Forms 10g R2 and Java Bean Interaction

Hi,
I need some help.
I have a Forms app and a Java app that i need to communicate between them.
The Java app send and receive events. How i send and receive events in Forms 10g.
What you recommend to do that.
Thank You. JP.

There is a very good example in the otn in the forms-demo-section.

Create XML dynamically from schema and Java bean

Hi,
I'm looking for suggestions on the best approach to create an XML file programatically from a schema and Java bean.
The schema used is not fixed and may vary with each request so a dynamic way to create the XML is required.
Is there an API available that allows me to achieve this easily? Any help would be appreciated to point me in the right direction.
Thanks.

XMLBeans or JAXB should work for you.

Popup menus in Forms 10g and Java Bean

Hi all.
What class in Java corresponds with popup menus(not in menu module) ?
I know that oracle.ewt.lwAWT.lwMenu.LWPopupMenu is corresponds with MenuBar's submenu. I can find Buttons, Text Fields, Menu and other components in my Form-Applet, but I don't know how to find popup menus in forms through Java Bean...

Hello François,
I have created a java bean that dynamically creates a popup by left-clicking on the bean.
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item' ) ;
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_SEPARATOR', '' ) ;
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item one' ) ;
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item two' ) ;
My problem is the layout. I want to simulate a button. I can't put the bean transparent over a button and I can't simulate a button with the bean.
How can I add the popup functionality to a button and not only to the bean? Or any other workaround?
Regards Pedro.

Forms 6i and Java Bean

Hi
I need to establish communication between my forms and java code.
i have made a java bean and set the implementation class path(i.e the package path (oracle.forms.demo for the bean class)) in the form item.
I want to know where exactly should put the java code or do i have to make modification in any of the environment variables to allow the forms to acces the java code.
what exactly is a java class and do i need to have a wrapper class also to implement the java bean.
please respond fast as i need this info urgently...any small info might prove fruitful
Thanks

Hello,
All you have to do is to copy the .jar file that contains the Java class(es) in the <devsuite>/forms/java/ directory, configur the <devsuite>/forms/server/formsweb.cfg file to add this jar file to the archive_jini tag to indicate where Forms have to load the classes:
archive_jini=frmall_jinit.jar,...,my_jar_file.jar
Then after, you have 2 possibilities:
- the bean does not have any "screen" representation so you can just handle its functions with the Forms internal FBean package functions (no need to put implementation class on the bean area item property)
- it has a screen representation, so you put its implementation class like you did, and you set its properties with the Set_Custom_Property() built-in and get its properties with the Get_Custom_Property() built-in.

How to include PJC and Java Beans in forms

I have tried a lot to include java codes in my forms ..So I decide to start with ProgressBarPJC(cause it is tested and provided with demo) but I could not set implementation class of java bean object to
oracle.forms.demos.ProgressBarPJC it does not accept it but it accept ProgressBar instead of ProgressBarPJC. I don't know why? I have made changes in Forms90_builder_classpath to access f90all.jar and progressbar.jar. I have Progressbar.class and progressbarpjc.classs both but i don't know how to set implementation class to ProgressBarPJC.
don't you think there is lots of configuration and path setting to use any JPC or Jar in forms? I am totally confused with this integration.
Please solve this matter
Thanking you,
Neeraj

Reading Forms Key Mappings from java bean - how ?

I want to be able to invoke key trigger code in a Forms 10g run-time from a java bean (extends BeanWrapper) either by:
a) using inherited method calls passing the KeyEvent retrieved from my listener, or
b) dispatching a custom event from the bean with a parameter value which identifies the key trigger to process (not the key code & modifier string).
On a), I've not been able to identify any method in the BeanWrapper hierarchy tree that might help me do this, and samples like (http://forms.pjc.bean.over-blog.com/categorie-465294.html) seem to imply that no such method exists.
In terms of b), the oracle.forms.engine.KeyMapTable class seems to be what I want (seems to translate the KeyEvent into a FormAction/string using server settings), but getting a hold of this object through (oracle.forms.engine.Main)getHandler().getApplet() doesn't seem possible.
How are others invoking eg: key-crerec from a Forms 10g bean component in a way which is sensitive to server key mappings ?
Thanks in advance for your help.

