Java web start

troysie · 07-27-2021, 11:03 PM

Please could you tell me how to solve this java error. Do I need to download additional software

Code:

estelle@estelle-H81M-S2H:~/Documents$ javaws qs.jnlp
selected jre: /usr/lib/jvm/java-16-oracle
WARNING: package sun.applet not in java.desktop

sun/awt/AWTSecurityManager has been removed, so either you need to use an older java version or a newer software.
(actually I have no idea what is it all about, dropping in an error message is insufficient).

Does "qs.jnlp" refer to "QuoteStream" - the commercial software you were trying to run nine months ago?

The same quotestream and still trying. I am trying to get away from windows, quotestream is the only program I cannot get to run on linux. When I get it to work I am windows free

Then you first need to pay attention to the published requirements:

Since Java 11 and above are unsupported, the latest release of Java 8 LTS is the one to try.
Also, since they use Java Web Start it needs to be the Oracle version - the requirements links you to the relevant download page.

If that still doesn't work you need to talk to QuoteMedia - the company you paid for the software!

If they refuse to help, you can try running the Windows Desktop version in Wine, or (if there's no other software that does what you want) put up with Windows in a VM.

I have got java 8 on my system and have selected it from alternatives. I have run

Quote:

java -version

which shows me java 8 is selected. when I run

Quote:

javaws qs jnlp

it still selects java 16. How do I make it select java 8

Hrm... guessing that's could be JAVA_HOME or path related.

Can you provide the outputs for each of the following commands:

Code:

pwd
which --all java
which --all javaws
env | egrep 'JAVA|JDK|JRE'
echo "$PATH" | tr ':' '\n' | egrep -i 'java|jdk|jre|oracle'

(Using [code]...[/code] rather than [quote]...[/quote] will preserve formatting.)

Thanks for your reply, here are my results.

Code:

estelle@estelle-H81M-S2H:~$ pwd
/home/estelle
estelle@estelle-H81M-S2H:~$ which --all java
Illegal option --
Usage: /usr/bin/which [-a] args
estelle@estelle-H81M-S2H:~$ which --all javaws
Illegal option --
Usage: /usr/bin/which [-a] args
estelle@estelle-H81M-S2H:~$ env | egrep 'JAVA|JDK|JRE'
JAVA_HOME=/usr/lib/jvm/java-16-oracle
estelle@estelle-H81M-S2H:~$ echo "$PATH" | tr ':' '\n' | egrep -i 'java|jdk|jre|oracle'

Yep, that JAVA_HOME value is probably causing the issue.

To change the value for just one command, you can prefix it to the command, like so:

Code:

JAVA_HOME=/path/to/java8/java javaws qs.jnlp

To confirm the path to use, run "which -a java" (instead of "which --all java", because you've got a non-GNU version of which on your system).

Have I used the correct path and should I have cd Downloads where qs.jnlp is located

Hi Troysie
to solve your problem install icedtea-netx

Code:

 sudo apt-get install icedtea-netx

after run

Code:

javaws qs.jnlp

where is the qs.jnlp

After Java start IcedTes ad then Quotestream start, but same time have a problem when load the VM

Ciao
