Problem with Java after Software Update to 10.5.7

Hi,
I am facing problem with Java after having run Software upgrades.
Here is the whole story. I recently moved to iMac 10.5.6 from PowerPc 10.4. On this new machine I was having problem running a 3rd party application, which requires JVM. As this application worked well on Tiger, I decided to upgrade JVM on my iMAC using Software Upgrade(was I insane!!). As I like my systems to be updated (as with linux on my personal machine) I clicked "install all". As a result I have the following upgrades run on my machine:
2009-05-20 13:12:01 +0200: Installed "Mac OS X Update Combined" (10.5.7)
2009-05-20 13:12:10 +0200: Installed "Remote Desktop Client Update" (3.2.2)

Hi man,
In the wake of this java problem I resorted to keep working on my old machine, and today in my spare time I tried to fix this new machine.
So I execute $java on prompt, and then try to check the files it has opened, using lsof -p pid
I see it referring to
/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java
isn't this usually the JAVA_HOME
However, executing $/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java
hangs!!
but
$/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java
works!!
$ pwd
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin
$ ./java -version
java version "1.6.0_07"

Linking my Current and CurrentJDK to 1.6 and it works!
However, shall that be the reason!
what is in your /Versions/Current/
I got the following
$ ls /System/Library/Frameworks/JavaVM.framework/Versions/Current
CodeResources Frameworks JavaVM

There is no /Home in here, which is usually the case for /1.5 or /1.6
Anyways, things seems to work for the moment. Lets see if I get problem with using Java.
thanks

Hi were you able to resolve yours?
I was very worried losing all my medical stuff on my iPad Air 2, plus i have nothing to use for the next day! So i have to try all the possible things i read on the internet!! And this worked on my part (Thank God, and thank you Google)
Perform a hard reboot
Hold down the Home button and Power button on your iPhone or iPad and keep holding them until you see the Apple logo. Once you do, you can let go. When your device boots back up, go ahead and check to see if the apps have started re-downloading. If they still appear to be stuck, continue on.

Problems with Mail after upgrading to 10.9.1

I am running into problems with Mail after installing 10.9.1. I had NO problems with Mail prior to this update.
Problems I have encountered so far are:
- I don't receive some e-mails on my Gmail account.
- I have sent e-mails that supposedly got "sent" but do not show up in my Sent box both on mail and on web Gmail. My Outbox is empty also.
Has anyone encountered the same problems and found a solution?
Thanks in advance!

Yes Paul I have, but no solution. I cannot send email. My ISP uses a smtp mail server for sending and It will not log in. Have had ISP on phone and checked all settings. Can only put it down to Mavericks.
It worked OK for a week after upgrading then stopped. So now having to use web mail to send email.
Strange thing is I receive mail OK, just cant send.

HT1589 problems with itunes after updating..can't locate some of my songs..some have an exclamation point beside them how do i get these songs back in my itunes

I'm having problems with itunes after updating. I've lost all my playlists,,finally played around with it and got the songs back but some have an exclamation point beside them and can't be located. they are songs i've purchased. I'm not very computer literate so this is a major problem. I have spent hours with this. I just want all my songs to play even though I'm not happy that I have to recreate my playlists. It would be so much easier if I knew and understood how to correct this. Has anyone else had this problem and if so..is there an easy way to correct it?

Not sure how this is an ipod touch question.
Perhaps you should post in the itunes forum.

