Java BluePrints versus Jakarta

I created a new Visual Web Pack Application, for source structure I chose Jakarta (the other option is Java BluePrints), because I am going to deploy my application in Tomcat 5.5.17. For server I obviously chose Tomcat 5.5.17.
Also, I added the BluePrints AJAX components 0.1.1 to the component libraries of my project.
However when I wanted to drag an Auto Complete Text Field on one of my project's page this turned out to be impossible. I guess because I chose Jarkarta as source structure instead of Java BluePrints.
Does anyone know how to solve this problem?
What are the consequences of choosing Java BluePrints as source structure when you want to deploy in Tomcat?
Thanks,
Annet.

Well, the String.replaceAll(String, String) method uses the Java regexp internally, and I'm not sure there's a way to change that. So that at least is one place that will use it. I don't know for sure, but Jakarta's ORO is supposed to be fully compatible with Perl 5, and also supports other regexp types as well, so if you need that aspect of it, then go with Jakarta. I heard some of Java's are a little limited in some capabilities. I can't find any particular pages that refer to any comparisons of them at to compare runtime performance.

Java BluePrints AJAX Components in MyEclipse

Hi,
I wanted to know how to use Java BluePrints AJAX Components in MyEclipse IDE. I want to use Auto Complete Text Field in particular. Is it possible to use those components in MyEclipse? Any suggestion is appreciated.
Thanks.

I am unable to get the Blueprints AJAX Components it

Java Built-in regular expressions versus Jakarta

Are there any advantages to using the Jakarta regular expression package, over the built-in Java regular expressions?
I wasn't able to find much information on the Jakarta regexp package, except for the Javadoc and I didn't find that very informative.
Thanks!

Java Desktop versus Enterprise client

What is the difference between Java Desktop Application versus Enterprise Applciation client?

Desktop Applicatoin is local to your computer, it may have connections to the network, such as MS-Word will connect to the internet for updates and help files.
An Enterprise Application is developed on multiple tiers--local clients, web servers, data servers, and etc. Processing done in an enterprise Applicatoin is distributed amoungst the different tiers.

Java techlogies versus PHP

Hello,
we will have big web project. And now I must choise techlogies. All projects were create with PHP.
Now I think change technology, because I think PHP will small for this project. This project can have more that 1000 users one time. This site will have chat system, and users will often make requests.
Can I say, what Java will be better decision in this project?
Can you give examples where Java better in big projects?
I think about servlets and EJB.
I will be grateful for answers.

PHP or Java?
The basic difference between Java and PHP is that with Java you can have actual object model underneath - n-tier application. That comes handfull when you handle a lot of users and various datasources.
Another thing is that with use of object models like EJB or COM+, .NET you can use transaction framework already built into the system or object pooling (Here maybe I can mention connection pooling - in PHP I think each page opens its own connection (In java the same connection can be used by many clients)). I won't mention the separation od data and business logic in this level.
In general you also can test the whole application, which I'm not sure if you can with PHP.

Java technology versus VB

Hi,
I am deciding whether i should develop my next application using Java or VB. It will be like another version of MusicMatch but without all the fancy features. This application's primary task will be to send out a file, through a USB (or midi) port onto a device.
I am famaliar with both languages but obviously an amatuer. Does anyone have any suggestions or preference they can share with me?
Much Thanks,
Jimmy

"Being able to clicking on an icon to start the program, without needing to install a Java virtual machine first."
Well, if the program is written in .NET then they would need the .NET framework to run the application. But i see your point, is there anything besides the fact that it is a Microsoft OS for a program written in VB to RUN?
Ultimately, this application will cross over to the MAC platform. But if i told you that that wasn't my concern...It would be great to kill two birds with a single stone.
So if i told you that i only had to get this application done and done well in a Microsoft OS and let somebody else worry about the MAC said, would it be unanmious to say that VB WOULD WIN?
thanks

Compare Sun Blueprints vs Jakarta Struts

I currently use Sun Blueprints for my projects, following the Petstore application.
But I never use Struts.
So, I'd like to know what is the different between them?
Which is the mostly use in the market?

