Invalid Geometry Error - while entering data into postgis

[Varshal Davda]

I want to enter data into postgis using java.

But, I am getting error like - 

org.postgresql.util.PSQLException: ERROR: parse error - invalid geometry

  Hint: "{"" <-- parse error at position 2 within geometry

My code is like this : 

Class.forName("org.postgresql.Driver");

conn=DriverManager.getConnection(url,username, password);

sql=conn.createStatement();

result1 = "insert into test(feature) values(ST_GeomFromText('"+geom+")'))";

sql.executeUpdate(result1);

what's wrong?

Thanks
