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.

JAVA beans and JAVA related services require Oracle client to be installed?

Can you please advice whether an application server that make use of JAVA beans and JAVA related services require Oracle client to be installed? For an example if the solution build based on Java and JBOSS to be used as application server, do we still require oracle client to be installed and configure the tnsnames in order to communicate to database server?

Question about main difference between Java bean and Java class in JSP

Hi All,
I am new to Java Bean and wonder what is the main difference to use a Bean or an Object in the jsp. I have search on the forum and find some post also asking the question but still answer my doubt. Indeed, what is the real advantage of using bean in jsp.
Let me give an example to illustrate my question:
<code>
<%@ page errorPage="errorpage.jsp" %>
<%@ page import="ShoppingCart" %>

<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
<html>
<head><title>Shopping Cart</title></head>
<body bgcolor="#FFFFFF">
Your cart's ID is: <%=cart.getId()%>.
</body>
<html>
</code>
In the above code, I can also create a object of ShoppingCart by new operator then get the id at the following way.
<code>
<%
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
%>
</code>
Now my question is what is the difference between the two method? As in my mind, a normal class can also have it setter and getter methods for its properties. But someone may say that, there is a scope="session", which can be declared in an normal object. It may be a point but it can be easily solved but putting the object in session by "session.setAttribute("cart", cart)".
I have been searching on this issue on the internet for a long time and most of them just say someting like "persistance of state", "bean follow some conventions of naming", "bean must implement ser" and so on. All of above can be solved by other means, for example, a normal class can also follow the convention. I am really get confused with it, and really want to know what is the main point(s) of using the java bean.
Any help will be highly apprecaited. Thanks!!!

Hi All,
I am new to Java Bean and wonder what is the main
difference to use a Bean or an Object in the jsp. The first thing to realize is that JavaBeans are just Plain Old Java Objects (POJOs) that follow a specific set of semantics (get/set methods, etc...). So what is the difference between a Bean and an Object? Nothing.
<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
In the above code, I can also create a object of
ShoppingCart by new operator then get the id at the
following way.
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
...Sure you could. And if the Cart was in a package (it has to be) you also need to put an import statement in. Oh, and to make sure the object is accessable in the same scope, you have to put it into the PageContext scope. And to totally equal, you first check to see if that object already exists in scope. So to get the equivalant of this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart"/>Then your scriptlet looks like this:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = pageContext.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    pageContext.setAttribute("cart", cart);
%>So it is a lot more work.
As in my mind, a normal class can also
have it setter and getter methods for its properties.True ... See below.
But someone may say that, there is a scope="session",
which can be declared in an normal object.As long as the object is serializeable, yes.
It may be
a point but it can be easily solved but putting the
object in session by "session.setAttribute("cart",
cart)".Possible, but if the object isn't serializable it can be unsafe. As the point I mentioned above, the useBean tag allows you to check if the bean exists already, and use that, or make a new one if it does not yet exist in one line. A lot easier than the code you need to use otherwise.
I have been searching on this issue on the internet
for a long time and most of them just say someting
like "persistance of state", "bean follow some
conventions of naming", "bean must implement ser" and
so on. Right, that would go along the lines of the definition of what a JavaBean is.
All of above can be solved by other means, for
example, a normal class can also follow the
convention. And if it does - then it is a JavaBean! A JavaBean is any Object whose class definition would include all of the following:
1) A public, no-argument constructor
2) Implements Serializeable
3) Properties are revealed through public mutator methods (void return type, start with 'set' have a single Object parameter list) and public accessor methods (Object return type, void parameter list, begin with 'get').
4) Contain any necessary event handling methods. Depending on the purpose of the bean, you may include event handlers for when the properties change.
I am really get confused with it, and
really want to know what is the main point(s) of
using the java bean.JavaBeans are normal objects that follow these conventions. Because they do, then you can access them through simplified means. For example, One way of having an object in session that contains data I want to print our might be:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    session.setAttribute("cart", cart);
%>Then later where I want to print a total:
<% out.print(cart.getTotal() %>Or, if the cart is a JavaBean I could do this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session"/>
Then later on:
<jsp:getProperty name="cart" property="total"/>
Or perhaps I want to set some properties on the object that I get off of the URL's parameter group. I could do this:
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    cart.setCreditCard(request.getParameter("creditCard"));
    cart.setFirstName(request.getParameter("firstName"));
    cart.setLastName(request.getParameter("lastName"));
    cart.setBillingAddress1(request.getParameter("billingAddress1"));
    cart.setBillingAddress2(request.getParameter("billingAddress2"));
    cart.setZipCode(request.getParameter("zipCode"));
    cart.setRegion(request.getParameter("region"));
    cart.setCountry(request.getParameter("country"));
    pageContext.setAttribute("cart", cart);
    session.setAttribute("cart", cart);
}Or you could use:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session">
<jsp:setProperty name="cart" property="*"/>
</jsp:useBean>The second seems easier to me.
It also allows you to use your objects in more varied cases - for example, JSTL (the standard tag libraries) and EL (expression language) only work with JavaBeans (objects that follow the JavaBeans conventions) because they expect objects to have the no-arg constuctor, and properties accessed/changed via getXXX and setXXX methods.