I have no experience with KeyEvents in Forms, but if the KeyMapTable class really is the solution, can't you just instantiate one yourself.
Looking at the constructor it only needs a single argument, the oracle.forms.engine.Runform class. You should be able to get a handle on it with:
IHandler hander = getHandler();
if (handler instanceof UICommon) {
UICommon u = (UICommon)handler;
// u.getDispatcher() should get oracle.forms.engine.Runform
}Not sure if it will work, but you can give it a try.
I love pushing the PJC and Oracle Forms applet to its limits. Not really sure if Oracle intended the PJC framework to do stuff like this, but it sure would have helped if they have JavaDoc about the oracle.forms.* classes

Forms 10g installed and running on Windows Vista

<font color=0000FF>Update 12-Dec-2008: </font>Oracle has published NOTE 559067.1 -- How to Install Developer Suite 10.1.2.0.2 - hence 10.1.2.3 - on Windows Vista, 24-OCT-2008 with some installation help.
<font color=0000FF>Update 07-July-2008: </font> Added text at the bottom showing how to find patchsets for Forms 10g.
<font color=0000FF>Update 29-May-2008: </font> This thread was started in November, 2007. In January, 2008, Oracle released Patch 3 for Forms 10g, which makes Forms 10g compatible with Windows Vista. As time permits I'll try to keep the information in this post up to date. Updated information will be inserted <font color=0000FF>as blue text.
</font>
<font color=0000FF>Original message begins here:</font>
This is a second thread I am posting to outline the steps I have used to install Forms on a Windows Vista Home Basic laptop. The other thread describes installing Forms 6i:
Forms 6i installed and running on Windows Vista
Please read through the initial part of that post for the background. I realize Oracle has not certified Forms 10g to run on Vista, but the time has come for my associates and I to upgrade our old computers to new desktop/laptop platforms, and I would hate to acquire XP machines and be stuck with them for the next 5 years. <font color=0000FF>(Note: Since first posting this message, Oracle has certified Forms 10g Patch 3 (version 10.1.2.3.0) to run on Vista)</font> So after another person informed me that he had Forms installed and running on Vista, I went ahead and bought one. I found that as long as I set the compatibility mode to run Forms programs as Windows XP (and a few other changes), Forms 6i and 10g run quite satisfactorily.
<font color=0000FF>Update 29-Jan-2008: </font> Unfortunately, it turns out that the Forms 10g Builder running on Vista <font color=0000FF>had</font> a major flaw: If you try to develop a form, the Builder will crash if you try to compile a procedure that calls another procedure in the form that has errors. The problem is reported and described in this thread: Error compiling a form under Vista
<font color=0000FF>Update 12-Mar-2008: </font> Installing Patch 3 on Vista does not help with this problem -- the Builder still crashes in the same situation.
<font color=0000FF>Update 25-July-2008: </font> Applying Patch 7047034 has corrected the problem. See this link within this thread: Forms 10g: Installing Patch 7047034 on Windows Vista
Webutil note: I am stuck in a Forms 6i client/server world, so all my forms must run in that environment. Therefore I have not used any Webutil software, and I do not know whether that part will run under Vista.
Internet Explorer note: On Windows Vista, IE CANNOT be used to run the Web Forms runtime. It crashes immediately when you try to run a form. Instead, I can use either Firefox (Firefox 2, Firefox 3.0 Crashes with Forms 10g) or Netscape, as long as they are set to disable java. <font color=0000FF>[ Correction:   IE7 on Vista now runs the Forms 10g forms.   You just need to add "?config=jpi" to the browser URL when starting the Web Forms session.

