我安装之后，他提示我选择一个jre。
但是列表里面一个东西都没有。
我明明装好了jdk1.4。
他还有一个boswer的给我指定目录，但是我该指定到哪里去呢，指到jdk的目录他又说没有。

ITPUB推荐文章解答你所有技术难题Excelsior JET - Java Virtual Machine (JVM) and Native Code Compiler
AOT Compilation Is Coming to Java 8. .
Excelsior JET enables you to distribute and&deploy your Java& applications
as&optimized native executables that&start and&work faster, do&not&depend on&the&JRE,
and&are as&difficult to&reverse engineer as&if&they were written in&C++.
What Is It?
Excelsior JET is a complete implementation of the Java SE 7 technology for Microsoft&Windows, Apple&OS&X, and&Linux. It&includes:
Java SE 7 compatible JVM
Ahead‑Of‑Time (AOT)Java to&native code compiler
Standard Java&SE&7 library, licensed&from&Oracle
Deployment toolkit
Version 11, available for ,
will ship in&September&2015 with Java&SE&8 and&JavaFX&8 support.
Excelsior JET has passed the official compliance tests (JCK) and is certified Java&Compatible.
How It Works
First, the AOT compiler turns your jar and class files into&a&conventional
binary executable. That executable is fully interoperable with our JVM,
which includes a&JIT compiler to&handle any classes that were not
precompiled.
Second, the deployment toolkit helps you create
an installer containing the application executable, necessary runtime files,
and&the auxiliary files of&your choice & data files,
documentation, license, etc.
You may be wondering what it takes to get this little
Java Compatible logo and, more importantly,
what benefits it delivers to you as a user of our product.
These are the key points:
Excelsior JET has
passed the Java&SE&7 Technology Compatibility Kit (JCK) test suite.
The JCK comprises over 200,000 individual
test cases verifying compliance with all aspects of the Java
specification. Technically, this means that any program coded
in accordance with the Java specification must produce the same
result on the
and when natively compiled with Excelsior JET.
The standard
Java SE class library included in Excelsior JET
is built from the same source code as the one included in the Oracle JRE.
The reuse of the reference implementation source code
not only has helped our product pass the JCK tests.
It also makes Excelsior JET replicate any loosely specified or
implementation-defined behavior of the standard Java library
classes as implemented in the Oracle JRE automatically.
The JCK is not a stress test.
It does not benchmark the implementation's performance or throughput.
Protection Against Java Decompilers Peace of mind
Java class files are easy to reverse-engineer. The very properties
that enable Java applications to run anywhere make reverse translation
straightforward. There are a number of Java decompilers on the market
that produce amazingly readable source code.
In contrast, reverse translation of optimized native code is
a&hard engineering task that cannot be automated like Java bytecode
decompilation.
can make the decompiled code less comprehensible.
However, name obfuscation may cause reflection and JNI failures,
whereas extensive control flow obfuscation negatively impacts performance
and may provoke a VerifyError. To make things worse,
these problems only manifest themselves when the respective
class is actually loaded at application run time, and thus may slip through
the QA process.
And reverse engineering of an equivalent C++ program passed through an
optimizing compiler would still be more difficult.
Excelsior JET gives you the best of both worlds. With it,
you reduce the set of class and jar files comprising your Java application
to a solid binary executable before shipping it to customers or
delpoying it to production servers.
You avoid the obfuscation trade-offs: reduced performance
and increased risk of run-time errors.
You may continue using tools that encrypt strings and resources,
and you may pass classes not accessed via
JNI or reflection through a name obfuscator
if you know what you are doing.
Improved User Experience Faster startup, smaller footprint, no dependencies
All charts represent data gathered by running particular applications in&specific environments.
Your mileage will&vary.
Natively precompiled Java code runs directly on hardware right from the start.
The absence of the warm-up cycle and JIT compilation overhead
results in faster application startup and optimal code performance.
Excelsior JET keeps the size of the Java SE runtime as small as possible,
reducing the download size and disk footprint of Java applications.
The unique
feature enables you to selectively omit
parts of the Java SE standard library that are not used by your application.
The run time memory footprint is also somewhat smaller because
the Excelsior JET JVM is leaner compared to traditional implementations.
Finally, the applications precompiled with Excelsior JET
do&not require the&JRE, and the included deployment tools
help you package your optimized application together with&the necessary
runtime files into a naitve installer.
