Java on Intel Mac question...

Okay, this may sound link a lame question, but I gotta ask...
I have been developing Java code, using JBoss, on G4 and G5 Macs for years.
I develop and compile on my G4 Powerbook, and copy the code (EAR's, JARs', etc) to my boss's G4 Powerbook. Now he wants to buy a new MacBook Pro, and do the same....
My gut says "This is not gonna work"...so I would like for someone to verify,
that compiled Java code on G4 cannot just be copied over to an Intel Mac....
Oh, I'm still using 1.4.2 Java....
Thanks!

Try it. Seriously... try it. Your only tripping point will be any custom libs that you use which use JINI code. A standard JAR file will run just fine, as there is no x86/PPC distinction with Java bytecode. However, if you use namespaces outside the J2SE, then you might want to check on those to make sure they aren't using calls into the native environment. If they don't you should be green.

Intel-Mac question...

I have not yet used a new Intel based Mac yet. I have seen conflicting reports online about it's ability to run legacy OSX software, but no reports of OS9 Classic software. Does it run Classic, and if so, how well?
iMac G5 Mac OS X (10.4.4) I want a Quad Core G5 : )

Classic is no more with the Intel-based systems. There are mentionings that the program SheepShaver, http://www.gibix.net/projects/sheepshaver/ may allow you to emulate OS 9, but I haven't messed with that program enough myself to get it to work to say how effective it is. As far as OS X native software for the PPC models, they are emulated on the new machines using Rosetta. Some programs (ex. Microsoft Office) work, while others don't. Of the programs that you use, it's best to research and see if and how well the program works or see if there is a Universal patch or retail version of the software you want to use.
Hope this helps.

Java on intel mac

i have a video-text syncing program that is supposedly a java-based application. how do i tell if it has the "JNI" library issue that would cause it not to run on my mpb that i am waiting on?

Is it a true java application (as opposed to using java as something like a scripting language). if so, its probably fine.
Only way to REALLY tell is ask the developer if its using any JNI calls.

Intel Mac Mini, Firefox and Java

I'm running an Intel Mac Mini using Firefox; mostly it's fine, but sometimes it behaves as if it and Java Applets have had a falling out.
I have made sure that I have the very latest version of JRE to go with OSX, but when I go to http://www.f1.com and log on to "Live Timing", the frame comes up, but no steaming teacup, then the bottom LH corner says "Done", but the timing area is still blank. Live timing works in Safari & Opera on the same computer, and on any PC running IE6.
Going to the help section on the live timing box says to go to download the latest version of JRE from the Apple.com website - if I try to do this, OSX refuses the download saying it is older than the version already installed.
I have sent questions to both Sun & Mozilla weeks ago, but have received no reply; any ideas?

Dont really have any solution other than the fact that some browsers act funny on certain sites. I think it is specific to the browser, not the computer itself. I have encountered the same thing with certain applets. Also just wanted to give a shoutout from another F1 fan. Good season so far, I think Alonso has the Chin's number this year.

Problem with Java app on Mac OS X... works fine in PPC, not on Intel

Hi all,
I'm at a loss... I've always been under the impression that java is the same no matter where it's running, but I've come across something that surely counters that line of thought. At work, we use a java application from DTI to publish our newspaper. This app works just fine on Mac OS X 10.4.x on PPC Macs, but the same application doesn't work on Intel Macs, also 10.4.x.
The app launches and appears to be working fine, but there's a point where it must download some support files from the server. This is where it breaks with the error:
java.io.IOException: null, com.dtint.macutils.AppFile.decode
The corresponding entries in the console log show this:

If there are any other logs I can provide, let me know what would be helpful and I'll get them.
I've got no clue why this wouldn't work across platforms unless it was compiled for the PPC processor or something, but then wouldn't it either launch in Rosetta or not at all on the Intel? I'm a systems admin, not a programmer, so I've really no idea where to start looking.
What I have done to this point is made sure I'm on the latest Apple-released Java, as well as copied the Java files from the PPC to the Intel to see if there was something there. Nothing makes any difference.
This would be a major coup if I could get this working... does anyone have any thoughts or ideas about getting this to work?
Many thanks in advance!

