Hello All,
I want to know that is it possible to create custom attributes in alfresco without restarting the alfresco server.
If yes then how can we do that.

Thanks.

I think you can upload custom model with aspects and aplay them to the nodes.

Can you please elaborate on this.
Suppose i have a custom model.xml file and have created an entry of it in web-client-config-custom.xml and context.xml file.
Now how can i make these attributes(in custom model.xml) visible in Alfresco without any server restart.

savic_prvoslav

this is really easy all you need is hire http://wiki.alfresco.com/wiki/Step-By-Step:_Creating_A_Custom_Model

hope it helps.

In Alfresco Enterprise you can restart sub systems without restarting the server. If you are using Alfresco Enterprise see http://wiki.alfresco.com/wiki/JMX.

Hi @ savic,

I have gone through the link you have mentioned.
In the steps to create a new custom model, i followed till the 5 step i.e. make an entry of new content moedl in web client xml file.
But did'nt got the idea about the 6&7 steps.
Can you please expain them.

Thanks,

savic_prvoslav

You should first tell me what are you going to do and why you need it.

send me what you have.

I will probably send you the rest .

this approach is faster then me explaining what is on wiki if it has no connection with what you need.

hi,
Actually i have created a JSF based application to create the custom document attributes(metadata) in alfresco.
This utility creates a new model.xml and context.xml file and modifies the existing web-client-config-custom.xml file in "alfresco\tomcat\shared\classes\alfresco\extension" folder.
But to make the custom attributes visible in alfresco, i need to restart my alfresco server every time.
So is their any way to make them appear in alfresco without restarting the server.

savic_prvoslav

as you saw in the wiki you can upload model( with aspects or other) into alfresco , create your application that way to modify documents inside alfresco repo.

Hi,
I hae created the model file as given in the link "http://wiki.alfresco.com/wiki/Dynamic_Models" using web service API.
But the default value to the "Model Active" property to "No" so the model does not become active into the repository.
Can anybody tell me how to set the value to this property "YES" using API coding.

Thanks,

savic_prvoslav

ContentModel.PROP_MODEL_ACTIVE needs to be set. You can do this via api.

prateekgoyal

Hi,
Can you please tell me how to do this sing web service API. Actually i searched on the net, all the methods given are done using other alfresco api's and i was using web service api.

Thanks,

savic_prvoslav

you can use web service api http://wiki.alfresco.com/wiki/IngresTutorial_Alfresco_Web_Service_API_for_Java

so when you create your document ( model) set property that I have give to you. This should do the trick.

prateekgoyal

Hi,
actually i have tried that,in Constants class in web service api i didnt find any property like PROP_MODEL_ACTIVE.
So that is the problem with me.

savic_prvoslav

can you send me your code?

prateekgoyal

Here is the code that i'm using.
In this if the file already exist in the path mentioned then this code will first delete that file and upload the new one otherwise creates a new file onto the path mentioned.

savic_prvoslav

have you tried /contentProps[1] = Utils.createNamedValue(ContentModel.PROP_MODEL_ACTIVE, true);

prateekgoyal

yes, it is giving the error as "ContentModel.PROP_MODEL_ACTIVE cannot be resolved"

savic_prvoslav

also contentmode.prop… is actually {http://www.alfresco.org/model/content/1.0}modelActive

prateekgoyal

Actually "Utils.createNamedValue()" accepts string value as parameters so i cannot supply ""{http://www.alfresco.org/model/content/1.0}modelActive',true " to this function.

savic_prvoslav

hm, well I do not think I have idea how to help you
