我有一个在jsf 1.2中开发的应用程序，富有面孔3. Oracle 11gR2正在持有架构。部署在Websphere 7.应用程序集中部署，多个用户通过WAN访问它。问题是......突然间数据输入停止了...... Websphere日志给了我以下内容： - 当我在websphere上重启应用程序时，数据输入再次开始，然后再次任意停止。

EmployeeDetail的hbm文件在
下面<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="org.dao.EmployeeDetail" table="EMPLOYEE_DETAIL">
<id name="id" type="long" column="EMPLOYEE_ID">
<generator class="increment"></generator>
</id>
....
</class>
</hibernate-mapping>
插入功能如下： -
…
EmployeeDetail empDet = new EmployeeDetail();
session = sessionFactory.openSession((Interceptor)localInterceptor.get());
session.setFlushMode(FlushMode.COMMIT);
Transaction transaction = session.beginTransaction();
try {
empDet.setEmpName (empDetBean.getEmpName());
….
session.save(empDet);
transaction.commit();
session.flush();
} catch (Exception e) {
transaction.rollback();
e.printStackTrace();
} finally {
session.close();
}
请建议我采取措施。到目前为止，我已经在Websphere中尝试了不同的设置，如会话管理和数据源连接。同样，在代码中对hibernate会话应用了严格的检查。关闭会话，我明确打开它们但没有成功。
提前致谢。
