First Cup of Java problems

Hi, i've been trying to learn Java2, I bought a book-Java2 a beginners guide, and that is how I found this site, they told me to download the JDK, I've ended up with j2sdk 1.4.0 it is located c:\j2sdk1.4.0 I've tried the first cup of java tutorial, and am having problems, when compiling-javac HelloWorldApp.java I get 'bad command or filename' so then I enter C:\j2sdk1.4.0\bin\javac HelloWorldApp.java and then I'm told that the program has performed an illegal operation and am kicked out. I tried to update the path variable, but don't seem to have any luck there either, some help or suggestions would be appreciated, I'm sure I can learn this stuff, at least I hope I can!!!!!
:)Ang

Does it say command not found?If it does, try changing directory to c:\j2sdk1.4.0\bin and agan typing javac and this time it should tell you the basic options for running javac.<<Doesn't say command not found, says 'Bad command or filename', then I tried c:\j2sdk1.4.0\bin and I get 'bad command or filename' again.......then I tried c:\j2sdk1.4.0\bin\javac and I get 'this program has performed an illegal operation' and am booted out...Is there some sort of setting that needs to be changed? I'm using windows 98. Thankyou for your help. Ang

J2EE 5.0 questions esp. re: "First Cup of Java"

Ok So I downloaded the latest "First Cup of Java".
I have Win XP Home. (Not professional).
I can't seem to find J2EE 5.0
I see SDK 5.0, and I have Net Beans 5.0. I downloaded the J2EE SDK, not the whole package. (B/C i don't have xp pro).
Can anyone help me re: this? I can't use the @ headers b/c supposedly i dont have EE 5.0.
-a little confused.

You don't need EE. That's the Enterprise Edition. It's for doing more advanced, complex things than you'll be ready for for a while.
J2SE 5.0 SDK is what you want--should be spelled out in the "First Cup" stuff.
When you say you "can't use the @ headers," can you be more specifc? Paste in the exact code you created and what you did to compile it, and exactly what error message you got.
When you post code, please use[code] and [/code] tags as described in Formatting tips on the message entry page. It makes it much easier to read.
Does First Cup use NetBeans? I thought it use the command line. Follow its instructions exactly. Don't even try to use NetBeans yet.

First two examples of "my first cup of Java"

I could compile and run the first example "HelloWorldApp" with the JDK 1.5.0 Version from the java-sun pages. And I could compile and run the second but only with the appletviewer. But my problem is, that I couldn't start the Hello.html file in my browser. I have Windows XP running on a board with a 1,30 MHz AMD Duron Processor. And I have a Microsoft browser with the Version 6.026. Anyone can help?

Check these "help" items from http://www.java.com
If they don't resolve the problem, there are quite a few more helps and FAQs at that Sun site, do some looking around., and use the site search.

First Cup Problem

Hi Guys,
I'm moving to a J2EE team soon so thought I would give myself a bit of a headstart by taking the first cup tutorial. I downloaded the Netbeans 6.8 IDE with Glassfish 3 on my mac, which will use Safari as the browser.
I've followed all the steps and got the final part, But when I deploy I get a blank page in my browser, it seems to understand the title bar as that displays correctly. But all of the content within the form is totally ignored.
Below is a copy of my greeting.xhtml:-

It seems to me that Safari is having trouble with the xhtml I am serving? Any ideas on how to combat this issue or anything I have done incorrectly? Although there are no errors on build, just the xhtml code doesn't display
Thanks in advance,

...As for the suggestion to ditch NetBeans and use Ant, I mean really, why don't we just ditch the high level
languages and go back to machine code and command lines.well if you're going to professionally work with Java EE, you may eventually have to reconsider that attitude. Thing is, sometimes there's simply no other choice but using command line tools. I mean, in commercial development not in toy projects from tutorials.
Oh and sticking with IDE can certainly lower chances to get an answer at forums like these. Just think of it...
Hello I am using Netlipse IDE version 6.6.6. I have Habracadabra setting selected in Mumbo-Jumbo config dialog...Do you expect reader to install your version of your IDE and learn about your settings - just to answer your question?
Now, read another question (like yours) from another guy (like you)...
...using Ecbeans IDE version 7.7.7 with Humpty-Dumpty setting selected in Ooby-Dooby config dialog...Would you (yes, you) install his version of his IDE and learn about his settings - just to answer his question?

