So we want to develop a service app (web Service with post/get API). What is language to go for secure, fast, enterprise app for about 2000 employers to use with about 20~40 services for interacting with DB server (which in my case will be Oracle) Dev time a year Dev team of 3. All capable of righting C++ code as well as Java (so they will now them equally bad at the beginning of process)
Definitely java! You might want to check the jee6 tutorial on JAX-WS to get an idea of how web services are created using enterprise java (http://download.oracle.com/javaee/6/tutorial/doc/bnayn.html)
This will also guide you on how to do it using the netbeans IDE (http://netbeans.org/kb/docs/websvc/jax-ws.html)
Cheers!
You'd be masochistic to try this with C++! Definitely Java, J2EE whatever (look at various technologies from groups such as JBoss). The development process will be significantly faster using these existing technologies than writing your own...
The question is not what language to choose but which "architecture" or paradigm.
If you want/need to use SOAP then C++ might be fine, go and google for "gsoap". However I would recomend Java and REST as architecture paradigm, well we would need to know more what you really want to do. Perhaps some RMI or CORBA would be much easier. If you want to play with Java, Groovy or Scala (all languages run on the Java JVM), then google for "restlet".

I would suggest using the Java / Netbeans combination.
Netbeans has a number of tools which makes web service development easy.
Good overview here.
Netbeans allows full use of JAX WS and Metro and is integrated with Glassfish and Tomcat servers (part of Netbeans download) so you can get up to speed really quickly.
you can use either C++ or Java depending what you're implementing. To see an example on C++ check out this great post by IBM Engineers: http://www.ibm.com/developerworks/webservices/library/ws-xml-rpc/

At the moment, I have lot's of Java which does all kind of nifty stuff and I'm happy with it. The code is command line driven which have been great so far, but I recently decided I want to make the functionality available through web-services. Since my is complex and I'm happy with the way it's written , I don't want go through the pain of porting it to other languages. So I set out on a google journey to find out what web servers exist (on a Linux machine, though it's interesting to hear the answer without that limitation).
From what I could find, it seems that there are two viable options: Apache Tomcat and Sun Java Server.
What are the reason to choose one on top of the other? what are the strength of each and what are the weaknesses? Or, perhaps, there is a third one which is much easier, flexible and less cumbersome.
Anyone?
Easy, flexible and not cumbersome, that would be Jetty, but also Simpleweb might be useful. You dont say much about your software so i'm not really sure, but for a command line program, I don't think you need all the JavaEE stuff.
The mainstream servers are these.
I think the Apache Tomcat vs Glassfish (Sun Java Server) discussion is irrelevant for your needs, any would do.
There are many containers for Java web applications, they all have their own strengths and weaknesses. If you're looking for a container to support a business application, you should probably take a look at how they differ and work out which suits your business and IT drivers.
The key thing is that they all support the servlet specification - your webapps can run in any of them - which means you can change your mind easily. Some of them will also support more of the Java Enterprise Edition specs, so may be too heavy for your needs.
If you're just getting started, I'd suggest Tomcat. It's basic, but it's reliable, quick to run and start up, and it's got a really easy web-based webapp deployment interface.
Your question is actually a bit too ambiguous and wide. You can in fact run Java code at any machine you like, regardless of the language you programmed the webbased interface in. You can for example create a PHP based website which interacts with a "backend" Java application (the "command line application" as you call it). The only requirement is to have a JRE at the server machine. Then basically everything as web interface suffices: CGI, PHP, ASP, Python, etcetera, you name it. As long as it has access to the underlying commandline runtime, which is in the PHP example to be done by exec().
But Java, actually Java EE, also provides a web application programming interface: the JSP/Servlet API, the web component of the large Java EE API. This make integration with the "commandline Java application" much more seamless. You can basically just put your application in the classpath and import/access/use it in a Servlet class the real Java way:
YourApplication app = new YourApplication();
Result result = app.doStuff();
// ...
To be able to run JSP/Servlet (JSP is at end actually also a Servlet), you need a concrete implementation of the Servlet API (the whole Java EE is just an abstract specification). Apache Tomcat is good to start with, the other popular alternative being Eclipse Jetty. Those are 'simple' servletcontainers which implements the Servlet API, with Jetty being a more embedded approach of it (you can configure and run it as a "plain vanilla" Java Application). But if you need to support/cover the other aspects of the Java EE API as well, then you need an application server, such as Sun Glassfish or JBoss AS (both which by the way uses Tomcat as the servletcontainer part).
To learn more about JSP/Servlet, I can recommend the Coreservlets.com tutorials.
Apache Tomcat should do good.
The standard concept for running code inside a web server is the "Servlet API" from Sun.
