Subject Re: Vexing problem, XSP and Tag Library in [C2]
Date Sun, 18 Feb 2001 17:44:20 GMT
---Sorry my last mail has some format error.So I
resend a revised version of that mail again---

Dear Sirs: 

 I think you are both Cocoon-experts and 
 Cocoon-promoters. 
 Here I really need help from you. I tried dozens of
 time to use Tag Library feature with XSP under 
 [C2].
 It just fails.
 All I tested is just the simplest Time-of-Day Tag
Library example  under cocoon-xsp page:
 http://xml.apache.org/cocoon/xsp.html
 but I never work it out ! That means it doesn't
 work.
 I really hope anyone in this maillinglist can help
 me
 out of this essential
 function of XSP under Cocoon.
 Following are some configuration of my [C2] 
 enviorment. 
 In cocoon.xconf  I have added following : 
 ------cut here-------------- 
 <builtin-logicsheet> 
 <parameter name="prefix" value="tod"/> 
 <parameter name="uri" > 
 value="http://localhost:9095/cocoon/xsp/tod" 
 <parameter name="href" >
  value="context://docs/samples/xsp/eins.xsl"
 </builtin-logicsheet> 
 ------ cut here ----------- 
 In sitemap.xmap following are added: 
 ------cut here-------------- 
 <map:match pattern="xsp/tod"> 
 <map:generate type="serverpages" > 
 src="docs/samples/xsp/tod.xsp"
 <map:transform src="docs/samples/xsp/eins.xsl"
 <map:serialize/>
 </map:match> 
 -------------------------------------- 
 
  my tod.xsp which in

~/jakarta-tomcat-4.0-b1/webapps/cocoon/docs/samples/xsp
  is following: 
  ----------------------- 
 <?xml version="1.0" encoding="ISO-8859-1"?> 
 <xsp:page > 
 language="java" 
 xmlns:xsp="http://apache.org/xsp" 
 xmlns:xsp-request="http://apache.org/xsp/request" 
 xmlns:xsp-response="http://apache.org/xsp/response"
 
 xmlns:tod="http://localhost:9095/cocoon/xsp/tod" 
>
 <page> 
 <title>TOD Page</title> 
 <content> 
  <p> 
  To the best of my knowledge, it's now 
 <!-- Substitute time of day here --> 
  <tod:time-of-day format="hh:mm:ss"/> 
  </p> 
  </content>
 </page>
 </xsp:page>
 ------------------------------------------------ 
 The eins.xsl which in the same path as tod.xsp
 efined
 the time-of-day  <tod> tag lib is following: 
  ------------------------------------- 
  <?xml version="1.0"?>
 <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
 xmlns:tod="http://localhost:9095/cocoon/xsp/tod" 
 xmlns:xsp-request="http://apache.org/xsp/request"
 xmlns:xsp="http://apache.org/xsp"
 <xsl:template match="xsp:page">
 <xsp:page> 
 <xsl:copy> 
 <xsl:apply-templates select="@*"/>
 </xsl:copy>
 <xsp:structure>
 <xsp:include>java.util.Date</xsp:include> 
 <xsp:include>java.text.SimpleDateFormat</xsp:include>
 </xsp:structure> 
 <xsp:logic>
  /* "TOD" Class Level Logic */ 
 private static String formatDate(Date > date, String
 pattern) 
 { 
    if (pattern == null || pattern.length() > == 0) 
 	{ 
              pattern = "yyyy/MM/dd hh:mm:ss aa"; 
 	} 
 	return (new >
 SimpleDateFormat(pattern)).format(date); 
 } 
 </xsp:logic> 
 <xsl:apply-templates/> 
 </xsp:page> 
 </xsl:template>
 <xsl:template match="tod:time-of-day">
 <xsl:expr>
  formatDate(new Date(), "<xsl:value-of >
 select="@format"/>") 
  </xsl:expr>
 </xsl:template>
 <xsl:template match="@*|node()" priority="-1">
 <xsl:copy><xsl:apply-templates
 select="@*|node()"/></xsl:copy> 
 </xsl:template> 
 </xsl:stylesheet>
 --------------------------------------------------- 
  actually the eins.xsl and tod.xsp are almost the
 same
  as those on the cocoon-xsp page. My question is how
 can I make this tag lib example WORK! Can anyone
 check
 where I 'm wrong ?  All I need is a working
 self-defined taglib example. 
 
 thank you for your attention. 
 
 sincerely yours 
 --Zhi
 
 p.s: other examples in cocoon works but this one.
