问题描述
我正在尝试使用 sql;query 从 XSLT 查询 oracle 数据库，我正在使用 sql9-sql.jar 和 saxon EE 9.6.0.7 版本，其中我已将 ojdc6.jar 也放在 eclipse 的构建路径中.我收到以下错误
I am trying to query oracle database from XSLT using sql;query, i am using sql9-sql.jar along with saxon EE 9.6.0.7 version where in i have placed ojdc6.jar also in buildpath of eclipse. I am getting below error
队列名称是错误 in xsl:value-of/@select on line 37 column 65 of pro.xsl: XTDE1450: Unknown extension instructions 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: 在 net.sf.saxon.expr.ErrorExpression.evaluateItem(ErrorExpression.java:127) 的未知扩展指令在 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) 在 net.sf.saxon.expr.Atomizer.evaluateItem(Atomizer.java:37) 在 net.sf.saxon.expr.AtomicSequenceConverter.evaluateItem(AtomicSequenceConverter.java:311) 在 net.sf.saxon.expr.AtomicSequenceConverter.evaluateItem(AtomicSequenceConverter.java:34) 在 net.sf.saxon.expr.instruct.ValueOf.evaluateItem(ValueOf.java:313) 在 net.sf.saxon.expr.instruct.ValueOf.evaluateItem(ValueOf.java:45) 在 net.sf.saxon.expr.instruct.SimpleNodeConstructor.iterate(SimpleNodeConstructor.java:281) 在 net.sf.saxon.expr.instruct.BlockIterator.next(BlockIterator.java:49) 在 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) 在 net.sf.saxon.trans.Mode.applyTemplates(Mode.java:456) 在 net.sf.saxon.trans.TextOnlyCopyRuleSet.process(TextOnlyCopyRuleSet.java:65) 在 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) 在 net.sf.saxon.jaxp.TransformerImpl.transform(TransformerImpl.java:183) 在 com.thbs.viniReq.TransformXsl.main(TransformXsl.java:553))
这是我的java代码:
Here is my java code:
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();
}
这是我的 XSLT:
Here is my XSLT:

如果我遗漏了什么，请告诉我.因为我从过去 3 天就陷入了困境.提前致谢.
Kindly let me know if i am missing on something. As i am stuck in it from past 3 days. Thanks in advance.
推荐答案
我无法立即看出这里出了什么问题，但我想到的第一种可能，应该作为可能的原因进行调查和消除，是未找到许可证文件.(这将导致 Saxon 基本上在 Saxon-HE 模式下运行.)因为您手头有 Configuration 对象，所以最简单的检查方法是
I can't immediately see what's wrong here, but the first possibility that comes to mind, which should be investigated and eliminated as a possible cause, is that the license file isn't being found. (This would cause Saxon to run essentially in Saxon-HE mode.) Since you've got the Configuration object to hand, the simplest way to check this is
config.isLicensedFeature(Configuration.LicenseFeature.ENTERPRISE_XSLT)
config.isLicensedFeature(Configuration.LicenseFeature.ENTERPRISE_XSLT)
如果确实是许可证问题，那么我们需要查看类路径.我注意到您在 Eclipse 中运行，并且在 Eclipse 中动态加载可能相当古怪.
If it does turn out to be a license issue then we need to look at the classpath. I note you are running in Eclipse, and dynamic loading in Eclipse can be fairly quirky.
