These values are from a form MStatus1.jsp which are
retrieved by a javabean named fileuploadbean:And you are sure those values are actually set? Besides, accessing fields by name strings strikes me as a little bit odd and un-OOish. But oh well..
The name strings are the names of the controls on the MStatus1.jsp file.
The controls are having their values from database which are no doubt visible on the MStatus1.jsp page.
on MStatus1.jsp page i have a button on whose click the servlet is called which uses fileuploadbean to retrieve the values from MStatus1.jsp page.

Html- jsp- servlet to retrieve data from DB

hi there, i'm a newbie of jsp programming and I'm trying to develop a simple application in order to retrieve some data from a database table. Then I want to display it.
I read lots of examples but all of them used sql queries or java code into the jsp file. Actually I would like to respect the MVC structure as much as I can.
The final thing shoul be like this:
-type in a name into the search box implemented in the html file
-the html file then calls the jsp wich get the typed in value and pass it to the servlet
-the servlet which connects to DB and makes an SQL query using the typed in value, then send the result to the jsp
-finally the jsp displays the result (in this case I'm trying to use displaytag (displaytag.sourceforge.net)).
The code must still have to be checked for unuseful stuff but it compiles and this is enough by now.
Here it is:
cerca_agenzie.html

Retrieve data from a bean into a Servlet

Hi,
I created a simple JSP file called index.jsp situated in application root, then I associated this JSP with a java bean in order to collect data after the form submission, the attribute Action inside the Form tag points on a Servlet called Login situated in the application com.myapp.servlets package.
the problem is that, using the scope="session" in the JSP page, I'm able to get catch the bean generated after the submission of the form, even the action is the Servlet called Login neither a back to the currest JSP or a redirection to another JSP, but in the same time, when I try to use bean methods to read the data (username, password) it gives null as result, I'm not able to understand the behavior of the bean which is created via Form submission but unreachable via the Servlet.
herese the code
the JSP (index.jsp)
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<jsp:useBean id="MyBean" scope="session" class="com.datalog.beans.LoginBean"/>

}thank's.

The code that would populate the bean is here:
<jsp:useBean id="MyBean" scope="session" class="com.datalog.beans.LoginBean"/>
<jsp:setProperty name="MyBean" property="*"/>
When this code runs, it
1 - creates a LoginBean (if one is not already present)
2 - Populates the loginBean from the request parameters.
But this code is currently running when you generate the login page - not when you push the submit button.
Solutions
1 - Submit the form to a JSP page which runs the jsp:setProperty tag and then forwards to your Login servlet
2 - Retrieve the request parameters in your servlet and populate the bean. The jakarta commons BeanUtils are the standard way to go here. They are actually preferable to the jsp:setProperty tag which has some "features" in its use.

Failed to retrieve data from the database when adding jdbc datasource

I'm having problems adding some tables to the selected tables list using the database expert.
I get the error messages "Failed to retrieve data from the database" followed by "Unknown Database Connection Error".
I thought it may be a permissions issue as it only affects some tables, but I can access the same tables fine using the same user through Oracle SQL Developer.
The database is Oracle 10g Express Editions
Crystal version is 12.0.0.683
Running on Windows XP
Any suggestions would be much appreciated.

Retrieve data from R3 to XI using RFC

Hi,
I want to get data out from R3 to XI through RFCs or even using idocs. I have done RFC configurations in abap using SM59 with XI as destination. I am not sure whether its right. Please guide me as to how to get data out of R3 by first sending the ID no. to R3 and then retrieving data. Can anybody help me or give me some links where i could get some information about such a scenario?
Thank you

Hi Kevin,
You need not to do any seeting at R3 side for RFC Scenarios.
For RFC Scenario:
Make RFC in R3 make sure that it is working fine in R3. take ID as a import parameter.
Import the RFC Structure in XI in Imported Objects.
Do the Design & Configuration as you do generaly.
For IDOC Scenarios :
Yuo have to do some setting in R3 and XI side . For Required setting refer following Links.

