本文解释了为何不应将EJB类接口直接放入Web应用的lib目录下，详细阐述了Web应用类装载器与EJB类装载器之间的交互过程，以及将EJB接口置于Web应用lib目录可能导致的类型冲突问题。

Local is not bound说这个Local没有边界。

实际上就是说它认为你并没是一个本地接口，

出现这个原因是因为我没有把那个HelloWorldBean这个类文件导入进去。

为什么我们不用将EJB的类接口放入到Web应用的lib下面呢？

因为加载Web应用的类装载器时，如果没有寻找到这个接口时候它会交给EJB的类装载器进行处理。

而EJB应用已经加载到了WEB应用中了，所以这个就可以加载上了。

如果把EJB接口放在了WEB应用户的lib 下面的时候那么在有些情况下还会造成类型冲突的情况。

由于 K8s LocalPV 的使用限制无法满足生产需求，因此就需要寻找替代方案，好在已经有人实现了更强大的 LocalPV 存储方案：OpenEBS LocalPV。OpenEBS 官网。OpenEBS 可以将 K8s 工作节点上的任何可用存储转换为本地或分布式（也称为复制）持久卷。OpenEBS 最初由 MayaData 构建并捐赠给 CNCF，现在是 CNCF 沙盒项目。

Linux 上IPv6 udp套接字在板子上总是出现网络不可达，在主机上只有发送缓存<40字节才 能发送，41个字节的都会出现网络不可达。 问题描述： 最开始只发现了再主机上可以跑（测试数据<40字节），然后移到板子上（由于需求，在 板子上测试的时候就直接测试60字节数据，然后就发现不通，但是当时没注意到这个差别）而且打印系统返回的错误“网络不可达”，就以为是板子的IPv6配置或是板子对v6套接字的支持问题。 存在问题代码 /* * IPv6套接字编程 */ #include <sy

The import statement import_stmt ::= "import" module ["as" name] ( "," module ["as" name] )* | "from" relative_module "import" identifier ["as" name] ( "," identifier ["as" name] )* | "from" relative_module "import" "(" identifier ["as" name] ( "," identifier ["as" name] )* [","] ")" | "from" module "import" "*" module ::= (identifier ".")* identifier relative_module ::= "."* module | "."+ name ::= identifier The basic import statement (no from clause) is executed in two steps: find a module, loading and initializing it if necessary define a name or names in the local namespace for the scope where the import statement occurs. When the statement contains multiple clauses (separated by commas) the two steps are carried out separately for each clause, just as though the clauses had been separated out into individiual import statements. The details of the first step, finding and loading modules are described in greater detail in the section on the import system, which also describes the various types of packages and modules that can be imported, as well as all the hooks that can be used to customize the import system. Note that failures in this step may indicate either that the module could not be located, or that an error occurred while initializing the module, which includes execution of the module’s code. If the requested module is retrieved successfully, it will be made available in the local namespace in one of three ways: If the module name is followed by as, then the name following as is bound directly to the imported module. If no other name is specified, and the module being imported is a top level module, the module’s name is bound in the local namespace as a reference to the imported module If the module being imported is not a top level module, then the name of the top level package that contains the module is bound in the local namespace as a reference to the top level package. The imported module must be accessed using its full qualified name rather than directly The from form uses a slightly more complex process: find the module specified in the from clause, loading and initializing it if necessary; for each of the identifiers specified in the import clauses: check if the imported module has an attribute by that name if not, attempt to import a submodule with that name and then check the imported module again for that attribute if the attribute is not found, ImportError is raised. otherwise, a reference to that value is stored in the local namespace, using the name in the as clause if it is present, otherwise using the attribute name Examples: import foo # foo imported and bound locally import foo.bar.baz # foo.bar.baz imported, foo bound locally import foo.bar.baz as fbb # foo.bar.baz imported and bound as fbb from foo.bar import baz # foo.bar.baz imported and bound as baz from foo import attr # foo imported and foo.attr bound as attr If the list of identifiers is replaced by a star ('*'), all public names defined in the module are bound in the local namespace for the scope where the import statement occurs. The public names defined by a module are determined by checking the module’s namespace for a variable named __all__; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in __all__ are all considered public and are required to exist. If __all__ is not defined, the set of public names includes all names found in the module’s namespace which do not begin with an underscore character ('_'). __all__ should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module). The wild card form of import — from module import * — is only allowed at the module level. Attempting to use it in class or function definitions will raise a SyntaxError. When specifying what module to import you do not have to specify the absolute name of the module. When a module or package is contained within another package it is possible to make a relative import within the same top package without having to mention the package name. By using leading dots in the specified module or package after from you can specify how high to traverse up the current package hierarchy without specifying exact names. One leading dot means the current package where the module making the import exists. Two dots means up one package level. Three dots is up two levels, etc. So if you execute from . import mod from a module in the pkg package then you will end up importing pkg.mod. If you execute from ..subpkg2 import mod from within pkg.subpkg1 you will import pkg.subpkg2.mod. The specification for relative imports is contained within PEP 328 . importlib.import_module() is provided to support applications that determine dynamically the modules to be loaded.

1. 打开%JBOSS_HOME%\server\default\deploy\hornetq目录， copy hornetq-configuration.xml和hornetq-jms.xml 到你的项目的META-INF目录下，以保证在编译后这2个文件会被打包到EAR的META-INF中。 2. 修改hornetq-jms.xml，将里面原来的内容清空，加上你自己的Queue即可。
