      Hello Community,

       

      I am sorry for my bad english, but i try my best ;-)

       

      I am developing an application to learn Hibernate. I have got a class called "User" which contains n objects of class "Role" and class Role contains n objects of class "Rule". Everything is in lazyLoad mode.

       

      Here is class: "User"

      @Entity
      @Table(name="users")
      public class User implements Serializable 
      {
          @Id
          @Column
          private String userId;
          @Column
          private String userPassword;
          @Column
          private Date registrationDate;
          @Column
          private Date lastLogin;
          @Column
          private boolean online;
          @ManyToMany(targetEntity=Role.class)
          private List<Role> roles = new ArrayList<Role>();
          
          public void addRole(Role r) {
              Hibernate.initialize(roles);
              this.roles.add(r);
          }
          public List<Role> getRoles() {
              return roles;
          }
          public void setRoles(List<Role> roles) {
              this.roles = roles;
          }
          public String getUserId() {
              return userId;
          }
          public void setUserId(String userId) {
              this.userId = userId;
          }
          public String getUserPassword() {
              return userPassword;
          }
          public void setUserPassword(String userPassword) {
              this.userPassword = userPassword;
          }
          public Date getRegistrationDate() {
              return registrationDate;
          }
          public void setRegistrationDate(Date registrationDate) {
              this.registrationDate = registrationDate;
          }
          public Date getLastLogin() {
              return lastLogin;
          }
          public void setLastLogin(Date lastLogin) {
              this.lastLogin = lastLogin;
          }
          public boolean isOnline() {
              return online;
          }
          public void setOnline(boolean online) {
              this.online = online;
          }
      

       

      Here is class Role

       

      @Entity
      @Table(name="Roles")
      public class Role implements Serializable {
          @Column
          private String roleName;
          @Id
          @Column
          private String roleId;
          @ManyToMany(targetEntity=Rule.class)
          private List<Rule> rules = new ArrayList<Rule>();
          
          public String getRoleName() {
              return roleName;
          }
          public void setRoleName(String roleName) {
              this.roleName = roleName;
          }
          public String getRoleId() {
              return roleId;
          }
          public void setRoleId(String roleId) {
              this.roleId = roleId;
          }
          public List<Rule> getRuleList() {
              return rules;
          }
          public void setRuleList(List<Rule> ruleList) {
              this.rules = ruleList;
          }
          public void addRule(Rule r) {
              Hibernate.initialize(rules);
              this.rules.add(r);
          }
      

       

      And last one...class Rule

       

      @Entity
      @Table(name="rules")
      public class Rule implements Serializable {
          @Id
          @Column
          private String ruleId;
          @Column
          private String ruleName;
          @Column
          private String ruleValue;
          
          public String getRuleId() {
              return ruleId;
          }
          public void setRuleId(String ruleId) {
              this.ruleId = ruleId;
          }
          public String getRuleName() {
              return ruleName;
          }
          public void setRuleName(String ruleName) {
              this.ruleName = ruleName;
          }
          public String getRuleValue() {
              return ruleValue;
          }
          public void setRuleValue(String ruleValue) {
              this.ruleValue = ruleValue;
          }
      

       

       

      When I start my webservice and send an message to my service with the method "addRuleToRole"...I want that my Role add an existing Rule. I looked it up in my database there are an object of Role and Rule. But my service failed with the response:

       

      org.apache.cxf.interceptor.Fault: collection is not associated with any session

       

      Can anyone help me?
