In the JAXB Tutorial, why...

...is comment a global element in the XML schema? It is a simple type based on xsd:string, yet is declared globally and "ref"erenced everywhere it is needed.

are you referring to same example explained in JAXB tutorial issue ( with simple JAXB unmarshelling example) . thread ?

In Java EE 7's Firstcup tutorial, why does does the web tier consume the data from the dukes-age web service?

In the Firstcup tutorial, the responsibilities of the web tier are listed as:
dynamically generate content for the client
collect input from the user
return results from business tier components
control the flow of client screens & pages
maintain session state
perform basic logic
hold data temporarily in JavaBeans components
Which of these responsibilities would retrieving data from a web service fall under?
The tutorial also lists the technologies used in the web tier, and JAX-RS is not included in that list. The list of technologies used by the business tier does, however, list JAX-RS. I was surprised to find the DukesBDay JavaBeans component (in the web tier) calling the dukes-age web service, instead of the DukesBirthdayBean EnterpriseBean (in the business tier), which uses hard coded value for Duke's birth date.
Is it typical for the web tier to consume web services in this way? What about when using an application client container, wouldn't that skip the web tier altogether, and in doing so also skip the web service call? Wouldn't DukesBirthdayBean in the business tier benefit from making the call to the web service, instead of having the date hard coded into it, and wouldn't this also solve the problem of the missing web service call when using an application client container?

Hi Shadab,
Here is a list of Web service standards supported by SAP in NetWeaver 7.1.1: [Supported Standards|http://help.sap.com/saphelp_nwpi711/helpdata/en/44/624479f7e608fae10000000a422035/frameset.htm] (also in [7.0|http://help.sap.com/saphelp_nw70/helpdata/EN/44/624479f7e608fae10000000a422035/frameset.htm] and [7.0.1|http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/44/624479f7e608fae10000000a422035/frameset.htm]). The Enterprise Services adhere to these standards, and on the provider side you have the tools to configure the authentication settings as needed. On the consumer side, one just has to use a Java release (or any other platform) that supports these standards.
While I am not a Java developer, there should be [many ways to consume a Web service in Java|http://www.google.bg/search?q=consumewebservice+java].
Hope this helps,
Rossen

The simplest thing - why it doesn't work?????

I develop a big application with lots of different panes containing all these controls...
I want the user to click a menu item and then the corresponding pane will appear, replacing completely in view any pane that appeard before that. I've tried everything - using JFrmae, JPane, JLayeredPane, rootpane, nothing seems to work perfectly .There's always a glitch and the previous pane somehow appears underneath under some circumstances.
I didn't find anything on that in the java tutorial or in the forums. I hope you guys could help me. Thanks in advance!

Thanks, that worked!
I now have all these different classes of panels that I can call from the frame class, but I can't call the frame class from any of the panes...
This is the error message that I get when I try to call a public method of the frame class from the pane class:

I want all three files to compiled successfully.If it is compiled only then I will continue on Unmarshalling process

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)

Is there a bug in the WebService tutorial for JDeveloper 9i?

In reading through the JDeveloper 9i tutorial for building a web service, the final step generates the DateTimeServiceStub.java, but the testing that follows does not use this class, it uses the DateTimeService class.
I built a Web Service based on the this tutorial and when I test with "MyClass.java" it works fine, but when I try to use "MyClassStub.java" it throws the ClassNotFound Exception below:
java.lang.NoClassDefFoundError: HTTPClient/ModuleException
 at mypackage.RandomQuoteStub.<init>(RandomQuoteStub.java:21)
 at mypackage.RandomQuoteServlet.doGet(RandomQuoteServlet.java:27)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:195)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:309)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:336)
If we are supposed to use the Stub methods, any thought as to why it fails?
If we are NOT supposed to use the Stub methods, any thought as to why they are generated.
(Yes, I am a bit new to Web Service development).
Thanks in advance for any answers,
RB

Hi Richard,
I ran into another problem when I tried to create a web service and call this web service following the tutorial from Oracle9i JDeveloper Release 2.

