javax.naming.NoInitialContextException:无法使用哈希表中指定的工厂创建InitialContext

Question

我有一个小程序,它只是在非托管环境中创建初始上下文,即在容器外部.我一直在使用Websphere 7.0.我编写了以下程序来与使用corba url在WAS 7上运行的应用程序建立连接,

package snippet;

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;

public class test {
    public static void main(String[] args) {
        try {
            // create initial context
            Hashtable env = new Hashtable();
            env.put(Context.INITIAL_CONTEXT_FACTORY,
                    "com.ibm.websphere.naming.WsnInitialContextFactory");
            env
                    .put(Context.PROVIDER_URL,
                            "corbaloc:iiop:1.0@x1devapp63.dev.freightliner.com:2809/NameService");

            InitialContext ctx = new InitialContext(env);

            System.out.println(ctx);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }
} 

我创建了runnable jar并使用下面给出的shell脚本执行,

#!/bin/sh

WAS_ROOT_PATH=/application/WebSphere/AppServer
SCHEDULER_JAR=/application/apps/JobScheduler/testJNDI.jar
SCHEDULE_FILE=/application/apps/JobScheduler/schedule.xml
. "$WAS_ROOT_PATH"/bin/setupCmdLine.sh
CLASSPATH="$MQLIB":"$WAS_CLASSPATH"
"$JAVA_HOME"/bin/java -classpath "$CLASSPATH" -jar "$SCHEDULER_JAR"

跑步的我一直面临着异常,

$ testJNDI.sh
javax.naming.NoInitialContextException: Failed to create InitialContext using factory specified in hashtable {java.naming.provider.url=corbaloc:iiop:1.0@x1devapp63.dev.freightliner.com:2809/NameService, java.naming.factory.initial=com.ibm.websphere.naming.WsnInitialContextFactory} [Root exception is java.lang.NullPointerException]

Caused by: java.lang.NullPointerException
        at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:235)
        ... 5 more

我遇到了上述问题,但我无法理解为什么会发生这种情况.

请尽量让我从上面的问题中解脱出来.

不要忘记将thinclient-jar包含在buildpath中.您将需要它们从独立客户端进行jndi查找.

%WAS_HOME%/ runtimes是可以找到它们的地方.
