VB versus JAVA

Being new to JAVA, it seems a bit overwhelming especially coming from a COBOL background.
What are the advantages of JAVA over VB and vice-versa. I hear VB is easier to learn, but can it run on a webpage ?..What is more marketable or are they both the same as far as that is concerned ?
I guess I am still in that mode to learn a new language, but don't want to get overwhelmed by a new language, I am mainly looking for a language where it can connect with a database easily.
Thanks for your input.

Boy, this is the stuff that religous wars are made of...
Java: true object-orientation. platform-independence.
VB: Microsoft's imprimateur. tight integration with Microsoft products and OSes.
VB might be easier for you to learn, if you've never seen object-oriented programming before, but then again, it's a whole lot easier to program bad habits and crutches in VB.
Both are marketable skills. Both have database connectivity (Java has JDBC, and a number of adapters. VB has ODBC, DAO, and the whole alphabet soup of Microsoft DB connection technologies.)

Java 1.2 Versus Java 1.4?

This may sound quite strange, but I have a java program which uses Runtime.getRuntime().exec(...) and runs a perl process. The thing is when I run it using java 1.4.1 on a Solaris 9 platform, the perl script fails. However, if I use java 1.2 on Solaris 9 platform, the perl script works fine. However, java 1.2 is much older so I'm hestitant to use it.
What differences are there in java 1.2 versus 1.4 with regards to the Runtime.getRuntime exec???

Unfortunately this stupid perl script isn't that
easy. It uses Rational cqperl, then some libraries
and modules I don't understand. I can't even find
the actual code it uses that uses flexlm.
That's why I was asking what is different with java
1.2 and java 1.4. Is there some way that Runtime
acts differently?Not in any fundamental way that I am aware of.
The fact that the script is running at all though tells me that the problem is on the PERL side of things. I suspect that some of those modules and libraries are not being loaded correctly or the same way on both systems.
I fear the answer is that you need to figure out what components the script needs to run and make sure that it has them under all circumstances. This is like a classpath problem except it is with your PERL script so you need to solve it as a PERL problem.
Again if it wasn't running at all that would be one concern but it is running just not finding all it's bits.. a problem of that nature strongly indicates that the issue is happening once the process has already been spawned (correctly) and so is out of the realm of the Java part of your program.

Visual Studio 6 versus Java Advantages?

Hi,
I am very new on Java and SWING. Can anyone tell me what (if any) advantages to switching from GUI developement with Visual C++ Version 6.0 OR .NET Studio to rewriting the project in JAVA SWING.
I know that 1 disadvantage would be the slowness from the Java VM.
The advantage would be JAVA SWING can handle 256 color binary image display (Correct?) as opposed to
the (8 bit grainy picture bitmap of Visual Studio 6)
If anyone can provide some feedback, that would be great.
Thanks for reading,
Rage

comicrage,
Actually only you can identify the real advantages or disadvantages to rewrite a project and use certain tools. I can offer you my opinions based on my experience, and since you asked, here they are:
I have not experienced this "slowness" from the Java VM that everyone seems to be going on about. There is a pause to start when the VM starts up, but then there is in VB or .Net also.
I find the ability to move a project from machine to machine and OS to OS with out rewrite, tinking the code, or recompiling very very refreshing. I've done entire projects on Windows only to find they are implemented in part or their entirety on Linix or other NON-Windows product. I also like being able to update the VM without loosing the intended look, rewriting code, teaking code, or recompiling my project.
I cannot explain in words the satisfaction that it gives me to see my code be boring: sitting on the client, server, or middle tier and just running, unobtrusivly, on a 24 X 7 basis; never complaining, dying, or acting out... just doing what I intended it to do--yes, even when there are OS updates and new 3rd party vendor packages installed, it still is well minded.
I enjoy the product not bleeding the resources out and me not having to do a militant GC effort in my code to achieve that.
I enjoy connecting and being able to carry out my entire transaction without err, but on the occasion that something does happen, the ability to easily and gracefully recover and reinitiate.
Well, these are my thoughts... I program in C/C++, VB, C#, Java, ASP, JSP, and .Net.
My parting comment would be though, if you do not use Java, don't waste your time in MS version 6.x (unless you have to maintain old windows boxes--95, 98, etc), hit .Net heavily, it is here to stay for the good or bad.
... Oh, but then that is another thing I enjoy about Java: it runs on all those old environments too.

