如何在远程WebSphere上的JNDI查找期间解决sun / io / MalformedInputException（ora-04052在查找远程对象）

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。我还使用瘦客户机运行时库开发了一个客户机应用程序。以以下方式执行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");

引发以下异常：

答案1

如果要在IBM Websphere上使用Oracle JDK 8.0，请尝试将类路径中的“
ibmorb.jar”替换为较新的类（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. 将获得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。
