Java expiry information

Hi,

Code:
I have a requirement to check the expiry date of Java software installed in  linux servers.

We are using the below Java

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

I am not sure whether we can get that but after few research what  found is

a. Go to <java_home>\bin
b. Run jarsigner -verify -verbose -certs <jarfilename>.jar 

As per the above steps gave
echo $JAVA_HOME which resulted in 
/usr/lib/jvm/java



The problem is there are no .jar file in  the above path.Is there a way to get the expiry date, if so how to get.

Thanks in advance.

NAME
Maven - Installs a jar into /usr/share/maven-repo. SYNOPSIS
mh_installjar [option]... [pom] [jar] [link]... DESCRIPTION
Installs the jar file in /usr/share/maven-repo, at the correct location for Maven. The jar is copied into the build directory. It can also create additional links to the jar, usually located in /usr/share/java. Where [pom] is the location of the POM associated with the jar to install. GroupId, artifactId and version will be extracted from this file. [jar] is the path to the jar to install, usually located in the build folder. [link] is an additional link to the jar to install, usually there should be a link to usr/share/java/$jar.jar and usr/share/java/$jar-$version.jar to comply with the Java packaging guidelines. Note that there is no need to specify those particular links if the --java-lib option is used. OPTIONS
-h --help: show this text -V --version: show the version -p<package> --package=<package>: name of the Debian package which will contain this jar file -e<version>, --set-version=<version>: set the version for the jar, do not use the version declared in the POM file. -r<rules> --rules=<rules>: path to the file containing the rules to apply when cleaning the POM. Optional, the default location is debian/maven.rules Maven rules are used here to extract the groupId, artifactId and version from the POM file. -l --java-lib: Optional, if given it will install the jar into /usr/share/java to comply with the Debian Java specification. The jar will be installed as /usr/share/java/$name-$version.jar and a versionless link /usr/share/java/$name.jar will point to it, as well as the links installed in /usr/share/maven-repo -n<name> --usj-name=<name>: Optional, the name to use when installing the library in /usr/share/java when --java-lib is used. Defaults to the artifact id found in the POM. -j<version> --usj-version=<version>: Optional, the version to use when installing the library in /usr/share/java when --java-lib is used. Defaults to the version found in the POM. -s --no-usj-versionless: Optional, don't install the versionless link in /usr/share/java. This flag is used only when the -l or --java-lib option is given. -d<path> --dest-jar=<path>: Optional, the destination for the real jar. The other places where the jar appears, in the repository or in the list of links, will be symlinks to this jar. Defaults to /usr/share/java/$name-$version.jar if --java-lib is used, otherwise the jar is installed in the versioned path in the Maven reposi- tory. -c<classifier> --classifier=<classifier>: Optional, the classifier for the jar. Empty by default. -v --verbose: show more information while running -n --no-act: don't actually do anything, just print the results --skip-clean-pom: don't clean the pom, assume that a previous action ran mh_cleanpom with the correct options. mh_cleanpom is run only to extract the groupId, artifactId and version of the jar See also: mh_installpom(1), mh_installsite(1) Maven Repo Helper version 1.7.1 January 2012 MAVEN(1)