Possibilities Web Dynpro for ABAP versus JAVA

Hello,
I would like to know whether WebDynpro for ABAP and Java have the same options, abilities and possibilities. e'm I able to produce the same results with WebDynpro for ABAP as Java. I would like to standardize on just one of the two and be sure that it will to limit me later.
Thanks in advance.

Hi Maurice,
If you make have to make a choice you have to consider the followings:
- Which release do you have? Java version is available since 6.30/6.40, the ABAP only as of 7.00.
- Performance. If you have your WD4ABAP and backend (eg ERP) in the same system you gain a lot of performance
- Other small difference, that Java version has a much nicer graphical editor, which I miss from the ABAP version
These are, which came to my mind.
Best regards,
Peter

DB procedure validation versus JAVA method validation

Hi ,
We have an application that is developed with Oracle Forms as well as Java (ADF )
Now since ADF is the newer application, it was told to reduce the development time but provide efficient code. Now with Forms each field validation called a procedure and returned an error.
For example if Name is validated, They have a procedure VALIDATE_NAME proc. Why they have separated this is cause based on different customers and different products, the name validation differs. So the in parameters are Field val, Product, customertype... etc. Like this, there are 20 VALIDATE_FIELD procedures for respective fields.
Now to reduce duplication, I can call each procedure on each field. but that would means 20 DB additional calls for each procedure. If I write this logic in java it means I increase development time and probably increase probability of error.
Which is the best practice for VALIDATION.

Hi,
you already mentioned the pros and cons of the approaches. I don't think that it is good practice to directly call the PLSQL validation from Java as it means you wont be able to change it easily in the future. I would look for an abstraction layer that initially (for the time being) accesses the database for validation (maybe caching some validation policies upon application instance start) and later then can be changed to use pure Java validation rules. One thing coming to my mind would be something like a rules engine that reads the validation conditions from the database and that is accessed from Java. If your manager says you should reduce development time then my impression is that the choice is not yours and you will have to use the database (though it feels wrong).

Java 2013-004 versus Java 7 from Oracle

Back when Apple annoucned it would no longer update Java, I followed suggestions to install Java directly from Oracle. (Not sure of the version then, but the installation is now current on version 7.x running on OS X 10.7.5.) However, software update continues to offer updates for Java from Apple, most recently Java 2013-004. Why? What should be done about this?

So it's fine to have them both installed?
Yes. They do different things.
Can you provide any links that go into this distinction further?

Can't publish java xml stored procedure

I have written a java class to return values from the database as XML using the XSU, and am attempting to publish the class as a stored procedure. I have successfully created other java stored procedures, but am continually getting the following error on this one:
ORA-29531: no method getItems in class foo/bar/Inbox
To illustrate the interface which I am trying to implement, snippets from the java class and the Oracle package follow:
===========================================
Java class:
package foo.bar;
import oracle.sql.CLOB;
import other.stuff;
public class Inbox {
public static void getItems(int userID,
CLOB[] xml)
===========================================
Oracle package spec:
PROCEDURE getItems(user_id IN PLS_INTEGER,
buf IN OUT NOCOPY CLOB);
Package body:
PROCEDURE getItems(user_id IN PLS_INTEGER,
buf IN OUT NOCOPY CLOB)
AS LANGUAGE JAVA NAME
'foo.bar.Inbox.getItems(java.lang.Integer,
oracle.sql.CLOB[])';
===========================================
I originally structured the class to return the CLOB, but altered the structure to handle the CLOB as an IN OUT parameter so that the NOCOPY option modifier could be used, as suggested in S. Muench's book. I was surprised to hear that Oracle creates an in-memory copy of the return value from a function (wish I'd known this before).
All suggestions appreciated.
null

When I use JDeveloper's automatic Java Stored Procedure publishing feature, I get a PL/SQL spec that looks like this:
CREATE OR REPLACE PACKAGE EXPERIMENTALWORK
AUTHID CURRENT_USER AS
PROCEDURE GETITEMS ("userID" IN NUMBER,
"xml" IN OUT CLOB)
AS LANGUAGE JAVA
NAME 'foo.bar.Inbox.getItems(int, oracle.sql.CLOB[])';
END EXPERIMENTALWORK;You still have to add the NOCOPY by hand, but perhaps the int versus java.lang.Integer is significant?

