Array as output in Webservice

Hi ,

I have written a method and the return type of the method if array . Somehow I am not able to see any output on webserivce navigator. But when I run the same program as standalone application it works. Here is the code -

	public String[] postGRData() {

		String[] AUFNR = new String[20];
		
		
		for (int i = 0; i < AUFNR.length; i++) {
			AUFNR<i> = new String();
		}
			
		try {
			Connection conn;
			InitialContext ctx = new InitialContext();
			DataSource dataSource =
				(DataSource) ctx.lookup(readPropertyFiles());
			conn = dataSource.getConnection();

			ResultSet rs;
			PreparedStatement stmt =
				conn.prepareStatement(
					"select * from zae_prod_grtable where status = ?");
			stmt.setInt(1, 1);
			rs = stmt.executeQuery();

			int i = 0;
			while (rs.next()) {
		        AUFNR<i> = rs.getString("AUFNR");
				i = i + 1;
			}
			stmt.close();
			conn.close();		
			return AUFNR;
		} catch (Exception ex) {

		}

		return AUFNR;
	}
