Choosing technologies to start up a web project

Hi everybody!
I have to develop a project which uses EJB (as business logic tier, using both stateful and stateless bean), J2EE (as web tier) and Hibernate (as persistency tier, using a db for data storage). Though I know these technologies under a theoretical point of view, I'm not updated with the state-of-art of IDE and developing tools (academic environments are not very helpful under these point of view).
So, I need suggestions about the server/IDE/DBType (Eclipse/NetBeans, JBoss/appServer, MySql/HSQLDB...) solution that I should choose. What do you suggest? For me is important to have good support forum and updated documentation, so that I can solve issues relatively fast. At the same time it'd be great to have the possibility to create all the configuration files, folders, creation command, deployment command from one unique IDE. Of course all the technologies involved should be Open Source.
Thank you for your attention. I hope you don't find my questions too stupid and you will spend time to give me some suggestions. I think it's a very important starting point.

Creating a Dynamic Web Project from existing source?

I don't see this option in OEPE like there is in Workshop for Weblogic. All I can choose from is "Create Dynamic Web Project" which creates a new project from scratch, or "Create Java Project" which has an option in the wizard to import existing source.. however this makes it a vanilla Java project instead of a Dynamic web project.
Did the concept of importing existing code into a project not cross anyone's minds when this plugin was developed? It's as if the expectation was that everyone would use this on their own private projects and there would be no collaborative/parallel development.
What is the recommended way for creating a Dynamic Web project off of existing source code without stomping all over the existing web.xml weblogic.xml?

There are many "import" scenarios, so let's break them down and lay out the support expectations:
1. A java ee project created with base Eclipse using Web Tools Platform project types. This scenario includes both the case where the project creator had OEPE installed as well as the case where there was no OEPE installed. In this case, one should use the import existing projects wizard as the project being included already has metadata that can be read directly.
2. A java ee project created with a non-Eclipse IDE or perhaps completely by hand with rudimentary tools such as notepad. Currently, the way this case is supported is by creating new projects and copying application source into them. Advanced users may be able to configure support in place, but we cannot support users with this approach as the possibility of corruption is high. We are currently working on a set of wizards that will help automate this case. These wizards will be available in the release of OEPE that's slated to ship around the end of 2009 or early 2010.
3. A project created with BEA Workshop. This case is not supported as there are a number of technologies in Workshop that have been end-of-lifed (such as Apache Beehive). Users with Workshop applications should stay with Workshop until they are able to remove dependencies on end-of-lifed technologies. At that point moving to OEPE is recommended. Unofficially (this option is not supported but may work), advanced users may be able to migrate a Workshop app to OEPE, by stripping out all Workshop metadata (.project, .classpath, .settings, etc.) and by pretending that this is scenario #2 (import of a non-Eclipse application). Don't try this if your application still have dependencies on end-of-lifed technologies.

How to create the Custom project System as Web Project

Hi,
I have created a custom project system using this walkthrough. But
this walk through is targeting Visual C# project system. I need to create the Custom project system as Web project and set the start up page as index.html file. How can I achieve this?
Note:
I have got the Custom project system sample from VS2013 SDK samples(https://mpfproj12.codeplex.com/).
But it demonstrate the Custom console applications only.
- Abbas K

Hi,
So you didn't even follow this walkthrough yet? If you did, how did you do it?
I failed to create such a web project system because I finally messed up my VS experimental instance. But it's possible to create a custom web project system, by following this walkthrough. Someone else has successfully made it, check this
link.
The difference is that you have to use web project type instead of the console application project type. You could copy a web project's .csproj file into the VSPackage project and rename it to xxx.myproj. There's an error in the walkthrough that the AssemblyInfo.cs
file should be put into Properties folder and set the "Build Action" property to Content, "Include in VSIX" to true.
We are trying to better understand customer views on social support experience, so your participation in this interview project would be greatly appreciated if you have time. Thanks for helping make community forums a great place.

How does Azure Compute Emulator (or the Azure one) determine if a role is web project or something else ("The Web Role in question doesn't seem to be a web application type project")?

