java - weblogic上下文查找错误: java. rmi.UnmarshalException:解码参数时出错

Question

我们的生产环境面临问题。我们在网上到处搜索，但没有找到任何答案。当从受管服务器 1 到管理服务器 2 进行 ejb 查找时，会发生此错误(下面的堆栈跟踪)。查找时使用虚拟 IP。它间歇性地、随机地发生。我们无法识别任何模式，如果尝试调用 ejb 两到三次，它就会成功通过。

环境详细信息:服务器:在java 1.5上运行的weblogic 10.0 MP1操作系统:solaris

如果需要任何其他详细信息，请回复。

用于查找的来源:

private TreControlRemote getController() throws Exception {
    Context context = null;
    Properties p = new Properties();
    TreControlHome treHome = null;
    TreControlRemote remote = null;
    ConfigurationLoader lAppLoader = null;
    try {
        mLog.debug("Entering");
        lAppLoader = PropertiesFileLoader.getInstance("context.properties");
        p.put(Context.INITIAL_CONTEXT_FACTORY, lAppLoader.getValue("INITIAL_CONTEXT_FACTORY"));
        p.put(Context.PROVIDER_URL, lAppLoader.getValue("PROVIDER_URL"));
        context = new InitialContext(p);
        mLog.debug("context : " + context.getEnvironment());
        remote = null;
        treHome = (TreControlHome) context.lookup("CONTROL");
        mLog.debug("Object --->>>>" + treHome);
        remote = (TreControlRemote) treHome.create();
        mLog.debug("Leaving");
    } catch (Exception ex) {
        mLog.fatal("Exception while getting remote", ex);
        ex.printStackTrace();
        throw ex;
    } finally {
        lAppLoader = null;
    }
    return remote;
}

该 url 是指向托管服务器 2 的虚拟 IP，它包含一个带有 jndi“CONTROL”的 ejb。问题是它在某些情况下成功，但随机失败并出现错误:

从 weblogic 日志中获取了下面提到的堆栈跟踪。这个错误是否与我们上面提到的问题有关？

任何帮助将不胜感激。

这里有一些附加信息..

问题是间歇性的，还是每次都会重现？如果问题是间歇性的，您知道它在什么条件下发生吗？它是间歇性发生的，我们无法观察到任何模式。

本地服务器或远程服务器上是否记录了任何其他错误/警告？我们在 weblogic 日志中看到很多连接拒绝错误

两台托管服务器是否位于同一域中？是

Answer 1

当您将 com.myclientcompany.server.eai.interactionspecimpl 的实例作为参数传递给你的ejb。 weblogic需要在ejb上下文下反序列化(unmarshal)对象，并且它需要解码所需的类。因此，如果您在 ejb-jar 文件中包含interactionspecimpl 类，那么您不需要在服务器类路径中包含这些类
