How to run block built with cocoon-22-archetype-block
Following doc:
http://cocoon.zones.apache.org/daisy/documentation/g1/1159.html
I created a fresh block with:
mvn archetype:create -DarchetypeGroupId=org.apache.cocoon
-DarchetypeArtifactId=cocoon-22-archetype-webapp
-DarchetypeVersion=1.0.0-M4-SNAPSHOT -DgroupId=my.domain
-DartifactId=testwebapp
Using installed local cocoon trunk at revision 480141 build with:
-Dmaven.war.shieldingclassloader=false
java version "1.5.0_06" on MacOSX 10.4.6
Maven version: 2.0.4
While trying either mvn package, mvn jetty:run, mvn jetty6:run
I always get the following error:
[INFO] Scanning for projects...

Any hint to work with block created from archetype ?

I'll invest in that direction this week-end.

As far as my understanding permits, I'll be glad to update what's
existing and propose something as you mention above as soon as I am able
to make it work for myself :)
And by the way thanks for the great work.
Once a 2.2 release will be available, I think the Mavenization and
Spring integration will ease Cocoon adoption a lot.

Ok, did it like:
mvn archetype:create \
-DarchetypeGroupId=org.apache.cocoon \
-DarchetypeArtifactId=cocoon-22-archetype-block \
-DarchetypeVersion=1.0.0-M5-SNAPSHOT \
-DgroupId=ch.extentis \
-DartifactId=testroot
Modify:
src/main/resources/META-INF/cocoon/spring/block.xml
From:
<property name="mountPath" value="/testroot" />
To:
<property name="mountPath" value="/" />
Do not forget:
cd testroot
mvn install
cd ..
Then this block is accessible as "root" sitemap while included in a
webapp such as:
mvn archetype:create \
-DarchetypeGroupId=org.apache.cocoon \
-DarchetypeArtifactId=cocoon-22-archetype-webapp \
-DarchetypeVersion=1.0.0-M2-SNAPSHOT \
-DgroupId=ch.extentis \
-DartifactId=testwebapp
Modify pom.xml to add dependencies on testroot
cd testwebapp
mvn package jetty:run
testroot block is then accessible via http://localhost:8888/

I will try this together with starting testing inter-block protocol
communications. I will certainly start a Block Protocol thread at that
time :)

That is correct. The block servlets are Spring components that are wired
together in a Spring configuration. The block connections are put into a
property map where a key and a component reference are a associated. The
key is used as block name in the block protocol within the block.
As the root webapp not is a Spring component, it is not obvious how to
use the mechanism for the block protocol within it. I started to
implement another protocol that would make it possible to call blocks
from the root sitemap using the block servlets component identifier, but
I have not found the time to finish it.
It is also possible to access static resources from a block using the
blockcontext protocol. It is however not the recommended way as a block
is intended to be an isolated unit that only should be accessed through
its "public" API in form of the block protocol. The blockcontext
protocol is more intended for internal use in Cocoon and for setting up
the blockcontext property i the block servlet configuration.
One can also use a block for the "root" sitemap in this scenario
everything is a block. For the moment I would say that this is the
recommended way for those testing the blocks fw.

I don't know enough about the block archetype to answer the rest of your
questions.

