perfSONAR User Q&A and Other Discussion

[<>]

Greetings,

 

I just deployed the perfSONAR UI server on the CentOS VM (this VM has actually the full toolkit installed) and I’m unable to make the UI work.

In the tomcat6 logs I see the following errors:

 

Aug 05, 2015 3:22:34 PM org.apache.catalina.core.StandardContext listenerStart

SEVERE: Exception sending context initialized event to listener instance of class org.perfsonar.ui.listener.PerfsonarInitListener

<openjpa-2.4.0-r422266:1674604 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: There were errors initializing your configuration: <openjpa-2.4.0-r422266:1674604 fatal user error> org.apache.openjpa.util.UserException: A connection could not be obtained for driver class "org.apache.derby.jdbc.EmbeddedDriver" and URL "jdbc:derby:/var/lib/perfsonar-ui/database;create=true".  You may have specified an invalid URL.

        at org.apache.openjpa.jdbc.schema.DataSourceFactory.newConnectException(DataSourceFactory.java:254)

        at org.apache.openjpa.jdbc.schema.DataSourceFactory.installDBDictionary(DataSourceFactory.java:240)

        at org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.getConnectionFactory(JDBCConfigurationImpl.java:733)

 

Looks that this is the error assiciated with the Derby Java classes.

I see that there’s a Derby class in the application directory:

 

/usr/share/perfsonar-ui-web/perfsonar-ui/WEB-INF/lib/derby-10.11.1.1.jar

 

I’m not very well with the tomcat/java, sorry so absolutely out of ideas what to do next…

 

Any help will be VERY appreciated!
