hibernate @manytomany mapping multiple keys

i'm perplexing map manytomany family between 2 tables, both carrying multiple primary keys

lsfoctb primary pivotal stoical : lsfoc_codsoc,lsfoc_codlsc,lsfoc_codfoc

lsfortb primary pivotal stoical : lsfor_codsoc,lsfor_codlsc,lsfoc_codfor

the list assign manytomany charge :

lsfcftb, : lsfcf_codsoc,lsfcf_codlsc,lsfcf_codfoc,lsfcf_codfor

so, hibernate denote mapping lsfoctb, i attempted :

@manytomany(targetentity = package.lsfoctb.class, cascade = { cascadetype.persist,
            cascadetype.merge })
    @jointable(name = "lsfcftb", joincolumns = {
            @joincolumn(name = "lsfcf_codlsc", referencedcolumnname = "lsfoc_codlsc"),
            @joincolumn(name = "lsfcf_codfoc", referencedcolumnname = "lsfoc_codfoc"),
            @joincolumn(name = "lsfcf_codsoc", referencedcolumnname = "lsfoc_codsoc") }, 
    inversejoincolumns = { @joincolumn(name = "lsfcf_codlsc", referencedcolumnname = "lsfor_codlsc"),
            @joincolumn(name = "lsfcf_codfor", referencedcolumnname = "lsfor_codfor"),
            @joincolumn(name = "lsfcf_codsoc", referencedcolumnname = "lsfor_codsoc") })

before getter.
but won't work...
the error, perplexing opening apart collection :

org.springframework.beans.factory.beancreationexception: blunder formulating bean name 'sessionfactory' tangible category route apparatus [beans-dao.xml]: bid init slight failed; nested difference org.hibernate.mappingexception: steady buttress mapping collection: package.lsfoctb.distantcollection column: lsfcf_codlsc

have already managed an hibernate mapping work manytomany charge ?
if so, wrong mapping ?
thank your assistance !
