i need simulate http post programatically, i.e., need generate request post variables , send page. to clarify, need simulate behaviour of regular post, not whole thing programatically. need fill in request in same way filled if form post happening, , send browser page expects post. here 1 way it. you send method url , name/value parameters in form of namevaluecollection. method makes http post on endpoint , returns response string. of course depending on what/why you're doing , how many times method called, there maybe other alternatives. until provide more information on specific needs, method enough. the method below uses tasks (.net 4.0) , async methods faster synchronous method next code listing if you're making multiple calls in loop example. static string getwebresponse(string url, namevaluecollection parameters) { var httpwebrequest = (httpwebrequest)webrequest.create(url); httpwebrequest.contenttype = "application/x-www-form-urlencoded...

can python code used java using jython, without modifying python code in way prevent working correctly in cpython? if yes, steps have taken (in java code)? if not, reasons cannot done (so far)? python modules can depend on python versions (e.g. python 3 vs python 2 , may require minimum python version (e.g. 2.6) in case of using dedicated language features introduced in python version) python modules may depend on c extensions won't work jython python modules may use cpython features not available in jython in general: python-only code should work jython - in cases: have test, test, test. written modules provide unittests - should try run tests jython , see what's happening.

take django instance, in manage.py : try: import settings except importerror: sys.stderr.write("error: can't find file 'settings.py'...") seems legit, happens when settings imports non_existant_lib_foo ? well, you're sent on goose chase possible things have done path , etc. of course can use except importerror e: , print out actual error message, if want catch specific error , give bit of advice, above? you're left using regexp more or less or, @ best, guessing "right" module failed importing, , display message. is there better way handle this? basically problem error message wrong - there other reasons why import can fail, not wrong paths. importerror means "you cannot use module, @ traceback find out why", jumped conclusion. if want display "can't find file" should file first. imp.find_module that.
