my site www.sinteag.com,i have tried making changes in siteurl , home url in database not able solve it.site generating own url on every anchor...like if visit site , click on read more buttons or social icons in footer show own site url first designated url, stuck due issue. this text metting requirments lorem ipsum dolor sit amet, consectetur adipisicing elit, sed eiusmod tempor incididunt ut labore et dolore magna aliqua. ut thanks in advance. you have absolute links (which include site domain) without http:// . html requires prefix website names explicitly state domain http:// or whatever applies site. so <a href="http://sinteag.com">lorem ipsum</a> , similar.

if request made html page, how return directly struts.xml without going action? create action has result in struts.xml doesn't have class , i.e. <package name="default" extends="struts-default"> <action name="index"> <result name="mypage">/path/to/page.html</result> </action> you create global result, found action, i.e <global-results> <result name="mypage">/path/to/page.html</result> </global-results> <action name="index"/> you create interceptor returns result while intercepting , action. these essential elements of configuration invoke dispatcher forward requested page.

my asp.net mvc 4 website urls looks "/language/controller/action". html code of link in menu , in footer same. <li><a href="@url.action("websitedevelopment", "service", new { area = "" })">website development</a></li> when site opened in "en-gb" culture link in menu pinting to /en-gb/service/websitedevelopment but link in footer is /hy-am/service/websitedevelopment how possible? how can fix this? you don't specify "language" in url.action, takes default language. asp.net links absolute ones, without specifying language, it's /default-language/controller/action if want language taken current url, need write own url.action function, or extend it.

i new css , sencha touch 2. while working on tutorial on sencha touch 2,i see css file having code /* increase height of list item title , narrative fit */ .x-list .x-list-item { min-height: 10.5em!important; height:7.5em; } /* move disclosure button account list item height increase */ .x-list .x-list-disclosure { position: absolute; bottom: 4.0em; right: 0.10em; } is .x-list .x-list-item css nesting concept , x-list class name? , concept purely css concept or sencha touch concept? it's pure css concept, syntax means .x-list .x-list-item select element class x-list-item nested under element having class x-list the same goes second syntax. if want make more stricter, can use element.class selector select if matches element.class combination, if taken example.. using like div.x-list span.x-list-item { /* select span having class x-list-item nested under div element having class x-list */ }

is there way make code more concise not have many overloaded methods? public void method(string[] args1, string[] args2){} public void method(string[] args1, string args2){} public void method(string args1, string[] args2){} public void method(string args1, string args2){} the number of overloaded methods increases exponentially number of arguments increases. problem, , know there has easier way this. the goal find best way pass number of objects of same type argument without using array single-object input. why? it's simplicity end programmer. maybe if have great number of arguments - besides - can increased in future, it's better wrap them in separate class, i.e. inputparams , pass 1 instance of class method. consider next code: inputparam ip = new inputparam(); ip.setfield1(field1); //... // usage this.method(ip); // declaration public void method(inputparams arg){} p.s. but, other guys mentioned, depends on many conditions , trying achieve.
