Please recommend Java development package..?

Hi all,
I'm new here, and would like your recommendation on a development package. Currently I write all my Java in a UNIX editor, and "println" is my debugger. ;-)
I want to "upgrade" to a nice graphical editor w/ drag-n-drop, lots of good online documentation and an excellent debugger. Probably will go w/ Windows, but maybe Linux. I'm not doing servlets or applets or anything like that - just applications w/ basic Swing, w/ vast amounts of file/socket I/O and data crunching.
Would greatly appreciate your recommendations for a moderately-priced package, like maybe JBuilder Pro?
Many thanks, -tm

I have gown quite fond of the Eclipse IDE and it is supported on Linux, WIndows platforms. Oh, and its free. Choose the v2.0 Stable build (beta) from www.eclipse.org.
Or, look into Forte for Java Community Edition (also free). It is quite good, but I have found it unusable on remote X terminals due to Swing whereas Eclipse still performs quite well on both local and remote X terms.
Many folks I know on Unix and Windows platforms live life quite well with their favorite editor (xemacs, vi, TextPad, whatever) and JDB. Many live with no debugger and I too have had to get by that way as well. It works for me too.

Javadoc after Mac OS X 10.6 Java Update 3 and Java Developer Package

I can't seem to find javadocs, src, nor any real documentation on my Mac after installing Mac OS X 10.6 Java Update 3 and the Java Developer Package. NetBeans used to just find it, and now doing a find as shown below reveals nothing. Does the Developer Package actually include docs anymore? If so, where do I find them?
find /System/Library/Frameworks/JavaVM.framework/ -name "doc*"
find /System/Library/Frameworks/JavaVM.framework/ -name "src*"
find /System/Library/Java/ -name "doc*"
None of these turn up anything.
Thanks!

It took me a while but I solved it like this:
In NetBeans, open the Java Platform Manager (Tools -> Java Platforms).
Click the Add Platform... button in the lower left corner.
Select Java Standard Edition (selected by default).
In the File field, enter: /Library/Java/JavaVirtualMachines/1.6.0_22-b04-307.jdk/Contents/Home
Click Next >
The Platform Sources field should say: /Library/Java/JavaVirtualMachines/1.6.0_22-b04-307.jdk/Contents/Home/src.jar
If the Platform Javadoc field is empty, browse to or enter: /Library/Java/JavaVirtualMachines/1.6.0_22-b04-307.jdk/Contents/Home/docs.jar
Click Finish
Exit NetBeans.
Open: /Applications/NetBeans/NetBeans 6.8.app/Contents/Resources/NetBeans/etc/netbeans.conf (e.g. in TextEdit)
Beneath the line that says: #netbeans_jdkhome="/path/to/jdk"
Enter: netbeansjdkhome="/Library/Java/JavaVirtualMachines/1.6.022-b04-307.jdk/Contents/Home"
Overriding the default location in the netbeans.conf file may be enough such that you don't need to add the platform in the Netbeans Java Platform Manager.

Not really. It is just one of the few decent books I've seen. If you are a true beginner, I suggest a computer science program at your local college or university.

Java Development issue/differences between Core Duo and Core 2 Duo (??)

Hi Everyone,
I am a Java developer that uses my 17" MBP Core Duo for all of my development. Lately, I've been trying to use both the Glassfish Application Server V2 (from Sun) and Maven 2.09 from the Apache project. I have configured identical scenarios on my MBP Core Duo and on a 15" MBP Core 2 Duo.
The scenario involves compiling and running some webservices (at least on the Core 2 Duo) in a local development environment. Both machines use the default JDK 1.5.0_13 installed on the machine.
On the 17" Core Duo, issuing a "mvn install" command produces the following error:

I have installed the same software versions and have the same configuration on a Windows desktop running XP SP2 and get the same successful result.
Is this an issue between the Core Duo and Core 2 Duo? I can't see that it is since I don't believe the hardware influences the software to that degree. However, I am at a loss for what is causing the issue and the Apache Maven list insists that there are developers that are using Maven successfully on OS X.
I really need to get past this issue, but I am at a loss. Please help.
Thanks,
John

Issue with create user and issue with Java Development tab

I have two issues with EP,
1. When i login with Super Admin user, i am unable to Create any user from User Admin tab. Do i have to change the settings of the Super Admin? or is there any criteria for creating the user?
2. How to assign any user the Java Development tab. Though i login with a super admin user i am unable to see the Java Development role and when tried to assign the role, there were no searches for that Java....

