JAVA and BEx

We still use BEx 3.x . We think to switch using BEx 7.0. If we like to run BEx 7.0 with Excel, do we need the Java-Stack??
Thank YOU!!! ;o)

Deepu,
We are just beginning a 3.5 to 7.0 upgrade project and I too thought I understood the documentation to say that BI java was required to use the 7.0 Bex tools, so I find your response very interesting.
So you are actually using the BEx 7.0 query designer and Excel without the java stack? That makes a huge difference in what we thought we would be able to do, as current plans are NOT to include BI java, as we are under a tight timeframe, and are working under the assumption that we would need to do a unicode conversion as a prereq to installing BI java.
I am also very curious as to whether you found it necessary to upgrade hardware, CPU or more importantly, memory.  One of our Basis guys is telling us we would need lots of memory to run BI Java, perhaps double or even triple what we currently have.  This seems out of line with other SAP projections that we would need approximately 25% more server memory.  So any info you can provide to clarify  the BEx - BI Java issue, or Memory - BI Java issue would be greatly appreciated.

  • BI Java and BI ABAP -RSPLAN issue

    Hi All
    We are working with BI system ,using BI 7.0 Java and BI ABAP as separate systems on same host.
    Already run the template intaller for BI Java and ABAP integration.
    But facing some issue ,when going ot BI ABAP and RSPLAN and clicking the Start Mideller
    it is opening a browser as http://host:8000/sap/public/myssocntl?sap-client-XXX
    Since this is not correct and it should open BI Java portal instead of ABAP stack page.
    Instead this should open a Url like this http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler?
    I check on BI ABAP system under SAP Reference IMG -> SAP Customizing Implementation Guide-> SAP NetWeaver _> Business Intelligence-> BI Integrated Planning -> Settings for Starting the Planning Modeler.
    There the default Url is BEx Portal Server and the url is        
    http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler
    Can anybody let me know why this is going to ABAP server instead it should go to Java.

    Venkat,
    Thanks for your response. Please note, however, the transaction RAD1 does not exist. Let me provide more details about the current settings of the InfoObject.
    The Characteristic is 'Item' (0CS_ITEM) and upon going to RSA1 >  Modeling > InfoObjects > Item (0CS_ITEM) > Right Click > Display > Business Explorer (tab) > Text Type is set to 'Long Text' and BEx description is set to 'Long description' already.
    When I run/execute the query with this Item characteristic, the results in BEx Analyzer is showing appropriate long text, however, Crystal Report for Enterprise shows short text only

  • Communication between Abap and Java and Java to Abap

    HI,
    I have installed BI 7.0 and the user complaints that BEx WEB Application Designer Query results are not showing up in the WEB URL Link.
    and the BI user suggests that communication between Abap to java and Java to Abap has to be done?
    How to setup ABAP to JAVA and JAVA to ABAP communication?
    Regards,
    Magham.

    Hi,
    Jco conn from ABAP to Java
    =====================
    You can use the JCO RFC Provider Service of the Web Application Server for your ABAP to Java calls.
    The steps involved in that are
    1. Configure destination in SM59 in SAP.
    2. Create RFC Destination in Visual Admin.
    3. Create a stateless session bean with JNDI name as the name of calling function module in SAP.
    4. Add a business method public void processFunction(JCO.Funtion fn) which is called by the JCO RFC Provider Service. The name should be 'processFunction'.
    5. Set library references in application-j2ee-engine.xml to type weak for the following
    a. com.sap.mw.jco.
    b. com.sap.tc.Logging (if you are using the logging api )
    Here is the sample code for the EJB biz method
    Business Method.
    public void processFunction(JCO.Function function) {
    try {
    // Get the import parameters for the function module
    JCO.ParameterList importList = function.getImportParameterList();
    logger.infoT("The value sent is" +
    (String)importList.getValue("USER_NAME"));
    // Set the export parameter value for the function module
    JCO.ParameterList export = function.getExportParameterList();
    export.setValue("From EJB", "RETURN");
    function.setExportParameterList(export);
    catch (java.lang.Exception e) {
    e.printStackTrace();
    Jco conn from Java to others(ex:ABAP)
    =====================-==========
    • Open Visual Admin(C:\usr\sap\SID\JCxx\j2ee\admin\go.bat) and connect to server
    • Go to Destinations service
    • Open HTTP Settings Tab
    • Add/Edit destination SLD_DataSupplier and type following values
    URL – http://xyz.corp:53000
    Authentication - BASIC
    User – dynproxxx
    Password - bp52st000
    • Press save and test (if you get response code 200 everything is o.k.)
    • Add/Edit other HTTP Destination named SLD_Client with the same values as SLD_DataSupplier:
    URL – http://xyz.corp:53000
    Authentication - BASIC
    User – dynproxxx
    Password - bp52st000
    • Press save and test (if you get response code 200 everything is o.k.)
    • Go to SLD Data Supplier service.
    • Press the button named: Send the Data to SLD and confirm triggering SLD Data transfer (if you receive successful message everything is o.k.).

