JAVA 7 on Mac OS X 10.5.8?!

I can't open any java file, it says "the .jar file could not be launched check the console for possible error messages". My macbook is running on 10.5.8, any versions of JAVA that works on this version?

Hi, Java 7 is out for 10.5.8
Locate the version of Java that’s installed on your Mac OS X system.
1. Open the Utilities folder and run the Terminal application.
2. Type java -version and press Enter.
(space between java & -v important)
The version of Java that you have installed will then be displayed on the screen.

ColdFusion 8 Fails to start after update Java for Mac OSX 10.5 Update 4

I have been using ColdFusion on a Mac for years. Now CF fails to start after I updated Java for Mac OS X 10.5 Update 4. I usually start by typing in the terminal window sudo /Applications/ColdFusion8/bin/ColdFusion start.
There is a crash report but I don't know how to read it. See attached.
Please help, I need this working for my job.
Thanks...Colin

Dear Craig,

I'm sure that this is 64-bit
CF 8.0.1 Enterprise Build 3080
I had moved the Java SE 6 to the top in both Plugin and Applications. The
correct version is showing in the terminal window. See below.

CF will not start. I have the activity monitor open, and when I start CF you
see it in the activity monitor for a few seconds as it starts up. When the
message process is completed in the terminal window CF disappears in the
activity monitor.
Any suggestions?

Hi, Colin,
My apologies but I forgot to ask 2 questions: (1) What kind of Mac you have
(Intel or PowerPC)? (2) What version of CF are you running and what installer
did you choose (8 or 8.0.1, 32-bit, 64-bit, etc.)?
To start, try the following:
1. Normally you'd shut CF down first ... but that's not necessary for you
2. Open Java Preferences again
3. Select Java SE 6 and move it (drag) to the top spot in both section (Applet
Plugin and Applications)
4. Open Terminal
5. Type java -version (you should see 1.6.0_13 as the new version)
6. Try to start CF again
This may not work (I've had issues with it) but it's technically how it's
supposed to work. With the Java Preferences utility, you're visually setting a
default JVM (you can do it with commands in Terminal but this is much faster
and easier).
If CF still won't start, look for the jvm.config file in your CF application
folder (try /Applications/ColdFusion8/bin or
/Applications/ColdFusion8/runtime/bin -- the latter is where a jvm.config file
is on my machine for a particular version of CF that's installed similar to
yours). You can override the JVM in this file but, hopefully, that won't be
necessary!

Java broken in Firefox after Java for Mac OS X 10.6 Update 3

After having updated my mac this morning with the latest Java for Mac OS X 10.6 Update 3, Java in Firefox is no longer working. When I open a site that contains a java applet (like javatester.org) I get the following output in the Console, and then Firefox hangs.

Any ideas??

Problem solved!
For some reason I had an additional "Java" Folder (/Library/Java) with a different Java sdk. After removing this folder and (just to be sure) replacing it with a symlink to /System/Library/Java everyting works again.

Can't print wirelessly since Java for Mac OS X 10.5 Update 4

I have an HP Officejet J4680 All-in-One, and have been printing wirelessly from my Macintosh (OS 10.5.7) since I purchased the printer in December 2008. However, after I installed the Java for Mac OS X 10.5 Update 4, I suddenly lost the ability to print wirelessly. I've spent hours on my own and on the phone with HP trying to figure this out, with no success. When I uninstall and reinstall the printer, I can get to the point in the HP Setup Assistant in which the network configuration has been successfully downloaded to the printer (I see an IP address, Subnet Mask, etc.), but then I get an error message of "Device Not Reachable . . . please make sure that your Mac has access to the network and retry." My Mac does have access to the network because I can get on the internet wirelessly.
I've tried entering the IP address manually, etc.--but nothing has worked. It's as if the printer is on the network, and the computer is on the same network, but they somehow can't talk to each other. Anyone else notice this problem, and how do I solve it?? Thanks in advance for your time!

Hello Laura C. I haven't noticed any problems with my wireless connections to my Canon printers, at home or at work, and I have the Update 4 installed. I also cannot think how this update would have impacted your ability to connect to the printer, except maybe due to a reliance of the HP software using Java to operate. But this should not have stopped your existing connection from working, only a new connection...
Apologies in advance if you have already been through the following, but if you were successful in entering an IP address manually, I would then check that you can get a response from the printer. The best tool to use is Ping. Open Applications > Utilities > Network Utility. Here you will see the Ping tab, as well as several other IP tools.
Before you select Ping, select Info (it probably has defaulted to this). This pane shows you the current IP address settings for your Mac. Since you are using wireless, change the drop menu from en0 (which is Ethernet) to en1 (wireless). This will show your current IP address set in the Mac. Make a note of this.
Now select the Ping tab and enter the IP address of the HP. Change the number of pings to 4 and press the Ping button. If the addresses are correct and the network infrastructure working you should get a response. If you get something like " 4 packets transmitted, 0 packets received, 100% packet loss", then that would explain the unreachable message.
The biggest cause of this symptom is subnetting. To explain further, an IP address consists of two parts, the subnet and network address. The subnet is determined by the subnet mask. If you have a subnet mask of 255.255.255.0, the your subnet is the first three sets of numbers in your IP address and the network address is the last number. For example, an IP address of 10.0.1.10 and subnet mask of 255.255.255.0 has a subnet of 10.0.1 and a network address of 10. For devices to communicate on a local network, they typically need to have the same subnet and a different network address. Can you confirm the subnets for the Mac and printer are the same and the network addresses are different.
If you get responses to the Pings, which indicates the IP addressing is okay, the other services like firewalls can stop some printer utilities from working correctly. Have you checked your System Preferences > Security > Firewall setting is set to allow all incoming connections?

