Dear professional friend OS: WIN XP-PRO IDE: JDeveloper 9.0.3 DBMS: Oracle9i _______________________ Problem: _______________________ Having a sample application in Jdev including some Servlets and JSPs, I had no problem to be connected to the Oracle9i, but suddenly it is the second day that I've got the following common exception: SQLExceptionjava.sql.SQLException: Io exception: The Network Adapter could not establish the connection - 17002 When trying the following code: -DriverManager.registerDriver(new oracle.jdbc.OracleDriver()); -StringUrl="jdbc racle:thin:@localhost:1521 racle9i"; -conn1=DriverManager.getConnection(url,"scott","tiger"); I have done no changes except for installing OC4J9.0.3 stand alone version. After that I got some messages in Jdev, warning about some conflicts in ports and some automatic new port assignments. Mean while I don't know why when starting the machine for the first time I can log in to the Enterprise Manager, but it can't be done after running the Jdev?(messaging: "ORA-12541 TNS:no listener"), but I can login through SQL+ ? Any hint and advice will be of great help and be appreciated so much. Thanks; Pourang [ December 21, 2002: Message edited by: Pourang Emami ] [ December 21, 2002: Message edited by: Pourang Emami ]
