Hi, Nutch initializes plugins multiple times and so any expensive initialization procedures are being executed more than once. For example plugin needs to make a connection to the data base. Each instance of the plugin will have to create that connection, which leads to plugins spending lots of time making connections (I'm using db connections only as an example). Ideally a connection pool must be created and shared between instances of a given plugin.
Is there any way to share objects (e.g. connection pools) between instances of the plugin? JavaDoc for org.apache.nutch.plugin.Plugin states: "A possible usecase of the <code>Plugin</code> implementation is to create or close a database connection." I have tried this code in Plugin's startUp code: ((MyPlugin) getDescriptor().getExtensions()[j].getExtensionInstance()).setExpeciveStuff( x ); but calling getExtensionInstance leads to StackOverflowException Regards, zm
