Why does Block.lookup throws Exception?
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...

RE: [merlin] merlin + datasources
Posted by Jim Alateras <ji...@comware.com.au>.
I have been able to use the test case to test the DataSourceSelector
component in isolation and that call to select works but in the context
of my application I still get an error.
I have dug a little further and have found that the NPE comes from
CompositeBlock.invoke..as indicated by the stack trace below.
java.lang.NullPointerException
at
org.apache.avalon.activation.appliance.impl.CompositeBlock$BlockInvocati
onHandler.invoke(CompositeBlock.java:274)
at $Proxy3.select(Unknown Source)
at
com.choreoworks.pep.loader.PEPLoader.testDataSource(PEPLoader.java:367)
at
com.choreoworks.pep.loader.PEPLoader.access$000(PEPLoader.java:85)
at
com.choreoworks.pep.loader.PEPLoader$1.run(PEPLoader.java:186)
The line numbers will not match what is in CVS because I have further
instrumented the code. Basically 'service' is null after the call to
model.getExportDirective hence the call to service.getPath throws the
NPE.
ServiceDirective service =
model.getExportDirective( method.getDeclaringClass() );
String path = service.getPath();
It seems that if, in my block.xml file, I replace the "include"
directive with the corresponding "resource" and "component" elements
everything works dandy.
i.e. this doesn't work for me
<include name="jdbc-manager"
id="cornerstone-datasources:cornerstone-datasources-impl" version="1.0"
/>
but this does work for me (with the associated resources)
<component name="jdbc-manager"
class="org.apache.avalon.cornerstone.blocks.datasources.DefaultDataSourc
eSelector" activation="true" />
Furthermore it seems that I am getting the same problem with components
that are imported through the "include" directive (i.e. thread manager,
socket manage etc). When a call through a proxy is made it fails, as
indicated in the stack trace above.
In summary I can work around the problem by removing all "include"
directives from my block.xml and replacing them with the equivalent xml
fragments. I hope this all makes sense ;-).
Finally, I was wondering whether anyone else has experienced a similar
problem.
cheers

Jim:
I took a more careful look at the stack trace that you initially
posted. The NPE is being thrown under the select operation - so the bug
is down in the DefaultDataSourceSelector. I've just update the
cornerstone datasources-impl project to include an empty test case. You
should be able to use this to establish the NPE condition by modifying
the config.xml and invoking selection under the test case.

OK - so the result of the above is that the container you have defined
is exposing itself as a DataSourceSelector service.

First off - your attempting to narrow to a component implementation
instread of the service it exposes. I would have assumed that you would
resolve the DataSourceSelector service from the service manager, then
incoke select on the returned selector.

Umm .. this is a worry - you should not be getting a NPE.
Any chance you could throw together a testcase?

[merlin] merlin + datasources
Posted by Jim Alateras <ji...@comware.com.au>.
I was wondering whether anyone can advice me on how to correctly
configure the datasource component within merlin. This is what I have
tried but I get an exception when I execute the block.
1. In the block.xml I use the include directive
<container name="pep">
:
:
<include name="jdbc-manager"
id="cornerstone-datasources:cornerstone-datasources-impl" version="1.0"
/>
</container>
2. In the config.xml I have the following
<targets>
<target path="/pep/jdbc-manager/manager">
<configuration>
<data-sources>
<data-source name="maindb"
class="org.apache.avalon.excalibur.datasource.JdbcDataSource">
<pool-controller min="5" max="10" />
<driver>org.gjt.mm.mysql.Driver</driver>
<dburl>jdbc:mysql:/localhost/test</dburl>
<user>mysql</user>
<password>mysql</password>
<auto-commit>true</auto-commit>
</data-source>
</data-sources>
</configuration>
</target>
:
:
</targets>
3. In one of my other services, I try to use the datasource like this
DataSourceComponent ds =
(DataSourceComponent)_dsSelector.select("maindb");
But when this service executes I get the following error
java.lang.NullPointerException
at
org.apache.avalon.activation.appliance.impl.DefaultBlock$BlockInvocation

Can anyone see any problems with my usage?
Has anyone used excalibur-datasource/cornerstone-datasources within
merlin?

Just a note - seems that the default goal assumes that 2.4-dev is built
but does not build it if it isn't.
Doing a maven jar:install in jakarta-turbine-2 seems to be getting me to
the point where I can see the errors you concerned about. Ok - I'm still
digging.

RE: Why does Block.lookup throws Exception?
Posted by Eric Pugh <ep...@upstate.com>.
Thanks Stephen,
I think I updated the build.. Thanks for the Reactor code, as multiproject
is failing frequently due to out of memory errors.. I was enjoying all the
benefits of multiplugin, but until the memory holes are patched, I think
just using the reactor directly is the way to go.
I have committed an updated project.xml that includes the copying of the
block.xml file. I believe the same project.xml can be used by the not yet
merlinized components as well as the merlinized components.
As far as the Turbine 2.4 build, yes, the
jakarta-turbine-2/extensions/torque build requires 2.4. Under the reactor
it should realize that the torque extension requires 2.4, and therefore
build it first, and then the torque extension. I am trying to get the
torque code into it's own build so that when I am ready to replace it with
the fulcrum security, it will be more of a drop in replacement. Also, the
torque code forced some ugly build steps on the turbine core! I can foresee
other turbine specific code that would go in extensions as well.
At this point I have the block.xml loading up both the sample Hello
component as well as the Mimetype component!

Re: Why does Block.lookup throws Exception?
Posted by Stephen McConnell <mc...@apache.org>.
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?

RE: Why does Block.lookup throws Exception?
Posted by Eric Pugh <ep...@upstate.com>.
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!

RE: Why does Block.lookup throws Exception?
Posted by Eric Pugh <ep...@upstate.com>.
Also,
I am currently loading a block with a container called 'tutorial' which was
the easist way to load the Appliance for this: appliance:/tutorial/hello...
However, what I think should be happening is that the block.xml in
merlin-hello-tutorial.jar should be auto imported under the name
'tutorial/hello' while the block for turbine should have a container called
'turbine' so any thing would be defined as 'turbine/mimetype'. I looked,
and the block for fulcrum-mimetype-impl-1.0-alpha-4.jar (mouthful!) has a
container called 'test' which I think is wrong..
The mimetype code for fulcrum based on what you did is all checked in by the
way..

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.

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

RE: Why does Block.lookup throws Exception?
Posted by Eric Pugh <ep...@upstate.com>.
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..
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")
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.. Not sure though.. Right now I
just get back a null..
I can commit the code if that helps..

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.
