Doubts on JCR-RMI

[rcortesr]

Hi,

For to use JCR-RMI I must install jackrabbit? How I can do it?
There is some example for to add nodes in de repository using RMI?

I have another doubt: why it appears the following error when execute my code?

ERROR:
[size=75]Exception in thread "main" java.lang.NullPointerException
   at org.alfresco.jcr.item.PropertyImpl.checkSingleValued(PropertyImpl.java:630)
   at org.alfresco.jcr.item.PropertyImpl.setPropertyValue(PropertyImpl.java:509)

MY CODE:
[size=75]Node facturas = myNode.addNode("fac:facturas", "cm:folder");
            facturas.setProperty("cm:name", "Facturas");
               facturas.setProperty("cm:description", "");
              
               Node fac1 = facturas.addNode("fac:entry1", "fac:factura");
               fac1.setProperty("cm:name", "Factura1");
               fac1.setProperty("cm:description", "pruebaaaaa");
               fac1.setProperty("cm:title", "mi primera factura");
               fac1.setProperty("cm:content", "hola holaaaaaaaa");
               fac1.setProperty("fac:NIF_proveedor", "13434");[/size]

fac is the prefix of my custom model of content. The problems appears when I set a custom property.

Thanks.

No, you don't need to install Jackrabbit.  You do need a Jackrabbit jar though.

Have you seen http://wiki.alfresco.com/wiki/JCR-RMI_Extension ?

The exception generally indicates you haven't registered a model (which declares the fac namespace, facturas type and NIF_proveedor property).

Hi,

I believe that I have registered the new model because I can add new documents of the type facturas. And I can set the common properties (name, title, description…).
The problem is to set the customized properties.

Somebody can help me?

This line is looking for the property description in the model.  It's failing with a NPE because the property does not exist.
