[Resin-interest] SAXParseException when using (jakarta's) JSTL in JSP

[Olaf Krische]

Hello,

currently i am trying to make my application of mine Resin 3.1 ready, while
it can still run on Resin 2.1. For this i use the jakarta standard tag
library (1.0.6), not for the tag implementations, but for its
EvaluationManager to be able to use EL in my tags.

Ok, this is what i do:

1. Download Resin 2.1 snapshot
2. Starting with "java -jar lib/resin.jar start"
3. http://localhost:8080/resin-doc/index.jsp

Works perfectly.

4. Now i add to resin-doc a new file "indexXML.jsp".
5. I add the standard.jar (1.0.6) to resin-doc/WEB-INF/lib/
6. Receiving now a SAXParseException, when calling
http://localhost:8080/resin-doc/indexXML.jsp

I dont know, what exactly is broken here. Any idea?

This is the complete exception message (jsp source is below)

500 Servlet Exception

/indexXML.jsp:1: org.xml.sax.SAXParseException: The prefix "c" for element
"c:set" is not bound.

1: <?xml version="1.0" encoding="UTF-8"?>
2: <jsp:root xmlns="http://www.w3.org/1999/xhtml"
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:c="http://java.sun.com/jstl/core" version="2.1">
3:

This is the indexXML.jsp:

<?xml version="1.0" encoding="UTF-8"?>
<jsp:root xmlns="http://www.w3.org/1999/xhtml"
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:c="http://java.sun.com/jstl/core" version="2.1">
<c:set var="locale">de_DE</c:set>
<c:out value="${locale}"/>
</jsp:root>

The jar can be found here ( i tried with 1.1.2, did not work as well)

I think in resin 3.1.x you should use http://java.sun.com/jsp/jstl/core
for the "c" JSTL tags. (note the extra "/jsp/")

Hello Erik,

thank you for your answer. And yes, you were right about the missing 'jsp' .
My heart started to bump. I have changed the example accordingly. Sadly, the
error will not disappear:

/indexXML.jsp:1: org.xml.sax.SAXParseException: The prefix "c" for element
"c:set" is not bound.

1: <?xml version="1.0" encoding="UTF-8"?>

It seems to work better if you use Rein's XML parser, i.e. add this to
your resin.conf:

<system-property
javax.xml.parsers.DocumentBuilderFactory="com.caucho.xml.parsers.XmlDocumentBuilderFactory"
/>
<system-property
javax.xml.parsers.SAXParserFactory="com.caucho.xml.parsers.XmlSAXParserFactory"
/>

There is a bug that looks very similar to this:
http://bugs.caucho.com/view.php?id=1647 that was marked as fixed in
version 3.1.1 -- maybe it's not completely fixed after all?

Hello Erik,

your idea to change the system properties did relax the error.

Thank you!

(I am unable to re-open the Bug or to submit a new bug, i dont get any email
from Mantis. Grmbl.)
