Java Extensions Mechanism is not working

I'm using Java SE SDK 1.6 update 3 on Windows XP SP2.
I have a Java application which uses jar files from other providers. Copied those jar files to %JAVA_HOME%\jre\lib\ext directory to make these jar files search ables.
Also JAVA_HOME environment variable is set to the full path of Java SE SDK.
When try to run Java application an exception is thrown indicating that classes are not found.
What could be wrong?
Thanks in advance for your help.
Regards.

Java Extensions Mechanism is not working on Windows Vista

I have installed JDK 1.6 Update 2 on Windows Vista Ultimate. Additional jar files sucha as JDBC drivers, etc were copied to $JAVA_HOME/jre/lib/ext directory to make these packages visible without specify their locations in classpath environment variable.
This mechanism works fine on Linux and Windows XP, but in the case of Win Vista, classes aren't found. When try to run a class that has references to these packages, an exception is thrown indicating that those classes don't exist or weren't found.
I don't know if I'm missing something or if I'm doing anything wrong. If that's true, please let me know to fix it ASAP.
Thanks in advance for your help.

Java 7 Update 11 Not Working with Firefox

For me, the problems described in the thread "Java 7 Update 10 Not Working with Firefox? " Java 7 Update 10 Not Working with Firefox?
are continuing with Java 7 Update 11.
Windows 7 64 bit
Firefox 18
The problem is that "Java(TM) Platform" is missing from the plug-in list.
I've uninstalled Java 7 Update 11 and reinstalled Java Update 9 which correctly installs the plugin and restores Java functionality which was broken immediately upon installing both Java 10 & 11.

Expert Mode ViewObject: default 'query by example' mechanism does not work

In JDeveloper 11G 1.1.1
I have created an Expert Mode view object(VO) which I'm trying to filter in an ADF Swing Panel
The Panel contains a Swing Table created by dropping a VO data control on the panel as an ADF bound Swing Table.
TEST
Run the panel.
Set the Query Mode on (from the Database menu)
Enter a relevant view criterion
Execute the Query
TEST FAILS
Table is refreshed but it still displays the entire VO collection (non-filtered).
Repeating the same experiment with a default, entity object generated VO works as expected.
Question
Can the default 'query-by-example' mechanism as provided by the JUTestFrame and the JUNavigationBar be used with Expert Mode view Objects?
If yes are there any tricks to making this work?

Hello Frank;
Additional TEST RESULTS
In JDev11G
The default 'query by example mechanism' does not work if you create a new View Object using the <Select data source...> option <Read-only access through SQL query>.
However, IT DOES WORK if you create a new ViewObject selecting <Updatable access through entity objects> and in the Query step you select <Expert Mode>
Could you please check and confirm.
Thanks!

Java.util.ProperyPermission does not work for

Hi again!
I have some problems with a security.policy file. Its content is provided below:
grant{
//Alow the client to connect to any port above 1024
permission java.net.SocketPermission "*:1024-", "connect";
permission java.util.PropertyPermission "user.language", "read, write";
Unfortunately, the java.util.PropertyPermission does not work. I always get the following exception:
java.security.AccessControlException: access denied (java.util.PropertyPermission user.language write)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)

Is there any problem with the decleration of the premission? Any ideas?

Err, this may come as a shock, but it's because you changed the system clock.
The Timer class works out the absolute time when to next to do something, and when you change the system clock you break that time.
How much are you changing it by?

Java(TM) Update Registration not working anymore

Hello,

[SOLVED] libreoffice extension pdfimport do not work

I have installed the libreoffice-extension-pdfimport (3.3.2-2). But when I try to open a pdf file nothing happens (no error messages, just nothing). I have tried several pdf files (including ones produced by libreoffice itself). I remember that earlier version of this package did work. Is this package broken? Can anybody of this list use it? I would like to know before filling a bug report.
Update: After having updated my whole system, it works now

Hi,
thanks for help. After lunch I can see the tomcat HP now, the command
$ ss -lnp|grep
tcp LISTEN 0 100 :::8080 :::*
I edit the bashrc to point TOMCAT_JAVA_HOME to the java-sdk-8 - an older forum poster said he changed the bashrc to get sun java permanently. His error messages was caused because TOMCAT_JAVA_HOME pointed to openjdk.
So, my bashrc contains a line:
JAVA_HOME=/usr/lib/jvm/java-8-jdk
I tried according to archwiki on Java:
# archlinux-java status
Available Java environments:
java-8-jdk (default)
# archlinux-java set java-8-sdk
'/usr/lib/jvm/java-8-sdk' is not a valid Java environment path
I am confused ?!

Hi,
When I try to access web start demo applications it redirects me to download page. It is not working for both Firefox 3 and Konqueror. If I type form command line javaws it will start some policy editor, which I assume means that web start is working. Is there any way to fix this?

I have updated my iTunes to the newest version, 10-25 on a windows XP system. Now my java virtual machine is not working and I need it to run applet window. My Java is also newest version. What can I do to fix/repair my issue?

I need help with java on windowsXP after updating iTunes to the latest version. My java will not work and I get error message need java virtual machine to run applet window. Did not have this problem prior to the iTunes update.
Please help, Thanks

If your library was working on your computer and then popped up empty all of a sudden then this might be what you need...
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

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.

Java persistence: sequence generator not working in expected way.

