my java code is:

 public connection getconnection() {         string connectionurl = "jdbc:sqlserver://localhost:49184;databasename=alarm;user=sa;password=controls@#$%";         try {       class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver");       con = drivermanager.getconnection(connectionurl);     } catch (exception e) {       system.out.println(" \nexception in getconnection() " + e);     }     return con;     }     public void closeconnection(statement stmt, resultset rs, connection con) {     try {       if (stmt != null) {         stmt.close();       }       if (rs != null) {         rs.close();       }       if (con != null) {         con.close();       }       } catch (exception e) {       system.out.println("\nexception in closeconnection( statement stmt, resultset rs, connection con)  " + e);     }     }          public int get_count1()     {       {             try {         con = getconnection();           stmt = con.createstatement();           string sql = " select system_name, count(distinct arrival_time) c i2alarmlog ack_status = 0 , direction='came' , arrival_time between '2014-01-22 17:56:41.000' , '2014-01-24 17:56:41.000' , system_name in('i2-tciu database','i2-vcs logging','indus1 vacuum','indus2 tciu','indus2 vacuum','septum_sip2','tl3 vacuum') group system_name union select 'totalsum' totalsum,sum(s.c) totalvalue (select system_name, count(distinct arrival_time) c i2alarmlog ack_status = 0 , direction='came' , arrival_time between '2014-01-22 17:56:41.000' , '2014-01-24 17:56:41.000' , system_name in('i2-tciu database','i2-vcs logging','indus1 vacuum','indus2 tciu','indus2 vacuum','septum_sip2','tl3 vacuum') group system_name ) s";             stmt.executequery(sql);         rs = stmt.getresultset();               while (rs.next()) {           t1 = (rs.getint(2));             }         } catch (exception e) {         system.out.println("\nexception " + e);         } {         closeconnection(stmt, rs, con);       }       }           system.out.println(t1);       return t1;     }

how resolve it. have used jsp display.i have used chartdirector displaying charts as:-

<% @page import = "chartdirector.*" %>    <%    // data line chart      double[] data1 = ab.total();    // labels line chart  string[] labels = {    "vacuum", "rss", "mps", "rf", "blfe", "orbit", "lcw", "tcs", "interlock", "bds", "msis", "microton", "power conditioner", "database"  };    xychart c = new xychart(1000, 650);  c.setplotarea(90, 60, 750, 430);    c.xaxis().setlabels(labels);  c.xaxis().settitle("system_name", "arial bold", 12);  c.xaxis().setlabelstyle("arial bold", 10).setfontangle(45);    c.addbarlayer3(data1).setbordercolor(chart.transparent, chart.softlighting(chart.left));    barlayer layer = c.addbarlayer2(chart.stack, 10);  layer.setaggregatelabelstyle();  layer.adddataset(data1, 10, "arial bold italic");  layer.setbordercolor(chart.transparent, chart.softlighting(chart.top));    c.xaxis().setcolors(chart.transparent);  c.yaxis().setcolors(chart.transparent);      c.yaxis().settitle("alarm_count", "arial bold", 12);    c.yaxis().setlabelstyle("arial bold", 10);  c.yaxis().setlinearscale(0.0, ab.max_count());  c.yaxis().setlabelstep(2);  c.yaxis().setmargin(7);  c.xaxis().setwidth(2);  c.yaxis().setwidth(2);      try {    // stream chart browser , terminate    out.clear();    if (webchartviewer.streamchart(response, c.makechart2(chart.png)))      return;  } catch (illegalstateexception e) {    // old servers may not support streaming. forced redirect    // browser use traditional method.    response.sendredirect(response.encoderedirecturl("getchart.jsp?" +      c.makesession(request, "chart")));    return;  }      %>

moreover,the chart updated randomly.