  • What is difference between bex analyser and bex browser

    what is difference between bex analyser and bex browser . please explain what are use of both and what we do in both.

    hi
    Bex Browser
    The Business Explorer Browser (BEx Browser) makes it possible for you to access all document types of the Business Information Warehouse that are assigned to your role or that you have stored in your favorites. You can select and open documents assigned to you in the BEx Browser or store and manage new documents in the BEx Browser.
    Document types that you can work with in the BEx Browser are:
    · BW workbooks
    · Documents that are stored in the Business Document Service (BDS)
    · Links (references to file system, shortcuts)
    · Links to internet sites (URLs)
    · SAP transaction calls.
    · Web applications and Web templates
    · Crystal Reports
    Bex Analyser
    The Business Explorer Analyzer (BEx Analyzer) is the analysis and reporting tool of the Business Explorer that is embedded in Microsoft Excel.
    Features
    You can call up the BEx Query Designer in the BEx Analyzer, in order to define queries. Subsequently, you can analyze the selected InfoProvider data by navigation to the query created in the Query Designer and create different query views of the data. You can add the different query views for a query or for different queries to a work book and save them there. You can save the workbook in your favorites or in your role on the BW Server. You can also save the workbook locally on your computer.
    Beyond that, you can precalculate the workbook and distribute it by e-mail to recipeients or you can export it to the Enterprise Portal and make it accessible to other employees in the company.
    You can start queries in a standard view (with a Standard Web Template set up in Customizing) in the Web browser and forward the URL or continue to navigate on the Web. Similarly, you can export the Web query to MS Excel 2000.
    Overview of the Functional Area of the BEx Analyzer:
    ·        BEx toolbar
    You access the functions of the BEx Analyzer from the BEx toolbar, which takes you to the BEx Open dialog box where you can open existing queries, or to the BEx Query Designer where you can create new queries or change existing queries.
    ·        Evaluating Query Data
    The BEx Analyzer offers convenient functions for evaluating and presenting InfoProvider data interactively. In the BEx Analyzer, you can add queries to workbooks, navigate within them and refresh the data. You can also process the queries further in Microsoft Excel or display them in the Web browser in a default view.
    Navigation of a query allows you, for example, to filter characteristics on a single value, drilldown on all values for a characteristic, regroup characteristics and key figures in the rows and columns of the results area, or hide key figures. Navigation results in different views of the InfoProvider data. In addition, a range of further functions is available which allow you to edit a query interactively (for example, sorting, cumulated output, among others). In addition, you can use the editing functions in Microsoft Excel in order to set up individual format templates, to print results areas, or to create graphics.
    ·        Queries in Workbooks
    Queries are inserted into workbooks so you can display them. When you insert a query, a link is made between the cell areas of the worksheet and the data of the InfoProvider upon which the query is based. A link therefore exists between the Business Explorer and the Business Information Warehouse Server (BW Server).
    When inserting a query into the workbook, a VBA routine is automatically generated in the workbook. You can also connect the Business Explorer with your own VBA programs (Visual Basic for Applications).
    You can create workbook templates, into which you can insert your queries. Workbook templates can contain pre-determined items for the area of the query, formatting settings, logos, VBA macros, and so on.
    ·        Precalculating workbooks
    You can precalculate and distribute workbooks with the BEx Broadcaster, which is a Web application you get to form the BEx toolbar. The system generates MS Excel workbooks with historical data. You determine the time for precalculation yourself: You can have workbooks precalculated at a predefined time or they can be precalculated whenever data in the underlying InfoProvider changes. You can have the precalculated workbooks sent by e-mail or you can export them into the Enterprise Portal, where you can make them available to employees within your company.
    Activities
    To start the BEx Analyzer, choose Start ® Programs ® SAP Front-end Business Information Warehouse ® SAP Business Explorer Analyzer.
    You can also access the BEx Analyzer via SAP Easy Access ® SAP Business Information Warehouse ® SAP Menu ® Business Explorer ® Analyzer or in the Business Explorer Browser using the Business Explorer Analyzer symbol in the menu bar.
    Hope this will solve your issu