Thinking about switching to Intel Mac Mini... questions for the cognoscenti

Greetings:
I've been checking out the new Intel Mac Minis and I was thinking of purchasing one to replace my AV computer (PC) in the living room, which the GF currently uses. She's a typical user: watches video files/DVDs, uses iTunes excessively , sends web email and surfs the Net.
I've fairly decided on an Intel Core Duo Mini. Since I know the basics about Mac, I had a few questions:
1. What's an appropriate amount of RAM for a non-power user? Would 1 GB be more than enough or overkill? I'm used to running 1GB in a Windows machine. Plus, I'm also used to popping in memory when I needed to upgrade, and I see that's not really an option on the Mini.
2. How would I integrate it into a Windows network? Would the Mini be able to share files with a Windows machine and vice versa?
3. Regarding network integration: how easily would the Mini integrate into an existing Linksys 802.11g home network?
Lastly, this isn't really an (easily) answerable question, but how easy do you think it would be for an average computer user to get up and running on a Mac after having used Windows machines all their life?
Thanks, I look forward to your responses.

Hello, I can only really answer Q's 1 & 3 as I've only owned a mini for the past 24 hours.
I purchased the Single Core after taking advice of the Apple Store staff in Manchester, they were quite helpful. I only really produce music (have used Ableton, Acid Pro etc on PC for quite a while), surf the web, do my banking etc so was advised that the Single Core with 512mb would be sufficent. I work for an ISP and have 10 years plus knowledge of Windows but I was prepared to listen and learn having never used a mac before. From my own experience, I'm used to having to use a pc with minimum spec ie min 1.2GHz processor, 1gb ram in order to produce music without any pops or clicks (latency), though sound cards also play a part. I've also had to keep internet activity well away from any PC that I produce music on in that respect. Anyhow, I'm going off on a tangent here but I was playing around with garageband last night and I've never known music production to run so smoothy on 512mb RAM, never known it before so was extremely impressed and certain I made the right purchase opting for Solo Core. You may not actually NEED the full 1gb though this depends what you're doing. To answer your other question, my mac slotted straight into my home nertwork without making any additional configuration.
i.e how long does it take to get used to a mac, I've found there is a learning curve but it's not THAT difficult, it's just the odd thing such as no right click of the mouse that takes some getting used to.

Java SAPGUI on Mac OS X questions

Hi,
I use SAPGUI 6.40r6 for Java on Mac OS 10.4.4, and there are some missing features / bugs which prevent me to work efficiently:
- Input History is missing, and it's THE FEATURE it should have to work more efficiently! How do guys at Apple computer work without it? Is it planned in a next SAPGUI release?
- Copy/Paste in ALV Grids, doesn't seem to work.
The only solution I've found is to launch Virtual PC to run SAPGUI for Windows!! It's heavy as SAPGUI is the only app I use on Windows!!!
I know that SAP is quite busy with the migration to Intel Macs but would really appreciate some improvements.
Any answer?
Best Regards,
Nicolas
ps: thanks to SAP and Apple for making great products!

Hello Nicolas,
to summarize:
It works to select text and copy using cmd-c in cells which are ready for user input.
It does not work to copy the cell content of a read only field using cmd-c, it only works with the context menu.
It does not work to select columns/rows and fill the clipboard with the selection.
I'll talk with the developer of the grid control about this. In case you want to be kept in the loop, you should file a bug report on component BC-FES-JAV.
Best regards

Intel Mac mini memory question

Hi,
I got an Intel Core Solo Mac Mini.
4 questions :
1- My mac has 512 mo. Is it ddr2-SODIMM memory (I think intel is different vs G5) ?
2- Is it 2x256 mo or 1x512 ?
3- I want to upgrade to 1 gig, do I have to buy 2x512 ou 1x1000 ?
4- Does this ram is compatible ? http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=221705 6&CatId=2268
It said "PC5400" but all the specs seems to be "PC5300"

Intel Mac Mini question

Hello all:
I am sure this has been asked before. In replacing the hard drive and RAM in my intel mac mini, one of the battery wires at the point where it goes into the coupler broke off. I had seen elsewhere that warned if this breaks, you may as well toss the device. Is this the case? Can this be replaced by buying a new battery line?
Any help would be very much appreciated since I have my daughter's computer now out of commission.