JTable displays string in wrong order : my code problem or Java problem ?

I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
It would display it as : [Snowboarding[123456789
For a string like : "Chasing toddlers"+"<123456789>"
It would display it as : <Chasing toddlers<123456789
It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
Is there anything wrong with my code ? Or is this a Java problem ?

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* 
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* 
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* 
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* 
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

How/where can i find "user" entity from first cup tutorial in the database

within the first cup java ee tutorial a user entity is crated:
@Entity
public class FirstcupUser implements Serializable { ...in some other code the user is created and inserted?:
@PersistenceContext
private EntityManager em;
FirstcupUser user = new FirstcupUser(date);
em.persist(user);the question is how or where in the database(i don't know the database name, the table name should be user?) i can find the inserted users? within net beans in "services" i can see a db server with a "sample" database - this seems to be a preinstalled example db. but where can i find the db created by the web app i wrote?
thx in advance

Can't run DukesAgeResource examples (Your First Cup)

Hello, I believe I have found a possible issue in the "Your First Cup: An Introduction to the JavaTM EE Platform", and wonder if it relates to the fact that I cannot manage to run the example. At page 21, step 12, is states "In the REST Resources Configuration dialog, uncheck Add Jersey Library and click OK.". However, after clicking Finish (Step 11) no such a dialog is displayed, instead, NetBeans shows the DukesAgeResource.java file right away. Once I have completed entering the example and try to run it, I get this error message on the browser
HTTP Status 404 -
type Status report
message
descriptionThe requested resource () is not available.
GlassFish Server Open Source Edition 3.1.2.2
I deleted my project and files and tried again half a dozen times, with the same result.
I am starting out with Java EE, any clue about what I may be doing wrong? May be the issue is related to the discrepancy on the "Your First Cup" tutorial?
Note that the ready-made example that comes packaged with NetBeans runs fine.

Get a good book and begin by understanding it all, not by learning "what code to write".

Please help me with two Java problems

Hello,
I have 2 Java problems to work on and wondered if someone can help please?
1. I've created an array, but I have to now create a text file and write a program to read the array from the file. I have no idea where to start the program!
2.public class SumExample1 {
/* To determine if a number lies between 1 and 1000
* @param args the command line arguments
public static void main(String[] args) {
int num;
System.out.print("Enter a number: ");
num = TextIO.getInt();
if ((num >=1) && (num<=1000))
System.out.println("OK");
else
System.out.println ("Not OK");
Ive used a GUI to create some fields and buttons to press. How can I make it perform this little program?
Many thanks,
K

I recommend you read the tutorials on basic (file) IO and Swing (and Event Listeners if you want to make your GUI alive). Perhaps have a look at the Scanner class and BufferedInputStream. That should give you enough to start and write the program yourself. Try working in the command prompt first, should be easier, then once the logic works wrap it in a Swing GUI.
You can find the tutorials here:
http://download.oracle.com/javase/tutorial/
Swing:

Basic IO:

Hope this helps.

Java problems-locking

i have 10.6 and the latest download of java. I am trying to run Scottrader Streaming quotes and it locks up constantly/ Tech support suggest it is a java problem and i have a bad instalition of jave which i do not understand as software update installed it for me. the problem is that the java application will suddenly stop running/ any ideas? scottrade suffested reinstalling java. ig that is needed how do i unstall java?

If Java functions at all, then it is not apt to be an issue with the Java installation. There's really no such thing as a "bad installation of Java". Java will run or it will crash. Lock-ups are generally the result of application errors or communication errors (e.g., it's waiting on a responsed from a server that never comes).
You can reinstall Java using Pacifist and your restore DVD. I doubt that it will be worth your time, however.

Error Code 16 on Mac with Newly-Installed Yosemite (a Java problem?)

