Load order of AMPs

hbf — Thu, 01 Nov 2007 17:16:52 GMT

Hi there,I need advice on loading AMPs in the right order. I have a AMP B that depends on A (as B needs a model from A) and I need to make sure that A gets loaded before B. How can I do this?The reason I ask is that I have an installation of Alfresco on MacOS X which starts up fine but the identical

Hi,

Do you have a module.depends.XYZ entry in your module.properties file? (Relevant Wiki page)

Outch! I should have checked the wiki first (I could have sworn to have read everyting there). Very sorry.

But your reply hit the nail on the head: It's working like a charm now.

Thank you Derek!

That's OK. Sometimes these things don't work as expected ( ops: ), so it's good to know it's sorted it.

Strange, I don't know why but it does not work anymore.

I am using a fresh install of r1207 of Alfresco SVN and see in the deployed alfresco.war:

Notice from the last line that Alfesco tries to access ec (with is from ExternalContent) but apparently hasn't loaded it.

If I enable the debug logger for ModuleServiceImpl I do not get any additional output (it's like above).

Any ideas what this could be? It worked one (but it also did work without the module.depends on another machine).

Thanks,

Can you post that model definition file?

Re: Load order of AMPs

hbf — Thu, 29 Nov 2007 17:36:15 GMT

After debugging Alfesco, I observed that the modules get compiled first (via CompiledModel.java) before the whole dependency process (see ModuleComponentHelper.java) gets invoked and the modules are actually started.

The compilation is triggered by the bean loading mechanism and was, in my case, in exactly the wrong order (not corresponding to the module depencies). Having realized that the bean load order causes the problem, I added a depends-on attribute to the bean loading the model of my module B (that needs A to be loaded first). That solved it:

 <bean id="blablaA" parent="dictionaryModelBootstrap" depends-on="blablaB"> <!– was: depends-on="dictionaryBootstrap"  –>
  <property name="models">
   <list>
<value>alfresco/module/org.mycompany.module.foo/model/fooModel.xml</value>
   </list>
  </property>
 </bean>‍‍‍‍‍‍‍

Either Alfresco should take care of loading the beans in the right order or this needs to be documented.

Regards,
Kaspar

Hi,

Any update on this ? I have exactly the same problem. The work around suggested by Kaspar is working for me too Thank you for sharing it !

My version of Alfresco : Alfresco started (Community Network): Current version 2.9.0 (dev 654) schema 113

But is this a bug ? It looks like I would say 😉 I've quickly searched the Alfresco's Jira but did not find anything about this.

Shoud we fill a Jira for it ? if not, the documentation of modules dependencies should be updated…but I really think it is a bug since the depends properties in module.properties is here to tell Alfresco which module to load before others (if I didn't miss something).

Thank you

Re: Load order of AMPs

zoe — Mon, 01 Aug 2011 20:43:13 GMT

I agree that the module.properties module.depends should also set the loading order. I have two modules A & B where I want to overwrite a bean defined in A in B (I want the bean defined in B to be loaded last so that it's properties are the ones used). But, even though I put that module B depends on module A, the bean from module A was loaded last and so I was unable to overwrite it. I cannot fix this issue by using the spring feature “depends-on” because I’m totally overwriting a bean to change a property value but using the same implementation class. The only way I could get module B to overwrite a bean defined in module A was to renamed module B to come before A alphabetically.

update: this trick did NOT work for my linux deployment, only for windows. No matter what I rename my module to, the load order stays the same, so I am unable to overwrite any beans
