[5] EL parsing eats extra character after '?'

Sat, 31 May 2003 03:54:18 -0700

Attached below is a message from tomcat-user. I don't know it this is a valid issue or not. If its not, it has great FAQ potential.

If it is a problem, could it be caused by the following the snippet below? It looks like any custom tag would be ignored if preceded by a $. This seems to be the behavior I saw when I put $ in front of the hello world tag in /jsp-examples/jsp2/tagfiles/hello.jsp.


In org.apache.jasper.compiler.Parser.parseXMLTemplateText()
lines 1502, 1506
                    if (ch != '{') {
                        ttext.write('$');
                        ttext.write(ch);
                        continue;
                    }


I really don't know much about Jasper, and was just snooping.

Subject: Tomcat 5.0.2 Bug

I think there is a bug in Tomcat 5.0.2 (at least under
Windows XP) dealing with placing a $ before (at least
some) tags.

Consider the following JSP:

<jsp:useBean id="login" class="LoginBean"
scope="session"/>
<jsp:setProperty name="login" property="username"
value="foo"/>

<html>
  <body>
    $<jsp:getProperty name="login"
property="username"/>
  </body>
</html>

In Tomcat 4.1.24, this generates the following HTML
(as expected)

<html>
  <body>
    $foo
  </body>
</html>

In Tomcat 5.0.2, it generates

<html>
  <body>
    $<jsp:getProperty name="login"
property="username"/>
  </body>
</html>

****The jsp taglib does not get processed in
5.0.2.****  Note that if I add a space after the $, it
works in 5.0.2

Changing to

$ <jsp:getProperty name="login" property="username"/>

gets the following HTML

<html>
  <body>
    $ foo
  </body>
</html>

Am I missing something?  I didn’t find the problem in
either the bugs database or the mailing list archives.