  • Difference between bexbrowser and Bex analyzer

    Hi,
       can any body tell me  what is the difference between bex browser and bex analyzer  and how end users will access the reports and how they access SAP.

    Hi
    *BEx Web Analyzer *
    The BEx Web Analyzer is a standalone, convenient Web application for data analysis that you can call using a URL or as an iView in the portal.
    The Web Analyzer allows you to execute ad hoc analyses on the Web: When you have selected a data provider (query, query view, InfoProvider, external data source), the data is displayed in a table with a navigation pane. You can navigate to the data and use other Web Analyzer functions available in the application toolbar. For example, you can change the type of data display, use the information broadcasting functions to broadcast your analyses to others, and create printable versions of your analyses.
    In the Web Analyzer, you can save the data view generated from navigation and analysis as a query view by choosing Save View in the context menu, and you can save the ad hoc analysis by choosing Save As. When the query view is saved, only the data view is saved; when the ad hoc analysis is saved, the entire Web application is saved, including the properties of Web items and the layout of the data.

  • Shortened Fiscal Year and its impact on BI back end and Bex reports

    Hi All,
    Our client is making some changes to the fiscal year period.
    Becuase of some business requirements, we will have to shortened the fiscal year.
    Can you please suggest - what are the watch points when we do this?
                                            - what will be the impact to BI back end and Bex reports?
    Thanks,
    Nisha

    Hello Nisha,
    Since the fiscal year (Infobjects - 0FISCYEAR and/ 0FISCPER3) is compounded with fiscal year variant, therefore maintaining the correct variant in BI will automatically take care of showing the data correctly.
    So there are two things to be maintained in BI:
    1) To see that the variant definition.
    2) If you need to display the text of the fiscal periods, then the correct texts.
    Let me know if you need more clarifications.
    Regards,
    Shweta

  • How to get return value from java and read by other application?

    i want to read return value from java and the other application read it.
    for example:
    public class test_return {
        test_return(){
        public int check(){
            return 1;
        public static void main(String args[]){
           new test_return().check();
    }from that class i make as jar file. How to read the return value (1) by other application?
    thx..

    If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
    About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
    EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

  • Problem with java and flex web service

    Hi,
    I have a basic web service written in java using jax ws 2.1
    ri. I need to call it from Flex using the WebService class
    Annotations for the java web method :
    @WebMethod

    login method and attempts to call it fail. If I set the web service
    to RPC based using @SOAPBinding , the method is found but then
    there are issues with the authentication header.
    What do I need to do to get flex web services communicating
    succesfully with java ?
    Are there are any known compatibility issues ? Or guidelines
    for going about this ?
    Any help would be appreciated

    well Shay,
    i've used JDev's tools to developer and to deploy the web service: the war and ear files are automatically generates you to the end of the process.
    I have included all the files java and the compiled classes, but I do not have files jar.
    But don't works: if i create only one java class with all code inside then it works fine!!

    Using java, I get the following results:
    The value is 4.0
    The value is 4.0
    The value is 99.0
    But using javaw, I get the following results:
    The value is 4.0
    The value is 4
    The value is 99
    Any ideas why this is so?
    Thanks for any help.

    I used JBuilder to run the following code and Jbuilder uses javaw.
    By the way, the correct answer is the one using java right?