I'm not sure if this is F# specific or something else, but what could cause the following error message when trying to debug locally an Azure cloud service:
The Web Role in question doesn't seem to be a web application type project.
I added an empty F# web api Project to a solution (which adds Global.asax etc., I added an OWIN startup class Startup etc.) and then from an existing
cloud service project I picked Roles and
chose Add
-> Web Role Project in solution, which finds the F# web project (its project type guids are 349C5851-65DF-11DA-9384-00065B846F21 and F2A71F9B-5D33-465A-A702-920D77279786),
of which the first one seem to be exactly the GUID that defines a web application type.
However, when I try to start the cloud project locally, I get the aforementioned error message. I have a C# Web Role project that will start when I remove the F# project. I also have F# worker
role projects that start with the C# web role project if I remove this F# web role project. If I set the F# web project as a startup project,
it starts and runs as one would expect, normally.
Now, it makes me wonder if this is something with F# or could this error message appears in C# too, but I didn't find anything on Google. What kind of checks are there when starting the emulator and which one needs
failing to prompt the aforementioned message? Can anyone shed light into this?
Sudet ulvovat -- karavaani kulkee

Sudet,
Yeah you are right, the GUID mentioned seems to be correct and the first one i.e. {349C5851-65DF-11DA-9384-00065B846F21} means the web application project which compute emulator uses to determine while spawning up role instances.
You might want to compare the csproj of your C# and F# web projects which might give some pointers.
Are you able to run your F# web project locally in IIS? If yes then you will definitely be able to run it on azure so I will recommend to test it in IIS Express first.
Here are some other tips which you can refer or see If you are yet to do those settings
1. Turn on the IIS Express - You can do it by navigating to project properties
2. Install Dependent ASP.NET NuGets / Web Api dependencies (If there are any missing), Reference System.Web assembly
Also I will suggest to refer this nice article about how to create a F# web Api project
http://blog.ploeh.dk/2013/08/23/how-to-create-a-pure-f-aspnet-web-api-project/
Hope this helps you.

That class should be provided by the application server. Double check that the version of Tomcat you have supports servlet 2.4. Also check there are no bug reports against it for this error.

Not able to create a web project with jsf or jsp or struts or spring

Hi,
I am trying to create a dynamic web project with jsf or jstl or struts or spring or any of web options available for a web project, but I am not able to do it.
When I choose any of these options, the wizard asks me to "select an existing jstl/jsf/Spring 2.0 library, or click Add to add a new library." and since it doesn't show any existing libraries there, I clicked on add new library. When I click add, it opens a new dialog box where it has two options :
1. to use spring/jstl/jsf lib from bea web site - when I choose this option, it tries to connect to the bea web site and gives me error that "connect time out". I don't know why it is not able to connect to the internet. I am not able to see the help also. There it gives error "The requested URL could not be retrieved".
2. to use libraries from an existing spring installation - I provide the path of a directory where spring lib are, but then it gives me error that this is not a valid installation.
On another machine, I am able to see the help contents, but still not able to get these libraries from the bea site.
Please help.
Thanks in advance,
Sushma

Hi Sushma,
The issue you are facing has been addressed and will be part of the next release. For the current release, please follow the steps listed below.
Send an email to [email protected] with details on specific facets you are trying to enable on your project.
You will be provided with a url where you can download the required jars and details on how to manually add the jars to the workspace which will prevent the download on demand scenario.
Cheers

Converting Air Project to Web Project in Flash Builder 4

I have an Air project that I need to convert to a web project to post online. I've looked online with no luck so far, but perhaps someone can point me in the right direction.
The closest thing I see to being what I want is if I go to Properties > Run/Debug Settings. In there I tried going to New > Web Application but when I browse for Project it comes up empty, and so is the "Application file" dropdown. I tried screwing around int he Source tab in the same window but it doesn't seem to help much.
Other things that look close to what I want but don't work are when I right click my project, there's a "Add/Change project type" but all options are greyed out and I don't see anything web related in the options anyway.
Also there's Properties > Targeted Runtimes, but there's nothing there I can do.
Then in Properties > Flex Compiler I have "Generate accessible SWF file" checked. But when I try to use that file it won't work in the browser flash player.
So... is there an easy way to convert an Air project to a Web project?
Thanks!

I'm glad (but at the same time sad) someone has had the exact same problem I had.
I've tried a few things (though none successful).
- creating a flash pro project from the fb project
- creating an AS3 project from the as3 mobile project (which runs on air). now this one I thought would work, and it does in Flash Player, however, when I try to run it with the generated html file, all I get is a string of errors.
Here is something that does work.
If you create an AIR project in Flash Pro (I've only tried this in CS5.5), when you publish the project, it will generate the swf and html files and the html file works and the swf runs great. Unfortunately you have to start that way (which sucks for programmers that want the benefits of Flash Builder). I haven't found anything to properly convert it yet.
I hope this is some insight, even a year later.

How to create web project in JDeveloper 11

Hi. I've downloaded the base Java edition of JDev 11 (the one that's 55 MB) and am wondering how to create a web app; didn't need the ADF stuff. I created a WEB-INF folder via Windows Explorer in the project's folder but the app doesn't recognize it. How do you create a web project in this edition of JDev 11's base Java edition? It also doesn't seem to be an option when you choose New. Thanks.

