Connection hangs after all work is done

webworks2000 — Tue, 01 May 2007 13:18:10 GMT

I've noticed on all of the examples in the SDK, the programs are ended by a [size=117]System.exit(0)[/size] call. I've tried to write some code without the exit call and it simply hangs at the end as if it's waiting for more to do. I realize this can be by design to reduce connection times, etc….

After looking into this more, it seems the following line is the one that causes the hang - even if it is the only line that deals with Alfresco


// either
ctx = ApplicationContextHelper.getApplicationContext();
// Or
ctx = new ClassPathXmlApplicationContext("alfresco/application-context.xml");

Hi,

    public static void main(String … args)
    {
        ClassPathXmlApplicationContext ctx = (ClassPathXmlApplicationContext) getApplicationContext();
        synchronized (ctx)
        {
            try { ctx.wait(10000L); } catch (Throwable e) {}
        }
        ctx.close();
    }‍‍‍‍‍‍‍‍‍

Alfresco doesn't control the lifecycle but responds to lifecycle callbacks provided by Spring. If the code above doesn't work (and I've just checked that it does) then a component has been added that isn't listening to the lifecycle callbacks.

Regards

Another thing is that you are starting the entire Alfresco server-level application context and then shutting it down. You should consider JCR-RMI and connect to an instance of the server that remains alive.

I am quite confused what would be your recommended way of embedding Alfresco inside own application (Tomcat + Liferay at development, JBoss + Liferay at production) using JCR.

After trying JNDI-JCR from Jira I have come to conclusion that it doesn't currently work with JBoss and after reading about RMI-JCR it seems that it's not yet fit to production. Now, as I have understood, there's left only embedding using JCR.Repository object which is got thru Sping from alfresco/application-context.xml.

Using Alfresco SDK means in our environment that we need to build maven2 script for SDK:s server and hope that classes of Liferay and Alfresco somehow manage together (differents spring versions, 1.x & 2.x, etc.). For that I'd like to find examples of pom.xml and detailed list of Alfrescos libraries and their versions, but don't know where to go for them.
