Convert form to java without formsWizard

Hi
It's possible to reversed fmb generating spesification from oracle designer and then this spesification convert to java.
I know that form can converted to java used formsWizard but i think have another way to do this, i don't this possible or not.
Anybody have idea?

Convert Oracle Forms into Java (swing & JSP's)

Dear All,
We are currently in the process of evaluating our upgrade of system, which is using forms 4.5. One of the options we are considering at this stage is converting all forms into Java program. I am currently doing some pilot work on this project. I am using FormsWizard, a product of InformatikAtelier Gmbh, along with Forms 6i and Jdeveloper 9i. Has any one done this before in this group? Your assistance is much appreciated.
Regards

Grant, Thanks for that mail. It was very useful article. The article has lots of brilliant points consider. I may have to discuss with our System Architect. With my experience in both forms and Java, it is hard to justify the business benefit out of this conversion. We are a strong Oracle house and have no intention of moving towards J2EE at this stage.. Thanks once again.

Converting oracle forms into java forms

Hi all,,
would help me plz on how to convert oracle forms into java using any tool;
Is Jheadstart is the tool,, im having jeveloper version 10.1.2.1.0

There are at least two companies that are marketing Forms to Java conversion tools. I'm sure that a good Google search will locate them, and they are frequent exhibitors at Oracle-oriented conferences like Collaborate and ODTUG Kaleidoscope. But there are problems associated with doing this. I urge anyone who is considering such a project to read this article by Grant Ronald: http://www.oracle.com/technology/products/forms/pdf/10gR2/formsmigration.pdf
You should carefully ask yourself and your clients and management, "Why do you want to do this?", "What benefits are you trying to realize?", "Does this make sense, and are there other options that we should be exploring?"
For instance, many people are trying to protect themselves because "Forms is going away". Oracle has stated again and again that Forms is NOT going away. In fact the recent Fusion Middleware 11g release included a new version of Forms with some significant enhancements. You may do very well just by upgrading to the latest version of Forms.
If you do decide that it still makes sense to convert, I suggest that rather that converting, you may want to redevelop from scratch. Keep the database if it is well designed - a well designed, stable database will outlast any front end that you may use against it. Then take full advantage of the capabilities of your new toolset, and leave behind the limitations and inapplicable methodologies of your old one. Oh, by the way, don't use JDeveloper 10.1.2. Use 11g if you can, or 10.1.3.5 if you must.

Converting html forms to java

having viewed an earlier post in this forum i managed to create the following code but am having a few problems.
here are the active parts of the html form on googles search, engine. i am trying to convert this into java form and have so far succeeeded in generating the code shown below, but keep getting the following error
"IOException; Server returned HTTP response code: 501 for URL: http://www.google.co.uk/search"
the form:
<form action=/search name=f>
<input type=hidden name=hl value=en>

<input type=submit value="Google Search" name=btnG>
<input type=submit value="I'm Feeling Lucky" name=btnI>
</form>
in the following code baseURL is the domain of the server... in this case http://www.google.co.uk/, method is the method as defined in the form method attirbute, if the attribute is not there, as in this form the default method is called which is GET

        }i also tried self adding in the question mark that appears after the search text bu again get the same error. any ideas what im doing wrong when connecting to the server? thanks in advance for any help

Just saw this topic on the forum,
For each web crawlers the web sites maintain a file called Robots.txt which can be assessed by : http://www.google.co.uk/robots.txt
You would see following on that file :
User-agent: *
Allow: /searchhistory/
Disallow: /search
Disallow: /groups
which means that crawlers are not allowed to scrap this site on search, due to which our code wasnt working
Thanks

Cannot convert type class java.lang.String to class oracle.jbo.domain.Clob

Cannot convert type class java.lang.String to class oracle.jbo.domain.ClobDomain.
Using ADF Business Components I have a JSFF page fragment with an ADF form based on a table with has a column of type CLOB. The data is retrieved from the database and displayed correctly but when any field is changed and submitted the above error occurs. I have just used the drag and drop technique to create the ADF form with a submit button, am I missing a step?
I am using the production release of Jdeveloper11G