Web Project is an option in the Studio edition, not in the Java edition.

Data Palette not showing Managed Beans for Dynamic Web Project, JSF 2.1

Hello.
I have a problem in OEPE (oepe-juno-distro-win32.zip), where the Data tab in Palette shows no Managed Beans,
even if I created them in the ManagedBeans in faces-config.xml using the Faces Config Editor.
I have created a Dynamic Web Project with these Facets:
Dynamic Web Module 3.0
Java 1.7 (JDK 1.7_21)
Java Annotation Processing Support 5.0
JavaScript 1.0
JavaServer Faces 2.1
JSTL 1.2
Oracle WebLogic Web App Extensions 12.1.1
I am using Oracle WebLogic Server 12c 12.1.1 zip distribution for hosting the application.
For example, I have a UserBean Managed Bean of Session scope, that has 3 String fields
and the respective getters and setters.
I create a "test.jspx" file, and from the Palette -> Tags tab -> JSF HTML I drag a Form into
the new file so I can connect it to UserBean and generate a form to enter its details.
I select the "Generate a form tag and content from data" and in the Choose Bean dialog
there is none of my Beans.
What could be the problem?
Thanks in advance.
Edited by: 997841 on Apr 30, 2013 6:09 PM
I forgot to mention the Oracle WebLogic Web App Extensions version 12.1.1 and that also
for JSF 2.1 the "sub-directory" Faces Configuration below the project in Project Explorer is not
existent, as in projects created with earlier versions of JSF.

Yes, they are both listed under the WebLogic System Libraries.

Web project architecture question, mulitple .wars vs a single .war

I am in the early stage of architecting a web project.
At this point, I've came up with two solutions:
Multiple .wars
Each section would be it's own .war that would be built into an .ear. This would allow a multiple developers to work on the project and if a change would be made, then only the changed .war would need to be built.
However, then I would have mulitple copies of the same library for each .war, so that could slowly become a maintenance nightmare.
Also, I haven't figured out how to communicate between each .war - I don't believe I can cross container context?
Single .war
I wouldn't have to worry about multiple copies of the same library files. Nor would I have to worry about losing session data between applications since I would be running under one container.
But I am unsure of the best way to have more than one developer work on the project? It was suggested that I look at cruise-control at sourceforge.net - an automated build process - thus developers could check in their source code and a build would happen every xx minutes.
What is the best way to approach a project that is made up of multiple applications that need to be under one application suite?
Thanks,
--Todd

Hi,
I would recommend starting with the simple case which is using a single war file. You can use multiple wars, but it can add a bit of complexity and force you to learn a few advanced fetaures to get started. You can also share common libraries among multiple war files inside an ear file, and Java EE has mechanisms to allow that sharing (BluePrints has a document on adding libraries to Java apps at
https://bpcatalog.dev.java.net/nonav/enterprise/portableextensions/frames.html ) but it is does add a bit of complexity for you to learn initially.
A good rule of thumb is to start with one war file, and only split into other war files if really necessary. The most common style is one war file.

Newbie looking for maven-based web projects

I'm looking looking for maven-based web projects so I could learn how to orginize and configure code and configuration files respectively. Thx in advance.

Another very good place where to find information:

Netbeans - Enterprise project vs Web project

This may seem like a kind of lame question, but having stuck with Vim for many months, Netbeans is my first venture into a proper IDE, and I want to make sure I become very familiar with it.
Basically I was just wondering if someone could give me a more insightful breakdown of the differences between starting an Enterprise project within Netbeans, and starting a Web project. My understanding of an Enterprise project is that it is very much business-oriented, ie. relates to customer management, supply information, that sort of thing. But I really don't see the benefit in distinguishing such types of programs from general programs... in my eyes, it's like highlighting one particular category out of all the possible categories of software, for no apparent reason.

This may seem like a kind of lame question, but
having stuck with Vim for many months, Netbeans is my
first venture into a proper IDE, and I want to make
sure I become very familiar with it.More important than sticking with Vim is using the command shell, javac, java, and having a thorough understanding of how CLASSPATH works. Very good.
There are others besides NetBeans, of course. Eclipse is free and not too bad. I prefer IntelliJ to both, in spite of the price.
Basically I was just wondering if someone could give
me a more insightful breakdown of the differences
between starting an Enterprise project within
Netbeans, and starting a Web project. What do you mean by "enterprise"? Is that one that uses EJBs?
My
understanding of an Enterprise project is that it is
very much business-oriented, ie. relates to customer
management, supply information, that sort of thing.No, you can do all those things using web apps without using EJBs. Does that make them less "enterprise"? I say no.
But I really don't see the benefit in distinguishing
such types of programs from general programs... in my
eyes, it's like highlighting one particular category
out of all the possible categories of software, for
no apparent reason.I'll have to wait to hear your definition of "enterprise" before responding, but applications with and without EJBs are different. They certainly deploy differently - with EJBs use EAR files, without EJBs can get by with a WAR file. With EJEs required a Java EE container like Sun ONE, JBoss, Weblogic or Websphere. You can deploy a web app to all of those, or you can stick with a servlet/JSP engine like Tomcat.

