在SAP PI 7.5中，无法在参数化的Java Mapping中显示树状视图。

Question

我的工作是 parameterized java映射。当在Operation Mapping中测试时，它给了我们 错误 Unable to display tree view; Error when parsing an XML document (Premature end of file.) 而跟踪日志显示 Resource not found: META-INF/services/javax.xml.transform.TransformerFactory . 我们面临同样的问题 DocumentFactory 但我们写了下面的代码，它解决了这一问题。documentfactory 发出

 DocumentBuilderFactory factory = new com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl();

但我们仍然面临同样的错误 TransformerFactory. 请在下面找到整个代码，并请让我知道要做的修改。

请告诉我需要做哪些修改。谢谢 :)

Answer 1

检查说明 2669221 - Java 映射。未找到资源。META-INFservicesjavax.xml.parsers.DocumentBuilderFactory。

通过备注2669221应用这两行字。

javax.xml.parsers.DocumentBuilderFactory = com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
javax.xml.transform.TransformerFactory = com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

或者在调用工厂之前加上这两行字。

System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
System.setProperty("javax.xml.transform.TransformerFactory", "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