Like many out there I am unable to use CS6 applications at all after an OS update to Yosemite (in my case from 10.8.5, on my 2012 iMac). I get an Error 16 message, and a Java problem error message.
I've read many posts about fixing this issue, including the Adobe gospel very specific to this problem—about changing the permissions in a couple of folders—, which I found here: https://helpx.adobe.com/x-productkb/policy-pricing/configuration-error-cs5.html I did exactly as directed and saw no change in the problem.
I also read that the Java version necessary for CS6 products to run on Yosemite is a boondoggle in itself. Java 6 is apparently necessary for CS6 products to run, but that version is insecure, and besides, it's old. Java 8 Build 31 is the current and safe version but it apparently is incompatible with none but the most recently-updated Adobe products. Several posts on Adobe's support pages suggest a hacky fix for this Java issue, which involves downloading and installing the latest Java version from Oracle, and then creating specifically-named empty folders on one's hard drive within a couple of obscure System/Library/Java folders:
http://oliverdowling.com.au/2014/03/28/java-se-8-on-mac-os-x/
https://forums.adobe.com/message/7193884
I did this too, and again saw no change in the problem.
Re-installing my CS6 suite has not worked, either. I receive the same error code message when starting up any of the applications. At this point I've been forced to go back to my previous operating system, since I am heavily reliant on CS6 to do my work each day.
I understand that many people are having this trouble after updating to Yosemite, and more than a few posts on these forums indicate this is true even for people like me who've followed Adobe's purported fix that I linked above. Has anyone in userland or at Adobe found anything lately that could help here?

uninstall cs6 and clean (Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6).
update your os, Java for OS X 2014-001
then install cs6.

Installing 9.2.0.4.0 on EL4 - Can't start netca, JAVA problem!!!!

Dear all,
Please help with my Java problem. Thanks in advance.
After successfully installed Oracle 9.2.0.4.0 on EL4, I tried to start netca but I received this error message:
[oracle@localhost bin]$ ./netca: line 138: /u01/app/oracle/product/9.2.0.4.0/JRE/bin/jre: No such file or directory
The JRE link at $ORACLE_HOME is as follows:
lrwxrwxrwx 1 oracle oinstall 21 Oct 27 17:41 JRE -> /usr/java/jre1.6.0_03
.bash_profile as follows:
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/9.2.0.4.0; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=$ORACLE_HOME/bin:$PATH; export PATH

CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib; export CLASSPATH
LD_ASSUME_KERNEL=2.6.9; export LD_ASSUME_KERNEL
What do you guys think my problem is?

I managed to solve this one. For more information you can search the forum with much earlier dates, as far as 2002. I'm very outdated.
In case you need the solution:
I tried using java 1.3.1 provided together with the Oracle9iR2 installation Disks instead of 1.1.8.
1. Delete the JRE link in $ORACLE_HOME
2. Relink it to 1.3.1 directory
3. create a jre symbolic link in the bin directory to the .java_wrapper
4. create another jre symbolic link in the i386/nativethreads directory to the java file
Good luck

We have basically the same issue when we try to create the interpreter using the embedded method..
I was able to use the interpreter embedded in a java client as long as the weblogic jars were located in a weblogic install if I tried to use them from a maven repository no luck at all...
All of this worked easily in 9.2 now in 10.3 it seems more error prone and less documented.
I have seen close to a 100 posts on issues related to this so is there a document which outlines specifics....
We / I have used weblogic now for almost 10 years and moving from 8.1 to 9.2 was painful and we expected the move from 9.2 to 10.3 not to be soo bad but its proving to be as painful if not more painful than moving to 9.2. We seem to spend a good bit of our time working around issues in the next new release that were not in the previous one..
Any help would be appreciated I think we will open a support case but even that is more painful...
Any help would be greatly appreciated..
PS: We confirmed that all jars in the startweblogic classpath were in the startup. The server we have the embedded wlst instance is a managed server and we are using the component in a war... Are there any restrictions which we are unaware of.
Error we get is
1 [ERROR] com.tfn.autex.order.weblogic.QueueMaintenanceUtility.addQueue():217 Error Adding Queue wowsers JNDI Name wowsers Exception: Invocation Target exception while getting the WLSTOffLineScript path