Ongoing problem with newsletter-eMail-actions: CF is hanging

Hi forum-members, we have an ongoing problem with
newsletter-eMail-actions.
We use CFMX 7.02 Entperprise on Win 2003 Server. (between
100.000 and 200.000 receivers).
The deep links into the shops are of the following structure:

In the highest hours we have between 80 and 200 current
users/connections
per second. We are running two HP 380, 3 GB, CF-Servers in a
static loadsharing.
From time to time CF gets unresponsive and I don't know why.
We use fusion reactor and there are no long running requests
from
what I have seen, when CF is hanging. There is nothing in the
logfiles which is obvious to what it could
be related what is casing it. Does anybody have any idea what
else to look into ? Uwe: confused;

Problem with screen after update

hello,
I have a BB Passport and I have a problem after the last software update OS 10.3.1.1565
- the screen is flashing when i go into an application... This happens randomly... not every time. First I had this problem with Evernote. I erased everything from my phone and I performed a full wipe (factory reset). The problem is not solved. now is happening more often... when I go to settings, when I open an app... and so on. Usualy is flashing white screen, but last night when I wanted to watch a video, it flashed green screen...
Is there a way to solve this problem? Is this a software problem? Or I have to replace my screen?

Problem with sub-screen actions on Cancel button

Hi all,
I have a problem with sub-screen.
I created a subscreen (screen sequence in MM01/MM02/MM03). When users leave this screen, I call POPUP_TO_CONFIRM to ask if they want to save the data.
1) My goal is: when they choose Cancel, no actions are performed and users will see the current screen. However, I cannot use command: SET SCREEN 0 or LEAVE TO SCREEN 0 because the system gives an error message:
*SET SCREEN not allowed in subscreens*.
2) How can we determine when the user leaves the screen? which value of SY-UCOMM will be used to check this?
Thanks in advance.

for dis SET SCREEN is not required.
Consider d code given below as n eg:
CALL FUNCTION 'POPUP_TO_CONFIRM'
    EXPORTING
      titlebar              = 'SAVE'
      text_question         = 'SOME _QUS'
      text_button_1         = 'YES'
      text_button_2         = 'NO'
      default_button        = '2'
      display_cancel_button = ' '
    IMPORTING
      answer                = l_ans
    EXCEPTIONS
      text_not_found        = 1
      OTHERS                = 2.
IF sy-subrc <> 0.
    MESSAGE e066.
ENDIF.
IF l_ans EQ '1'.    " when yes is pressed
   MODIFY db.
   commit work.
   leave program.
ELSEIF l_ans EQ '2'. "when no is pressed
    leave program.
ELSE.     " when cancel is pressed
ENDIF.
In above module when Yes is pressed it saves data den leave prog.
As no action is specified for cancel button it will remain on that screen only from which popup is called, in this way ur problem can be solved.
Reward properly.

Profile problem with Pre2 after doctor to 2.2.4

I used the 2.2.4 webos doctor to update my NA unlocked Pre2. On first boot, it prompted for a profile, and successfully logged in and restored. After rebooting the device (required), it stays at the 'hp' spinner logo indefinately. Initially I thought something was wrong with the flash.
I created a meta-doctor (to pre-enable developer mode), and performed the same setup. Attached is the /var/log/messages file from that. It appears that the LunaSysMgr service repeatedly crashes.
Plugging in USB (to computer) caused the 'hp' logo to go away, and I could see the background & "usb/charge" dialog. Regardless of what I selected (or if I dismissed the dialog), a LunaSysMgr crash would occur, punting me back to the 'hp' logo.
Eventually, we figured out it was a problem with "something" in my profile's backed up data. Creating a new profile did not show any issues, and the phone worked fine.
To fix the old profile, I used 'impostah' to activate to old profile, and used the 'backups' app to disable palm backups. After a full erase, and first-run activation on my old profile, the phone works correctly.
I'm not sure how much help it may be to inspect the issue after the fact (especially since I deleted my backup). Nonetheless, I figured it should be reported.
I can't seem to attach a file to a post. Here is my /var/log/messages. For reference, Here is the #webos-internals IRC log spanning the day I was troubleshooting the issue. My username is 'seq' in those logs.