1. Webapp
Sorry if I have introduced some confusion by talking of webapp
"testwebapp" in a thread titled "How to run block...". I did that test
while lacking to run block directly...
In the context of the web application root "testwebapp" I created with
cocoon-22-archetype-webapp I did not manage to get result from the
testblock in any other way. Given what I read at:
It seems that block protocol is not available from root webapp according to:
http://www.nabble.com/Configuring-BlockServlets-via-properties-and-sitemap-reloading-for-blocks-t2450880.html
Or do I miss something ?
2. Block
Now I finally got block running directly using:
mvn package cocoon:deploy jetty:run
After that the block name "testblock" is available at:
http://localhost:8888/testblock/
Is this the right way to proceed ?
Then in my testblock pom.xml I modified the cocoon-deployer-plugin from
its initial state provided by the archetype:
<plugin>
<groupId>org.apache.cocoon</groupId>
<artifactId>cocoon-deployer-plugin</artifactId>
<version>1.0.0-M2-SNAPSHOT</version>
</plugin>
to:
<plugin>
<groupId>org.apache.cocoon</groupId>
<artifactId>cocoon-deployer-plugin</artifactId>
<version>1.0.0-M2-SNAPSHOT</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>deploy</goal>
</goals>
</execution>
</executions>
</plugin>
then the block can simply be run as:
mvn package jetty:run
I am not particularly knowledgeable with that kind of Maven
configurations, its just that its was like this a couple of weeks ago :)
Feedback are welcome as I plan write some "Getting started"
documentation and would avoid writing wrong tips.
TIA,
Patrick

This shouldn't be necessary to get some result from your testblock as it is
automaticially mounted.

Indeed blocks-fw-impl was missing !
I have tested referencing the a testblock from a testwebapp as follow:
Created testblock:
mvn archetype:create -DarchetypeGroupId=org.apache.cocoon
-DarchetypeArtifactId=cocoon-22-archetype-block
-DarchetypeVersion=1.0.0-M4-SNAPSHOT -DgroupId=ch.extentis
-DartifactId=testblock
Installed testblock
Created testwebapp
mvn archetype:create -DarchetypeGroupId=org.apache.cocoon
-DarchetypeArtifactId=cocoon-22-archetype-webapp
-DarchetypeVersion=1.0.0-SNAPSHOT -DgroupId=ch.extentis
-DartifactId=testwebapp
Added testblock dependency to testwebapp POM:
<dependency>
<groupId>ch.extentis</groupId>
<artifactId>testblock</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
Added the following to testwebapp sitemap:
<!-- Reference any block by its blockContextURL / mount path ? -->
<map:match pattern="*/**">
<map:mount uri-prefix="{1}" src="blockcontext:/{1}/"/>
</map:match>
Then after
mvn package jetty:run
I could get testblock answer from localhost:8888/testblock/
Is this the right way to proceed for referencing blocks from a webapp ?
I just discovered blockcontext: syntax lately.

please try (IIRC, the only thing you forgot was the blocks-fw-impl dependency)

Documentation is always welcome! It would be great to have a second getting
started document ("Getting started in 5 minutes") that explains how to connect
to another block and how to use inheritance.

What else can a user do to help ? Updating related documentation ? I'll

I have read more docs:
Tutorial: Creating, extending and running a block
http://cocoon.zones.apache.org/daisy/documentation/796.html
BD: Tutorial: Using the block deployer to create a Cocoon web application
http://cocoon.zones.apache.org/daisy/documentation/797.html
But it does not help me running blocks created with
cocoon-22-archetype-block 1.0.0-M4-SNAPSHOT
I have added:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.1</version>
<configuration>
<archive>
<manifestEntries>
<Cocoon-Block-Name>${pom.artifactId}</Cocoon-Block-Name>
</manifestEntries>
</archive>
</configuration>
</plugin>
Removed / Re-added cocoon-deployer-plugin
Updated maven-jetty-plugin from 6.0.0beta10 to 6.0.0rc4
Added a BlockServlet to my
META-INF/cocoon/spring/myblock-application-context.xml file:
<bean
id="com.mydomain.block" class="org.apache.cocoon.blocks.BlockServlet">
<property name="mountPath" value="/myblock"/>
<property name="servletClass"
value="org.apache.cocoon.sitemap.SitemapServlet"/>
<property name="blockContextURL"
value="blockcontext:/myblock/"/>
</bean>
and finally obtains a:
java.lang.ClassNotFoundException: org.apache.cocoon.blocks.BlockServlet
Is there a cocoon-22-archetype-block working with the current trunk ?
TIA,
Patrick
