Need authoritative source for why you shouldn't throw or catch java.lang.Exception -

-

I have met a coding standards meeting in just one hour and I need a quick reply to this.

The common knowledge among experienced Java programmers is that you do not throw java.lang.Exception or catch (with rare exceptions - no rhyme intentions). The reason for this is not that the statement 

  hold (java.lang.Exception ex) {...}

will also hold uncontrolled exceptions, and most cases It is not what it is intended in.

We have a number of legacy codes written by members of the current team where they capture a subclass of java.lang.Exception, log an error,

  1. They need to stop writing the code like this.
  3. This needs to be fixed to the existing code using anti-pattern

Number 2 means a reasonable amount of refactoring .

If I can, the argument in the meeting will be reduced by showing an article or blog entry by one of the Java community veterans who make this point (i.e. Joshua Block, James Gosling) Google-fu has not done anything yet.

Is anyone aware of an article or blog by a reputed java guru that you should not catch java or nap? exception?

Quick answers greatly appreciated.

Here are some: (JavaWorld)

(Second Edition) In Chapter 9 (Exception) by Joshua Bloch, there may be something on it, although I could not have got anything to catch exception quickly.

About this question (also points for Java Tip 134) - It also tells you to catch exception or even The rule does not have to be broken.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
