In my code I am using two ManytoOne mappings as follows:

@JoinColumn(name = "Prompt_id", referencedColumnName = "Id", nullable = false)
@ManyToOne(optional = false)
private Prompt promptid;
@JoinColumn(name = "Variable_id", referencedColumnName = "Id", nullable = false)
@ManyToOne(optional = false)
private Variable variableid;

Prompt and Variable are tables with PK as Id in both. I am using them in a CallFlowMaster entity where Prompt_id and variable_id fields are FKs referencing Prompt and Variable PKs respectively.
While starting server I get following execption:
Caused by: org.hibernate.MappingException: Unable to find column with logical name: Id in org.hibernate.mapping.Table(Prompt) and its related supertables and secondary tables

Hi,
Sounds like you miss to map table Prompt or the column Id has another name in your mapping.
Hope it helps
