New aspect is found in javascript but not java

kbpair

I have created a new aspect (schemaValidation) and I can apply the aspect to content via the gui and javascript.

However if I try to check for this aspect in Java by building the QName I get an error saying:

Namespace prefix evg is not mapped to a namespace URI

Of course I use the namespace prefix in the javascript without any error. What am I missing?

here is my model file:

<?xml version="1.0" encoding="UTF-8"?>

            <property name="evg:message">

            </property>
            <property name="evg:schema_node_ref">

            </property>
            <property name="evg:schema_url">

            </property>
         </properties>
      </aspect>
   </aspects>

</model>

and I use the following in my Java class

DynamicNamespacePrefixResolver nsRslvr = new DynamicNamespacePrefixResolver();
QName aspectQN = QName.createQName("evg","schemaValidation", nsRslvr);

I am hoping i just missed something simple. Any help is appreciated.

I have also tried passing the namespace
QName aspectQN = QName.createQName("http://www.evergreeninvestments.com/vocab','schemaValidation");
and get the following error. I am really stumped and will take any suggestions.

kevinr

and I use the following in my Java class

DynamicNamespacePrefixResolver nsRslvr = new DynamicNamespacePrefixResolver();
QName aspectQN = QName.createQName("evg","schemaValidation", nsRslvr);

You should be using the NamespaceService itself - the DynamicNamespacePrefixResolver will not resolve to your model unless you construct it using the NamespaceService anyway.

Use Spring to bind in the NamespaceService along with your other services, then you can do this:

QName aspectQN = QName.createQName("evg","schemaValidation", this.namespaceService); 
‍‍‍

Thanks,

Kevin

Thanks for the note on how to properly search for namespaces, unfortunately after the changes I still have issues. The prefix 'evg' is resolved to the proper namespace, as it was being done in my previous post, but the aspect is invalid.

Of course in the javascript code I check to see if the document has this aspect and the code works without any errors.

I am getting really frustrated - I am evaluating Alfresco for my current project and have to present my findings in a day and a half. So far the 'simple' assignment of validating the content against a schema is causing all kinds of issues.

So if anybody can help with this I would really appreciate it.

davidc

Could you restate your issue please?

You say the javascript works, but the stack trace is from executing a script. You also say that the namespace prefix is not mapped correctly in java, but then say it is.

Please post your line of java code where the exception is raised.

kbpair

Sorry for being unclear. In my effort to get this working I tried to use the DynamicNamespaceResolver which led to the namespace mapping issue. The real issue is that my custom aspect is 'invalid' when accessed via the java code.

The java code is called from a script which may also be leading to some confusion.

After creating my custom aspect I run this javascript to set a property:

var metwest_schema_nd = 'workspace://SpacesStore/90329581-c8c8-11db-900a-31d3e5b11671';
// example of hasAspect() API functions
if (document.hasAspect("evg:schemaValidation"))
{
document.properties["evg:schema_node_ref"] = metwest_schema_nd;
document.save();
}

This script runs without any issues - the document has the aspect and the property is set.

Then I call the next script (which in turn calls my java class)

//create Action
var act = actions.create("xmlvalidator");
act.execute(document);

As you can see there is really nothing in this script and the resulting error is actually from the java class.

Why is the aspect valid in javascript but not in java?

That is odd.

Can you:

1) enable log4j.logger.org.alfresco.repo.dictionary.DictionaryDAO=info in log4j.properties (this will give some info on which namespaces and models are loaded on startup of the repository)

2) provide the spring configuration for your action bean

3) provide the value of aspectQN.toString()

I'm assuming the exception comes

if (nodeService.hasAspect(actionedUponNodeRef, aspectQN)) {‍

It appears to be working now.

The namespace did not match the namespace being loaded.

The last QName code I was using was incorrect, as it was setting the prefix as the URI. Therefore it did not find the aspect.

thanks for your help.
