How to retreive and display output list from BAPI
Hello
I am making an applcation using SUP 2.0, and this application make an user to get leave history using a Mobile System from SUP.
I've created the MBO as Attributes using the BAPI: BAPI_LEAVE_HISTORY.
This BAPI has some parameters IN and OUT.
Input parameters are Employee Id and date.
The parameter OUT is a List that retreives the employee leave history.
Anyone has an Idea or example how to retreive the output from BAPI and displaying the output on a screen.
Any tips or blogs that can help me?
Thanks all!
SatishHi David Brandow,
I have tried your solution where I just created a MBO for my 'operation' and I'm using sync parameters to execute the RFC.
The problem I'm facing is, for example, if I create a record it gets saved in the MBO table and the record successfully gets created in SAP as well after a sync. But when I create another record and sync, the previously saved record in MBO table also gets executed so I'm getting duplicate entries in SAP.
Have you or anyone faced this problem?
Any response is appreciated. Please let me know if I'm not clear, I realized its a complicated scenario.
Thanks,

How to catch and display a link content in another portlet page?
Can you tell me how to display a URL content into next page after an user click s on this link? I am developing a JSR 168 portlet under a Portal. I have 3 pages so far in my portlet. view.jsp, view2.jsp and IpByHourPage.jsp. view2.jsp displays a lis of IP address. When an user clicks on an IP in view2.jsp, it goes to IpByHourPage.jsp. How to catch the IP address such as 123.23.89.21 that an user just click displayed in IpByHourPage.jsp. I don't know why I got null value returned.
Also, I don't know how to do a "go back to previous page". I want to go back to view2.jsp from IpbyHourPage.jsp
Here is my code
in view2.jsp
<portlet:renderURL var="aURL">
<portlet:param name="goto" value="IpByHourPage"/>
</portlet:renderURL>
<a href="<%=aURL.toString() %> "><%=MyIP%></a>
in IpByHourPage.jsp
<%
String MyIPHour = request.getParameter("goto");
%>
<h1>IP Report by Hour ( <%=MyIPHour%> )</h1>
<portlet:renderURL var="Ret_IPByHour">
<portlet:param name="Ret_IPHourPage" value="Ret_IPByHourPage"/>
</portlet:renderURL>
<center> <a href="<%=Ret_IPByHour.toString() %> "><b>Choose Another IP</b></a></center>
in my .java file
protected void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException, UnavailableException {
response.setContentType("text/html");
String MyBegDate = request.getParameter("BegDate");
String MyEndDate = request.getParameter("EndDate");
String MyNetworks = request.getParameter("networks");
String MyYourName = request.getParameter("yourname");
PortletURL renderURL = response.createRenderURL();
renderURL.setPortletMode(PortletMode.VIEW);
request.setAttribute("renderURL", renderURL.toString() )
String GotoRenderAction = request.getParameter("goto");
String MyIPHourAction = request.getParameter("Ret_IPHourPage");
if ( (MyIPHourAction!=null) && MyIPHourAction.equals("Ret_IPByHourPage") )
PortletRequestDispatcher kk = getPortletContext().getRequestDispatcher("/view2.jsp");
kk.include(request, response);
if (MyIPHourAction != null && MyIPHourAction.equals("Ret_IPByHourPage"))
PortletRequestDispatcher mm = getPortletContext().getRequestDispatcher("/view2.jsp");
mm.include(request, response);
if (GotoRenderAction != null && GotoRenderAction.equals("IpByHourPage"))
request.setAttribute("BegDate", "MyBegDate");
request.setAttribute("EndDate", "MyEndDate");
System.out.println("BegDate" + MyBegDate);
System.out.println("Endate" + MyEndDate);
PortletRequestDispatcher mm = getPortletContext().getRequestDispatcher("/IpByHourPage.jsp");
mm.include(request, response);
if(MyEndDate!= null )
PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/view2.jsp");
prd.include(request, response);
else if (MyEndDate==null && GotoRenderAction == null)
PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher("/view.jsp");
prd.include(request, response);
The problem for above code is the clicked single IP can not be displayed in IpByHourPage.jsp. and I cannot go back to view2.jsp from IpByHourPage.jsp. when I click "Choose Another IP"
I find out that the MyBegDate and MyEndDate values are all null when I click Choose Another IP link. I got the following error message
Caused by: javax.servlet.ServletException: Unparseable date: "null null"
at org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:858)
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:791)
at org.apache.jsp.view2_jsp._jspService(view2_jsp.java:651)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
How to fix above problems. ThanksI think the problems are related to portletsession. But I don't know how to use it. How to put portletsession into doview method or my jsp pages. Can anyone tell me in my code? Thanks a lot.