Hi Adi,
by default the super administrater has got all permissions. Thus you should be able to create portal users when using a user assigned to the portal group Administrators.
In order to help you with your first question we need more information. Please describe the malfunction in detail. Have a look into the log files and post related error messages.
Regarding your second question: You will find the java development role in PCD
pcd:portal_content/com.sap.pct/platform_add_ons/com.sap.pct.pdk/Roles/com.sap.pct.pdk.JavaDeveloper.
If not, then you haven't installed the PDK business package in your portal.
Go to service.sap.com, choose downloads and search the package (PDK should do it). Download the package, and deploy on your portal using SDM.
Best regards,
Martin

Java Developer Exam.

I'm thinking of taking the Java Developer exam.
People who have done the Java Developer exam, could you please contribute with your help by answering these questions ?
1. How long did you program in Java before taking the exam on ?
2. How long did it take for you to complete the programming task ?
3. Was it more difficult than the Java Programmer exam ?
4. Is it worth to take it ?
5. What was the hardest part of the exam ?
Other comments on the Java Developer exam are welcomed as well.
Cheers
/Andreas

Here is what I would recommend, based on my experience:
* Take the mock exams - the tests at javacertificate.com do a good job of helping you identify your strengths and weaknesses. Dan Chisholm's mock exams are tough, but also good for opening your eyes to some things you might not have thought about.
* Concentrate on your weaknesses (mine were assertions, garbage collections, and threads).
* Practice your butt off writing code. Practice, practice, practice. And DON'T use an IDE. Code with a simple text editor and compile from the command line. The test is going to tax your ability to "compile" in your head and you don't want an IDE doing that work for you.
* Familiarize yourself with the Exam objectives. Know those inside and out, and you'll have no trouble with the test. Don't waste time on non-covered topics (e.g. java.io, java.awt).
* Figure out why you want this certification. It's not going to win you any admirers among the gurus. It's probably not going to get you a job. It doesn't mean you can code your way out of a wet paper bag. It's just the start of your journey in Java.
For me, it was something I wanted to prove to myself - a self-taught, entry-level programmer at the time - I could get. It helped me tremendously in my understanding of basic Java, so I don't regret obtaining the cert one bit. I also realize I have a LONG way to go. So, good luck, study hard, practice, practice, practice, and let us know how you do! If I can be of any help, let me know. :o)

Development Package migration

Hi,
I know I've two many threads for today. But, it's really urgent.
I have a question.
We've made a development package on the ABAP Workbench under the SAP R/3.
Then later we installed a new ERP ECC 6.0 system.
Unfortunately, when we migrated the hole package to the new system. It says that our package it's no originally made in this system and we could only update the package with some strange funktions like update and delete and whatever.
My question would it be, what should I do to make the package seems like it has been done on the new system?
-> The only solution that I could find that I must do it manually and this's gone take ages.
Unfortunately, I must do it manually because we have a namespace now and everything should contain the namespace. It's the worstest thing that I had ever expected.
How could SAP didn't think about that or am I really underqualified, considere that I'm only a student and am writing too much because it made me out of me when I lose too many time doing nothing.
I really excuse my bad english but when someone speak over four languages, he lose(the reality) the simple things that everyone knows i.e. orthographe and syntax.
Thinks anyway,
Best Regards,
Kais Kara

Which Java API's must a Expert Java Developer know thoroughly ?

There are more than 3000 classes in Java how can Java Developer remember or be aware of most
of them if he wants to become a Core Java Expert. Concepts like Object Orientation, Java Programming Syntax, Operators, Flow Control, Exceptions,
Assertions, String Formatting/Parsing, Collections and Generics, Inner Classes, Threading should be
basic and needs to be known by all Java Programmers.
But when it comes to remembering / awareness about 3000 or so Java classes how can a Java Developer
know all of them. As on job its not possible that one will come in touch with all of Java's classes
its only a limited section that generally one works depening on his domain.
Please share list of packages that are important or one should be aware of ?
What must be the approach/methodology/process to remember these Java API's ?

java.lang.Swapnil wrote:
Please share list of packages that are important or one should be aware of ?It's more important you know how to quickly work out how to use a class, by perhaps reading the javadocs, or, more often, simply from the name of it, and the methods it provides. That's a knack you get from experience and practice. The other side of that coin is to be able to write classes and methods such that other developers can get using them quickly, by looking at the names.
What must be the approach/methodology/process to remember these Java API's ?Use them a lot. There's no other way.