Xi JDBC Adapter - Query SQL Statement & Update SQL Statement

Hi!
I configure the JDBC adapter sender (XI) to take data from Oracle database.
I set the Query and Update SQL Statement in the Processing parameters of the communication channel in this way:
Query SQL Statement :
SELECT * FROM XI_TABLE WHERE STATUS = 'WAIT' ORDER BY ROW_NUM
Update SQL Statement :
UPDATE XI_TABLE SET STATUS = 'DONE', DATE = SYSDATE WHERE STATUS = 'WAIT'
My question is :
If a new record with the field STATUS = 'WAIT' is added to the table (xi_table) during the time between the execution of the query statement and the start of the update statement, what will happen to that record during the update?
There is a way to avoid the update of that record? or to pass to the update statement only the record selected in the query statement?
Please, may you give me some example?
Thanks,
Francesco

hi,
did you check "Isolation Level for Transaction"
for the sender jdbc adapter?

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() ;

        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") ;

                        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>

Query SQL Statement & Update SQL Statement

Hi!
I configure the JDBC adapter sender (XI) to take data from MSSQL database.
I have to run select like this:
SELECT
tblMilestone.Site,
tblMilestone.Revision,
tblMilestone.MilestoneNameID,
tblMilestone.ApprovedDate,
tblMilestoneName.MilestoneName
FROM
tblMilestoneName
INNER JOIN tblMilestone ON tblMilestoneName.MilestoneNameID = tblMilestone.MilestoneNameID
WHERE tblMilestone.StatusCode = 1;
My question is what "Update SQL Statement" I should use in communication channel definition? I only need to update tblMilestone or this two tables?
Maybe you give me some example.

Check this from SAP help...
Update SQL Statement
You have the following options:
● Enter a valid SQL statement that is to be applied to the database once the data (determined from the Query SQL Statement) has been successfully sent to the Integration Server/PCK.
It must be an INSERT, UPDATE, or DELETE statement.
● In place of the SQL statement, you can also enter <TEST>. Once the data determined from Query SQL Statement has been successfully sent, the data in the database remains unaltered.
This is recommended if the data has not only been read, but also changed by a stored procedure entered under Query SQL Statement.

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

Is there an equivalent statement in Java for this PL/SQL stmt?

Hi,
I want to know if there is an equivalent statement
in java for this PL/SQL statement:
IF strTok IN('COM-1','COM-2','COM-3') Then
/* Do Something */
End If;
I tried using : // This is giving me errors..
if (strTok.equals(("COM-1") || ("COM-2") || ("COM-3") ) )
/* Do Something */
The above Java code is giving me errors.
Any Help to reduce the number of steps for comparison
is appreciated.
thanks in adv

Something like
if (strTok.equals("COM-1") ||
strTok.equals("COM-2") ||
strTok.equals("COM-3") )Justin

Convert a logic from SQL statement to java

Hi.,
I m using jdeveloper 11.1.1.5
I had used one sql statement as gievn below
(SELECT max(decode(LENGTH(fy_year),4, fy_year + 1,6,SUBSTR(fy_year, 1, 4)+1||SUBSTR(SUBSTR(fy_year, 1, 4) + 2, 3, 2)))YEAR from fin_years)I need to use this logic in java
Could anyone pls help me

"wilhelm,"
I've seen some ridiculous questions in my life. This is one of them.
There are just so many things wrong here. So, so many.
SELECT statements get data from databases; they are not "logic."
Do you really expect us to parse your SQL and try to guess what it is supposed to do?
Do you really believe that when converting a Forms app to Java that you "convert" SQL statements to Java?
Do you really believe that going through your forms app and "converting" it to ADF is a sensible approach?

Using Java Bean in JSP to show database record

I have links in my Tomcat container that if someone clicks on a specific link it should go to a Record page (Show.jsp) with all the values associated with a record from a database.
For example if someone clicks on a specific link like this:
LinkExample
it would take you to a jsp with database info for someone named Jones and show you his info:
Lastname = Jones
Firstname = Mike
City = San Diego
I would like to do this using a Java helper class and bean so I dont have any database connection or Java code in my JSP.
I created Java class file that has Database connection that works with a Java bean. I just dont know how to get the Show.jsp to work with the Java Bean and Java helper class file.
Here is what I have for Show.jsp and this is the part I have been working on the longest but cant get it to work because it doesnt seem to work with the database:<jsp:useBean id="user" class="num.UserDB"/>
//do I call getUser(lastname) here and if so how?
<jsp:setProperty name="user" property="*"/>
Last Name: <jsp:getProperty name="user" property="lastname"/><BR>
First Name: <jsp:getProperty name="user" property="firstname"/><BR>
City: <jsp:getProperty name="user" property="city"/><BR>My Java Helper class that compiles and connects to database:
package num;
import java.io.*;
import java.sql.*;
import java.util.*;
import num.User;
public class UserDB
public User getUser(String lastname)
User user = new User();
        try
     Class.forName...//database connection stuff here
    ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
     if(results.next() == true)
     results.next();
     user.setLastname(results.getString("lastname"));
     user.setFirstname(results.getString("firstname"));
        user.setFirstname(results.getString("city"));
     catch(Exception e)
               System.out.println("Exception...");
   return user;
}My Java Bean that compiles here:
package num;
public class User
private String firstname;
private String lastname;
private String city;
public User()
     //no arg constructor
public User(String firstname, String lastname, String city)
       this.lastname = lastname;
          this.firstname = firstname;

public String getLastname()
          return lastname;
public void setLastname(String lastname)
     this.lastname = lastname;
//more bean methods for all fields here

Sorry if I wasnt specific enough. I have a link that passes a value (field that is passed is called lastname) to a JSP where I want to show record info for that value that is passed.
My question is how do I show the database record info on Show.jsp for the lastname field value of Jones where I want to use a Java Bean and Database helper class in Show.jsp
Here is the message I get when I hit the link (LinkExample) and it goes to Show.jsp:

Java Beans in 11g !

Hi everyone,
We are using 11gr2 Forms/Reports 64-bit on Windows Server 2008 64-bit.
Now we want to use JAVA BEANS in our application.
Suggest me link and steps for installing/using JAVA BEANS compatible for 11gr2 Forms/Reports.
Kindly tell me benefits of using JAVA BEANS in our applications.
Thanks vth Regards.

