google app engine - Objectify - @Embedded Error saving XXX is not a supported property type -

-

When trying to save an entity with an embedded class, the object throws the exception (ObjectTest Dummy is registered):

com.googlecode.objectify.SaveException: test.ObjectifyTestDummy@2485b739: Internal: Error in saving the test.ObjectifyInnerTest is not a supported property type. 

  Import com.googlecode.objectify.annotation.Entity; Import com.googlecode.objectify.annotation.Id; Import javax.preistence.Embedded; Import javax.preistence.GeneratedValue; Import javax.preistence.GenerationType; @ Entity Public Class Objective Dummy {@Id @ javax.preistence.Id @ generatedValue (strategy = GenerationType.AUTO) Private Long ID; @ Embedded private object entry inner; Public long iid () {return id; } Public Zero Set ID (Long ID) {this.id = id; } Public ObjectifyInnerTest getInner () {Return Internal; } Public Zero Setner (ObjectifyInnerTest inside) {this.inner = inner; }}   
 And just:  
  Public class ObjectifyInnerTest {}   
 What's wrong?  
 
 
 I should be ashamed I switched the objective version to 5.0.5, but again cleaned / Did not package. It seems that the target appengine-devserver maven is not updating dependency so I was still working on version 4.x. I do not know why 4.x was not working. Everything works fine with 5.0.5

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
