package ctrl;

公共类TestBean {

TestDao testDaoLocal;

private CodeTce codeTce = new CodeTce();

public void CreateTce() {

}


public void createEmployee() {
    testDaoLocal.ajouter(codeTce);

}
public CodeTce getCodeTce() {
    return codeTce;
}


public void setCodeTce(CodeTce codeTce) {
    this.codeTce = codeTce;
}