Problem with the firstcup tutorial

Hi, I'm a developer that is new to Java. I walked through the "firstcup" tutorial using the netbeans 6.5.1 ide and glassfish 2.1 server.
I thought I had successfuly completed all the code and xml config files.
When I got to p14.html, "Building, Packaging, Deploying, and Running the firstcup Enterprise Application", I run into a problem trying to run the tutorial app.
Posted below is the error I get in the webpage. The server log file error is too long to post because of the character limit of this forum.
If anybody could point me in the right direction I would appreciate it. Also if this question should be posted on a different forum please advise,
Thanks,
Paul

Paul,
What does the below diagnostic message mean to you?
java.lang.ClassNotFoundException: com.sun.firstcup.web.DukesBDayTell me, I'll confirm or repudiate... and then we'll looking to why that might be the case, leading to what to do about it.
<aside>
If you're new to Java then jumping straight into J2EE probably isn't the way to go... especially if you're totally new to programming, especially web-programming... The serverside EE-technology-stack builds on the core Java langauge and API's (J2SE)... and without at-least a basic understanding of the Java language itself I predict that you're going to really really struggle with the EE tutorials... and that therefore you'll probably give up in disgust.
They call this page [getting started|http://java.sun.com/docs/books/tutorial/getStarted/index.html]... I (for one) think it's aptly named... Nobody gets to skip HelloWorld, or the universe will implode, or something ;-)

Importing the Ravenna Tutorial Site

Hello, I was able to import the RVH Tutorial Site and everything went as planned, EXCEPT after it installs then I go and run the Indexer because the doc says that needs to be done before you can view the site in teh browser. Well I went in to the Repository Manager and Ran the "Collection Rebuild Cycle" it Finished and is now sitting idle. I now try to go to the site and I get page not found.
http://myserver/rvh
WHY? What am I missing?
I also went to the files where that folder exists and there is no index.htm like the doc says, I only see the follow:
sitenavigation.hda 22-Apr-2009 15:35 1.6K
sitenavigation.js 22-Apr-2009 15:35 9.4K

Life after the DiveLog tutorial

I have been learning java for a while now, I have studied sun's Java Tutorial and other similar sites. Then after getting a grasp of the basics I moved on to example applications, such as the DiveLog application. My question is 'where do I go from here'? I was wondering if any readers know of any online example application tutorials (similar to the DiveLog or maybe slight more advanced). I found this method of learning more beneficial, (showning the principles being put in action). I am particularly interested in seeing how a java project develops from design to implementation using as much theory as needed and putting it in a form that is interesting to read and practice. Any links to similar projects would be greatly appreciated.
Incidentally, I am aware the DiveLog tutorial is not yet complete (only up as far as part 4). So if the authors of the tutorial happen to read this article, it would be worth letting the readers know when the next parts will be posted.
The divelog tutorial has been an excellent tutorial to learn from. Its method of explaining concepts as they were being implemented in a real project provided a more interactive and interesting way of learning than simply explaining theory page by page like most. Hope to see the next parts soon! If there are other similar tutorials out there, in terms of the method of teaching, on whatever subjects of java, please let me know. Thanx for any help.

This may not be exactly what you are looking for, buy why not consider volunteering some time to help write java for a project that interests you?
I learned alot about java by volunteering to help write java code for an internet game. It was a fun way to learn, the people were very helpful with any questions I had, they also gave me space on their server, gave me software, etc....
If that sounds like something you want to look into, check out http://sourceforge.net/
Look over the list of current projects, maybe something will interest you.

I'm stuck! Following the Java Tutorial

I'm confused :=Q
I am following the Java tutorial and am trying to do the ClickMe applet. The html file was saved as text in notepad. I downloaded the ClickMe and Spot source files. They compiled without errors along with the html file. I double checked my DIR and saw that I had the class files. When I went to run the applet, the little window appeared without any spot and said something about Clickme class in the heading border and then in the box it said applet not initialized. So, I went through the forum and looked for anything similar and I saw that someone said to compile like:C:\jdk1.3.1_01 javac ClickMe.java Spot.java
So, I tried that, and I still have class files, but now I don't have the applet box showing anymore and I don't get any errors. I was successful when I did the Hello World applet, so I know it's not a class path problem or text prob. I was using typing appletviewer ClickMe.html
I'm getting so hungup on trying to get the applets to work I am losing track of how and why they are supposed to work. It is so discouraging especially when there doesn't seem to be anyone in particular to ask.
Does anyone have anything encouraging to offer?
I am using JDK 1.3 on WinXP (Java has been totally enabled without using the plug in) It has worked successfully.
Thanks in advance once again for your help.
Karen

I'm learning with the tutorial also ;)
Makes about 3 months I'm doing so, and from my experience, it is much more fun to create Programs than Applets.. I always work with Swing and it is a pain to use it inside Applets (but Swing is really great to create GUIs..) Learning how to build Jar and how to use Swing helps you building up Jar files that run like EXEs ;) That gives good results!

