Getting an exception ORA-00942: table or view does not exist - when inserting into an existing table

I am getting below exception, when trying to insert a batch of rows to an existing table

ORA-00942: table or view does not exist

I can confirm that the table exists in db and I can insert data to that table using oracle sql developer. But when I try to insert rows using preparedstatement in java, its throwing table does not exist error.

Please find the stack trace of error below

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

Can anyone suggest the reasons for this error ?

Update : Issue solved

There was no problem with my database connection properties or with my table or view name. The solution to the problem was very strange. One of the columns that I was trying insert was of Clob type. As I had a lot of trouble handling clob data in oracle db before, gave a try by replacing the clob setter with a temporary string setter and the same code executed with out any problems and all the rows were correctly inserted!!!.

ie. peparedstatement.setClob(columnIndex, clob)

was replaced with

peparedstatement.setString(columnIndex, "String")

Why an error table or view does exist error was throws for error in inserting clob data. Could anyone of you please explain ?

Thanks a lot for your answers and comments.
