as - legacy parts of web application depend on apache http client 3, new parts require http client 4.2. apache httpclient 3 , 4 seem live in different packages, theoretically should possible have both versions in same classpath. simple test code works fine. are there potential issues kind of deployment? in general, don't see potential issues. i'd prioritize updating legacy parts of webapp. the specific thing can think of if using both version 3 , 4 parts access same sites , sites used cookies carry session information, maintaining 2 separate cookie stores might result in strange behaviour. example, server side might invalidate sessions.

edit: have figured out problem. there several bugs in posted code came (very) poor understanding of com, notably not understanding calls getdispid doing. i'll update post correctly working code, in case else runs issue. i have c++ application (mfc) embedded web browser. calling c++ functions javascript using: var arrresult = window.external.myfunction (myargs); it works well. send data array using code codeproject article http://www.codeproject.com/articles/88753/creating-javascript-arrays-and-other-objects-from now need send 2-dimensional array. code works me, now. note that, in javascript, 2 dimensional array comes object, not array. so, isarray returns false: omyresult = window.external.vpquery (strquery); if (array.isarray (omyresult)) alert ("this array!"); but successful: if( (typeof arrvpresult === "object") && (arrvpresult !== null) ) alert ("this object!"); so can iterate through this: (var st

for(int j = 1;j<filearray.size();j++) { if(str.contains(filearray.get(end+j))) { } } (assume end number such 30). goal of part when having window length of 30 , filearray size > 30, check if theres after index 30 matches whatever inside window. ex: "i eat piesss aaaabbbbpiesssbbbb" starting beginning of string add first 17 characters arraylist called window. check rest of string starting right after window see if there's matches. space doesnt match add output. keep checking see "piesss" matches. replace second "piesss" wherever first "piesss" occurs. so right im using filearray.get(end+j) check if there's matches within string(str) except doesn't work. there way fix code segment? the replacement part of question still unclear. reasoning use arraylist. i've written code 5 character window search match after splitting string provided. note how 30 , 17 va

i have 3 tables. one product table , has unitsaleprice , other table orderproduct , has column productquantity (how order particular product) , orders add detail of customer's orders. i wrote select statement this: select orderprice product, orderproduct, orders orderproduct.product_id = product.product_id , orders.order_id = orderproduct.order_id , orderprice (orderproduct.productqty * product.unitsaleprice) ; but orderprice column not in 3 tables , dummy column. when run query gives error column not exists. how do this??? you should learn use explicit join syntax: select (op.productqty * p.unitsaleprice) orderprice product p join orderproduct op on op.product_id = p.product_id join orders o on o.order_id = op.order_id;

i picked python not long ago. an example below i have dictionary within list myword = [{'a': 2},{'b':3},{'c':4},{'a':1}] i need change output below [{'a':3} , {'b':3} , {'c':4}] is there way can add value together? tried using counter, prints out each dict out. what did using counter: for in range(1,4,1): text = myword[i] print counter(text) the output counter({'a': 2}) counter({'b': 3}) counter({'c': 4}) counter({'a': 1}) i have read link below compared between 2 dict. is there better way compare dictionary values thanks! merge dictionaries 1 dictionary (counter), , split them. >>> collections import counter >>> myword = [{'a': 2}, {'b':3}, {'c':4}, {'a':1}] >>> c = counter() >>> d in myword: ... c.update(d) ... >>> [{key: value} key, value in c.items()] [{'a

how 1 concatenate 2 byte primitives 1 char in java? i'm trying this: byte = 0x01; byte b = 0x02; char c = (char) (a + b); which gives 0x03. answer want 0x0102. is there no simple way concatenate primitives? i'm surprised there isn't obvious solution, since seems should easy. maybe there , don't see it. :p any appreciated. thanks! by shifting left 8 bits , adding. like, byte = 0x01; byte b = 0x02; char c = (char) ((a << 8) + b); system.out.println(integer.tohexstring(c)); output is 102 as pointed out in comments (by @chrismartin ) bitwise-or (and i'll add might xor ) like char c = (char) ((a << 8) | b); and char c = (char) ((a << 8) ^ b); to achieve same result. since should write dumb code suggest use whichever find easiest understand.

i have requirement check whether string contains particular string or not.for purpose using function of nsstring class called c containsstring . function works fine in ios8 without throwing kind of exception in case of ios7 throwing exception called unrecognized selector sent instance i have used try & catch block prevent exception may know why happening? thanks in advance you can check in framework header. - (bool)containsstring:(nsstring *)astring ns_available(10_10, 8_0); this method of containsstring exist after ios 8 obvious throw error in ios7.... please use below method ios7 , can use above method ios8: if ([string rangeofstring:@"bla"].location != nsnotfound) { nslog(@"charecter found"); } may can solve issue. thanks

i trying started with docker & fig using official boot2docker framework. the fig website includes instructions getting fig working on os-x ( http://blog.docker.com/2014/10/fig-1-0-boot2docker-compatibility-and-more/ ). however, there no references getting fig working within boot2docker under windows. i tried instructions installing fig within boot2docker fig website @ http://www.fig.sh/install.html , , ran roadblock command: curl -l https://github.com/docker/fig/releases/download/1.0.1/fig-`uname -s`-`uname -m` > /usr/local/bin/fig; chmod +x /usr/local/bin/fig apparently boot2docker filesystem read-only, curl command fails. can assist me getting fig working boot2docker under windows? i ended adding alias boot2docker vm (by editing default user .profile): alias fig='docker run --rm -it \ -v $(pwd):/app \ -v /var/run/docker.sock:/var/run/docker.sock \ -e fig_project_name=$(basename $(pwd)) \ dduportal/fig' this c

i trying spark 1.1.0 program written in scala work, i'm having hard time it. have hive query simple: select json, score data when run following command spark-shell works (i need mysql_conn in driver class path i'm using hive mysql metadata store) bin/spark-shell --master $spark_url --driver-class-path $mysql_conn import org.apache.spark.sql.hive.hivecontext val sqlcontext = new hivecontext(sc) sqlcontext.sql("select json data").map(t => t.getstring(0)).take(10).foreach(println) i ten lines of json want. however, when run spark-submit follows problem bin/spark-submit --master $spark_url --class spark.main --driver-class-path $mysql_conn target/spark-testing-1.0-snapshot.jar here whole spark program package spark import org.apache.spark.sql.hive.hivecontext import org.apache.spark.{sparkcontext, sparkconf} object main { def main(args: array[string]) { val sc = new sparkcontext(new sparkconf().setappname("gathering data")) va

i wondering if possible override protected method in 3rd party jar file. guessing can invoke method using reflection, how overwrite it? the method is protected void a(world world, int i, int j, int k, itemstack itemstack) { if (!world.isstatic && world.getgamerules().getboolean("dotiledrops")) { float f = 0.7f; double d0 = (double) (world.random.nextfloat() * f) + (double) (1.0f - f) * 0.5d; double d1 = (double) (world.random.nextfloat() * f) + (double) (1.0f - f) * 0.5d; double d2 = (double) (world.random.nextfloat() * f) + (double) (1.0f - f) * 0.5d; entityitem entityitem = new entityitem(world, (double) + d0, (double) j + d1, (double) k + d2, itemstack); entityitem.pickupdelay = 10; world.addentity(entityitem); } } yes, point of protected methods can overridden subclass implementations in different packages/modules (the default access mode allows same package). it subclass decide if
