[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?

What's the line normally used to launch the app at runtime? That, together 
with CLASSPATH will tell you what class should be executed as main()

There is a file called startjalbum.sh which is supposed to be used to
start the program.  It contains:

#!/bin/sh
java -Xmx400M -jar JAlbum.jar

Does that tell you anything?

Yes, it does. There's a file called JAlbum.jar which contains the app, and 
it's location is visible to the script. There's no path so I'm assuming the 
file is in the current directory.

A .jar is just a special kind of zip file (much like OOo files are). What's 
inside it?

p.s. I don't know how familiar you are with Java's start-up process and how it 
finds things and how you specify things to find. It's somewhat unusual and 
many traps exist for the unwary :-)

I'm completely clueless with java.  Thanks a lot for your help thus far.

No, it has clearly already loaded at least one class (last line of that 
stack trace reveals this), and is looking for some others needed by that 
class -- but the classloader fails to find them. JAlbum probably also 
has a Main-Class header defined in the jar's manifest, so this is likely 
to be just another classpath-related issue.

But the ebuild you're pushing ... I think it would need some serious 
work for the installation part. I think it installs files in all wrong 
places, and thus Gentoo's Generation 2 java system cannot automatically 
add them to classpath.

There is some advice on the issue in section 3, the Filesystem layout 
over here:

http://www.gentoo.org/proj/en/java/java-devel.xml

After trudging through that you might understand why Gentoo Java team 
has constantly several dev positions advertised on "help wanted". Some 
of Java's ways don't mix that well with Gentoo's approaches, especially 
with compiling and packaging (installations).

If you are in a hurry of some sort, you might just try taking the jar, 
unpacking it into a subdir under your homedir, cd'ing in, and trying 
something like "CLASSPATH=.:${CLASSPATH} foo.sh". With a little luck it 
might work as such, without the pain of making a proper ebuild for it.

In its current state I'd say "no", it needs major fixes and polishing.
I'll see if I can do something for it later today, but I cannot
promise I can fix it properly.

I'm not sure what you mean.  That file doesn't exist in the installation.

Another option is to use the start script supplied in the bug:

http://bugs.gentoo.org/show_bug.cgi?id=128356
http://bugs.gentoo.org/attachment.cgi?id=97807

but I'm not sure how to get it to install somewhere useful.  Just
putting it in the files dir, I don't think anything happens with it.
Any pointers on that?

That'S what should be created with

I added an alternate ebuild to the bug. It doesn't need external
runner scripts. With it JAlbum-.8.5.1 seems to start-up nicely even on
amd64, asks for some kind of login (I canceled out from that screen),
and then allows one to ... well, design album covers, I guess. :)

That's how far I tried it. Now it starts up, but I still don't know if
all the dependencies got properly laid out. And reading into the
ebuild should reveal many pieces still needing work.

Thank you very much Arttu.  It works great!  JAlbum is a photo
management app BTW.  It's really slick.

So all the new dependencies were required to create /usr/bin/jalbum?

I'm sorry Arttu, I spoke too soon.  I only did a cursory check before.
 The program doesn't seem to work at all when installed via the new
ebuild.

The only way I can get the program to run properly is to install via
the old ebuild, 'chmod 755 /usr/lib/JAlbum/startjalbum.sh', 'cd
/usr/lib/JAlbum', and './startjalbum.sh'.  I'd like the ebuild to
leave the user with a command that can be put into a simple launcher
though.  Should I have the ebuild chmod, cp, and alter the contents of
the .sh script to provide the full path of JAlbum.jar so cd isn't
necessary?

I realized that I can issue 'java -Xmx400M -jar
/usr/lib/JAlbum/JAlbum.jar' to launch the program.  I've attached a
new ebuild to the bug that is pretty simple and includes some stuff
from your ebuild.
