I don't have microsoft vista installed. Is there some kind of trial edition windows vista install in a vmware that can let us test for web application compatilibty?
Thanks
Use Virtual PC:
http://www.microsoft.com/downloadS/details.aspx?FamilyID=04d26402-3199-48a3-afa2-2dc0b40a73b6&displaylang=en
And download the application compatibility testing images MSFT provides at:
http://www.microsoft.com/downloads/details.aspx?FamilyId=21EABB90-958F-4B64-B5F1-73D0A413C8EF&displaylang=en
+1 VirtualPC, though the whole expiry thing is incredibly annoying!
However, FWIW there is almost zero difference between IE7-on-Vista and IE7-on-XP, webapp-compatibility-wise. The differences are platform-level security things that won't generally affect you.

Does anyone have any idea how this can be done?
It's my understanding that WebSphere 8.5 traditional is not compatible or will not run on OSX. I am looking for solutions for developers to develop with a WebSphere 8.5 traditional server locally.
Could we setup some servers on a windows machine so they can be used remotely during development?
I downloaded the Eclipse plugin but it gives me the warning saying OS X is not compatible with WebSphere traditional and to give it a remote server address. I tried to point eclipse to a server on a windows PC but it still wants a runtime installation directory.
I found a single thread on WASDev with a similar question talking about runtime stubs with a dead link.
I tried using a liberty server but I get nothing but null pointer exceptions and JMX errors, I don't think this is a valid alternative in my corporate environment.
For developing against WebSphere traditional on OSX, you could try Docker! We've published developer edition versions of 8.5.5.9 and 9.0.0.0, see:
https://developer.ibm.com/wasdev/blog/2016/06/15/websphere-traditional-ibm-http-server-docker-hub/
https://hub.docker.com/r/ibmcom/websphere-traditional/
The Dockerfiles used to produce these images are here, should you want to try building your own instead:
https://github.com/WASdev/ci.docker.websphere-traditional
However, your question is more specific to getting the tools working.
The last I read (and I'll try to confirm/update the answer when I do find it), is that the stubs are part of the full product install for RAD (selectable via Installation Manager).
You're correct that traditional WAS doesn't run on OSX. Remote servers are an option but traditional WAS is considered by some developers to be heavy and slow to restart, so your developers might appreciate something local and more nimble. Liberty is supposed to run on OSX, and things that run on Liberty -usually- will run on traditional, so getting to the bottom of your Liberty problems might be useful. If you haven't already, posting your question on WASDev might reach someone that has a better answer than this one.
Does Windows (some modern flavour) have an mDNS server installed and/or running by default? If so then how does one tell it, preferably dynamically, to start/stop advertising a new service?
If there is no standard then how does one deal with the problem of conflicts trying to run multiple mDNS servers in that environment?
Basically, I want to implement a service that will run on Linux, Windows and Mac OS X and which needs to advertise its zeroconf webserver location using mDNS. On Linux I just use avahi-publish (or install a config file). I'm guessing that the answer will be straightforward for OS X. I'm struggling to find information for Windows.
Starting with Windows 10, Microsoft made strides towards a native Windows implementation of mDNS and DNS-SD.
While earlier iterations have been limited to UWP apps, a general Win32 API has been exposed from at least SDK version 10.0.18362.0 (1903/19H1, May 2019).
Note: This implementation is currently confirmed working only for 64bit build targets, there is an open issue preventing compilation for 32bit targets.
Outdated note from a previous version of this answer:
Early iterations resulted in mDNS network flooding:
Windows 10, in its default configuration, will spam its local networks
by responding to all mDNS requests with null response packets.
This issue was fixed in Windows 10 1511 (10586) and above
Last time I needed one, Apple's Bonjour Print Services for Windows was the most convenient mDNS client for Windows I could find. Only 5MB.
No, Microsoft doesn't directly support Multicast-DNS.
However, there appear to be several 3rd-party alternatives:

Have also successfully used C++/WinRT for dnssd discovery directly from C++ now. It appears from our perspective to be quicker and more reliable to query services and will let you easily install a watcher to get notifications when devices arrive etc. Of course, this is limited to versions of Windows 10 with support for C++/WinRT, which starts with 10.0.17134.0 (Windows 10, version 1803).
