SAP Enterprise Connector Error - NWDS

Hello I have the following issue, I found the same problem in the eariler forums(no solution though) and pasting it here...
the content is copied from /thread/9971 [original link is broken]
Hi
I've installed the sneak edition of the NDS which is a part of the WAS 6.40 sneak preview. Everything seams to work just fine except for the proxy generation in a portal application using the SAP Enterprise Connector tool.(choose new>other>SAP connectivity-->SAP Enterprise Connector) I get to the point where I have to enter connection information's for a single server like Host name, system nr, client, etc...However when everything i filled out and I push next nothing happens. The process line in the bottom shortly fills but the same screen is shown.
Have anyone run into the same problem?
Best Regards
Ole Mose Nielsen
the problem I have is exactly the same. But say if I change the system number to '04' than I get an error - "connect to sap gateway failed".
Thanks,
Yasu

Hello some more information....
I have installed the ABAP 6.4 Sneak Preview SP11 (It works fine with the SAP GUI). I am trying to call Bapis from Java with the help of the proxies generated by "SAP Enterprise Connector". But the problem is that the "SAP Connection Wizard" does not progress any further after providing the R/3 system details(like hostname, sys number, client) and username/pasword. When I click the "Next Button" after providing the correct connection parameters it just stays there.
-->Would the license be a problem. I did not apply for the 90 day license yet, I wanted to do that once everything is working fine.
--> Should I do any additional configuration on the R/3 side.
--> Should I add any extra setting to the environment variable path.
Your help will be greatly apprecaited!!!
Thanks

Runtime error while using SAP Enterprise Connector in a J2EE Web Servlet

Hello,
I'm facing problems while trying to do a RFC call out of a Servlet.
I'm using Development Components (DCs) and my project setup is as follows:
Firstly I've created a DC of type J2EE/Web Module. This DC implements an absolutly simple servlet which has to do the RFC-Call.
The relevant code is:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   JCO.Client jcoclient = JCO.createClient("010", "DV*****", "***", "DE", "ovd***", "01");
   jcoclient.connect();
   Bapi_Flight_Getlist_Input input = new Bapi_Flight_Getlist_Input();
   input.setAirline("LH");
   SAPProxies_PortType myproxy = new SAPProxies_PortType();
   myproxy.messageSpecifier.setJcoClient(jcoclient);
   try {
      Bapi_Flight_Getlist_Output output = myproxy.bapi_Flight_Getlist(input);
      BapisfldatType_List list = output.get_as_listFlight_List();
      int listsize = list.size();
      for (int i = 0; i < listsize; i++) {
         BapisfldatType elem = list.getBapisfldatType(i);
         response.getWriter().print("Date: " + elem.getArrdate() + '\t' + "Arrive: " + elem.getArrtime());
   } catch (Exception e) {
      response.getWriter().print(e.toString());
   jcoclient.disconnect();
The proxy for the RFC Module "BAPI_FLIGHT_GETLIST" - in this case the classes around "SAPProxies_PortType" were generated by NWDS ("SAP Enterprise Connector" Wizard).
I had to manually add following DCs as "Used DCs" to get my DC built:
com.sap.aii.proxy.framework (default)
com.sap.aii.util.misc (default)
com.sap.mw.jco (default)
So far, so good...
As a J2EE/Web module DC can't be deployed I've created a second DC of type J2EE/Enterprise Application and referenced the first DC. This DC is also built fine and can be deployed.
But... When I call my servlet I get following Error Message on the web browser:
The request cannot be processed.
Details:
com.sap.engine.services.servlets_jsp.server.exceptions.ServletNotFoundException: Cannot load the requested servlet [LocalDevelopmentservletxxx.com/servlet/TestServlet].
Exception id: [000C295D60FB006F0000003600000EA8000461A05860B4BA]
I also had a look in the trace files:

I think it has something to do with the used DCs... but I don't know why the classes are not found after deployment. I also tried
to package the relevant jar-files from the used DCs into the EAR-File - but the I faced problems with the JCo
Thank you for any help.
Osman

Hi,
One thing that can be helpful is to add the references of the JAR files that you are adding as Used DC in the EAR.
This can be done by adding Library type References in the application-j2ee-engine.xml Deployment descriptor in the EAR project.
Following link will be helpful: http://help.sap.com/saphelp_nw70/helpdata/EN/83/82814282cfc153e10000000a1550b0/content.htm

Need help with the SAP Enterprise connector wizard at the NWDS

Hello,
I am trying to create new proxy using the SAP Enterprise connector at the Netweaver Developer Studio.
The problem is that at the 2nd stage I am unable to connect to the server. Can someone please explain me in details:
1. Which tab should I chose there: Load balancing server or single server?
2. Which parameters should I enter there and from where can I take them (uch as System number...)
I tried to enter my server's parameters but I couldn't connect.

Hi Roy,
It depends on what type of R/3 server you are connecting. Usually development & Quality assurance systems for R/3 are not load balanced. You can find it out from your Basis people that server you are connecting is load balanced.
If it is not load balanced then the select the single server and enter the following parameters.
1. Host Name: Server Name (or ip address)
2. System Number: (00)
If it is load balanced then fill out all the information on load balancing tab.
You only need to fill one of the tabs. thank you.

