How to pass attribute values through variables in JSP Custom TagLib

Hi,
Can anybody help me how to pass values through varuables in the jsp custom tag.
i am using JSP custom tag. I am unable to pass attribute values through variables.
<invitation:invdetails invid="<%=invid%>"/> The value is passing as <%=invid%> ,not value of the invid.
But i am getting throuh the fllowing
<invitation:invdetails invid='1' />
Please anybody suggest me how to pass value by using the variable.

Hi,
It sounds like you need to set the <rtexprvalue> tag to true in the TLD for your tag. If you do this the tag will read in the value you are trying to pass to it.

How to pass form value through URL?

I have a page set up so that pressing the submit on a form will execute a certain page. For certain reasons I also have a URL HREF link that performs a different function. I need to get the value of a radio button group (all with the same name) and pass that value through the URL if it is pressed. So if someone clicks on the second radio button in the list which has a value of 2, I need to somehow set that to a variable to pass through a URL link. Each time the user changes the radio button I need to dynamically change the variable too.
Is there any way to do this?

Thanks for the suggestions everyone. Here is what I have so far:
I have a cfInput that binds to the radio buttons so the value of the cfinput changes dynamically.
I have a CFDIV that binds to a separate .cfm page that passes the cfinput through as an argument.
The .cfm is very basic:
<cfoutput>
    <cfif isdefined("url.InputText") AND url.InputText NEQ "">
        <cfset FeedVar = #url.InputText#>
    <cfelse>
    </cfif>
</cfoutput>
This method appears to work and it sets the Feedvar variable to the appropriate value. However on my first page with the cfdiv tag when I try to pass the #FeedVar# variable through a URL it says it is not defined.
Any clue if I am doing something wrong passing the new variable back?
Here is the CFINPUT and CFDIV tags:
<cfinput type="text" name="update_typeURL" bind="{update_type}" bindonload="true" />
<cfdiv bind="URL:setURlVar.cfm?InputText={update_type}" ID="theDiv" bindonload="true" />
Any ideas on how to read the newly set variable?

How to pass row values through OpenDocument Hyperlink

Hi all,
I should pass through an OpenDocument hyperlink the value of a particular row of my report. No problems about the OpenDocument syntax and about the other parameters that come from prompt answers, but I don't know how to pass only the value of that particular row. This value doesn't come from a prompt.
So for example if the column of my report was "Account number" and the 1° row of the column that comes from the query was "123456", I should pass only the account number "123456" to the linked document.
Moreover, I have to create the hyperlink on the "Account number" column.
Hoping having been clear...
Thanks in advance,
Riccardo

Hi Stratos,
Thanks for the reply but I have not understood very well.
I try to explain better my issue, making an example of the problem in Open doc syntax
http://aaaaa.bbbbb.com:8080/OpenDocument/opendoc/openDocument.jsp?iDocID=12345&..............&lsSParam1=()&lsSParam2=()&lsSParam3=()
The problem is in the 3° paramater. This parameter is not a user response variable, it comes from an object projected in the report. The object is a numeric type.
The aim is to pass to the 2° report exactly the content of the cell of the 3° parameter, dinamically (I mean depending on the cell selected by the user).
Thanks.
Regards,
Riccardo

How to pass the value of variable to another java file?

Hi. I have 2 java files (LogonAction.java and PCAction.java). The value of variable(String getrole) depends on the logon user. How can I use this value of variable in PCAction.java? I want to execute a sql statement in PCAction.java which is (String sql="Select * from PP where role"+"='" + getrole + "'") Thanks a lot.
LogonAction.java is below:
package test;
import test.jdbc.util.ConnectionPool;
import java.sql.*
import java.util.*;
import javax.servlet.http.*;
import org.apache.commons.logging.*;
import org.apache.struts.action.*;
import org.apache.struts.util.*;
import org.apache.commons.beanutils.PropertyUtils;
public final class LogonAction extends Action {
private Log log = LogFactory.getLog("org.apache.struts.webapp.Example");
private ConnectionPool pool;
public LogonAction() {
pool = ConnectionPool.getInstance();
public String getrole;
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
Locale locale = getLocale(request);
MessageResources messages = getResources(request);
ActionErrors errors = new ActionErrors();
String username = (String)PropertyUtils.getSimpleProperty(form, "username");
String password = (String)PropertyUtils.getSimpleProperty(form, "password");
String getusername=CheckUser(username,password);
getrole=getusername;
java.lang.System.out.println(getrole);
if ("".equals(getusername))
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError("error.password.mismatch"));
getusername=username+getusername;
// Report any errors we have discovered back to the original form
if (!errors.isEmpty()) {
saveErrors(request, errors);
return (mapping.getInputForward());
// Save our logged-in user in the session
HttpSession session = request.getSession();
session.setAttribute(Constants.USER_KEY, getusername);
if (log.isDebugEnabled()) {
log.debug("LogonAction: User '" + username +
"' logged on in session " + session.getId());
// Remove the obsolete form bean
if (mapping.getAttribute() != null) {
if ("request".equals(mapping.getScope()))
request.removeAttribute(mapping.getAttribute());
else
session.removeAttribute(mapping.getAttribute());
// Forward control to the specified success URI
return (mapping.findForward("success"));
* Look up the user, throwing an exception to simulate business logic
* rule exceptions.
* @param database Database in which to look up the user
* @param username Username specified on the logon form
* @exception ModuleException if a business logic rule is violated
public String CheckUser(String username,String password){
Connection con = null;
try
con = pool.getConnection();
String sql = "SELECT * from user WHERE userid = ? AND password= ?";
PreparedStatement ps = null;
ResultSet rs = null;
try {
if (con.isClosed()) {
throw new IllegalStateException("error.con.isClosed");
ps = con.prepareStatement(sql);
ps.setString(1,username);
ps.setString(2,password);
rs = ps.executeQuery();
String returnstr="";
while(rs.next())
returnstr=rs.getString("role");
java.lang.System.out.println(returnstr);
return returnstr;
} catch (SQLException e) {
e.printStackTrace();
throw new RuntimeException("error.ps.executeQuery");
} finally {
try {
if (ps != null)
ps.close();
if (rs != null)
rs.close();
} catch (SQLException e) {
e.printStackTrace();
throw new RuntimeException("error.rs.close");
catch (SQLException e)
e.printStackTrace();
throw new RuntimeException("Unable to get connection.");
finally
try
if (con != null)
con.close();
catch (SQLException e)
throw new RuntimeException(e.getMessage());
}

You can use PreparedStatement and
String cmd = "select * from PP where role=?";
PreparedStatement stmt = conn.prepareStatement(cmd);
stmt.setString(1,theRole);

To pass the values through variable in JDBC adapter

Hello,
We are working in JDBC adapter. Currently we have written the select statement in JDBC sender adapter to select all the values from the table in SQL SERVER.
Instead of this, Can we use a variable and pass the values in there from XI in order to select the records from the table based on values in the variable?
Expecting Advice!
Thanks,
Lakshmi.

Hi krishnan,
You can use the JDBC receiver adapter to acheive a select using variables. Here you create a canonical XML format(your XSD) based on which the JDBC receiver adapter issues a select and returns you the response. chk this url in help site http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm for the canonical format.
However u lose the flexibility of polling the table at regular tables available with sender adapter. Also you need an event(a message) to trigger this select query execution, since it is a receiver CC config.

please replay me soon
thank you.

javascript and java do not mix.
Java code runs, and produces HTML/javascript.
Java code stops running.
The page loads in the browser, and it starts up javascript.
Javascript cannot talk to java and vice versa.
Your JSP can generate javascript code onto the page to be executed on the client, but they never directly communicate.
please replay me soongame over dude ;-)

How to pass attribute values after ExecuteWithParam to method call

Hi,
I am using Jdev 11.1.1.6.
My use case is that I have mainPage BTF which has ExecuteWithParam as the default activity. This filters the VO using params. I have a requirement to store some of the attributes from current row to pageFlowScope which needs to be passed to multiple child taskflows.
I can introduce a method call after ExecuteWithParam activity and before the page renders but not sure how should I pass the current row (or something) to this method call to store the values on pageFlowScope.
What should I pass to this managed bean to store the values on pageFlowScope? Is there any alternative?
Thanks,
Jai

I see two possible ways to get to the attributes. First you can get the iterator current row and get the attributes from there. Second you add attribute bindings to the methods pageDef file for all attributes you are interested in. Then you access them using the attribute binding. I never tested the 2nd method but I guess the framework will fill the attribute bindings like it does in a normal page.
Sorry, can't give you sample code on this add I'm not in front of a PC.

How to pass Text value/bind variable in Export CSV (FLOW_EXCEL_OUTPUT)

I am using the following in Report Definition -> Header
<tr>
<td>
Download
</td>
</tr>
This will give me the standard output in Excel and it will contain columns only specified in SQL query.
I want to import all other bind variables, which I am using in the report (these are not the columns in SQL query). These variables I want to display only once at the top of the Excel.
thanks,

You can create a csv file manually. See this posting:

Pass a Value to Variable from the unix environment in ODI (ELT)

Work Around !
You can execute OS commands using Jython script. Probably you need to flush your enviornment variables value into a file using jython script and then read those value into ODI variable from the file.
BUt may I know why you want to read environment variable vaules in ODI, Dont you think this will make your application less portable

How to pass a value to a bind variable in a query report in oracle apex

Hi Guys,
I have requirement to send weekly reports via email to some users. The users should receive their own records in the report. The user details is stored in a table. What I am planning to do is to create a report query in oracle apex to generate the report and then run a function/procedure via a scheduler to email the report to respective users. Now my query is ............. is it possible to pass a value (user name) to the report query to pull records of only that user? I know we can have bind variables in the report query but I have no idea how to pass a value for bind variables from a function/procedure.
Can anyone help me on this issue or suggest a better approach?
Thanks,

How to pass a value from the report to a form ( BIT OF URGENT ).

Hi,
I had created a "Form on a Table with Report" on the report I had remove the edit link and set one of the column feilds that functionality. Now I want to know how to pass that value that is clicked ( having hyper link ) on to the form where it runs a SQL query and then displays the reuslts on the form.
Illustrating with an example.
I am having these following columns on the report ( these are the results for the join statement )
JOBNUM JOBNAME DEPTNUMBER SAL EMPNO LNAME FNAME
In the above JOBNUM is having Hyper link as I removed the edit image.
Now this is area I am having problem. When the user clicked on the JOBNUM then on form it should display 20 other columns( pulled from 5 other tables ) which are related to that particualr JOBNUM.
Anybody give me a solution in which area I have to include my SQL statement and how to pass that selected value to that SQL statement.
Cheers,
Krishna

Hi Ron,
I am doing exaclty what you have suggested me but no luck. I started changing the DEMO_CUSTOMERS application to my requirements.The report is working fine and on the report I have created a page attribute to the Hyper linked column and linked that to the page 2 and assign that attribute with #JOBNUM#.
I am able to pass that value on to form when I click on the JOBNUM. But the problem is I am not able to pass that value into the SQL query so that my query pulls 20+ columns on to the Form ( which is second page ).
Small clarification... On the form region it is said FORM NAME and type is HTML is that is the way the APEX was designed or does it need to say region type as FORM.
Thanks for your help in advance.
Cheers,
Krishna.

In BADi , How to pass the values between two Method

Hi Experts,
We have two methods in BADis. How to pass the value between two Methods. Can you guys explain me out with one example...
Thanks & Regards,
Sivakumar S

Hi Sivakumar!
Create a function group.
Define global data (there is a similiar menu point to jump to the top include).
Create one or two function modules, with which you can read and write the global data.
In your BADI methods you can access the global data with help of your function modules. It will stay in memory through the whole transaction.

In Jsp TagLib how can I get the Attribute value (like JavaBean) in jsp

Dear Friends,
TagLib how can I get the Attribute value (like JavaBean) in jsp .
I do this thing.
public void setPageContext(PageContext p) {
          pc = p;
pc.setAttribute("id", new String("1") );
          pc.setAttribute("first_name",new String("Siddharth")); //,pc.SESSION_SCOPE);
          pc.setAttribute("last_name", new String("singh"));
but in Jsp
<td>
<%=pageContext.getAttribute("first_name"); %>
cause null is returing.
Pls HELP me
with regards
Siddharth Singh

First, there is no need to pass in the page context to the tag. It already is present. How you get to it depends on what type of tag:
Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/SimpleTagSupport.html]SimpleTagSupport
public class MyTag extends SimpleTagSupport
public void doTag()
    PageContext pc = (PageContext)getJspContext();
    pc.setAttribute("first_name", "Siddharth");
    pc.setAttribute("last_name", "Singh");
    pc.setAttribute("id", "1");
}Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/TagSupport.html]TagSupport or it's subclass [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/BodyTagSupport.html]BodyTagSupport the page context is aleady declared as an implicit object:
public class MyTag extends TagSupport
public void doStartTag()
    pageContext.setAttribute("first_name", "Siddharth");
    pageContext.setAttribute("last_name", "Singh");
    pageContext.setAttribute("id", "1");
}In each case, this sort of thing should work:
<mytags:MyTag />
<%= pageContext.getAttribute("first_name") %>I

How to pass the value from Sub report to main report

I have un report(mainreport) within a subreport(subreport).
With reporting services, how to pass the value from Sub report to main report?
thanks

Hi Alebet,
With reporting services to pass values from sub report in to main report is not supported directly.
But there are some workarounds through which you can get this .
There are two ways to get this.
1- Put your sub report query into some table. i mean to say through the subreport query get some temporary table.
2- Using this temporary tables data write some Scala function in the data base.
3- Now in your main report query return this scala function as a column.
4- Extract the column value where ever you want in your main report which is getting calculated from the subreport query. so you will be getting the values returned from the subreport in the main report.
This will definitely work fine as i have done some report in this way.
Another way of doing is that
1- prepare another data set with the same query as in sub report in the data tab.
2- then refer this 2nd dataset in your main report .
But better way will be the top one.
Anyway please let me know if you get the solution.
Thanks
Mahasweta
