i develop java applications eclipse process data. far developed stand alone applications take data file or database, process data, , output results console/file/database. i put application online. never did web development, understanding, difference code needs on web server can http requests users, , return http response based on application's result. i advice on easiest way can this. technology need learn , tools can use making transition easier. separate code code related web stuff. thanks lot! the simplest approach developing java web applications via servlet specification. lets load application servlet container (such jetty or tomcat), handles http-side invocation issue. servlet front-end front end agnostic processing application. since applications require user interface, take @ myraid of possible templating languages available. velocity safe pick. seperate user interface adapter code.

this question has answer here: what java string pool , how “s” different new string(“s”)? [duplicate] 6 answers i confused stringpool in java. came across while reading string chapter in java. please me understand, in layman terms, stringpool does. this prints true (even though don't use equals method: correct way compare strings) string s = "a" + "bc"; string t = "ab" + "c"; system.out.println(s == t); when compiler optimizes string literals, sees both s , t have same value , need 1 string object. it's safe because string immutable in java. result, both s , t point same object , little memory saved. name 'string pool' comes idea defined string stored in 'pool' , before creating new string object compiler checks if such string defined.

i starting learn xcode , objective-c , reading 3 different books on topic currently. of these books refer file called "appdelegate" (my_first_projectappdelegate.m, my_first_projectappdelegate.h) said "created project" (i creating "cocoa application"). these files not present when create new project. seem not 1 having problem (see http://pragprog.com/titles/dscpq/errata ). is there more information appdelegate? current practice on how deal missing appdelegate? using xcode version 3.1.4 on mac osx leopard. appdelegate nothing more common nsobject class needed connections in mainmenu.xib. can recreate own: create class, name appdelegate open mainmenu.xib , add nsobject object object palette in object inspector's identity tab (the last one) set object's class appdelegate (you should autocomplete) ctrl+drag application object newly created appdelegate object , choose "delegate" opened panel.

i working on project stores multiple versions in same svn repo in different directories. ease of reference coders working on project i'd able add commented tag # $revision: 144 $ however, instead of file revision should contain simple version number so: # $version: 1.63 $ # $version: 1.64 $ # $version: 2.0 $ is there way subversion automatically specific directory , sub-directories new files added those? stores multiple versions in same svn repo in different directories sounds suspiciously tagging described in svn documentation. can instead? svn automatically keep track of revision files came from, won't have embed in files themselves.

i playing around small mfc-wizard-generated application, in visual c++ 2010, , decided put own bitmap resources replace three-cubes mfc bitmap shows in ribbon ui application button, aka "marble". the original appeared use black (0,0,0) transparency color, unable determine mfc ribbon (mfc-feature-pack stuff) stuff in visual studio 2010 determine transparency on bitmap used ribbon's main icon. the properties of ribbon (idr_ribbon) show image=idb_main, , idb_main 32x32 bitmap in bmp format, loaded disk file called main.bmp. some of bitmap resources in project have looks expect: magenta color becomes transparent, mfc main bitmap did not use color scheme or palette. here example of actual results, hope show results not wanted: incidentally, not seem possible use icon resource in application button, little mystified how pull off transparency in it. translucent png, perhaps? did know bmp files can have alpha channels?

i have linq returns correct data. var numemails = (from row in emailbatchproposal row.emailbatchid == emailbatchid select row.emailbatchproposalid).count(); however, if understand linq correctly, not perform optimally. grabs data , walks through list , counts rows. i'd linq (in background) use like: select count(*) ... i trust performance reasons obvious. does know proper way this? actually, if linq query used collection implements iqueryable , supports translation underlying sql variant, quite basic functionality translate count function example correctly.

what best approach take when pulling model objects multiple datasources? for example have application has has data stored in mysql database using hibernate. if wanted store other objects in ec2 or google app engine? understand dao's abstract implementation of working particular data source, entities themselves? at first thought annotating entities jpa annotations great solution, seems i've tied entities down particular implementation. in case of app engine example, of these annotations make no sense. it seems need pure pojo class represent entities, entirely free of persistence logic. if wanted model dog example (yes lame choice, whatever). make sense have abstract dog class, define subclasses work particular persistence solutions: hibernatedog, gaedog, etc. thanks. this great question, if issue isn't new. industry, we've been changing "conventional wisdom" on subject on years. answers today aren't you'd 5 years ago or 5 y...

our workflow has developers working on locally hosted copies of our web application svn source control. have post-commit hooks deploy each new revision designated staging environment running on subdomain. my question is, best way restrict access these staging sites can't stumbled across or god forbid indexed search engines? we'd avoid ip based, have remote developers working unavoidably dynamic ips. i have initial ideas such simple form can hit login credentials either a) give access cookie that's checked when running in staging environment, or b) register current ip address allowed determinate length of time. if can share ideas, previous experience or best practice appreciated if you're using apache simple , basic protection should .htaccess file . if doesn't satisfy needs security, should think implementing own security mechanism . the best solution put staging server in closed network , allow access via secure vpn .

i using resteasy marchal entities json. works okay somehow every thing represented string. e.g. @xmlrootelement(name="testobject") public class testobject { private long value; public long getvalue(){ return value; } } instead of creating like: {testobject:{value:1234}} it creates {testobject:{value:"1234"}} (please note " " around number) so long value converted string. how can avoid that? i've asked on jackson forum resteasy using json marchaling said caused going java->xml->json. there doesn't seem resteasy forum , on seam forum no 1 answer question. does else have same problem? regards okay problem resteasy+seam uses jettison default (and not jackson). jettison marchaling via java->xml->json. the jackson jars aren't included in seam distribution have download resteasy , copy jars mention jackson lib directory. when resteasy finds resteasy-jackson-provider.jar in classpath, jacks...

i writing program needs take array of size n , convert it's hex value follows: int a[] = { 0, 1, 1, 0 }; i take each value of array represent binary , convert hex value. in case: 0x6000000000000000; // 0110...0 it has packed right 0's 64 bits (i on 64 bit machine). or take array elements, convert decimal , convert hexadecimal that's easier... best way of doing in c++? (this not homework) the following assumes a[] ever use 0 , 1 represent bits. you'll need specify array length, sizeof(a)/sizeof(int) can used in case, not heap allocated arrays. also, result need 64bit integer type. for (int c=0; c<array_len; c++) result |= a[c] << (63-c); if want see looks in hex, can use (s)printf( "%i64x", result )

my own cms automatically adds new parameters links in page specify given language. it works quite doesn't put var in same position, giving me link same page/language: www.xxx.yy/index.php?mod=blog&page=3& lang=en or www.xxx.yy/index.php?mod=blog& lang=en &page=3 will search engines smart enough detect both urls same? or detect 2 different urls , therefore mark them duplicated content? i fix issue anyway, i'm curious since long time ago. google supports this, explicitly mention example in webmaster blog : like www.example.com/skates.asp?color=black&brand=riedell , www.example.com/skates.asp?brand=riedell&color=black . having type of duplicate content on site can potentially affect site's performance, doesn't cause penalties. our article on duplicate content : duplicate content on site not grounds action on site unless appears intent of duplicate content deceptive , manipulate search engine results. if site...
