is it possible to set -D params programaticaly?

Have you tried:

System.setProperty("java.naming.security.credentials", "123qwe");

BTW, if this is your JMS question, then a file jndi.properties in classpath
with the properties you need should be fine (and more flexiable than hardcoding)

Hello!

If I'm right I may set this in the Context like:

    java.util.Properties properties = loadProperties("jmslabb/jndi.properties");
    jndiContext = new InitialContext(properties);

    public static java.util.Properties loadProperties(String fileName)
    {
        try
        {
            java.util.Properties properties = new java.util.Properties();
            properties.load(new FileInputStream(fileName));
            return properties;
        }
        catch(Exception e)
        {
            e.printStackTrace();
            return null;
        }
    }
Where the jndi.propretis looks like:
java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory
java.naming.provider.url=ldap://xxx.xxx.xxx.com:7676/
java.naming.security.principal=admin
java.naming.security.credentials=xxxxxxxx
javax.jms.QueueConnectionFactory

An other way is to have the jndi.properties file in the classpath.
