如何在远程WebSphere上的JNDI查找期间解决sun/io/MalformedInputException

Question

我使用WebSphere 8.5托管我的应用程序并在应用程序服务器上配置了一些JDBC资源。 另外我开发了一个使用瘦客户端运行时库的客户端应用程序。 当以下列方式进行JNDI查找：

env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory"); 
env.put(Context.PROVIDER_URL, "corbaloc:iiop:serv:2809"); 
Context initialContext = new InitialContext(env); 
DataSource ds = (DataSource) initialContext.lookup("cell/node/servers/server/MYDB"); 

以下异常引发：

Answer 1

如果你想使用Oracle JDK 8.0和IBM WebSphere，试图取代“ibmorb .jar'放到你的类路径中（使用新的java.nio.charset.MalformedInputException类）。

你可以在这里找到：

1. 下载IBM JDK 8.0（https://www.ibm.com/developerworks/java/jdk/java8/）;
2. 将获取的压缩包解压缩到一个文件夹（默认为eclipseDevelopmentPackage）;
3. 复制 'ibmorb.jar' 从以下路径：/eclipseDevelopmentPackage/ibm_sdk80/jre/lib/ibmorb.jar

希望这些帮助。

Answer 2

对于Sterling Commerce代理（带有JDK 8的Sterling 9.5），启动代理/集成服务器时可能会遇到以下异常。

原因：在JDK 8中，MalformedInputException被移动到另一个包，而英镑仍然期望在相同的包装中抛出此错误。

解： 以从以前的Java版本（1.6或1.7），其中sun.io.MalformedInputException仍然在相同的封装中英镑的rt.jar期望并做第三方的安装。

It works :)
