Matus Zamborsky commented on WFLY-2690:
---------------------------------------
Hello,
I have one (will upload it shortly). It really is a problem of weld. I went a little bit
deeper and even find the problem. The problem is in
[org.jboss.weld.annotated.slim.AnnotatedTypeIdentifier |
https://github.com/weld/core/blob/master/impl/src/main/java/org/jboss/wel...].
Deep down it is used as a key in caching Annotated types and as you can see from sources
of this class, it uses only className (and other attributes) to distinguish between
classes. But Wildfly uses different class loaders for every JSP (and included tags).
The problem manifests as casting exception from class A1 to class A2 (where A1 and A2 have
the same class name but are loaded with different classloaders).
I rewrote AnnotatedTypeIdentifier so it uses the class object instead of className and it
looks promising (no exceptions). But I am not a weld developer, and don't really know
if it wont have any other consequences.
JSP/JSPX tags doesn't work with Wildfly CR1
-------------------------------------------
Key: WFLY-2690
URL:
https://issues.jboss.org/browse/WFLY-2690
Project: WildFly
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Web (Undertow)
Affects Versions: 8.0.0.CR1
Environment: OpenJDK Runtime Environment (fedora-2.4.3.0.fc18-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
Reporter: Otávio Garcia
Assignee: Stuart Douglas
My app works fine on JBoss AS 7.1. When I migrate to Wildfly 8.0.0 CR1, my JSP tags
don't work as expected. My project is a EAR with WAR module.
When app starts, in the 1st access to page A, tag file is compiled and the page are
rendered fine. But when I access another page (B in example), I got this error:
org.apache.jasper.JasperException: java.lang.ClassCastException:
org.apache.jsp.tag.web.default_tagx cannot be cast to org.apache.jsp.tag.web.default_tagx
If I restart Wildfly and try to access page B, works fine. But when I access page A, I
got the same error.
My default.tagx is bellow:
<jsp:root
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:html="http://www.w3.org/1999/xhtml" version="2.2">
<jsp:output doctype-root-element="HTML"
doctype-system="about:legacy-compat" omit-xml-declaration="yes" />
some code
<jsp:doBody />
more code
</jsp:root>
And the pages are somethink like this:
<tags:default xmlns:tags="urn:jsptagdir:/WEB-INF/tags"
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:html="http://www.w3.org/1999/xhtml">
<jsp:output omit-xml-declaration="yes" />
my code here
</tags:default>
I was created a new empty project with two pages and one tagfile. The error don't
occurs. But when I add CDI capabilities, the error occurs. There are something in CDI that
confuses Jastow?
