尝试运行ST312_TestMain类时，线程“ main”中的异常java.lang.ExceptionInInitializerError

Question

I am trying to call "getOrderList" from the ST312_TestMain class. I am getting the java.lang.ExceptionInInitializerError for the below mentioned class.

package com.Main;

import org.w3c.dom.Document;
import com.yantra.ycp.core.YCPContext;
import com.Main.XMLUtil;
import com.Main.SterlingUtil;

public class ST312_TestMain {
    public static void main(String[] args) throws Exception {

        String ServiceName = "getOrderList";
        String sServiceFlag = "N";
        Document dTemplate = null;
        //ServiceName = "SendDN";
        //sServiceFlag = "Y";
        Document inputXML=null;
        inputXML = XMLUtil.getDocument("<Order OrderHeaderKey='201407181105267340509' />");
        //inputXML = XMLUtil.getXmlFromFile("src/Test.xml");
        dTemplate = XMLUtil.getDocument("<Order OrderHeaderKey='' OrderNo=''/>");
        if (args.length == 3) {
            ServiceName = args[0];
            sServiceFlag = args[1].equals("Y") ? "Y" : "N";
            inputXML = XMLUtil.getXmlFromFile(args[2]);
        } else {
            System.out
            .println("Usage: TestMain <API/Service Name> <API/Service(N/Y)> <Input XML File>");
            System.out
            .println("No Input received using preset XML to call preset Service");
            System.out.println("Service Name=" + ServiceName);
        }
        ***YCPContext env = new YCPContext("admin", "admin");***
        System.out.println("Input XML \n" + XMLUtil.getXmlString(inputXML));

        try {           
            Document outputXML = null;
            if ("Y".equals(sServiceFlag)) {
                outputXML = SterlingUtil.callService(env, inputXML, ServiceName, null);
            } else {
                outputXML = SterlingUtil.callAPI(env, inputXML, ServiceName, dTemplate);
            }

            env.commit();
        } catch (Exception ex) {
            ex.printStackTrace();
            System.out.println("Service Invocation Failed");
        }

    }

}

The exception is as follows:

Usage: TestMain <API/Service Name> <API/Service(N/Y)> <Input XML File>
No Input received using preset XML to call preset Service
Service Name=getOrderList
log4j:WARN No appenders could be found for logger (com.yantra.ycp.core.YCPContext).

Please help me on this problem, since I am not sure how to handle the YCPContext object. ("YCPContext env = new YCPContext("admin", "admin");"). Thanks in advance.

Answer 1

Request support from IBM about this.

No matter what mistakes you may have made configuring it (if any), the Sterling code should not be throwing an NPE at you.

Answer 2

If you are testing in local using main() method, then you should comment all the lines where you are using environment varilable. For your code its env variable.

Answer 3

可能您不会在项目构建路径中添加数据库驱动程序jar。例如，对于DB2数据库，必须添加db2jcc.jar；对于Oracle数据库，必须添加ojdbc.jar。
