Can tapestry run on Android
Hi,
I was just wondering before I look too closely if anyone knows if a
Tapestry webapp can run on Android?
I see there is an Android port of Jetty.
Thanks, Ryan

OT: Why would you want to host a web application on android ? Why not just
linux ?
Also tapestry IoC can be used independently from a servlet container. I've
done it on windows but not on android though.

Didn't mean to hijack the thread, just a note to say the github mirror is
ways behind the current repo, the github one is based on the old git://
git.apache.org/tapestry-5.git and it should be modified to reflect the
current settings.

I see that there is an ASMDEX project, this is probably the easiest option
to get plastic working on dalvik
http://asm.ow2.org/doc/tutorial-asmdex.html
You must be note that the tapestry build includes a repackaged copy of the
ASM libraries
https://github.com/apache/tapestry-5/tree/master/plastic/src/external/java/org/apache/tapestry5/internal/plastic/asm
I think that the only difference is the package name so that tapestry's
version of ASM does not clash with hibernate etc. Best to check with the
tapestry team if you plan to go down this route.
Good luck!
Re: Can tapestry run on Android

That's true. I didn't think of that.
I'm running tapestry 5.1 for this particular app (I'm wanting to port an
app over to android), I think it uses something else for byte code
manipulation, but it is still byte code and hence not dalvik compatible :(
And byte code manipulation is pretty core to Tapestry, so I guess there
isn't really much hope of getting it going, not unless there is an
Android version of ASM (or whatever it is using, javassist?, I can't
remember) ?
Or would it be possible to get Tapestry to pre-generate the byte code
rather than at runtime?
Thanks, Ryan

Tapestry uses ASM under the hood for it's runtime byte code manipulation
magic. I'm pretty sure that this would fail on dalvik.

True, but it lacks most of the linux core libraries (eg. glibc), so you
can't install Java SE Embedded on there, or most other things, without
porting it.

Custom built app for a lab that does environmental monitoring. So it
isn't widespread, hence why I don't want to spend lots of money :).
Usually with custom built software it is the software cost that gets out
of control, in this case it is the hardware cost (If we can easily port
it over)

Ideally android, because the manufacturers don't usually support
anything else for the majority of ARM tablets. But I might try running
linux first on an ARM tablet and see how it goes. Might be missing some
drivers I suspect. But I can live with that as long wifi and the screen
work and battery life remains decent.
Then tapestry modifications can be secondary :)
I guess last off would be to re-write the user interface to not use
tapestry, but it works really well at the moment and would cost a bit to
rewrite it all. Also then we've have to maintain 2 UIs, one mobile and
one for the main system.

Hmm, I forgot about the bytecode enhancement, but I was thinking about
running it in a JVM anyway. If you can root an Android installation, you

So I guess my next question would be answered: does it need to run or
Android specifically or in ARM devices? For Android, I'm not sure, but for
ARM devices, the answer is a huge yes. :)
If you need it for Android, I'm almost sure there's some way to precompile
the page and components transformations so you could use
JVM-bytecode-to-Dalvik bytecode converter, just that it wasn't done yet.

Yes, but the bytecode enhancement that tapestry does, it wouldn't be
able to be understood by the Dalvik JVM? As is my understanding. I just
don't want to spend a lot of time getting it set up, then have no
possibility of it working :)
> Question to the original question: why?

Just to satisfy curiosity :). We have a web app built with tapestry and
a mobile app that goes along with it. The mobile app runs offline then
syncs with the main app. It shares a lot of code, including the tapestry
interface. So it runs it's own tapestry server, and uses an embedded web
browser (xulrunner) to connect to it. It was a lot simpler in
development doing it this way than re-writing all the user interface for
offline support.
But this was before arm tablets were readily available. So we ran it on
Windows tablets. But these days a decent rugged windows tablet (doesn't
actually exist haha) is about $4000, whereas I can get a galaxy note and
a waterproof case for $500 which will do the job.
So we are looking at the cheapest way to port it over to android, but I
guess an alternative would be linux.

You're mixing apples and oranges here. First you talked about where
Tapestry can run, then, in the second sentence, talked about where
Tapestry pages can be viewed.
Answer to the original question: as long there's a servlet container
running in Android, you can run Tapestry on it just fine.
Question to the original question: why?

We were thinking the bytecode enhancement that tapestry does wouldn't
work because android runs on Dalvik. I guess I'll try it?

No. Tapestry only needs Java libraries, so, if you have a servlet
container running, you have a JVM and you can run Tapestry on it.

Thanks. I will try it, just doing some preliminary investigation before
investing some time. I haven't done any android development before, so I
only know the basic theory.

The bare bones Tapestry should run fine. It's very simple to test, why
don't you just try it? Depending on the target version of Android, you may
have some issues with libraries trying to use unsupported operations of the
VM but on recent versions it should all just work.

Sorry, just to clarify a bit I mean hosting it on Android. There is a
port of Jetty for Android, so will it run in that, but does Tapestry
require some libs that aren't on android?

Tapestry itself runs on a web container, like tomcat. The served pages will
operate in chrome in android and probably firefox as well, though I haven't
tested it there.
You can also use jQuery mobile for added capabilities, but a dedicated
project like tapestry-jQuery doesn't exist yet as far as I know.
