Problems with Demo App

I discovered an odd occurrence using the sis-webapp demo. I'm running
Tomcat 7.0.53 on Mac OSX Mavericks. I took the approach of modifying
the web.xml file in the source tree (attaching the contents here) and
running mvm clean package to create the war file.

Then I copied the .war file to Tomcat's web apps directory.

When I tried to do a request to the web page I get an error like the
following in the log:

[INFO] Existing qtree index at: [/path/to/qtree/index/dir/] not found.
Creating new index.
ava.io.FileNotFoundException: /path/to/sis-location-config.xml (No
such file or directory)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:120)
        at java.io.FileInputStream.<init>(FileInputStream.java:79)
        at org.apache.sis.services.LocationServlet.init(LocationServlet.java:139)

As you can see below I've changed the parameters in web.xml. I don't
know where it's getting these values from. The default qtree location
wasn't even in the original xml. I added my own. I've never had an
issue like this where Tomcat didn't seem to read context-params. Has
anyone else experienced this?

Thanks,
Greg

FYI, your speculation about the context.xml file was correct. I don't
know how I missed that. I thought I had checked it :-) After changing
the values there, the application works as expected.

Thanks,
Greg

Hello Greg

Unfortunately I'm not familiar with the sis-webapp module. I saw no
developer name in source code or in the module pom.xml file, so I do not
know who to ask... I will ask on the dev mailing list. In the meantime,
I do not know if it can be of any help, but a search for
"sis-location-config" on the source code has show that the path also
appears in the following file, in addition to web.xml:

application/sis-webapp/src/main/webapp/META-INF/context.xml

I hope that sis-webapp has not suffered from the various refactoring
done during the last year...

    Martin