  • Problem with Java and Zip Files

    Hello there everyone. I have a problem with trying to zip up directories with empty folders in them. They zip fine with my code, but according to winzip, the number of files in the archive is incorrect. It's supposed to have a total of 288 files in it, but when it's zipped up, it only says 284. I mention specifically the "empty directories" note because the zipping works fine without empty folders.
    Below is the code for the zip method:
    public static void zip(File[] list, File zipfile, File zipRoot)
         throws IOException {
          if (!zipfile.exists()) {
                   zipfile.createNewFile();
              else if (!zipfile.isFile()) {
                   throw new IOException("The zip file, " + zipfile.getAbsolutePath()
                             + " is not a file.");
              if (list.length == 0) {
                  LOG.error("The list of files to zip up is empty.");
              for (int i = 0; i < list.length; i++) {
                   if (!list.exists()) {
                        throw new IOException("The file or directory, " + list[i].getAbsolutePath()

                        if (list[i].listFiles().length == 0){
                             ZipEntry entry = new ZipEntry(entryName + "/");

    The files look like they're there, but I need the system to be able to determine the number correctly. 
    Here's the interesting thing:  It zips the files, and then when I use the size() method for zip files in java, it says 284 files.  But when I unzip, it says 288 again.  It's like there's files missing when compressed, but when decompressed, they return.  Note that the files are actually there.  If I open the archive in a third party app such as Winzip AND Winrar AND IZarc, they all show 288 files.  Any idea what would make the number of files appear incorrectly in a zip file when zipped by java with the code above?  Thanks in advance.

    I figured out the problem. When zipping files in windows using winzip, it doesn't explicitly count folders as a "file/folder" as a file in itself. It will create the folders for files to go in, but the folder itself will not be 'counted' when you query the info of the file itself. You have more control of the zip file in java, and can count the folder as a file or not.

  • Compability problem with Java and Python  RSA algorithm implementation

    I have client server application. Server is writtein in python, client in java. Client receives messages from server encrypted with RSA (http://stuvel.eu/rsa), and I'm unable to decrypt it. It seems that this is RSA algorithm compatibility problem. I'm using algorithm from java.security package, instatinating Cipher object like this: c = Cipher.getInstance("RSA"); . I noticed that this algorithm produces for input blocks of lengtrh <=117 ouput block of length 128. Server I guess uses the most triviall impelentation of RSA ( (1 byte is encrypted to 1 byte) So i want to make my java algorithm compatibile with this one which server uses. How to do that ? Do i have to instatinate Cipher object in different way ? Or use another library ?

    azedor wrote:
    First you said it was no good because it could only handle <= 117 byte inputs, now you say it is no good because it produces a 128-byte output. You're not making sense.First i said that this two RSA implementations are not compatibile, and first reason i noticed firstly is that Python imlementation for input of length N produces cryptogram of the same length. Not true. In general, the RSA encryption of any number of bytes less than the length of the modulus will produce a result of length near that of the modulus. When N is less than the length of the modulus, it is rare that N bytes of cleartext produces N bytes of ciphertext.
    Java implementation for data block of length <=117 produces alwasy 128 bytes of output.Pretty much correct and very much desirable. This is primarily a function of the PKCS1 padding which is used to solve two basic problems. First, as I alluded to in my first response, it is the nature of the algorithm that leading zeros are not preserved and second when the cleartext is very small (a few bytes) the exponentiation does not roll over and it is easy to decrypt the result. Both these problems are addressed by PKCS1 padding.

    After what sabre150 said i think of giving up idea of translating Python code to Java and considering to use another assymetric cryptography algorithms on both sides. Can you recommend me sth what should be compatibile with Python ?This seems to be at odds with your statement in reply #3 "Also have acces only to client code so i have to change sth in java." ! This statement is why I said "I suspect ... you have dug a deep hole".
    In your position I would use the Python bindings for openssl. Once more, Google is your friend.

  • Events problem with (Java and ActiveX)

    Hi,
    I use an ActiveX component with Java and i've got a problem with events.
    Java classes were generated with Bridge2Java (IBM).
    In order to manage events I added a listener in my application :
         javaMyActiveX = new MyActiveX();
         javaMyActiveX.add_DMyActiveXEventsListener(new _DMyActiveXEventsAdapter());
    I also added a constructor in the _DMyActiveXEventsAdapter class and I fill the body of methods.
    The ActiveX generates two types of events :
    - The ones are directly generated by methods.
    - The others are generated by a thread.
    With MS Products (VB, Visual C++, Visual J++), I catch all events.
    With java (jdk 1.4), I catch only events generated by methods.
    Can anyone help me.

    I'm not 100% sure, but the last time I used that bridge, it only worked if you ran your Java app within a Microsoft VM.
