Question

我正在使用jpos库构建一个简单的电子购买财务消息，我使用通用打包器来打包我的消息字段，问题发生在字段48，即TLV字段。

以下是字段48的打包参数。

        <isofieldpackager id="48"
            name="Additional Private Data" 
            length="999"

    ISOMsg authISOMsg = new ISOMsg();

    // To be used in header

上面的主要代码表示包含某些字段的Financial msg，我在字段48 时出现的问题。

以下错误会引发以下异常。

    Nested:org.jpos.iso.ISOException: Error reading deploy\packager\basic-packager.xml (org.xml.sax.SAXParseException; systemId: file:basic-packager.xml; 
    lineNumber: 114; columnNumber: 64; Attribute "tagMapper" must be declared for element type "isofieldpackager").

Answer 1

您似乎需要使用generic-subtag-packager.dtd来验证您的xml打包程序定义。

您可以将该文件复制到与xml相同的目录中，并将doctype定义替换为此文件：

<!DOCTYPE isopackager SYSTEM "generic-subtag-packager.dtd">

我希望这能解决你的问题。
