how to pass List parameter?

Hi
You should pass your parameter with the <f:attribute> tag.
See this sample:
<af:declarativeComponent id="dcPrj" viewId="/WEB-INF/views/template/project.jsff">
<f:attribute name="dataMap" value="#{backingBeanScope.vlbb.projectData}" />
</af:declarativeComponent>
Where my "projectData" is a HashMap and declared in the fragment as it.
<af:xmlContent>
<component xmlns="http://xmlns.oracle.com/adf/faces/rich/component">
    <display-name>ProjectTemplate</display-name>
    <description>This component will show project info.</description>
    <attribute>
      <attribute-name>dataMap</attribute-name>
      <description>Map with all data required</description>
      <attribute-class>java.util.HashMap</attribute-class>
      <required>true</required>
    </attribute>
</component>
</af:xmlContent>
I hope this solve your problem.

How to pass parameter from SSO login page to ADF application page?

We have ADF-JSF application (running on AS 1013) that is being protected by OID running on AS 1012. SSO login page contains (among others) paramter ssousername and I wish to pass this to my ADF application. For the testing purpose I created ADF application entry point page that has something like this:
<h:outputText value="#{param.ssousername}"/>and my sso login page has:
<input type="text" size="30" maxlength="50" name="ssousername" value="<%=str_user%>">OID and ADF OC4j are running on two different servers, same network.
So after successful login, when my page displays param passed is NULL?!
Why?

I solved it with the following....when my page loads, I execute test method:
    public void processLogin(String ssousername) {
         Object o = JSFUtils.getUserFromSSOLogin();
         if (o!=null) System.out.println(o.toString());
    public static Object getUserFromSSOLogin(){
        FacesContext ctx = FacesContext.getCurrentInstance();
        return ctx.getExternalContext().getRemoteUser();
    }

How to pass parameter between two jsp pages using web link (not form)

Hi Friends,
I have two jsp pages and would like to pass a parameter from one JSP page (one.jsp) to another JPS page (two.jsp)
in one.jsp
<a href="two.jsp?ant="<%=ant%">"> <%=antName%> </a><br>
I don't know how to pass value of parameter "ant" to two.jsp from one.jsp.
Can anyone help this? Thank you in advance</a>

Looks like you've got it almost right - just an extra unneeded "
<a href="two.jsp"?ant=<%= ant %>"><%=antName%></a>
which should render on the page as something like
My Ant Task
When you click the link, it should pass that parameter, and you can get it via request.getParameter().

Pass parameters from JSP Dyn Page to WDJ Application

Hi,
I am trying to pass parameters from my JSPDyn Page to WDJ Application.
I am using NWDS 7.1 EHP1
My code is :
function to_WEBDYNHK()
      EPCM.relaxDocumentDomain();
      EPCM.doNavigate
    ('ROLES://pcd:portal_content/Himanshu.Himanshu/TestDynUIApp?DynamicParameter="hkparam%3Dqwertyuio"');
This method is being called on click of a button.
hkparam is the parameter in question.
The JSPDyn page is an iView and the WDJ application is a page and both have been assigned to a role.
In the properties of the WDJ Page, I have removed DymanicParameter from "Do not Forward These Parameters To Web Dynpro" property.
However I am getting null as the value of hkparam in my WDJ application.
The code used is :
IWDRequest request = WDProtocolAdapter.getProtocolAdapter().getRequestObject();
       String param1= request.getParameter("hkparam");
What seems to be missing here.
Please help.
I went through the documentation on SDN but it does not seem to help.
TIA,
Himanshu

Hi Himanshu,
Try this code.
EPCM.doNavigate("ROLES:portal_content/Himanshu.Himanshu/TestDynUIApp?hkparam=Dmypass1123")
if the parameter is hkparam and the value to be passed is Dmypass1123. You need not change any design time property of the WD page, and WDProtocolAdapter should retrive the parameter.

To get date Parameter from an OAF page

Hi,
I want to get a date parameter from an OAF page and pass them to a query in Vo as binding variables.
How can that be done.

