I am using MyEclipse to generate Hibernate code for a PostgreSQL database. The issue is that this is the only reason I'm using MyEclipse. I would like to use some kind of command line tool to easily generate this code. I've seen some mention of such tools but I can't find anything solid. It seems like what I want to do is pretty simple. I hate to fire up this IDE and go through all this stuff just to do some simple code gen.
What's the best way to do this simply?
Yes, you can do it using ant from command line like this.

I hope someone have already faced an issue to verify that application shows correct data from database. I reviewd how groovy used SQL, but I have no idea where and how I should do that. I'm just starting to use gradle+Spock+Geb for testing application. I have a few files where I described a couple of pages from application, a couple of modules and a file with spock specification. Where and how I need to connect to Oracle DB, use SQL and compare result's data with application's ones?
P.S. I write everything in notepad++ and launch from command line writing 'gradlew firefoxTest'. Does exist any more comfortable way to work with gradle+spock+geb?
Thanks in advance.
Because there are no other answers, I wanted to provide a solution someone at my company thought of. This assumes you already have a project that uses some sort of JDBC. In our case it is JDBI.
The idea is to extend Classloader and then use that to directly access the data access object class via the JVM. That idea should work.
I have not tested it out because it doesn't completely fit our use-case. I'll admit that this does not completely apply to your use case, but technically you could just run the jar of an existing project, which can access the database.
I just want to know about the best way to store simple data in wfp application. I'm using SQL CE, but sometimes I need to store simple data (for instance one string). I don't want to use for it db, and I think it's the right decision.
Could you please give me a guidance on how should I do that in best way or any useful resource?
Is there any particular features data settings storage for pattern MVVM?
Thank You.
Use Settings for exactly this scenario. It's simple, allows per user and system wide scenarios and is build into Visual Studio nicely.
Double clicking on Settings.settings in the Properties folder of your project (in Solution Explorer) brings up the editor and you can access these in code with something simple like Properties.Settings.Default.StringPropertyX.

if you're going to be upgrading in the future, I suggest that you create a small abstraction layer that you can upgrade to using any DB or other source, when you need to.
Until you do the upgrade, I would suggest a simple XML file using XDocument and XElement (and the rest of that api).
The reason why I am suggesting this is because you can use Linq on them easily and this enables you to change the provider in the future without any problems.
here is the MSDN on XDocument http://msdn.microsoft.com/en-us/library/system.xml.linq.xdocument.aspx .
I hope this proves to be helpful to you ;-)
Cheers,

p.s. lemme know if this is what you needed or not!
If you publish the application through ClickOnce then you can use IsolatedStorage. It is pretty easy to use, just a few lines of code. You can learn how to use it on WPF isolated storage.
If you don't publish it through ClickOnce then I would suggest you keep it simple and use static class.
you can use file system.. try to create xml file or csv file in the wpf app directory...
you can read and write to same file.. so that you can save what ever you want to that file and read from the same file..
Just getting started with Dapper. I'd like to use it, but I have to be sure that it will work in a medium-trust server situation. I've googled for answer without any luck.
Thanks.
SecurityException - Dapper on shared hosting
As per the link above, it doesn't look like this is possible.
Dapper actually does work but in a limited way. I've gotten the Get methods to work fine but the updating and inserting seems to be the major problem area so I just manually do those. Oh well. I like Dapper too much to drop it completely.
How can I store, for example, the body of a method in a database and later run it? (I'm using Delphi XE2; maybe RTTI would help.)
RTTI is not a full language interpreter. Delphi is a compiled language. You write it, compile it, and distribute only your binaries. Unless you're Embarcadero, you don't have rights to distribute DCC32 (the command line compiler).
However, the JVCL includes a delphi-like language subset wrapped up in a very easy to use Component, called "JvInterpreter". You could write some code (as pascal) and place it in a database. You could then "run that code" (interpreted, not compiled) that you pull from the database. Typically these should be procedures that call methods in your code. YOu have to write some "wrappers" that expose the compiled APIs that you wish to expose to the interpreter (provide access to live data, or database connection objects, or table/query objects). You're thinking that this sounds perfect right? Well, it's a trap.
Beware of something called "the configuration complexity clock". YOu've just reached 9 o'clock, and that's where a lot of pain and suffering begins. Just like when you have a problem, and you solve it with regular expressions, and "now you have two problems", adding scripting and DSLs to your app has a way of solving one problem and creating several others.
While I think the "DLL stored in a database blob field" idea is evil, and absurd, I think that wanton addition of scripting and domain-specific languages to applications is also asking for a lot of pain. Ask yourself first if some other simpler solution could work. Then apply the YAGNI principle (You Ain't Gonna Need It) and KISS (keep-it-simple-smartguy).
Think twice before you implement anything like what you're asking about doing in your question.
Your best Option, IMHO, is using a scripting engine and storing scripts in the database.
Alternatively you could put the code in a dll and put that dll in the database. There is code for loading a dll from a resource into ram and processing it so it can be used as if it was loaded using LoadLibrary, e.g. in dzlib. I don't really know whether works with any dll and in which versions of Windows, but it does with the ones I tried.
I'm looking to create a very small cataloguing app for personal use (although I'd open source it if I thought anyone else would use it). I don't want a web app as it seems like overkill to have an application server just for this - plus I like the idea of it being standalone and sticking it on a USB stick.
My Criterea:
Interface must be simple to program. It can be curses-style if that makes it easer to code. My experience with ncurses would suggest otherwise, but I'd actually quite like a commanline UI.
Language doesn't really matter. My rough order of preference (highest first):
Python
C
C++
Java
I'll consider anything linux-friendly
I'm thinking sqlite for storage, but other (embeddable) suggestions welcome.
Has anyone done this sort of thing in the past? Any suggestions? Pitfalls to avoid?
EDIT:
Ok, it looks like python+sqlite is the early winner. That just leaves the question of which ui library. I know you get tkinter for free in python - but it's just so ugly (I'd rather have a curses interface). I've done some GTK in C, but it looks fairly un-natural in python. I had a very brief dabble with wxwidgets but the documentation's pretty atrocious IIRC (They renamed the module at some point I think, and it's all a bit confused).
So that leaves me with pyqt4, or some sort of console library. Or maybe GTK. Thoughts? Or have I been too hasty in writing off one of the above?
I would definitely recommend (or second, if you're already thinking it) - python with sqlite3. It's simple, portable and no big db drivers. I wrote a similar app for my own cataloguing purposes and it's doing just fine.
I vote for pyqt or wx for the GUI. (And second the Python+sqlite votes to answer the original question.)
I second (or third) python and sqlite.
As far as suggestions are concerned:
If you're feeling minimally ambitious, I'd suggest building a very simple web service to synchronize your catalog to a server. I've done this (ashamedly, a few times) for similar purposes in the past.
With sqlite, backups can literally be as simple as uploading or downloading the latest database file, depending on the file's timestamp.
Then, if you lose or break your flash drive (smashed to pieces, in my case), your catalog isn't lost. You gain more portability, at least 1 backup, and some peace of mind.