Advantage of java beans is you can enhance the behavior of forms. Forms is as you know applet based running on the client. (There is a different technology associated with inserting your own java code into the loop on the application server, should you want to do that.) So with beans in theory you can get more code to run on the client and do things like read and write files on the client, communicate with devices on the client, etc.
Regarding doing that I think the executive summary is mostly look up Fbean in forms builder help.
How I came to that tentative conclusion (I haven't gotten mybean to work yet! What do I know?) follows.
Home of much forms info:
http://www.oracle.com/technetwork/developer-tools/forms/overview/index.html
Java beans are java obviously one has to acquire a certain level of expertise in java to deal with them but more importantly how to understand how to communicate between forms and the bean? It's hard for formists, living their lives at the outside of forms, who come up with an idea of something exceptional they want to do in forms, to translate that into the bean world. Then you have to think like a form and that's unknown territory.
One problem is terminology: what is a PJC and what is a bean? Is a bean a PJC? I have yet to definitely figure that out. The paper below says: "A javabean is a pjc which is of an unspecialized type". However after that was written seems like in many cases when people are referring to "pjc"'s they are thinking the pjc is a specialized type.
"Oracle9i Forms provides two mechanisms for extending the client with Java. The
Pluggable Java Component (PJC) mechanism, which was introduced with Forms
6i, and the newer Oracle9i Forms specific, enhanced JavaBean support
mechanism." (paper 2 below).
I was reading this document from 2000 which is interesting:
Paper 1:
http://www.oracle.com/technetwork/developer-tools/forms/documentation/269054-130573.pdf
It's talking about handlers and views and it's quickly getting over my head as I don't know enough forms internals to make much of this. For example I would like to write a bean that can print a small form. I have a proof of concept in java (6) that can print text to the default printer. So next step, create a bean that can get the data out of the form. From my formist perspective here I am in a bean how do I access some fields in a record in a block in forms? It's tough going. What does that mean in this handler/view world? Or do I have to be in the form and think of sending data to the bean and telling it to print it?
Paper 2:
http://www.oracle.com/technetwork/developer-tools/forms/documentation/269054-130573.pdf
Starts out with more on the handler/view thing. Unfortunately I am totally mvc or handler-view impaired. It escapes me totally.
"The Handler class is responsible for both maintaining the current value of any data and controlling the visual representation of the data."....vs.... "The View class is singularly responsible for presenting the data to the user in some
manner and handling user input. The View class may allow the data to be changed
by the user.". What? I am lost I have no idea what the handler does and what the view does. How about a discussion that is strictly goal oriented? If you want to do this, you have to talk to the (Handler| View)? Don't leave it to me to understand the handler/view thing and then figure it out from that. (This mvc thing is precisely what repels me about jdeveloper. You can't embrace jdev if you haven't drunk the mvc koolaid.)
Further on in the paper they bring up fbean:
"So in Oracle9i Forms a new simpler mechanism was introduced to allow you to integrate JavaBeans and Java
Applets as custom components without writing any Java Code at all. This is all handled using a PL/SQL package in Forms called FBean.
"FBean provides a full PL/SQL API to allow interaction with any public methods,
properties and events that a JavaBean or Applet exposes."
Now you're talking! This is more like it!:
"Executing Methods
Methods on the JavaBean are executed using one of the variety of
FBean.Invoke methods. Like the property getters and setters there are various
versions of this method which handle calling methods on the JavaBean that return
different datatypes (or return void):
• FBean.Invoke_Char()
• FBean.Invoke_Bool()
• FBean.Invoke_Num()
• FBean.Invoke()
Ok now that we know about the fbean thing we can find fbean in the forms builder help system. Looking good. I am pretty sure that somewhere in there you have to get your bean in a jar file and sign it (not a trivial proposition) and
change the forms server configuration to include your jar file. I also think that the bean has to import frmall.jar and some of the packages regarding that view stuff. A tutorial about fbean and all these details from start to finish would be super!
So you can talk to another applet? Really? Can this still be done considering all the security concerns in current browsers?

Java Bean access in a JSP Tag handler class

Hello Everybody,
I am trying to access my java bean(ErrorBean.java) in th doEndTag() method of the tag handler class(MyTagHandler.java) and iam getting an "CLASSCAST EXCEPTION"
I am doing it like this in the tag handler class.
MyBeans.ErrorBean errorBean = (MyBeans.ErrorBean)pageContext.getSession().getAttribute("ErrorBean");
Where MyBeans is the package in which my Error Bean is and iam placing the ErrorBean object in the session object before it comes to the jsp page where i have the jsp Custom tag:
<%@ taglib uri="/WEB-INF/taglib.tld" prefix="errors" %>
<errors:message/>
<%@ include file="footer.jsp"%>
I was of the opinion that i was casting it right...can anyone help me to find ...where iam doing it wrong...its really URGENT ..PLEASE

Friend that did not work either ...
u know what...the ErrorTagHandler class is comiling fine with out errors but in the jsp page when the custom tag is hit..this error is showing up when i see the server log.
can you throw some light on this..
thanks..

Spooling Extracts from Multiple SQL statements in 1 File

Hi all,
I am trying to spool extract results of 3 separate SQL statements into one single file. I wrote a SQL block similar to the one below. However, the result of the statements overwrite each other: 3 overwrote 2 and overwrote 1. Any suggestion how to combined there extracted results in one file?
spool c:\test.txt
<SQL statement 1>
<SQL statement 2>
<SQL statement 3>
/spool OFF
Thanks in advance
Jason

Please paste you SQL file here. These is no way one should overwrite another.
