About "Referenced file contains errors" for ironjacamar datasources

The last few days an error have started popping up during validation of all our existing JBoss archetypes and examples.

The error you will see in Eclipse problems view will be:

Referenced file contains errors (http://docs.jboss.org/ironjacamar/schema/datasources_1_0.xsd).
        For more information, right click on the message in the Problems View and select "Show Details..."

on various *-ds.xml files.

The cause of this error is that the IronJacamar project moved their xsd’s and rest of their content to http://ironjacamar.org back in June 2013.

I’m sorry for that inconvenience, but do not despair - the solution is here.

Solution

For now we have requested that the content will be restored to make this true but annoying error to go away without you having to do anything.

But until that is fixed you can also fix it locally by using the updated ironjacamar url/namespace in your .xml files:

Change this:

<datasources xmlns="http://www.jboss.org/ironjacamar/schema"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.jboss.org/ironjacamar/schema http://docs.jboss.org/ironjacamar/schema/datasources_1_0.xsd">

to

<datasources xmlns="http://www.ironjacamar.org/doc/schema"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.ironjacamar.org/doc/schema http://www.ironjacamar.org/doc/schema/datasources_1_0.xsd">

Basically replacing http://www.jboss.org/ironjacamar/schema with http://www.ironjacamar.org/doc/schema. The namespace name changes, but otherwise the content/semantics should stay the same.

Why this validation errors have not shown up before we are still looking into and I’ll let you know when we have that answer.

For now just live with the validation error for a few days or update your xsd files to use the new namespace.

Again, sorry for the inconvenience.

Despite this - do Have fun!
