sdf or urdf to dae conversion problem

Hello

I am trying to convert a sdf to dae file and I have a problem with the conversion. The sdf file is for a robot and simtrans only converts the first part of the robot. I attached my sdf code over here. The only thing that i can guess of is the jointid. Because it shows:
2019-01-21 15:47:56 PC-name root[6415] INFO validating joint LJ1
2019-01-21 15:47:56 PC-name root[6415] WARNING jointId not set

I have tested the urdf file and I have the same problem. Would you please help me for solving this problem?
Thank You
