Record History in R12 HTML Forms

Hi all,
Would greatly appreciate if anyone could shed some light on how I can access the (Help -> Record History) option in some of the HTML versions of the R12 standard forms, e.g. customer / supplier master.
I need this to look at "Created By:" "Creation Date:" "Updated By:", etc.
Thanks in advance,
Fazleth

XML in HTML form parameter

Hi,
I would like insert records into database by HTML form, where one parameter (text field) is XML (which will be - after transforming via XSL - compatible with database schema). Is it possible with insert-request? Have you any ideas?
Thanks in advance,
Tom

Hi,
Could you help me more? I've found only example with parameters as fields. Can I use one parameter (XML) as entire rowset?
Thanks,

Again : HTML-form in report body- error

I want to display a report based on a complex view, but I want to make each record updateable via an HTML-form. I added to the view a column which generates HTML, but when I change the combobox, I get an error in the status-bar of the browser "Object doesn't support this property or method."
The submit-action (do_update) is a PL/SQL procedure.
example-record :
Customer oriented <form name="theForm" action="do_update"><input type=hidden value="393" name="p_pmei_id"><select NAME="p_pmei_score" size="1" ONCHANGE="javascript:document.theForm.submit()"><option value="A">A</option><option value="B">B</option><option value="C">C</option><option value="D">D</option><option value="">--</option></select></form>
Quality-minded <form name="theForm" action="do_update"><input type=hidden value="394" name="p_pmei_id"><select NAME="p_pmei_score" size="1" ONCHANGE="javascript:document.theForm.submit()"><option value="A">A</option><option value="B">B</option><option value="C">C</option><option value="D">D</option><option value="">--</option></select></form>
null

The problem is solved ! I used the same form_name for each record, wich caused the error.

Reading html data & uploading a file in single html form using htp package

Hi
I have designed a html screen using htp package in which i have few text items and file upload button. I have to validate all forms data like text items and check box elements and upload file to unix. I am using java script for file validations and cgi script to upload file.

How to enable record history for custom forms

Hi All,
I have developed a custom form but i am unable to view the record history when queried and it throws an error saying 'Record history not available here'.
can some one help me in sorting out the problem.
Thank you

Hi,
The following table lists the standard columns used for Record History (WHO), the column attributes and descriptions, and the sources for the values of those columns. Set the CREATED_BY and CREATION_DATE columns only when you insert a row (using FND_STANDARD.SET_WHO for a form).
CREATION_DATE
CREATED_BY
LAST_UPDATE_DATE
LAST_UPDATED_BY
LAST_UPDATE_LOGIN
For more details, please refer to "Oracle Applications Developer's Guide", Page 3-2 Tracking Data Changes with Record History (WHO)

Need some more fields displayed in record history of oracle forms

Hi ,
I am using oracle forms 6.0.8.8.0 . My requirement is to display PROGRAM_ID , PROGRAM_APPLICATION_ID , PROGRAM_UPDATE_DATE , REQUEST_ID in the record history of the forms along with CREATION DATE , CREATED BY , LAST UPDATE DATE , LAST UPDATE LOGIN , TABLE which are already being displayed .
Please help .

Actually when the record history is to be brought , we need to make it database fields or write code to post query . So I think I can get a solution in this forum as we need to make changes in form only in order to show in record history .

How to submit a html form using java

hi friends,
i have a html form with some input fields, when ever a user submit the form the user information is stored in the database. is it possible to pass the user information in the url(url rewriting) and submit it by a java program so that the data will be stored in the database, as like as, user submit it manually.
for eg:
/*sample.html*/
<form action="store.jsp" method="post">
User Data:<input type="text" name="userdata">
<input type="submit">
</form>
in my java is it possible to store the record as below:
URL url=new URL("http://localhost:7001/webapp/store.jsp?userdata=AutomaticDatasave");
URLConnection con=url.openConnection();
int i=0;
while((i=con.getInputStream().read())!=-1)
System.out.print(i);/*it has to print the data that store.jsp is returned like information stored or error storing data(what ever)*/

hi Drclap,
Thanks for your reply, which is helpful to me....
tried what you said, what i did is modified the code like below
con.setDoOutput(true);
BufferedWriter br=new BufferedWriter(new InputStreamWriter(con.getOutputStream()));
String str="userdata=AutomateDataSave\n";
br.write(str,0,str.length());
br.flush()But
Iam Getting Internal Server Error

How to retrieve data from the HTML form in the JEditorPane?

