Frank2Example4 does not start - maybe ROOT.xml is invalid #30

When I started Frank2Example4, the following exception appeared in the Tomcat window:

I checked the ROOT.xml file C:\Users\martijn\frank-runner\build\apache-tomcat-9.0.50\conf\Catalina\localhost\ROOT.xml. It reads:

<Context docBase="./examples/Frank2Example4/src/main/webapp">
    <Resource
        name="jdbc/frank2example4"
        type="org.h2.jdbcx.JdbcDataSource"
        factory="org.apache.naming.factory.BeanFactory"
        URL="jdbc:h2:C:\Users\martijn\frank-runner/build/h2/frank2example4"
    />
</Context>

I see that the path in the URL mixes up Windows and Linux path separators. I tried to make all path separators Windows-style and then start Tomcat using Catalina start. I got the same exception.

This is on the master brach. No changes here to refer to the Frank!Doc.

On my machine it's working. I have the same difference in separators. Let's look into it together when you have time

Frank2Example4 as it is now is not so useful anymore. It is present as test input for the Frank!Flow, but Frank2Example- applications should be showcases of the Frank!Runner. This issue will be updated to demonstrate Frank configurations as Maven projects. Debugging is not relevant until this update has been done.
