You have to define which type of exception you want to catch. So write except Exception, e: instead of except, e: for a general exception (that will be logged anyway). Other possibility is to write your whole try/except code this way: try: with open(filepath,’rb’) as f: con.storbinary(‘STOR ‘+ filepath, f) logger.info(‘File successfully uploaded to ‘+ … Read more
Make sure you’re setting Response.StatusCode to something other than 200. Write your exception’s message using Response.Write, then use… xhr.responseText ..in your javascript.
This has been possible since Java 7. The syntax for a multi-catch block is: try { … } catch (IllegalArgumentException | SecurityException | IllegalAccessException | NoSuchFieldException e) { someCode(); } Remember, though, that if all the exceptions belong to the same class hierarchy, you can simply catch that base exception type. Also note that you … Read more

You would normally only ever consider doing this at the outermost level of your code if for example you wanted … Read more
Use TestCase.assertRaises (or TestCase.failUnlessRaises) from the unittest module, for example: import mymod class MyTestCase(unittest.TestCase): def test1(self): self.assertRaises(SomeCoolException, mymod.myfunc)
For Python 2.6 and later and Python 3.x: except Exception as e: print(e) For Python 2.5 and earlier, use: except Exception,e: print str(e)
traceback.format_exc() or sys.exc_info() will yield more info if that’s what you want. import traceback import sys try: do_stuff() except Exception: print(traceback.format_exc()) # or print(sys.exc_info()[2])
The solution was to add these flags to JVM command line when Tomcat is started: -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled You can do that by shutting down the tomcat service, then going into the Tomcat/bin directory and running tomcat6w.exe. Under the “Java” tab, add the arguments to the “Java Options” box. Click “OK” and then restart the service. … Read more
To check the existence of a local variable: if ‘myVar’ in locals(): # myVar exists. To check the existence of a global variable: if ‘myVar’ in globals(): # myVar exists. To check if an object has an attribute: if hasattr(obj, ‘attr_name’): # obj.attr_name exists.