The Oracle Developer Suite download page:
http://www.oracle.com/technology/software/products/ids/index.html
Oracle Developer Suite Installation Guide:
http://download.oracle.com/docs/cd/B25016_07//doc/dl/core/B16012_04/toc.htm
The steps below are those I followed to install Forms 10g (version 10.1.2.0.2)
I. Preliminary system changes in Windows
When I started installing, I got the following error message:    Install has encountered an error while
    attempting to verify your virtual memory settings.
    Please verify that the sum of the initial sizes of
    the paging files is at least 256 MB.To fix this: Go to Control Panel, System and Maintenance, View amount of RAM and processor speed (under "System"),
Advanced system settings (in left "Tasks" column), Advanced tab, Settings (under "performance"), Advanced tab:
Virtual Memory shows a "Total paging file size for all drives: 2337MB.
Click "change", Uncheck "Automatically manage paging file size for all drives"
Click "custom size:", set Initial size to: 2048, Max to 4096
Click set button, then OK, get message:The changes you have made require you to restart your computer before
   they can take effect.Restart the computer.
II. Installing Forms 10g
1. Download two files from Oracle:
ds_windows_x86_101202_disk1.zip (626,122,752 bytes)
ds_windows_x86_101202_disk2.zip (236,880,881 bytes)
2a. Before extracting, it is a good idea to shut down any virus protection software. It can sometimes prevent some files from being created.
2b. Extract both into the C:\oracle directory, as disk1 and disk2.
3. Using Windows Explorer, change the properties of setup.exe in the C:\oracle\disk1 folder. (In windows explorer, right click, properties, Compatibility tab.) Change the compatibility to run as Windows XP (Service Pack 2).
4. Right click setup.exe and click "Run as administrator"
5. Select "Installation type" = Complete (1.11 GB)
6. Received this message:Windows Firewall has blocked this program from
accepting incoming network connections. If you
unblock this program, it will be unblocked on all
public networks that you connect to.
C:\users\steve\appdata\local\temp\orainstall...
2007-10-29_11-59-08am\jre\1.4.2\bin\javaw.exeI clicked "Unblock"
7. Received this message: "Provide outgoing mail server information" I entered the smtp mail server that I use.
8. A summary screen displayed showing 274 products under New Installations.
I clicked the Install button.
9. Received this message: You can find a log of this install session at:
C:\Program Files\Oracle\Inventory\logs\installActions2007.....log
10. The installation completed. Installed products shows Forms 10.1.2.0.2
III. After the install completed
1. Create a shortcut to the Forms 10 Builder on the Desktop.
On the shortcut line, after the .exe, add *userid=userxxx/pwxxx@orcl* so Builder automatically logs into 10g database. If you do step 4 below (creating an easily-accessible folder to use for your forms) change the "Start in" path on the shortcut so it points to that folder. Otherwise, Forms Builder will not find referenced objects and PLL libraries when it opens a form. Also do the same on the Start, All Programs shortcut for the Forms Builder.
Edit: After applying Patch 3, the following steps are not necessary.
Set its compatibility to Windows XP.
Set checkbox: "Run this program as as an administrator." (Without this, FormBuilder will NOT open a PLL library.)
Click the "Show settings for all users" and change values there.
2. Copy "Start OC4J Instance" icon to desktop.
Set its compatibility to Windows XP.
The first time it runs, I got a Windows popup to unblock program named Java. I clicked "Unblock".
3. tnsnames.ora:
Rename C:\oracle\DevSuiteHome_1\network\admin\tnsnames.ora
to: tnsnames_orig.ora
If you created a tnsnames.ora file for Forms 6i, just copy it to the path above. If not, do this:
Create a new tnsnames.ora file, copying entries old file on my old laptop, which contains all the connections I use.
Delete the old laptop entry, replace with new entry for the new local ORCL connection on new laptop from tnsnames file renamed from the c:\oracle\... ...\10.2.0\db_1\ path.
4. Optional: Create an easily accessible folder to store fmb files:
C:\users\steve\.1\fmb10
You don't really want to keep drilling into C:\oracle\DevSuiteHome_1\forms, and then find your .fmb file among the several dozen oracle-supplied files.
To create a folder named .1, you have to open a CMD.exe (Windows DOS) window, and type the Make Directory command:
MD .1
That will create the folder within the current directory -- mine defaults to C:\users\steve
Note: If you also need to use Forms 6i like me, DO NOT EVER open a .fmb file in the Forms 10 Builder from the Forms 6i folder. If you compile it, or even worse, save the .fmb, Forms 6i *cannot ever* access the file. Instead, always use the File Manager (Windows Explorer) to copy the fmb from the fmb6 folder into the fmb10 location.
5. Change the Forms 10g Default.env file using a text editor.
This file replaces all the settings originally written to the Windows Registry (GREAT idea, Oracle! I hate the registry.) No more Regedit. The default.env file is located at: (DevSuiteHome_1 path)\forms\server\default.env
Locate line with: FORMS_PATH= and add:
;C:\users\steve\.1\fmb10
Add a new line:
FORMS_MMAP=FALSE
The above allows compiling an fmx while the form is running.
Add a new line:
FORMS_ROWLOCK_OPTIMIZATION=FALSE
(This fixes Oracle bug number 3949854, which prevents automatic skipping if the same value is typed over another value. TAR 4806199.993 Automatic Skip failure...) See bug 4068896
Add a new Line:
FORMS_RESTRICT_ENTER_QUERY=False
This allows use of Query-Where window in enter query, after entering a colon in any input field. Without this, Forms returns FRM-40367: Invalid criteria in field nnn in example record. Oracle shut it down to prevent "sql injection" attacks.
6. Jiniator setup:
Run file jinit.exe in C:\oracle\DevSuiteHime_1\jinit\jinit.exe
It installs Jinitiator 1.3.1.22.
I installed it in C:\oracle\JInitiator 1.3.1.22\
For Firefox, make sure a copy of file \bin\NPJinit13122.dll resides in C:\Program Files\Mozilla Firefox\plugins.
For Netscape, the path is: C:\Program Files\Netscape\Navigator 9\plugins
7. Browser settings
See the note above about using Firefox 2 and not Firefox 3!
In Firefox 2 go to: Tools-> Options-> Content
Uncheck the "Enable Java" checkbox
--Firefox terminates if this is not done!
Note: After my system automatically installed updates to either java or Firefox, re-check the "Enable Java" setting. I am suspicious that one of these installs re-enables java in the browser.
Also note: some web sites cannot display properly if java is disabled. Example: U.S. time website: http://www.time.gov Use Internet Explorer to view these.
In Netscape make the same changes as Firefox. Without disabling java, it also terminates when you try to run a form.
Creating a url to use in the browser:
Try this:
http://127.0.0.1:8889/forms/frmservlet
If it does not work, change the 8889 port number as follows:
Open file: C:\oracle\DevSuiteHome_1\install\portlist.ini
Note the number in line:
Oracle Developer Suite HTTP port = 8889
Use the number as the port number.
You can also change the 127.0.0.1 to the computer name:
Control Panel, System and Maintenance, See the name of this computer (under "System"). Mine is "steve-PC"
So the alternate URL is: http://steve-PC:8889/forms/frmservlet
To try out the URL, start the OC4J instance set up above. Then start either Netscape or Firefox, and enter the URL. You should get a welcome screen.
If the above URL works, start up the Forms Builder, and open Edit, Preferences. On the General tab, uncheck the "Build before running" check box (optional). On the Runtime tab, set the "Application Server URL to the url above.
To run a real form, add this to the URL after frmservlet, (with no spaces):
?form={formname}&userid={userxxx}/{passwordyyy}@{connect-string}
but replace the parts in curly braces with the appropriate values. Example:
http://127.0.0.1:8889/forms/frmservlet?form=ABC&userid=abc123/zyx@orcl
Setting up Forms Builder to directly run a form in the browser:
Run the Forms Builder. Go to Edit, Preferences, Runtime tab.
Set the Application Server URL to:
http://127.0.0.1:8889/forms/frmservlet
(or use whatever URL string you developed above)
Set the Web Browser Location to:
"C:\Program Files\Netscape\Navigator 9\navigator.exe"
(or an equivalent to run the Firefox browser).
8. FORMSWEB.CFG file changes
The file is located at:
C:\ORA_DS_101202\DevSuiteHome_1\forms\server\formsweb.cfg
I changed the following two lines in the file, but these are my personal preferences:
separateFrame=true
lookandfeel=Generic
9. FMRWEB.RES file changes
For Oracle help: Enabling Key Mappings
The file fmrweb.res defines actions (triggers that run) when a function key is pressed while running Forms. The one released has unix-style key mapping, but I prefer keys originally mapped for Windows PC Forms users. There is a fmrpcweb.res in the same folder that can be renamed to fmrweb.res.
In the C:\oracle\DevSuiteHome_1\forms path, I renamed fmrweb.res to fmrweb_orig.res.
I have a file that I prefer to use, so I put it into the folder as fmrweb.res. The contents are listed below. It is organized so the most important keys are listed alphabetically at the top (URFD column is the sort column), followed by a group of less-important keys. These are keys that are available to users, but they either would not use, or are disabled within most forms. The URFD column in the second set starts with a hex A0 character, which is a high-order space, so collates after normal alphabetic characters. (Note: If you want to copy the text below and use it, the hex A0 character has been changed by the forum software to a space. So you would need to use a text editor with hexadecimal character capabilities to replace the space with the original character. )
My file has special keys defined for F2 (I use it for a debugging Key-F2 trigger in my forms), and a "Cursor to Home" F12 function. All the rest are pretty much the same as in the released fmrpcweb.res file, only mine are organized alphabetically on the URFD column.
The Web Forms fmrweb.res file is editable using any programming editor (NOT MS Word!!!). The old Client/Server key mapping file, fmrusw.res, could only be changed using the Oracle Terminal program (and it is a pain to use).
Here is the main part of my fmrweb.res file:#

