Hi, I did a small
JSP tag. Sometime it works, sometime it doesn't. I don't know why. The problem is located in description file. Thanks
---------- web.xml -------
<web-app>
<taglib>
<taglib-uri>MakerTagXML</taglib-uri>
<!-- sometime works, sometime not work -->
<taglib-location>/MakerTag</taglib-location>
<!-- always work perfectly
<taglib-location>/WEB-INF/MyBodyTag.tld</taglib-location>
-->
</taglib>
</web-app>
-------------- TLD file ---
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name>bodytest</short-name>
<uri>/MakerTag</uri>
<tag>
<name>mark</name>
<tag-class>MyBodyTag.MakerTag</tag-class>
<body-content>JSP</body-content>
<description>body tag
test</description>
</tag>
</taglib>
------------ JSP file ------
<%@ taglib prefix="test" uri="MakerTagXML"%>
<html>
<body>
<test:mark> this is a test </test:mark>
</body>
</html>
-------- Tag class file ------
public class MakerTag implements BodyTag{
private PageContext pageContext;
private Tag parentTag;
//methods from Tag
public void setPageContext(PageContext pageContext){this.pageContext = pageContext;
}
public void setParent(Tag parentTag){
this.parentTag = parentTag;
}
public Tag getParent(){
return this.parentTag;
}
public int doStartTag()throws JspException{
return BodyTag.EVAL_BODY_BUFFERED;
}
public int doEndTag() throws JspException{
return Tag.EVAL_PAGE;
}
public void release() {
}
// methods from IterationTag
public int doAfterBody()throws JspException{
try{
JspWriter out = bodyContent.getEnclosingWriter();
String text = bodyContent.getString();
out.print(text+" ffff ");
}catch(Exception e){
}
return 1;
}
//methods from BodyTag
private BodyContent bodyContent;
// save the body content in order to access the body content
public void setBodyContent(BodyContent bodyContent){
this.bodyContent = bodyContent;
}
// do some initialization steps on body content
public void doInitBody() throws JspException{
}
}
