When we can go for a java bean

Hi,
i would like to know when we need or when it will be useful the java bean in a client-server application deveoped by using forms 6i, could abybody help without a link .
Thanks
Bcj

Hi ,
In General words , using JavaBeans / PJC's (Pluggable Java Components) is used when you want to extend your Form Funcionality to Java , on other words , if you have a case on which that Forms API and packages can not help you then you can develop/use a Java Bean or PJC , take a look at this PDF (you don't like Links :) sorry ):

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

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.

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.

Why use a wait timer when you can "wait for front panel activity"?

Why does everyone:
1) Wire a stop button to the while loop conditional terminal and add a wait for 100 ms (or so) timer to the loop.
When they could:
2) Wire the stop button to the while loop conditional terminal AND to "Wait for front panel activity" VI as described in the VI's help file?
Thanks!
Adam

That's just a matter of habit. In previous LV versions, the wait for front panel activity was not available.
And of course, now you can use the Event structure, that offers better possibilities...Message Edité par chilly charly le 06-25-2006 04:11 AM

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).

Dynamic Java bean classes for XSD using JAVA (not any external batch or sh)

Hi,
How can we generate dynamic Java bean classes for XSD (dynamically support All XSD at runtime)?
Note: - Through java code via only needs to generate this process. (Not using any xjc.bat or xjc.sh from JAXB).
Thanks

Pretty sure you can't. Probably can do a lot of them with years of work.
And can probably can do a resonable subset suitable for the business at hand with only a moderate effort.
Note: - Through java code via only needs to generate this process. (Not using any xjc.bat or xjc.sh from JAXB).The Sun jdk, not jre, comes with the java compiler as part of it. You can create in memory class (I believe in memory) based on java code you create.
I believe BCEL alllows the same thing (in memory) but you start with byte codes.
You could just create a dynamic meta data solution as well, via maps and generic methods. Not as fast though.

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.

Seems to me that executeUpdate() would throw an SQLException, which in turn would get caught by your empty catch. The SQL keyword VALUES is misspelled. Put a 'se.printStackTrace()' in your catch to confirm this.
