Oracle JDK 8 .jar file does nothing

[Ameen]

Hi All,

I have had a problem with a .jar file not opening when I click on it and run it, nothing happens. here is the result of Java -jar jadpcm.jar: Error: Could not find or load main class com.silogic.rtc.adpcm.ADPCM I am running Linux Mint 18.3 Cinnamon 64-bit version 3.6.7.

Hello, Ameen.

Is this jar file jadpcm.jar really a self-contained standalone jar file? If it is not, but if it belongs to software package, you may not be expected to launch it by simply double-clicking it.
Maybe it depends on other jar files and on a correctly set CLASSPATH? Who knows?
Definitely more details are needed on what jadpcm.jar really is and on what the developer's instruction is on how to launch it.

Regards,
Karl

Yes, I believe the problem is with the Classpath here are the instructions:

Run the "jar" file with:

prompt> java -jar jadpcm.jar

You'll need to install Java. I'm not sure the "open java" that's on many linux's will work. If you can't get that to work, try the one from Oracle.

Here is a link to his exact post with the file: https://ogrforum.ogaugerr.com/topic/pla ... 5271633593
Wait for it to load then it will take you to his post with the attached file.

Any Ideas?

Hello, Ameen.

After having read the linked thread, I wonder whether it is really worth the time to try and run the jar file.
To me it reads as if this is a part of some never completed java application.
From my perspective there is not much point in spending any more time on this Java something.

Regards,
Karl

Hi "Ameen",

Welcome to the wonderful world of Linux Mint and its excellent forum!

It would help to know more about your system setup. If you run "inxi -Fxzd" from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.

I downloaded the zip file from your link and extracted the contents which included the "jadpcm.jar" file and samples and it brought up this application and I could play the files using both OpenSource (openJDK) Java 8 and Oracle's Java 8, see screenshots. I used my file manager to right-click the file and opened it using either Java runtime.

Tip: You must have permission to run certain files like Java jar files. Just right click the jar file, select properties, permission tab, check the allow execute or executable box, click apply, ok. Then you can run it.

You must have Java installed which "openJDK" v8 usually is in all editions and versions of Linux Mint. I like to install both Oracle's Java and OpenJDK runtimes because some great Java applications will use either one.

"While very popular at the end of the last century, ADPCM is no longer a
common audio encoding format, and is certainly not recommended as a general
purpose encoder."

I also found these links.

I searched the "Synaptic Package Manager (SPM)" for ADPCM and already had "libsnd", etc... installed

Oracle Java and Open Java installation

The Java runtimes are probably available in the Software Manager or Synaptic Package Manager (SPM).

The first problem has been fixed by running this: sudo apt-get install openjfx now the file opens but after playing one sound the thing freezes, what is the fix for this? I already had the run as executable file ticked on so that was not the problem. As you can see the company that records these sounds use the ADPCM format to install onto their system so I can't really change that.Btw keep the volume on low since some of the recordings are pretty loud.

Hi "Ameen",

"openjfx" is a very good Java package to install for multiple Java processes, how did you figure that out? I'll add that to my instructions for installing Java.

I have never used this sound format or this particular Java application before. And FYI: I never installed the "dbry/adpcm-xq: Xtreme Quality IMA-ADPCM Encoder / Decoder" which if you really want to use this format, then installing this might be a good idea.

When I ran the Java app for this sound codec, I had to click each sound file in the lower box, then click play. It did not lock up, but it was not automatically playing the next sound file or the whole "mth" sound combo file.

What type of computer are you using? I have never heard of this "GOOGLE (portable) Peppy"? It does not have much CPU power or system memory (only 2 gb ram), so you might be better off using one of the other Linux Mint editions rather than the superb Cinnamon edition which requires more system resources, I recommend "Mate" or "Xfce"; Xfce requires the least amount of computer resources, Mate is the most hardware compatible.

You might be able to use "ffmpeg", or some other application, to play or convert the combo sound file or each track?

Hope this helps ...

This is an Acer c720 (Peppy), Which Linux do you recommend and which one looks the most like mint? The reason is that right now my Linux mint looks like windows 10 because I like the look of Windows if I can put a theme on the other operating systems than give me a recommendation and I will do it right now. Can I download Linux mint mate? How do I install the "dbry/adpcm-xq: Xtreme Quality IMA-ADPCM Encoder / Decoder" software?

[phd21]

Hi "Ameen",

If you can add more memory which is relatively low cost nowadays, then you could do that and keep using the Cinnamon version, although you might still want to check out the other editions.

Can I download Linux mint mate?

Anyone can download any edition of Linux Mint, there are four wonderful editions of Linux Mint: Cinnamon, Mate, Xfce, and KDE (64-bit and 32-bit), yours is 64-bit.

They all are graphical desktops and thus work very similar to MS Windows, some (or all) can even be "themed" to look like various versions of MS Windows. I would recommend that you download and burn a USB stick or DVD of each one Mate, Xfce, KDE, boot up to that and try it for a little while 1/2hr - 1 hr or so. Xfce or Mate would probably be best for your current hardware configuration.

Hope this helps ...

[Ameen]

alright, I will try that right now do I need to do any configurations to my system if I just try them out on a USB?

[phd21]

HI "Ameen",

Not at all, just go for it...

And, keep us posted... Ask questions if you need answers.

[Ameen]

Interestingly the download stops at a certain point. Any ideas?

[Ameen]

Any help?

[phd21]

Hi "Ameen"

Please be more specific. What are you trying to download and how, from a browser (which one) or a torrent link? Try a different download mirror link if downloading from a browser.

You must have at least 2gb of space on your drive to store the Linux Mint iso file download, then you must use a USB stick creator to burn the iso file to the USB stick.

Download - Linux Mint

Hope this helps ...

[Ameen]

I am trying to download xfce through chrome, then firefox and both don't work. I tried several mirrors. I also tried Mate with the same results.

[Ameen]

Now it says Network error but I am using Xfinity which should be good.

[Ameen]

How good is KDE compared to Xfce and MATE would it be a good solution for me? Also are there any differences between the 4 systems like maybe different softwares or commands?

[Ameen]

I just searched up KDE and it looks beautiful, would it be good for my device which is slow?

I just searched up KDE and it looks beautiful, would it be good for my device which is slow?

Probably not. KDE, Cinnamon, and Gnome are more "heavy" desktops, so they need to be run on computers that are relatively new and powerful. (Note that some people say that KDE isn't all that bad on low-end hardware, so your mileage may vary. I've always heard that KDE is generally a poor choice for slow devices, and my personal experience has also been that it's not a good choice.)

I personally like MATE and Xfce for low-end or slow devices - MATE I try first since I like it better, and if the computer is still to slow I switch to Xfce.
