java - How to use Jena TDB to store local version of Linked Movie Database -

-

i have local version of linkedmdb in n-triples format , want query it. now, want use jena tdb, can store data can used querying later. checked documentation tdb java api, unable load n-triples file , query sparql. i've used following code:

string directory = "e:\\applications\\tdb-0.8.9\\tdb-0.8.9\\bin\\tdb";         dataset dataset = tdbfactory.createdataset(directory);          // assume want default model, or named model here         model tdb = dataset.getdefaultmodel();          // read input file - needs done once         string source = "e:\\applications\\linkedmdb-18-05-2009-dump.nt";         filemanager.get().readmodel( tdb, source, "n-triples" );

and got following exception

exception in thread "main" com.hp.hpl.jena.tdb.base.file.fileexception: not directory: e:\applications\tdb-0.8.9\tdb-0.8.9\bin\tdb     @ com.hp.hpl.jena.tdb.base.file.location.<init>(location.java:83)     @ com.hp.hpl.jena.tdb.tdbfactory.createdataset(tdbfactory.java:79)     @ tutorial.temp.main(temp.java:14)

reading tdb-backed model java straightforward, see the tdb wiki details. example, could:

// open tdb dataset string directory = "./tdb"; dataset dataset = tdbfactory.createdataset(directory);  // assume want default model, or named model here model tdb = dataset.getdefaultmodel();  // read input file - needs done once string source = "path/to/input.nt"; filemanager.get().readmodel( tdb, source, "n-triples" );  // run query string q = "select * {?s ?p ?o} limit 10"; query query = queryfactory.create(q); queryexecution qexec = queryexecutionfactory.create(query, tdb); resultset results = qexec.execselect(); ... etc ...

as user205512 mentioned, can use tdbloader2 command line on linux or mac, faster on large rdf files. once tdb indexes have been created, can copy files other machines. can load data on linux server, ship files inside tdb directory windows machine continue development.

to run tdbloader command line on windows machine, you'll need cygwin allow run unix-style scripts. you'll need set environment variable tdbroot.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