I could quite easily use JEditorPane to render and display a simple HTML file.
My HTML looks like this:
<html>
<head>
<title> simple form</title>
</head>
<body bgcolor="cccccc">
<center><h1>SURVEY THING</h1>
</center>
<form id="survey">
<p>1.Type something in.</p>
<textarea cols=25 rows=8>
</textarea>
<BR>
<p>2.Pick ONLY one.</p>
<input type="radio" name="thing" value="0" Checked> NO choice <BR>
<input type="radio" name="thing" value="1"> First choice <BR>
<input type="radio" name="thing" value="2"> Second choice
<BR>
<p>3.Pick all you like.</p>
<input type="checkbox" name="stuff" value="A"> A <BR>
<input type="checkbox" name="stuff" value="B"> B <BR>
<input type="checkbox" name="stuff" value="C"> C <BR>
<input type="submit" value="give data">
<input type="reset" value="do clensing">
</form>
</body>
</html>
It gets diplayed fine and I can type in text, select radio buttons (they behave mutualy-exclusive,
as they should) and check checkboxes.
The problem I have is with retrieving the values which were entered into the form.
If I, after editing, try to write the html to the file using HTMLWriter,
it records the changes I made into the textarea, however all the radio and checkbox selections are lost.
Maybe the problem is that when I enter the values I do not use any methods like
insertBeforeStart and so on, but I believe I shouldn't need to use them to populate a form.
Especially I never change the structure of the HTML.
Also, when I try to traverse the Element tree and see the input elements attributes,
I can never see a change in the entered values. However it is probably b/c I am traversing through
the model and the changes are in the view (just a guess.)
Anyway, if anybody could direct me onto the right path: how to retrieve the values typed in the form,
or if it is possible at all in the JEditorPane, I would greatly appreciate.
thanks
maciej
PS. I have seen the answer to a similar question posted some time last year. However, I am trying
to find a soultion which allows forms/surveys to be built by people who have no java and only basic
html knwledge. And Axualize way is probably a little bit too "high-tech."

Maybe helpful for u.

In portlets, how to use a html form passing values to the another page?

it is well known that in web developing , we have two methods to pass values to another page.
but how to use two methods in oracle portal portlets?
I have got a simple example which submit two values to the page for itself, means a page has a form with submit botton, user input the form with values and then submit them by submit botton, then the page recevice those values and show it .
this example is powered by oracle ,
please have a look at these code:

Hi Moonsoft,
I have already answered this query in the other post at Re: how to link more than one links in portlet?(jsp develop)
<form name = "showPageForm" method = "POST" action = "<%= UrlUtils.htmlFormActionLink(pReq,UrlUtils.PAGE_LINK) %>">
<%= UrlUtils.htmlFormHiddenFields(pReq,UrlUtils.PAGE_LINK, "showPageForm") %>
<input type="text" name="param1">
<input type="text" name="param2">
<input type="hidden" name="myPPN" value="/htdocs/page2.jsp">
</form>then in your jsp code on page2.jsp, you will extract the parameters by specifying
<%
String p1 = request.getParameter("param1");
String p2 = request.getParameter("param2");
%>
>>this is easy common jsp or asp development, but in oracle is too diffcult!!!!
:-) .. there is a difference between web-applications and portlets, you just need to get used to it once. I hope this does clarify your doubts.
thanks,

How to use an html form to search my database??

Hey guys,
I'm going through 100's of tutorials on creating a PHP CMS structure for my website and did manage to build a very simple 1. I have 1 question that i need your help with. I was browsing through websites on Google and discovered this website that you can search their data base with a an html form. How can I achieve this in the most simplest ways.
Site URL: http://www.istructe.org/yearbook/index.asp

The form's data is submitted to a php script. The script harvests the data and formulates a SQL select statement -
SELECT * FROM TABLE WHERE fieldname1 = fieldvalue1 AND fieldname2 = fieldvalue2....
(the form's fields are used to build the WHERE part of the statement)
After executing the search the script looks at the number of records found. If that is zero, there were no matches. If there is 1 or more records found, each is printed to the page. You would need some facility with a server scripting language to do this, although not too much. It's fairly simple.

How to reference html form element in javascript ?

Dear all,
My DPK portlet is like this:
I created a html form within it there a several textfields, a hidden field and a SUBMIT button.
The application will call itself to insert a new record to database table on pressing the SUBMIT button.
My problem is that since all the form textfields and the hidden field ara all the qualified names, and I want to set the hidden field to some value, say "ADD" on the onsubmit event in the form. How can I reference the hidden field in javascript ?
Or can you suggest another strategy to do that ?
Many thanks

Here are the code fragment:
String portletParamSubmit = "mSubmit";
String portletParamTitle = "mTitle";
String portletParamURL = "mURL";
String portletParamAction = "mAction";
//Fully qualified URL.
String fSubmit = HttpPortletRendererUtil.portletParameter(request, portletParamSubmit);
String formName = UrlUtils.htmlFormName(pReq, null);
String fTitle = HttpPortletRendererUtil.portletParameter(request, portletParamTitle);
String fURL = HttpPortletRendererUtil.portletParameter(request, portletParamURL);
String fAction = HttpPortletRendererUtil.portletParameter(request, portletParamAction);
String vl_Title = "";
String vl_URL = "";
String vl_Action = "";
String vl_result = "";
if( pReq.getQualifiedParameter(portletParamAction) == "ADD")
vl_Title = pReq.getQualifiedParameter(portletParamTitle);
vl_URL = pReq.getQualifiedParameter(portletParamURL);
//Add News.
try{
CallableStatement cs_2 = conn_erp03.prepareCall("{call XXCT_PORTAL_NEWS_PKG.P_ADD_NEWS(?,?,?,?,?,?)}");
cs_2.setString(1, "ADD");
cs_2.setString(2, pReq.getUser().getName());
cs_2.setString(5, vl_Title);
cs_2.setString(6, vl_URL);
cs_2.registerOutParameter(10,Types.VARCHAR);
cs_2.execute();
vl_result = cs_2.getString(10);
cs_2.close();
catch (SQLException se) {
sb.append("Query: SQL Exception: " + se.toString());
System.out.println(sb);
