no security manager: RMI class loader disabled

tdzierza Nov 21, 2014 2:20 PM

I have EAR with following structure:

application.xml

backend.jar

commons.jar

jboss-service.xml

log4j.jar

MANIFEST.MF

mybatis-3.2.8.jar

permissions.xml

Inside backend.jar simple mbean to test operation connected with user.

public class UserService implements UserServiceMBean {

public void printResults()

{

SqlSessionFactory sqlSessionFactory = ConnectionFactory.getSession();

SqlSession session = sqlSessionFactory.openSession();

try {

UserMapper mapper = session.getMapper(UserMapper.class);

mapper.selectByPrimaryKey(1); // throws exception

} finally {

session.close();

}

System.out.println(message);

}

// The lifecycle

public void start() throws Exception

{

System.out.println(">>>>Starting with message=" + message);

}

public void stop() throws Exception

{

System.out.println(">>>>Stopping with message=" + message);

}

How I run tests:

jconsole -debug

firstly I get Exception:

java.lang.SecurityException: Expecting a javax.rmi.ssl.SslRMIClientSocketFactory RMI client socket factory in stub!

but if I understand well it is depend with unsecure transmission, and I'am working only inside localhost so it shouldn't be reason of my next exception (bolded in code)

java.rmi.UnmarshalException: Error unmarshaling return; nested exception is:

java.lang.ClassNotFoundException: org.apache.ibatis.binding.BindingException (no security manager: RMI class loader disabled)

In very beginnig i tried to use JNDI to implementation of DataSource for MyBatis, but with similar result - RMI class loader disabled. So i switched to xml configuration for MyBatis.

What I did to resolve my problem:

added permissions.xml

<permissions xmlns="http://xmlns.jcp.org/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/permissions_7.xsd"

version="7">

<classname>java.security.AllPermission</classname>

</permission>

</permissions>

without positive result

This is case with JNDI to implementation of DataSource

public class UserService implements UserServiceMBean {

       public void printResults()
       {
          JndiDataSourceFactory JndiDataSource = new JndiDataSourceFactory();

         Properties properties = new Properties();
         Thread currentThread = Thread.currentThread();
         ClassLoader contextClassLoader = currentThread.getContextClassLoader();
         InputStream propertiesStream = contextClassLoader.getResourceAsStream("app.properties");
         if (propertiesStream != null) {
           try {
            properties.load(propertiesStream);
            propertiesStream.close();
       } catch (IOException e) {
            e.printStackTrace();
       }

    } else {
         System.out.println("Properties file not found!");
         return;
    }

         JndiDataSource.setProperties(properties); // this line

       }
...

public class JndiDataSourceFactory implements DataSourceFactory {
...
@Override
public void setProperties(Properties properties) {
try {
       InitialContext initCtx = null;
       Hashtable env = getEnvProperties(properties);
       if (env == null) {
         initCtx = new InitialContext();
       } else {
         initCtx = new InitialContext(env);
       }

       if (properties.containsKey(INITIAL_CONTEXT)
           && properties.containsKey(DATA_SOURCE)) {
       Context ctx = (Context) initCtx.lookup(properties.getProperty(INITIAL_CONTEXT));
       dataSource = (DataSource) ctx.lookup(properties.getProperty(DATA_SOURCE));
       } else if (properties.containsKey(DATA_SOURCE)) {
            dataSource = (DataSource) initCtx.lookup(properties.getProperty(DATA_SOURCE)); // here is exception
       }
...

     } catch (NamingException e) {
       throw new DataSourceException("There was an error configuring JndiDataSourceTransactionPool. Cause: " + e, e);
     }
}

...

AND EXCEPTION:

Caused by: java.lang.ClassNotFoundException: org.apache.ibatis.datasource.DataSourceException (no security manager: RMI class loader disabled)

My mybatis-config.xml

<configuration>
    
    <environments default="development">
        <environment id="development">
            <transactionManager type="MANAGED">
     <property name="closeConnection" value="false"/>
</transactionManager>
            <dataSource type="JNDI">
                <property name="data_source" value="java:jboss/datasources/MyDBName"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <mapper resource="UserMapper.xml" />
    </mappers>
</configuration>

Similar exception no security manager: RMI class loader disabled) , no matter what i will try to do it's failed, connected with security i guess

It could be possible that jconsole is reason ? I think that something is wrong with my wildfly configuration ... maybe something with my mbean service ...
