Access a JCo dest define in the Web Content Administrator

[Former Member]

I have got a J2EE application developed on NDS and i want to access and use a JCo destination defined in the Web Dynpro Content Administrator as a Web Dynpro application done.

First: is it possible or not ?

and if yes please tell me how ?

Cheers,

Eric Gourdou.

Hi Eric,

Yes, it's possible. Check <a href="http://help.sap.com/saphelp_nw04/helpdata/en/35/42e13d82fcfb34e10000000a114084/frameset.htm">this</a> out.

Hi Vlad,

it's not exactly what i want but i found this:

http://help.sap.com/saphelp_nw04/helpdata/en/25/19e7752be1c8459258a072d87e3a34/content.htm

and precisely what i expect:

The SLD enables you to specify the JCo client connection.

The following source code example can be used for accessing a configured JCo client connection:

WDJCOClientConnection client =

WDSystemLandscape.getJCOClientConnection(“myJCOClient”);

But it's not enough for me: i can have got a specified configured JCo client connection from the Web Dynpro content admin but how can i get back all the elemements of this connection: login, paswword, ... or it's possible to use (call) it as is directly in my Java code ?

Cheers,

Eric.

Hi Eric,

The following code enables you to get the configured JCo Connection.

IWDJCOClientConnection client =

WDSystemLandscape.getJCOClientConnection(“myJCOClient”);

If you want to get the User name/Password details, you can use the "IWDJCOClientConnection" to get the details.

//Getting the User name

String strUser = client.getUser();

//Getting the Password

String strPassword = client.getPassword();

If you would like to execute an RFC/BAPI, you can achieve it through the JCO.Client.

//Getting the JCO.Client

JCO.Client clientJCO = client.getClient();

Hope this is helpful for you.

Hi

I am trying access the similar thing as stated above. Can you please tell me where to get jar files to compile my code for using these classes

IWDJCOClientConnection

WDSystemLandscape

I could not compile there code as I could not find which jar to add apart form sapjco.jar.

Thanks in advance

Hi, we're trying the solution described above.

The application cannot be deployed on the WAS due to the following call:

WDJCOClientConnection client =

WDSystemLandscape.getJCOClientConnection(“myJCOClient”);

Here is the exception thrown by the deployment service:

server ID 8240151:com.sap.engine.services.deploy.exceptions.ServerDeploymentException: Application xxx cannot be started.

Reason: it has hard reference to resource tc_wdwebdynpro with type service, which is not active on the server.

Do you have any information on how to activate the service or how to reference the jar in the J2EE application.

By trying to define the service with a weak reference, the deployment works but a ClassNotFound exception is thrown.

Pierre,

Did you ever find a solution to your ClassNotFound exception?

[Former Member]

Hi Pierre!

I fixed this prob:

when you use add reference and tc/wd/webdynpro, you get this exception. This hapens because at buildtime the service is tc/wd/webdynpro and at runtime it is just webdynpro.

you must set the reference in application-j2ee-engine.xml:

<reference reference-type="hard">

<reference-target provider-name="sap.com" target-type="service">

<b>webdynpro</b>

</reference-target>

</reference>

instead of

<reference reference-type="hard">

<reference-target provider-name="sap.com" target-type="service">

<b>tc/wd/webdynpro</b>

</reference-target>

</reference>

Cheers!
