IDE for EJB's

Hi there
I'm looking for IDE's for EJB development.
Best would be if it support UML notation or any other modeling language
if you know any, please let me now
thanks
Thomas

There are quite a few available, you can try Oracle's JDeveloper, you can
download it from oracle for free (evaluation), you can also try ArgoUML,
that you can get from www.sourceforge.net or www.freshmeat.com . It's an
opensource utility written in java that resamlbes Rational Rose. Hope that
helps.

Ideas for developing new Mini project

Hi All,
we want to develop our programming skill by doing some mini project in Java technology.
A group of 3 members want to involve in this project with IDE as JDeveloper. So anyone can suggest a mini project with some 10 days duration. We are strong in Swing-EJB. We also intersted to work in JSP,Java script. Also ready to learn new technology..
So whichever applicable suggest us or give some ideas for the project to improve our skills.
Note: we are one year experienced in java Programming.

Hi Lrj1985,
According to your description, in order to allow users to know the probability of collecting from a debtor dependent on different dimension, you nedd to produce an OLAP cube to perform this. Since you haven't done this for a few years, now what you
are looking for is that the ideas, starting points or direction to build the OLAP cube, right?
In this case, here are some links which describe how to build a cube step by step, please see:

Java IDE for Unix/Linux

Hi everybody
I'm switching to Red Hat Linux. Does anybody know any good IDE for that OS? I'm looking for something not too heavy, don't want to run massive IDE like JBuilder. For example under windows I use JCreator which is quite light, but unfortunately there isn't a Linux version.
Cheers mates

Since this is a J2EE forum, I would recommend NetBeans 4.1 which has excellent web tier (JSP/Servlet) support as well as EJB and Web Services support now.
http://www.netbeans.org/community/releases/41/index.html
There's also a bundle for NetBeans 4.1 + Sun AS 8 2004Q4 here:
http://java.sun.com/j2ee/1.4/download.html#nb (full J2EE 1.4 support).
IMO, Eclipse is not there with Web tier development and has no EJB/Web Services support.

Excessive cxs socket connections created for ejb access

We are seeing a large number of TCP connections being created to the cxs engine for ejb access in our application.
We are running iPlanet application server 6.0, sp3 on Solaris 8. We have a web application that accesses a singleton component running in a kjs engine. That singleton accesses cmp entity beans and stateless session beans for serving client requests over the RMI/IIOP bridge. When three clients are connected and making requests, the number of TCP connections to the IIOP port (9010) starts to increase until everything freezes. I believe the "freezing" of the client apps is due to the open socket limit of 1024 being exceeded. According to the developer doc we can increase rlim_fd_max to 8192 to fix that problem.
However, my question is why are there an increasing number of socket connections? We are caching the ejb instances in the singleton so we should not be creating a large pool of EJBs. I have verfied the large number of sockets using netstat and also using RMI runtime logging in the kjs engine.
Does anyone have any ideas what could be happening here?
Thanks,
Mark

I noticed that most of the TCP connections are made to port 32787. Can anyone from iPlanet tell me what is listening on this port? The large number of socket connections is really tying up server resources.
Thanks,
Mark

Options for EJB - Corba - correct?

Hi,
I'm looking at the options for EJB->CORBA and CORBA->EJB method calls in Weblogic Server 5.1 (although we may be moving to 6 soon)
We are currently using CORBA 2.1 C++ code, and are looking for a migration path into EJBs.
I've tried to pull together small list of our options, with apologies to Eduardo Ceballos who wrote most of this text originally, and anyone else who's work is included.
Does any one have the time to read the below, and make any comments on important options that I've missed, or pitfalls that they can see?
Thankyou in advance;
Notes:
-- RMI over IIOP is only available under JDK 1.3
-- if we use a pre Corba 2.3 implementation (as we currently are), only primitive types may be passed (no OBV available).
-- Another option is to use WebLogic Enterprise, but we are currently using WebLogic Server. ‘WebLogic Enterprise Connectivity gives you the ability to create IIOP connection pools to a BEA WebLogic Enterprise, allowing you to execute WebLogic Enterprise CORBA objects from WebLogic Server servlets and Enterprise JavaBeans.’
Calling from a WLS into a CORBA server:
========================================
There are several variations on two ways:
1. expose the CORBA interface;
To expose the CORBA interface, you collocate the ORB of your choice within the WLS instance and bind CORBA stubs into the JNDI tree as needed. The application looks up CORBA objects and uses the CORBA server interfaces as you would regardless of WLS.
This is an example of designing the RMI interface so that it maps in a usable way to the IDL interface.
2. hide the CORBA interface.
To hide the CORBA interface, create a RMI interface and a RMI server class; run 'weblogic.rmic -iiop -idl ...' on that class; take the resulting idl and add it to the interfaces which the CORBA servers implement. To gain access to the CORBA servers, use COSNaming to bind the CORBA servers into the WLS JNDI tree. As above, the application looks up the CORBA servers in the JNDI tree, but in this case the application uses the RMI-IIOP stubs to communicate with the CORBA servers.
This is an example of adding RMI interfaces to existing CORBA servers to establish some level of connectivity.
If you are using an RMI-IIOP implementation of some sort, then you are effectively hiding the CORBA interface, except you'd ignore any of work that would be done at the IDL level.
Note: We should use rmic and the –noValueTypes flag (as we aren’t using Orbix 2.3).
Calling from a Corba server into WLS
======================================
It is possible to host an Orb in the app server, contained within a WebLogic startup class. This will allow Corba calls to be delegated to app-server components (see option 1, above).
Thanks again.

