JCO - Application Server

Hi
I am trying to make a JCO connection through an application server (single server) instead of message server (load balanced).
I included the application Server in SLD administration.
When I reference this application Server in Webdynpro configuration manager, in JCO connection, all parameters seem to be ok, but I got the error message:
CIM_ERR_FAILED MAXLEN(2) violeted for property AppServNumber.
I filled application server number in the field labeled "number"....should I put this information in some another place too??
Any ideas?
Regards.

Hi Ronaldo,
I don´t know the solution of your problem but the easiest way to get your R/3 system data into SLD is by using SLD supplier bridge and (I think) transaction RZ70 in your R/3 system. When configured correctly the R/3 system sends its data automatically to the SLD server which registers the R/3 system then.
Have a look at Post-Installation Guide of SLD which is available at service marketplace.
Additionally you should know that you need a message server if your are working with Adaptive RFC for retrieving the meta data of your function modules.
In Web Dynpro Administrator you have to define to JCO destionations. One for meta data (message server) and another for model data (message or application server).
Does this help?

How To Populate Application Server Dropdown List In JCo Destination

Hi guys, I'm currently working on EP7 and just finished installing the ESS Business Package. The next step is to maintain the JCo Destinations in the Web Dynpro Console and here's where I got stuck. When I got to step 4.1 the field for the Application Server is a drop down list with no items in the list. How do you populate this list? Thanks in advance!

Figured it out! Maintain an Web AS ABAP Technical System in the SLD.

Use of JCo in JBoss Application Server

Hi All
does anyone know if the SAP JCo drivers are supported in other Application Servers (e.g. JBoss 6) ?
Thanks a lot in advance

The short answer is yes.
The longer answer:
As I am aware of, SAP does not guarantee that they work in application servers other than SAP WebAS per se, but I know that they work at least in Tomcat and Websphere. JCo does not include dependencies on the application server architecture and can also run locally with a Java application on your machine.
As JCo involves native code, there is a limitation on what Java/OS platform it is supported. For the current JCo 3.0, you may refer to SAP Note 1077727 for compatibility with your Java version and Operating System platform you run with JBoss.

Application server crashes when using JCO

Hi,
I am currently dealing with JCO Version 2.1.8.
For testing purposes, I want to receive data from a Remote Function Module existing in our SAP development system.
Therefore I created a simple Java servlet:
public class POA_EDS_Servlet extends HttpServlet {
   private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   response.setContentType("text/html");
   PrintWriter out = response.getWriter();
   out.println("<html>");
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
     response.setContentType("text/html");
     PrintWriter out = response.getWriter();
     String uri = request.getParameter("uri");
     JCO.Client connection;
     connection = JCO.createClient("200",
               "DAHMSMA",
               "EN",
               "vmw3063.wdf.sap.corp",
                              "00");
     try {
        connection.connect();
     catch (Exception ex) {
          ex.printStackTrace();
          System.exit(1);
After deploying and when running this servlet, the application server is crashing. That means I have to restart the server via Remote Desktop Connection.
Can anybode provide some help?
Regards
Marco

Any one can help me in this matter?
Thanks
Debraj Roy

Debraj,
in SXMB_MONI, go through the "Trace" header section of the message and find the exact point in which the exception occurs. Paste it here.
At a glance, it seems an RFC call that fails inside the mapping... Do you use JCo & UDF in the mapping to do some lookup/check in R/3?
Let me know.

Application Server Not apprearing in dropdown list

Hello ,
While creating JCo Connection , application server is not appearing in the connection wizard . SLD server settings are at place and running.

Hi,
Hope you are creating a JCo connecton through the content administrator. You can set the properties of the application server while creating the Application data connection type if you are having a single server connection.

Integration between EP & BW (with multiple application server)

Hello Experts,
We are configuring JCo Rfc Provider using visual administrator.
We have Successfully used Note No##Note 917950 - SAP NetWeaver 2004s:
Setting Up BEx Web,For Our Development & QAS BW & EP Server.(Single application Server)
But on our Production systems which have multiple application servers ( 3 each for EP & BW) at the step of creating RFC Creation we find that the RFC connection (JCO provider) only works when we specify the individual Apps server in the BW Host Field. We are not able to Specify the BW message server in the JCO Connection.
Kindly help us to resolve this issue.
With Regards,
Anshul

Hi Jim,
The reason that the documentation specifically spells out IBM Websphere is most likely because it was the application server that we developed and tested with at the time. The important requirement for this type of integration is that this server be an Intel based server running a Microsoft OS. The reason for this is because there are dlls with the Oracle IPM product that enable communication between the IPM functions and the JDE Business functions. If the Enterprise server for JDE is intel based then a JAS can exist on the same server, the dlls can be on that machine and the extra server is not required. This server is only required if the Enterprise server is not intel based. As far as your choice to use Oracle Application Server goes, I really have no basis to say if this works or not. My thought is that it shouldn't matter as long as the JAS server is an intel based, 32 bit server running a Microsoft OS. There are many other variables and lots of experience implementing this type of integration with JDE within the Oracle IPM consulting team. Give us a call if we can help.
Hope this helps,
Matt

Application server on a XI system

Hi Guys
We have installed an Application server on a XI system. Now we have a serious problem.
Now I see in Visual Administrator 2 Dispatcher and 2 Server. Basically The App server created his own Server in Visual Administrator. My Server 0_0 runs on port 50004. My Server 0_2 runs on port 50204. The JCo`s and everything is the same on the 2 Servers. Basically Server 0_2 clone Server 0_0.
The problem we have is: The primary Dispatcher that Xi is using is the one of the App server. When Xi starts running the files it is specifically looking for port 50204.
Can anyone please tell me where I can change this? So that the primary port 50004 can be used?
Thanks in Regards
S.W.

Hi,
If u want a frequent deletion this approach to delete a record from a file will havee unnecesary copy of records from one file to another and deletion of one file and renaming activities.
Instead what u can do is Add and field del_flag to ur record structure.
If u want to delete the record from a file just mark this del_flag as 'X'.
While processing u can have a loop like
loop at it_XXX where del_flag <> 'X'.
endloop.
This will logically delete the record.
When u r to finish the application at that time only perform this copying / deleting / and renaing activity
Hope this helps.
Cheers,
Nitin