I followed your instructions and installed Developer Suite 10G on Windows Vista Home Premium edition. I have Oracle 11G DB running on the same machine.
Two points, Steve:
1. When I tried to set the maximum virtual memory to 6110 an error message displayed from Windows and told me that I can't set the maximum virtual memory to more than 4096. I set it to 4090 and it worked and I got nothing wrong during the installation process.
2. After installing JInitiator and disabling Java on Firefox I called the http://127.0.0.1:8889/forms/frmservlet page and everything seemed to be OK because the Oracle Forms Services logo appeared and then a successful installation message appeared , but as I clicked (ok) to continue a gray screen appeared inside the browser (like the one displayed when you try to run a Java applet inside a browser) and then I wait to death till something appears but sadly nothing. I just get a blank gray screen inside my Firefox browser.
Do you have any idea what to do to solve the problem?

Ok, this seems to be a long and convoluted path to do absolutely nothing.
You submit the form.
You run a servlet that gets the parameters correctly (good), creates a SimpleBean (good) and then sets this into request attribute space under the names "user" and "pass" - (why?)
You then forward to the jsp: submit.jsp.
Submit.jsp creates a new SimpleBean, and attempts to populate it with <jsp:setProperty>. You then call the issueData method on it.
Your complaint: Rows are being created in the database which have empty string values instead of the parameters you have passed.
So, why are the values blank? Where do you think these values should be coming from?
Looking at SimpleBean we find one mistake - you have mis-named your get/set methods.
To properly follow java beans standards, you should use camel-case for your methods.
Rather than getuserName() the method should be getUserName(). getpassword() should be getPassword() etc etc.
The method getUserName() defines a property "userName" for the bean.
Once that is fixed, lets go to submit.jsp. The <jsp:setProperty> statement will try and set all properties of the bean from the request parameters.
There are no request parameters "userName" or "password" so those values don't get set in the bean, therefore it uses their default value of empty string - "".
There ARE request parameters called "user" and "pass" but because they aren't properties of the bean, they get ignored.
As a result, the values are empty string, and that is exactly what gets inserted into the database.
Ways to fix this
1 - rename your parameters on your form to be "userName" and "password" to match the bean. That way the <jsp:setProperty> tag will populate them properly.
or
2 - Call issueData() method from your servlet after you have created the SimpleBean. Better in my opinion as you then don't have any scriptlet code on a JSP page.

