Question

我一直在尝试从Java调用ColdFusion组件，然后执行以下操作：

https://helpx.adobe.com/coldfusion/developing-applications/using-web-elements-and-external-objects/integrating-jee-and-java-elements-in-cfml-applications/enhanced-java-integration-in-coldfusion.html

Java版本： 1.8.0_141

我在构建路径中添加了以下所需的jar：

cfmx_bootstrap.jar
cfusion.jar
javax.servlet.jsp.jar
javax.servlet-api-3.0.1.jar ( Servlet jars added as on running java program it was throwing ClassNotFound errors )

在此之后添加 Test.java ：

import coldfusion.cfc.CFCProxy;

public class Test {

    public static void main(String args[]) throws ClassNotFoundException {
        Test test = new Test();
        System.out.println(test.invoke().toString());
    }

    public String invoke() {
        String cfOp = null;
        try {

            // Instantiate CFC
            CFCProxy myCFC = new CFCProxy("D:\\practice\\cf_java.cfc", true);

            // Build arguments array
            Object[] myArgs = { "Java invocation!" };

            // invoke method from CFC. It returns a string.
            cfOp = (String) myCFC.invoke("getData", myArgs);

        } catch (Throwable ex) {
            ex.printStackTrace();
        }

        return cfOp;
    }
}

然后在 / JavaClass /

下添加 Test.class

的Application.cfc：

<cfcomponent>
    <cfset THIS.name = "CFTest">
    <cfset THIS.javaSettings = {
         LoadPaths = ["\JavaClass\"],
         reloadOnChange=true,
         watchInterval=10,
         reloadOnChange = true
    }>
</cfcomponent>

cf_java.cfc：

<cfcomponent>
    <cffunction name="getData" returntype="string">
        <cfargument name="msg" required="Yes">
        <cfreturn "I am alive!">
     </cffunction> 
</cfcomponent>

最后将Test.java作为java应用程序运行，我得到了以下内容：

java.lang.RuntimeException: CFCServlet must be initialized
    at coldfusion.cfc.CFCProxy.<init>(CFCProxy.java:121)
    at coldfusion.cfc.CFCProxy.<init>(CFCProxy.java:73)
    at Test.invoke(Test.java:15)
    at Test.main(Test.java:7)
Exception in thread "main" java.lang.NullPointerException
    at Test.main(Test.java:7)

我错过了什么吗？任何建议！

另外，来自Adobe Docs：

要调用CFC，ColdFusion类加载器必须是当前的类加载器。

任何人都可以解释一下或分享一些链接吗？

必须初始化CFCServlet
