Title: JCZ does not work in linux and openjdk 8
Post by: forumisto on January 23, 2018, 05:46:12 AM
Hello

I have tried to run JCZ 3.4.3 in linux mint. For that I have installed openjdk-8 (the default jdk).

The machine is a Core2 Duo E8400 with 8GB  RAM. The SO is Linux Mint 18 64 bits.

Have you tried to execute in linux?

Thanks

Hi Forumisto,

I'm on Ubuntu 16.04 LTS.
I have a Intel Core I5-3210M and also 8 gb of ram 8)
64-bit.
JCZ 3.4.3 is working on my machine. So it is executing here. Do you see something starting, a logo perhaps???

I tried to download the lastest version but that one isn't working for me :( ??? But 3.4.3 works :D

It would be worth sharing your execution error, it will likely provide some clue as to why it's not running on this strain of Linux+java.

it looks like it failed to load an xml file that's checking for an updated version of JCloisterzone.

I have a feeling it may be trying to download it and your java doesn't have read/write access to the folder.

Can you provide the content of your config.yaml file too, the update URL may be in there?
But if not the default is: http://jcloisterzone.com/version.xml

But if you don't have Internet connection, anyway the program starts.

I remove openjdk and I installed oracle jdk 9 and the error is the shame.

Now I'm wondering if your machine has internet access and is unable to load the version file.

I tried to create a yaml config file to specify a local version of the version.xml - however I just receive errors saying it can't load the file.

I don't follow you.  I've tried to start JCZ without a network connection: It was successful.

Are you able to try with an internet connection?

For what it is worth, I have been successfully running JCZ on Ubuntustudio, Mint and Edubuntu for over a year now and I have never encountered any problem with a single one of the releases.

I do seem to recall, however, that I used synaptic package manager to install 4 files of 'IcedTea' before I tried to use it. I'm not certain what 'IcedTea' does, as I thought that it ran Java in a browser, but it might help. Nothing ventured, nothing gained.

Hello

Finally I could run JCZ on my linux. I removed all openjdk packages (I had several installed) and installed the Oracle JAVA 8 from its PPA.

Stange error.

You don't need to turn off connection. You can instead comment out update url in config file. This disables update check.