Using java class and variables declared in java file in jsp
hi everyone
i m trying to seperate business logic form web layer. i don't know i am doing in a right way or not.
i wanted to access my own java class and its variables in jsp.
for this i created java file like this
package ris;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class NewClass{
public static void main(String args[]){
Connection con = null;
ResultSet rs=null;
Statement smt=null;
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
smt=con.createStatement();
rs= smt.executeQuery("SELECT * FROM emp");
while(rs.next()){
String str = rs.getString("Name");
}catch( Exception e){
String msg="Exception:"+e.getMessage();
}finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}
}next i created a jsp where i want to access String str defined in java class above.

i am using netbeans ide.Very bad approach
1) Think if your table contains more than one NAMEs then you will get only the last one with your code.
2) Your String is declared as local variable in the method.
3) You have not created any object of NewClass nor called the method in JSP page. Then who will call the method to run sql?
4) Your NewClass contains main method which will not work in web application, it's not standalone desktop application so remove main.
Better create an ArrayList and then call the method of NewClass and then store the data into ArrayList and return the ArrayList.
It should look like
{code:java}
package ris;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class NewClass{
public static ArrayList getNames(){
Connection con = null;
ResultSet rs=null;
Statement smt=null;
ArrayList nameList = new ArrayList();
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
smt=con.createStatement();
rs= smt.executeQuery("SELECT * FROM emp");
while(rs.next()){
nameList.add(rs.getString("Name"));
return nameList;
}catch( Exception e){
String msg="Exception:"+e.getMessage();
</code><code class="jive-code jive-java"><font>return nameList;</code><code class="jive-code jive-java">

Problem accessing variables from java file to JSP page

This is my Java file

Thanks KT......How are you declaring the class in your JSP? ... are you instantiating it as a bean using the useBean tag, or just instantiating it in your code like normal.
Maybe you could post the relevant JSP code too?
Hello again,
Only the last string is populating after the file has be tokenized. What I'll like to accomplish is passing the very first string in the file. I did not get too far in the JSP file setup because the code is still in it's testing stage, but any help will be highly appreciated.
Here is the JSP code
<%@page import="dev.*" %>
<%@page session="true" language="java" import="java.io.*" %>
<jsp:useBean id="wagerhist" scope="request" class="dev.RoundDetail2" />
<html>

How to retrieve and display image from database in a web page
Hi all;
I have been trying this for some time now. I have found some tutorials so far but none of them addresses my concern. Here it is:
I have built a web application that can connect to an Oracle DB.
I have a table called "employee", where I record any employee details, among which the employee picture. I stored the pictures and the finger prints using "Oracle sql developper" as blob type.
How can i retrieve and view all these information when i run the application?
I can easily retrieve all other types of value, but the image(BLOB type) has been a nightmare for me.
HELP PLEASE.morgalr wrote:
I believe your Binary Large Obejct will come back as an array of int, and you'll need to use BufferedImage it's associated API to get it to a viewable image configuration.I don't think BufferedImage immediately solves the problem -- this is a web app, so I assume the image will be displayed using the HTML IMG tag.
Solution: google. There are many example of how to do this. For example, any book on servlets will have an example of dishing up a dynamic image. -
How to run and pass parameters to exe file from the .txt file
hi,
i am facing problem with passing parameters to the .exe file which is run by labview.firstly i have .txt script with parameters which i have to pass to .exe file. This .exe file is also a software and that script is written for it.And now i have to create programm in labview which should fullfill following points.
1. I have to use one knob named 'Run script'.If i pressed the knob ,it should open the Browser where i can choose .txt script file.
2. .exe application should open(Path already chossen).
3. after passing the parameters .exe application should closed.
4.And labview now should update his parameter
I can just open .exe file using Exce.vi but i dont getting any idea to do more than this.can somebody please help me?
Solved!
Go to Solution.This depends on the exe file. Does it retrieve the information as standard input or does it require the information as command line arguments?
Depending on this, you can read the txt-file in LV (using the file functions) and pass the content to the System Exec.vi.

