Build the source code
>cd jackrabbit

Take this project as example, jackrabbit/jackrabbit-webapp. I just make it working ASAP, and them check the configuration.
Here is the web.xml file content.
<listener>

        <description>
            Repository servlet that starts the repository and registers it to JNDI ans RMI.
            If you already have the repository registered in this appservers JNDI context,
            or if its accessible via RMI, you do not need to use this servlet.

<description>
This servlet provides other servlets and jsps a common way to access
the repository. The repository can be accessed via JNDI, RMI or Webdav.

          <description>
            If this is set, the RepositoryAccessServlet expects a Repository in the ServletContext
            attribute having this name. This allows servlets of this module to be used with repositories
            initialized by the jackrabbit-jcr-servlet module utilities.

<description>
The servlet used to remote JCR calls over HTTP.

<servlet-class>org.apache.jackrabbit.j2ee.JcrRemotingServlet</servlet-class>
<init-param>
<param-name>missing-auth-mapping</param-name>
<param-value></param-value>
<description>
Defines how a missing authorization header should be handled.
1) If this init-param is missing, a 401 response is generated.
This is suitable for clients (eg. webdav clients) for which
sending a proper authorization header is not possible if the
server never sent a 401.
2) If this init-param is present with an empty value,
null-credentials are returned, thus forcing an null login
on the repository.
3) If this init-param is present with the value 'guestcredentials'
java.jcr.GuestCredentials are used to login to the repository.
4) If this init-param has a 'user:password' value, the respective
simple credentials are generated.

<servlet-mapping>
<servlet-name>JCRWebdavServer</servlet-name>
<url-pattern>/sillycat/*</url-pattern>
</servlet-mapping>

Not only the classes, but also the properties file bootstrap.properties
repository.home=d://work/easy/easywebdavserver/sillycat
repository.config=d://work/easy/easywebdavserver/sillycat/repository.xml
repository.name=sillycat.repository

Copy the logback.xml to resources directory.

I change the method getConfig() in RepositoryAccessServlet.java, make it read the properties file from classpath
InputStream in = getServletContext().getResourceAsStream(bstrp);
                // check if it's a class path properties
                if(in == null){
                in = this.getClass().getResourceAsStream(bstrp);
                }

Make the same changes to RepositoryStartupServlet.java
private boolean configure() throws ServletException {
// check if there is a loadable bootstrap config
Properties bootstrapProps = new Properties();
String bstrp = getServletConfig().getInitParameter(
INIT_PARAM_BOOTSTRAP_CONFIG);
if (bstrp != null) {
// check if it's a web-resource
InputStream in = getServletContext().getResourceAsStream(bstrp);
// check if it's a class path properties
            if(in == null){
            in = this.getClass().getResourceAsStream(bstrp);
            }
...snip...

And I do not think I need RMI/JNDI support, so I create repository in RepositoryStartupServlet.java and put the repository itself in Servlet Context, from RepostoryAccessServlet, I read it from the servlet context.
public void startup() throws ServletException {
if (repository != null) {
log.error("Startup: Repository already running.");
throw new ServletException("Repository already running.");
}
log.info("RepositoryStartupServlet initializing...");
try {
if (configure()) {
initRepository();
registerContext();
registerRMI();
registerJNDI();
}
log.info("RepositoryStartupServlet initialized.");
} catch (ServletException e) {
// shutdown repository
shutdownRepository();
log.error("RepositoryStartupServlet initializing failed: " + e, e);
}
}
...snip...
private void registerContext() throws ServletExceptionWithCause {
try {
getServletContext().setAttribute("sillycat.Repository", repository);
} catch (Exception e) {
throw new ServletExceptionWithCause(
"Unable to bind repository in context", e);
}
}
