But when i run the Sim,the message is:

What is the problem ,and how can i sovle this problem. Thank you.

Hi, thank you for raising this issue. The problem is that the Sim class when run cannot find the LogManager manager class from the log4j2 library. It all boils down to specifying the required classes correctly with -cp parameter when running java. In my opinion the easiest way is to put all 4 jars i.e.

• sapjco3.jar
• log4j-api-2.19.0.jar
• log4j-core-2.19.0.jar
• mfsplc.jar in a single directory. Then go to this directory and run the simulator with:
• java -Dlog4j.configurationFile=log4j2.xml -cp sapjco3.jar;log4j-api-2.19.0.jar;log4j-core-2.19.0.jar;mfsplc.jar pl.sapusers.mfsplc.sim.Sim S4H MFS.properties
• java -Dlog4j.configurationFile=log4j2.xml -cp sapjco3.jar;log4j-api-2.19.0.jar;log4j-core-2.19.0.jar;mfsplc.jar pl.sapusers.mfsplc.bridge.Bridge S4H MFS.properties

Let me know if that works for you.

Thank you for your help,now both bridge and Sim are working well.I have ran the Bridge and Sim succesfully,But i meet a new problem now,When I start the channel using /scwm/mon,the error happens in the console,as it is follow:

This problem has been sovled,the reason is that the access of port 7000 is not permited in my operating system. Now i cant start the channel succcesfully. Next, i will test the transmission and confirmation of wt. Thank you very much.

I'm glad the issue is resolved. Next time please open individual issues for each problem, i.e. one Github issue - one problem. This way it's easier for other users to follow the issues and their resolutions.
