perfSONAR User Q&A and Other Discussion

[<>]

Ivan,

 

I was able to fix this issue by copying the Derby JAR into the tomcat6 LIB directory.

All this is somewhat strange because I expected that all libs in the app subtree will be accessible by design.

Hi Eugene,

 

Please note that perfSONAR UI service is a separate central UI implementation and has no dependency on the perfSONAR toolkit.

Please share the info about the version of Tomact you are using and the memory size. Did you follow these instructions on the deployment http://docs.perfsonar.net/install_psui.html ?

 

Please note your inquiry has been forwarded to the responsible developer.

 

Best regards,

Ivan

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!
