HTTP 500 - Cannot create JDBC driver of class '' for connect URL 'null'

Question

I have been searching to fix that problem for 3 days reading forums... Then I decided to ask for some help. Nedless to say that your help would be highly appreciated :-)

Answer 1

I've eventually found out the solution and I'll share it with those who are encountering the same problem.

Create the META-INF folder under src/main/webapp as WEB-INF sibling Move the Tomcat-config/context.xml file to the META-INF folder. You'll see in the pom.xml that this file is not going to be part of the WAR file.

META-INF/context.xml

    
    WEB-INF/web.xml

 

Adapt the pom.xml

            org.apache.tomcat.maven
            tomcat7-maven-plugin
            2.2
            
                http://127.0.0.1:8080/manager/text
                TomcatServer 
                /${project.build.finalName}
                8080
                UTF-8
                ${project.build.finalName}
                ${project.basedir}/src/main/webapp/META-INF/context.xml 
            
            
                
                    mysql
                    mysql-connector-java 
                    5.1.27
                
            
        

MAVEN_HOME/conf/settings.xml The id is referenced in the pom.xml. The username and the password are declared in the tomcat-users.xml

    TomcatServer
    xxxxx
    xxxxxxxxx

Eclipse / Run - Run configurations ...

• create new launch configuration
• Base direrctory ${workspace_loc:/your project name}

• Goals clean tomcat7:run

• Apply

• Run

Next time you can click on the arrow near the Run As... button in the ToolBar and select the configuration you want to run. The Stop and Relaunch buttons are very useful.