Newly released BOEXI31 Java Developer Guide available

I've been slogging along with the OLD BOEXI3x Java Developer Guide documentation which incorrectly references various security and principal classes.
However, I've just noticed this morning that a NEWER version of the DG is available at:
http://help.sap.com/businessobject/product_guides/boexir31/en/boesdk_java_dg_12_en.zip
which DOES reference the correct packages in the examples and scenarios.
...in case anyone shared my confusion.

Thanks for posting!
If you find any further doc bugs, please post in the forums, and I'll be able to forward the info.

Need Info Regarding Implementaion of Interfaces in java.sql package

Hi All,
I am interested in knowing details abt how the Interfaces in the java.sql package are implemented. We all work with the database using the interfaces provided ,but how do they work at the backend ? How can a Interface provide details (work ) with out an implementation class.I Is this taken care by the JVM or some of the Call level interfaces? Please do provide details abt this..

hi Sheshadri,
The implementation of the various interfaces in
java.sql package are provided by your jdbc driver,
which also manages the connection and communication of
your java program with the appropriate database.

RSPOR_SETUP = Different ABAP and Java support packages.

Hi all,
We have an ECC 6.0 system with abap+java stacks. When we run the RSPOR_SETUP report we get this error:
Different ABAP and Java support packages. Combination of support packages invalid
And with some more clicking we find this:
6. Compare version information of Java support package (com.sap.ip.bi classes) with ABAP support package (SAP BI)
   ABAP Support Package:                  13
   Java Support Package:                   0
On the Java stack we see (among others) these components:
sap.com       BI-IBC       7.00 SP12 (1000.7.00.12.0.20070509050058)
sap.com       BI_MMR       7.00 SP12 (1000.7.00.12.0.20070507084106)
sap.com       BI_UDI       7.00 SP12 (1000.7.00.12.0.20070507084125)
sap.com       BI-BASE-S       7.00 SP12 (1000.7.00.12.11.20080324092518)

sap.com       BI-REPPLAN       7.00 SP12 (1000.7.00.12.3.20080104101916)
So I believe all components are correctly installed.
What are we doing wrong?

Hello.
Please be aware, that report RSPOR_SETUP should NOT be used with a Netweaver 04s system. This report has been replaced by the support desk tool. I request you to run the support desk tool as per note 937697 to check if there are any configuration issues in your system.You can resolve any red traffic lights that might be reported by the tool by following the corresponding actions suggested.
I hope I can be helpful.

Flex for Java Developer?

I am working on flex 1.5 from last 7 months.Ealier i hv
worked on Java (1.5 Yr)
I hv created an application in flex sucessfully.
My Qtn is:
Whether i have to continue with flex or move to another
technologies like Struts etc.
Because i have nil knowlwge of FLASH.
or
I hv to start learning FLASH MX. Is it necessary for
Flex/Java Developer.
I am comfortable with action script if uses for Business
Application but
unable to produce better designs using it.
Please Suggest.
with Regards
Vinay

well vinay if u r thinking about -- Flex Front End to Your
Struts Applications
then ,,
Struts is an open source framework that facilitates the
development of web applications based on Java servlets and other
related technologies. Because it provides a solution to many of the
common problems developers face when building these applications,
Struts has been widely adopted in a large variety of development
efforts, from small projects to large-scale enterprise
applications.
Although Struts greatly facilitates the task of developers,
it doesn't do much to improve the end-user experience: the
end-result is still an application delivered in HTML and using the
traditional HTTP request/response mechanism.
Developers—and organizations in general—are
increasingly looking for solutions to provide their applications
with a more engaging user experience that overcomes the limitations
of HTML.
Macromedia Flex is a presentation server that addresses this
requirement and allows developers to build a new generation of Rich
Internet Applications (RIAs) that combine the usability of desktop
applications with the reach of traditional web applications.

Problem Installing Java Servlets Package

I downloaded a sample servlet program which imports classes from the Java Servlets Package. I have the JDK 1.2 which does not come with the servlet classes (javax.servlet and javax.servlet.http). So I then downloaded them from java.sun.com. They come as a set of class files in .zip format. I thought packages were supposed to be in .jar format? At any rate, my compiler still fails to see these classes even after I have extracted these files into the same directory as the original .zip file and added this directory to my classpath. Am I going about this the wrong way? Any ideas on how I can make my compiler see these classes? --Thanks

I down loaded j2sdk 1.4 . and also down loade servlet package. I installed in bin directory.
i took the sample program and compiled. there is error message " java servlet package not found.
please help. email me at [email protected]
Thanks
