean and the page it backs...
now maybe there exist more complicated formalisms, the question is : are there useful for your purpose ?

How to represent java generics in UML

Hello,
Can anyone tell me how to represent java generics in UML? Say I have ClassA<ClassB>. How do I represent this in UML?
Thanks in advance,
Julien Martin.

More formally you can use parameterized types.
: T:Classifier :
+---------:..............:
| ClassA |
<<bind>> <T -> ClassB>
| ClassA<ClassB> |
Which may be useful if you have different instantiations of ClassA<T> with different values of T.

I can not drag java class onto uml class diagram - why??

Hi
1. I created a new java web project
2. I created a new uml project.
3. I created new classes in the java web project.
4. I created a new "class diagram" in the uml project.
PROBLEM:
1. When I drag one of the classes onto the class diagram screen, nothing happens. That is, when I perform the "drop"...nothing happens.
(NOTE: when I drag a "package" to the class diagram, a box representing the java package appears... I just cant get this to work for a class(s) )
QUESTION:
Should I be able to drag a class (or classes) from my web project src folder onto the UML project's class diagram and have UML representations of the classes appear?

Hi Shay
Unfortunately, I cannot view the suggested youtube stuff at work. (I'll try to view it when I get home)
But, in the meantime, I did kind of get things working...
After creating the java project and uml project (and initial class diagram), I had to
1. drag the java packages (containing the classes I wanted diagrammed) onto the root node of the UML project (i.e., located on the left side "navigation" bar). Afterward, the package appeared under the UML project....Then,
2. One by one I had to drag the individual java classes from the java project onto the root node of the UML project (i.e,. the classes then appeared under their respective packages under the UML project) . Then,
3. Then, finally, I could drag the java classes (listed under their respective packages under the UML project) onto the class diagram panel, where the rendered properly.
I dont know if this is supposed to be the way to "reverse engineer" java classes to be part of a UML class diagram... But, it was the only way I found that worked... thus far, anyway.
Thanks again for reading my post and answering so promptly.... That was much appreciated!

Help required in building up the Java Bean for an XML data

Hi ,
I want to build a Java bean which will actually represent an xml data . The class will be named as User and it will typically represent the data in the follwing xml:
<user>
<cwsId>barbete</cwsId>
<firstName>William</firstName>
<lastName>Barber</lastName>
<status>true</status>
<role>
<roleCode>1000000177</roleCode>
<roleName>Customer Administrator</roleName>
</role>
<language>en</language>
<country>US</country>
<preferences>
<equipmentGroup>2717</equipmentGroup>
<dateFormat>MON-dd-yyyy</dateFormat>
<timeFormat>HH:MI AM</timeFormat>
<timeZone>-12:00</timeZone>
<daylightSavings>Y</daylightSavings>
<location>NC</location>
<recordsPerPage>10</recordsPerPage>
<historyPeriod>3</historyPeriod>
<distanceUnit>MILE</distanceUnit>
<fuelUnit>G</fuelUnit>
<unitIdDisplay>E</unitIdDisplay>
<smuUpdate>W</smuUpdate>
<countries>
<country>
<countryCode>GB</countryCode>
<countryName>UNITED KINGDOM</countryName>
</country>
<country>
<countryCode>US</countryCode>
<countryName>UNITED STATES</countryName>
</country></countries>
</preferences>
</user>
Now for single child nodes like cwsId of the main user node i have kept properties like
private String cwsId;
But i am not sure as to how to represent the nodes which contain subnodes like "preferences"node. Any ideas?What is the standard practice?

One thing you could do is create an object model first, which will contain all the data for your user.
then all you need in the bean is a Hashtable with the name of the user as a key, and the user-object (which is actually the complete object model) as a value.
with the XML stated by you, you would get an object model something like this:
Class User
    String cwsid;
    String firstName;
    ArrayList<Role> roles = new ArrayList<Role>(); //I'm assuming a user can have more then one role.
    ArrayList<Country> countries = new ArrayList<Country>();
class Role {
    String code;
    String name;
class Country {
    String code;
    String name;
}And so on for all the varioous elemets of your XML.

Best approach for building dialogs based on Java Beans

I have a large amount of Java Beans with several properties each. These represent all the "data" in our system. We will now build a new GUI for the system and I intend to reuse the beans as far as possible. My idea is to automatically generate the configuration dialogs for each bean using the java.beans package.
What is the best approach for achieving this? Should I use PropertyEditors or should I make my own dialog-generator using the Introspetor class or are there any other suitable solutions?
All suggestions and tips are very welcome.
Thanks!
Erik

Definitely, it is better for you to use JTable. Why not try it?

Getting Java Beans working with Developer Forms 6i

Hello everyone,
I have been trying to get Java Beans to work with the Developer Forms 6i. I keep getting diffrent errors depending on the bean I play with. I will detail the problems and the computer setup. I am sure this problem is a configuration one, I just dont seem to have enough experiance to determine the issue or the configuration problem.
Here are the problems I am encountering:
Problems 1:
--JDeveloper 10g
I cant see the VBean class. When I add this code, the VBean decleration comes up with an error.
import oracle.forms.ui.VBean;
public class MyNewClass extends VBean
public Class1()
This code shows the IMPORT statement with a wavy blue line under it and the word VBean after the extends also has on. I understand that this means that the JDeveloper cant find the class, I just cant seem to find the correct environment variable to set to point to this.
Second Problem:
--Forms 6i
I open forms, and create a new form. I then add a datablock and a canvas. I open the canvas and drop the BeanArea component on the canvas. I enter the fully pathed/qualified Bean in the Implementation Class and get one of three errors. Either a FRM-13008, a FRM-99999 with a 13009 or a 13010 error. I suspect that the 13008 error is because the bean I created does not have the correct decleration types or IView interface calls. My problem is that when I load any of the Oracle provided beans I get the 13009 or 13010 errors. I have looked here and in Metalinks for some kind of solution that I haven't already tryed, but to no avail.
Any advice on either of these problems would be appreciated. Please keep in mind that we cant upgrade to version 9 or 10 yet (silly aif force and their regulations), so those type of solutions arn't usable to me.
Here is the configuration information that I know about. If there is more information that can be provided or I need to provide more information, please let me know and I will get what I can.
Thanks,
Bill Hunsicker

Ok, I added the f60all.jar to the project. This allowed me to create the file using the VBean. I created the JAR file and copied it to the forms60/java directory. I also copied the new .class files to the forms60/java/mil/af/rs/leads direcory.
I then edited my formsweb.cfg file and had to add the jinit_archive tag. I set it = f60all.jar, P3load.jar. I also added my P3load.jar file to the default archive tag.
When I open up Forms, drop the bean area component on the canvas, and set the Implementation Class, I still get an error (13008), and when I run the form in web, and click the button to invoke the bean I get no response from the bean.
here is the code to invoke the bean. in_filename is a text component on the canvas and contained in the CTRL block. The bean area is named BEAN (because the demo was that way).
:in_filename := get_custom_property('BEAN',1,'getFileName');
synchronize;
Not sure where to go from here, but thanks for the help so far.

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.

Ted Ueda

Problem with java beans and jsp on web logic 6.0 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.

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

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.
At run time servlet and server also show that loggging are saved in DB.
But when I open the table in Access. Its empty.
Ms-Access have two fields- User, Password both are text type.
