ME12 - get Charasteristic value from Class maintained
Hi Folks,
In transaction ME12 Vendor-Material wise info-record is maintained in which Class is defined and it has Charasteristics in it.
Now some value is entered in this Charasteristics, so need to fetch this value to display in Purchase Order report.
In my report i am having Material Number and Vendor number.
So, Please all ABAP-Geeks, guide me to get some FM or BAPI or through TABLES to get this details.
Thanks a ton in advance...
Thanks Gautam for prompt reply...
but it didn't helped me in fetching data,, as i m having Vendor number, Material number and Class Type, and my be i can hardcode PIR_VENDOR_DESC and Characteristic.

How to get multiple values from the list
I've a list of an item which I queried it from the database. I also created a button that will takes a selected items from the list when it was clicked. I used javabean to get the data from database.
<% // clicked on Select District Button
Vector vselectedDistrict = new Vector();
Vector vdistrictID = new Vector();
String tmpSelectDistrict = "";
tmpSelectDistrict = request.getParameter("bSelectDistrict");
if(tmpSelectDistrict != null)
// get multiple values from the list
String[] selectedDistrict = request.getParameterValues("usrTDistrict");
vselectedDistrict.clear();
vdistrictID.clear();
if((selectedDistrict != null) && (selectedDistrict.length != 0))
for(int i=0;i<selectedDistrict.length;i++)
vselectedDistrict.addElement(selectedDistrict);
vdistrictID = dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
for(int i=0;i<vdistrictID.size();i++)
out.println("district = " + selectedDistrict[i]); out.println("district ID= " + vdistrictID.get(i).toString());
%>
// get vdistrict from the database here......
<select name="usrTDistrict" size="5" multiple>
<% for(int i = 0; i< vdistrict.size(); i++)
%>
<option value="<%=vdistrict.get(i).toString()%>"><%=vdistrict.get(i).toString()%></option>
<%
%>
</select>
<input type="submit" name="bSelectDistrict" value="Select District">
Lets say the item that i selected from the list is 'Xplace' and I clicked on the Select District button,
what I got is this error message:
org.apache.jasper.JasperException: Unable to convert string 'Xplace' to class java.util.Vector for attribute usrTDistrict: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
So where is going wrong and what the message means?. Any help very much appreciated. ThanksThese are just guesses that might hopefully steer you in directions you haven't looked in yet.
I presume you used triangle brackets (< >) to avoid having the Jive Forum think it was the "italics" tag?
Are you certain this: dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
expects a Vector as its second parameter? And returns a Vector?
I don't believe you've shown how you use the javabean, or its code? Perhaps it should be rewritten to accept an array of strings instead of a Vector? -
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!
Enclosed please find the source code of SubCheckout.java and VNumber.java

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.

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"/>
<!-- Submitting the Form onKeyUp of EmpId field and trying to save the
state of the Form in the scope of session -->
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 bean which stores the properties of all the Form elements -->
<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">
<!-- On successful call of DB the Page has to be forwarded to the same page again by
uploading updated form bean values. -->
<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. -
How to get argument value from portal desktop URL
hi,guys
I have a question ,it is how to get argument value.see:
in one portal desktop,I have a hyperlink like this
http://localhost:7001/TestPortal/appmanager/testPortal/testDST?eventId=1
after click,then will be switch another desktop "testDST"
I tried to get value from request,but failure.
@RequestMapping
public String listTestList(RenderRequest request, RenderResponse response,ModelMap model) {
//HttpServletRequest httpRequest = (HttpServletRequest) ; //request.getAttribute("javax.portlet.portletc.httpServletRequest");
//log.debug("httprequest eventId>>>" + httpRequest.getParameter("eventId"));
log.debug("render request eventId>>>" + request.getParameter("eventId"));
I can't get this value from request,also tried httpServeltRequest,but httpServletRequest can't get,it is null;
so ,how to get this value,thank you very much.
regards
arisHello,
It is true for JSR168 portlets that you can't just arbitrarily set parameters on a URL and get access to them inside your portlet- you must use the appropriate APIs on the PortletURL class to set parameters that you can retrieve. This is the only portable (standards-compliant) way to implement the functionality you want.
However, for your particular use-case, you can get the URL parameters from the (non-JSR168) HttpServletRequest object. The only reason you are getting a null object for that is because the attribute name is wrong. This should work:
HttpServletRequest httpRequest = (HttpServletRequest)(request.getAttribute("javax.servlet.request"));
String eventId = httpRequest.getParameter("eventId");

Htmlb:get the values from bean n display it in textView
Hi,
I am doing one PDK application using jspdyn page. In jsp page I am using htmlb to display the table. In that I am using one text view element. There I need to get the values from bean class.And display it in a table.
Can anyone help me how can use the textView inside htmlb to retrieve the values from bean.
Thanks & Regards
Vineelahi vineela,
For the textView, in the text value write the code <%=myBean.getStr()%>
where myBean will be your bean class and getStr() is the method in the bean class whcih returns value which needs to be displayed on the screen.
Thanks

Get properties value from a bean
Hello
I just began with JSF and have a problem. I konw how to save and get properties value into/from a bean from/into a jsf page. But how can I get the values from a other java class? I would like to get the properties from the bean A and use them in the class B and write them at the end back into the bean. What would be the easiest way for this?
Thank you for the help!
Best regards, mikeDepending on the scope of your bean (request/session), have a look to the related method (getSessionMap or getRequestMap ) from ExternalContext class (accesible from FacesContext.getCurrentInstance)

How to get the values from popup window to mainwindow
HI all,
I want to get the details from popup window.
i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
now i am able to display popup window with values.How to get the values from popup window now.
I can anybody explain me clearly.
Thanks&Regards
kranthiHi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.
