python - subprocess.call() fails on Mac and Linux -


I'm running a strange problem with the subprocess.call () function. I'm trying to use Java's Jar command subprocess.call (). Here's the code: 

  imported OS import subprocess def read_war (): war_file_path = "JacobBit-WebEp-2.6.5.wire" Java_Home = OS Environment ['java' ham '] jar_path = OS Path.join (java_home, 'bin', 'jar') jar_cmd = jar_path + 'tvf' + war_file_path "to execute the command" command: "+ jar_cmd subprances. I am using Python v2.7.3 on both Windows and Linux (Oracle Enterprise Linux). In Windows 7, I see the content of the war file that I see. On Linux, however, I'm seeing 'no such file or directory' error.   $ python is a command to execute example.py: /usr/local/tools/jdk1.7.0_15/bin/jar tvf jackrabbit-webapp-2.6.5. War traceback (most Recently Call End): File "example.py", line 24, & lt; Module & gt; Read_war () file "example.py", line 23, read_war subprocess.call (jar_cmd) file "/usr/local/tools/Python-2.7.3/Lib/subprocess.py", line 493, call return popen (in * Popenargs, ** kwargs) .wait () file "/usr/local/tools/Python-2.7.3/Lib/subprocess.py", in line 679, __init__, errread, errrite) "/ usr / local / Increase child_exception in Tools / Python-2.7.3 / Lib / subprocess.py ", Line 1249, _execute_child OSError: [Error 2] No such file or directory $   
 I have tried the command '/usr/local/tools/jdk1.7.0_15/bin/jar tvf jackrabbit-webapp-2.6.5.war' from the command prompt and it works fine. Therefore, nothing is wrong with the command I have tried different combinations of subprocess.call () - passing a string, passing a list etc. None of them work. Any help at all will be appreciated.   
 
 
 Add Shell = is true for calls. On Windows, the CreateProcess command parsing string to separate command commands and its various arguments. On Linux, you only receive string processing if you specifically tell the sub process to call the shell. Otherwise, it considers the entire string that you had handed over as a command and you do not get very far.  
  subprocess.call (jar_cmd, shell = true)

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