I would answer this question by asking another question. What is the difference between plain and spicy food?
The answer lies in the taste and some improvements to your palate. I can and am trying to realte the same to the Sun Blue Prints and Struts.
Sun Blue Prints are the base for developing and nurturing your applications using the best practices and industry standards being developed/suggested by the Gurus working at SUN.
Struts on the other hand is the next step to MVC architecture(another blue print from SUN) eveloved over time with some new features added to it to make the development easier with a differnt paradigm all together.
As for the question, what is used more in the industry, SUN blueprints are used invariably everywhere whether you use Struts or not. I have come across many companies and friends using Struts as the new framework for developing J2EE applications.
I guess this is the next step in evolution of J2EE applications. But all said and done, the business needs, budgets, time and resources are some of the factors to keep in mind before jumping on to the bandwagon of using struts for applications which can be developed easily and at a relatively lower cost by using plain Blue Prints from SUN without any gizmos on to it.
Hope i was able to answer some of the queries and concerns.
Thanks

Java dispose versus hiding

Hi,
I am working on a desktop application , where in I want to call a different Java Form class when a user presses a button. Details are as follows
2 classes
1.MainPage ( JForm Class)
2.Transaction Page (JForm Class)
Events :
1. Startup --> MainPage--> Initialize & Connect DB--> Show Menu etc.
2. MainPage.closeButton --> Trigger -->Create new Transaction Class --> dispose MainPage--> Show TransactionClass
3. TransactionClass.closeButton --> Trigger --> Create new MainPage Class--> Dispose itself--> Show Mainpage
I am using Netbeans for development and Derby as embedded database for a small application. My question is whether the process above is the preferred/suggested method to show & hide classes. Everytime I am disposing and creating MainPage it creates new conenction . Everything works perfectly fine without any glitches or issues, but I would like to know if there are any best practices when it comes to such scenarios. Please share your thoughts/experiences.

Thanks for suggestion. Any thoughts on whether it is advisable to keep the previous form in memory , whether it slows down anything or not ? Although my form is very light but just curious :)Again, just given what you've told us, if you are creating and discarding transaction pages, from a single main page, it is very unlikely you are going to have performance or memory issues (unless your transaction uses algorithms with exponential time/memory requirements).

Using the Model Facade Pattern in a Java EE 5 Web application

Hi,
Yutaka and I did a Tech tip
http://java.sun.com/mailers/techtips/enterprise/2006/TechTips_Nov06.html#2 on using a model facade pattern in Java EE 5 web-only applications recently. We got some questions about it, and these were some of the questions raised...
Question 1) the first part of the tech tip(it has two articles in it) http://java.sun.com/mailers/techtips/enterprise/2006/TechTips_Nov06.html showed how to access Java Persistence objects directly from a JSF managed bean, is this a good practice?
Question 2) when to use a facade(as mentioned in the second part of tech tip) ?
and maybe
Question 3) why doesn't the platform make this easier and provide the facade for you?
Briefly, I will take a shot at answering these three questions
Answer 1) You can access Java persistence directly from your managed beans, but as your application grows and you start to add more JSF managed beans or other web components(servlets, JSP pages etc) that also directly access Java Persistence objects, you will start to see that you are cutting/pasting similiar code to handle the transactions and to handle the Java Persistence EntityManager and other APIs in many places. So for larger applications, it is a good practice to introduce a model facade to centralize code and encapsulate teh details of the domain model management
Answer 2) IAs mentioned in answer 1, its good to use a model facade when your application starts to grow. For simple cases a spearate model facade class may not be needed and having managed beans do some of the work is a fast way to jumpstart you application development. But a facade can help keep the code clean and easier to maintain as the aplication grows.
Answer 3) First note that both of the articles in the tech tip were about pure web apps(not using any EJBs) and running on the Java EE5 platform. Yes it would be nice if a facility like this was made available for web-only applications(those not using EJBs). But for web-only applications you will need to use a hand-rolled facade as we outlined in the tech tip. The Java EE platform does provide a way to make implementing a facde easier though, and the solution for that is to use a Session Bean. This solution does require that you use ythe EJB container and have a Session Bean facade to access your Java Persistence objects and manage the transactions. The EJB Session Facade can do a lot of the work for you and you dont have to write code to manage the transactions or manage the EntityManager. This solution was not covered in this tech tip article but is covered in the Java BluePrints Solutions Catalog for Perssitence at
https://blueprints.dev.java.net/bpcatalog/ee5/persistence/facade.html in the section "Strategy 2: Using a Session Bean Facade" . Maybe we can cover that in a future tech tip.
Please ask anymore questions about the tech tip topic on this forum and we will try to answer.
hth,
Sean