Failed update: "Java for Mac OS X 10.4, Release 6"

In successfully updating to OS X 10.4.11 from 10.4.10 the subject java update, "Java for Mac OS X 10.4, Release 6", came up from Software Update. In trying to install it, it stalled at the very end of the installation. It again failed on a second try. Later on, using Spotlight, I checked my existing Java version to already be Java 1.4.2 plug-in settings -- the target update from java 1.4. Do I really need this Java Release 6? I'm running Sarafi 3.0.4 and Netscape 7.2. Thanks.

I'd be suspicious about an aborted partial install myself, have you tried the stand alone installer?
I'd Verify the HD, Repair Permissions, then get...

Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Actually, you cannot download Snow Leopard. You downloaded a Snow Leopard updater.

Thank you for any answer you might have

Should I install Mountain lion or it's not preferable for my Mac?
Also I get this note no mountable file system whenever I try to install the updates,literally I can't install any update :/

Installing "Java for Mac OS X 10.5 Update 6" (1.0) causing problems

Hi,
I installed the "Java for Mac OS X 10.5 Update 6" (1.0)" yesterday evening and it caused problems:
- network
- date/time screwed up
- Time Machine crashed
My environment is a MacBook Pro, running 10.5.8, all latest patches applied. During the install all other applications were closed (my once in three months cleanup of the desktop , Time Machine was not running although it might have kicked in during the download, I left it alone for install and the necessary reboot. I didn't hook it up to the power, had 82% battery left, afterwards (after all repairs) still 76%, so my guess is that is not the root cause, although I did get the power source warning and waved it away during the installs.
Looking back into the logfiles and using some gut-feeling I do think somehow the date/time seeting was screwed up and caused all other problems. The date was reset to the famous Unix starttime, Jan 1, 1970. At first I didn't notice, only after my network (Airport Extreme based) asked me WPA password and then complained about the date/time I noticed something weird.
After resetting date/time, verifying the disk for problems (none found), re-entering the WPA password, network ran again, had to re-connect with the Time Capsule and check the sparse backup-volume there before I got everything up-and-running again.
Not a very big deal, but annoying, and certainly something wrong in the update here.
Anyone any explains ?
Regards,
Wim.

Sorry if I missed it...have you scoured logs for anything that might shed light on success/fail during the install?

Java.crypto.Mac usage related to concurrency

My first question is:
Can I allow multiple threads to use the same instance of java.crypto.Mac concurrently? In other words, for example, is the java.crypto.Mac.doFinal(byte[] input) method thread safe?
If the answer is no, then my second question is:
If I have one separate instance of java.crypto.Mac per thead, in order to reuse the instance within a thread, do I have to call init(Key key) method every time before calling doFinal(byte[] input), even if the key value is always the same? I am asking this because we saw init method may introduce some overhead and we want to know whether we can avoid calling init again and again.
Thanks a lot!
John F

1.The javadocs don't say, so I guess you have to assume it is not thread-safe.
2. The javadocs do answer this, so read them.

Since that update my mac freezes when any scrensaver is activated.
Plus, i can no longer edit Google spreadsheets, neither on Safari nor on Firefox (i was able to do that before and i can still do that on a windows machine, though).
Has anyone experienced similar phenomenons and possibly found a solution?
I have not yet installed it. I usually wait for a while and even then I do a manual DL and install.
I don't know about the Google thing, but I don't know what the tie-in is with your screensaver, unless you are using some Java based 3rd party SW for running it.
The update included some security items to prevent a website from taking over your computer. While I personally don't trust Google to access my system, it's possible that Google has not make their system compatible with this new Java update.
And finally, it's possible that there is something wrong with the update.
You might be able to uninstall it but I would be careful and certainly make sure my backup was good.

Java for Mac OS X 10.5 Update 5 - Problems

After the restart I got the following error message:-
*"The installer could not validate the contents of the 'JavaForMacOSX10.5Update5' package. Contact software manufacturer for assistance."*
Does anyone have any advice as to what I should do about this ?

Thanks Topher,
After a few stops and starts in the downloading process, I finally downloaded it and it has installed without trouble.
Once again, thanks for your help.

Blocked by Java for Mac OS X 10.5 Update 3

Hi!
My Java application which uses network connections to external hosts now fails with errors like these:
connect failed: Connection refused
write1 failed: Broken pipe
write2 failed: Broken pipe
Done.
As this worked just fine prior to Apple's "Java for Mac OS X 10.5 Update 3" I think this update is the reason for my problems.
Can anyone explain what I need to add to my code to overcome these problems, please?
Alternatively a URL to such a tutorial would be welcome.
It seems the additional security of Java for Mac OS X 10.5 Update 3 means I need to add "something" to my working code (which, incidentally, still runs unchanged on an un-patched Mac)

Deary me
Embarrassingly, +mea culpa+
Amazing what doing it over with a reboot between the OS X patch and Java update can do with a final reboot - anyway, that seems to have fixed it.
