JSAGA

After upgrading to izPack5, the installer JAR is 50MB big.
To build a web installer, add the config param kind in the izpack-maven-plugin section in jsaga-installer.pom.xml:

            <plugin>
                <groupId>org.codehaus.izpack</groupId>
                <artifactId>izpack-maven-plugin</artifactId>
                <version>5.0.0-rc1</version>
                <configuration>
                    ...
                    <kind>web</kind>
                </configuration>
                ...

and param webdir in assembly/izpack.xsl:

            <info>
                <appname>JSAGA</appname>
                ...
                <webdir>http://maven.in2p3.fr/fr/in2p3/jsaga</webdir>
            </info>

see http://izpack.org/documentation/advanced-features.html#web-installers

This gives the following error:
