John,
So I tried your cool eval approach but the JSP page seems to no be able to
find the string once I have placed it in the page context using the eval
tag.
Here's my implementation of the eval tag...
public class EvalBody extends BodyTagSupport {
private String id;
/* 1) At the end of the tag this function gets called. */
public int doEndTag() throws JspTagException
{
try
{ /* 2) Get the text within the tag. */
BodyContent l_tagbody = getBodyContent();
String ls_output = "";
/* 3) If text was in the tag body then process it. */
if(l_tagbody != null)
{
String ls_html_text = l_tagbody.getString();
pageContext.setAttribute(id, ls_html_text);
//this is to verify that I am setting the property...
ls_output="body text:"+ls_html_text+" id:"+id;
}
/* 4) Write the result back to output stream */
pageContext.getOut().write(ls_output.trim());
}
catch (IOException e)
{
throw new JspTagException("Tag Error:" + e.toString());
}
/* Have the JSP Container continue the JSP page as normal. */
return EVAL_PAGE;
}
public void setId(String as_id)
{
id=as_id;
}
}
here's my JSP page code...
<!-- you need to handel the null case-->
<logic:iterate id="contextBean" name="ContextMgr"
property="contexts">
<tr>
<td><strong><bean:write name="contextBean"
property="name"/></strong></td>
<td><strong><bean:write name="contextBean"
property="description"/></strong></td>
<td>
<utility:EvalBody id='contextName'><bean:write
name="contextBean" property="name"/></utility:EvalBody>
<%String fullUrl="viewcontext.do?name="+contextName;%>
<strong><html:link href="<%=fullUrl%>">goto
context</html:link></strong>
</td>
</tr>
</logic:iterate>
and it fails to find the attribute on the page, here's the error...
org.apache.jasper.JasperException: Unable to compile class for
JSPC:\tc3.2.3\work\localhost_8080%2Fcontextuon\_0002fcontextmgr_0002ejsp
contextmgr_jsp_58.java:525: Undefined variable: contextName String
fullUrl="viewcontext.do?name="+contextName;
ok so it can't find the attribute even though I put it in the
pageContext...
wassup?
