I have recently changed an application from storing the database username and password in a configuration file (gasp password stored in plain text in a config file, I know, I know). The application now asks the user to type in her username and password before it can continue. The new version of the application now has to interrogate th...
I would like to handle an OracleException thrown when my network/database connection is interrupted, where can I find out what error codes I might can receive? I guess since we are talking about a connection interruption these would be technically TNS errors such as ORA-12560 "TNS:protocol adapter error." But I have noticed a couple oth...

But how do you explain the ...

Hi all! I searched for this for a long time (here too), have read many php codes, but still couldn't find a satisfying answer. It may seem a too wide topic, but it really sticks together - at last for me. Could you please help? In a php website I have PDO as DAL, what is used by BLL objects, and they are called from the UI. Now if some...
I am attempting to write validators under the Spring MVC framework, but there is a glaring omission in the documentation. When calling passing an error to the Errors object most of the methods expect an String parameter named errorCode. These errorCodes, if I understand correctly serve as stand ins for specific error messages. But I can'...
I have a function that returns an id number if the argument exists in the database. If not, it returns null. Is this begging for a null pointer exception? Negative id numbers are not permitted, but I thought it would be clearer to have non-existent arguments returning null instead of an error code like -1. What do you think? private Int...
We are creating an application for a client's website. The website will make a function call to our application to generate XML data, which we will return as a String.

Hi, Currently I'm returning -1 in my custom functions in C if something wrong happens and 0 for success. For instance, working with a linked list and some function needs a non-empty list to work properly. If the list passed as argument is empty, I return -1 (error) and 0 if it's not empty and the function worked without a problem. Shou...

I'm trying to get the "0 of success, nonzero if error" return code from make in Vim. Specifically, I am on Ubuntu and using v:shell_error does not work. After digging around and looking at this question, it seems to be because of my shellpipe setting, which is shellpipe=2>&1| tee The tee pipes the make output back into vim. The shel...
Hi, I'm attempting to run a series of commands programmatically, read the error codes, and detect if these codes indicate success or failure so I can respond accordingly. Currently my commands are using psexec which then launches robocopy. I've noted that while most commands return an error code of 0 if the program is successful, roboco...
Does anyone know how to find a list of all the possible error codes thrown by the ostest utility, and their meanings? I noticed this to be a common problem for people, where they ask about an OCUnit failure with some code 138 or 139 that is completely opaque to them, and somebody who has encountered that particular error number points ou...
