Database programming with webdynpro java

Hi,
I'm trying to read a database table and fill a grid in web dynpro project.
Table is in portal database.
Is there a sample code to do this operation?
Thanks

Google for JDBC code.

Can you be more specific ? Are you talking about the backend table or the table that you wanna publish on the portal (through your JDBC web dynpro project) ...

Build gui for existing oracle database tables with webdynpro java?

hi
i want to build a GUI to maintain existing oracle tables
so far we used oracleFORMS to do so
is there a good approach for webdynpro java? or do you recommend other sap tools?
can we generate the gui with a wizard based on the fields in the table?
do we have to generate sql statements or type in manually?
regards
joerg

Hi Joerg,
generally that is possible, but you'll have to implement the data access by yourself, by means of EJB or another Java persistance framework such as JDO, SQLMaps, Hibernate, whatever...
Web Dynpro allows to build a GUI based upon a model - in this case this could be some POJOs (DTOs) representing your database tables, which are communicated to the GUI by your data access layer. Consider a model as a simple Java bean representing database data.
This approach would require to build a data access layer which incorporates manually generated sql statements, so you'll have to have expert database and java knowledge.
There might be other approaches, this is just to demonstrate one working possibility.

Christian

Calling RFC with webdynpro java (in NetWeaver Developer studio)

Calling RFC with webdynpro java (in NetWeaver Developer studio)
Hi,
I want to call only one parameter RFC with webdynpro.
Flight example is very complex.
I want to push a button and pass parameter to RFC input and call RFC.
After execution some message must appaer on the screen.
Is there a step by step .pdf?
Thanks.

Hello Cemil,
There's a seperate Web Dynpro forum for such posts, you should take a look there.
Nonetheless, the classic tutorial is the FlightList. If I was you, I would make sure to do this tutorial step-by-step as it should give you the fundamentals for understanding aRFC. On top of that, it's most likely already available to you on your SAP system...
Here's the link:

SAP MDM Connection with WebDynpro Java

Hi,
I am working with SAP WebDynpro Java (UI) and SAP MDM (Database). I had added the respective jars-
a) I want to test whether I am able to make a connection to the MDM server. Let me know input parameters (sample source code required) which I need to pass from SAP WebDynpro Java (UI) to make a successful connection to MDM (DB). Please let me know this in details.
b) After making connection to MDM, I need to write a query where I need to pass Lot No1 & Lot No2 from WebDynpro Java (UI) & check in a MDM table numbers of records existing and later display the corresponding records details (sample source code required) in the screen.
Your inputs will be highly appreciated.
Thanks.

Anmol,
Depending on what version of WAS you are on...you might have WDJ components available that you can use. Just to offer a different view on your question.
Otherwise follow the links above or the following link to get sample code.
Read MDM ItemDetail Record in WDJ
You should get lots of sample code on SDN.

Integrating flex with webdynpro java

hi,
iam new bie in webdynpro java.please tell is there possibility of integrating flex in webdynpro java,if so what are the prerequisites for it.

Hi
This is possible through Adobe Flash Islands under Mimes folder in your Webdynpro project. You create flex objects in FlexBuilder and generate the .swf files. Then the swf files need to be placed under the Mimes folder of Webdynpro Project from which they can be accessed.
Follow the link below for details :

Database connection with a Java applet

I am having trouble figuring out what I am doing wrong.
I am able to connect to the remote database from inside JDeveloper 9.0.3 and execute some simple SQL statements.
The problem is when I try to run this applet on a web page to test it I get some exceptions.
with e.message()
access denied (java.util.PropertyPermission oracle.jserver.version read)
java.security.AccessControlException: access denied (java.util.PropertyPermission oracle.jserver.version read)
I know from within the IDE I assume the security settings are lax or non-exsistant.
any ideas?
Thanks,
Martin

Java applets can only access their host machine. If your database is located on a different server than the web server then you get these errors. To access a database located on a different machine you can use the so callled Applet - Servlet tunelling. You actually use a servelt as a proxy. The applet calls the servlet and the servlet accesses the database.
There is a lot of info on these issues in java.sun.com.
hope this helps!

Regards with Webdynpro Java in ESS

Hi,
i wanted to know whether we can use webdynpro abap in a J2EE server.
I have the issue that at the client, all the objects are customized and what i came to know that
we can use webdynpro only on the standard packages but not on the customized ones.
so here my issue is that can we use Webdynpro ABAP for the customized ones (objects)
if yes then how do we proceed further.
and how do use webdynpro ABAP in J2ee server
please reply me at the earliest possible

Web Dynpro ABAP is SAP's strategy to build Web Applications in ABAP environment.
Web Dynpro ABAP is run on ABAP Engine not on Java Engine. ECC 6.0 by default has the ABAP Web Application Server. You can develop Web Dynpro ABAP Applications in the ECC itself and can be integrated into Portal via iViews.
Web Dynpro Java is a tool to develop Web Applications in Java Environment. Jco is the medium through which it connects to R/3 system and calls the RFC Function Modules.
I hope it is clear.

Hi
If you want to try out using ADOBE Flash Islands with WDJ, you would need to download SAP CE 7.1 EhP1 trial version, if not done so already.
The following link may help you in building the WDJ component with Flash Islands..
The specified item was not found.
If you donot want to develop the Flex project you can download the .swf file provided by the SAP mentors:
