java - Webservice request fails for sequential call in Webshpere 7.0 -


i running error when trying call web service server side of spring based web application. 

javax.xml.ws.webserviceexception: java.io.ioexception: async io operation failed (1),  reason: rc: 55 specified network resource or device no longer available.

the web application developing running on websphere 7.0 / windows server 2008 r2 64bit.

the web service interface implemented javax.iws.webserivce (uses @webservice annotation). in case has 2 methods implemented @webmethod annotation call 2 different methods on web service.

error happens when try call 1st , 2nd methods sequentially 1 after another. calling both of these methods done in same server side function:

public myresponse getresponse (...) {      res res1 = webserviceinstance.getfstcall()      res res2 = webserviceinstance.getsndcall()  }

1st method call succeeds, above mentioned error 2nd call.

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 ...
