Java File parsing toolkit design, quick file encoding sanity check -


(Disclaimer: I've seen many posts here before asking, I found it particularly useful, I only have one

Hi all,

I have an internal Java product that I have created to load the data files in the database (aka A et al. Equipment). I have XSLT changes For the pre-rolled phase, and working as a paradigm within the original file. Can be format, they can be flat data files or XML data files, you specifically configure the steps to load datafeed.

I have not yet noticed the issue of the file I have been encoding (a mistake I know), because all were working fine (in the main) However, I am now coming against file encoding issues, to reduce a long story, the way the A Can be configured with, due to the nature of, I have to find the file encoding of the input file and create a Java Reader object. I want to do a quick discretion with people before plunge into just a few people I can not claim to fully understand:

  1. Adopt standard file encoding of UTF-16
  2. Use input file encoding or to smell
  3. Use Apache Commons IO Library for creating a standard reader and author for all stages (am I thinking that there is no encoding-sniffing API in it?)

Do you have any disadvantages / knowledge to provide any extra in my underlined perspective?

Either way, I can rely on back compatibility with any data using its current approach to running Java Runtime, to fix the encoding of windows-1252?

Option 1 followed me And compatibility (definitely for long lasting), though "the right way" (the option in the right way breaks the compatibility normally backwards), perhaps with the additional thought of whether the UTF-8 is a Good choice will be there.

As appropriate if you have a known set of limited, known encodings that you have known that your sniper has correctly identified and identified.

Another option here is to use meta-data, and there is a strong alternative), which tells your code that the data was provided according to UTF-16 standard and behave accordingly, otherwise Standard it before moving ahead to UTF-16.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
