[gentoo-user] ebuild help: java main class?

[Grant]

I'm trying to fix up the JAlbum ebuild:

http://bugs.gentoo.org/show_bug.cgi?id=128356

and get it to use java-pkg-2.  Here's what I have so far:

inherit java-pkg-2 eutils

S="${WORKDIR}/Jalbum"
DESCRIPTION="Web photo album generator"
HOMEPAGE="http://jalbum.net/";
SRC_URI="http://jalbum.net/download/Jalbum${PV}.zip";

LICENSE="as-is"
SLOT="0"
KEYWORDS="x86"
IUSE=""

DEPEND=">=virtual/jre-1.5"
RDEPEND="${DEPEND}"

src_install() {
    java-pkg_dojar JAlbum.jar
    java-pkg_dolauncher jalbum \
        --jar JAlbum.jar \
        --java_args -Xmx400M

    local dest=/usr/lib/${PN}
    dodir ${dest}
    cp -R ${S}/* ${D}/${dest} || die "Install failed"

    doicon ${FILESDIR}/Jalbum-icon.png
    make_desktop_entry ${PN}
}

It executes just fine, but I get:

$ jalbum
Error: se.datadosen.jalbum.JAlbum
java.lang.ClassNotFoundException: se.datadosen.jalbum.JAlbum
        at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
        at se.datadosen.jalbum.Main.main(Main.java:23)

I was told I need to define the main class with --main.  Does anyone
know how to determine what the main class should be?
