hi new dynamicjasper, created sub report when set border using setborder property subreport raise exception java.lang.reflect.invocationtargetexception

this subreport code

public dynamicreport buildreport() throws exception {          fastreportbuilder frb = new fastreportbuilder();         frb.settitle("project documentation")            .setmargins(5, 5, 20, 20);          frb.addcolumn("","project_id", string.class.getname(), 30)         .addcolumn("","product_name",string.class.getname(),30)          .setquery("select * project_master project_id=$p{project_id}", djconstants.query_language_sql);          size = table_name.size();          delete_table = table_name;          system.out.println("size = = = "+size);           frb.addgroups(2);          for(int s=0;s<table_name.size();s++){             system.out.println(" s "+s+" = "+table_name.get(s).tostring()+" s_n "+seciton_name.get(s).tostring()+" tab_type "+table_type.get(s).tostring());         frb.addsubreportingroupheader(2, subreport(table_name.get(s).tostring(),seciton_name.get(s).tostring(),table_type.get(s).tostring()),getlayoutmanager  (),"getdatasourcesubreport"+s,djconstants.subreport_parameter_map_origin_parameter,djconstants.data_source_type_jrdatasource);        params.put("getdatasourcesubreport"+s, getdatasourcesubreport(table_name.get(s).tostring()));              }          frb.setprintbackgroundonoddrows(true);          frb.setusefullpagewidth(true);         params.put("project_id","pjt/0001");          return dr;     }  public dynamicreport subreport(string tab_name,string tit_name,string tab_type)throws exception{ **style tbl_border = new stryle();        tbl_border.setborder(border.thin());** //***error occured in line***        fastreportbuilder drb1 = new fastreportbuilder();        if(tab_type.equals("textarea")){            int max_width = 0;                     statement st5 = connection.createstatement();             resultset rs5 = st5.executequery("select column_name information_schema.columns table_name='"+tab_name+"'");             while(rs5.next()){                                 system.out.println("inside while textarea");                     if(max_width>=1){                       drb1.addcolumn("",rs5.getstring(1).tostring(),string.class.getname(),25);                       }                     max_width++;             }              drb1.setusefullpagewidth(true);         }        if(tab_type.equals("table")){              int max_width =0;                     statement st5 = connection.createstatement();                 resultset rs5 = st5.executequery("select column_name information_schema.columns table_name='"+tab_name+"'");                 while(rs5.next()){                     system.out.println("inside while");                        **drb1.addcolumn(rs5.getstring(1).tostring(),rs5.getstring(1).tostring(),string.class.getname(),25)addstyle(tbl_border);**                          max_width++;                 }            if(max_width>2){                 drb1.setusefullpagewidth(true);             }        }  //           for(int sg=0;sg<header.size();sg++){ //             drb1.addcolumn(header.get(sg).tostring(),header.get(sg).tostring(),string.class.getname(),25); //           }               drb1.setsubtitle(tit_name);              drb1.settitle("");                   dynamicreport dr1 =   drb1.build();               return dr1;    }

in above code set 1 condition if table need exact border table, how can achieve it

its conflict using dyanamicjasper3.0.6 because not containing border class correctly, when u used dynamicjasper 4.0.3 , 3.0.6 in same project consider 3.0.6 not 4.0.3. remove 3.0.6 , use 4.0.3 surely working.

Why does Ruby on Rails generate add a blank line to the end of a file? -