Hi Chris
Sorry to hear about the accident with the wire. Don't despair - you don't have to toss the Mini!
If it was mine, I would first take a close look at the connector to see if it be dismantled so that I could re-solder/attach the wire. If not, and assuming the connector is unique to Apple, I would source another connector from an electronics shop (you don't need anything fancy - all you are doing is connecting two wires that run a fan).
I'm reasonably competent with a soldering iron, so I would unsolder the old connector and then fit the new one. If you don't have a soldering iron or aren't confident using one, you need to find a hobbyist or repair shop that will make the changeover for you.
This isn't high-tech stuff, so no worries about screwing up the Mini (although you do need to be careful to avoid static discharges while handling the opened Mini - but then you probably already knew that before opening the case).

Intel Mac mini: upgrading questions...

Hi, I'm going to buy the new intel mac mini but I'm a little afraid for the graphic card inside the tiny machine...
What about music recording? (GarageBand, Logic Express...)
What about games? (Doom3, The Sims...) It's better than the nVidia 5200 that was inside the first gen of iMacG5?
What about video editing? It's the Mac mini fast enaugh to perform simple video operations or I need a more powerful computer? Maybe the new iMac?... Please help me!

I can't tell you about games, though if you scan through these Discussion threads in the next week or so I'd bet you'll find plenty of references to game playing on the new mini as people buy them and try them out. At the present moment, having only been announced a couple of days ago, there aren't many of the systems in actual use yet, so there's not much information to go on.
But it has to be said that it has always been a mistake to assume the physical size of the system reflects anything of it's capabilities. The PPC mini that has just been discontinued and which was slower and more limited than the new system appears to be was perfectly capable of running such things as Garageband, and doing complex video editing projects, so there's absolutely no reason to assume the new mini won't be more capable. The fact that it has an integrated graphics processor that shares RAM with the CPU has got a whole lot of people in a tizzy, but despite the comments some are making about it, they don't have any first-hand knowledge (as yet) and thus have no clue how well or badly it performs.
I'd urge you to find one of these systems in a local Apple store or retailer and play with it for a bit - I would expect you to be pleasantly surprised, even shocked, at how well it behaves. If you can't get access to one, watch these Discussions and read what actual owners and users begin to report, not what 'experts' are thinking.

Intel Mac :: Quick Question...

Morning folks,
Now we're well underway with the Intel Mac switch I've been
wondering as to
how Intel Mac developers are coping, ie. any known issues
with Xtras [such
as Buddy], etc?
I'm asking as I'm currently running both Windows and G4 boxes
- but looking
to combine the two through an Intel Mac - I'll be running
either Parallels
or Boot Camp for the Windows side of things!
Any thoughts, opinions and/or advice from your experiences
would be very
gratefully received!!
Many thanks in advance... Mark ;-)

check this link from INM (copied from DIRECT-L list):
Hello all,
For those that are interested, we have just published a white
paper
on the new Intel-based Macs to help developers who are
considering
supporting this new platform.
The paper offers an overview of the situation and some
guidelines on
what the transition will entail, including some special
considerations
for Director developers.
It also mentions the official position from some of the main
Xtra
developers on their plans to convert their Xtras.
A link to the paper and a brief outline are available on our
homepage.

Getting a new Intel Mac, Logic question

I currently run Logic Studio on my dual G4, which is finally starting to die on me. I am going to be getting one of the quad Mac Pros soon, and I wanted to make sure that my current Logic Studio will install on it. In other words, does the move to 10.5 and the intel mac mean I need a different version of the Studio disks, or will my current ones install and run without a problem?

Your Logic Studio disks (ie Logic Pro 8) will install fine on your new Mac Pro.
It is a Universal Binary installer which means it will look at you hardware and install the version appropriate for your chipset.