Essentially it provides a few interfaces which the web server uses to invoke your code, and defines how the web server should behave. This allows you to write very generic code that can run in a variety of web containers which implement the Servlet API. See the Wikipedia article for details - http://en.wikipedia.org/wiki/Java_Servlet.
They come in all sizes too, depending on your needs. Some small enough for embedding in your own application, some very big. The servlet API allows you not to care.
For a beginner, the quickest way to get up and running, is to download the full version of Netbeans which includes full support for doing this kind of work, and has a built in servlet container.
i am currently using php as backend language in webdevelopment. but im wondering what you need to install to get running with python and java.
with php i need apache and mysql.
can i use those for java and python too?
i cant find good guides equivalent to LAMP/MAMP/WAMP so i understand the parts when using either java or python. would be great if you could give me some good links on the installation and what is required.
and i have read that its easier with python. but is this the only advantage of using python instead of java. cause with java i can create java applets, desktop and mobile applications. they all tend to have java installed. but not python.
so why should i use python instead of java.
I can only give suggestions for web development in python:
Use Tornado - A non blocking web server.
Use Jinja2 - A templating engine.
Use MongoDB - A schema less database server | You can also use any RDBMS according to your requirement.
Above 3 tools are enough to build a web application in python.
or you can always choose Django - The giant web framework with all the features required to build a scalable web application in python.
You need to look into the Web Application Framework subject. Some SO pointers:

Good luck.
web2py is a python web framework that is completely self-contained, runs portably off a USB drive even. The manual is available on scribd, and after an hour or two of tutorial you will have a pretty good idea of what a python web framework will be like. I can't comment on Java at all.
EDIT: Django and web2py are very, very similar. I think I prefer web2py because it does more for me that I don't have to do, but from the POV of, say, Java frameworks, Django and web2py may as well be the same thing.
I am a .NET Developer with about 5 years of web development experience using Microsoft technologies starting with classic ASP to ASP .NET 3.5.
I do have a little background in Java as well and can write/understand Java code very easily. I am looking for resources (online, books) that are compatible with my .NET experience. I am only interested in web development in Java and want to start at intermediate level even if it may require me to look up some details.
What path or resources would you recommend for intermediate .NET web developers to gain equivalent proficiency in Java web development tools?
Get an IDE: IntelliJ (my preference), Eclipse, Netbeans;
Get an application server: Glassfish (my preference; either v2 or v3 Prelude), JBoss or, if you're feeling adventurous, SpringSource dm server;
Get a JDK eg 6u11;
Get a copy of Spring 2.5.6 (or 3.0M2 if you're feeling adventurous);
Get a copy of the Spring reference documentation;
Put the pieces together.
Get yourself a copy of eclipse, and just start reading other people's code, and reading some java docs. The Java website has all the docs online, and they're one of the best language specs I've seen.
Really, if you know C# pretty well, Java should be a cake walk. The languages are pretty similar, so you just need to get to know the different frameworks.
Probably the most helpful book in regards to learning Java's web development framework, Java Server Faces:
Core JSF
- Great examples and explainations throughout on the whole process of using the JSF Framework.
And of course for anyone new to Java I would recommend:
Effective Java
- Covers various design patterns and practices.
In my experience that official Java exams are better than the .Net equivalents, so it may be worth starting there?
Search for a servlet/JSP tutorial (Good, albeit a little old, example here).
You'll get basic knowledge of Java web application development.
Whatever your level is, JSF for Nonbelievers is the best introduction to JSP/JSF.
I'd check out Bitter Java.
It's a book that shows you the wrong way to do things, why it's wrong, and then it shows you the right way.
It pretty much falls in line with the evolution of the j2ee framework. Started with servlets, then moved into jsps, then command pattern, etc.
Im porting a project from php to java. The project is a web-app based on php and ajax techniques with a javascript front-end. What java-frameworks would you use for something like this?
Does the result have to be written in Java, or does it just have to run on the JVM? In the latter case, you might want to consider Grails, which uses Groovy, a Java-based dynamic language that compiles to Java byte code and has full access to the Java standard API.
How well do you know Java?
Why are you porting it?
I can't really tell based on your description, but there are lots of Java web frameworks out there. Pick one. I prefer Spring.
I fear that you're about to be very disappointed. I anticipate a lot of questions like "Why can't I do X in Java? It's easy in PHP!"
Apache Wicket is a possible java based web framework you might consider. The default would be the java servlet and jsp frameworks.
without seeing the source code - you will need a complete rewrite. just "porting" will probably not work.
out of all available frameworks i'd recommend two: wicket if you want clean lightweight technology. with ajax. jsf/seam if you are in a corporate environment where it it easy to get tons of experienced developers.
I really like Stripes.
