i have multi module project. each module built .jar file takes name corresponding ${project.artifactid} . 1 module built .war file. , here run @ issues. web-inf folder contains lib folder contains result .jars other modules. , these jars have name like: project.artifactid+project.version.jar , when need project.artifactid.jar . i tried configure maven-war-plugin , maven-jar-plugin, result still same. here pom.xml files build results: jar module <groupid>com.mymodule.mysubmodule</groupid> <artifactid>sub-module</artifactid> <version>1.1-snapshot</version> <build> <finalname>${project.artifactid}</finalname> ... result : sub-module.jar war module <groupid>com.mymodule.warmodule</groupid> <artifactid>war-module</artifactid> <version>1.1-snapshot</version> <packaging>war</packaging> <dependency> <groupid>com.mymodule.mysubmodule</groupid> ...

i have wpf application contains datagrid. bound list object "orders" shown below. public class orderblock { public settings setting; public list<order> orders; } public class order { public int amount; public string orderid; public string orderiddup; public string name; public string namedup; public bool dupids; // , string, int fields } for reasons out of control possible there can more 1 orderid, hence orderiddup property. datagrid default shows orderid , not orderiddup. what user able click on cell id , window load show them other id 2 names , let them choose id should used. i have been reading wpf datagrid doesn’t support functionality of double clicking on cell. bit lost how should start going issue. other issue can see trying (being operative word) use mvvm design how kind of event exposed view model? also best way go showing such information. any great, thanks, m instead of double-clicking on cell may double-click on gri...

i testing css on forms , bumped on this: http://jsfiddle.net/gespinha/z4a4g/1/ as try make form inputs round-cornered, assume whole input round object. border-radius:50%; any suggestion on how achieve correctly? why happen? giving px value works best in scenario. percentage typically used when creating shapes (in case, circle) input{ border-radius:10px; } i believe this you're going for. giving borders percentage mean different based on width , height. using px gives consistent look.

anyone know how render specific mip-level texture? currently binding mip-level texture by: glframebuffertexture2d(gl_framebuffer, gl_color_attachment0, gl_texture_2d, textid, mip-level); then later in code, this: glbindframebuffer(gl_framebuffer, fbo_id); drawarrays(...); but shader not executed!!! if textid other 0, should generating gl_invalid_value error. gl_invalid_value generated if level not 0 , texture not 0. i suggest take @ glframebuffertexture2d opengl es . valid want in normal opengl not in opengl es :-\

i have opengl widget, want render line dependent of mouse positions, follows: glpushmatrix(); glenable(gl_blend); glblendfunc(gl_src_alpha, gl_one_minus_src_alpha); glcolor4f(1, 0, 0, 0.1); glscalef(a, b, 0); glbegin(gl_lines); glvertex2f(pushedx, pushedy); glvertex2f(currentx, currenty); glend(); glflush(); gldisable(gl_blend); glpopmatrix(); where: pushedx=buttonpresscoordinates.x(); pushedy=buttonpresscoordinates.y(); currentx=mousecurrentposition.x(); currenty=mousecurrentposition.y(); the rendering goes good, , line rendered required when move mouse connecting line pushed , current coordinates. but: the issue is, when press mouse somewhere on widget , don't move it, generates randomly (as think) (x,y) , connects line coordinates of mouse pressed position. though when start moving mouse starts working fine. please, fix bug. edit the code of assigning current val...

i wonder if there difference in performance between checking if value greater / smaller another for(int x = 0; x < y; x++); // y > x and checking if value not equal another for(int x = 0; x != y; x++); // y > x and why? in addition: if compare zero, there further difference? it nice if answers consider assebled view on code. edit: of pointed out difference in performance of course negligible i'm interested in difference on cpu level. operation more complex? to me it's more question learn / understand technique. i removed java tag, added accidentally because question meant not based on java, sorry. you should still clearer, safer , easier understand. these micro-tuning discussions waste of time because they make measurable difference when make difference can change if use different jvm, or processor. i.e. without warning. note: machine generated can change processor or jvm, looking not helpful in cases, if familiar assembly c...

we've building small self-rendering javascript component embedded on many third party sites. our javascript depend on several common libraries (zepto, hogan, etc). what's best way isolate our javascript polluting global namespace or interfering other javascript on third party site? there special error handling considerations/wrappers should use ensure our javascript doesn't prevent rendering? the goal have single script embedded on third party site renders interactive content in dom, otherwise remains entirely isolated. after reading more this, i'm going use closure based wrapper , jquery noconflict mode so: (function(window, document, undefined){ // inject contents of jquery-2.0.3.min.js here var $ = jquery.noconflict(true); //remove global jquery , alias locally //define application classes , init here using local $ })(window, document);
