Calling fonction with parameter in jsp

Hi!
I am looking to call a function of my bean class into my jsp page. But this function has 1 parameter. I want to display the list that this function returns.
For example:
- Bean class: Users
- Bean class: X
- in this class X I have the function: getHobbies(username)
- in my jsp page I get all users nodes and I want to display each user with the list of his hobbies thanks to this function getHobbies, please would you mind telling me if it is possible? I was thinking of something like this:
<a:richList id="users-list" binding="#{UsersBean.usersRichList}"
viewMode="details" pageSize="10"
styleClass="recordSet" headerStyleClass="recordSetHeader"
rowStyleClass="recordSetRow" altRowStyleClass="recordSetRowAlt" width="100%"
value="#{Users.users}" var="b" initialSortColumn="userName"
initialSortDescending="true">
<h:selectOneMenu id="hobbies" style="width:150px" >
<f:selectItems actionListener="#{X.getHobbies(b.username}" />
</h:selectOneMenu>
Thanks

Calling report with parameter form using frmrwinteg

Hi,
I am calling a report with a parameter screen from a form and am using the frmrwinteg bean. This works fine on our test application server but, when moved onto our production application server, the database logon screen is presented after pressing the submit button on the parameter screen. The cause of the problem seems to be the html generated to simulate the parameter screen. The html on the test application server contains a BASE tag in the HEAD section with an href starting "http:/servername.companyname.com". However, the same tag in the html generated on the production application server is missing the ".companyname.com", causing the cookie produced by the frmrwinteg bean to not be found. Does anyone know how the BASE href tag is generated and what I need to change to get the correct BASE href value? I am using Forms/Reports 10g R2 and Application Server 10.1.2.
Cheers....

Problem calling Procedure with parameter from Dynamic Page

I received an error saying the Page not found
here's how to reproduce the error.
1. Create procedure in portal30 schema.
Create or Replace PROCEDURE PORTAL30.ADD_TWO_VALUES
v_one IN NUMBER,
v_two IN NUMBER,
v_result OUT NUMBER)
as
begin
v_result :=v_one+v_two;
end;
2. Create Dynamic Page with following code
<ORACLE>DECLARE
v_total NUMBER;
BEGIN
ADD_TWO_VALUES(:v_one,:v_two, v_total);
htp.p('The total is => ');
htp.p('<input type="TEXT" VALUE='||v_total||'>');
htp.para;
htp.anchor('http://<machine.domain:port#>/pls/portal30/PORTAL30.DYN_
ADD_TWO_VALUES.show_parms', 'Re-Execute Procedure');
END;</ORACLE>
3. I clicked on Customize Link and entered 2 numbers as values for v_one and v_two.
4. Got "The page cannot be found" error in I.E. or "The requested URL /pls/portal30/PORTAL30.DYN_SAMPLE_ADD.show was not found on this server." on Netscape
However when I subsitute "ADD_TWO_VALUES(:v_one,:v_two, v_total);" in the dynamic page for "ADD_TWO_VALUES(3,2, v_total);", it runs just fine.
What's wrong here? Can I not use a parameter from a dynamic page and call a procedure with it? Help is needed urgently and will be greatly appreciated.

Hi,
I tried with your code with few changes ,please try with them.
Create or Replace PROCEDURE <myschema>.ADD_TWO_VALUES
v_one IN NUMBER,
v_two IN NUMBER,
v_result OUT NUMBER)
as
begin
v_result :=v_one+v_two;
end;
I created the procedure in <mySchema> and granted that to <application_schema> and made some changes
<ORACLE>
DECLARE
v_total NUMBER;
BEGIN
<procedure_schema>.ADD_TWO_VALUES(:v_one,:v_two, v_total);
htp.p('The total is => ');
htp.p('<input type="TEXT" VALUE='||v_total||'>');
htp.para;
htp.anchor('http://<your_host>/pls/<portal_schema>/<application_schema>.DYN_FOR_OTN.SHOW_PARMS', 'Re-Execute Procedure');
END;
</ORACLE>
Hope this helps.

Stored Procedure in access with parameter name

Hi, i'm new in JDBC.
I came from Ado.Net.
I want to call a stored procedure in access and set my parameters by name and not by index.
When i try to call the SP with params by index it works as expected,
but with param names it give me this exception:
java.lang.UnsupportedOperationException
Is there a way to call SP with parameter names?
BogN,

Well, it still doesn't work. Here is part of the code, have a look please.

How to assign java script variable to a hidden parameter in JSP?

Hi All,
I want to assign the variable in the Jscript to a hidden parameter in JSP page.
<select name="sortingOption" class="sortingOptions" onchange="changeSortOption(this)">
<c:forEach var="sortingOption" items="${sortingOptionList}">
<c:set var="sortingOptionValue" value="${sortingOption}" target="java.lang.String"/>
<c:choose>
<c:when test="${sortingOptionValue == sortingOptionValueFromRequest}">
<option value="${sortingOptionValue}" selected="selected">${sortingOptionValue}</option>
<input type="hidden" name="srchType" value="none"/>
</c:when>
<c:otherwise>
<option value="${sortingOptionValue}">${sortingOptionValue}</option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>
In changeSortOption script,they capture the value selected by the user and then they submit the form.I want to assign that value to a hidden parameter in JSP,can someone tell me how to do that?
I dont have the Jscript code with me right now to post here.

To the point: just by accessing/manipulating the HTML DOM using JS. Learn JS and HTML DOM. There are basic tutorials at w3schools.com. Besides, your code syntax is still invalid. The input hidden elemend doesn't belong in a select element. Learn HTML. There's a basic tutorial at w3schools.com as well.
For future HTML/JS problems please consult the appropriate forums. This has not much to do with JSP. There are ones at webdeveloper.com.

Could you please confirm and fix,

This is a guess, but I suspect that ords_services.add_parameter() is not required at all.
Also, your URL /demo_product_info/10/ should not have the trailing slash (according to your template URI).
For more information, I suggest you look here:
ords.3.0.0.343.07.58.zip\ords.war\scripts\migrate\core\ords_migrate.plb
The migration package will show what is usually done for templates that already exist within APEX 4.2. I checked my templates and the ones with URI variables {in-curly-brackets} contain no records in apex_040200.wwv_flow_rt$parameters.

How to run a webdynpro multiple times by passing different parameters each time and save webpages with parameter name?

Hi Experts,
I am a BW consultant and new to webdynpro. Not sure how to run RSO_METADATA_REPOSITORY multiple times and by passing different parameter values each time(either taken from an a standard BW table or user provided - anything is fine) and build web pages with parameter name. Need help with direction on where to start.
Let me step back and explain my requirement:
In BW we have an object called transformation.
One way of generating documentation for transformation is highlight transformation and press F1. Then its documentation will be opened as a local web page.
I need these web pages for all transformations. This is my requirment.
I came to know that RSO_METADATA_REPOSITORY is beeing used to generate this web page.
The web link is something like below:
http://ubw05.xxx.com:8005/SAP/BW/DOC/METADATA/?page=BW_O_D&SystemID=BWPCLNT100&ClassID=TRFN&ID=0KHR6J65AIIUTCJZEC093K6XDFV909PB&objectVersion=A&sap-language=EN&sap-client=100
When i run this link seperately(not by selecting transformation and pressing F1) i need to enter login credentials to BW system.
My challenges is how do i pass login credentials and multiple transformation IDs to generate multipe web pages with each page named by transformation ID?
WHere to start? First of all is RSO_METADATA_REPOSITORY Webdynpro JAVA or webdynpro ABAP or can i use anything?
Since it is beeing opened as local webpages i assume it is webdynpro JAVa is that correct?
Thanks,
Raghu