Reproduced and filed bug# 7487124
The workaround is to add a custom converter class to your ViewController project like this
package oow2008.view;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
import oracle.jbo.domain.ClobDomain;
import oracle.jbo.domain.DataCreationException;
public class ClobConverter implements Converter {
     public Object getAsObject(FacesContext facesContext,
                               UIComponent uIComponent,
                               String string) {
       try {
         return string != null ? new ClobDomain(string) : null;
       } catch (DataCreationException dce) {
         dce.setAppendCodes(false);
         FacesMessage fm =
           new FacesMessage(FacesMessage.SEVERITY_ERROR,
                            "Invalid Clob Value",
                            dce.getMessage());
         throw new ConverterException(fm);
     public String getAsString(FacesContext facesContext,
                               UIComponent uIComponent,
                               Object object) {
       return object != null ?
              object.toString() :
              null;
}then to register the converter in faces-config.xml like this
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee">
<application>
    <default-render-kit-id>oracle.adf.rich</default-render-kit-id>
</application>
<converter>
    <converter-id>clobConverter</converter-id>
    <converter-class>oow2008.view.ClobConverter</converter-class>
</converter>
</faces-config>then reference this converter in the field for the ClobDomain value like this
          <af:inputText value="#{bindings.Description.inputValue}"
                        label="#{bindings.Description.hints.label}"
                        required="#{bindings.Description.hints.mandatory}"
                        columns="40"
                        maximumLength="#{bindings.Description.hints.precision}"
                        shortDesc="#{bindings.Description.hints.tooltip}"
                        wrap="soft" rows="10">
            <f:validator binding="#{bindings.Description.validator}"/>
            <f:converter converterId="clobConverter"/>
          </af:inputText>

Forms to Java conversion

Hello Gurus,
i have Oracle / Developer 2000 Forms in binary(fmb) and executable(fmx) format , i need them to convert them into Java, is there any tool or conversion method so that i can use as a java program.
Please help me in this regard
Thanks
Qavi

It might also be useful to understand your reasons behind this. We don't specifically advocate migration of Forms to Java but there are some cases where it is required and in this case there are some partners. Read

Convert string into java.sql.Date

Hi,
I want to convert a date in string form into java.sql.Date to persist into the database column with Date as its datatype in Oracle. I'm trying as follows:
import java.sql.Date;
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class DateTest
public static void main(String[] args)
String strDate = "2002-07-16 14:45:01";
     System.out.println("strDate = "+strDate);
Date aDate = null;
try
if(strDate != null && !strDate.trim().equals(""))
     SimpleDateFormat aSDF = new SimpleDateFormat();
     aSDF.applyPattern("yyyy-MM-dd hh:mm:ss");
     java.util.Date utilDate = aSDF.parse(strDate);
System.out.println("utildate = "+utilDate);
     aDate = new Date(utilDate.getTime());
     aDate.setTime(utilDate.getTime());
     System.out.println("aDate = "+aDate);
catch (ParseException e)
System.out.println("Unable to parse the date - "+strDate);
catch (Exception ex)
ex.printStackTrace();
System.out.println("Caught Exception :"+ex.getMessage());
It gives the output as :
strDate = 2002-07-16 14:45:01
utildate = Tue Jul 16 14:45:01 IST 2002
aDate = 2002-07-16
If I put this value into the database table, I can see only the date. Time part is missing. Is this the problem with java.sql.Date or Oracle datatype Date? Please help me asap.
Thanks in advance.
Regards,
Rajapriya.R.

If I put this value into the database table, I can
see only the date. Time part is missing. Is this the
problem with java.sql.Date or Oracle datatype Date?This is not a problem, this is the defined behaviour of the Date type. RTFAPI and have a look at Timestamp, while you're at it.