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,

Compare Java based reporting to OBIEE

Hello All,
Due to a lot of misconceptions, my current client thinks that a lot of their problems will be resolved by simply retiring OBIEE and write all the reports in Java.
Some requirements are unrealistic to ask from OBIEE and some are well...limitations.
The client has asked us to give him reasons why he still should be on OBIEE. Has anyone done a comparison of Java based reports and OBIEE (or any BI tool)?
Reasons why OBIEE stands out would also help.
Thanks all!!

There are many, many reasons why to use OBIEE. One of the bigger reasons being you don't need to know anything about Java in order to build an Answer Report.
I've been asked a similar question in the past, to compare OBIEE versus Java based ADF. My response is that they have two completely different purposes.
--OBIEE is end-user/middle-user driven dashboards and ad-hoc analysis.
--Java/ADF is for power-users to pre-constructed reporting systems. (forgive me but I don't know the ad-hoc capabilities of Java/ADF)
If your client has full-time java resources to commit to the creation and maintenance of a Java environment, then by all means they should probably go that route. But keep in mind that as new uses want to see different data layouts and different data sets, your java team will quickly become overburdened.
OBIEE relieves the strain on the java (IT) team and allows end-users to drive reporting with the relatively occasional support by IT.
Yes, OBIEE does have limitations, but always keep in mind that a) It's an ad-hoc Dashboard framework and not an ad-hoc java framework which has much greater flexibility but requires much more technical expertise b) There is a major release of OBIEE (11g) just around the corner that is about to change the game in terms of how OBIEE can be used. You should have your client stay on board until they can at least see the new features.
Good luck and if you found this post useful, please award points!
Best regards,

Capabilities of Java

I am curious about the capabilities of Java in several areas.
1) I worked for a company that used Powerbuilder 10 and all they needed was an internet connection for the programmers to program off of a main server, nothing was connected locally. Is a team environment like that possible with Java?
2) The end application was also downloaded from the internet, so essentially you could program the application and use the application from anywhere in the world as long as you have an internet connection. It wasn't browser based either, an actual application. Is this possible with Java?
3) VB has VBA Script to use functions in Excel. Does Java has anything like this? for OpenOffice? Is it being developed?
4) I've heard Java is a pain to connect to databases. Why? Which database does it have the best interconnectivity with? How good is Java with MySQL?
5) PHP works very well with MySQL. What is the difference between the inteconnectivity between PHP and MySQL versus Java and MySQL?
I appreciate any commentary anybody con provide.

ajmasx: I really appreciate the information in a
professional manner.
Aknibbs: I googled quite a bit in an honest attempt
to answer my questions. I also asked my programming
professor, who teaches VB and Java, about the
functionality of Java. He knows a lot about how to
teach programming but little about its
functionality.Fair enough, most people don't put any effort into finding solutions and expect them handed to them. Based on the fact that you have brand new account, and that most people don't do any work, I play the numbers.
>
I think my biggest question is more about how to
obtain the functionality where I can be on any
computer in the world and be able to access the end
application. I think this might have something to do
with web services but everything I've read, it seems
to be a different technology. (I don't want to query
specifics from amazon.com to my website for example)
If someone knows how this is possible, can you
provide me a link of explanation or explain it to
me?
I'd love for anyone to give me help without insulting
my intelligence or implying I'm lazy.I never meant to insult your intelligence, or imply lazy, simply ensuring you had done (to me ) the most obvious choice for finding information.
I'm slightly confused by what you are trying to do now. Are you trying to get access to code for the application or get access to the application itself ?
If it is the application here are just a small sampling of things that you will have to decide:
1) Does your application require complex graphics (ie will it work over dialup )
2) Do you need a secure line to the application ?
3) How are you going to give control to it (such as haivng a remote machine take over the host)
If you could clarify further what you are trying to do I'll see if I can provide any more information.

If you can do it with C++ why not doing it in Java?

C++ is a great language but I dream of doing flex development
with java instead of actionScript simply because it is a superior
language (than actionScript). The bad side would be that it would
kill the JavaFX project.
I feel actionScript is oriented toward graphists and animator
and miss some business/serious features like generics, abstraction,
comprehensive collection library and thread synchronization.
C++ does have all of these. I don't what to enter a C++
versus Java flame war but I just would like to point out that there
is a need for a Flash VM that runs Java classes.