There's a really good book out on it too. Stripes ... and Java Web Development is Fun Again.
This question seems to come up alot. Related:
What Web Application Framework for Java is Recommended?
Best java mvc framework implementation for web apps
Does it make sense to use a framework for a simple java web app?
What language/platform to choose for a new web application?
In my opinion you would still do the same but generate the html with JSP and javabeans instead of php. javascripts and ajax will still work without a problem if the outputed html is the same.
It depends by the size of your project, the features and your resources.
If the project have'nt a lot of particular needs you can use Struts. Thsi is a stable framework, not really advanced but simple and powerfull for the development.
Another frameworks more recent and advanced are Spring and Wicket.
Before you start, I recommend you to do a check-list of your need:
Do you must porting a O/R mapping too?
Have you a stable developer knowing Java/J2EE?
Do you think to add some feature during the porting or in short-run?
etc etc
good luck! :)
I would port it to GWT
Google Web Toolkit (GWT) is a development toolkit for building and optimizing complex browser-based applications. Its goal is to enable productive development of high-performance web applications without the developer having to be an expert in browser quirks, XMLHttpRequest, and JavaScript. GWT is used by many products at Google, including Google Wave and the new version of AdWords. It's open source, completely free, and used by thousands of developers around the world.
I need to implement webservices in an upcoming project and wanted to know what are the main points to base the decision on whether to implement using java or .NET
I'm a C++er...
If you're a Java shop use Java. If you're a .NET shop use .NET.
There really is no difference that makes one of the two languages superior to the other in regards to web services.
Possible consideration - .NET pre 3.5 only provided support for SOAP based services, but I believe the 3.5 WCF offers REST and SOAP now.
There's no real difference from programmer's point of view (implementation).
For me, a reason to pick Java is that all tools and infrastructure are free/open source. OS, deployment web server, databases, IDEs and developer tools.
I have plenty of experience with both, and both will certainly do the job.
However I tend to prefer Java over .Net for things like web services for the following reasons:
It's cross-platform, which gives you much better options on the hosting side (e.g. running a big Linux cluster on Amazon EC2)
The library ecosystem is larger and more mature, especially on the server side.
I prefer the more flexible open source philosophy to "the only way is Microsoft". Vendor lock-in is always a bad idea for your enterprise architecture in the long run.
You can optionally use awesome languages like Clojure or Scala on the JVM
Ultimately though, I'd go with the one your team has the most skills with. This will determine what you are most productive with, which is usually most important if your main objective is to deliver value quickly.
It's a personal decision, usually determined by the technology already in place or the skill set of the developer(s) writing the services.
i've never really developed web services in java, but i have in .NET and if you're using Visual Studio they're an absolute cinch to whip up (i expect they're a little more difficult to do without the aid of VS).
if you're already working in java, and don't have any .NET stuff in place, stick with java - it'll save you a lot of money (if you were to get Visual Studio in, as i mentioned), and possibly some time involved in learning the specifics of .NET
In my experience, Web Services are a bit more tightly integrated into Visual Studio than they are into Java's editors.
The Eclipse IDE doesn't even have JAX-WS (Java standard web services stack) support built in, opting to use Apache Axis 1 instead.
Netbeans supports JAX-WS, though.
I personally prefer .NET to Java for many reasons I don't want to go through, since it doesn't really matter and is more a personal preference than a strict guideline I can recommend.
If you have Java infrastructure in place or using a platform other than Windows for your server applications, I strongly suggest Java. However, if you don't have anything in place and running on Windows platform, .NET is pretty cool in that area (WCF/ASMX/WSE/...).
As you say you're a C++ - er you'll probably find .NET easier as you can target it directly from C++.
I'm a Java guy, but I think Web Services are easier to code in .NET. Visual Studio takes care of everything, in Java it takes a bit to get started.
A bit of a problem in some projects with JAX-WS is, that SUN ships the "old" version 2.0 with Java 6. If you want to use the current version, it's some work to make it run with Java 5 and Java 6.
If your app must be portable, you should obviously choose Java. Otherwise I would say it's just a choice of your preferred language, since the above issues are really small (maybe you want to choose Axis or something else anyway, I haven't worked with something other than JAX-WS yet).
IMO if you want to do SOAP, then its a heck of a lot easier to use .NET and WCF. However, I've found REST to be a bit tricky with WCF, and had to implement a custom XML parser to do it instead of using their built-in one.
You probably want to consider your hosting environment too. If you are going to serve this from Windows hardware, you can drop .NET WCF web services into IIS. If you are going to run a Linux/Solaris server, then it isn't even a question...
I suggest implementation with JSP ,it provides a robust platform for development
I prefer JSP to ASP or any microsoft techonolgy!
