Answer 1

The issue may be with your web.xml file. I had a similar issue with a portlet that worked fine under 6.1GA1 but not 6.1GA2. When Liferay deploys portlets (and hooks, etc.), it rewrites the file and others to add filters, libraries, etc. So the error is probably not with the file as you originally created it, but with what Liferay generated.

In my case, Liferay changed the first part of web.xml from

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

to something like

<?xml version=<filters>[other stuff]</filters>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

So it was a modified first line that caused the problem. I had some XML commented out using <!-- --> and removing those sections fixed the problem. But it's a bug IMHO.

Answer 2

Pay attention to tag "display-name" in your web.xml. Sometimes (and this is my case) Eclipse plugin creates a web.xml using "j2ee:display-name" tag. Deployer tries to append filter block configuration after "/display-name" tag position. When "j2ee:display-name" is present deployer appends filter block configuration to a bad position in file such as "version" attribute. Replacing "j2ee:display-name" tag with "display-name" tag resolves the problem.
