.jar conversions for ipad

These are PPTs from my professors. They are the slides plus the professor's commentary for each slide. So, no, it has never been resolved, as that is the format in which they post these required listening/reading presentations they do.

You can unrar a rar-file and unjar a jar-file, like you can unzip a zip-file. It just are other forms of compression.
Try 7zip (freeware from http://www.7-zip.org/download.html) to extract the contents. The program runs on a PC, for exampe. Then copy the extracted contents to your tablet.

Since this is somewhat uncommon, I should expect it's explained somewhere in the course material how to do it.

PowerPoint slides include the notes I made. Once we get the PPT out of the jar we can view them in many ways.

I can't guess how long you've been using PCs and Apples but there are more ways to solve this than I can list. Unless you insist it stay in the jar.

Thanx, I don't need multiple ways, but any one that makes it playable like a video on an ipad. A previous professor used to do her narrated PPTs in mp4 format, which was much more convenient. I would like to find a way to for example convert a .jar file to an mp4 or something along those lines. I really don't want to just unpack the files and separate out the PPT itself from the narrations that come with it.

(This is why I have never wanted an ipad, but unforunately, the program I am in requires it. Give me a laptop any day!!)

MP4 is not a standard so to play those I'm back on my PC to unpack the jar then possibly convert it with HANDBRAKE. It's a shame you don't get with the teacher and volunteer to help them make ready to use iPad content.

In parting, these titles I love to use.

1. VLC Player.
2. Handbrake.

Yes, well the irony is they require the ipad and then post these files that don't work with it. But I honestly think it's b/c they might not be able to/know how to choose something else, as I'm hardly a savant myself.

That said, mp4 was just a random example b/c I did have a professor who used it and that was so much easier to deal with. Are you saying that there is no possible way to put these into an ipad friendly format without first unpacking them and then converting into, what? What would handbrake even convert them into?

It will of course reach the point of diminishing return, where I'm spending so much time unpacking, repacking, converting that I might as well sit on my laptop. I was, perhaps naively, hoping for a one step solution.

Now there could be some play here for you to create a solution and market it. But before you have a software to do something, there must be a need. Now you need (or want it.)

Frankly this seems like a great idea for you to create a web site that does it for you.

take a look here at the first few lines.

Jar stands for Java archive, as far as I know. And I really don't think the lecture notes are Java classes. So I wonder why any professor would choose that to distribute anything else than a Java-program, when there are common alternatives like zip or (somewhat less common) rar.

I even wonder if it really are jar-files. The OP didn't tell if he could extract the contents after all our help, and what actually came out.

Kees

There are so many tools to unpack a jar-file on a Windows laptop, that I'd use that for that task. Then it's your own choice if you want to 'read' or 'view' or 'listen' (or whatever) the unpacked content on that laptop or on a tablet. That might depend also on what the content actually is.

Kees

JAR is simply one way to put together these files, but not the only way. Perhaps there's something odd about what's inside and the audio isn't simply embedded in the PPTs(?)

I would simply follow Bob's advice and unpack them all. The free Office Viewer software for iOS can handle the PPTs. Audio should be embedded inside w/o having to convert to a separate video file format such as MP4.

Maybe you could post an example in dropbox we could see(?)
