as mentioned in previous posts of mine to this list, I have written a
class that implements the org.dspace.identifier.IdentifierProvider
interface for DSpace 3.0. Now that this is complete and I have
successfully set up 3.0-rc1, I'm looking to use my own class instead of
the default one. How do I do this?
If you're adding a new identifier type, just include its bean
definition. If you're providing a different implementation of Handles
then I think you'd need to comment out the stock Handle provider bean.
You mean include its name in the identifier-service.xml? Well that's
what I did right? (See the enclosed file). I'm afraid I don't quite
understand what you mean by 'include bean definition' and how to do so.
Still, the way I try to inject the bean leaves me with a
ClassNotFoundException, even though my JAR is in the CLASSPATH and in
[dspace]/lib. Do I have to somehow tell DSpace/Spring explicitly where
to find it?
I have set the class attribute to the package+name of my class for the
respective bean in both
[dspace-src]/dspace-api/target/classes/spring/spring-dspace-core-services.xml
and
[dspace-src]/dspace/target/dspace3.0-rc1-build/config/spring/api/identifier-service.xml
(on this note, why does the same stuff get defined in these two
different files?)
I created a new spring-dspace-addon-identifier-services.xml and placed
it in [dspace-src]/dspace-api/src/main/resources/spring, whence it
will be copied to [dspace-src]/target/classes/spring/ by Maven. That
gets it tucked into lib/dspace-api-VERSION.jar where Spring can find
it.
I checked out the latest version of the code from git this morning and
the file you mentioned is not included.
I defined bean properties for things that shouldn't really be in the
code, but which are unlikely to change -- they're just externalized
constants. Things that each installation would need to change are
fetched from [dspace]/config/** so that they're easy to adjust.
I should say that I'm still early in development and had not actually
installed and run this very incomplete code until just now. But the
XMLUI starts without complaint by Tomcat.
Running 'ant update' and restarting Tomcat results in an error, the
Tomcat log says:
<<Cannot find class [de.mannheim.ids.pid.dspace.IDSIdentifierProvider]
for bean with name 'org.dspace.identifier.IdentifierService' defined in
file [/var/opt/ds
pace/config/spring/api/identifier-service.xml]; nested exception is
java.lang.ClassNotFoundException>>
... and a lot more, all related to the problem that the class cannot be
found.
The class is in the classpath and building worked, too. I presume I did
something wrong with the Bean definition (I'm very very new to the
Spring framework), right? The identifier-service.xml is attached. Also,
what annotation do I have to set in the code of my class? Basically I
adopted all the @Autowired/@Required/... annotation from
IdentifierProviderImpl.java.
I found that declaring any autowiring on my provider caused circular
reference problems when Spring instantiates the provider. I left
@Required on the property setters and took out both @Autowired and
<bean autowire>. The IdentifierService gets itself autowired with a
list of providers and then injects itself into each as parent.
Another confession: I'm also quite new to Spring, so anything I do
with it that works probably owes a lot to luck.
Here's my bean declaration:
... and that's for the spring-dspace-addon-identifier-services.xml,
right? :)
