HELLO

WHAT IS JCO?

Hi Vijay,

If you are developing Database applications, normally in any language you will create a connection to the database from your application. In SAP there is a pool of conections available ready to use. These connections will be already created by the admin. The developers can use whatever connections they need, as per their requirement. These connections are used to connect to the backend(BAPI or DataBase) of the application. These are called Java Connections or JCO.

Search in the forum, by giving the search text as "<b>JCo</b>", You will get lots of threads related to your query, Which will be surely helpfull to you.

Regards,

Prabhakar.

Hi viju..

See this links..

<a href="https://www.sdn.sap.com/irj/sdn/wiki?path=/display/wdjava/theJavaConnector(Jco),Enterprise+Connector&">JCO an Introduction</a>

<a href="http://help.sap.com/saphelp_nw04s/helpdata/en/3a/3b1b40fcdd8f5ce10000000a155106/content.htm">Creating JCO</a>

<b>JCO Connectivity to RFCs..</b>

Each WebDynpro application that connects to RFCs has to maintain RFC Connections. The general steps for handling RFCs are as follows:

1.Create WebDynpro Project

2.Import RFCs using Adaptive RFC Model

3.Specify the Model name, package

a)Specify the "Default Logical Name for model instances" and "Default logical names for RFC metada"

b)Specify the backend connectivity details like hostname, system number, client, logon userid,password

c)Select the RFCs you want to import

d)Modify the WebDynpro project/application as per your requirements

4)Go to WebDynpro Content Administrator (http://<server_host>:50000/webdynpro/dispatcher/sap.com/tc_wdtools/Explorer) and configure the JCO connections (created in step 1.2) which were created for your project when you imported the Adaptive RFC Model.

5)Check and ensure that your JCO connections are working.

Hope this will helpful for u..

Hi,

JCo Stands for java connector. Interfaces to communicate - RFC for SAP & JCo for Java.

SAP Java Connector (SAP JCo) is a middleware component that enables the development of SAP-compatible components and applications in Java. SAP JCo supports communication with the SAP Server in both directions: inbound calls (Java calls ABAP) and outbound calls (ABAP calls Java).

SAP JCo can be implemented with Desktop applications and with Web server applications.

SAP JCo is used as an integrated component in the following applications:

· SAP Business Connector, for communication with external Java applications

· SAP Web Application Server, for connecting the integrated J2EE server with the ABAP environment.

SAP JCo can also be implemented as a standalone component, for example to establish communication with the SAP system for individual online (web) applications.

Cheers,

JO

JCo is the java connector. It is a bunch of java classes written by SAP which help you in connecting a java application to your backend ABAP systems(and vice versa).
