When we tried to make WebService calls via php we found that some of the parameters are mandatory even if they are constants in the database. To prevent that we have to send empty parameters, i changed the minOccurs of TableName, RecordID and Action to 0 and regenerated the idempiere-xmlbeans.jar. Also i changed the Filter of ModelGetList to minOccurs=0.