First use of jsp and java bean and "Unable to compile class for JSP" error

Hi,
I am trying to create my first jsp + java bean and I get a basic error (but I have no clue what it depends on exactly). Tomcat seems to cannot find my class file in the path. Maybe it is because I did not create a web.xml file. Did I forgot to put a line in my jsp file to import my bean?
Thank you very much for your help.
Here is my error:
An error occurred at line: 2 in the jsp file: /login.jsp
Generated servlet error:
[javac] Compiling 1 source file
/usr/local/tomcat/jakarta-tomcat-5/build/work/Catalina/localhost/test/org/apache/jsp/login_jsp.java:43: cannot resolve symbol
symbol : class CMBConnect
location: class org.apache.jsp.login_jsp
CMBConnect test = null;
I only have this in my directory:
test/login.jsp
test/WEB-INF/classes/CMBConnect.java
test/WEB-INF/classes/CMBConnect.class
Do I need to declare another directory in classes to put my class file in it and package my bean differently?
Here is my login.jsp:
<%@ page errorPage="error.jsp" %>
<jsp:useBean id="test" type="CMBConnect" scope="session" />
<html>
<head>
<title>my test</title>
</head>
<body>
<h3>Login information</h3>
<b><%=session.getValue("customerinfo.message")%></b>
<form> ....... </form>
</body>
</html>
and here is my CMBConnect.java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class CMBConnect
public CMBConnect () { }
public String openConnection(String id, String password) {
String returnText = "";
try {
Connection con = null;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
con = DriverManager.getConnection("jdbc:oracle:thin:@myserver.abc.com:1521:TEST", id, password);
if(con.isClosed())
returnText = "Cannot connect to Oracle server using TCP/IP...";
else
returnText = "Connection successful";
} catch (Exception e) { returnText = returnText + e; }
return returnText;
Thanks again!

New to Jsp. Jsp and java bean not running

hi
i have created a simple jsp file and using a java bean. but it is showing errors. my file directory structure in tomcat4.1 is:
aptechsamples:
index.jsp
WEB-INF/classes:
myPackage:
Counter.class
i have no web.xml file i dont know how to use it or not. i need it or not.
the index.jsp file:<html>
<head><title> A Simple JSP Bean </title></head>
<body>
<%@ page language ="java" %>
<%@ page import ="mypackage.Counter" %>
<jsp:useBean id="id_counter" scope="session" class ="Counter"/>
<jsp:setProperty name="id_counter" property="count" param="count" />
<jsp:getProperty name="id_counter" property="count" />
</body>
</html>the Counter.java file is: package mypackage;
public class Counter{
     String msg;
     public Counter(){
          msg = "Hello World";
     public String getCount(){
          return msg;
     public void setCount(String c){
          msg = c;
}please help me and tellme what the hell is wrong with it or me. im getting an error:
exception
org.apache.jasper.JasperException: Cannot create bean of class Counter

Java is already telling you what is wrong: it cannot create an instance of your Counter class. The reason being: it can't find it.
What do you mean by "myPackage"? Before you can use any class in your JSP's or servlets, they MUST be stored in a package. If you don't know what that is, I highly suggest you lookup "java package" and "java classpath" using google.
Let's say your Counter class is in a package mypackage (so it starts with the line package mypackage;). Then you have to store the .class file as:
WEB-INF/classes/mypackage/Counter.class
If done correctly, the error message should disappear.

