在XSLT中调用Java函数

我有一个在xslt中使用java调用方法的案例研究

下面是我的XSLT：-

 <xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:test="java:com.package_name.com.Test">
<xsl:output method="xml" omit-xml-declaration="yes"/>
 <xsl:template match="/" >
    <xsl:for-each select="info/data">
    <xsl:variable name="VALUE" select="number"/>
    <int>
         <xsl:value-of select="test:calculate($VALUE)"/>
    </int>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

我收到如下错误消息：

Type:INTEGER:5
                                    Text:CHARACTER:Transformation failure when processing Stylesheet deployed:./Test.xsl

有人能告诉我如何在XSLT中调用java函数吗。 提前谢谢

问候,，

您能给我们看一下

calculate

方法的签名吗？它需要哪些参数，它们有哪些Java类型？这完全取决于您使用的XSLT处理器：您需要告诉我们。（啊，从堆栈跟踪的深度来看，它看起来像Xalan。我添加了一个标记。）calulate方法什么都不是，，，只是简单的if-else语句@MartinHonnen@rohit31dec91,我们需要查看

calculate

方法的参数数量和类型的定义，因此请编辑您的问题并显示这些信息。@MartinHonnen我添加了java的calulate函数。看看你能不能在某些方面纠正我。