How to run a remote application (Non Java) from a Java program
Could you please tell me how to run a remote application (Non-Java) from a Java program without using RMI. Please tell me know the procedure and classes to be used.
Cheers
Ramwhat do you mean remote application.In the other pc or in your pc just apart from you application?
If the application is in your pc,the method which the upper has mentioned is
a good one!
But if the application you want to run is not in your computer,the method can't do. And you can use socket with which you can build an application listening some port in the pc which contains the application you want to run .When you want to run that application ,send the Start_Command to the listening application.Then listening application will run the application with the help of the method the upper mentioned. -

How to Generate and Display SVG Graphics in ABAP
Hi everybody,
I tried to complete the Tutorial "How to Generate and Display SVG Graphics in ABAP, Part 1" by Siarhei Ulasenka (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/ad83a990-0201-0010-d680-a189f8bc20fa).
Unfortunately when I tried the example to display an SVG Drawing in an ABAP Report I get the error message "Es ist ein Laufzeitfehler aufgetreten, ungültiges Zeichen" (english should be something like "Runtime Error, unkown character"). But it works when I open the svgfile in a new IE Window (parameter in_place from cl_gui_html_viewer->show_url). Also when I open a svg file from the local disc it works fine.
The code:
CALL METHOD html_control->load_data
EXPORTING
url = 'chart.svg'
type = 'image'
subtype = 'svg+xml'
CHANGING
data_table = lt_svg
EXCEPTIONS
OTHERS = 1.
CALL METHOD html_control->show_url
EXPORTING
url = 'chart.svg'
in_place = 'X'
EXCEPTIONS
cntl_error = 1.
Has anyone a solution? Thanks in advance for your help!

How to acces and display datas storaged in cache for a SUP 2.0 workflow?
HI to all.
I have an application with a item menu which obtains data thought a online request. the result is shown is a listview.
My problem is when my BlackBerry has no conection ( offline scenario). When I select the menu item, I obtain an error.
How to acces and display datas storaged in cache for my MBO? I have read that I can use getMessageValueCollection in custom.js to access to my datas but once I get the datas, How can associate those datas to a Listview like a online request?? Do i have to develop my own screen in html or how?
Thanks.I'm not entirely clear on what you mean by "cache" in this context. I'm going to assume that what you are really referring to is the contents of the workflow message, so correct me if I'm wrong. There is, in later releases, the ability to set an device-side request cache time so that if you issue an online request it'll store the results in an on-device cache and if you subsequently reissue the same online request with the same parameter values within that timeout period it'll get the data from the cache rather than going to the server, but my gut instinct is that this is not what you are referring to.
To access the data in the workflow message, you are correct, you would call getMessageValueCollection(). It will return an object hierarchy with objects defined in WorkflowMessage.js. Note that if your online request fails, the data won't magically appear in your workflow message.
To use the data in the workflow message to update a listview, feel free to examine the code in the listview widgets and in API.js. You can also create a custom listview as follows:
function customBeforeNavigateForward(screenKey, destScreenKey) {
// In this example, we only want to replace the listview on the "My Approvals" screen
if (destScreenKey == 'My_Approvals'){
// First, we get the MessageValueCollection that we are currently operating on
var message = getCurrentMessageValueCollection();
// Next, we'll get the list MessageValue from that MessageValueCollection
var itemList = message.getData("LeaveApprovalItem3");
