Could somebody help be to understand why "java.naming.security.principal" and "java.naming.security.credentials" keys were put into JndiTemplate weren't applied while lookup.

Problem details:
When I call ejb via spring proxy that was injected by jndi template it doesn't send userPrincipal and Credentials to ejb, and if I сheck value of javax.ejb.SessionContext.getCallerPrincipal() it will be set to "anonymous" on Ejb.

Application server - WebLogic 10.3.

My Spring's xml file:
Code:
<beans default-lazy-init="true">

    <bean id="jndiTemplate"
          class="org.springframework.jndi.JndiTemplate">
        <property name="environment">
            <props>
                <prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
                <prop key="java.naming.provider.url">t3://localhost:7001</prop>
                <prop key="java.naming.security.principal">test-user</prop>
                <prop key="java.naming.security.credentials">g0dGres9</prop>
            </props>
        </property>
    </bean>

    <bean id="testBean"
          class="org.springframework.ejb.access.SimpleRemoteStatelessSessionProxyFactoryBean">
        <property name="jndiName" value="app.Bean1"/>
        <property name="businessInterface" value="test.Bean1"/>
        <property name="jndiTemplate" ref="jndiTemplate"/>
    </bean>
</beans>
My Test java class file is:
Code:
import test.Bean1;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;

import java.util.List;

public class Test {
    private static XmlBeanFactory beanFactory;

    public static void main(String... params) throws Exception {
        Bean1 bean = (Bean1) getBeanFactory().getBean("testBean");
        bean.callSomeMethod();
    }

    public static BeanFactory getBeanFactory() {
        if (beanFactory == null) {
            final Resource resource = new FileSystemResource("spring.xml");
            beanFactory = new XmlBeanFactory(resource);
            beanFactory.preInstantiateSingletons();
        }

        return beanFactory;
    }
}