Thankyou in advance;As far as I can tell, pre-2.3 ORBs can not handle type ids that start with "RMI:". So pretty much the only option at the moment with a pre-2.3 ORB is to delegate through a colocated ORB. As with the the previous response, it's a good idea to host the ORB in a WLS client, that way if the ORB goes south, it doesn't take the server with it.

Is there support for ejb local interface?

Hi,
Is there support for ejb local intefaces in JDev? By default it creates remote interfaces
& I have to manually edit the interfaces as well as the ejb-jar.xml files.
I am using JDev 9.0.2.
Thanks in advance...
Regards..
Dipankar

Right. The aforementioned -migrate flag on the jdev or jdevw command line will migrate the IDE settings from your previous build.
Other upgrade issues are handled automatically the first time you open a project and save it with the new version.

Need advise on selecting the IDE for swing UI development

Hi,
I'm looking for a best IDE for developing swing application.
Our application is a Rich Desktop Client Application which will have more than one hunderd screens. And all the business logics will be J2EE EJB services.
At the initial stage, we thought of using the .net winform technology as Desktop Rich GUI for its best look & feel and productivity perspective, by invoking the business services thru webservices.
But later, we decided to use swing components which are somewhat promising now-a-days. This will avoid the multi-platform issues, maintainability and perfomance difficulties.
I would be so much grateful, if somebody could share me their experience on deciding the IDE which would be the best for Swing development currently.
If any one has the list of different swing UI builder IDE and the feedback list correspondingly, could you post them?
..Thiruppathy.R

Thanks All!!
I experienced both NetBeans and Eclipse recently. I did not work in-depth in any of these IDEs for swing application. All the observations are from my first impression on them.
Please find the below are my feedback on both of these IDEs from my experience in the swing application development perspective :
Net Beans
Advantages:
1. Palette Manager option is good -> I can add the custom components to the palette very easily and make them available to use them readily.
2. IDE Layout / Framework is impressive -> In the swing design mode, the palette, properties, inspector and source all are evenly arranged in a way that things can be managed smoothly. It's very impressive.
3. Swing Components Alignment options are good -> IDE is very smart in arranging the swing components in the Panel or Frame. Even it helps the user by showing the alignment lines in the background. So we can definitely say that Net Beans has come in much better shape.
Disadvantages:
1. I am not allowed to change the generated code in the IDE.
2. I can't change the component name or event method name, other than the IDE generated one.
3. Additional Design codes will be reflected only at the runtime, but not at the design time. Here the developer is loosing the flexibility of using the code changes that impact the design.
Eclipse - Visual Editor
Advantages:
1. Source and Design mode, both can be viewed simultaneously.
2. Source and design, both are in sync all the time. The user have the complete control with the code.
3. As everyone knows, the IDE is very powerful and ease of use.
Disadvantages:
1. I can't add any custom components to the palette to make it available for ready use. Only option is 'Choose Bean' to add the custom components. So I should remember the component name everytime while adding in the panel / frame.
I also tried few commercial plugins with Eclipse. Given below is my feedback from my experience,
1. Eclipse - JFormDesigner
Advantage:
1. It provides Palette Manager option and very smart in the swing components alignment settings.
DisAdvantages:
1. For the design mode, it uses JFD file and later java code will be generated from this JFD file. So what you are seeing in the design mode is JFD file, not our java source. Developer have no option to see the source changes in the design mode.
2. It is a commercial product.
2. Eclipse -> Jigloo
Advantage:
1. Easy to use.
2. Custom swing components can be added the Palette.
Disadvantage:
1. It is similar to Eclipse - Visual Editor, but the difference is in the look and feel of the palette and event handlings.
2. For commercial purpose, you have to purchase it.
I also tried the JBuilder, but seems that it provides the Eclipse - Visual Editor for Swing Application development.
I didn't try the IntelliJ IDE yet, for swing application development. Some of the forum responses tells that IntelliJ IDE is very powerful, but not recommended for swing application development.
Eclipse - Visual Editor is promissing and it's open source. As I'm beginner to the swing development, I might have some short vision on some of the above said items.
If somebody have a better comparison sheet and could share with us, I would be grateful.

