      We'll appreciate more detail like the version you're using, OS, Web Server, the full error output, etc...

      But based on the piece you showed it seems like the commonsdbcp.jar is missing.

          Hi Ssara, the problems really seems to be related to the data base connection pool. If the commonsdbcp.jar didn't works, let's try something else:

          - What is the version of your MySQL data base?
          - Did you copy the file mysql-connector-java-3.1.7-bin.jar to folder common/lib/ of Tomcat
          - Did you have any other application working with your Tomcat?

          thanks!

              Hi ssara, I will try to reproduce your problem here in my invironment. For a while, there is a work-around that is to use Tomcat 5.0.28. The Plandora installation procedures was wrote based to version 5.0.28 and for Tomcat 5.5, I think we must to create a context.xml file and change some configurations of connection pooling... (and the current Plandora installation procedure don`t have this).
              I will study about your problem and I will post the solution here as soon as possible. (I hope ;-) )

              merci!

                Can you send me the current context.xml file? I have applications (Xinco DMS also on sourceforge) with 2 versions of context file, before tomcat 5.5 and after. So I might help on creating the 5.5+ version.

        Hi everybody,

        Mr. Gonzaga has solved his problem. He made contact with the Plandora support e-mail and report the following:

        Firstly, he saw an error message that appeared in Plandora login form with a message: "Cannot create JDBC driver of class '' for connect URL 'null'"

        Normally, this kind of message error occurs when the JNI settings of Tomcat it's not working appropriately. Plandora, uses the JNI facilities through Tomcat DataSource to access the data base.

        There is a very useful link that explain the typical root causes for this problem:
        http://geeklondon.com/blog/view/tipnulljdbc

        In addition of this site, the Plandora team recomends to check :
        - If the file mysql-connector-java-3.1.7-bin.jar is placed into the folder common/lib/ of Tomcat
        - to keep in mind that there are different configurations of data sources between Tomcat 5.0.x and 5.5.x. Read the Plandora installation process for more information: http://plandora.sourceforge.net/project.htm

        In the case of  Mr.Gonzaga, all this things was done appropriately but the problem was persisting. Then, he re-installed the Tomcat and repeat all this steps. Now it working.

    This seems to be a common issue with RPM based installs.  I seemingly fixed mine by simply adding:

    JAVA_OPTS="-Djavax.sql.DataSource.Factory=org.apache.commons.dbcp.BasicDataSourceFactory"

    to the end of the /etc/tomcat5/tomcat5.conf file and restarting tomcat5, service tomcat5 restart.

    Thanks
