SAP GUI

[Former Member]

Hello!

Can I use the SAP GUI to access SAP Application Server?

If yes, how?

I want to login, but it failed everytime with message 10061 !

Hello Gerd,

the Sneak Preview Edition of Web Application Server contains only the Java stack and does not offer support for SAP GUI. This will change for Web AS 6.40.

Hi,

You can check the contents of SAP DB with SQL Studio.

Server: localhost

Database: C11

User: SAPC11DB

Password: sap

Thank you! I have with SQL Sudio access to SAP DB now!

But another error occurred when I want to run the webdynpro application accessing abab functions "Flights" from the Tutorial "creating a webdynpro application accessing abab functions ".

I can see the first site and can enter the departure city and the arrival city and press search.

But then this error message pop-up:

Hi Gerd,

you have first to create tables with the data dictionary and it is possible to access those tables. However, as this would not be a three tier approach, it is not supported by the tools to do this directly - remember we use this on our own and any tool that would make up a two tier application may result in an SAP application that works as such.

For now it is also not quite easy to write accessing EJB's and then connect them to web dynpro.

The easiest way in the version you have is to write beans, get them webservice interfaces and hang those into web dynpro.

All else is plain JDBC code.

Regards,

Benny

Well, first should have read the rest of the thread...

This is clearly a problem with your connection to the RFC system. you have not replaced the string "hostname" in the code you are using. You have to name it - well, ho it's named of course.

Hello.

I've got a problem similar to the one posted in this part of the forum.

I'm trying to connect an SAP BW 3.0b UNIX server, that is not placed in my LAN.

We've opened the right TCP/IP ports, in particular 3200 and 3300.

No problems at all if I use SAPGUI connection to enter the Administration Workbench (port 3200), so we can say that the basic communication between the two LANs is configured well, WITHOUT using SAP Router.

But if I try to use Business Explorer client tools, such as Analyzer, I encounter the classic message:

-

---

Connect from SAP gateway to RFC server failed.

Error Group

RFC_ERROR_COMMUNICATION

Message

Connect from SAP Gateway to RFC server failed

-

Then I click on Details button:

-

---

Connect_PM GWHOST=xxx.yyy.www.zzz, GWSERV=sapgw00, ASHOST=xxx.yyy.www.zzz

LOCATION SAP-Gateway on host [Internal Hostname] / sapgw00

Do you think it's a problem of the SAP Gateway configuration? Where have I to put my attention?

Please, note that the message shows both the [Internal Hostname] and the [External] one ... but I don't think that this is the problem...Is the NATting supported?

Thank you very much!