Replying to myself. Kept trying different areas of the ipod this evening, clicking various buttons, including some I'd never used before. All of a sudden I could see my Nano in iTunes. I quickly clicked on Restore before iTunes changed its mind about recognizing the iPod. Moved some songs onto it and it appears to be back to normal. Keeping my fingers crossed.

I've run diagnostics. Can't find device. I've tried resetting. The toggle has been turned on and off.

Cable works fine on my other iPod. Reset by pressing menu and center button together for 6-10 seconds. Left it to charge for many hours. Started acting up while running. Suddenly the music stopped playing but my Nike + was still working for the rest of my run. Took it straight it home and plugged it in to the wall to recharge since the battery was fairly low. Looked like it recharged ok but then screen went blank and now does it not show up on iTunes, does not seem to recharge by the wall charger (apple wall charger plugged into a surge protector in India). I have turned the hold switch off and on many times.
Sounds like a repair issue, which is not easy to do in India :(

Welcome to the Apple Community.
I have seen previous versions mentioned in a pop up message before on iCloud.com, but I'm not really sure at all how it would help, as I couldn't get it to do anything.
The best advice I have at this time is to back up your work on your iOS device by regularly saving it to iTunes, if anything goes wrong you can then either load it into the numbers app again on the device or recover it via iTunes on your computer.
My syncs are immediate, I never get chance to see if it works in the background, sorry.

Some calendars in iCal appear corrupted but OK on iPhone. If I sync will the calendar data on the phone restore info on the desktop iCal? any other ideas for how to sort this please?

Some calendars in iCal appear corrupted (ie have red exclamation mark by them) but are still OK on iPhone. If I sync, will the calendar data on the phone restore info on the desktop iCal or will I lose that as well? Or could I back up the calendars on my iPhone somewhere and then import them into iCal? any other ideas for how to sort this please? it's driving me mad. thanks.

Can you help me with Page Layout and/or Design ideas for a software manual?

Greetings,
I am a new InDesign user, and am converting a software manual that I created in MS Word into InDesign. It will be converted to a pdf to view online. I have the basics (3 master pages, page numbers, running headers, 2column pages with text boxes on the left and screenshots on the right), but I want to make it look prettier. Could you please give me some ideas on page layout and/or design to make it look better or more creative?
A few things that I am considering: borders around screenshots, a watermark, a logo next to the page numbers, different size/type of fonts, etc.
I am open to any suggestions to make this look better. However, please understand that I am new to InDesign. With that being said, please tell me a few steps when you mention your tips. Thank you!

Take a look at a few websites on Cannons of Page Construction.
I think the best idea for you is to look at a few software manuals and take tips from how they accomplished the layouts.
I'm not saying to copy them - but rather see what works and doesn't work, what worked for them might not necessarily work for you - research some layouts.
Fonts/type/sizes etc. are pretty much ambigious without context - is this a software manual for kids (soft cuddly big fonts easy to read), technical (small, tight spacing etc), Adult friendly (smooth, crisp clear, well spaced), elderly (large elegant fonts).
It all really depends on your demographic audience.
Being new to InDesign I suggest you take up Sandy Cohens Quickstart Visual Guide.
I think you should look at Michael Murphys Book on Styles
And you should definitely get your printer (the guys bulk printing) the booklet for you on board from the start to work out optimal sizes to suit their printing presses and workflow etc. And to ensure that you are setup correctly in page sizes, margins, safe type areas, colour profiles and a few other things that your printers prepress can help you with.

Ideas For A Text-Based Game

I tried working on Graphics a while ago, but I didn't have too much luck with that ;)
Just wondering if anyone here has any ideas about a 'fun' text-based game, that wouldn't be really based on RPG style stuff, because I don't really want to bother with having characters save and stuff(I kno how to though...)
Something like Rock/Paper/Siscors(spelling? lol), but kinda more adicting...oh right, forgot to tell you...idea for a MULTIPLAYER text-based game ;)
Thanks
-Been trying to think of a good idea all day, no luck ;)

Think of an existing exciting game, and make a clone. Thinking of new games is hard.
Scissors.
