Hi


this may occurs at the point you access a collection of a persistance object when session has closed. keep session open until you finished your job.

send your java codes to more details.

I got thesame problem, could you show me the way

public void setEnterSchoolCurrentContestant(Contestant1 enterSchoolCurrentContestant) {
this.enterSchoolCurrentContestant = enterSchoolCurrentContestant;
Hibernate.initialize(enterSchoolCurrentContestant.getCandidatetimes());
this.enterschoolCurrentCandidatetimes = enterSchoolCurrentContestant.getCandidatetimes();
Hibernate.initialize(this.enterschoolCurrentCandidatetimes.getAcademicyear());
this.enterschoolCurrentAcaYear =this.enterschoolCurrentCandidatetimes.getAcademicyear();
Hibernate.initialize(this.enterschoolCurrentCandidatetimes.getSemester());
this.enterschoolCurrentSemester = this.enterschoolCurrentCandidatetimes.getSemester();
}
