How to run an application on a specific Java version?
提问by Socrates
How can I run an application with a specific Java version? I have three Java versions intstalled:
如何运行具有特定 Java 版本的应用程序？我安装了三个 Java 版本：
myuser@mysystem:~$ sudo update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 auto mode
* 1 /opt/jdk-9.0.4/bin/java 1 manual mode
2 /opt/jdk1.8.0_162/bin/java 1 manual mode
3 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode
I have Java 9 set as default and I'd like to keep it that way. Still, an application named pdfsamdoesn't seem to work properly with Java 9. What command is necessary to run it with openjdk (option 3)?
我将 Java 9 设置为默认值，我想保持这种状态。尽管如此，名为的应用程序pdfsam似乎无法在 Java 9 中正常工作。使用 openjdk（选项 3）运行它需要什么命令？

You can run javawith the absolute path to the installation
您可以java使用安装的绝对路径运行
This would be your default /usr/bin/javainstallation
这将是您的默认/usr/bin/java安装
java -version
To change it, use the absolute path
要更改它，请使用绝对路径
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -version
If you're not running the javacommand directly, try setting the JAVA_HOME variable:
如果您没有java直接运行该命令，请尝试设置 JAVA_HOME 变量：
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/" pdfsam
