HTTP Status 500 -

note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 3.0.1 logs.

GlassFish Server Open Source Edition 3.0.1

The reason this happened is, that I referenced an entity “uuml;” in a xml document where it is not defined.
XML basically just supports a few build-in entities, like “amp;” “quot;”, “apos;”, “lt;” and “gt;”.

To let the SAX-Parser know which additional entities I wanted to use, I simply added the XHTML 1.1 DOCTYPE to the head of the document.
My Component now looks like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:composite="http://java.sun.com/jsf/composite">
<body>
<composite:interface>
....
</composite:interface>
 
<composite:implementation>
.... text &Uuml;bermorgen ist auch noch ein Tag ... text
</composite:implementation>
</body>
</html>

Hope this helps some of you out there.

In our example, we want to match a URL like this one

1

http://www.studyguru.eu/at/tuwien/184.153--Entwurfsmethoden-fuer-verteilte-Systeme

Previously I tried to match it with a PrettyFaces Pattern/Regex like this:

       <pattern value="/([a-z]{2})/([a-z0-9\-_]*)/([a-z0-9\-_\.]*)\-\-.*"/>

But thankfully, PrettyFaces >2.0.4 supports directly populating the RequestParams!

Configure your pretty-config like this:

1
2
3
4
5
6
7
8
9
10
11

<pretty-config xmlns="http://ocpsoft.com/prettyfaces/2.0.4"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://ocpsoft.com/prettyfaces/2.0.4
                http://ocpsoft.com/xml/ns/prettyfaces/ocpsoft-pretty-faces-2.0.4.xsd">
....
 
    <url-mapping id="coursePage">
        <pattern value="/#{countryCode}/#{uniShortName}/#{courseId}--.*"/>
        <view-id>/path/to/coursePage.xhtml</view-id>
    </url-mapping>
....

and use JSF2′s viewParams like this:

1
2
3
4
5
6

</f:metadata>
<h1>coursePage</h1>
 
countryCode #{ coursePageBean.countryCode} <br/>
courseId #{coursePageBean.courseId}<br/>

Voila! You now can match complex urls with PrettyFaces and apply all your custom validators
to your Pretty URL :)

CHANGES:

  • Replaced roles.isEmpty() with roles.equals(“”) to allow usage with Java 5
  • Adopted taglib for usage with Spring 3/Spring Security 3 final
  • removed faces-config.xml in taglibs for jsf 1.2 as it prevented deploying in some scenarios

Fetch it from the Project Homepage

I created a taglib based on the code of BalusC.
You can find the Taglib on Github

The source code is based on these two posts:

  1. Uploading files in Servlet 3.0
  2. Uploading files with JSF 2.0 and Servlet 3.0

Simply check out the code with git

1

git clone http://github.com/domdorn/fileUploadServlet3JSF2.git

then install the taglib with

1

mvn clean compile install

and import it into your maven project like this

net.balusc
fileUploadServlet3JSF2
1.0-SNAPSHOT

You can then use the taglib in your Facelets files like this:

Upload.xhtml

Nice one Lincoln!

Taken from https://javaserverfaces.dev.java.net/maven2, the required parts are:

If you use Glassfish v3 or higher:

1
2
3
4
5
6

<dependency>
		<groupId>javax.faces</groupId>
		<artifactId>jsf-api</artifactId>
		<version>2.0</version>
		<scope>provided</scope>
</dependency>

If you use Tomcat or Jetty (or any other non JEE6 compliant Servlet Container):

1
2
3
4
5
6
7
8
9
10

<dependency>
		<groupId>com.sun.faces</groupId>
		<artifactId>jsf-api</artifactId>
		<version>2.0.0</version>
</dependency>
<dependency>
		<groupId>com.sun.faces</groupId>
		<artifactId>jsf-impl</artifactId>
		<version>2.0.0</version>
</dependency>

 

However, If you put the JBoss repository either in your pom.xml or your ~/.m2/settings.xml

1
2
3
4
5

		<repository>
				<id>jboss</id>
				<name>Jboss Maven Repository</name>
				<url>http://repository.jboss.com/maven2/</url>
		</repository>

you can then use the following dependencies (which I think are more appropriate):

1
2
3
4
5
6
7
8
9
10
11

		<dependency>
				<groupId>javax.faces</groupId>
				<artifactId>jsf-api</artifactId>
				<version>2.0.0-FCS</version>
		</dependency>
 
		<dependency>
				<groupId>javax.faces</groupId>
				<artifactId>jsf-impl</artifactId>
				<version>2.0.0-FCS</version>
		</dependency>

Also Sun provides some simple JSF-2 archetypes

Although I would have chosen a different approach
(mainly extending the already existent h:message tag), Martins way works quite nice.
Thanks Martin!
