Building portlets with Jetspeed 2.0

If you are looking at open source based portlet 2.0 development, then a good starting point could be jetspeed 2.0

You can create a maven project with the custom archetype of jetspeed by following similar syntax as below.

mvn org.apache.maven.plugins:maven-archetype-plugin:2.0-alpha-4:generate -DarchetypeGroupId=org.apache.portals.jetspeed-2 -DarchetypeArtifactId=jetspeed-archetype -DarchetypeVersion=2.2.0 -DartifactId=hello -Dpackage=com.springboard -DgroupId=com.springboard -Dversion=1.0-SNAPSHOT

You might come across an exception something like this

the fix is that db plugin dependency is missing, I got rid of it by adding the dependency.


org.apache.portals.jetspeed-2
jetspeed-db-tools
${org.apache.portals.jetspeed.version}



Do not forget to add repository (might be optional).
