How can I get the jar location of a class (the -Xbootclasspath case)?
Hi
I'm using -Xbootclasspath/a to append a jar into the "ring 0" of VM. Inside my class, I want to find out the location of the jar so that I can find other resources that's deployed along with it. How can I do that? I try the standard getProtectionDomain().getCodeSource().getLocation() way but it seems a class in bootpath returns null at the second method.
Currently I have to manually feed the path into the app using an environment variable, but I'd like to know if there's a better solution.
Thanks
Weijun
This is not exactly the answer that you are looking for but If your are interested into the BOOTCLASSPATH value, you can get it with JMX.
RuntimeMXBean mx = ManagementFactory.getRuntimeMXBean();
System.out.println("BOOTCLASSPATH:\n"
+ mx.getBootClassPath());Bye.

How can I get iTunes to locate and play all my music files?
How can I get iTunes to locate and play all my music files?
I have this problem too. I am researching now. Here is what I know so far. If you right click a song then get ifo the it will say Protected AAC or purchased AAC. Protected wont play on sonos, purchased will play on sonos. It seems that all my protected were purchased 2005 to 2009 or so. I am trying to find out if apply will convert these for a small dfee or if I use the itunes cloud these tunes will convert for me. downloading and reloading is not an option for me. Pretty much a money grab by apple either way. I am sure Steve is smiling.

When importing the albums from a folder, the tracks for some of the albums were split up. How can I get them in one?

Not true at all.
You only buy the right to your own personal use.
You do NOT have the right to distribute to others.
This is illegal. There is no doubt about it -
How can I get my books that I download from the Library that are WMA files into my I tunes so I can listen to them. They have a ton of books but I can only listen to them from my windows media player and I wouldlove to download to my I pod but I have tried everything I can think of it they won't go over. Someone said all I had to do was copy them over and they would convert but I can't even get them to copy. Thanks.
Well it started happening AGAIN with my 2nd IPod. No matter what I did, it Itunes would NOT restore it!
I finally installed Itunes on my hubby's PC at work and managed to get it restored there.
Apparently, there must be some sort of compatibility issue with the windows version of Itunes and some other piece of software on my pc.
And one more important thing! I had to follow the instructions in the other thread that talks about how to correctly uninstall itunes and quicktime, in order to completely eliminate ALL traces of my "first" ipod's existence so it wouldn't demand that I restore it.
I think the software got "confused" and thought when I connected my 2nd ipod, that it was the 1st and that it still needed to be restored.
Basically, this is just POORLY written and POORLY tested software! -
How can I get a file to copy all of the files in a directory except itself and the source of the copy function will be the directory the final program is in? This application must be in Lab View 8.
you mean something like this (see below)?
Now you may have to implement code to check if the destination folder exists and to create it, etc. But if you use the Front Panel Control to select the destination folder, it should be okay.
Not the best implementation, mind you but you'll get the idea..

How can I get a list of active savepoints for the current session?
Hi,
In Oracle Applications, we are getting the following error while performing ROLLBACK to a Savepoint.
"Unexpected Error: ORA-01086: savepoint 'PTNR_BULK_CALC_TAX_PVT' never establishe d ORA-06510: PL/SQL: unhandled user-defined exception"
So how can I get a list of active savepoints for the current session?
Could you please also let me know if there is any better way to debug this issue.
Appreciate any quick response as the issue is very critical.
Thanks,

"Unexpected Error: ORA-01086: savepoint 'PTNR_BULK_CALC_TAX_PVT' never establishe d ORA-06510: PL/SQL: unhandled user-defined exception"It sounds like there's an execution path in the code where the SAVEPOINT is never issued.
There is no way to get a list of active savepoints. Is this your code or a "canned" procedure? If it is your code you can go through the code looking for answers, possibly tracing execution using DBMS_OUTPUT.PUT_LINE or writing messages to a log table. If its a "canned" procedure you may need to open an SR with Oracle -

When printing two-sided from my Mac on landscape A4 with 2 columns, how can I get my HP Photosmart 6520 to print the same way up?
Or, it is set the other way around (which makes more sense). Even though you are in Landscape mode, it is binding on the Long Side of the paper. Since you are in Landscape, you would want it to bind on the short side.
Think of the Binding like a Book. How would you flip the finished pages to read the “book.” Where it would be bound in the imaginary book is how you want it to print. -
