Know Java classes & subclasses

I´m wirking with Forms & Report 10GR2.
I´m working with Forms & Report from year 1.997. Normallly I rotate between 8 or 9 diferents application. My applications now appear a little old fashioned. Looking for to resolve this I find a article from Grant Ronald, I think well know in this forum, He have resolved me some question that I post here. In this article Grant say this :
Extending the Forms UI
So how can you achieve the balance of giving your
Forms application the makeover to bring it into the 21st
century without having to embark on a massive program
of redevelopment or user retraining?
The answer lies in the architecture of Oracle Forms.
For a Forms application running through a browser, the
user interface is rendered as a Java applet. This Java applet
includes a number of Java classes responsible for
rendering each of the Forms’ UI components. The magic
lies in the fact that since each UI component is, in effect,
a Java class, it can be subclassed. This means you can
create your own component that does everything the
base component does, but with your own added code to alter
the functionality or look and feel.
Really a piece of gold, in this, he give you the key to can change the forms look & feel.
But, now come the questions, how I can do this? how I know what classes use forms for display a buttom for example, what I must do for subclasses it?
is there any example or documentation that can help me? if yes ¿where? Can any of the gurus give me some links to explore this?
Thanks & regards everybody.

Look at this.

It is not supported by Oracle, but is widely used. All support for its use will come from its web page.

How to call a PL/SQL procedure from a Java class?

Hi,
I am new to the E-BusinessSuite and I want to develop a Portal with Java Portlets which display and write data from some E-Business databases (e.g. Customer Relationship Management or Human Resource). These data have been defined in the TCA (Trading Community Architecture) data model. I can access this data with PL/SQL API's. The next problem is how to get the data in the Java class. So, how do you call a PL/SQL procedure from a Java program?
Can anyone let me know how to solve that problem?
Thanks in advance,
Chang Si Chou

Have a look at this example:
final ApplicationModule am = panelBinding.getApplicationModule();
try
     final CallableStatement stmt = ((DBTransaction)am.getTransaction()).
                                                                                     createCallableStatement("{? = call some_pck.some_function(?, ?)}", 10);
     stmt.registerOutParameter(1, OracleTypes.VARCHAR);
     stmt.setInt(2, ((oracle.jbo.domain.Number)key.getAttribute(0)).intValue());
     stmt.setString(3, "Test");
     stmt.execute();
     stmt.close();
     return stmt.getString(1);
catch (Exception ex)
     panelBinding.reportException(ex);
     return null;
}Hope This Helps

Get the relative path for java class

How to get Relative path for java class which is inside in web-inf directory in webapps

Hi gimbal2,
My Requirement is i need to run a java class from batch file,when i created batch file in that i need to mention the complete path of the java class,so instead of mentioning that i want to provide only java class name,thats why i asked that one..
can u help me regarding that....
Thanks in advanceI wonder how that would work then. Let's take a fictive example. You have a class com.mycompany.myapp.Foo. This would mean that the class is stored in some directory like this:
c:/webrootdir/myapp/WEB-INF/classes/com/mycompany/myapp/Foo.classTo be able to run such a class from the commandline using Java, you would have to invoke this command:
java -cp c:/webrootdir/myapp/WEB-INF/classes com.mycompany.myapp.FooHow would knowing the exact path to this class help you?

How to return Values from Oracle Object Type to Java Class Object

Hello,
i have created an Oracle Object Types in the Database. Then i created Java classes with "jpub" of these types. Here is an example of the type.
CREATE OR REPLACE TYPE person_type AS OBJECT
ID NUMBER,
vorname VARCHAR2(30),
nachname VARCHAR2(30),
geburtstag DATE,
CONSTRUCTOR FUNCTION person_type RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_id NUMBER) RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_vorname VARCHAR2,
p_nachname VARCHAR2,
p_geburtstag DATE) RETURN SELF AS RESULT,
MEMBER FUNCTION object_exists(p_id NUMBER) RETURN BOOLEAN,
MEMBER PROCEDURE load_object(p_id NUMBER),
MEMBER PROCEDURE save_object,
MEMBER PROCEDURE insert_object,
MEMBER PROCEDURE update_object,
MEMBER PROCEDURE delete_object
MEMBER PROCEDURE load_object(p_id NUMBER) IS
BEGIN
SELECT p.id, p.vorname, p.nachname, p.geburtstag
INTO SELF.ID, SELF.vorname, self.nachname, SELF.geburtstag
FROM person p
WHERE p.id = p_id;
END;
My problem is, that if i use the member function "load_object" from my java app it doesnt return the selected values to the java class and i dont know why. I use the java class like this:
PersonObjectType p = new PersonObjectType();
p.load_object(4);
There is a reocrd in the database with id = 4 and the function will execute successful. But if i try to use "p.getVorname()" i always get "NULL". Can someone tell me how to do that?
Thanks a lot.

CallableStatement =
"DECLARE
a person_type;
BEGIN
a.load_object(4);
? := a;
END;"
And register as an out parameter.

