HTTP Status 500 - java.lang.NullPointerException

Hi,

I have a problem with last version of confluence (5.6.5) since I upgraded Mac OS to yosemite

actual configuration:   
    -OS: OS X Yosemite
    -mysql(5.5.38) and phpMyAdmin in MAMP
    -tomcat (7.0.50)

To connect confluence with mysql, I use the last version of recommended mysql driver (5.1.34)

When i start confluence, i get this error:

type Exception report

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.50 logs.

 

I searched on the web and the problem came to connection with database.

When I tried to connect to mysql with command and with the driver it's work.

 

My tomcat configuration for confluence is :

<Context path="/confluence" docBase="/Users/admin/Documents/confluence-5.6.5/confluence" debug="0" reloadable="true">
    <Resource name="jdbc/confluence" auth="Container" type="javax.sql.DataSource"
              username="confluence"
              password="**********"
              driverClassName="com.mysql.jdbc.Driver"
              url="jdbc:mysql://localhost:8889/confluence?useUnicode=true&characterEncoding=utf8"
              maxActive="15"
              maxIdle="7"
              defaultTransactionIsolation="READ_COMMITTED"
              validationQuery="Select 1" />
</Context>

Hi Franck,

If you install a Confluence from scracth using the same startup folder, are you able to point to another database and start Confluence without problems? if you can start Confluence correctly, this might indicate a problem with the current configuration. Usually Nullpointeexceptions at the startup indicate that Confluence might not be able to reach the database using the current username and password.

I hope this helps. I'll leave the question open for others to help as well.

Cheers,

Rodrigo
