Forum posting describing how to workaround this issue:

First add the schema info in the ACE TLDBuilder class, and then if that's not sufficient, look into modifying the generator code to output the TLD in a manner more conforming to the schema. Sometimes this just involves outputting the tags in a different sequence.

I think the description tag was in the wrong place (and the version number in the wrong format)

A few things here:

• version number in build.properties wasn't conforming to dewey-versionType format
• Required.java has an enum for whether attributes are required, values must be yes/no or true/false. OPTIONAL and REQUIRED are invalid.
• <documentation> elements must be earlier in both tag and attribute elements.
• Restored the xmlns, xmlns:xsi, and xsi:schemaLocation attributes on the document node as they were mistakenly removed.
• <display-name> element must occur earlier in the <taglib> root.

There is still an issue with the build. At the end of the component build the tlddoc target issues the following exception:

tlddoc:
[mkdir] Created dir: C:\icefaces2-demo\icefaces2\ace\component\build\doc\tld
[java] Loading and translating 1 Tag Library...
[java] com.sun.tlddoc.GeneratorException: Error: C:\icefaces2-demo\icefaces2\ace\component\build\exploded\META-INF\components.tld does not have xmlns="http://java.sun.com/xml/ns/j2ee"
[java] at com.sun.tlddoc.TLDDocGenerator.createTLDSummaryDoc(TLDDocGenerator.java:553)
[java] at com.sun.tlddoc.TLDDocGenerator.generate(TLDDocGenerator.java:439)
[java] at com.sun.tlddoc.TLDDoc.main(TLDDoc.java:217)

I can change the xmlns attribute to: http://java.sun.com/xml/ns/j2ee, which solves the above error, but JBoss complains about expecting javaee, it is defined as the xmlns in http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd which is a mismatch.

The above exception doesn't affect the generated output, however, and the currently checked in files creates a tld that allows applications to run in jboss 6.0.0-M5

I've checked in version 1.3 of the taglib generating tool. This solves the problem with the namespaces.

I had this fixed, but changes for 6207 re-introduced an issue with the tld. If we're going to want to put other information into the tld for IDE's, we're going to have to do it outside the method for generating a TLD that is conformant to the schema.

I've removed the changes for 6207 from the TLDBuilder. They were in the wrong place as part of a misunderstanding.