Problems with Macbook after Software Update

I haven't updated my Macbook in a long time, so I decided it was time I probably did. Software Update had updates for iTunes, Quicktime, and a 2009-Security Update. Everything seemed to be going okay. After the downloading and installing finished, it said the Security Update couldn't be installed and moved it to the trash. Then it prompted me to restart my computer because the other two installed okay.
After restart, when my computer started back up, my Macbook is messed up. The doc is missing. I open a finder window, and it shows the main folders, but all the things on the right (where it shows the drive, applications, and such) is missing. I tried to back up my files, but it can't even read there is a blank disc inserted (keeps asking me to insert a blank disc). And it wont let me shut down my computer, or restart it. I click restart, and it seems like it accepts it, but it just doesn't do anything. The dashboard wont show up when you hit F12. This mac is all messed up.
I don't know what happened here, all I installed was iTunes and Quicktime from the Software Update (security update didn't install), and all this happened. Any idea what happened and how I can fix this?
I'm using Mac OSX Tiger 10.4.11.

Welcome to Apple Discussions.
There's a variety of things you could try, but first as to why it is doing this. Probably your drive was slightly corrupted. If it was minor you might not have noticed it, but when the updates tried to install, the whole thing compounded and led to a whole bunch of things missing.
First, try to repair your drive. Boot from the System installer disc that came with your computer or is the one for the version you currently have on there, select language if applicable, choose utilities, run Disk Utility and verify (and repair if necessary) the drive. You can verify a drive from DU on your main drive while booted but I have found this can result in incorrect reporting of errors. To repair your drive you have to run it from a drive other than the boot drive anyway.
Next, boot from your drive in [Safe Mode|http://docs.info.apple.com/article.html?artnum=107393] and repair permissions. You can repair permissions while booted from the installer disc but this uses the permissions configuration on the installer disc which may be out of date if you have run any updates on your computer. Booting your computer to Safe Mode restricts the number of things running on your computer while permissions are being run and does a bit of spring cleaning at the same time.

+Summary of above from BDaqua+ (couldn't have said it better):
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer (Edit: Do not use this disc if it is not the same general version as what you have currently on your computer, e.g. use a Tiger disc for a Tiger drive, not a Panther disc), then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes."
Report back after you have done this. It may be that you have to use a more powerful utility such as Diskwarrior.
Once the drive is repaired you can try re-applying the two updates, though often it takes a full archive and install, plus re-application of all updates, to get everything working again.

Finally, on updating:
Updating
Certain steps appear to minimize the risk of an update producing problems.
Number one is to make sure you have a bootable clone backup of your computer in case you do need to back out of it again. This is the only guaranteed way of not having to worry about the results of an update.
Some like to boot from their installer discs or an external backup and verify (and if necessary repair) their internal drives as well as drive permissions. This is done with Disk Utility. You can verify a drive while booted from the same drive but sometimes this produces spurious errors. Repairing a drive (if necessary) has to be done while booted from another disk.

You can also go to the step of booting into safe mode to do the install.

I like to download the update onto my computer and install it from there rather than let Software Update do it. I know a few people who had problems with doing the update via software updater found a manual install to work.
Repair permissions again afterward.
It helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
The more cautious even like to unplug third party peripherals (see [comment by BDaqua|http://discussions.apple.com/message.jspa?messageID=9040746#9040746]).
Almost all of the above steps (except backup) have been questioned (e.g., [Permissons repair|http://www.macworld.com/article/52220-3/2006/08/repairpermissions.html] as to necessity. Probably many people have done successful updates without doing them. I say they can't hurt, they can very likely do good (especially if your computer isn't regularly maintained), so why not do them to be safe?

New air problem with battery after upgrade to 10.6.5

Hi List.
I bought new air about month ago. Everything was working like a charm.
2 days ago I did macos upgrade and I have big problem with battery performance. Only 2 hours of working after full charging. I decided to downgrade system to 10.6.4 and problem's gone.
Is there something wrong with 10.6.5 on new air?

Hi,
I dont think there is something wrong with 10.6.5 simply because I have no problem with it
Since battery management is one of the SMCs, resetting it may solve the issue.
