Hello, Thanks for the reply, but it "seams" to do. Indeed, I've managed to generate a many-to-many relationship with seam-gen between two tables NAME1 and NAME2: The many-to-many relationship table should: - its name should be "NAME1_NAME2" - it has the right to have only 2 columns : a double primary key relying on the two foreignKey columns : FK1 and FK2 named as you want but with reference integrity constraints towards the primary key of the two tables : NAME1 and NAME2.
It has generated me the getters and setters of the list in each entity NAME1 and NAME2 : Expl : - The class NAME1 contains the function "public Set<NAME2> getName2s()" and its setter and - The class NAME2 contains the function "public Set<NAME1> getName1s()" and its setter and no entity has been generated for the table "NAME1_NAME2", that is right because it is a "utility table" and not a table reflecting a "business objet" to be persisted. The hibernate relationship has been created also : | @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) | @JoinTable(name = "NAME1_NAME2", catalog = "mycatalogname", joinColumns = { @JoinColumn(name = "NAME1_ID", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "NAME2_ID", nullable = false, updatable = false) }) | public Set<Name2> getName2s() { | return this.name2s; | } | | public void setName2s(Set<Name2> name2s) { | this.name2s = name2s; | } | I still have a problem in the following step : As the returned list is of type java.util.Set and not java.util.List, I do not (for the moment) manage to display this list in a rich:datatable : | <rich:dataTable var="name2s" | value="#{name1Home.instance.name2s}" | rendered="#{name1Home.instance.name2s != null}" | rowClasses="rvgRowOne,rvgRowTwo" | id="name2sTable"> | <h:column> | <f:facet name="header">id</f:facet> | #{name2s.id} | </h:column> | Caused by javax.servlet.ServletException with message: "/Name1Edit.xhtml: Property 'id' not found on type org.hibernate.collection.PersistentSet" javax.faces.webapp.FacesServlet.service(FacesServlet.java:256) org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) Caused by javax.el.ELException with message: "/Name1Edit.xhtml: Property 'id' not found on type org.hibernate.collection.PersistentSet" com.sun.facelets.compiler.TextInstruction.write(TextInstruction.java:48) com.sun.facelets.compiler.UIInstructions.encodeBegin(UIInstructions.java:39) org.ajax4jsf.renderkit.RendererBase.renderChild(RendererBase.java:280) If anyone can help me on this point.
