Hi, all:
I try to use DatabaseMetaData to get all tables and views from a
Oracle database. But exception is thrown at the red line. You can see that I
look up a remote DataSource and get connection from the data source. But if
I use *DriverManager.getConnection(url, user, pwd)* way to get connection.
This issue does not exist. I can get all the tables and views successfully…
Any help from you will be much appreciated!
*public* *class* Test {
*public* *static* *void* main(String[] args) *throws* Exception {
Properties props = *new* Properties();
props.put(Context.*PROVIDER_URL*, "jnp://10.111.3.161:1099");
props.put(Context.*INITIAL_CONTEXT_FACTORY*,
"org.jnp.interfaces.NamingContextFactory");
Context ctx = *new* InitialContext(props);
DataSource ds = (DataSource)ctx.lookup("OracleDS");
Connection conn = ds.getConnection();
DatabaseMetaData dbmd = conn.getMetaData();
ResultSet *rs* = dbmd.getTables(*null*, "%", "%", *new* String[] {
"TABLE", "VIEW" });
}
}
Exception:
Exception in thread "main" *java.lang.ClassCastException*: $Proxy3
at $Proxy2.getTables(Unknown Source)
at Test.main(*Test.java:62*)
