below java file code:-

    package util;     import java.sql.connection;     import java.sql.drivermanager;     import java.sql.preparedstatement;     import java.sql.resultset;      public class javasqlconnection{          public static void main(string[] args) throws exception {             string connectionurl="jdbc:sqlserver://10.6.1.67";             string port="1433";             string databasename="microsoft";             string user="selenium";             string password="password123";             class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver").newinstance();             connection conn = drivermanager.getconnection(connectionurl+":"+port+";databasename="+databasename+";user="+user+";password="+password);              string sql = "select name, address, url school schoolid=?";             preparedstatement stmt = conn.preparestatement(sql);             resultset rs = null;             stmt.setint(1, 875632);             rs = stmt.executequery();             while (rs.next()){                 system.out.println(rs.getstring("url"));             }             stmt.close();             conn.close();         }     }

this how have created ant build.xml:(i execute ant target run)

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
