If you need to run JSTL 1.0 and want to use JSP expressions as attribute
values, you need to use the "RT-based" versions. For JSTL, there are
basically two distinct versions of each taglib:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%@ taglib prefix="c_rt" uri="http://java.sun.com/jstl/core_rt"; %>
If you look at the TLD files for JSTL 1.0, you'll see:
c.tld:
------
<tag>
<name>set</name>
...
<attribute>
<name>value</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
...
</tag>
c-rt.tld:
---------
<tag>
<name>set</name>
...
<attribute>
<name>value</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
...
</tag>
JSTL 1.0 has to handle EL evaluation on its own (it's integrated into JSP
2.0 so JSTL 1.1 doesn't need to do the evaluation), so you're forced to
make a choice between different taglibs that use EL expressions or JSP
expressions.

Hi everyone,
I was using JSTL 1.1 in my application, and then unfortunately, I had to
downgrade to 1.0. Now, my IDE is complaining about this line in my JSP
<c:set var="config" value="<%= Config.getInstance() %>"/>
It says "Attribute value does not accept runtime expressions.
This used to work perfectly when I was using 1.1. I tried to look at the
changes between 1.1 and 1.0 but I can not see anything related to this
issue. Is this really a difference between 1.0 and 1.1 or am I doing
something wrong?
Thanks in advance for your help.