Unable to load mySql Driver in Java class invoked using bpelx:exec

Hi ,
I am trying to connect to mysql database in my java class.when i run this class in Jdeveloper it loads the driver without any problem.I can chk the log in the Jdev messages area.Now I am invoking this class from the BPEL process through <bpelx activity.But when i run my BPEL process it throws runtime exception "classNotFoundException:unable to load com.mysql.jdbc.Driver".I have set the project properties ->libraries to the class path of the mysql jar file as well.
Now if i try to connect with the Oracle driver then it is working fine.
I know this is a classpath issue.Can anyone tell me if there are some other settings to make it work fine.
the java code :
System.out.println("in getConnection method");
Class.forName("com.mysql.jdbc.Driver").newInstance();
System.out.println("loaded Driver :");
String url="jdbc:mysql://ntlv014:3306/wx";
_jdbcConnection = DriverManager.getConnection(url,"development","ber1nger");
System.out.println("Got Connection :"+_jdbcConnection.isClosed());

I think you have 2 options..
either put the jar for the mysql in the classpath on the server...or try something like this :
http://forum.java.sun.com/thread.jspa?forumID=17&threadID=633158
try to put the jar of the mysql into the suitecase of the bpel.
never seen this coming around...so..it's just a wild guess.

OAAM 11g R2: Unable to load java class for custom configurable action

Need to configure a Configurable Action to get triggered for a particular action at a given checkpoint.
Steps Followed:
1. Created a java class implementing com.bharosa.vcrypt.tracker.dynamicactions.intf.DynamicAction, getParameters() and execute() methods were implemented in that java class.
2. Added necessary jars from $ORACLE_IDM_HOME\oaam\cli\lib to the build classpath.
3. Compiled and created a jar with it.
4. Extracted the oracle.oaam.extensions.war file into a working folder.
5. Added the Custom Jar created in step 3 into <working folder>/WEB-INF/lib/
6. Changed the following in MANIFEST.MF in <working folder>/META-INF/:
Specification-Version:11.1.2.0.1
Implementation-Version:11.1.2.0.1
7. Rejar-ed the oracle.oaam.extensions.war from the working folder using following command:
jar -cvfm oracle.oaam.extensions.war <working folder>\META-INF\MANIFEST.MF -C <working folder>/ .
8. Stopped the oaam_admin_server1, oaam_offline_server1 and oaam_server_server1.
9. Deleted the oracle.oaam.extensions deployment from the weblogic.
10. Deployed the newly created oracle.oaam.extensions as a shared library for oaam_admin_server1 and oaam_server_server1.
11. Started all managed servers.
But when I tried to create an action template with the java class I just created, it was throwing following error
+java.lang.ClassNotFoundException: *+

This thread is a bit stale but I thought it might help to clarify one point about custom jar files on UCCX.
To properly load a custom jar:
Upload it into the classpath directory in the document repository.
Select it under System | Custom Classes Configuration
Finally you need to restart the CCX Engine and the CCX Administration services. If you have HA you need to restart them on both servers.
Other notes:
When referencing your class in the CCX Editor, use the fully qualified name of the class. Lots of other classes use things like Element or Document so you need to be explicit. The editor only knows about the 20 native classes by their object names. If you create a Document object in the editor you are really creating a com.cisco.doc.Document object. If you loaded jdom.jar and you wanted a jdom document then you need to create an object of type org.jdom.Document.
When compiling your custom jar files, be sure to compile for the version of Java that the CCX Engine runs. In general UCCX 7.X and older use Java 1.4. UCCX 8.X and higher use Java 1.6. Several of the core Java classes had significant changes between 1.4 and 1.6. If you ran your code on UCCX 7 or earlier and now it fails in UCCX 8.X or higher, recomplile for Java 1.6 and you classes will likely work again.
Finally, check for security violations in UCCX 8.X or higher. Cisco has restricted some of the things you can do. These URL's have more information:

Using java class and variables declared in java file in jsp

hi everyone
i m trying to seperate business logic form web layer. i don't know i am doing in a right way or not.
i wanted to access my own java class and its variables in jsp.
for this i created java file like this
package ris;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class NewClass{
    public static void main(String args[]){
        Connection con = null;
        ResultSet rs=null;
        Statement smt=null;
        try{
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
            smt=con.createStatement();
           rs= smt.executeQuery("SELECT * FROM emp");
           while(rs.next()){
            String str = rs.getString("Name");
            }catch( Exception e){
                String msg="Exception:"+e.getMessage();
            }finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
}next i created a jsp where i want to access String str defined in java class above.