How to increase speed while retrieving data from tableand showing it in pop

Hi,
In one form ,I have used f9 key to retrieve data from table in oracle database . i.e. in any input field in my form, once I press f9 key, it execute JavaScript windows. Open command.
In that command, I called the servlet which retrieves nearly 7000 rows data from table and then it dispatch request to another jsp page which shows the related data in tabular form. The data may contain nearly 7000-8000 rows.
So when I press the f9 keys it takes around 10-12 second to open the page.
Is there any ways to open this pop up windows within 2-3 second once I hit the f9 keys.
Here with I am attaching hole code for servlet and jsp page.
Any suggestion is highly appreciated.
Thanks and Regards

try { Class.forName("oracle.jdbc.OracleDriver"); connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:bmltest","system","manager"); st = connection.createStatement(); String query = ""; if(find == null){ query = "SELECT A1.ITEMNAME,A1.TECHDESC, A1.ITEMCODE,SUBSTR(A1.MUNITCODE,1,3),A1.MUNITCODE FROM CMSTITEM A1,CMSTITEMGRP A2 WHERE A1.ITEMGROUPCODE=A2.ITEMGROUPCODE AND A2.ITEMCLASS='"+Iclasscode+"' ORDER BY A1.ITEMNAME ASC"; }else{ find = find.toUpperCase(); query = "SELECT A1.ITEMNAME,A1.TECHDESC, A1.ITEMCODE,SUBSTR(A1.MUNITCODE,1,3),A1.MUNITCODE FROM CMSTITEM A1,CMSTITEMGRP A2 WHERE A1.ITEMGROUPCODE=A2.ITEMGROUPCODE AND A2.ITEMCLASS='"+Iclasscode+"' ORDER BY A1.ITEMNAME ASC and A1.ITEMNAME like '%"+find+"%' OR A1.ITEMCODE like '%"+find+"%'"; } rs = st.executeQuery(query); while (rs.next()){ for (int i=1;i<=5;i++){ Itemnamedetail.add(rs.getString(i)); } } connection.close(); }catch(Exception e){ e.printStackTrace(); } request.setAttribute("rowid",rowid); request.setAttribute("select",Itemnamedetail); RequestDispatcher view = request.getRequestDispatcher("Itemname.jsp"); view.forward(request,response);
and here is an jsp code

First of all you will have to apply paging to show data in tables. and retrieve only those sets of data which are required. You will defnitely need to do lot of code for that. but i am hopeful, you will get some thing on net.
Second thing you can do is use AJAX. It will show your popup and will keep on loading data simultaneously. You can use JQuery and many others for that.

Can not retrieve data in Crystal Report

Hi,
I have a problem to load data from <i><b>Crystal Report</b></i> in an SBO form with the ActiveX DI object : the Crystal Report Viewer message display : <b><i>'Failed to retrieve data from the database. Details [Database Vendor Code:208]'</i></b>
It seems do not change the name of database in SQL Crystal Report query : My SQL query in Crystal Report file is a generic query : it must run with all custom database with the same datatable ; so the database name in FROM clause must be change with the SetLogonInfo : but it do not run !
Have you an idea ?

Can we retrieve Data of Single Dimension in multiplecolumns in Excel Add-in

Hi All,
I have strange requirement of having single dimension in two columns while retrieving data from essbase using Excel Add-In.
Logically I feel it is not possible however we are looking if there is any possibilty of work arround for this requirement.
Whenevr i am trying to retrieve data using a macro on a single column we are able to successfully do it. But in case of multiple columns we are unable to do it.Do let us know if there is any work arround or alternative method to handle this requirement.
Regards,
Krishna

Not completely sure what you mean by "single dimension in two columns". Normally this request comes down to wanting to show multiple levels from a dimension, e.g...
_______________"Sales"
"100" "100-10" 12345
"100" "100-20" 34567...which is definitely not possible.
If you just mean data like this (with multiple columns from the same dimension)...
________"100-10" "100-20"
"Sales" 12345 34567...then that should work fine.
If you could post a sample of what you'd like to see, it would be easier to answer.

