java - Which page to make isThreadSafe=false in jsp -


i working database project developed using jsp,servlet. erp project having more 20 users. boss told me use multi-theading in project. please tell me how make decision of pages should muti-threaded , should not.

java multi-threading in jsp not valid argument such because @jbnizet said, web container handles multithreading you.

what can though use multi-threading in cases have code can run asynchronously.

lets assume have scenario :

obj1 = obj2.getvalfromdb(obj3.getsessionid(obj4.getid()));

in this, multi-threading cannot used because tasks have executed sequentially in order result. single thread need...

but in example below...

val = getvalfromdb()+getvalfromsrc1()+getvalfromsrc2();

the sub-results can calculated in separate threads.

so, have make evaluation of code , use multi-threading appropriately.

as isthreadsafe directive in jsps, thing can disable multi-threading (which opposite looking for). specification says:

the use of singlethreadmodel interface guarantees 1 thread @ time execute in given servlet instance’s service method. important note guarantee applies each servlet instance, since container may choose pool such objects. objects accessible more 1 servlet instance @ time, such instances of httpsession, may available @ particular time multiple servlets, including implement singlethreadmodel.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
