CUBA Platform. Developer's Manual
4.2.5.2. The Platform JMX Beans

RootPath – absolute path to the configuration directory of the Middleware block, in which this bean was started.

runGroovyScript() – executes a Groovy script in the Middleware context and returns the result. The following variables should be passed to the script:

The result type should be of the String type, for it to be displayed in the JMX interface. Otherwise, the method is similar to the Scripting.runGroovyScript() method.

The example script for creating a set of test users is shown below:

import com.haulmont.cuba.core.*
import com.haulmont.cuba.core.global.*
import com.haulmont.cuba.security.entity.*

PasswordEncryption passwordEncryption = AppBeans.get(PasswordEncryption.class)

Transaction tx = persistence.createTransaction()
try {
    EntityManager em = persistence.getEntityManager()
    Group group = em.getReference(Group.class, UUID.fromString('0fa2b1a5-1d68-4d69-9fbd-dff348347f93'))
    for (i in (1..250)) {
        User user = new User()
        user.setGroup(group)
        user.setLogin("user_${i.toString().padLeft(3, '0')}")
        user.setName(user.login)
        user.setPassword(passwordEncryption.getPasswordHash(user.id, '1'));
        em.persist(user)
    }
    tx.commit()
} finally {
    tx.end()
