java - Load Python class through Jython -

-

i'm trying load python class embedding jython in java application.

the code have far is

         string pythonroot = main.class.getresource("/python").getpath();          pysystemstate state = new pysystemstate();         pyobject importer = state.getbuiltins().__getitem__(py.newstring("__import__"));          pyobject sysmodule = importer.__call__(py.newstring("sys"));          final pystring pythonpath = py.newstring(pythonroot);         pylist path = (pylist) sysmodule.__getattr__("path");         path.add(pythonpath);          pymodule module = (pymodule) importer.__call__(py.newstring("building.blah.again.blah2.test"));         pyobject klass = module.__getattr__(py.newstring("address"));         addressinterface ai = (addressinterface) klass.__call__().__tojava__(addressinterface.class);

the class i'm trying access can found in

 /python/building/blah/again/blah2/test.py

and name of class is

 address

however, gives me exception

 exception in thread "main" importerror: no module named blah2

if place file in directory above, so

 /python/building/blah/again/test.py

this gives me exception

 exception in thread "main" importerror: no module named again

it's if actively refusing recognize directories contains files. can problem here , how might proceed around this?

if added path of module python-path, did via path.add(pythonpath);, import-command expects name of module, not full path, i.e. pymodule module = (pymodule) importer.__call__(py.newstring("test")); further, should confirm right path added printing contents of path-list. note class-declaration in test.py must extend address-java-interface tojava work (i mention because common source of error).

that said, way of using jython appears cumbersome me. if you, stuff (adding path, doing import) in python-script, run via org.python.util.pythoninterpreter (http://www.jython.org/javadoc/org/python/util/pythoninterpreter.html) , retrieve class-pyobject via eval or get-method.

i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