Hi,
I just played around with java persistence api and found that sequence generator annotations for making new primary key value not working correctly in my code. following is part of my code related to this problem.
in entity class:
@SequenceGenerator(name="mySeq", sequenceName="MY_SEQ_IN_DB")
@Id
@GeneratedValue(strategy=SEQUENCE, generator="mySeq")
@Column(name = "UPLOAD_ID", nullable = false)
private Integer uploadId;
I have a sequence called MY_SEQ_IN_DB in my oracle 9i testing db. When I ran the code to save a new entity instance to database I found that the new upload id is not the one that should be created from the MY_SEQ_IN_DB sequence, while the sequence was not increased either. It's instead something starting from 97 (in my pc), and increased just like a sequence, but every time I reran my code the sequence restarted itself again beginning with 97(of course the insert failed with primary key conflict). the behavior just looks like it's a sequence created and managed totally by the persistence api or toplink itself (I guess).
So, my question is, is this a designed behavior or have I done something wrong to make it not using the correct sequence in the db?
I used hibernate before, and assigning new primary key from sequence in this way works fine.
Thanks

There are some things in Java which can't be serialized. When contained within a higher-level class such as Buttons. A button can be associated with an Action Listener. Now, you can serialize a button; however you can't serialize an action listener - for what should be to you obvious reasons. This is NOT an error and so there is no need to throw an exception when serializing the button.
Basically: Applet sends servlet button, but not listener.

New FocusTraversalPolicy Mechanism Does Not Work Well With OO Designs

I would like to complain about the new focus traversal mechanism not working well with object-oriented GUI designs.
Specifically, we have many reusable panel classes that can be swapped in and out of reusable dialog classes. On some of these panels, the default focus traversal is not what is desirable, perhaps because one component on the right side of the window is just slightly higher than a component on the left side, maybe due to the component on the right having a label on top, and so the default focus goes to the component on the right instead of the left. So we have a need to be able to explicitly define the order of components in some panels.
If I try to define a focus traversal policy in the panel's constructor, a NullPointerException is thrown because the panel's focus cycle root is null (the panel has not been added to any dialog or frame yet).
If I try to associate a focus traversal policy at the dialog level, it would have to explicitly reference its child panels' inner components, which would break the encapsulation of the panels. It would also make it hard to have generic dialog classes into which various reusable panel objects can be swapped.
Someone suggested making each panel a focus cycle root. This makes it hard to "break out" of one panel to move on to the next panel in the dialog. Special keys would have to be assigned to try to cycle out, and these keys would have to be different than the normal traversal keys, making them inconsistent and nonintuitive to the user. Also, the focus policy would have to know if the dialog had more than one panel, what order the panels were in to know whether to cycle to the next panel or not, etc. This is a mess.
Does anyone have any idea how to get around these problems? I have tried using a global focus policy with a global hash map of prev/next component key-value pairs, but we are still running into trouble with some deeply nested tabbed dialogs. It's just not possible to always have the focus cycle root in existence at the point where you want to explicitly define traversal between two components, or when you are trying to establish the default component for a panel in a tabbed pane.
Has anyone else run into similar issues?
Robbie Gilbert
[email protected]

I agree completely. One of the popular consultants on this forum stated that the new focus mechanism was more versatile and only a little more complex. I would say it's more than a little complex given the trouble average programmers are having understanding how it works...at least at first...and after understanding it realizing that they are going to have type their fingers off to update their code. Oh, and the dread of maintaining this awful mess.
I'm currently having the same problem as you Robbie. Some of my reusable panels need special tab ordering...that's not usually a problem, in most programming environments, till now. Now I have to go around the world and back just to get my stupid cursor to be in the right place when I hit the tab key??!!! and special key mappings just to get out of a focus cycle...lame.
And how is an IDE graphical designer going to work with this? It's not, that's how...ok maybe if some kind person or company creates a custom focus traversal policy editor of some kind, I don't know.
Good grief Sun! We need something to help us meet our deadlines, not solutions that force us to spend 80% of our time customizing every stinking bit of UI functionality we need!!!
JTables are even worse. I've mastered most of the garbage that is JTable after many months of pain and I don't know how I'm going to help my peers understand them in any short amount of time. Most of them were Oracle Forms programmers, not that that is any great solution either. But they will likely have problems.
In conclusion, I wish I had chosen another UI technology for our new product client, and may yet.

Java webstart proxy bypass not working

java webstart does not work through proxy as the jar files is not getting downloaded. most simple solution would of course be to bypass the proxy for the target server (by entering the server in the system network preference panel). however, that does not work. apparently this bypass is not taken into account by java webstart.
if i remember correctly there once was a possibility to set such things (proxy etc.) in java webstart preferences. this is not existing any more.
how can i solve the problem?

tobias (very desperate)

Hi,
Thanks a lot for your reply, Prateek.
I have already checked SAP Note 1142580 - "Java Proxy is not processing messages in parallel" where they ask to modify the ejb-jar.xml. However, on performing the change in ejb-jar.xml and while building the EAR, I get the following error:
Error! The state of the source cache is INCONSISTENT for at least one of the request DCs. The build might produce incorrect results.
Then, on going through the SAP Note 1142580 again, I realised that the SAP Note 1230721 also should be looked onto which will be needed for generating the Java proxy from Message Interfaces in IR for parallel processing.
Kindly help me if any of you have worked on such a scenario.
Thanks in advance,
Regards,
Rosie Sasidharan.

My java is installed but not working

My java is installed and it was working fine a couple of days ago but when i went to restart my computer my java had stop working. I checked to see if my enable java was checked in the security tab, and it is but it's still not working? Is something wrong with my Mac? since i had restarted my safari i'm thinking that was the issue.

Check if your bank has a app for the iPad. It sounds like you are trying to use the bank's web page/site rather than using an app.