WHY - give workable examples of using JHeadstart to convert forms into ADF.

Why give examples of how to use JHeadStart to convert forms in to ADF, but not allow it to be done with the evaluation version ... I assume it was possible with the 10g versions. Is it broken in 11g.
I was lookig to build a case for migrating an oracle forms application to Oracle Java and not a IBM or JBOSS or even .Net application, I can't build that case now, I have no budget to engage Oracle, have to do this of my own bat. Company has been take over by bigger company that has IBM stack.
Is Oracle this follish to allow the smaller users of Oralce to go by the way side, be lost to other languages etc

We deliberately did not include the Forms2ADFGenerator in the evaluation version.
Modernizing your forms application, possibly migrating it to ADF is a considerable effort that is often underestimated.
Migration tools like the Forms2ADFGenerator can help to a certain extent but are by no means a magic bullet. This is something we cannot stress enough, as over and over again we see people who think migration tools can make the difference. They cannot.
If you want to make a choice of development environment to modernize your forms application, then the availability of a migration tool should not play a role!
It is a fundamental and strategic decision to go for Oracle ADF which should not be influenced by a minor time saver like a migration tool.
To decide on the use of JHeadstart, the evaluation version with the tutorial should be convincing enough.
The real power of Jheadstart is not in the Forms2ADF Generator, this tool is just a lbonus that can save you a bit of time.
Here is some more info:
When does JHeadstart Forms2ADF Generator save time
The amount of work that can be saved by using the JHeadstart Forms2ADF Generator (JFG) very much depends on the structure of the Oracle Forms application at hand. The JHeadstart Forms2ADF Generator provides most savings for forms that have the following characteristics:
* Standard-Forms data retrieval and data manipulation through blocks based on database tables, with master-detail relations defined between the block
* Complex user interface, many (stacked) canvasses, many tabs, many list of values, and other display types
* PL/SQL logic mostly limited to user interface dynamics: conditionally showing/hiding user interface items, and conditionally changing the properties of user interface items. While JHeadstart does not convert PL/SQL logic, this type of logic is easily implemented in the ADF application because JHeadstart provides many declarative property settings to implement this behavior.
PL.SQL Logic
JHeadstart has made the deliberate choice to not automatically convert the PL/SQL logic to Java. The reasons for this are:
* It is impossible to automate the migration of a two-tier architecture (logic in Forms or in the database) to a three tier Model-View-Controller architecture as is common in JEE web applications, including ADF-based applications.
* The architecture of the converted application should be identical to the best-practice architecture of an ADF application that is build from scratch. If the architecture is the same, the same skill set can be used to maintain both migrated applications and ADF applications build from scratch. In addition, by going for a best practice architecture, the application is more flexible, and can be maintained easier at lower cost.
* When using the JHeadstart Forms2ADF Generator, you get this best-practice ADF architecture that is identical to ADF/JHeadstart applications that are built from scratch.
Other Forms2ADF Considerations
And even if it turns out the JFG adds a lot of value, there are many other questions you should ask yourself before embarking on a Foms2ADF project.
For example:
* Apart from technical reasons like old Forms verisons no longer supported, are there real business reasons and business benefits for migrating that justify the migration effort?
* To what extent is the application still meeting functional requirements?
* Are there issues with stability and end user friendliness?
* Old forms applications are typical "window-on-data" screens, you see the structure of the datamodel through the layout of the screens. Modern web 2.0 composite applications are more task-oriented with good support for human workflow. You should consider to what extent it wants to leverage all these new user interfaces capabilities that come with ADF Faces and WebCenter.
* How does the application fits in the overall IT landscape? What interfaces to other systems exist, what (old/obsolete?) technology is used to implement those interfaces?
* What about batch functionality and reporting facilities?
* May be part of the functionality of the current system can be replaced with standard off-the-shelf software?
* How sound, well structured and future proof is the underlying datamodel?
* To what extent are you looking at service-orientated architectures? Whats the SOA maturity level of your organisation?
* Above questions help to answer the key question: how desirable and benficial is it to migrate an old monolitic forms application 1:1 to a monolitic ADF aplication? How does that fit in overall IT strategy?
* Organisational isues: who will migrate the system, who will maintain the system? Is outsourcing considered? etc.
Next Steps
We offer a Forms2ADF assessment service in which we migrate a number of sample forms selected by the customer to assess the added value of the JFG, and we discuss all of the above questions
For example, I did one Forms2ADF assessment where it turned out that JFG added litlle or no value, but we were still able to convince the customer of the combined power of ADF and JHeadstart in (re-)building ADF apps from scratch.
You also might want to take a look at some presentations I did on this topic, and some online demo's:
* Guidelines for moving from Oracle Forms to Oracle ADF and SOA: http://www.slideshare.net/stevendavelaar/forms2-adfsoa-ukoug
* JHeadstart Forms2ADF Generator – Migrating from Oracle Forms to a Best-Practice ADF application: http://www.slideshare.net/stevendavelaar/jhs11-forms2-adfukoug
* 3 online demo's of forms2adf conversion process: http://www.oracle.com/technetwork/developer-tools/jheadstart/overview/index.html

