Re: Why does Block.lookup throws Exception?

Eric:

Have taken a look at the component build. For the configuration component and the mimetype component you need to include a parent project defintion that includes a resource definition to copy the block.xml into the appropriate directory (otherwise the unit test will locate the block.xml). I have attached a merlin-project.xml and a maven.xml that I put into my the /fulcrum/configuration and /fulcrum/mimetype directories, updated the <extend> tag in the impl subdirectories and everything works fine.

Was not able to build security or osworkflow (details included in earlier email).

Finally - it looks like there may be something odd going on inside the turbine 2.4 build as its trying to resolve 2.4 while building 2.4. In particular jakarta-turbine-2/extensions/torque is trying to download 2.4-dev as part of the build and 2.4-dev does not appear to exist, and 2.4-dev is the main build target. Feels like something recursive?

I am committing now..  I actually realized my unit test for the
MerlinComponentService had the same issue, so maybe you can look at it
instead..

/src/conf/test/merlin is the merlin config stuff.

/src/test/org/apache/turbine/services/avaloncomponent is the path to the
unit test..

We need IRC!

That would be great, because I assume that Merlin will

hollar if there is a

config error etc, I basically catch teh Exception and throw a
NestableRuntimeException.

Yep - asssumption is correct.

Next question..

How do I get the darn mimetype component to load..

<container name="fulcrum"> <classloader> <classpath> <repository> <resource id="fulcrum:fulcrum-mimetype-api"

version="1.0-alpha-4"/>

       <resource id="fulcrum:fulcrum-mimetype-impl"
version="1.0-alpha-4"/>
     </repository>
   </classpath>
 </classloader>
 <component name="mimetype"
class="org.apache.fulcrum.mimetype.DefaultMimeTypeService"/>

</container>

Notice I bumped the versions, you need to build locally and

deploy.. When

I do a lookup, I do this:
(MimeTypeService)merlin.lookup("fulcrum/mimetype")

Don't have the code in front of me just at the moment but you
should be
using "/fulcrum/mimetype" (i.e. an absolute path).  Remember
that your
invoking this from the root container - unlike the testcase where you
can conviniently use a relative reference to the test container.

I also tried
(MimeTypeService)merlin.lookup("mimetype")
Part of me feels like though that the block info included in

the impl jar

should mean I don't need to declare this..

You don't need to do this.  If the <component> is declared
Merlin will
default to activating component on container deployment.

Not sure though..  Right now I
just get back a null..

That's not good.  You should actually be getting an
IlegalArgumentException.

I can commit the code if that helps..

Yep - what's the directory path that your committing to?

Stephen.

Hi all,

I am working on integrating the Merlinized Fulcrum Mimetype

component, and
noticed that this throws an exception:
Block root = m_kernel.getRootBlock();
     return root.locate(path);
Why doesn't it throw a MerlinException or ComponentException? Or RuntimeException? It seems like just Exception isn't very

useful...

I agree.

There is a NoProviderDefinitionException declared in the
activation API.
I think this will cover the majority of concerns.  I'll do
some playing
around and see what we can come up with.

Stephen.
