As stated before, it was just a simplified example.

The enum is part of a 3rd party lib. And of course, there are several
workarounds available, but I want to understand what is happening here and
clearify if it's a bug.
And it's not just the c:out tag - it also happens with other Tags. For
demonstration I've created a custom Tag:
public class MyCustomTag implements Tag {
public void setValue(String value) {
System.out.println(value);
}
@Override
public void setPageContext(PageContext pc) {
}
@Override
public void setParent(Tag t) {
}
@Override
public Tag getParent() {
return null;
}
@Override
public int doStartTag() throws JspException {
return SKIP_BODY;
}
@Override
public int doEndTag() throws JspException {
return EVAL_PAGE;
}
@Override
public void release() {
}
}
My TLD:
<?xml version="1.0" encoding="UTF-8" ?>
<taglib xsi:schemaLocation="http://java.sun.com/xml/ns/javaee web-
jsptaglibrary_2_1.xsd" xmlns="http://java.sun.com/xml/ns/javaee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="2.1">
<tlibversion>1.0</tlibversion>
<uri>http://my-domain.org/customLib</uri>
<tag>
<name>customTag</name>
<tagclass>mypackage.MyCustomTag</tagclass>
<bodycontent>empty</bodycontent>
<attribute>
<name>value</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
</taglib>
And in my JSP file is use it:
<%...@taglib prefix="myLib" uri="http://my-domain.org/customLib"%>
<myLib:customTag value="${myEnum}"/>
<myLib:customTag value="foo.${myEnum}.bar"/>
I would expect, that this outputs:
VALID
foo.VALID.bar
The output in catalina.out is very interesting:
VALID
foo.VALID result, code 0.bar
Remember, VALID is the enum name() and "VALID result, code 0" is the enum
toString(). I think that is REALLY weird...
Bye
Oliver
