jolie Unsupported communication medium: null -


i have problem jolie embedded ol , recursive. in example there calcultator.ol receive messagge "fibonacci" .. request dispatched fibonacci.ol embedded in calcolator.ol. first invoke ok .. next invocation (recursive in fibonacci.ol) fails messagge:

informazioni: [fibonacci.ol] jolie.net.unsupportedcommmediumexception: unsupported communication medium: null @ jolie.net.commcore.createcommchannel(commcore.java:311) @ jolie.net.ports.outputport.getcommchannel(outputport.java:240) @ jolie.net.ports.outputport.getcommchannel(outputport.java:310) @ jolie.process.solicitresponseprocess.run(solicitresponseprocess.java:122) @ jolie.runtime.parallelexecution$parallelthread.runprocess(parallelexecution.java:44) @ jolie.executionthread.run(executionthread.java:469) @ java.util.concurrent.executors$runnableadapter.call(unknown source) @ java.util.concurrent.futuretask.run(unknown source) @ java.util.concurrent.threadpoolexecutor.runworker(unknown source) @ java.util.concurrent.threadpoolexecutor$worker.run(unknown source) @ java.lang.thread.run(unknown source)"

this code of calculator.ol:

include "runtime.iol" include "console.iol" include "operationinterface.iol" include "calculatorinterface.iol"  execution{ concurrent }  interface fibonacciinterface  {   requestresponse: fibonacci( int )( int ) } outputport fibonacciservice  {   location: "local"   interfaces: fibonacciinterface } embedded  {     jolie: "fibonacci.ol" in fibonacciservice }  inputport calculator {   location: "socket://localhost:8001"   protocol: http   interfaces: calculatorinterface }  main  {   [ fibonacci()( response )    {       __op = "fibonacci";       println@console("operation:" + __op)();       fibonacci@fibonacciservice(10)( response )   }] }

and code of fibonacci.ol

include "console.iol" include "runtime.iol"  execution{ concurrent }  interface fibonacciinterface {    requestresponse:      fibonacci( int )( int ) }  outputport myself {    interfaces: fibonacciinterface  }  inputport fibonacciservice {    location: "local"    interfaces: fibonacciinterface }  main {    fibonacci( n )( response ) {      if ( n < 2 ) {        response = n      } else {        {  fibonacci@myself( n - 1 )( resp1 )  |  fibonacci@myself( n - 2 )( resp2 )        };        response = resp1 + resp2      }    } }

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
