Re: Java vs. .NET Face/Off

All:

I'm going to be taking a new position doing C#.NET development not on an
iSeries (very sad about that)...

What's the best online resources for C#.NET development besides what Aaron
mentioned here?

I am a newbie both with the program and the language so feel free to

suggest improvements.

This suggestion isn't necessarily an improvement but an alternative.
Whenever I am teaching people C#.NET I always point them to SharpDevelop
which is a free/open-source IDE that is very *similar* to Visual Studio. I
am sure Visual Studio has more meat/features, but many may not need them,
and if you don't want *as much* vendor lock-in then Sharp Develop is a nice
alternative.

http://sharpdevelop.net/OpenSource/SD/Default.aspx

I mostly use it for consuming RPG web services from .NET, but it also has
all the cool features of drag and drop GUI creation.

Cool! Yeah, DLL just means dynamic link library, after all.

I just looked at the IKVM site - Richard, my boss, does all the .Net,

so

I hear about it - have not had time to actually use it - have done quite

a

bit of pre-.Net VB development.

So the site said that you can create a DLL from a JAR file - and that

DLL

is what you can use in .Net. Therefore, you can take jt400.jar and make a
DLL from it that is usable in .Net - and since anyone can use ikvmc to do
it, seems there is no need to publish it.

Got it working with Visual Studio C# Express.

Download ikvm. Run "ikvmc -target:library ....pathtojt400.jar". It
generates jt400.dll

Open Visual Studio C# Express, create a console application project,
right click on project node and add references to jt400.dll and (bummer)
IKVM.OpenJDK.ClassLibrary.dll. Then the following code runs:

===
using System;
using System.Collections.Generic;
using System.Text;
using com.ibm.as400.access;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
com.ibm.as400.access.AS400 as400 = new
com.ibm.as400.access.AS400("system", "user", "password");
IFSFile ifs = new com.ibm.as400.access.IFSFile(as400, "/");
foreach (String s in ifs.list()) {
Console.Out.WriteLine(s);

};
as400.disconnectAllServices();
Console.Out.WriteLine("Done");

}
}
}
===

I am a newbie both with the program and the language so feel free to
suggest improvements.

The major impediment between this and the same solution in plain java is
the extra baggage of the 25 Mb IKVM...dll file. Oh well :)
