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

我使用WebSphere 8.5来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。 我还使用瘦客户端运行时库开发了一个客户端应用程序。 以下列方式执行JNDI查找时：

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"); 

引发以下exception：

Answer 1

如果您想将Oracle JDK 8.0与IBM Websphere一起使用，请尝试将类路径中的“ibmorb.jar”替换为更新的（使用新的java.nio.charset.MalformedInputException类）。

你可以在这里找到它：

1. 下载IBM JDK 8.0（ https://www.ibm.com/developerworks/java/jdk/java8/ ）;
2. 将获取的存档解压缩到一个文件夹中（默认情况下为eclipseDevelopmentPackage）;
3. 从以下路径复制’ibmorb.jar’：/eclipseDevelopmentPackage/ibm_sdk80/jre/lib/ibmorb.jar

希望这些帮助。

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exception。

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

解决方案 ：从之前的java版本（1.6或1.7）中获取rt.jar，其中sun.io.MalformedInputException仍然与Sterling期望的包在同一个包中，并执行jar的Thirdparty安装。

有用 ：）
