Web Dynpro application connecting to oracle

Hi all,
i want to create a web Dynpro application which will fetch data from oracle database.
Can anyboby guide me with some documents.
Thanks in advance.

Thanks for your quick reply!
  I am trying in another way.I've created a WD application and in custom controller I've put the code for connection, copying the retrived data into context and trying to display the data in one view.
CODE:
DriverManager.registerDriver(
              new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection(               "jdbc:oracle:thin:@oracle server ip:port:sid",
     "user name",
     "password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from table");
if (rs != null)
  while ( rs.next() )                     
     //code for copying data into context
stmt.close();
conn.close();
Error(No class defination found) is at first line i.e. new oracle.jdbc.driver.OracleDriver().
I've put classes.zip in lib and build path as well.
Regards,
Sarika.

  • Web Dynpro Application connecting to incorrect R/3 instance

    Hi,
    We have newly configured EP.
    We are facing strange problem with web dynpro applications.
    They are accessing data from incorrect instance of R/3 system,i.e, if correct system instance is x , they are accessing data from y instance, on the same R/3 server.
    We have checked JCO connections. SID in JCO connection is of the correct instance.
    We have also checked SLD, but are not able to find out the root cause of the problem.
    Are there any other configuration, settings required?Are there any settings required on R/3 side?
    Can we some how track entire process from JCO to R/3?
    What happens after fetching server details from SLD? Is there any other step before connecting to R/3?
    Can anyone help on this?
    Thanks in advance,
    Apurva

    Hi,
    I have checked alias name (System ID) used in JCO connection.It is correct.
    I have also checked System ID in SLD.
    Is there any other configuration check required?
    Thanks,

  • Web Dynpro application connecting to sql server

    Hi,
    I want to fetch data from SQL Server using webdynpro. Can anyone suggest me the steps to do this? I need to connect the SQL Server also to portal. I found one using visual admin another using system object in portal. Which is better way and how can use that connected system in coding to retrive data.
    Please help me. Points will be awarded for helpful answets.
    Thanks,

    Hi,
    You place the code where ever you want to establish the connection to the data base which is located remotely in a diffrent IP from NWDS.
    The requirement for this we have 3 jar files.Which you have to copy in the lib folder.
    those are:-
    1.msbase.jar
    2.mssqlserver.jar
    3.msutil.jar
    XX.XX.XX.XX->IP Address
    XXXX---->Port no
    Code:-
    Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
    conn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://XX.XX.XX.XX:XXXX;databaseName=TrackingSystem","sa","sa" ) ;
    Statement st = conn.createStatement();
    String str = "select * from User Table";
    ResultSet rs = st.executeQuery(str);
    while(rs.next())
    String str1 = rs.getString(1);
    wdComponentAPI.getMessageManager().reportSuccess(str1);

  • Connect Web Dynpro Application to a Web service

    Hi experts,
    I am trying to connect a Web Dynpro application to a SOAP Web service.
    I have downloaded the WDSL code and save it to a file in my hard disk.
    I used the create model wizard (Import adaptive web service model) and created a model in my Web Dynpro application.
    I have connected the component controller with the model and the view of the application to the controller.
    All content node elements that have created automatically in the model, have in cardinality property the value 0..1.
    I created input elements in the view but they are gray and not available (disabled).
    The read only properity of the input elements has the value "false".
    I tried to initiate the input element by putting the following code in wdDoInit() but with no luck.
    wdContext.nodeRequest_ProcessTransaction().nodeProcessTransaction().nodeTransactionRequest().nodeHeader().nodeMerchantInfo().currentMerchantInfoElement().setAcquirerID("xxxx");
    Can someone help with this?
    Thanks in Advanced.

    Hi,
    After importing the model, you need to create the instance for the model. Instantiate the Request object and then set the input parameters. Then you have to call the execute function, then the model will be executed and you will get  the data.
    Also instead of putting the code which you have wriiten in init, you can use:
    wdContext.nodeMerchantInfo().currentMerchantInfoElement().setAcquirerID("xxxx");
    You can directly access the node, no need to traverse the whole hierarchy.

  • Web dynpro - database connection

    Hi all,
    i intead to make a web dynpro application which will store the data entered by the user in an oracle database
    How am i to obtain webdynpro - oracle connectivity?
    points assured for Help

    Hi Shobhendra,
    The simplest way is to use Visual admin. For that , do the following
    1.Run Go.bat in the server to open Visual Admin.
    2.Select Cluster->JDBC Connector
    3.In Runtime, Create a driver of any name(Say mydriv). Select classes12.jar for that
    4.Create a new datasource(Say myDS). There specify the
    driver class as oracle.jdbc.driver.OracleDriver
    database url as jdbc:oracle:thin@IPADDRESS OF ORACLE SERVER:PORT:SID
    driver as mydriv
    The PORT will usually be 1527 or 1521.
    For IPADDRESS, PORT and SID, u have to contact db admin
    5. In additional , select Vendor or Native SQL
    6. Test the connection using Monitoring tab. If green line is coming, then connection is successful, otherwise, the parametes u used will be incorrect
    7.In ur webdynpro code, inorder to get the Connection to oracle, add the following
    InitialContext ctx=new InitialContext();
    DataSource ds=(DataSource)ctx.lookup("jdbc/myDS");
    Connection con=ds.getConnection();
    8. Press CTRLSHIFTO

