General FAQ

How can I reset all Nuxeo data?

Simply remove the nxserver/data folder from Nuxeo (in the EasySOA package, Nuxeo is filed under the serviceregistry folder).

Enabling remote debugging

Open bin/nuxeo.conf and uncomment the "DEBUGGING" options line:

        # Sample JPDA settings for remote socket debugging
        JAVA_OPTS=$JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n

You can switch suspend=n to suspend=y if you want to monitor Nuxeo right from the start (Java will wait for you to connect with Eclipse before to start Nuxeo).

JSF FAQ

String concatenation in EL (Expression Language)

It is not done by "+" but by either by putting them along each other in an EL expression, [using <c:set var="s" value="${s1} ${s2}"/> beforehand] (http://stackoverflow.com/questions/296398/concatenate-strings-in-jsp-el), or defining a [custom concat() function] (http://stackoverflow.com/questions/2192759/concatenate-strings-in-jsf-jsp-el-and-javascript).

JAX RS

REST HOWTO

• How to return collections in jaxrs / jaxb / cxf (without going to Spring conf) : create a strong-typed collection class ex. ExchangeRecordCollection See http://dhruba.name/2008/12/08/rest-service-example-using-cxf-22-jax-rs-10-jaxb-and-spring/#comment-781 NB. resteasy provides additional non-standard annotations for that : @Wrapped http://stackoverflow.com/questions/6192389/root-element-name-in-collections-returned-by-resteasy

• How to handle a reference to another object not as an object but as its id : XmlJavaTypeAdapter See http://docs.oracle.com/javase/6/docs/api/javax/xml/bind/annotation/adapters/XmlJavaTypeAdapter.html

• How to automatically convert java objects to JSON with a JAX RS service : Some annotation need to ba added on the method :

@GET
@Path("/getExchangeRecordStorelist")
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public StoreCollection getExchangeRecordStorelist() { ...

@Produces to tell that the returned type can be a json string. The returned java object, here StoreCollection must have some annotations :

@XmlRootElement
public class StoreCollection {

    private Collection<ExchangeRecordStore> stores;
    ...
    @XmlElement(name="ExchangeRecordStore")
    @XmlElementWrapper(name="stores")
    public Collection<ExchangeRecordStore> getStores() {
        return stores;
    }
}
