JAXB「語法未指定」

Question

我嘗試從由Netbeans的一個xsd JAXB類，但即時得到

C:\datos\NetBeansProjects\RegistradoresWSSERCON\nbproject\xml_binding_build.xml:15: grammar is not specified 

相對於代碼道：

<xjc destdir="build/generated/jaxbCache/ACK" catalog="catalog.xml"> 

這是XSD我嘗試使用：

<?xml version="1.0" encoding="utf-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wmh="http://www.wmhelp.com/2003/eGenerator" elementFormDefault="qualified"> 
    <xs:element name="registroResponse">  
     <xs:complexType> 
      <xs:sequence> 
       <xs:element maxOccurs="unbounded" minOccurs="0" name="codigosError" nillable="true" type="tns:registroError"/> 
       <xs:element minOccurs="0" name="idTramite" type="xs:string"/> 
       <xs:element minOccurs="0" name="xml" type="xs:base64Binary"/> 
      </xs:sequence> 
     </xs:complexType> 
    </xs:element> 
    <xs:element name="registroError"> 
     <xs:complexType> 
      <xs:sequence> 
       <xs:element minOccurs="0" name="codigo" type="xs:string"/> 
       <xs:element minOccurs="0" name="descripcion" type="xs:string"/> 
       <xs:element minOccurs="0" name="detalles" type="xs:string"/> 
      </xs:sequence> 
     </xs:complexType> 
    </xs:element> 
</xs:schema> 

任何人都知道發生了什麼事？提前

Answer 1

<schema file=""/>提供空路徑，JAXB有沒有要處理。

Attribute Description 
------------------------------------------ 
schema  A schema file to be compiled. A file name (can be relative to the build script base directory), or an URL. This or nested <schema> elements are required. 
destdir  Generated code will be written under this directory. If you specify target="abc/def" and package="org.acme", then files are generated to abc/def/org/acme. 
catalog  Specify the catalog file to resolve external entity references. Support TR9401, XCatalog, and OASIS XML Catalog format. See the catalog-resolver sample for details.
