Calling a method with parameters in jstl?
i need to call a method with a series of String parameters what am i doing wrong?
the java
public ArrayList getEmployeeSkills(String ename, String snmae, String yearsexp)the jstl
<jsp:useBean id="empskill" class="com.Database.EmployeeSkill"/>
<c:forEach var="emp" items="${empskill.EmployeeSkills(null, null, null)}">
</c:forEach>
this works:
<jsp:useBean id="empskill" class="com.Database.EmployeeSkill" scope="page">
<jsp:setProperty name="empskill" property="ename" value="Helen Smith"/>
<jsp:setProperty name="empskill" property="sname" value="Java"/>
</jsp:useBean>but this part isnt:
<c:forEach var="empskill" items="${empskill.EmployeeSkillsReport}">
</c:forEach>ive removed the get part from the method as i have done before from the java class it is calling:
public ArrayList getEmployeeSkillsReport()
but it produces:
org.apache.jasper.JasperException: Exception in JSP: /main.jsp:146
143: </jsp:useBean>
144:
145:
146: <c:forEach var="empskill" items="${empskill.EmployeeSkillsReport}">

How to call a AM method with parameters from Managed Bean?
Hi Everyone,
I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
Class[] paramTypes = { };
Object[] params = { } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };
Object[] params = {aVal } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you

Best practice for calling an AM method with parameters
Which will be the best way to call an AM method with parameters from a backing bean.
I usually use the BindingContainer to get the operation binding and then call execute function. But when the method have parameters, how to do it?
ThanksHi,
same:
operationBinding.getParamMap().put("argument1Name", argument1Value);
operationBinding.getParamMap().put("argument2Name", argument2Value);
operationBinding.execute();

For example, if the string variable contains "hellojava" , i'd like the hellojava() method to be called..
if the string contains "error", the error() method should be called..
and so on..:)Here is an example I had thrown together for this
purpose of the exact demonstration, Ar'nt you in luck.:-). If there is anything you don't understand,

FRM-92101 Error by calling the form with parameters

Please help me if anybody has this problem before.
SergeyHi Sergei,
I've just finished a three day search for a FRM-92101problem, so I want to post my case, just in case it helps someone.
My case is similar to yours, in that you have a Forms 6i form migrated to 10g and deployed on Linux, although my problem was "very" specific, and thus very hard to find, this might give you some light.
I had a visual attribute that defined the property "Fill Pattern" as "none" applied to a canvas, and it deployed without any problem on 10gR2/Windows, but when deployed on Linux (10gR2/SUSE 9) it would abort the application getting a FRM-92101.
The solution in this case was just changing "none" to "Transparent".
Hope this helps.

Miguel. -
Call a method with complex data type from a DLL file
Hi,
I have a win32 API with a dll file, and I am trying to call some methods from it in the labview. To do this, I used the import library wizard, and everything is working as expected. The only problem which I have is with a method with complex data type as return type (a vector). According to this link, import library wizard can not import methods with complex data type.
The name of this method is this: const std::vector< BlackfinInterfaces::Count > Counts ()
where Count is a structure defined as below:
struct Count
Count() : countTime(0) {}
std::vector<unsigned long> countLines;
time_t countTime;
It seems that I should manually use the Call Library Function Node. How can I configure parameters for the above method?You cannot configure Call Library Function Node to call this function. LabVIEW has no way to pass a C++ class such as vector to a DLL.

In SQLScript, how to use EXEC to call another procedure with parameters in procedure?
Hi experts,
In SQLScript, How to use EXEC to call another procedure with input and output parameters in procedure?thanks very muchHi Sagar,
thank you! I generate another procedure with an input parameter and an output parameter in a procedure. Then i need to call the generated procedure using EXEC. Here is my code:
create procedure ftest1(out sum_num bigint)
as
begin
declare fa_output bigint;
declare v_sql_drop varchar(200);
declare v_sql varchar(500);
declare cursor c_cursor1 for select num from TABLE1;
--v_sql_drop := 'drop procedure fe';
--exec v_sql_drop;
v_sql := 'create procedure fe(in i_num bigint,out o_num bigint) as begin';
v_sql := :v_sql || ' o_num := :i_num * 2 + :i_num * :i_num;';
v_sql := :v_sql || ' end';
exec v_sql;
open c_cursor1;
for c_item as c_cursor1 do
exec 'call fe(c_item.num,o_num=>fa_output)';
if sum_num is null then
sum_num := fa_output;
else
sum_num := :sum_num + fa_output;
end if;
end for;
close c_cursor1;
end;
The underline code is using exec to call the generated procedure. But this method cannot work. Any suggestion? thanks again! -
Dynamic Imagelink Component - Calling Impl method with input parameter
Hi All,
I have requirement where Imagelinks are created dynamically on the pageload. Generated the components and the components are displayed on the jspx.
Now when I click the image link, a method in AMImpl should invoke and this method takes some input parameters.
I am able to call the method successfully in AMimpl with the help of below code. But I could not understand how to pass the input parameters to that method.
RichCommandImageLink lockimageLink =
new RichCommandImageLink();
lockimageLink.setIcon("icon.png");
lockimageLink.setId("icon" + index);
MethodExpression me =
JSFUtils.getMethodExpression("#{bindings." +
"MyMethodName" +
".execute}");
lockimageLink.addActionListener(new MethodExpressionActionListener(me));
public static MethodExpression getMethodExpression(String name) {
Class [] argtypes = new Class[1];
argtypes[0] = ActionEvent.class;
FacesContext facesCtx = FacesContext.getCurrentInstance();
Application app = facesCtx.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesCtx.getELContext();
return elFactory.createMethodExpression(elContext,name,null,argtypes);
} Can some one please suggest how to pass input parameters to the Impl method.
Jdeveloper Version : 11.1.1.4.0
Thanks,
Morgan.
Edited by: 900114 on May 12, 2012 11:23 PMYou can use the below method to call an AMImpl method. You can pass parameters as well to the AMImpl method.
DCBindingContainer bindings = getDCBindingContainer();
OperationBinding ob = bc.getOperationBinding("MyMethodName");
Map m = ob.getParamsMap();
ob.put("paramName", "paramValue"); paramName is the parameter in AMImpl and paramValue is the value to be passed.
ob.execute();
Where getDCBindingContainer() is:
public DCBindingContainer getDCBindingContainer() {
ExpressionFactory exprFactory;
ELContext elContext;
ValueExpression valueExpression;
DCBindingContainer dcBindingContainer;
FacesContext facesContext = FacesContext.getCurrentInstance();
exprFactory = facesContext.getApplication().getExpressionFactory();
elContext = facesContext.getELContext();
valueExpression =
exprFactory.createValueExpression(elContext, "#{bindings}",
Object.class);
dcBindingContainer =
(DCBindingContainer)valueExpression.getValue(elContext);
return dcBindingContainer;
Hope this helps

Calling stored procedures with parameters with the Database Connectivi​ty Toolkit
Hi all,
I am new to the forum and am having difficulty finding a solution to a particular problem I am having regarding using the LabVIEW Database Connectivity Toolkit on a project I am currently working on at my job. I have a database in which I have tables and stored procedures with parameters. Some of these stored procedures have input, output, and return parameters.
I have been trying to follow this example but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument
One such stored procedure I am working on implementing is named "dbo.getAllowablePNs", which executes "SELECT * from DeviceType" (DeviceType is the table). In this case, it does not require an input parameter, it has an output parameter that generates the table [cluster], and has a return parameter which returns an integer value (execution status code) to show if an error occurred. The DeviceType table has 3 columns; ID (PK, int, not null), PN (nvarchar(15), null), and NumMACAddresses (int, null). I have gone over many examples and have talking to NI support to try to implement this and similar stored procedures in LabVIEW but have not been successful. I am able to connect to the database with the Open Connection VI without error, but am running into some confusion following this step. I am then trying to use the Create Parameterized Query VI to call the stored procedure and set the parameters. I assume I would then use the Set Parameter Value VI for each parameter that is wired into the parameters input on the previous Parameterized Query VI? I am also having some confusion during and following these steps as well. I would greatly appreciate any advice or suggestions anyone might have in regards to this situation as I am not a SQL expert. Also, I would be happy to provide any more information that would be helpful.
Regards,
Jon
Solved!
Go to Solution.Also, I don't know if this would be helpful but here is the actual stored procedure in SQL:
CREATEPROCEDURE [dbo].[getLastSequenceNumber]
@p1 nvarchar(10)='WO-00000'
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SETNOCOUNTON;
-- Insert statements for procedure here

Calling Stored procedure with Parameters in PowerPivot DataModel
Hi All,
I wanted to call a SQL stored procedure from PowerPivot(Excel) on based on changing slicer's value.
Currently, we can call stored procedure wihtout any parameter from Data Model tab using
Exec stored_proc_name in Table Properties window.
What if I want to call the same procedure with a parameter whouse value will come by changing slicer's value. I meant, changing slicer value will act as a parameter to that stored procedure & it should return updated results.
Is this possible in PowerPivot?Hi Rameshwar,
According to your description, you call a SQL Server stored procedure in PowerPivot data model, now the problem is that you need to pass a parameter to the stored procedure, right?
Based on my research, it seems that we cannot achieve this requirement directly in current version of PowerPivot data model. Here is a similar thread for you reference.
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/5350228d-bc62-4a3b-a1a6-e847483e2858/powerpivot-for-excel-2013-call-execute-stored-procedure-with-parameters?forum=sqlkjpowerpivotforexcel
If you have any concern about this behavior, you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is resolved in the next release of service pack or product. Your feedback enables Microsoft to make software and services the best that they can be, Microsoft might consider to add this feature
in the following release after official confirmation.

Calling a method with a html Submit button
hi guys,
is it possible to call a method from a JSP file using a HTML submit button. I know i can call another website easily doing it this way, is there a similar way available to call a method once the button is clicked?
FYI
The method is in a bean file named jdbc. The methods name is getUsername.
Nice one.
<form action = <%jdbc.getUsername()%> <input type="submit" value="Submit">Dear friend,
you mentioned that u need to call a method when submit button is clicked. Is the method dynamically created. If not so, then you can include the method on the submit button html file itself.

Using Java Reflection to call a method with int parameter
Hi,
Could someone please tell me how can i use the invoke() of the Method class to call an method wiht int parameter? The invoke() takes an array of Object, but I need to pass in an array of int.
For example I have a setI(int i) in my class.
Class[] INT_PARAMETER_TYPES = new Class[] {Integer.TYPE };
Method method = targetClass.getMethod(methodName, INT_PARAMETER_TYPES);
Object[] args = new Object[] {4}; // won't work, type mismatch
int[] args = new int[] {4}; // won't work, type mismatch
method.invoke(target, args);
thanks for any help.Object[] args = new Object[] {4}; // won't work, type
mismatchShould be:
Object[] args = new Object[] { new Integer(4) };The relevant part of the JavaDoc for Method.invoke(): "If the corresponding formal parameter has a primitive type, an unwrapping conversion is attempted to convert the object value to a value of a primitive type. If this attempt fails, the invocation throws an IllegalArgumentException. "
I suppose you could pass in any Number (eg, Double instead of Integer), but that's just speculation.
