[merlin] singleton not really a singleton ??
Hi,
since I made a new build this week I have problems with components which
are marked as singletons in the xtype-file
but get instantiated serveral times.
my setup is the following:
<block>
<info>
<name>proxy-server</name>
</info>
<implementation>
<engine>
<classpath>
<fileset dir="../common/lib/common/jentro">
<include name="com.jentro.http.jar"/>
</fileset>
</classpath>
</engine>
<categories name="proxy" priority="INFO" target="log"/>
<component name="http-server"
class="com.jentro.http.components.impl.HttpServiceImpl">
<categories priority="INFO" />
<configuration>
<port>4848</port>
</configuration>
</component>
. . . .
. . . .
<container name="delegator">
<engine>
<classpath>
<fileset dir="../navigation/lib/jentro">
<include name="guidance.jar"/>
</fileset>
<fileset dir="dist">
<include name="proxy.server.jar"/>
</fileset>
</classpath>
</engine>
<categories name="delegator" priority="INFO" target="log"/>
<component name="find-proxy-ip"
class="com.jentro.manager.proxy.client.server.FindProxyIPComposer"
activation="startup"/>
</container>
. . . .
</block>
this configuration starts fine and works correct. but if I an add attribute
activation="startup"
to the "http-server" component than at time of instanciating the
"find-proxy-ip" component I get an "address already in use"-exception,
because a second instance of the "http-server" is created :-(
the old build I use the last 2-3 weeks worked fine. so the question is
moreless: is this a bug or a feature ? for me the activation attribute
shouldn't have any effect on the singleton attribute. the effect I have
when I deploy more than one of these Composer (all different types).
I have another place where I end up with to many different instances of
singletons, but before digging into that I wanted to find out, if I
understand the concept of singleton within the container hierachy of a
block correctly.
with best wishes Kristian

Plugin looks ok.
So what exactly is the problem you are seeing?

Yes - assuming you using the work "block" in the Phoenix context - i.e.
a component with an xinfo describing services and dependencies.

If I understand correctly - you have a component that is receiving a
service manager and you want to pass this service manager on to other
objects. I would probably wrap the supplied service manager in another
service manager before exposing it.

This is workable.

You can always create a new service manager which contains additional
services.
DefaultServiceManager manager = new DefaultServiceManager();
manager.put( "some-key", myService );

Is there a problem declaring the dependencies that
the axis component has? I'm not really following
completely the dependencies/service graph in this
example.
In principal you should be able to state the set of
services needed by any component, and the set of services
published by each component. From that you should be
able to draw a graph that connects provider components
with consumer components.
Hope that helps.
Steve.

merlin manage services lifecycle good, lifestyle good,
services life quality need enhanced. they(services)
make friends not easy. jndi is a goods way making
firends of services. u can limit a service only make
friends with permitted services.

Re: [merlin]my jndi extension suggestion
Posted by liu jie <cn...@yahoo.com.cn>.
when one block want to use other block
service,currently
it using servicemanager passed by serviceable
interface.
when my block dirve other modules, these moudles want
to
use other block's service, my block must pass it's
servicemanager
to these driven modules.
i write a block for jetty, jetty drive a servlet, the
servlet
want to use other block's service, i must pass jetty
block's
servicemanager to servlet in servletcontext, then the
servlet
get jetty block's servicemanager from servletcontext
and access
other block's services.
if my block logic complex , i must allways pass the
block's
servicemanagr from here the here.
i write a block for apache axis, axis is a soap
engine, it
can translate a soap message to a rpc invoking to a
webservice,
the soap engine only translate a soap message to a
webservice
rpc invoking. my webservice can not get the blocks
servicemanager,
so my webservice lonely and can not get other blocks
help(services).

The approach I've been working on is to embed the kernel inside a JNDI
implementation. This will enable full naming and directory
functionality while maintaining all of the publication/isolation
features within the merlin system.

They are orthoginal.
The serviceable interface provides support for a container to "push"
services to a component. JNDI provides support for an implememntation
to "pull" services in based on a standard naming and directory structure.

[merlin]my jndi extension suggestion
Posted by liu jie <cn...@yahoo.com.cn>.
i want to use merlin as services server(services
container),especially my module will be blocks. my
blocks don't want to access(dependency) other services
using servicemanager but jndi way.
i saw Peter Donald's excalibur-naming-1.0, i suggest
plug the jndi MemoryContext in merlin kernal.
if my block can access other services using jndi, what
is the function of servicable interface.

Re: [merlin] merlin intall faiure using maven ---help
Posted by Stephen McConnell <mc...@apache.org>.
Unfortunately the maven.log file is not terribly useful (it is typically
full of internal maven stuff).
Instead - could you post the information that maven is logging to the
console. This would give an indication of where the build is failing.
Secondly, have you applied the patch to Maven 9?

This problem is now fixed and updates have just been applied to CVS.
The problem was a non-synchronized new instance call from the singleton
lifestyle helper. If another request within a different thread for the
singleton instance was invoked before an inital request had completed,
the handler would invoke newInstance() again. The changes applied have
been to synchronize a code block dealing with the single instance
establishment.
Cheers, Steve.

Retration!
I've managed to establish a test case where I can get two different
instances for a singleton if I use the statup activation policy. Now I
can start digging.

Kristian:

particular singleton is not supplying the same instance identity
(indepedently of any activation policy). I.e. everything appears to be
functioning correctly.
Casn you post the xinfo file of the component that is not behaving like
a singleton?
Steve.
p.s. to be real confident about your environment:
1. do a CVS update
2. delete the jar files in the merlin installation directories:
/lib/shared
/lib/system
3. invoke the command:
$ maven merlin-libs
4. if the problem persists at least you keno you have a clean
installation.

It's a bug.
I was doing messing with the activation policy stuff a couple of weeks
ago - looks like I've done something silly.

What you expecting to happen should be happening. I'm going to put
together a testcase asap and see what is happening.