EJB Modul: SAP Enterprise Connector, configuring build path

Hello,
first of all I'm using SAP NW CE.
I created an 2 Development Components, an EJB Module and a Enterprise Application(EAR). In the EJB Module I use the SAP Enterprise Connector to generate Java Proxy Classes to do RFC calls.
In the EAR-DC I add in Properties-->J2EE Module Dependencies the needed jar-files. And in the EJB-DC I reference this.
When I don't work with DCs and I create a "normal" EJB and EAR project that is the way it works.
But with DCs I have a problem when I want to build the DC. I have this error:
package com.sap.aii.proxy.framework.core does not exist
So the build-process don't realize the J2EE Module Dependencies. How can I solve this problem?
Regards,
Armin

Did you mean the Development Infrastructure Perspective? If yes I don't find DC -> DC Metadata -> DC Definitino -> Right-click Used DCs -> Add Used DC... if I browse through my DC.
Apart from that I don't want to reference DCs as I write above. I want to reference only jar-files. Because the DCs com.sap.aii.proxy.framework, com.sap.aii.util..misc and com.sap.mw.jco are deprecated. And if I reference DCs I have to use this DCs to use the proxy classes made by the SAP Enterprise Connector. So I want to reference the jar-files where the needed source isn't deprecated.
By the way I use SAP NW CE.

Creating a WEB Service for SAP enterprise connector

Hi,
I am using the SAP enterprise connector plugin for Netweaver 04.
It generated me all the classes that I need for the BAPI.
It also generated me a Proxy class.
I want to create a service.
This is what I've done :
1) create a portal service.
2) create a methode in the service :
public Bapi_Companycode_Getdetail_Output execute_BAPI_COMPANYCODE_GETDETAIL(
Bapi_Companycode_Getdetail_Input arg1)
try {
return new MyProxy_PortType().bapi_Companycode_Getdetail (arg1);
} catch (Exception e) {
return null;
3) after I created a web service from the portal service.
Is it the right way ?
Thanks a lot.

Hi Marcin and everyone,
Thanks for the precious explanations.
I created a client and I have an exception.
1) I made a portal service from wsdl - client side.
2) I created a DynPage.
3) Here is the code :
IMyBAPI4Service client = (IMyBAPI4Service) PortalRuntime.getRuntimeResources().getService(
IMyBAPI4Service.KEY);
IMyBAPI4Service securedClient = (IMyBAPI4Service) client.getSecurisedServiceConnection(                 request.getUser());
//this is null.
if (securedClient.getURLEndPoint().getURL() == null) {
securedClient.setURLEndPoint(new URLEndpoint("http://<server>:<port>/irj/servlet/prt/soap/com.sap.portal.prt.soap.MyBAPI4Service?style=doc_lit"));
Bapi_Companycode_Getdetail_Input importParams =     new Bapi_Companycode_Getdetail_Input();
importParams.setCompanycodeid("0500");
Bapi_Companycode_Getdetail_Output exportParams = null;
securedClient.execute_BAPI_COMPANYCODE_GETDETAIL(importParams);
Do I have to use a secured client ? What is it ?
The exception is :
Problem at execution: SOAP Fault Error (java.lang.NoClassDefFoundError) : java.lang.NoClassDefFoundError
Thanks Marcin....

SAP Enterprise Connector

Hi Experts
I tried generating Proxy classes for first time for FlightAppList using SAP Enterprise connector by selecting Single Server option, I have installed SAP Management Console on the system having host name 'sap-server', the details i provided was as follows:
HostName:'sap-server'
System Number: 00
SAP Router:
User Account
Client : 001
LogonName: pradeep
Password: password
Language:ENG
but i get the error as
Connect to SAP failed
Error: Partner not reached
Do i need to do any settings on SAP Netweaver console.
Kindly let me know.

Configuring webasabap needs SAP security library which can be downloaded at sap market place, but it needs a license username password which i dont have.
I have only downloaded the trial version "SAPNW2004sJavaSP9_Trial" is there a way i can connect my java program to SAP database without having any license?

SAP Enterprise Connector and service....

Hi everyone,
After creating, via the plugin "SAP Enterprise Connector", a proxy pointing on a BAPI, how can I create a service for this (and a web service).
I know that you can create a web service directly using ABAP transaction se37. But our SAP version is quite old and we haven't this option.
Thanks for the help.

SAP Business Connector Error

Guys,
Do you know what this error in SAP Business Connector means:
Missing or Invalid Parameter:Sender
Any help would be appreciated.
Thanks,
Sathya

Now this is a broad question_
I guess you mean: IDOC handling
This means usually, that the Sender ID is not set up properly in the BC (Send/Reveice Rules). In case you don't have a 1:1 mapping, use the '*' for ALL.
Can you please give more specific information:
where is the Error (Log, Popup-message etc),
what is the context (BAPI CALL, IDOC etc)

Calling an RFC from an EJB over an Enterprise Connector

Hi all,
I would like to call an RFC enabled Function Modul (FuBa) from a BW-System over an EJB in a Web AS environment bei passing SAP Logon Ticket.
To achive this goal, i've generated proxy classes (Enterprise Connector) via NWDS .
If i call enterprise connector localy from an example class (See attachment), it works.
BUT
if I use the same Code within an EJB, bei correct deployment , it doesn't work. I become an exception, during to establish a connection
What is wrong here ?
What do i have to do in an a EJB-Environment to use an Enterprise Connector ?

Regards,
Nishita Salver

Dear Nishita,
I hope you have removed the older version of jdk before installing the new version of jdk. Also after un installation of NWDS, did you delete all the temp files and also the directories created during the original installation of NWDS. Also did you restart your system after the uninstallation of NWDS EHP1 and older jdk before reinstallation of the two softwares?
Regards,
Veera
P.S. The first thing you can try is restarting the PC and try resuming the installation, if it doesnt succeed, please remove all traces of NWDS and JDK, restart pc and then resinstall both of them.
