Please tell me your idea about my manner of using proxy user

Question

Hello
Please say to me your idea about my manner of using proxy user , I don't know that my method is right , doesn't it has security weakness ?
Let me to say what I wanna do :
I want my application users authenticated by database , therefore in my database (Oracle database) I create a user for every application user for example if I have 10 application user I create 10 user in the database for them and I grant necessary privileges to them
Now I create a proxy user and grant to my users connect through the proxy user
for example
alter user user1 grant connect through user_proxy with role role1 authentication required;
alter user user2 grant connect through user_proxy with role role1 authentication required;
alter user user10 grant connect through user_proxy with role role1 authentication required;
And now in Weblogic I create a DataSource that connect to the database by that proxy user
My client Application (It's a stand alone application) obtain the DataSource from Weblogic and then get from operator its user name and password and then create a proxy session
in below I've written the application's code
Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7001");
try{
Context context=new InitialContext( env );
ds=(javax.sql.DataSource) context.lookup ("OracleConnection2");
conn=(OracleConnection) ds.getConnection();
java.util.Properties prop = new java.util.Properties();
String username=getUserNameFromOperator();  //Operator enter user1
String password =getPasswordFromOperator(); //Operator enter its password
prop.put(OracleConnection.PROXY_USER_NAME, username);
prop.put(OracleConnection.PROXY_USER_PASSWORD,password);
conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME, prop);
stmt= conn.createStatement();
rs=stmt.executeQuery("select SYS_CONTEXT('USERENV','PROXY_USER') ||'--->' || user from dual");
My anxiety is that this section
String username=getUserNameFromOperator();  //Operator enter user1
String password =getPasswordFromOperator(); //Operator enter its password
prop.put(OracleConnection.PROXY_USER_NAME, username);
prop.put(OracleConnection.PROXY_USER_PASSWORD,password);
operator enter a real database username and password
don't you think it cause security weakness ?
do you have better suggestion for me ?
thank you

Gmail offers POP, which means you can use Mail.app like a regular ISP account. If you need an invite to GMail email me at the address on http://Gnarlodious.com/
Once yiou have a Gmail address you need to enable POP (which includes SMTP). There is a help link on the GMail page that allows you to enable POP and other features.
Once that is turned on, you need to set up the Mail.app for downloading your mail (and uploading). There are excellent instruction pages on Gmail, which I believe someone else gave you.
