Proxy user authentication with BC4J

Question

On my webapp i have a connections pool and a MyApplicationModule.
I can obtain a OracleConnection instace by overriding the method prepareSession()
into the application module.
I need to associate the OracleConnection with the ApplicationModule object to execute my queries with the application module and the proxy user.
The application module is created by this code:
appMod = (MyApplicationModule)Configuration.createRootApplicationModule("xx.xxx.MyApplicationModule", "MyApplicationModuleLocalTest1");
The prepareSession ovverride is done by this code:
protected void prepareSession(Session session) {
Statement st = null;
try {
st = getDBTransaction().createPreparedStatement("rollback",0);
OracleConnection oConn = (OracleConnection)st.getConnection();
Properties props = new Properties();
props.put("PROXY_USER_NAME", "USERTEST");
oConn.openProxySession
(OracleConnection.PROXYTYPE_USER_NAME,props);
catch (SQLException s) {
//ignore
finally {
if (st != null) {
try {
st.close();
catch (SQLException s) { }
super.prepareSession(session);
Tanks and sorry for my poor english.

Answer 1

I found the possibility that proxy authentication of both accounts can be enforced:
SQL> alter user appuser grant connect through personaluser AUTHENTICATION REQUIRED;
I guess that this is the motivation for implementing the 2-session proxy connection method in SQL Developer.