Page Flow and Java Control interaction

Hi everybody !
Even after to read some documents like
http://dev2dev.bea.com/pub/a/2004/06/wlw_internals.html
and
http://dev2dev.bea.com/pub/a/2004/01/jones.html
i still didn't get what is really happening "behind the scenes" between Page Flows and Java Controls (Workshop 8.1). I would be glad if anyone could send to me more detailed documentation or explanation about this subject.
How can a Java Control to stand behind a Stateless Session Bean (GenericStatelessSLSB) and still to keep its internal state (instance variables) consistent ? How can a statefull Java Control to remain statefull being accessed by a stateless component (the EJB) ? Or is the source code of a Java Control (the JCS file) kept by the Page Flow and sent to EJB for its execution ?
Thanks in advance.

Hi Daniel
I have attached a doc I created that explains what happens behind the scenes
when a pageflow call a JCS va a JWS calling a JCS.
Can you please go through the document and let me know any questions you may
have?
Thanks

Need advice about web services and Java beans

Hi
I am very new to web services and to Java beans as well.
I am trying to understand if and how a web service can use functionality I have in a Java bean. I couldn't find any documentation I can use.
For example:
InitialContext ic = new InitialContext();
Adder adder = (Adder) ic.lookup("ejb/AdderJNDI");In a EJB client project (I'm working with Eclipse) if I add the EJB project to the build path, the Adder interface is recognized.
Theoritacally I thought I can do the same in a web service server project, but the Adder interface is not recognized.
Is there something I can read to understand how I need to use the EJB or implement the web service?
Many thanks
Sigal

Okay....I think I made some errors with the original scenario:
It basically comes down to this....I think. OCS Calendar has a set of Java classes and methods that provide an abstraction for their web services interface. I know how to create something to use these classes using an IDE like JDeveloper, but I'm not sure how that would work with HTML DB.
I've noticed that the SQL Workshop has a place for Java sources and classes, and I've heard mentions of PL/SQL wrapping. Is there a way to import classes into an HTML DB workspace, wrap 'em up, and access them via PL/SQL?
Thanks again,
Jonathan

Forms 10g, OAS and Web Services.... help!

Hello,
We're in the middle of a project that was originally supposed to be a (simple :D) upgrade of an existing Forms 6i application to a Forms 10g application.
During the course of the project we have encountered various problems with the older forms (shakes fist at Headstart code...) and as a side effect have had to upgrade our OAS to 10.1.2.0 (10gR2). That's fine, however we have recently been looking into replacing the C++ code that the old application uses to connect to SAP with a new Web Services system, using the SAP Adapter and WSDLs and BPEL and all the rest of it (steep learning curve).
In setting that up it seems it would be advisable for us to upgrade to 10.1.3.x (or "get a headache" said Oracle Support...) However, I now read (in an article from July last year) that Forms and Reports are not supported in 10.1.3.x...
So, do we ask our DBAs to go ahead and install the SOA suite 10.1.3.x? And if so, do I need to do something else to support our !0gR2 forms? Or will they just work? Can we do a "clean" install of 10.1.3.x or do we upgrade the existing 10.1.2.0 system....? Colour me confused.
Help!
Thanks in advance
Dan

You are correct, Forms 10gR2 is the latest and is not available on the 10.1.3 stack. I am also not sure if you are talking about writing web services or just consuming them. However you have 2 main options.
you can install 10.1.2 and use 10.1.2 for Forms and use 10.1.2 for your web services - this should work ok but of course you are "handicapped" by only being able to use 10.1.2 features of BPEL and WS.
Next option, you can install 10.1.2 for running Forms and run a separate 10.1.3 for running BPEL and SOA suite - nothing wrong with that. And if you write a web service and deploy to 10.1.3 you can call that from Forms.
Example of calling an external web service from Forms

http://www.oracle.com/technology/products/forms/forms_modernization.html - calling a BPEL process is just like calling a web services
