"ORA-00911: invalid character" coming when calling oracle procedure from java

I have a procedure which is working fine when i run on sql developer.

    create or replace
    PROCEDURE test(Order in varchar,Id in number ,status out varchar) As
    logic
    dbms_output.put_line(status);
    end;

However when i am calling this procedure from java it showing error ORA-00911: invalid character.My java code is

    String proc3StoredProcedure=null;
    try {
        proc3StoredProcedure = "{ test(?,?,?) }";

            } catch (Exception e) {
        // TODO Auto-generated catch block
         System.out.println("exception");

        e.printStackTrace();
    }
    CallableStatement cs = conn.prepareCall(proc3StoredProcedure);
    cs.setEscapeProcessing(false);


    cs.setString(1,"17");
    cs.setInt(2,37);

    cs.registerOutParameter(3, java.sql.Types.VARCHAR);
    cs.execute();

    String param4 = cs.getString(2);




    System.out.println("param4=" + param4);


    conn.close();
}

What I am doing wrong in java code.I have tried many things but its not wroking.Can anyone help me?

Change the string assigned to proc3StoredProcedure to { call test(?,?,?) }.

Docs for JDBC SQL escape syntax here. (The syntax for procedure calls is at the very bottom of the linked page).
