orientdb server v2.0.10 , trying come query following scenario. i have 2 hierarchies: a->b->c , d->e->f number of nodes in hierarchy can change. node in 1st hierarchy can connected other hierarchy using relation 'assigned'. want parent node of 2nd hierarchy if there incoming edge of node in 2nd hierarchy 1st. for example, have car-child->engine-child->piston , country-child->state-child->city , relationship made_in relates car or engine or piston either country or state or city if there relation either of country or state or city, country should returned. example, engine1-made_in->berlin, return germany. sorry such toyish example. hope clear. thanks. you should consider reading chapter "traversing" - should missing link answer question. can find here: http://orientdb.com/docs/last/sql-traverse.html basically, if think of graph family tree, want achieve 3 things: find children, grand-children, grand-grand-children (an...

i trying write code div telling user how far has scrolled down page. here code: $(document).scroll(function(){ var fullheight = $(this).height(); var currentheight = $(this).scrolltop(); var percentageofpage = currentheight/fullheight; percentageofpage = percentageofpage.tofixed(2); var t = $("#t"); t.html("you " + percentageofpage + " down page." ); }); fiddle code works how should: writes out percentage how far user has scrolled. stops @ .67 or .69. why that? want go way 1. also, how can display percentage, 60%, instead of decimal, .6? here page is. addition : how can make @ when user reaches bottom of page, message becomes: "you have reached bottom of page", instead of percentage? $(document).on('scroll.percentage', function() { var scrollpercent = math.round(100 * $(window).scrolltop() / ($(document).height() - $(window).height())); // if user has reached bottom of page // unbind scroll liste...

tomcat used running java servlets, has webserver functionality built in, can run independently. however, see several articles on how integrate apache webserver tomcat? what's purpose of doing this? improve performance? i using tomcat serving webservices. tomcat fine servlet container, there lot of things apache httpd can better (easier and/or faster). for example apache can handle security, ssl, provide load balancing, url rewriting etc. you can split content: can have apache httpd serve static content images, static html, js etc. , leave dynamic content (like servlets, jsp etc.) tomcat. has advantage failure in tomcat not render whole web site unusable / unavailable (just servlets/jsp pages). you can separate 2 , increase security: can run apache httpd on 1 server (which reachable on internet) , direct server running tomcat, invisible outside.
