Operating Systems Linux Fedora Fedora: Uninstall Java JDK 1.8 and install Oracle Java 1.7.15 Post 303009957 by Peasant on Friday 22nd of December 2017 11:59:23 PM

No need to uninstall anything.

Install the required oracle java using rpm.
Using alternatives command as superuser one can change the default java used.

Bare in mind, that perhaps some programs on the system rely on open java, so above change could affect those.

One could also download only required oracle java as compressed archive with all binaries and libraries required.
Create a user on the system which will utilize that java environment.
Unpack the archive under /opt/orajava (for instance)
As root, chown /opt/orajava to user created.
Setup required java options in user home directory profile file (JAVA_HOME etc.)
Configure kernel parameters for that user, depending on the application requirements/load (if applicable, defaults are often ok).

Above setup will have no effect on the system other then running new processes/code (load) under user created above and consuming disk space required.

Hope that helps
Regards
Peasant.

NAME
schemagen - Java(TM) Architecture for XML Binding Schema Generator Specification Version: 2.0 Reference Implementation (RI) Version: 2.0 ea3 Launching schemagen The schema generator can be launched using the appropriate schemagen shell script in the bin directory for your platform. The current schema generator can process either Java source files or class files. We also provide an Ant task to run the schema generator - see the instructions for using schemagen with Ant. For Solaris/Linux % path/to/jaxb/bin/schemagen.sh Foo.java Bar.java ... Note: Writing schema1.xsd For WindowsNT/2000/XP > path ojaxbinschemagen.bat Foo.java Bar.java ... Note: Writing schema1.xsd If your java sources/classes reference other classes, they must be accessable on your system CLASSPATH environment variable, or they need to be given to the tool by using the -classpath/-cp options. Otherwise you will see errors when generating your schema. Command Line Options Usage: schemagen [-options ...] <java files> Options: -d <path> : Specify where to place processor and javac generated class files -cp <path> : Specify where to find user specified files -classpath <path> : Specify where to find user specified files -help : Display this usage message Generated Resource Files The current schema generator simply creates a schema file for each namespace referenced in your Java classes. There is no way to control the name of the generated schema files at this time. For that purpose, use the schema generator ant task.
