CQL on complex java bean

Hello,
Is there a known issue of CQL not able to process a complex java bean structure? Simple java bean works just fine, but when I have bean nested in another bean, CQL can not process it.
Any pointer is greatly appreciated.
Thanks,
Brandon

Hi,
I am using the latest 11.1.1.3. Bellow is the error.

Complex Java Bean Model in WD

I've revised the question.. to make it more simple.
I have 2 wrapper classes, the first wrapper HAS the second wrapper as an object.
When importing the Java Bean Model in WebDynpro, it seems okay - did the context binding, etc. -- until I did an "Apply Template" (as form) on the layout based on the CommandBean (which has the wrapper class).
Now, the fields are not active fields.. I can't change the cardinality -- and I have played around with the relations of the model classes with each other.
Nothing seems to work
Please help.
Edited by: Jan Michael Jaudian on Oct 8, 2008 8:07 AM

problem solved.
forgot to completely bind inner nodes.
developers who need more info, do post here so I can help out in any way I can.

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.

Java bean implementation

i 'm developing a web service, in my service part , i got a complex type that i should return in a java bean.
I have a class in which i have defined my java bean, in an other class
I have extracted content from a database, i don't know how to process it to the java bean.
please help

From the class where you extracted content from the database, create a new bean and set the information through a set function.
example:
database.java
//get info from DB
InfoBean infoBean = new InfoBean();
infoBean.setName( <nameresultFromDB>);
infoBean.setCountry( <countryresultFromDB>);
etc.
if you got multiple beans to save, you should create a bean holder class that holds multiple beans for you.

CAN I DO DATA CACHING by JAVA BEAN persistence?

I need to keep Objects cached in the server side. so in order to make it persistence can i use JAVA BEANS.
I am not interested to do for EJB.
I need a cache component build in the server side .
how can i do it in JAVA / J2EE platform?

Your cache doesn't necessarily need to be persistant unless you're doing something like calculating the size or keeping it between server restarts.
A simple cache is very easy to do but can get quite complex very quickly. Search for Caching on javaworld.com there's a pretty good article on it there.
Also take a look for JCache on jcp.org, it's a request for a cacheing spec to be built into Java. Some interesting stuff there.
Basically all you need is a HashMap to hold, keys and objects.

Best way to automatically map Java bean hierarchy to JavaFx property bean hierarchy

We do not want JavaFx on the server side, so our DTO objects are plain Java beans.
On the client side, we want to use the comfort of JavaFx bindings. As we're using Java 7, POJO bindings aren't possible yet.
So we're looking for a way to automatically wrap the Java beans in JavaFx property beans.
Possible approaches I've been looking into:
- Code generation via JCodeModel
- JavaBeanPropertyBuilder
Ideally, we would want to have classes with structured JavaFx properties as a result, so that an ObjectProperty does not use the bean class, but always the respective JavaFx property bean class.
This is so we don't need too many low-level bindings, but can rely on deep select bindings.
This goes beyond the capabilities of JavaBeanPropertyBuilder as far as I understood it, so I'm left with fairly complex code generation using JCodeModel.
Does anyone have some experience to share? Am I missing an option?

Andipa wrote:

I'm sorry to reply without a good suggestion, but is there some type of POJO binding support in Java 8?
This is what I currently use for POJO binding, but it doesn't sound very close to what you're asking for. A lot of code still needs to be written by hand. Also, I've only used it with relatively flat models 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.
Sincerely,
Ted Ueda

          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.

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

Need Help-How Store the input parameter through java bean

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.
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.
Please review these code:
