Getting the Type from a DataReader

How do I test for the "Type" when using the DataReader? I'm trying to determine what DataType each field is.
While dr.Read()
If dr.GetType(0).GetTypeCode = OracleDecimal Then
'Do something
Else
'Do something else
End If
End While
Jeff

Actually, I used:
If dr.GetDataTypeName(i).ToString = "Decimal" Then
myVal = dr.GetOracleDecimal(i).ToDouble
Else
myVal = dr.GetValue(i)
End If
Thanks anyway!

How to get the values from struct data type using java code..?

How to get the data from struct data type using java code.
Thanks in Advance.

Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.
Regards,
Dan

NullPointerException - Cannot get the value from variable f_cashGiven

In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!

If getValue() returns null, you need to trace the execution of the code and figure out which sequence of code is leading to the return of null. This method looks complex - a lot of if statements. If you do not have a debugger, put System.out.println statements inside the method to figure out what's going on.

Swing: when trying to get the values from a JTable inside an event handler

Hi,
I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
I put two buttons (plus labels) and a JTextField . The buttons have the following role:
One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
I would thank you very much for the help.

in the row_Selection function
if(ex.getValueIsAdjusting()) //To remove double selection
return;
ListSelectionModel lsm = (ListSelectionModel) ex.getSource();

ResultSetTableModel model = (ResultSetTableModel) players.getModel();
String name = (String) model.getValueAt(selected_row, 1);

This is how I got info out of a table when the user selected it

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>

<form-beans>
<form-bean name="employeeFormBean" type="org.apache.struts.action.DynaActionForm">
   <form-property name="empId" type="java.lang.String"/>
   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.

here i have an list called listOfEnrichProducts.
here i am adding two objects of enrichedProductCatalogue.
which contains a object called BundleProduct.
which has a reference for Product class.
here this product class has a list which contains objects of another class called UiCategory.
the problem here is i am not able to get the data from the list which contains UiCategory objects .
the following is the UI

Unable to get the response from dynamic partnerlink

Hi
I used dynamic partnerlink, in this i am able to invoke the services dynamcially but i am unable to get the response from the services which i had invoked dynamically. In my dynamic partnerlink wsdl i had included callback binding and call back service in the wsdl you can see them below
<binding name="LoanServiceCallbackBinding" type="tns:LoanServiceCallback">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="onResult">
<soap:operation soapAction="onResult" style="document"/>
<input>
<soap:header message="tns:RelatesToHeader" part="RelatesTo" use="literal" required="false"/>

</input>
</operation>
</binding>
<service name="LoanServiceCallbackService">
<port name="LoanServiceCallbackPort" binding="tns:LoanServiceCallbackBinding">
<soap:address location="http://openuri.org"/>
</port>
</service>
please help me on this
thanks
Srikanth

Hi, thanks for the input
Actually My partnerLink had two messageTypes one for Input message request and the other for the Output message request and for the input message i had used the operation as initiate also for the output messsage type operation as result.For both of them binding is defined.
With these am passing the values from myBPELl to the service which am nvoking dynamically but unable to capture the response the variables are local to myBPEL.

Unable to get the value from the textfield in valueChangeEvent

Hi,
I have created one custom textField by extending the CoreInputText. Now i have attched default ValueChangeListener to it. I am using this textField in my application.
Now i type some thing and do a focus lost, the value change listener get called. i want to validate the value entered. In that listener method if i take the getSource() from ValueChnageEvent object and do a getValue() I am getting the entered value.
My problem is that if i do a getValue() of the textField i am not gettting the value entered.
How can i get the entered value from the textfield.? Is there any method to notify to do this?
Thanks in advance.

Hi,
I tried to the value from coreInputText also. If i check the getValue method of the component, i am getting the last updated value. I have debug the FlowPhaseListsner also. And i found that this listener is calling before the updateModel phase. Due to that i am not getting the value from the Field.

Get the Type of a generic field at runtime, How to?

Hello,
As the topic already says, i need to get the Type of a particular field of a class. This field is declared private and generic. In C# there is a method
Type Object.getTypeIs there any specific way to do this in Java 1.5?
Please excuse my poor english.
Thanks in advance.

If you want to know the parametrized type (String in the example), I think there is no way of knowing this in Java 1.5 or Java 1.6, since the parametrized type is erased and not available at run time.The type of a parameterized field is not erased.For most intents and purposes, it is. Type erasure refers to the fact that at runtime, there are not actually multiple class binaries depending on the generic arguments to a class. Therefore, an ArrayList<T> is actually just an ArrayList with no generics.
Frankly, I don't understand why you insist that the information on generic fields that the OP was asking about is lost at runtime.I wasn't trying to insist that. At the time, I was replying more to Saish and trying to reaffirm that most information about generics is lost at run-time. I mistakenly ignored how you qualified it with "field."
What you write about instances of generic classes losing their type information is of course correct, albeit not to the point of the original question.Nope, you're right. I was just trying to reconcile the fact that many people get confused that there's any information available at run-time, and so start down the path of thinking that type erasure doesn't exist. But it very much does.
The original question was about how to obtain the type of a generic field.And I did show in my example that even that is fairly limited, given that if the type is provided by the parameter of the class, it doesn't give you anything useful (I'm not trying to say you said it would!).
The compiler preservers this information in the class file, so it can be obtained at runtime. Frameworks like JPA put this to use extensively, proving that it is of real value.Definitely. However I don't see this having as much to do with generics as basic reflection functionality. If you can get the type of a field at run-time, you should be able to get the parameters as well! That should in no way belittle its value, though. But I would have guessed (knowing little about) that JPA wouldn't put that to use so much as the type parameters of an accessor return type or mutator argument type. Especially since I thought we'd shown that you would need your fields to be non-private for JPA to be able to gain information about their type.
Edit: getDeclaredField works fine with private members, and returns the expected "java.lang.String" from jschell's example above

How to get the type of answer in a workitem?

Hi Experts,
I am building a report to get the users responsible for the approval of SCs and POs, in this report I need to get the type of answer given by the approver, if they have rejected, approved or partial rejected / approved the object.
When I look at the container of the workitem I can get the agent responsible for the action and the dates, but I need your help to determine the type of answer. I believe I can get this information from the approval state, no? But I am getting a lot of different approval states: 0, 1, 3, 4, 10, 11 and 15. Can you provide me some guidance? I am new to workflows and I am stuck in this point.
I am using SRM 5.0 and n-step approval workflow.
Thanks in advance,
Francisco

I'm not an SRM expert, but from a pure workflow point you can read the output of a workitem. So, check how your workflow is built and then see what values are returned in the corresponding return fields. Explore the workitem structure in the log.

How to get the type of numeric

Hi,
I would like to know how getting the type of a numeric data programmatically. (DBL, SDL, I16, I32,etc.)
This property is defined by selecting "Type of data" in the property's window of a numeric data; then by clicking on "representing".
I tried to find the solution by using a property node then accessing to the property called 'representing".
Without success, it seems this function is not available.
Is anyone would know the solution.
Thanks by advance,
pr93

There are several solutions.
The 7.x version of the Flatten To String function had an additional output called "type string" which was actually an array of numbers. This array would tell you that information. OpenG has a VI that will tell you the datatype from this array. It's called "Get TDEnum From TD" and is in the LabVIEW Data Tools library. You can use VI Package Manager to easily install OpenG libraries.
If you have a control you could use a reference and then use the "Get Type of Control" VI from the <vi.lib>\Utility\GetType.llb library.
You could convert th"e numeric value to a variant and then use the "Get Type of Variant" VI from the <vi.lib>\Utility\GetType.llb library.