Intel Mac Tower / RAID Utility question

I have a new Intel Mac tower with three 500 gb hard drives and a RAID card inside. I am attempting to create a RAID5 with 2 partitions (one 60 gb for os and other programs, and another partition with just under 900 gb for file sharing) - Trying to install mac osx tiger server (10 Client version) on my 60gb partition. I was able to do the following: boot machine from Client Install CD that came with the tower(as far as I know the tiger server os disk that I purchased does not have a RAID utility on it), used the RAID utility to create a RAID5, used the RAID utility to create the 2 partitions. Everything appears to work just fine after the RAID builds and partitions are created on them. Now if I either attempt to boot from the install disk for either mac os x server, OR from mac os x client os, I get to the point where you choose the partition (or volume) to install the os on, and I see NO VOLUME in the window below. Am I doing something wrong? If I need to give more detail please let me know.
Thanks for any help in advance!
Eric

Hi there ... i think i see what your issue is about.
1) You bought a new MacPro CTO with the Raid card and want to turn your internal into a Raid 5 install.
2) The raid card is again spanking brand new hardware in the machine and the actual support for the card does not come before 10.5 Server which is still on the way but you can certainly circumvent the issue with using a external drive install 10.4.x on the external and clone the external to your internal raid 5 to use as your boot drive.
3) Make certain your partition on your 10.4 install is GUID on your raid. This is found in the Disk Utility options under the partition tab.
4) Make sure your Mac os X server install DVD is 10.4.x Universal .. Do not use a 10.4 Server for PPC on a MacPro you ll meet 20 tons of worries . I would as well run the updates on the external drive first so when you clone you are up to 10.4.10 with all appropriate updates and utilities . As a safety measure installing your AppleRaid Card utility on the external drive would be a wise move so if they are updates to the utility they shall be taken into account.
For a good clonning utility look for carbon copy cloner . it is not one of the fastest cloners out there but it is ROCK solid and fully supports 10.4.x server and a life saver as well.

Can I use OS9 as the start up disk on my Intel Mac?

I have a new Intel iMac. I want to partition my hard drive, install OS9 and run the old system. I know I can't use "classic" on 10.4.7 but I wonder if I could simply install OS9 and reboot my computer. I don't need to move between the two, meaning I don't need to work in OS9 then instantly click and be in 10.4.7. I can deal with the inconvenience of rebooting.
I'm having 3 problems
#1, I have an old version of Photoshop. I'll buy the newest Photoshop someday but the latest version wasn't made for Intel Macs and it is very expensive. $600. I wonder if it runs slow on Intel Macs. Maybe I should wait for the next version.
#2 I have a great Epson printer (875 DC) but Epson has not updated the print drivers for this model and probably won't. OK fine I can buy a newer better photo printer $550.
#3 I have a "Nikon Coolscan 4000" film Scanner $1,300. This scanner is great in OS9 but the thing never worked in OS10 and now that I have this Intel iMac I downloaded the latest software update and the thing still doesn’t work and if the computer sleeps while the Nikon software is open it won't wake up and I have to restart.
To sum everything up, can I run OS9 on my Intel iMac? I don't care if I have to work in OS9 then shut down and restart to work in 10.4.7 Can this Intel iMac understand OS9. If I try to restart using OS9 as the startup disk will I damage the computer? Will I screw things up and have to spend hours and days removing files and correcting problems?
I feel like this computer is a fresh clean new baby and I'm afraid that if I start messing around with it I'll regret it.

