Package org.apache.jackrabbit.j2ee

Class RepositoryStartupServlet

  • All Implemented Interfaces:
    Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
    public class RepositoryStartupServlet
extends AbstractRepositoryServlet
    The RepositoryStartupServlet starts a jackrabbit repository and registers it to the JNDI environment.

    Note: if a bootstrap-config init parameter is specified the servlet tries to read the respective resource, either as context resource or as file. The properties specified in this file override the init params specified in the web.xml.

    Setup Wizard Functionality
    When using the first time, the configuraition can miss the relevant repository parameters in the web.xml. if so, it must contain a bootstrap-config parameter that referrs to a propertiy file. This file must exsit for proper working. If not, the repository is not started.
    If the servlet is not configured correctly and accessed via http, it will provide a simple wizard for the first time configuration. It propmpts for a new (or existing) repository home and will copy the templates of the repository.xml and bootstrap.properties to the respective location.
