exe4j可用于将jar包制作成Windows可执行程序，按该软件自己的说法，它是一个“Windows launcher generator”
下载地址：http://www.ej-technologies.com/download/exe4j/files
注意1：exe4j需要许可证号（lisense key）才能正常使用，install4j工具的许可证号同样适用于exe4j，该工具也支持使用独立的许可。如果你没有许可证号，exe4j仍可以无限次使用，但生成的可执行程序会展示评估版警告，生成的服务会在30分钟后自动停止。
注意2：exe4j的向导和编译器要求JRE版本达到1.7以上，生成的可执行程序要求JRE达到1.6以上即可。
目前最新的版本是exe4j 5.1，下载到本地后，是一个exe安装包
双击此安装包，进入安装向导
第一步：欢迎页面
第二步：许可协议（全文见本文最后的附录）
第三步：选择安装路径，这里我选择了E:\exe4j
第四步：在开始菜单建立快捷方式，我还勾选了下方的“为所有用户创建快捷方式”
第五步：建立文件扩展名的关联，如勾选了下图中的复选框，*.exe4j格式文件将会用exe4j程序进行打开
第六步：读条界面，释放资源
第七步：安装成功，可立即运行exe4j
exe4j工具exe4j.exe可以在开始菜单中找到，也可以在exe4j安装路径下的bin目录中找到。运行后的exe4j效果如下：
关于exe4j的具体使用方式，将另开博文详述。

5. Restrictions
You may not use, copy, or distribute the Software Product, except as granted by this EULA, without written authorization from ej-technologies.

The Software Product is not fault-tolerant and is not designed, manufactured or intended for use or resale as on-line control equipment in hazardous environments requiring fail-safe performance, in which the failure of the Software Product, or any software, tool, process, or service that was developed using the Software Product, could lead directly to death, personal injury, or severe physical or environmental damage ("High Risk Activities"). Accordingly, ej-technologies and its suppliers and licensors specifically disclaim any express or implied warranty of fitness for High Risk Activities. You agree that ej-technologies and its suppliers and licensors will not be liable for any claims or damages arising from the use of the Software Product, or any software, tool, process, or service that was developed using the Software Product, in such applications.

ej-technologies is fully liable in case of intention, gross negligence, loss from physical injury, severe organizational failure or in case of an acceptance of guarantee.
Liability for slight negligence is limited to material breach of contractual obligations and in that case to the typically predictable loss. Any further liability is excluded. Contributory negligence of the licensee and other parties will be taken into account. Any liability under the terms of product liability laws remains unaffected.
You agree to ensure that a data backup is performed on all computers that the Software Product or redistributable parts of it are used on. In case of loss of data, liability is limited to the cost that would arise in the case where a proper backup has been performed.
The limitation period is one year, if not otherwise regulated by law, and starts with the service provision.
Any limitation of ej-technologies' liability also applies to your staff, agents and associated companies.
8. General
ej-technologies may terminate this EULA if you fail to comply with any term or condition of this EULA. In such event, you must destroy all copies of the Software Product and Software Product Licenses.
This EULA is governed by the laws of Germany. Exclusive jurisdiction and place of performance is Muenchen, Germany, as long as permitted by applicable law. The United Nations Convention for the International Sale of Goods shall not apply.

All rights not expressly granted in this agreement are retained by ej-technologies.
