撒克逊转换导致未知的扩展指令

Question

我想从XSLT使用sql查询oracle数据库;查询，我正在使用sql9-sql.jar与saxon EE 9.6.0.7版本在哪里我已经放置ojdc6.jar也在Eclipse的构建路径。我收到以下错误

queue name is Error in xsl:value-of/@select on line 37 column 65 of pro.xsl: XTDE1450: Unknown extension instruction in built-in template rule ; SystemID: file:/C:/home/oracle/workspace/XSLTsaxonEE/src/com/thbs/viniReq/pro.xsl; Line#: 37 net.sf.saxon.trans.XPathException: Unknown extension instruction at net.sf.saxon.expr.ErrorExpression.evaluateItem(ErrorExpression.java:127) at net.sf.saxon.expr.Expression.process(Expression.java:880) at net.sf.saxon.expr.instruct.DocumentInstr.evaluateItem(DocumentInstr.java:325) at net.sf.saxon.expr.instruct.DocumentInstr.evaluateItem(DocumentInstr.java:50) at net.sf.saxon.expr.Atomizer.evaluateItem(Atomizer.java:317) at net.sf.saxon.expr.Atomizer.evaluateItem(Atomizer.java:37) at net.sf.saxon.expr.AtomicSequenceConverter.evaluateItem(AtomicSequenceConverter.java:311) at net.sf.saxon.expr.AtomicSequenceConverter.evaluateItem(AtomicSequenceConverter.java:34) at net.sf.saxon.expr.instruct.ValueOf.evaluateItem(ValueOf.java:313) at net.sf.saxon.expr.instruct.ValueOf.evaluateItem(ValueOf.java:45) at net.sf.saxon.expr.instruct.SimpleNodeConstructor.iterate(SimpleNodeConstructor.java:281) at net.sf.saxon.expr.instruct.BlockIterator.next(BlockIterator.java:49) at net.sf.saxon.expr.instruct.Message.processLeavingTail(Message.java:214) at net.sf.saxon.expr.instruct.Block.processLeavingTail(Block.java:657) at net.sf.saxon.expr.instruct.TemplateRule.applyLeavingTail(TemplateRule.java:393) at net.sf.saxon.trans.Mode.applyTemplates(Mode.java:456) at net.sf.saxon.trans.TextOnlyCopyRuleSet.process(TextOnlyCopyRuleSet.java:65) at net.sf.saxon.trans.Mode.applyTemplates(Mode.java:433) at net.sf.saxon.Controller.transformDocument(Controller.java:2291) at net.sf.saxon.Controller.transform(Controller.java:1889) at net.sf.saxon.s9api.XsltTransformer.transform(XsltTransformer.java:553) at net.sf.saxon.jaxp.TransformerImpl.transform(TransformerImpl.java:183) at com.thbs.viniReq.TransformXsl.main(TransformXsl.java:90)

这里是我的Java代码：

public static void main(String[] args) throws XPathException { 

    System.setProperty("javax.xml.transform.TransformerFactory","net.sf.saxon.TransformerFactoryImpl"); 

    EnterpriseConfiguration config=new EnterpriseConfiguration(); 
    config.setExtensionElementNamespace("http://ns.saxonica.com/sql", "net.sf.saxon.option.sql.SQLElementFactory"); 

    EnterpriseTransformerFactory factory = new EnterpriseTransformerFactory(); 
    factory.setConfiguration(config); 
    try { 
     Transformer transformer = factory.newTransformer(new StreamSource(new File(xslt))); 

     transformer.transform(new StreamSource(new File(xml)), 
           new StreamResult(new File(resultDir))); 

     transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    }

这里是我的XSLT：

<xsl:variable name="queue-id">

<OrderNo>100001</OrderNo> 
<ReqUser>ff</ReqUser> 
</RequestHeader> 
</xsl:template> 

</xsl:stylesheet> 

请让我知道，如果我失去了某些东西。因为我在过去3天里陷入了困境。提前致谢。

我不能立即看到这里有什么问题，但是想到的第一个可能性是应该调查并消除这个可能的原因，那就是没有找到许可证文件。 （这将导致撒克逊人在撒克逊-HE模式本质上运行。）既然你已经得到了配置对象的手，以检查这个最简单的方法是

config.isLicensedFeature（Configuration.LicenseFeature.ENTERPRISE_XSLT）

如果它确实是一个许可证问题，那么我们需要看看类路径。我注意到你在Eclipse中运行，并且在Eclipse中进行动态加载可能会很古怪。
