我在weblogic应用程序上传文件时遇到问题。

文件上传器完成保存文件后，会出现以下异常：

在其他环境中，这个问题并没有出现，所以我认为它必须是JDBC驱动程序的一些配置，但我不确定我必须修改它。

调用struts

    private void adjuntarFichero()throws Exception {
    logger.debug("uploadFileName = "+uploadFileName);       
    if (uploadFileName!=null && !uploadFileName.equals("")) {
        HttpSession session = request.getSession();
        HashMap<Long,String> ficheros = (HashMap<Long,String>)session.getAttribute("ficheros");
        if (ficheros == null) ficheros = new HashMap<Long,String>();

        Fichero file = new FicheroImpl();
        file.setNombre(uploadFileName);
        file.setFichero(getBytesFromFile(upload));
        file = gestorFichero.guardarFichero(file);

        ficheros.put(file.getId(), uploadFileName);
        session.setAttribute("ficheros", ficheros);
    }        
}

错误发生在＆＃34; guardarFichero＆＃34;方法，调用DAO类来处理保存

公共抽象类gestorFichero 扩展org.springframework.orm.hibernate3.support.HibernateDaoSupport {

public Fichero guardarFichero (Fichero fichero){
    Debug.prec(fichero, "El fichero no puede ser nulo");
    return (Fichero)create(TRANSFORM_NONE, fichero);
}   
public java.lang.Object create(final int transform, final    com.aena.sgc.Fichero fichero)
{
    if (fichero == null){
        throw new IllegalArgumentException("Fichero.create - 'fichero' can not be null");
    }
    this.getHibernateTemplate().save(fichero);
    return this.transformEntity(transform, fichero);
}

最后我发现这是问题。

它与驱动程序类有关。最初我们将数据源配置为使用XA驱动程序 oracle.jdbc.xa.client.OracleXADataSource ，每当我们完成上传文件时，都会抛出异常。

一旦我将驱动程序更改为 oracle.jdbc.OracleDriver ，这些错误就会消失。

保存blob时连接已关闭
