Compiling akka on OS X

[Stefan Plantikow]

Hi,

I ran into some trouble setting up akka on os x.

(1) I had to manually mvn install in util-java at one point, otw a
toplevel mvn install would fail due to missing artefacts

However, this issue seems to have gone with current git head.

(2) I dont know how bad this is but mvn complains about multiple scala
library version being in the buildpath (both 2.7.4 and 2.7.5 are
pulled by mvn)

[WARNING] Multiple versions of scala libraries detected!

(3) Building the kernel yields

/usr/local/src/akka/kernel/src/main/scala/reactor/
EventBasedThreadPoolDispatcher.scala:311: error: type mismatch;
found : java.util.Collection[_$1] where type _$1 <:
java.util.concurrent.Callable[T]
required: java.util.Collection[java.util.concurrent.Callable[?]]
def invokeAll[T](callables: Collection[_ <: Callable[T]]) =
executor.invokeAll(callables)

^
/usr/local/src/akka/kernel/src/main/scala/reactor/
EventBasedThreadPoolDispatcher.scala:312: error: type mismatch;
found : java.util.Collection[_$2] where type _$2 <:
java.util.concurrent.Callable[T]
required: java.util.Collection[java.util.concurrent.Callable[?]]
def invokeAll[T](callables: Collection[_ <: Callable[T]], l: Long,
timeUnit: TimeUnit) = executor.invokeAll(callables, l, timeUnit)

^
/usr/local/src/akka/kernel/src/main/scala/reactor/
EventBasedThreadPoolDispatcher.scala:313: error: type mismatch;
found : java.util.Collection[_$3] where type _$3 <:
java.util.concurrent.Callable[T]
required: java.util.Collection[java.util.concurrent.Callable[?]]
def invokeAny[T](callables: Collection[_ <: Callable[T]]) =
executor.invokeAny(callables)

^
/usr/local/src/akka/kernel/src/main/scala/reactor/
EventBasedThreadPoolDispatcher.scala:314: error: type mismatch;
found : java.util.Collection[_$4] where type _$4 <:
java.util.concurrent.Callable[T]
required: java.util.Collection[java.util.concurrent.Callable[?]]
def invokeAny[T](callables: Collection[_ <: Callable[T]], l: Long,
timeUnit: TimeUnit) = executor.invokeAny(callables, l, timeUnit)


This can be fixed be commenting these methods out and their
alternatives in (cf source).


(4) Now everything builds nicely, but there are lots of test failures:

I guess due tot this, no jars get installed into the m2 repo.

(5) Therefore I cant start the examples. Manually deploying and hoping
for the best:

mvn jar:jar
mvn install:install-file -DgroupId=se.scalablesolutions.akka -
DartifactId=akka-kernel -Dversion=0.5 -Dpackaging=jar -Dfile=akka-
kernel-0.5.jar

start-akka-server.sh dies since it tries to use 2G of mem on a 2G

I'd say -Xmx1G is more reasonable for most people's machines... ;-)

after manually copying akka-kernel-0.5.jar to libdir it starts but at
this point things are screwed way to badly so it just bails with a
wild:

(9) And now to my actual question, hoping that all of the above
problems eventually will dissolve :-)

Is it possible to use akka without the persistence/transaction layer?
I'm mainly interested in using the monitoring and network/
serialization bits.
Would be nice if there was an example on how to do that.

Thanks for your time and effort,

1. Are you running Java 6?
2. I think the tests fail because you haven't set AKKA_HOME

I see the same errors, and I have AKKA_HOME set and run Java 6.

Greetings,

Any clues?

You need to run Java 6.
Try with that. Let me know.

ok, switching to 1.6 helped a lot, sry wasnt clear to me from your
earlier remark.

now toplevel mvn install fails during building samples-lift and
compiling
samples-scala/java manually bails out with this:

ok, now running the sample server seems to go fine at first but then
dies even if adding the sample-java.jar to the classpath manually

If you haven't built your samples-scala module, you'll have to remove sample.scala.Boot from your akka.conf

Ok. I'll look at that. Thanks.

When running in kernel mode (e.g. the startup script). Then the jars
with boot classes and actors etc. need to be put in the ./deploy dir.
That is done automatically by maven if you run 'mvn install' from the root.

See the new samples-lift for an example of webapp mode.

Thanks Viktor. Right. The boot classe in the config (akka.conf) needs
to be in the JARs in the deploy dir.

[Stefan Plantikow]

I'm still not there...


Everything build now, is deployed in jars in deploy, but when I start
the sample server it still complains that

INF [20090805-16:04:27.526] kernel: REST service started successfully.

btw mvn deploy of samples still gives the weird error message about

[INFO] Failed to configure plugin parameters for:
org.apache.maven.plugins:maven-deploy-plugin:2.4

Greetings,


Stefan.

PS: $AKKA_HOME/deploy looks like this:

508 seeker:deploy $> ls -1
akka-samples-java-0.5.jar
akka-samples-scala-0.5.jar
logs
root
storage

[Jonas Bonér]

Sorry. I have no clue at the moment.

Anyone else have had problems like that?

You can debug yourself if you like. Look into the Kernel.scala class.
There is a method there that loads all the jars from deploy dir and
tries to load the boot classes in them.

Do a new pull first since I have done some stuff there that could
affect your problem.

Let me know if it persist. I am going away now for 3 days. Can look at
it when I get back (on the train now).

Sure you can.

For the persistence simply don't use any of the Persistent/
Transactional data structures.

The STM default semantics is SUPPORTS. Eg do not start a new but join
one if there is one. It has a slight overhead though. Therefore you
can turn it off completely either in the akka.conf or
programmatically. See the reference docs for details.

> Would be nice if there was an example on how to do that.

Yeah. I will try to write one soon.

Thanks for trying Akka out.
Do you have a real case for it or is it just for fun?
