cannot start jasperserver 2.1

[mkjei]

Hi,

I wanted to test out the jasperserver upgrade from 2.1 to 3.0, and I copied jasperserver webapps directory to another directory (testjasper), and then changed the context.xml so that it points to this other mysql instance from another machine (which I replicated the whole jasperserver database from the orginal one)

 

but when i started it, it failed, and from the webapps log, i saw the following error:

ERROR JDBCExceptionReporter,TP-Processor2:78 - Cannot create JDBC driver of class '' for connect URL 'null'
WARN SettingsFactory,TP-Processor2:109 - Could not obtain connection metadata
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'

my original jasperserver is still running fine on the same machine, and off of the same tomcat instance, so I m not sure what is going on ....

 

thanks

I don't think you can do that, because the database and much of the code have changed. There are some scripts included to upgrade from 2.1 to 3.1, and you could run them in a test server so you don't mess with your production data.

thats exactly what i wanted to ask .... i wanted to create a test server based on my current data on jasperserver ... 

on the same machine, i duplicated the jasperserver webapp directory into a new name, and then copied the entire jasperserver database to another machine, modified this new duplicated jasperserver's context.xml so that it points to this new database location ... but then I m getting this null errors when I try to start it up ...

Your mysql settings might be different on the test machine.  I setup my test environment by installing jasperserver on the test server, stopping mysql and jasperserver, and then copying my production files on top of the ones I just installed on test.  Not sure if that's the way to go, but it worked for me. :)

Can you post the whole error message here?
