Java Stack on R3 system to connect to EP server ?

[Former Member]

Hi all,

For JCO Destination to use in Webdynpro application ,we make Technical System Landscape using

Web AS ABAP to connect to R3 based system..

I have made WD applications using aRFC to utilize R3 based BAPI in EP..But in some system of R3

i am not able to connect to R3 and use BAPI.

I need to know wether any JCO RFC Provider Service in R3 system has to installed to connect to java calls.

Is there any Java stack or any Java patch ups has to be installed in R3 system,

for proper SAP GATEWAY BRIDGE between R3 based system like(R3,CRM,SRM,BI-BW) and

EP's J2EE engine.

Waiting for reply

Hi,

once you make any call from webdynpro that will first go to the j2ee and through the jcos it will conect to the ABAP engine, then it will get u the data from R/3

Hi,

in teh WAS we have both the stacks JAVA and ABAP,

the logical system required to connect to the abap stack from java stack,

while creating of JCO you need to specify the JAVA name and ABAP engine name which declared under the SLD, as web as JAVA and Web As ABAP.

check in the SLD that Web as JAVA system and webAs ABAP system names,

after the come to your logical system and check weather the name of java and abap systems are given correctly or not.

make sure that the meta data logical system you have to give correct username and password, but in model data we have to give th eusername, otherwise both the case can work.

may be help for u,

Cheers,

Hi

1) In the SLD backend (R/3) system should be accessible.

2) JCO internally connects to above SLD. Here JCO should be tested suceesfully.

3) RFC or BAPI should be renote enabled.

Hi sridhar thanx for the reply..

I am clear about points 2 & 3.

But about point 1) In the SLD backend (R/3) system should be accessible.

U r rite SLD shud connect R3 to have RFC enalbled coneection to the this system..

But my doubt is that.., is their any java stack also present in the R3 system which initiates or acts to this SLD connection.

i have heared about RFC provider..is it java stack enabled which acts to the call from SLD connection pool..

Hi

As the present WAS contains both Java and Abap Stack,connections between the both stacks can be maintained.

For your information this can be checked in R/3 with Tcode SLDCHECK.

Thanks and Regards,