Noob JSP + Servlet + EJB information for building J2EE simple web project.

I am new to Java. Covered basics and now jumping into making a simple web project. Project with functionality as below
1- CSS and Javascript use.
2- Managing user information (Add, Update, Delete, List)
3- Login form (Pass username, password and authenticate to create cookie)
4- Success/failure page.
That's what I want to make. I have lots of ASP.NET experience so its better to learn from making a project.
I need help like
1- Anyone know any open source web project from which I can learn to complete above tasks.
2- Any good latest J2EE 6 books to cover JSP, Servlts and EJB to make website.
3- Any video tutorials.
I am also looking around for the above information.
Thanks

Is it better approach to keep business logic in Beans instead of Servlet/JSP. Looked more robust and clean?Usually you should keep the business logic (i.e. code) away from JSPs. That's how things were done 10 years ago, now we know better. Servlets and JSP can be used together so that a servlet has the business logic and JSPs are just "dumb views".
EJBs will/can help you when you need to worry about transaction isolation.
Then there's the dozens of other Java frameworks used for web design (and other purposes).
And the learning curve is high because it's a huge chunk of different technologies. It'll take you months to get proficient, years to become good.
But if you just want to whip up some web pages quickly, look at JSP/JSTL and Servlets. That'll give you a clean, but basic approach.

Question on create web project wizard - Web Application version

Hello -
On step two of the wizard it asks you for a web application version. Choices:
Servlet 2.3\JSP 1.2 (J2EE 1.3)
Servlet 2.4\JSP 2.0 (J2EE 1.4)
Does the choice ONLY affect the choice of how the top of web.xml is generated?
i.e.,
<?xml version = '1.0' encoding = 'windows-1252'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee">
...vs
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
...Are there any other places where this choice causes some settings to be set?
(I ask because I am working with a workspace that was generated from the Create Application wizard. Choosing the "Web Application [JSF, ADF BC]" Application Template doesn't allow the user to choose the web app version...)
Thanks,

Hi Scott,
No, this choice only impacts the version of the Web Deployment Descriptor (web.xml).
When you create your workspace from the Create Application wizard by selecting the "Web Application [JSF, ADF BC]" template, we suppose that you work with a J2EE 1.4 application (the current version).
If for some reasons, you have to work with a J2EE 1.3 version, f.ex. because you have to use JSTL 1.0 (see "JSTL 1.0 in JSP 2.0 Pages" in http://blogs.oracle.com/Didier/2006/03/20#a10), then you should create your Web Project and select "Servlet 2.3\JSP 1.2 (J2EE 1.3)".
Later, you have the option to upgrade your Deployment Descriptor to Servlet 2.4\JSP 2.0 (option in the right-click menu on the web.xml).
Regards,
Didier

Eclipse web project using Glassfish 4.1 can not load some libraries in modules directory

We installed latest "Glassfish Tools for Luna" (updated on 2 October 2013) and created a new Eclipse dynamic web project using Glassfish 4.1. When try to annotate a class with "javax.enterprise.context.ApplicationScoped", it complains as "ApplicationScoped cannot be resolved to a type" although imported as "import javax.enterprise.context.ApplicationScoped".
Checking "glassfish-4.1/glassfish/modules/" directory and there is cdi-api.jar that contains ApplicationScoped class. But when checking from the project libraries in the eclipse, couldnt see such a jar.
My configuration:
Eclipse 4.4
Glassfish runtime java development kit : java 1.8.0_20
Project java development kit : java 1.8.0_20
Project compiler level : 1.8
Project facets : Dynamic web module 3.1, Java 1.8, Glassfish Web Extensions 4.0, Javascript 1.0
How to solve this issue?
Thanks.

There are 274 jars in the Glassfish 4.0 modules directory, whereas there are 282 jars in the Glassfish 4.1 modules directory. So it is not only cdi-api.jar. Moreover there are some libraries, the names of which have been changed.
Why not simply importing all libraries in the modules directory to Eclipse, like Tomcat plugin does for tomcat/lib directory? So when manually deploying a library(jar) to modules directory Eclipse will discover it automatically.
Thanks.
