Configuration for frontend cannot be loaded

[tomas-knap]

UnifiedViews 1.3.0

SWC is trying to create debian package from ODN/UV, but they have problems with frontend - loading the conf. From the log, it seems that it cannot find property platform, but as can be seen below, the property is there. This is rather urgent, because the package must be ready by end of August I guess (LOD2 project ends)

This is the stacktrace:INFO: Loading configuration from: /usr/share/tomcat7/.odcs/config.properties
12:50:02.326 [pool-2-thread-1] ERROR o.s.w.c.ContextLoader - Context initialization failed

Configuration:

This is the central configuration for WEB FRONTEND of IntLib application.

This file contains just a sample configuration and is not used by the

application. Please copy it to WEB-INF/classes/config.properties and customize

it to meet your needs.

The key and element characters #, !, =, and : should be properly escaped

with a preceding backslash to ensure that they are properly loaded.

directory where frontend log should be stored (should not end with / or \ )

frontend.log.directory = /var/log/unifiedviews/frontend

how long should frontend keep log history

frontend.log.keepDays = 7

General settings (should end with "backend/working")

general.workingdir = /usr/share/unifiedviews/backend/working

Backend application configuration

backend.host = 127.0.0.1
backend.port = 5010

Connection configuration setting for relational database

database.sql.driver = com.mysql.jdbc.Driver
database.sql.url = jdbc:mysql://localhost:3306/unifiedviews?characterEncoding=utf8
database.sql.user = dba
database.sql.password = aeF4aeg8

Connection configuration setting for RDF database

use local rdf platform {

database.rdf.platform = localRDF

}

or use remote rdf platform (sesame) {

database.rdf.platform = remoteRDF

database.rdf.url = http://ip6-localhost:8080/openrdf-sesame

database.rdf.user =

database.rdf.password =

}

or user virtuoso platform {

database.rdf.platform = virtuoso

database.rdf.url = jdbc:virtuoso://localhost:1111/charset=UTF-8/log_enable=2

database.rdf.user = dba

database.rdf.password = aeF4aeg8

}

Administrator contact email for sending reports and failure notifications

email.enabled = false
email.admin = admin@example.com

use if email.enabled = true

email.smtp.host = smtp.server.cz

email.smtp.port = 25

email.smtp.ttl = false

email.from = odcs@xrg.mff.cuni.cz

email.authorization = false

use if email.authorization = true

email.username =

email.password =

Configuration of DPU modules

module.path = /var/lib/unifiedviews/target

reserved for developers

module.frontend.expose =

First of all, in stacktrace I can see "DataSourceFactory" (precisely cz.cuni.mff.xrg.odcs.commons.app.dao.db.datasource.DataSourceFactory) class, which, I cannot see here:
https://github.com/UnifiedViews/Core/tree/UV_core_v1.3.0
in the release sources. So, it is very very probable, that you are not instantiating UV_core_v1.3.0 release.
Have you deleted any unifiedviews* files from tomcat/webapps directory before deployin new unifiedviews.war file?

Frontend sample configuration file can be found here https://github.com/UnifiedViews/Core/blob/UV_core_v1.3.0/frontend/src/main/webapp/WEB-INF/config.sample.properties
and backend here
https://github.com/UnifiedViews/Core/blob/UV_core_v1.3.0/backend/conf/config.sample.properties

Config was copied from the repository and only modified for credentials and folders.
Issue is resolved, it was a hickup on my maven build.
A fresh checkout und "mvn clean package" solved it
