Question

I am trying to go through a tutorial on GroovySQL. The database I need to connect to is an Oracle database. So I downloaded ojdbc6.jar and put it in ~/.groovy/lib/. If I put the following script in a .groovy file, I can do groovy testScript.groovy and it will succeed:

import oracle.jdbc.driver.OracleDriver
println(OracleDriver.getCompileTime())

When I try to do the same thing via groovysh, I get the following error:

How can I use the Oracle JDBC driver from within the Groovy shell?

Answer 1

Run the shell without a SecurityManager that doesn’t allow to register new MBeans (that’s what the exception says).

Look for -Djava.security.manager in the startup script of the Groovy shell or for System.setSecurityManager() in the source code.

Note that you’re opening your system to all kinds of attacks if you do that.

OTOH, configuring a SecurityManager using the standard tools is so complicated that I’m pretty sure no one ever got it right for any non-trivial example, so the question is whether the pains from installing one outweigh the gain in security.
