re documentation
http://docs.oracle.com/javase/6/docs/api/java/sql/ResultSetMetaData.html

re example

Server: 9.0.4 Driver: PostgreSQL Native Driver: PostgreSQL 9.1 JDBC3
(build 901)

ResultSet rs = meta.getTables(null, null, null, null);
ResultSetMetaData rsmd = rs.getMetaData();
System.out.println(rsmd.getColumnCount());

This will print the value of 5 not 10.

Change the code to
for (int i = 1; i <= rsmd.getColumnCount(); i++) {
 System.out.println(rsmd.getColumnName(i));
}

http://docs.oracle.com/javase/6/docs/api/java/sql/DatabaseMetaData.html#getTables(java.lang.String,
java.lang.String, java.lang.String, java.lang.String[])
returns names as follows was expecting upper case names similar to
rs.getString("TABLE_NAME")
table_cat
table_schem
table_name
table_type