HT4997 I want to burn a movie to a dvd with iMovie but idvd doesn't show up in the "share" menu--why? My SuperDrive indicates that my DVD+R can be written to. Please Help.

I just spent a week creating an iMovie and wanted to burn it to a DVD. The instruction tutorial said to go to the "Share" menu and select "iDVD", however there is no "iDVD" listed in that memu. I checked to see that my DVD+R was writeable in my SuperDrive--it is? Why doesn't "idvd" show in the "share" menu? Please help, thank you. Fustrated Mark.

I may have found a way around this issue. I have the old style mouse with a wired usb connection. I've learned from other discussions that by holding down the 'Control' key and pressing the mouse button on an Apple a menu similar to the right-click menu of a PC will appear. When I tried this from the 'Project Library' on iMovie on my iMAC, a menu appears that DOES contain the export to iDVD choice. This choice is still not visible from the 'Share' menu in the menubar. This appears to be some glitch in the Apple software, but my computer is currently formulating the iMovie into the iDVD format. I have my fingers crossed.

How to print the Swing Tutorial

what's the best practise to print e.g. Creating a GUI With JFC/Swing tutorial ?
Are the Sun Java Tutorials available in PDF format also ?

opera02 wrote:

Or better still, create a build file that will stamp out the Java Tutorial as a Java Help document set. It is not only viewable, but easily searchable for keywords etc.
The only thing I can see that makes the tutorial in any way printable, is that it apparently has a print stylesheet attached that hides the links on the left of the the page.
Why kill more trees, over something that is better viewed using a browser or (the JavaHelp) HelpSet viewer?
Edit 1:
BTW - Welcome to the Sun forums.

Question about scope in the enum example in the Java Tutorial

Hi,
On page http://java.sun.com/docs/books/tutorial/java/javaOO/enum.html of the Java tutorial the enumeration MONDAY is not prefixed with the enum name when it is used in the function tellItLikeItIs.
public class EnumTest {
     Day day;
     public EnumTest(Day day) {
          this.day = day;
     public void tellItLikeItIs() {
          switch (day) {
               case MONDAY: System.out.println("Mondays are bad.");
                              break;
               case FRIDAY: System.out.println("Fridays are better.");
                              break;How does the compiler know that MONDAY is the same as Day.MONDAY? Is it because of
switch(day)Then later in the main MONDAY must be prefixed with Day. I removed Day. and it did not compile. Why is Day. necessary in main but not in tellItLikeItIs?
public static void main(String[] args) {
          EnumTest firstDay = new EnumTest(Day.MONDAY);
          firstDay.tellItLikeItIs();Thank you.

swtich is a special case.
The label for each 'case' of a switch
will infer based on the type of switch value
switch(d) {
case MONDAY:
case TUESDAY:
will automatically refer to the MONDAY and TUESDAY
corresponding to d's type.

In the year view, why is iCal coloring the boxes?

In the year view, why is iCal coloring the boxes and what does each color mean and how do we change it? It makes no sense or has any rhymn or reason according to what is in my calendar.

By default it is colored by the number of entries for each day. From white for no entries through yellow to orange and then red for the most entries.
Hope this helps.

I am trying to backup my Itunes onto my external hard drive. I am at the step where I on Itunes, click on File - Library - Organize library. I am suppose to check mark both boxes there, It won't allow me to check mark the second box, why? How to fix this.

I am trying to backup my Itunes onto my external hard drive. I am at the step where I on Itunes, click on File ->Library ->Organize library. I am suppose to check mark both boxes there, the first being "Consolidate Files" & the second being "Reorganize files in the folder 'Itunes Media'. I am able to checkmark the first box but It won't allow me to check mark the second box, why? How can i fix this? Please help!

Well you must have made a mistake somewhere. The last instruction of step four reads:
When you've found your iTunes library folder, drag that folder to your external hard drive. This will begin the iTunes backup. The amount of time the backup will take depends on the size of your library. When the transfer is done, your backup is complete and your external hard drive can be disconnected.
Normally dragging content from to a new location on a different drive will result in a copy action which is what you were supposed to do. At a guess you somehow managed to move the iTunes folder. Then when you started iTunes it created a new blank library for you assuming it had just been installed rather that raising a warning.
Close iTunes. Rename the iTunes folder on the internal drive as iTunes (Empty) then copy the iTunes folder from the external back into the User's Music folder. Start iTunes. All should be well.
When you've made sure it all works please read my User Tip and use that method to backup in future. Since you already have a folder with the backup in place you can skip the "Make New" operation in the fourth step and simply choose the external folder.