What is the difference between jsp :include and server side include

what is the difference between jsp :include and server side include(request dispatcher include method)????
i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
do suggest if u hav ny other diff in this context...

The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

I need a nice menu on a web page

Reusable Component Packaging

I have successfully packaged a number of custom component 'widgets' in a jar. Some of my widgets are implemented as composite components, and others are implemented as full fledged Java components.
My problem is that I get repeated errors in my server log similar to *'WARNING: JSF1064: Unable to find or serve resource, jcal.xhtml, from library, comps.'* when a using page includes a Java component.
The using page renders and acts correctly, it's just the server log message that's an issue. JSF seems to attempt to find the widget using the composite-library-name before seeing (and using)the tag declaration.
I would like to use the same namespace for all my widgets, regardless of their implementation. Perhaps I can't?
Mojarra 2.0.4 (FCS b09) deployed in war's WEB-INF/lib to Tomcat 6.0.20 under Java 1.6.0_05
Following is a snippet of my jar's taglib:
<facelet-taglib .... version="2.0">
     <namespace>http://dev.jimo.org/jimo</namespace>
     <composite-library-name>comps</composite-library-name>
     <tag>
          <tag-name>jcal</tag-name>
          <component>
     <component-type>jimo.HtmlJCal<;/component-type>
          </component>
     </tag>
</facelet-taglib>
Any pointers would be appreciated.
Thanks,
Jim

That is your own problem that you choose to do that. If you can deal with honest, direct and sometimes intentionally harsh replies, you'll get plenty of use out of these forums.
I did look through the first 8 or 10 pages of Google hits. All the java.net urls were dead links, the rest were specific to either servers (glassfish/JBoss) or implementations(Ice/Prime/Rich faces), and of those that I dug into, seemed related to css/js resources that were packaging problems or relative URL issues. The java.net links seem to be functional this morning, so I will go through them.Okay. The next time you make a post, be sure to note what you have already tried. Let me put it more plainly: don't post a question for which reading minds / crystal ball reading is required to get all the details.
Like I said, everything is working, it's just the log warnings that my component consumers are eventually going to be reporting to me...Unfortunately, sometimes warnings are logged when they shouldn't be, usually on the wrong log level (warn in stead of trace for example). Often I have seen messages being logged that were kind of "TODO" reminders to the devs of the API in question :/ The only 'solution' is to filter them out.
>
It's my first foray into component packaging, so It's quite possible that I'm breaking a rule or missing a config somewhere, so perhaps I should rephrase my question...
When developing JSF2 widgets for deployment in a jar, do seperate namespaces have to be defined for Facelet composite versus Java code implemented components?I can't answer that unfortunately, my knowledge of JSF 2 does not extend into custom widgets yet. The only thing I can advise is to grab a copy of the JSF 2 cookbook (of course, make your boss pay ;) ); it contains articles and examples for everything that JSF 2.0 provides, which includes custom JSF2 widgets (chapter 5). Then you can compare your work with what is documented there.

JDK 1.3 better than 1.1? Help me prove it!!!

i need any case studies done where a company upgraded their software from 1.1 to 1.3 and why it was better ? Can anyone help ?

What kind of application(s) do you have? For the server side, we have seen remarkable improvements in performance and SMP scalability (add more CPU's get more performance) in 1.3.1 than in 1.1.7. We replaced 10 Sun 4500's with 10 CPU's each running NetDynamics on a Java 1.1.7 platform with WebLogic 3 Sun 4500's with 10 CPU's each running WebLogic Server 6.0 on a Java 1.3.1 platform. We even saw a significant improvement in performance between 1.3.0 and 1.3.1 (about 10%).
Of course more than one variable changed between NetD w/ 1.1.7 and WLS w/1.3.1, but our other benchmarks have show 1.3.1 to substantially outperform 1.1.7 (3X or more for server-like benchmarks).
For an example of Java 1.3 versus Java 1.4 performance boost see http://java.sun.com/j2se/1.4/performance.guide.html.
If you are on Windows or IBM platforms, you should also look at the IBM Java 1.3.x JVM's as they tend to out-perform Sun's JVM's in many circumstances.
Why would you stay on Java 1.1? Is there come concern or need that prevents you from upgrading? Are you concerned about applet compatibility in internet applications?
