Question

我有两个需要解析的XSD文件。加上一个带内联架构的wsdl文件。我正在使用XSOM来解析所有三个文件。 “XSD”文件被正确解析。但是，当我尝试从WSDL文件转换内联架构时，我得到以下异常。

带有内联模式文件的BPEL WSDL如下所示：`

//我正在使用此XSOM代码进行转换。我从XSOM用户指南中获取了这个

TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer(new StreamSource(new File("wsdl2xsd.xsl"));

ContentHandler xsomHandler = parser.getParserHandler();

// run the transformation and feed the result to XSOM
 t.transform( new StreamSource(new File("test.wsdl")),new SAXResult(xsomHandler));

  XSSchemaSet sset = parser.getResult();

// The style sheet is taken from previous post. It should extract the schema information //out of the provided WSDL.

可能是什么原因？感谢您的任何建议
