Subsonic not finding java's jaxb on fresh Raspbian Buster in

[glucenag]

I love my Subsonic install on my Raspberry Pi 3. Just installed Buster (was running Stretch but I freshly installed Buster) and would like Subsonic back! Any help appreciated


**In brief:** fresh Buster install on a Raspberry Pi 3, usual Subsonic install steps followed and Subsonic throws this error in its log:

Code: Select all

java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

:


**Details:** I installed Subsonic following [this][1] and in particular installed openjdk-8-jre. Since Buster comes with java 11 by default and I was getting the previously mentionned error in the log, I uninstalled all four java 11 packages (jdk, `dk-headless, jre and jre-headless that is).

Code: Select all

java -version

says java 8 is correctly installed, returning

Code: Select all

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b01-1+rpi1-b01)
OpenJDK Client VM (build 25.212-b01, mixed mode)

I believe Subsonic requires java 8. I have also been reading that java 8 is no longer supported in Buster, but as per the above I seem to do just fine ?

In any case, here is the meat: Subsonic starts and stops fine, and

Code: Select all

sudo systemctl status subsonic

is not suspicious at all, returning

Code: Select all

which I believe is OK. However, at http://localhost:4040 I get:

HTTP ERROR: 503

SERVICE_UNAVAILABLE

I thus grep'ed Subsonic's log for errors and got a bunch of

Code: Select all

java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

I googled that but nothing is too Subsonic specific. I found [this][2] which seems relevant, but I'm not sure I understand the accepted answer. It seems this is for manually running some code involving java, but in my case I only need Subsonic to work. I thus fail to understand how to apply the possible fixes for java 8 mentionned in there in my case.

**More information:**

- I did add `JAVA_HOME=/usr/lib/jvm/java-8-openjdk-armhf` to `/etc/environment`
-

Code: Select all

sudo apt list --installed | grep openjdk

returns

Code: Select all

**Bottom line:** Subsonic clearly fails to work because of a java-related issue. If java 8 is indeed installed correctly (and supported!) on my Raspberry Pi 3 running Buster, then I would only need a way of adapting / understanding the fix [here][2]. Any other way of making Subsonic work would open the doors of Heaven for me, folks!

I can't believe I am the only one who tried to install Subsonic on a RPi3 running the new Buster ?

[LRanger]

I'm running Subsonic on an Odroid HC2 (both are armhf as I know) with Ubuntu 18.04. Have a read through this thread http://forum.subsonic.org/forum/viewtopic.php?f=2&t=17957&start=30

Hey there. Thanks for reacting but I guess this is not really the same ? I read that thread too but did not find it of any use - was there something specific you'd say I missed ?

[LRanger]

I'm running Oracle's JVM, not OpenJDK, may be worth a try.

Hi... I'm in the same situation as you .. I used a raspberry pi4... and i got the same return with my web interface .. do you find any solutions ?

Thnks for help

I'm running Oracle's JVM, not OpenJDK, may be worth a try.

Wait: are you telling me you are running Oracle's JVM as in "I'm running it *and* Subsonic works" ? If so, what machine are you on ?

EDIT: sorry, did not see you are the same person as the reply above. Thanks, I'll maybe give a go, but it seems installing Oracle's JVM in Buster is a little mess. Before diving into that I would have love to know if there is a less hacky solution.

@urbexophil, no, I haven't found a solution yet. Be sure I'll post it here if I do.

responding to this a full year and more after your original post. curious if you found a solution.
i recently installed buster on my pi 3 and got the same 503 error.
but i had also bought a pi 4 and was planning on moving subsonic to the 4, so didn't bother with the 503 error.
to complicate things, i chose to install the experimental 64-bit buster os on my pi 4, along with jdk 11.
installed and ran subsonic and got the "jaxb" issue. being a java developer, i painstakingly downloaded and copied required jars to the subsonic WEB-INF/lib directory as i got new NoClassDefFoundErrors. ultimately subsonic started without any errors, but when i went to http://localhost:4040, it threw a whole host of critical errors 'cannot resolve java.lang.Class' and JasperExceptions, which tells me subsonic isn't going to accept my franken-install with manual jars copied in.
not sure what to do at this point. search for an alternative to subsonic? bothers me that jdk 8 is maybe a decade old now and subsonic hasn't upgraded itself to the newer jdk/jre versions.
