Java dictionary database table in web dynpro application

Hi,
I want to access java dictionary database table in my web dynpro application in java.
Right now I have created one java dictionary DC.
and in that Dc i have created two database table .
Now I want to use this table in my web dynpro application.
Can anyone help me.

You can use the Dictionary Projects to create tables in Database. You must use codes to access these database tables that is created using Dictionary projects.
You have to use the DataSource in order to get connection ; Use Visual Administrator to see the data source name.
You can use the following code to access the database table.
ResultSet result = null;
try
     InitialContext initialcontext = new InitialContext();
     DataSource datasource = (DataSource)initialcontext.lookup("jdbc/<DataSourceName>");
        Connection connection = datasource.getConnection();
     Statement statement = connection.createStatement();
     result = statement.executeQuery( <Query>);
     connection.close();
} catch (NamingException e) {
     // TODO Auto-generated catch block
          e.printStackTrace();
} catch (SQLException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();

Calling a Standard SAP transaction VA03 from another web dynpro application

Hi All,
I have a requirement wherein I need to call the standard SAP transaction VA03 whenever a sales order is selected in some other we dynpro application so that the sales order gets displayed.
No regarding usage of OBN for the above functionality I have certain queries:
1. In order to call VA03 do I need to create a transactional iview for it or is there any direct method.Also how to pass this sales order number as parameter to the T.Code.
2. Can we use standard business object BUS2032 for OBN or a new Business object is created.What exactly is the purpose of these standard business objects in portal and when should they be used.
Thanks in advance
Aman Gupta

Hi Aman - Do you have a portal team in your project or you have to create the IVIEWS yourself?
I do have a portal team and I dont know how they create the IVIEWs but for example, I will go to my portal team and I will ask them to create an IVIEW for TCODE VA03, they will created and they will tell me the input parameters they entered for the IVIEW so I can call OBN and display in webdynpro.
SAP in SRM has webdynpro e.g. for BUS2121 and they have an IVIEW already implemented in the portal context pointing to the webdynpro of BUS2121 so we can used the IVIEW by calling OBN and passing the parameters; in my case the object_type will be 'shc' and the operation will be 'display' and the paremeters itab will be the GUID of my shopping cart, that way the OBN can understand which Shopping cart open and in which operation mode.
I also did something like your requirement, I need it to display a specific case in Records Management but SAP has a standard IVIEW for records management 'RMREGEDIT' that didn't work for my requirement so I went to SE38 created a program that displayed the case based on GUID and I created a TCODE of my custom program. Portal team created a custom IVIEW of my custom TCODE and they told me the input parameters to call the TCODE in OBN and I pass in the itab parameter the GUID of the case using the FM that I post before.
The action to call the OBN is in the event handler ON_CLICK of my ALV and the action is getting trigger when the user actually clicks a HYPERLINK in the ALV.
Hope this helps you!
Please feel free to ask me more details if you need.

Deletion of data of R/3 table using Web Dynpro

Hi Experts,
I have to delete some records from R/3 table CATSDB using Web Dynpro form. I am using BAPI_CATIMESHEETMGR_DELETE for this purpose. Can you please let me know the steps to accomplish this exercise.
I have displayed the records of CATSDB using one custom made BAPI. Using this BAPI, I am able to display the data. I have created one button called "Delete Data" button on the form. I have called BAPIs using following code:
public void onActionDeleteData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionDeleteData(ServerEvent)
    wdThis.wdGetTimesheetCompController().executeBapi_Catimesheetmgr_Delete_Input();
    wdThis.wdGetTimesheetCompController().executeBapi_Transaction_Commit_Input();
//@@end
However, when I am selecting the record and trying to delete the record, record is not getting deleted. Can you please help me in resolving the issues? What is going wrong?
Regards,
Brian

Hi Ashwani,
I have checked the BAPI - BAPI_CATIMESHEETMGR_DELETE. I am unable to delete the record using even R/3 screen. For deleting the record, I have to provide following four parameters:
PROFILE, TESTRUN, RELEASE_DATA and AGENT.
I don't know what should be the value of TESTRUN, RELEASE_DATA and AGENT. I know only the value of PROFILE. From ABAPers, I have come to know that in order to delete the reccord I must provide the value of COUNTER. However, the BAPI, BAPI_CATIMESHEETMGR_DELETE is not asking me to enter the COUNTER.
Can you please let me know how to delete the record from BAPI using R/3 screen. After that I will try to delete record using Web Dynpro application.
Regards,
Brian

How to create dictionary table using web dynpro?

Dear Experts,
Please clarify my doubts.Im new in this EP development.
Im using EP6 portal with NWDS6 for dev.
My Doubts are :
Im trying to develop a web dynpro application which captures some data and insert/update in Table.
=> If we create a structure Dictionary in web dynpro application will that automatically create the table in Portal database?
=> If it is automatically created how to insert or update that table.
can any one plz help.
thanks and regards,
Viswes.

Hi Visweswara
This will use the concept of EJB.
Refer these for creating Dictionary tables...
[https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70929198-0d36-2b10-04b8-84d90fa3df9c]

As far as answer to your second question is concerned,
=> If u create a structure Dictionary in web dynpro application it will not create the table in Portal database..
You can access that table via creating a web dynpro iview in Portal..
Only application can accessed after deployment via iviews in Portal..
Thanks...

We have a requirement where we are displaying the data of the table KNA1 in a table form (Web dynpro) which is editable.for the field NAME1 there must be drop down box which contain some values , so that for any row user can select one of the value and then when press SAVE button the table KNA1 should be updated with the new value of NAME1.
Can you please let us know how to do this.
Thanks
Mahesh

>Can you please let us know how to do this.
Which part of what you describe and what exactly are you having problems with. You can of course change the cell editor of your column to DDLB. Is that where you are having problems. Or are you trying to decied between DDLBByKey and DDLBByIndex. For that I would suggest you read the following:

FETCH DATA FROM ORACLE DATABASE USING Web Dynpro

I want to fetch data from ORACLE database using Web Dynpro.How can I do this?

1) Are you sure that you get no results? It sounds like you are having name resolution issues, which would imply that you should be getting an ORA-00942 error indicating that the table doesn't exist (or that you don't have access to the table). If you are not seeing this error, I would tend to suspect an overzealous exception handler.
2) What database account owns the table? What database account is your ASP.Net application using to connect? Assuming these two accounts are different, your application would either have to
- Explicitly prefix the table name with the schema name
- Have a public or private synonym that maps the table name to the fully qualified identifier schema_name.table_name
- Issue the command ALTER SESSION SET CURRENT_SCHEMA = <<schema name>> in each session, in which case all queries in the session would use the specified schema name as the default if no schema name is prefixed.

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!
- Tony.

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

Web-dynpro application -ERROR: ICF service node "/sap/bc/webdynpro/sap/zqm_cto_arr_general1" does not exist (see SAP Note 1109215) (termination: ERROR_MESSAGE_STATE)

i have created my web-dynpro application in development. and sent to quality . whenever i will execute my dynpro in quality i got one message
ERROR: ICF service node "/sap/bc/webdynpro/sap/zqm_cto_arr_general1" does not exist (see SAP Note 1109215) (termination: ERROR_MESSAGE_STATE)
whenever i saw sicf transaction my web-dynpro is not seen . my dynpro application name is more then 15 character. what i will do . please give me valuable suggestion.....

Hi Ashok,
for your requirement the application is not exist in particular place. It means, the webdynpro application is saved at different package or different location.
Please change the webdynpro component name and save it in particular request in package, then transport it to quality ..(development server )
then go to SICF t.code .. sap->bc->webdynpro->sap->find out your application and activate the service of your webdynpro application.
Now test it ... this solution might helpful to you .

I am trying to use a database table in Web Dynpro. For this, o already created and deployed a dictionary project and one database table in that project. In my web dynpro project when i am accessing this table columnname it works fine, but its not allowing to insert the data.It is giving following error:
The SQL statement "INSERT INTO "TMP_2" ("NAME") VALUES ( "ASDFGH") " contains the semantics error[s]: - 1:36 - the column >>ASDFGH<< is undefined in the current scope where NAME is my column name.
Also when i change some column name or add one more column to my table and then deploy it. After this, when i run my web dynpro project it doesn't show the updated column name and column count.
Please help.
