getResource("xmlfile.xml") throws java.lang.NullPointerException -


i have xmlfile.xml in /webcontent/web-inf folder of web project.

i'm trying path of file using;

 url url = this.getclass().getclassloader().getresource("xmlfile.xml");  string filepath = url.getfile();

but it's throwing java.lang.nullpointerexception in second line of code.

what reason this? file available webcontent/web-inf/xmlfile.xml

you should use servletcontext :

servletcontext context = .... // context here inputstream resourcecontent = context.getresourceasstream("/web-inf/xmlfile.xml");

or real path :

string realpath = context.getrealpath("/web-inf/xmlfile.xml");

remember, java ee webapp single (war) file, , therefore file system access components within war not guaranteed. can access objects using standard java class loader mechanism, won't give access paths of war aren't in war's class path (web-inf/classes , web-inf/lib jars). hence fails in case.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