  • Error - Creating a Web Dynpro Application Accessing ABAP Functions

    Dear All,
    we are trying to implement a web dynpro application with accessing ABAP functions.
    Previous tasks:
    -     insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
    -     equipped the JCO connections with the web dynpro content manager (ping and test = OK)
    It’s the standard tutorial out of the SDN called “Creating a Web Dynpro Application Accessing ABAP Functions”.
    Some hints:
    -     There are no errors after the implementation and the “rebuild” of the project in the NWDS
    -     The auto deployment works fine to the development runtime system. The application is shown in the Web Dynpro content manager
    -     The In the build log I found these entries:

    There two different URLs in use.
    Start via NWDS:
    http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
    Start via web dynpro content manager:

    For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
    Any ideas about the system behaviours (different URLs and missing functionality)?
    Thanks a lot in advanced!

    The Error has been solved – The implementation of a method was missing....

  • Passing a parameter while calling a web dynpro application on portal

    hi
    I am having a web dynpro application which retrieves data from R/3 system via RFC using Jco destinations define in the Portal.
    Now we have different kinds of portals running on the same WAS, now I want the application to run which access data from different R/3 systems thru different JCo destinations.
    I need to create a logic such that mu application runs fine on any portal with any Jco destination.
    Is there any provision to achieve this.
    kindly let me know about this.
    Thanks and regards
    kris

    Gopi,
    there's an parameter called "sap-wd-arfc-useSys" you can pass to the application, to change the used JCo-Connection (read more at http://help.sap.com/saphelp_erp2005/helpdata/en/f4/651741f163f023e10000000a155106/frameset.htm)
    so, if you're running the WD-aaplication on <b>one</b> WAS and call it from different portals, you have to create three (or six with the META-connections) JCo-Connection on your WD-WAS.
    In a WD-application you can access URL-Parameters with:
    WDWebContextAdapter.getWebContextAdapter().getRequestParameter("<your URL Parameter-Name>");

    Amr Azim,
    You must have logged in thru a dedicated connection to any server through say VPN before deploying.This way the sdm uses the same login as that of already establised connection.
    So 'sign of'  all connections to any servers before deploying and redeploy your application.Here you will be prompted to supply the sdm password and deployment shall proceed.

    At the same time if more users are deploying then you may such 'deployment aborted' errors check if there are more child instances for the J2EE engine.If not ask your basis administrator to create more child nodes to balance the load on the server instance.Also You can find out the server details at
    "http:
    <hostname:portnum>\index.html"select system configuration-you can get the details of the SDM and the j2ee engine from there.You need to have proper credentials to get the information from the above url.
    Provide those details in the NWDS.

  • Exchanging data between a Web Dynpro application and SAP Web Shop

    I'll try to keep this as clear as possible:
    1) We have the SAP Internet Sales system running, which has a series of Business Object classes and corresponding Backend Layer objects that can return data from several sources.
    2) We are able to create our own Backend Layer objects that would return data from a component called IPC, which is a Java component.
    3) I would like a Web Dynpro application to retrieve data from this backend layer object, but I am not experienced enough with Java to know if what I want to do is possible. I don't think that I can use JCo, because I am trying to get a Java component (class?) in Web Dynpro to access a Java class remotely.
    4) I think I am asking is this: is there a way for a Java to Java connection to be created, much like Web Dynpro can use JCo to connect Java to ABAP systems?
    If this is a glaringly obvious question to Java programmers, my apologies!

    Somebody on another forum recommended using RMI. Which would be the better option in terms of ease of implementation?

    2. Go to Secure Store and change the password for the property admin/password/J2E (This password should same as the one you are trying to login to portal)
    3. Click Add
    4. Click Save and restart your server.
    Should be able to deploy your components.
    Happy deploying

  • HTTP 500 internal server error while starting abap web dynpro application

    Hi there,
    i have some problems concerning my web dynpro abap configurations in the system. When i start an application the browser appears and displays the http 500 internal server error.  The required icf nodes are activated, as far as i know. the following properties are set:
    hostname: aet
    port: 8000
    The generated url for the web dynpro application looks as follows:
    http://aet.ls3001:8000/sap/bc/webdynpro/sap/zwdr_test?sap-language=EN
    Maybe anybody of you out there has an idea for that situation.
    Thanks for your afford and kind regards,
    Albert

    Hi Ulli,
    the error message says:
    UNKNOWN HOST
    Description: Unable to locate the server named "aet.ls3001" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.
    So the problem is the hostname.
    When i replace the hostname with the ip of the server, the following error occures:
    COULD NOT CONNECT
    Description: Could not connect to the server "10.18.187.9".
    But with SAPLogon, its possible to connect on the server by filling in the ip adress.
    Kind regards,
    Albert
