for whatever reason, i'm unable to use some of my java classes.

they are classes that need 1.5 features; i had therefore added

to the config file and was successfully using things. however, since then i've upgraded to 4.5.6 from 4.5.5 and to 10.4.5 from 10.4.4 and now i get this error:

? error: java.lang.UnsupportedClassVersionError: ali/msp/migrator (Unsupported major.minor version 49.0)

? error:     at java.lang.ClassLoader.defineClass0(Native Method)

? error:     at java.lang.ClassLoader.defineClass(ClassLoader.java:539)

? error:     at com.cycling74.max.MXJClassLoader.loadClazz(MXJClassLoader.ja va:88)

? error: Could not load class 'ali.msp.migrator'

i am able to compile the code, and a .class file is created. however, when i put the name of my class in an mxj, i get the above error. if i put it in an mxj quickie, then i get no error until i double click, at which time i get the error and the mxj objects starts flashing and never stops. if i delete the object and put down another mxj quickie, it's flashing right away.

java-1-5-version-troubles-again

I'm guessing you already tried this, but it wasn't mentioned in your

email. did you re-add the max.java.jvm.version 1.5 to the config file

after upgrading? The upgrrade might've changed it.

yes, that line is still in the config file...

the most recent builds of java 1.5 for os10 now set it to be the 

system default, instead of leaving 1.4.2 as the default. try running 

java -version from a command line and see what it says. java 1.5 

works in max here w/o having to fiddle with any max config files at all.

Hmm. Of course, you'll need to add the config line for each new 

version of Max/MSP (probably: I always install distinct and separate 

Max/MSP releases, rather than upgrade). I've done a series of OS X 

upgrades and have not seen these java problems.

Not here it ain't. "java -version" still reports 1.4.2_09. This is OS 

(The Java 5 I'm running is 1.5.0_05 - I think it's Apple's Release 3.

X 10.4.5.

I love these version numbers.)

i have the latest apple java release installed, i.e.

http://www.apple.com/support/downloads/java2se50release3.htm

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232)

Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode)

on top of that, it seems that the line added to the mxj config file doesn't change anything...

note that 10.4.5 does not mean you magically get java 1.5, java 1.5

i did that months ago when i installed 1.5 for the first time, and the settings are still those...

hi wes,
thanks for the help.
i'ave already used

Then I've maxed out my JAVA knowledge. I think updating to the latest

apple release this the best solution then.

As far as I know, this only changes the default Java system for 

browsers, and is not terribly useful for anything else. I don't know 

of any other preference settings. I just modified the shell search 

path in my .bashrc to get java 5 for console programs.

whoops, my bad. I assumed that there wasn't a public release of java 

1.5 yet, but apparently there is? anyway, I would recommend signing 

up for a free membership at developer.apple.com. inside, you'll get 

some preview software, including release 4 dev preview 6 of java 1.5. 

release 4 dp 6 is what gives you 1.5 as the default jvm on your system.

Don't think so - you can go straight to www.apple.com/java and

Odd. Once I had Release 1 in there, Release 3 came as an automatic 

system update, but this Release 4 isn't coming down the line (yet).

Don't think so - you can go straight to www.apple.com/java and  
download it as an ordinary punter.

system update, but this Release 4 isn't coming down the line (yet).

and that seems to have solved the problem.

however, note that for whatever reason, this line in the mxj config file

i tried to send you an email yesterday with a debug version of mxj that will hopefully give us more insight into what is going on.The list stopped it because the message was too big. Is it possible that you have more than one max.java.config.txt? Also it might just be working because the latest 1.5 update might have changed the links in System/Library/Frameworks/JavaVM.framework/ to point to 1.5 as the current version. I will send you the debug extern when i get home. If you have that property defined in max.java.config.txt it should definitely print something to the console. OK. Take care.

yes, of course. thanks for the hint topher, i should have looked for a second max.java.config.txt file and indeed, it appear that IRCAM's FTM comes with it's own max.java.config.txt (!@#$). very annoying but i should have expected it.

> Nick, could you share the magical line you put in your .bashrc to 

It's just an alteration to the shell's search path, so that when I 

say "java foo" in a console window I get Java 1.5:

JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versio ns/1.5/Home

> I don't think I need to change the links in

You could modify the symlinks to make Java 1.5 the default, but that 

could cause upset to a System Update run at some stage, and, for me 

at least, the things which need to know about a nonstandard Java 

so it's a path of least disturbance to deal with them individually.

to change the shell, there is more than one way.

there is sh ksh csh tcsh zsh bash in your /bin

this does not change the shell when you log in remotely.

chsh -s changes the netinfo database as well.

a good source. here is what I found

with the introduction of Panther (10.3) the default shell is no  
longer tcsh but bash,
because of its support for unicode.

open Terminal > Preferences
enter /bin/ksh or whatever you prefer

this does not change the shell when you log in remotely.
to change that too, use netinfo.

Fair enough. My TiBook has been through a series of incremental 

upgrades from 10.1 upwards, and my shell was still tcsh, but on my new-build Sawtooth it is indeed bash, as it is on my Mac mini (10.3->10.4). Terrific.
