Re: [ecf-dev] ECF Spring Support

[Angelo zerr <angelo.zerr@xxxxxxxxx>]

I ECF Team,

If you are interested with Spring DM and ECF,  you can find examples projects (+ Spring support to declare IContainer) into bug 302113

For the wiki I'm waiting for know if you like that and if you like that where I can write post into ECF wiki to explain Spring DM+ECF and Spring support to declare IContainer. 

Hoping that you like it.

Hi Scott,

I have try to manage host remoting services with my Spring support (I'm using my LocalContainerFactoryBean class) and it works:) The bundle need NONE Java code, only XML file Spring is used. Here this XML file Spring :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:osgi="http://www.springframework.org/schema/osgi"

      http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">


   <osgi:reference id="containerManager"
       interface="org.eclipse.ecf.core.IContainerManager" timeout="1000" />

   <bean class="org.springframework.remoting.ecf.LocalContainerFactoryBean">
       <property name="containerManager" ref="containerManager"></property>
       <property name="containerType" value="ecf.generic.server"></property>
   </bean>

   <bean id="helloService"
       class="org.eclipse.ecf.examples.remoteservices.hello.impl.Hello"></bean>

   <osgi:service ref="helloService"
       interface="org.eclipse.ecf.examples.remoteservices.hello.IHello">
       <osgi:service-properties>
           <entry key="osgi.remote.interfaces" value="*" />
       </osgi:service-properties>
   </osgi:service>


</beans>

I think you can use Spring DM without my LocalContainerFactoryBean class which create the ECF IContainer, but with this class you are full declarative. I have seen your work about DS and you must create IContainer into Java.

I have intention to create a bug with my work but before I have several questions :

1. Package name.

1.1 org.springframework.remoting.ecf.*

My class LocalContainerFactoryBean is into the bundle org.springframework.remoting.ecf into the package org.springframework.remoting.ecf. I have choosen this package name because it's base package name of Spring remoting (ex : org.springframework.remoting.httpinvoker).

My question is do you agree to have this package name or do you prefer having a package name like org.eclipse.ecf.springframework ?

If it's going to be in the ECF repository is must be under the namespace org.eclipse.ecf.  If you would rather contribute it to the Spring codebase it could be named org.springframework.* ...and that would be completely OK with me, but you would have to engage the Spring people about using the org.springframework.* namespace.  That's not a bad idea BTW...i.e. notifying the Spring framework people about this work...as they have just proposed the Virgo project:

http://www.eclipse.org/proposals/virgo/

And the work you are doing could very well be considered a useful addition to that project.  So perhaps I will notify the people at Spring that I know of about this work (with your permission).

So, I would suggest something like org.eclipse.ecf.spring or org.eclipse.ecf.springframework.  But one question...is this *API* code (i.e. meant to be reused?) or would it be part of the example code?  If it's example code (showing the use of ECF remote services with Spring), then it should probably go in a namespace like:

org.eclipse.ecf.examples.*  ...e.g. org.eclipse.ecf.examples.spring or org.eclipse.ecf.examples.springframework.

1.2 hello consumer/host  example with Spring DM.

I have named my projects org.eclipse.ecf.examples.remoteservices.hello.springdm.consumer and org.eclipse.ecf.examples.remoteservices.hello.springdm.host.
Is it ok with that? (I have followed the DS name org.eclipse.ecf.examples.remoteservices.hello.ds.consumer)

Yes, that's good/fine.  The names are unfortunately long, but I think consistency will be better to maintain here (since this code will become part of the examples).

2. Question about IContainer.

I would like manage into my LocalContainerFactoryBean the URL (containerId) of client/server side, but I'm newbie with ECF and I don't know how manage that? Could you help me for that? Thank a lot.

Sure...I can/will help with that.  I'm not sure exactly what you mean by manage, though.  Let's discuss directly when we chat as per below.

If you have time and you want we could tchat together to discuss about Spring Support for ECF.

If you have access to Skype, please contact me at sblewis (skype user id).  If not please send an email directly to slewis at composent.com and we'll arrange some way to talk/chat directly.

Thanks...for your contribution.

Scott