Above message says that your registry is not consistent and some of the parameters are missing from registry.Or
Account installing SQL server does not have permission to access this. I think case can be here that account with which you logged into your system to install SQL Server might not have certain privileges. Can you take help
of domain admin account add it as a local administrator in this machine always right click on setup file and select run as administrator. Before this make sure you remove all SQL Server components from add remove program

Error while trying to retrieve data from BW BEx query

The following error is coming while trying to retrieve data from BW BEx query (on ODS) when the Characters are more than 50.
In BEx report there is a limitation but is it also a limitation in Webi report.
Is there any other solution for this scenario where it is possible to retrieve more than 50 Characters?
A database error occured. The database error text is: The MDX query SELECT { [Measures].[3OD1RJNV2ZXI7XOC4CY9VXLZI], [Measures].[3P71KBWTVNGY9JTZP9FTP6RZ4], [Measures].[3OEAEUW2WTYJRE2TOD6IOFJF4] } ON COLUMNS , NON EMPTY CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( CROSSJOIN( [ZHOST_ID2].[LEVEL01].MEMBERS, [ZHOST_ID3].[LEVEL01].MEMBERS ), [ZHOST_ID1].[LEVEL01].MEMBERS ), [ZREVENDDT__0CALDAY].[LEVEL01].MEMBERS ) ........................................................ failed to execute with the error Invalid MDX command with UNSUPPORTED: > 50 CHARACT.. (WIS 10901)

Hi,
That warning / error message will be coming from the MDX interface on the BW server. It does not originate from BOBJ.
This question would be better asked to support component BW-BEX-OT-MDX

Any way to use OBDC in SAP to access MySQL DB and retrieve data

I'd like to logon to an external MySQL DB (can de done easily enough with PHP)   but I'd like to do it with ABAP if possible.
Connecting via OBDC I should be able to retreive the data from the DB and then use it in my SAP application.
Some databases will allow connection via
EXEC SQL.
connect to :dbsid
ENDEXEC.
EXEC SQL.
    set connection :dbsid
ENDEXEC.
EXEC SQL.
open xxxxxxx for
select
...... data from external DB
from tablespace in external db
ENDEXEC.
do.
EXEC SQL.
    fetch next XXXXXX into
           :db_table_field, .... etc
             ENDEXEC.
if sy-subrc ne 0.
    exit.
endif.
insert table int_sap_table.
enddo.
EXEC SQL.
close XXXXXX
ENDEXEC.
If you can make this type of stuff work for a MySQL DB i'd appreciate the answer.
Using PHP has a drawback as you need to have it installed on the front end PC and run in Foreground.
The EXEC SQL commands run in batch which is what you need if you are talking about 100,000's of records from an external DB.

Hi Graham
Currently it doesn't seem to support MySQL.
Now that SAP has taken over again the development of MAXDB I can't see it providing direct MySQL to SAP functionality.
MAXDB is available but that would mean changing the entire architecture and we don't want to do that.
I think probably the best route to go would be to create a BAPI which is capable of performing a logon to the remote MySQL DB server, get the data and either send it back as IDOCS, an external flat file, or as an internal table depending on the volume of data to be retrieved.
The good thing about MySQL is that the command line interface makes logging on and retrieving data quite simple.
This data is actually wanted in a BI / BW system to provide for a number of business proces analyses.
I did think abut using "Web Services" but the data retrieval will essentially be done offline.
There is no requirement currently for transferring data FROM SAP back to the MySQL database ( although if you've ever dealt with top level management you know how quickly developments can change).
PHP for all it's drawbacks is the really easy way - but we'll have a problem doing this in background from the SAP servers. For foreground tasks it's a real doddle if you have php on your front end.
for example
<?php
$username = "pee_wee";
$password = "let_me_in";
$hostname = "localhost";        */* IP address of remote DB server */*
$dbh = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
print "Connected to MySQL<br>";
// you're going to do lots more here soon
mysql_close($dbh);
?>
Batch mode also seems OK also from the documentation
http://dev.mysql.com/doc/refman/5.1/en/batch-mode.html
so running an ABAP which can issue system commands (readily available) should work in theory provided the SAP server can connect to the remote MySQL server machine.
Thanks for your suggestions however
Cheers
