我正在尝试在我的android项目中使用jpos，我从互联网上下载了一个示例的fields.xml。我想知道为什么或者如何在调用GenericPackager函数时解决这个错误。

java.lang.Exception: org.jpos.iso.ISOException: java.lang.ClassNotFoundException: Didn't find class "org.apache.crimson.parser.XMLReaderImpl" on path: DexPathList[[zip file "/data/app/com.Activity-DQzzXo3E8QpU-bmLtFYx-Q==/base.apk"],nativeLibraryDirectories=[/data/app/com.Activity-DQzzXo3E8QpU-bmLtFYx-Q==/lib/arm, /system/lib, /vendor/lib]]

package com.Activity.ISO;

import org.jpos.iso.ISOException;

import org.jpos.iso.packager.GenericPackager;

import java.io.InputStream;

import javax.xml.parsers.DocumentBuilder;

public class PackISOMessage {


    public String buildISOMessage() throws Exception {

        try {
            // Load package from resources directory.
            //InputStream is = getClass().getResourceAsStream("fields.xml");

            InputStream xmlDoc = App.getContext().getAssets().open("fields.xml");

            //String file = "/fields.xml";
            GenericPackager packager = new GenericPackager(xmlDoc); //Here is debug error

            ISOMsg isoMsg = new ISOMsg();
            isoMsg.setPackager(packager);
            isoMsg.setMTI("0200");

            isoMsg.set(3, "000010");
            isoMsg.set(4, "1500");
            isoMsg.set(7, "1206041200");

            isoMsg.set(41, "12340001");
            isoMsg.set(49, "840");
            printISOMessage(isoMsg);

            byte[] result = isoMsg.pack();
            return new String(result);
        } catch (ISOException e) {
            throw new Exception(e);
        }
    }

    private void printISOMessage(ISOMsg isoMsg) {

        try {
            System.out.printf("MTI = %s%n", isoMsg.getMTI());
            for (int i = 1; i <= isoMsg.getMaxField(); i++) {
                if (isoMsg.hasField(i)) {
                    System.out.printf("Field (%s) = %s%n", i, isoMsg.getString(i));
                }
            }
        } catch (ISOException e) {
            e.printStackTrace();
        }
    }


}

这是我的fields.xml

我的包按钮配置：

代码语言：javascript
复制
ButtonPack.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PackISOMessage iso = new PackISOMessage();
                try {
                    String message = iso.buildISOMessage();
                    System.out.printf("Message = %s", message);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });

我在实例化打包程序之前添加了以下代码，从而解决了同样的错误：

代码语言：javascript
复制
System.setProperty("org.xml.sax.driver", "org.xmlpull.v1.sax2.Driver");
Field versionShown = org.jpos.util.Logger.class.getDeclaredField("versionShown");
versionShown.setAccessible(true);
versionShown.set(null, true);

然后，您可以实例化打包程序：

代码语言：javascript
复制
GenericPackager packager = new GenericPackager(xmlDoc);
