本文介绍了如何建立使用Apache Ant的一个OpenLaszlo的DHTML应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我读过有关OpenLaszlo的 lzdeploy工具，但似乎只有很少的文档。
I've read about OpenLaszlo's lzdeploy tool, but there seems to be only little documentation available.
应该是可以构建采用Apache Ant的DHTML的OpenLaszlo应用程序（例如，作为一个自动生成过程的一部分）。如何才能LZC和lzdeploy工具使用了蚂蚁的生成OpenLaszlo应用程序的DHTML运行时的编译版本，包括包装页面？
It should be possible to build an OpenLaszlo DHTML application using Apache Ant (e.g. as part of an automated build process). How can the lzc and lzdeploy tool be used out of Ant to generate a compiled version of an OpenLaszlo application for the DHTML runtime, including the wrapper page?
推荐答案
下面是一个完整的Ant构建脚本，你可以用OpenLaszlo 5.0使用（没有与旧版本测试）。
Here is a full Ant build script which you can use with OpenLaszlo 5.0 (haven't tested with older versions).

把构建脚本到名为testapp $ LPS_HOME（OpenLaszlo服务器HOME）下的子目录。创建一个子目录LZX，一个名为testapp.lzx一个帆布的OpenLaszlo应用程序。我已经添加了一个图像资源到子文件夹中的资源来测试，如果资源被正确地打包到SOLO编译的应用程序文件夹中。
Put the build script into a subfolder of $LPS_HOME (OpenLaszlo server home) called testapp. Create a subdirectory LZX, with an OpenLaszlo canvas application called testapp.lzx. I've added an image resource into the subfolder resources to test if resources are packaged correctly into the SOLO compiled application folders.
$LPS_HOME
└── testapp
├── build.xml
└── lzx
├── resources
│ └── Winnie-the-Pooh.jpg
└── testapp.lzx
坐进$ LPS_HOME，并运行Ant构建。编译过程应该贯穿，你应该得到的文件夹结构：
Got into $LPS_HOME, and run "ant build". The build process should run through, and you should have the resulting folder structure:
testapp
├── build
│ └── tmp
│ ├── lzdeploy (more files)
│ └── lzxcompile (more files)
├── build.xml
├── lzx
│ ├── resources
│ │ └── Winnie-the-Pooh.jpg
│ └── testapp.lzx
└── release
├── dhtml
│ ├── index.html
│ ├── lps (more files)
│ ├── resources
│ │ └── Winnie-the-Pooh.jpg
│ ├── testapp.20120810-125652.lzx.js
│ └── testapp.20120810-125652.sprite.png
├── dhtml-debug
│ ├── index.html
│ ├── lps (more files)
│ ├── resources
│ │ └── Winnie-the-Pooh.jpg
│ ├── testapp.20120810-125652.lzx.js

└── swf10-debug
├── index.html
└── lps (more files)
在创建过程中产生的OpenLaszlo的应用程序的三个版本：SWF与调试，使用和不使用调试模式中启用DHTML / HTML5。所有的JavaScript和SWF文件具有附加一个时间戳，这意味着应用程序的新版本将不会从浏览器缓存中抽取。如果将浏览器指向发布的文件夹，点击任何的三个文件夹（SWF10调试，DHTML，DHTML调试）应开启SOLO编译应用程序。
The build process has generated three versions of the OpenLaszlo app: SWF with debug, DHTML/HTML5 with and without debug mode enabled. All JavaScript and SWF files have a timestamp attached, which means a new version of the application will not be pulled from the browser cache. If point your browser to the release folder, clicking on any of the three folders (swf10-debug, dhtml, dhtml-debug) should open the SOLO compiled app.
添加自己的脚本上传发布Web服务器，这应该不是什么难事。
Add your own scripts to upload the release to a webserver, that should not be difficult.
