xalan2.6.2在jdk1.4中运行时问题，已经卡到这里三天了，求救，另开贴加分

最近做一个通过xslt解析动态XML的网站
环境:
weblogic8.0
采用了xalan-j-current-bin-2jars和jakarta-taglibs-20050329中的xtags
基本功能都实现了，可对于扩展（script）支持出错
script For extension function, could not find method
我尝试在tomcat下报错为：
org.apache.taglibs.xtags.util.JspNestedException: javax.xml.transform.TransformerConfigurationException: javax.xml.transform.TransformerException: java.lang.IllegalStateException: can't declare any more prefixes in this context
org.apache.taglibs.xtags.util.JspNestedException.fillInStackTrace(JspNestedException.java:68)
java.lang.Throwable.<init>(Throwable.java:195)
java.lang.Exception.<init>(Exception.java:41)
javax.servlet.jsp.JspException.<init>(JspException.java:47)
org.apache.taglibs.xtags.util.JspNestedException.<init>(JspNestedException.java:45)
org.apache.taglibs.xtags.xslt.StyleTag.handleException(StyleTag.java:357)
org.apache.taglibs.xtags.xslt.StyleTag.doEndTag(StyleTag.java:163)
org.apache.jsp.demo_jsp._jspService(demo_jsp.java:101)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)应是xalan对jdk1.4的兼容问题，请问高手怎么配置啊~！！
