Issues configuring repositoryURI or homeDir

                 Key: JCR-2745
                 URL: https://issues.apache.org/jira/browse/JCR-2745
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: 2.1.1
         Environment: Windows 7 64 bit, JBoss 5.1.0.GA, Sun JDK 1.6.0_18
            Reporter: Sverker Abrahamsson

I've encountered an issue when upgrading jackrabbit to 2.1.1 from 1.x version. Earlier I used
to set homeDir parameter to ${jboss.server.data.dir}/jackrabbit for the repository to be placed
in $JBOSS_HOME/server/default/data/jackrabbit. I see that homeDir is now deprecated and repositoryURI
should be used instead. However, I can't succeed with placing it anywhere else than $JBOSS_HOME/bin/jackrabbit
which is where it ends up with repositoryURI = jcr-jackrabbit://jackrabbit

I've used a debugger and found that the issue occurs in org.apache.jackrabbit.core.RepositoryFactoryImpl.getRepository(Map
parameters) where the repository uri is parsed by creating a URI object at line 81 (source
code from jackrabbit 2.1.1).

First attempt, if I set repositoryURI to "jcr-jackrabbit://../server/default/data/jackrabbit"
then ".." is interpreted as the authority and "/server/default/data/jackrabbit" as the path,
instead of it both as relative path. This doesn't seem to be the right behavior as I can read
from jdk javadoc.

Second attempt, setting repositoryURI to "jcr-jackrabbit://${jboss.server.data.dir}/jackrabbit"
then that is expanded to "jcr-jackrabbit://D:\java\jboss-5.1.0.GA\server\default\data/jackrabbit"
which cause a URISyntaxException with message "Illegal character in authority at index 17".

Third attempt, setting repositoryURI to "jcr-jackrabbit://D:/java/jboss-5.1.0.GA/server/default/data/jackrabbit"
cause D: to be parsed as authority and the rest as path.

Fourth attempt, using the old depreciated homeDir config parameter the repository is instanciated
but the webapp throws exception that repository startup configuration is invalid. It is still
creating it's temp directory under ${jboss.home}/bin/jackrabbit/

Fifth attempt, trying to create repository from webapp. If repository home directory is specified
as jackrabbit then it's created under ${jboss.home}/bin/jackrabbit/. If specified as d:/java/jboss-5.1.0.GA/server/default/data/jackrabbit
then the following 

 11:58:14,220 INFO  [STDOUT] 13.09.2010 11:58:14 *INFO * Installer: Creating new repository

repository home ':/java/jboss-5.1.0.GA/sever/default/data/jackrabbit' but does not exists
(Installer.java, line 160)

Sixth attempt, copying the repository created by webapp from $JBOSS_HOME/bin/jackrabbit to
$JBOSS_HOME/server/default/data/jackrabbit cause the webapp still to throw exception that
repository startup configuration is invalid

Seventh attempt, after googling on how URI class works on windows I find a workaround to set
repositoryURI to jcr-jackrabbit:/D:/java/jboss-5.1.0.GA/server/default/data/jackrabbit where
it suceeds to instansiate the repository. Webapp still throws exception "Repository startup
configuration is not valid". 

Eight attempt, debugging shows that RepositoryStartupServlet expects bootstrap.properties
in $JBOSS_HOME/bin/jackrabbit so it's copied there. It does not work to use the macro ${jboss.server.data.dir}
but using absolute path for repository.home and repository.config works

Ninth attempt, changing bootstrap-config parameter in web.xml to ${jboss.server.data.dir}/jackrabbit/bootstrap.properties
works fine. However it's anoying to have to use absoute paths in bootstrap.properties since
the jboss macros aren't expanded, neither does repository.config=${rep.home}/repository.xml

Tenth attempt, removing repository.home and repository.config from bootstrap.properties and
setting them as init parameters in web.xml works fins, then ${jboss.server.data.dir} is expanded
properly. $rep.home} doesn't work for repository.config but that was expected.

Suggested actions to solve this issue:
1. Document how to set repositoryURI including the quirk on Windows, I haven't found anything
regarding this parameter on jackrabbit website
2. In org.apache.jackrabbit.core.RepositoryFactoryImpl.getRepository(Map parameters) change
line 81 to the following which will solve the issue of \ in path names on windows when ${jboss.server.data.dir}
is expanded:

URI uri = new URI(parameter.toString().trim().replaceAll("\\", "/"));

3. In org.apache.jackrabbit.j2ee.RepositoryStartupServlet.configure() expand macros when the
properties are loaded. I believe the jboss platform properties are availible from System.getProperties()
but not sure. I believe this is relevant for other platforms as well.

4. I think there may be nessary to identify why creating repository from the webapp doesn't
work according to the error messages above, I believe this is also and issue with URI but
I haven't analysed if further.

This issue may be related to JCR-2729