One caveat: We've noticed that it does not provide, nor recognise, a FQDN (trailing dot). So for a device that Bonjour OR Avahi would give an address of mydevice.local., Windows instead gives mydevice.local. Attempting to ping mydevice.local. under Windows 10 (1809) fails.
Windows 10 supports natively mDNS/Zeroconf, but only for modern APIs, not for Win32 applications.
If you have such an application, a third party service is required.

The short answer is to support both Avahi and Bonjour. You'll need Bonjour support to run on OSX anyway, and if a Windows user has installed iTunes they'll already be running it.
As a fallback for Windows users not running iTunes, you can compile Avahi as a library for Windows (with a bit of effort) and bundle it. This is a non-trivial bit of packaging, but the alternative is requiring your Windows users to install iTunes in order to use your application.
I am developing a website which is supposed to have blogging capabilities (which I aim to achieve via wordpress) and a CRM based upon jsp and oracle express (as the website will be deployed over linux server, sql server is not an option).
For development should I choose a server to be installed on a linux machine or should I use linux server? I am sorry if they are very different things and not comparable but I went through both of theirs documentation but couldn't figure out anything.
If I should go for some server to installed on ubuntu, what server should i go for?
I hear that glassfish has much higher support for jsp rather than apache.
Please also keep in mind that the website will go o live on a linux server so please suggest based upon problems or ease of deployment on later stage.
I have a deadline to meet and the people who gave me this work have not been much generous with time. I do not have much linux experience so please pardon my lack of knowledge of the platform.
There seems to be a lot of confusion in your post. Based on your lack of experience with GNU/Linux, I would suggest you use desktop Ubuntu.
The difference between Ubuntu server and Ubuntu desktop is that the server edition is targetted to experienced users, so you get a very minimal distribution. No GUI, nothing preinstalled except the bare minimum.
As for your comment about Apache/Glassfish, the two aren't comparable. Apache is the name of the open source community which looks after a lot of products. Very often people call Apache's httpd just "apache", which is a web server. Glassfish is a Java EE application server (Oracle's reference implementation) so probably a good place to start with Java EE.
I am trying to get the svctraceviewer installed on windows server 2003. I found that it's part of the Windows SDK which is of huge size. Moreover, i wouldn't want install Windows SDK on a server unless it's a hot patch. Is there a way to download or copy the tool separately(probably from windows vista)?
Is there an alternative tool that can be downloaded with reasonable size?
Appreciate your response!
Your right, you probably don't want to push the Windows SDK to all of your servers! :) However, the SvcTraceViewer will run just fine by itself.
We copy it, and some other 'standard' tools to our servers to aid operators/developers in debugging those environments if absolutely necessary.
I don't know of any alternative tools that function as well as it does for specifically reviewing WCF/WF trace logs, but a protocol analyzer (NetMon, Wireshark) will let you see the network traffic. This doesn't help you if your problem is not at the wire level though!
Good Luck!
What are the key use cases for the use of virtualization -- that is, running one or more "virtual PCs" using software such as VMWare and Microsoft Virtual PC -- for software development?
Also -- are there other instances/uses of virtualization that aren't covered by my definition above (use of a tool like MS Virtual PC or VMWare), and that are useful to developers?
My impetus for asking is this StackOverflow comment by Metro Smurf asserting "You'll wonder how you ever developed without it!", regarding use of virtualization.
(Please include just one use case per response. Thanks!)
Application testing in multiple environments is one obvious use of virtualization that I'm aware of. Testing your application on other operating systems (without requiring additional physical computers to do so), as well as testing that involves software that generally only allows you to install a single version on a given machine (such as the Internet Explorer browser; running both IE6 and IE7 on the same machine is not an officially supported configuration), are good candidates for virtual machine usage.
If your build-server is running in a VM, you can make a snapshots of it for every software release in order to be 100% sure that you can recreate the build environment (in case you want to make patches to old releases, for example).
If you set up snapshots of your development environment (and back them up) it can be very easy to resume productivity if your computer breaks down. When your machine breaks down right before your release - and you can resume immediately with all your tools installed and configured, it can be a lifesaver.
The simplest case which applies to my current situation is that we have a complex client-server environment and with virtualization every developer can very quickly get a baseline set of operating systems to deploy their local build to and verify end to end functionality.
Locally you have your dev box, and N client boxes which get re-initialized as fresh OSes each time you want to try a build. Essentially it's the test environment equivalent of a 'make clean' where even the client workstation gets replaced with a new OS.
Quickly distributing environments between team members is a very nice use case to for virtualization especially if you have a lot of various components, tools, etc.. This can save you a ton of time with new hires, contractors, or other individuals who need an environment quickly.
Many presenters use a VM for presentations - it allows them to revert immediately to reset the presentation for the next day, transfer all presentation materials quickly between computers, and not have to show your attendees your messy My Documents folder.
Using virtualization for sales activities is also a great use case. You can take a snapshot at a particular time that you can save as your demo baseline. Then once you run through the demonstration and change the data, etc. you can restore back to your previous baseline for future demonstrations. You can also capture multiple baselines and pick and choose which baseline best fits the upcoming demo.
Test environments. If you have more than one setup that a system needs to be targeted for (e.g. Windows & Linux, XP & Vista) then a machine with lots of RAM and VMWare (or on of the others) is a good way to manage the environments.
Another is developing on one system and targeting another. For example, at one point I did some J2EE work on a workstation running Linux where the client was I.E. 5.5. A VM with Windows 2000 and IE 5.5 would let me test the application.
Reasons I use virtual machines for development.
Isolate different development environments.
Testing environments.
Easy recovery due to computer hardware failure/upgrade.
Ability to "roll-back" changes to your development environment if something corrupts it.
Currently, I am using VirtualBox for my VM setup. I used to use VirtualPC, but I REALLY hated not having any type of "snapshot" feature (like VMware and VirtualBox have).
We develop software for use in our SaaS application, our production environment has a large number of servers and their software environment needs to be absolutely predictable; we can't have ANYTHING installed extra, or absent from our development machines.
Moreover, our application requires a number of different server types in order to function properly (at least 7 last time I counted); mostly they can't be installed on the same (virtual) machine - at least, not without violating the "same software as production" requirement.
In order to have a consistent environment, it's necessary to use VMs. I don't know how anyone ever manages without them.
Snapshots and rollbacks are nice too, but I use them only occasionally (really useful during installation / upgrade tests).
Suppose you're developing a new version of your software, and checking that the upgrade from the previous version works correctly... how long does it take to do a test cycle without being able to rollback the box? Do you have to reinstall the OS then the old version? Can you guarantee that the uninstall really uninstalls everything?
Being able to test/retest your deployment process is a huge savings.
Developing Add-Ins for different versions of Microsoft Office (using Visual Studio Tools for Office).
My main work machine has Office 2007. When I work with Add-Ins for Office 2003 I use a virtual machine with Visual Studio and Office 2003.
I'm suprised that nobody has mentioned the VMware record/replay feature (awesome video demo) which is great for debugging.
I have a headless server running ESXi which runs various machines for building installers (so I don't have to give up processing power on my desktop), automated testing (server is faster than any desktop) and various test environments (about 20 different configurations) so that the support team can easily jump onto a configuration that closely matches a customers system.
When you have one really beefy server running VMs that can be shared between support, test and dev teams, you introduce huge cost savings. In all, we're running ~25 VMs on ESXi (dual-quad core Xeon 2.5G + 8Gb RAM) shared between 5-10 people, some of the developers use Virtual PC and then I use VMware Workstation on my desktop. All of the Mac users here use VMware Fusion as well
I am surprised that no one has mentioned the benefit of increased security by isolating, for example, the database server and web server in different VM's.
Some server applications can use VMs too. When one vm is not used much, the server can locate the resources to other vms.
Some sort of test environment: if you are debugging malware (either writing or developing a pill against it) it is not clever to use the real OS. The only possible disadvantage is that the viruses can detect that they are being run in the virtualization. :( One of the possibilities to do it is because the VM engines can emulate a finite set of hardware.
