JSP - Need RFC

[Former Member]

Hi Experts,

In my NWDS, I have created an Enterprise Application project and Web module project. I have included two JSP pages called u2018first.jspu2019 and u2018second.jsp.u2019. When I navigate from main.jsp to result.jsp I need to call RFC with input values which are given by first.jsp page.

1. How to call the RFC?

I have searched for this in SDN some people suggests do these configurations in u2018Config.xmlu2019 file but in my project there is no config.xml file.

2. Do I need to create this file or is it already exists?

Please suggest me on thisu2026

Thanks in Advance.

Hi,

You need to use the SAP Java Connector (SAP Jco). Take a look at this thread for more information : [How to invoke a RFC with JCo|;.

"myproxy.messagespecifier can not resolved or is not a field" Please help me to solve this...

Thanks in advance

hello there,

Try to execute the BAPI directly from R3 using SE37 and check result. Do you please the necessary DLLs required for the JCO call

Can anyone tell me the answer for my second question in my initial post?

I have searched for this in SDN some people suggests do these configurations in u2018Config.xmlu2019 file but in my project there is no config.xml file.

2. Do I need to create this file or is it already exists?

Hi stars,

By default portalapp.xml file will be created. but you need to create config.xml file.

Hi Sunaina,

Thanks for your reply. I have created JCO connection for custom J2EE project using this link

http://help.sap.com/saphelp_nw04/Helpdata/EN/b6/55e3952a902447847066a0df27b0d6/content.htm

. I have a doubt, What are all steps to create JCO connection for B2C custom application? Do I have to follow the same steps mentioned on that link?

Hello there,

For JSP you need to make use of JCO. The specific jar files for this can be download from http://service.sap.com/connectors.

The best material on JCO coding is

Please let me know if you need any specific help