Hi Sean,
I'm working on an implementation of the Model Facade pattern where you can possibly have many facades designed as services. Each service extends a basic POJO class which I'm calling CRUDService: its short code is provided below for your convenience.
The CRUDService class is meant to generalize CRUD operations regardless of the type of the object being used. So the service can be called as follows, for example:
Job flightAtt = new Job();
SERVICE.create(flightAtt);
Runway r = (Runway) SERVICE.read(Runway.class, 2);
Employee e = (Employee) SERVICE.read(Employee.class, 4);
SERVICE.update(e);
SERVICE.delete(r);SERVICE is a Singleton, the only instance of some service class extending CRUDService. Such a class will always include other methods encapsulating named queries, so the client won't need to know anything about the persistence layer.
Please notice that, in this scenario, DAOs aren't needed anymore as their role is now distributed among CRUDService and its subclasses.
My questions, then:
. Do you see any obvious pitfalls in what I've just described?
. Do you think traditional DAOs should still be used under JPA?
. It seems to me the Model Facade pattern isn't widely used because such a role can be fulfilled by frameworks like Spring... Would you agree?
Thanks so much,

Can't connect to Oracle XE instance from Java web application

I'm a long-time Java developer but can't figure this out.
I've been pouring over the forum for over a week and can't
find the solution that will let me connect.
Hardware: Intel/Vista.
DB: Oracle Express 10G.
Application: Java web application (Jakarta Struts)
Application Server: Tomcat 5.5
I copied the latest JDBC driver from OTN into my app server's "/LIB" directory.
I get no driver errors. ("ojdbc14.JAR)"
I can connect locally from my TOAD client, using SYSTEM/PASSWORD/XE.
My listeners seem to be OK.
Depending on which connection string I use from my Java application,
I get one of two messages.
"ORA-01017: invalid username/password; logon denied"
OR
"Io exception: The Network Adapter could not establish the connection"

Using the code you supplied I was able to reproduce your errors. I've adjusted it accordingly and can connect to one of my 10.2 test databases.

    // conn = ods.getConnection("scott", "tiger");
    ods.setURL("jdbc:oracle:thin:@localhost:1521:TEST");
    conn = ods.getConnection("scott", "tiger");
    Statement stmt = conn.createStatement();
    ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION");
    while (rset.next())
        System.out.println (rset.getString(1));   // Print col 1
    stmt.close();
}There are several different ways to configure OracleDataSources:

So, hopefully it's just a mismatch config.

Hi,
This could be one of those cases where using Java 7 versus Java 6 makes a difference, or perhaps there is some conflict with the JDBC driver version. So, a few things to try...
1. Make sure your installation's SetJavaHome line in ...\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf points to a Java 6 JDK.
2. If (1) does not work, also uncheck the Use OCI/Thick driver box in Tools -> Preferences -> Database -> Advanced.
3. If (1) and (2) do not work, also copy the ojdbc6.jar from any Oracle client you might have installed to your installation's ...\sqldeveloper\jdbc\lib directory
I would think doing just (1) should be sufficient. If on Mac OS, use sqldeveloper-Darwin.conf instead.
Hope this helps and please post back here and let us know, one way or the other,

How to use blueprints components in Exadel Studio

hi friends i am working in a JSF project with Ajax support. i need a JSF-Ajax calendar component.. In my project i am using JSF and Ajax4jsf. If i want to use blueprints calendar component in my project what i should do.... how to integrate this component in my project... how to work with blueprints in Eclipse Exadel Studio IDE.....
please tel me the step by step procedures to follow....

Hi,
the installer jar is a jar file that needs to be un-jarred, usually by double clicking the jar file. Once you (install) un-jar the
1) For example, if you download the latest solutions catalog from
https://blueprints.dev.java.net/servlets/ProjectDocumentList?folderID=4144&expandFolder=4144&folderID=0
you will download bpcatalog-ee5-ea-0.6-installer.jar
2) then you have to install/unjar it
To Install: Double-click the jar file bpcatalog-ee5-ea-0.6-installer.jar, or run 'java -jar bpcatalog-ee5-ea-0.6-installer.jar'
3)This creates a folder bpcatalog-ee5-ea-0.6/ which has the contents of the blueprints solutions catalog, including the JSF component libraries.
4) then if you want to use a JSF component library such as bp-ui-14.jar which contains the calendar component, then move/copy the bp-ui-14.jar to your application that you want to us it in.
Then you use it like any JSF component library (see the links I put on previous posting if need more detail on that)
I think the confusion you were having is that you were using the installation jar bpcatalog-1.0.1_01-installer.jar instead of the JSF component library bp-ui-14.jar in your app?
hth,
Sean