Hello,
I have a new Intel iMac. I want to partition my hard
drive, install OS9 and run the old system. I know I
can't use "classic" on 10.4.7 but I wonder if I could
simply install OS9 and reboot my computer.
The problem here, is that the OS 9 environment / Operating System will only run on a PowerPC processor.
The only reason that OS X will run on either processor, is that it was specifically designed to do so from the beginning.
But, OS 9 and older were specifically written for the PowerPC / Motorola processors.
So, you will need a machine with a PowerPC processor to run OS 9.
Currently, there is one program that will enable OS 9 to run on an Intel Mac. But, it requires making a copy of the Power Macintosh ROM. So, it's legal use is questionable at best.
http://www.gibix.net/projects/sheepshaver/
This program works by emulating the PowerPC processor. And, it is reported to operate at roughly 1/8-th of native speeds. So, it could be pretty slow for productive photo work.
#1, I have an old version of Photoshop. I'll buy the
newest Photoshop someday but the latest version
wasn't made for Intel Macs and it is very expensive.
$600. I wonder if it runs slow on Intel Macs. Maybe I
should wait for the next version.
If it is a Mac OS X version, then it will run on the Intel systems. But, yes it will be slower. Usable, but slower.
I haven't tried this program, so I cannot personally comment on it. But, even Steve Jobs admitted it was slow on the Intel Macs.
#2 I have a great Epson printer (875 DC) but Epson
has not updated the print drivers for this model and
probably won't. OK fine I can buy a newer better
photo printer $550.
OS X comes with drivers for the Epson Stylus Photo 875. They are provided by the Gimp-Print layer. But, installed / select just like any other printer. So, as long as you can connect the printer using USB, then you can select the driver for the 875 and be fine (as long as this is the same printer).
Otherwise, some people have reportedly installed PowerPC print drivers without trouble. I haven't tried it myself.
#3 I have a "Nikon Coolscan 4000" film Scanner
$1,300. This scanner is great in OS9 but the thing
never worked in OS10 and now that I have this Intel
iMac I downloaded the latest software update and the
thing still doesn’t work and if the computer sleeps
while the Nikon software is open it won't wake up and
I have to restart.
Can't really help you there.
To sum everything up, can I run OS9 on my Intel iMac?
I don't care if I have to work in OS9 then shut down
and restart to work in 10.4.7 Can this Intel iMac
understand OS9. If I try to restart using OS9 as the
startup disk will I damage the computer? Will I screw
things up and have to spend hours and days removing
files and correcting problems?
As mentioned above, the only method currently available to use OS 9 on an Intel system is that SheepShaver program.
But, I would not expect good results with it for your uses. And, it's legal status would be questionable since you need to copy a ROM file from another Mac to use it (which goes against Apple's license agreement).
I feel like this computer is a fresh clean new baby
and I'm afraid that if I start messing around with it
I'll regret it.
Just make sure you have a good backup of everything before you start experimenting.
I hope this helps.

Slow performance on Intel Mac a damaged disk?

Hi,
I'm experiencing very slow performance on my Intel Mac 216 Ghz core duo, with 2GB 667 MHz DDR2 SDRAM. Running OS 10.6.8. Have been experiencing reduced performance, can't use Entourage email or Chrome, Firefox browsers at the same time. Ran Utilities to repair permissions, only a Java set of issues. Disk Utilities found no problems with the disk. Have experienced this issue increasingly for 5-6 months. Using Activity Window i see that Entourage, Word, Safari, Chrome, even System Preferences pane sometimes "Is not responding". Other system services take longer than before.
Apple support had me get larger RAM chip. Now have 2GB Ram. Upgraded to OS 10.6.8 with no improvement. Ran Software Update several times.
I have no anti virus software, have disabled Spotlight and any other memory demanding software. I'm on a in-home wi-fi network on an Airport Extreme.
In addition, at startup it takes 15+ seconds for the keyboard (wired) typing to show in the log on field. Running a single account with Admin access. Screen refreshes slow at times. Currently running is Safe Boot mode but that's not helping much.
Read on this board discussion 23238910 to use Terminal Window to do a syslog comand. The results in the Text Edit reads
Thu Jun 5 14:29:54 strait-admins-computer kernel[0] <Debug>: disk1: I/O error.
Thu Jun 5 14:32:25 strait-admins-computer kernel[0] <Debug>: disk1: I/O error.

Fri Jun 6 09:07:00 strait-admins-computer kernel[0] <Debug>: disk1: I/O error.
I need to resolve the issue as it's killing my time!
Thanks for any suggestions.

It does not sound good for your disk drive.
I suggest you backup everything to an external disk drive ASAP.