String v_date = pageContext.getParameter("StartDate");

My CO --------------------------

How can I pass parameter from report to form?

Hi :)
Now I try to build conference room like this by using form
and report. And i design that when users click at group report
then i'll show page that contain questions report and add
question form. And question form and report must receive the
same parameter from group report.
First Problem: is I don't know how group report send the
same parameter to question report and add question report at the
same time. And is it possible??? If not please suggest me what
should I do???
Second Problem: is I don't know how can I pass parameter from
report to form. I don't know the way to do it.
Please tell me!!! Please...
I look forward to hearing from all of you.
Thank You.

One way is to create a link based on that form and attach that
link with the report. Through links you can pass parameters

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

How to pass parameter from 1 stored procedure to another stored procedure inside crystal report

Hi
I have several stored procedure in my Crystal Report. I am wondering if it is possible for me to pass a parameter to one of the stored procedure and to use the result of that stored procedure E.g. CustomerCode. To another 2 stored procedure to generate the report dynamically?
I have 3 stored procedure
The 1st one is used to gather information and process the calculation
another 2 stored procedure is used for generate the graph and both of them required to take 2 parameters. The 1st stored procedure will require 1 parameter (E.G. Reference Code) and will return a set of information including the data that could be use on the other 2 stored procedures.
After I added these 2 stored procedure, it requires me to pass 3 parameters to the report. I would like to know if I could only pass the Reference Code for stored procedure 1 and use it to retrieve the information for the other 2 parameter?
Thanks in advance
Chi

Hi Chi
To pass parameter from 1 stored procedure to another stored procedure, you will have to create sub report. In your case you will have to create 2 sub reports for 2nd and 3rd stored procedure and link those sub reports with the main report using Reference Code field in order to pass the values.
After creating the report when you will refresh the report, it will ask 4 parameters, one parameter for main report, one for the first subreport and two for second subreport to fetch the data correctly.

Master-detail relationship - passing parameter from form to form

Hello.
I have a question about master detail relationship.
In first form we have master-detail relationship.
Example on dept, emp tables:
We query dept (master), so we can get one or many emp (detail) records. Then we have a third table - tasks. Tasks table (detail) can have many records for one employee.
Tasks table is in another form, which is called with call_form built_in. So we pass a parameter from master to detail - parameter empno. Because of that, we can only see tasks for one employee and can't navigate to another employee. This is normal.
Now comes the question.
Is it possible to call a form (with tasks table) with deptno parameter (so we can navigate through all employees with that department), but first show employee that was last used in first form?
Example of our goal.
Master: deptno = 20
Detail: navigate to JONES employee
Call new form (tasks)
Tasks for JONES employee are first shown
Can navigate to another employee - without requery
Is this possible?
If we pass deptno parameter, we can navigate through all employees - but must navigate to the employee we last used in first form.
If we pass empno parameter to second form, we see last used employee but cannot navigate to another employee without requery.
Hope you understand my problem.
Thanks.

Hi
yes you can pass parameter from one form to another.
In your master detail form set the trigger when-new-instance and there define the global variable like
:GLOBAL.G_CIRCLE_ID := NULL;
and in your task table set the trigger when-new-instance and there define the global variable like and also write this code
:GLOBAL.G_DIVISION_ID := NULL;
IF :GLOBAL.G_CIRCLE_ID IS NOT NULL THEN
     GO_BLOCK('DIVISION');
     SET_BLOCK_PROPERTY('DIVISION',DEFAULT_WHERE,'CIRCLE_ID ='||''''||:GLOBAL.G_CIRCLE_ID||'''');
     EXECUTE_QUERY;
END IF;
:GLOBAL.G_CIRCLE_ID := NULL;
now you maintain your trigger according your need.

In addition you need to tell us your jdev version!
Can you elaborate on your use case a be more?
On which event this should happen?
In general contextual events should allow you to implement this, however, as I don't understand the use case, I find it hard to help.
