java.sql.SQLException: ORA-00942: table or view does not exist

when i was trying to read data from Oracle database using the following code i was getting exception

PreparedStatement pst=con.prepareStatement("SELECT * FROM TBLUSER");
pst.executeQuery();

But this table is actually exist in my database when i use this command directly in the command prompt its working fine.And also for one table among the tables in database this code is working fine ,but for other table names its not working properly.So someone please explain why this is happening.

I had this error when using persist() in Hibernate and the solution was to execute:

grant all on <schema>.<table> to <user>;
grant all on <schema>.<sequence> to <user>;

Check if you are using the correcte informations :

String url = "jdbc:mysql://localhost:3306/YOUR_SCHEMA";
Driver driver = com.mysql.jdbc.Driver();
String userName = "user";
String password = "pass";

Check each of the following:

1) the spelling of the table or view name.
2) that a view is not specified where a table is required.
3) that an existing table or view name exists.

Contact the database administrator if the table needs to be created or if user or application privileges are required to access the table.
