parsing - Xtext Grammar mixins result in Guice injection error -

-

I am writing an extact grammar which can access documents declared before a function.

Our current grammar defines with hidden (ML_COMMENT, SL_COMMENT, ...) : 

  ML_COMMENT: '/ *' - & Gt; '* /' SL_COMMENT: '//' - & gt; EOL   
 I have now created a second Xtext project with the following grammar:  
  my.OriginalGrammar HID (WS, FUNCTION_BODY with grammar my.DocumentationGrammar , EOL, SL_COMMENT) "http://www.originalGrammar.my" documentation to import Grammar "http://www.documentationGrammar.my" / * Parser Rule * / translate: eds + = DoxExternalDefinition *; DoxExternalDefinition: def = Definition | Lib = CtrlLibUsage | Comment = ML_COMMENT; FunctionDefinition: aml = AccessModifiersList ts = TypeSpecifier? F = function '(' pl = parameter type list? ')' / * Cs = compound statement / / // compound statement is ignored; // Terminal DOXYGEN_COMMENT: ML_COMMENT; Terminal FUNCTION_BODY: '{' - & gt; '}';   
 I have created dependency in the plugin and added this to  
  beam = standaloneSetup {scanClassPath = true platformUri = "$ {runtimeProject} / The following two lines can be removed if the Xbase has not been used registerGeneratedEPackage = "org.eclipse.xtext.xbase.XbasePackage" registerGenModelFile = "forum: /resource/org.eclipse.xtext.xbase //model/Xbase.genmodel/ "// We need to register super.generatedEPackage to super genmodel =" my.OriginalGrammar. OriginalGrammarPackage "registerGenModelFile =" forum: /resource/my.OriginalGrammar/model/generated/OriginalGrammar.genmodel "}   
 now my thirty Ministers plugin project, I standalone fashion want to use the parser in a So I created the following Parsr file (based on the example :):  
  import java.io.IOException; Import java.io.Reader; Import java.nio.file.Path; Import org.eclipse.emf.common.util.URI; Import org.eclipse.emf.ecore.EObject; Import org.eclipse.emf.ecore.resource.Resource; Import org.eclipse.xtext.parser.IParseResult; Import org.eclipse.xtext.parser.IParser; Import org.eclipse.xtext.parser.ParseException; Import org.eclipse.xtext.resource.XtextResource; Import org.eclipse.xtext.resource.XtextResourceSet; Import my.DocumentationGrammar.DocumentationGrammarStandaloneSetup; Import com.google.inject.Inject; Import com.google.inject.Injector; People class DoxygenParser {@Inject Private IParser parser; Private Injector Injector; Public DoxygenParser () {setupParser (); } Private Zero Setup Parser () {Injector = New Document Grammar StdLon Setup () CreateInjectorAndDoEMFRegistration (); Injector.injectMembers (this); } / ** * Using an extext parses the data provided by an input reader and returns the root tree of the object tree as a result. * @The Ultimate Reader Input Reader * Returns Root Object Node * @ Throw IOE Exceptions When the error occurs during the parsing process * / Public eObaked Pars (Reader Reader) throws IOException {IParseResult result = parser.parse (reader); If (result.hasSyntaxErrors ()) {new parseException ("there are syntax errors in the provided input."); } Return result. GetRootASTElement (); }}   
 However, when I try to run it, I get the guise injection errors, such as  
  com.google.inject. ProvisionException: Guice provision errors: 1) Error in constructing the constructor, org.eclipse.emf.common.util.WrappedException: java.lang.RuntimeException: 'can not create a resource for the path: / my / documentationGrammar / DocumentationGrammar.xtextbin '; A registered resource factory is important   
 I know that the parser should be "correct", since I use OriginalGrammarStandaloneSetup, it works perfectly well.   
 
 
 You must ensure that your sub-section also invites the standalone setup of your super language Usually this is generated in the  DocumentationGrammarStandaloneSetupGenerated  class, but please make sure it was properly setup by Xtext. Finally, something like this should be  
  if (! Resource.factor.registry.INSTANCE.getExtensionToFactoryMap () .user ("xtextbin") resource. Factor Registry INSTANCE.getExtensionToFactoryMap () .put ("extextin", new binarygrammer rsssourcefile IMPL ());   
 The  createInjectorAndDoEMFRegistration  method in your setup's call center.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