Very bad approach
1) Think if your table contains more than one NAMEs then you will get only the last one with your code.
2) Your String is declared as local variable in the method.
3) You have not created any object of NewClass nor called the method in JSP page. Then who will call the method to run sql?
4) Your NewClass contains main method which will not work in web application, it's not standalone desktop application so remove main.
Better create an ArrayList and then call the method of NewClass and then store the data into ArrayList and return the ArrayList.
It should look like
{code:java}
package ris;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class NewClass{
    public static ArrayList getNames(){
        Connection con = null;
        ResultSet rs=null;
        Statement smt=null;
        ArrayList nameList = new ArrayList();
        try{
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
            smt=con.createStatement();
           rs= smt.executeQuery("SELECT * FROM emp");
           while(rs.next()){
            nameList.add(rs.getString("Name"));
           return nameList;
            }catch( Exception e){
                String msg="Exception:"+e.getMessage();
               </code><code class="jive-code jive-java"><font>return nameList;</code><code class="jive-code jive-java">
            }finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
      </code><code>return nameList;</code>

How to convert a .jsp to a .java/.class file for use in peoplesoft

Hi java/jsp experts,
I want to convert a .jsp to a .java/.class file. is there a tool available, please let me know if you have any pointers....
or can i do it manually:
these are a few lines that the .jsp contains, and i would like to translate this to be in .java/.class format:
<%@ page import="sun.misc.BASE64Encoder, javax.crypto., javax.crypto.spec."%>
<%@ page import="java.util.StringTokenizer" %>
<%@ page import="java.util.Map" %>
<%!
sb.append("<input type=\"hidden\" name=\"orderPage_serialNumber\" value=\"");
sb.append(serialNumber);
sb.append("\">\n");
return sb.toString();
%>
how can i translate the above import statements and html elements from jsp to java, please let me know.
Once i have the .java file created from the .jsp, I will compile .java to create the .class file and invoke the .class in peoplecode by using java apis available in peopletools.
Thanks in advance.

Is there a way convert a binary .exe file( compiled by
another compiler) into Java .class/.jar file ? Anyone
know of a free program that can do this?It's not possible. There are many decompilers and disassemblers for Java but nothing will take you from ANY binary to Java source. It would be the end of computing as we know it and the beginning of a new era -:)

How to convert dll to a java class file?

Hi folks:
I have some DLLs in VB and C++ and I wanna to convert them to a java class file. Does anybody know if exist a sw or easy way to do it?
thanks

Well, I believe you could write JNI to call the functions in the DLLs, although I wouldn't recommend it. (You'd have a non-portable, fragile result.)

I'm not sure about the issue. Are you talking about "servelets"? "RMI"? Take a look at those issues.

How do I call a simple java class from a bpel process?

Hi.
In JDeveloper 10.1.4.3.0 I've created a simple java class that does an ftp get operation followed by an unzip. The class uses some 3rd part libraries (jars).
I want to use a simple bpel process to schedule a daily execution of this java class, and deploy it all to our SOA-server, - and was looking into using the <bpelx:exec> function.
The java class and the bpel process is all stored in the same JDeveloper project.
How do I put this together so that both my java class and the necessary jars are available to the bpel process?
I've looked into the JavaExecSample.bpel, and it's says something about "...the class com.otn.samples.javaexec.CreditCalculator is locally packaged with this BPEL process".
How do I do that?
Can I make it and test it all locally from my workstation (only JDeveloper installed, I guess there's nothing that can execute the bpel code?), or do I have to compile class etc (make war-file?) and deploy to SOA server (BPEL-INF/lib or classes?) before anything can be tested?
(I guess all this is simple, once you know how, but being a newbie to this I need a shove in the right direction :-)
Regards,
-Haakon-

To create a java class and dependent jars inside the BPEL process project you need to do the following:
1. Right click on your BPEL process project and select New and then Java Class from the Items.
2. Make the BPEL process project, JDeveloper would compile the java classes and add them into the BPEL suite case jar, see the output folder and check the BPEL suite case jar file for java classes and dependent jars.
You can test your Java classes from JDeveloper IDE, no need to deploy the classes on SOA server. When you make the BPEL project it compiles .bpel files and Java classes. You can test your classes once .bpel file and java classes compiled successfully.

Dharmendra

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!

How can I call a java class from within my program?

I was wondering if there's a platform independent way to call a java class from my program.

Here's my scenario. I'm working on a platform independent, feature rich, object-oriented command prompt program. The way I'm designing it is that users can drop classes they write into my bin directory and gain access to the class through my program. For example, they drop a class named Network.class in the bin directory. They would type Network network at my command prompt and gain access to all the methods available in that class. They can then type system.echo network.ipaddress() at my prompt and get the system's ip address. I have it designed that there's a server running in the background and the clients connect to my port. Once connected the end-user can enter their user name and password and gain access to the system. When they type a command they actually call another java program which connects to my server using a seperate thread. They can then communicate back and forth. I have it set that everything has a process id and it's used to keep track of who called what program. Once the program is done it disconnects and closes. Rather than getting into the nitty gritty (I didn't want to get into heavy detail, I know how everything will work) I'm really interested in finding out how I can call a java program from my program. I don't want it to be part of the app in any way.
