HT5559 JAVA problems!

Hi, I might have installed Java 7 on my Mac OS 10.6.8 before I finding out that it is incompatible with Mac OS 10.6.8. I therefore need to make sure I am using Java 6. I found this page very usefull for what I need to do. BUT: after I copy-paste the first command line in Terminal, it asks me for my administrator password but does not take in any typing or copy-pasting. It only allows me to abort (ctrl+C) or hit enter!! I find myself obliged to restart my computer again and again and getting stuck at the same point.
Any suggestions?
Thanks,
D

When Terminal asks for your password, type it in and hit return. The password is not displayed.

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.

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.

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:

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

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.

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

Thank You for you help

Can anyone tell me about sites that offer free Java Problems and Excercises,Whats wrong with this site. Spend time answering questions here.
Read and learn from the postings of others who make suggestions and post solutions.
That way you learn while helping someone else at the same time.

Help please.

Hey Eli,
It looks like a memory issue. It would be good if you could provide more lines from db2diag.log file.
Please make sure that DB2 configuration complies with the default suggested. Below link would help you understand better.
http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp?topic=/com.ibm.db2.luw.qb.server.doc/doc/t0008238.html
More over set the ulimit for virtual memory and maximum memory size to unlimited in order to maximize the use of your current physical memory, after that restart DB2.
Please let us know if issue gets resolved.
Cheers!!!

Cannot access Yahoo Kids/indicates Java problem/but Java is installed

problems playing yahoo games/indicates java problem/java is installed and enabled but cannot get game to come up.

With details provided I am not sure what problem you are facing.
Here is generic advise on troubleshooting strategy.
Please provide basic details:
1) OS version and architecture
2) browser's you are tried (and their versions)
3) JRE version you have installed (for each architecture)
Assuming you have Java 7 update 7 installed (latest what java.com offers) please report
4) what version is reported on
http://www.java.com/en/download/installed.jsp?detect=jre
5) Can you run some other sample applets?
E.g. http://rintintin.colorado.edu/~epperson/Java/TicTacToe.html
Check java troubleshooting guide for tips:
http://docs.oracle.com/javase/7/docs/webnotes/tsg/TSG-Desktop/html/plugin.html#gcexdf
Specifically start with enabling full tracing details and java console. Do you see it popping when you try to start your target application?
Are there any errors? (If you do not see console then it may be exiting too soon - check if trace file is created in the trace folder).

Safari and Java Problem

Hi,
I'm having a problem with the newest updates to Safari. This problem did not occur until late december when I installed several updates via Software Update.
Problem:
I use a photo uploader on a website from my company (unfortunately I can't give out the URL, as it is protected). But it is similar to many other photo uploader sites - load a Java applet, drag images files into a Java window, the files are added to a upload list and then uploaded.
Now, if I drag 10 items into the window, only one or two will be added to the list. If I drag them in one at a time, all the images will be added. Previously it was possible to drag as many as one wanted in.
Now the really irritating part : During the upload, the Java uploader completely hijacks Safari. The window the uploader allways stays active on top. If I open a new tab or window the uploader window will reappear on top and dominate the action. The only way to get anything done while I am uploading photos is to open another browser like Firefox. Safari is completely occupied with the Java program.
Computer: MBP 2.16 GHz, 2GB RAM, OSX 10.4.11
Safari 3.0.4
Java 5.0 (not sure of the revision, but it is the most recent)
Any help would be greatly appreciated.

I had similar Java problems with Safari and Firefox. I downloaded Navigator and now can run any Java app I need. One thing that may or may not have had any impact: when installing Nav, it asked if I wanted to import settings from Safari or Firefox. I chose not to import any settings. Works perfectly.

HT5559 Java SE 6 cannot be activated again..

rr
The Apple support article HT5559 is easy to follow and clear, tried, but it just does not work.
Javaws still starts the JDK 7
(which can be checked using jvisualvm)
For our customers it is a big problem due to a bug in Java7 on OSX.
Right now i tried to start different javaws files (e.g. /System/Library/Java/Support/Deploy.bundle/Contents/MacOS/javaws OR /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/javaws )
with no success..
e.g. As brute force test renaming the folder /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/ should cause no harm (it is Oracle's JDK7, right..) but it stops javaws functioning. Therefore some reference still points to it (after HT5559). Why, which?
So we would be happy to figure out how to re-activate JDK6 on OSX.
Thanks in advance for any idea!!
Best regards
Tamas (=Thomas)

Check out the Java for Mac FAQs. You might have to uninstall the JDK first. Between it and the Apple doc, you should be able to sort things out.

HT5682 April 22, just installed the latest update to fix the Java problem, it does not work.

About a week ago I installed a MAC update. I discovered that I was unable to play POGO games. I know that is not up there with all other uses of MAC... let's get back on track here. I have uninstalled and reinstalled, and reset preferences at least 6 times to get JAVA back.
Some of my new BFF sites:

My Intel MAC circa 2009, is running MAC OS X Lion 10.7.5 Safari 6.0.4
Today I received another update from Apple stating it would provide the answer to POGO 6 and you can select certain sites that can be accessed.
This also was a FAIL!
I now know the steps, can access TERMINAL without shaking, have learned to use GO to access UTILITIES. I still end up with JAVA not recognizing that their software has a place in my heart and I truly hope on my computer soon.
I have been playing a horrible game of Solitaire on another site.
Are there others out there with this problem or is it just me? Can anyone suggest anything else?

Thank you BDAua. This is what I typed and the reply from Terminal
java -version

Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01-451, mixed mode)
BTW - this application does NOT show up in the Applications folder and I consider that a bit odd.
I also tried typing Java for my computer to search for and this is what I got under

I hope something is helpful within all of this info!
