Dynamic Visibility Function in TCA

Question

Hi,
I have a requirement where I need to create couple of buttons using Extensions (Extensible Attributes) in Customers Online (similar to User Defined Attributes in Oracle Adavanced Product Catalog) . The problem I have is I need to make these buttons dynamically visible. Now we can make these buttons dynamically visible only by using User Defined Java Functions (as we can't use User Defined PL/Sql functions here!).
I have found a sample code of this user defined java function from the knowledge base which is very simple and is given below. My problem is how can i make call to database pl/sql packages from within this java function (i.e. how to get the page context in my standalone java class?).
I would really appreciate any help/suggestions on this.
Java Code for user defined java function:
public class XX_PARTY_SITE_Function
public static oracle.apps.ego.common.EgoBoolean getVisible (StringBuffer theInput)
try {
if ("N".equals(theInput.toString())) {
return (new oracle.apps.ego.common.EgoBoolean( new Boolean("True"))) ;
} else {
return (new oracle.apps.ego.common.EgoBoolean( new Boolean("False"))) ;
catch ( NullPointerException e ) {
return (new oracle.apps.ego.common.EgoBoolean( new Boolean("True"))) ;
Thanks,
Kamal

hi
use this example in your code
import java.sql.CallableStatement;
import java.sql.SQLException;
import java.sql.Types;
OADBTransaction txn = getDBTransaction();
CallableStatement cs =
txn.createCallableStatement("begin dbms_application_info.set_module(:1, :2);
end;");
try
cs.setString(1, module);
cs.setString(2, action);
cs.execute();
cs.close();
catch (SQLException sqle)
try { cs.close } catch (Exception(e) {}
throw OAException.wrapperException(sqle);
This example illustrates an OUT parameter:
import java.sql.CallableStatement;
import java.sql.SQLException;
import java.sql.Types;
import oracle.jdbc.driver.OracleCallableStatement;
DBTransaction txn = getDBTransaction();
String sql = "BEGIN :1 := FND_MESSAGE.GET; END;";
CallableStatement cs = txn.createCallableStatement(sql, 1);
String messageBuffer = "";
try
665
((OracleCallableStatement)cs.registerOutParameter(1, Types.VARCHAR, 0, 2000);
cs.execute();
messageBuffer = cs.getString(1);
cs.close();
catch (SQLException sqle)
try { cs.close } catch (Exception(e) {}
throw OAException.wrapperException(sqle);
