javascript - Request dispatching from one JSP to another JSP -

-

I am currently working on a payment gateway type project. If there is a verification error in the back end, first I want to show an error message on my JSP page (payment gateway) and after 10seconds, I send the object (error code) to my JSP merchant (webpage of the merchant) Want page

Currently, when I try to send and forward in my JSP page, my error message / content is not shown in jsp. Instead of showing my error messages, it is just waiting for 10 seconds and the object moves the merchant forward. Because I hope that I am not allowing permission / response to my JSP in sending a dispatch. Correct me if I'm wrong.

Please suggest me a good way to handle this situation?

I am trying to do this in my JSP page .. 

  & lt; / Head & gt; & Lt; Body & gt; & Lt; form: form method = "post" commandName = "item" & gt; & Lt; Form: Errors Path = "*" cssClass = "errorblock" element = "div" /> & Lt; TR & gt; & Lt; Td> Response code: & lt; / Td> & Lt; Td> $ {Item.responseCode} & lt; / Td> & Lt;% = "Test"% & gt; & Lt; / TR & gt; & lt;% Thread Sleep (10000); // sleep 10 seconds request dispatcher rd = request.getRequestDispatcher ("/ merchant.jsp"); //rd.include (request, feedback); Rd.forward (request, response); & Gt%; & Lt; / Body & gt;      
 
 You can not output output to Jsp and Then go to the thread or something else, the webserver does not send the output until the code is executed, because we are not able to see your code, I think you are trying to output error, thread Go, and then send a redirect, whatever it will have to write it and then immediately send it to the client, redirection Send a message.  
 Your best bet would probably be to use Javascript to send a redirect to the page on which you are redirecting customers to display the error.  
  Edit: Since the comment formatting is odd: the servlet was not going to wait 10 seconds and was to send the redirect again, because all the processing responses are done before sending, the fact After that the only way to send more data would be Javascript, or any other weird black magic, the simplest and most elegant solution would be:   
  & lt; Script ty pay = "text / javascript" & gt; window.location.replace ("http://yourwebsite.com/merchant.jsp"); & Lt; / Script & gt;

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...