Converting XML to Java in STB

I am trying to convert xml to java. Looking for simple and light way to covert xml to java in STB.

Heh - all the tags in your question got stripped out by the forum-to-email bridge :-)
Anyway, basically you just parse the XML data. You can use some
kind of library if you like, but it turns out that parsing an XML response
that's consistently formatted the same way isn't all that hard to do directly.
In the HD cookbook project, we have a sample xlet that does just this, reading
weather data from some public web service out there (I forget which - maybe
Yahoo's?) The xlet could be converted to work on MHP or OCAP without
much work. This demo is in xlets/demos/weatherWidget, and the project
is at http://hdcookbook.com, click on the sumo wrestler. It's in the source-code repository,
but over on the right one of the links will let you browse individual files, which should
get you pretty quickly to the XML parser in this demo.
By the way, if you have a choice between JSON and XML in this environment, I'd
personally go with JSON. It's simpler to parse and faster - indeed, see
com.hdcookbook.grin.util.JsonIO in the cookbook repository. Of course, if you're
interacting with a server under your control and you want maximum performance, you
can use a more efficient binary format, too.
Cheers,
Bill

If the PDF is a form fillable PDF, which I assume that it is, email it to yourself or send it to DropBox and open it on your computer. You should see the fields filled in there. It works for me if I do it that way.
Adobe Reader supports it, but the other apps don't. I assume that if you email the PDF to a computer user it would be readable in Adode Reader.

How to create table in interactive form via Java Web Dynpro

Hi,
How to create table in interactive form via Java Web Dynpro ?
Any online tutorial / example ?
Thank you.
Regards,
Eric

Hi Eric,
Just choose the UI element Table from Form Library and drag and drop it on the form. now choose the no. of rows and columns and other settings you want about table from the wizard initiated through this process. This all is what you have to do to create the table. Now to bind it to the fields of the data source bind the individual colums to individual attributes of the node in the datasource.
Hope it will solve your query.

Error when converting form to XML

I get this error when trying to convert a form using this method:

The WARNING: Item CURR_CODE - all ListItemElements must have an Index, Name and Value. is obvious. It a list is empty this warning is thrown out. Of course my concern is when we do the XML to Forms conversion later will the list item and associated code be reconstructed correctly?
As for the 3 OK buttons and the INACTIVECUSTOMER button the converter puts a DataType attribute, which is meaningless to a button.
I tried to find any peculiarities with the buttons but could not find any.
Has anybody else experienced this problem?

Hi,
I have got the same warning “ all ListItemElements must have an Index, Name and Value” when converting form from fmb to xml using frmf2xml.
Have you find any course of this and how to fix it?
Thanks!
