我也尝试在命令行中使用“build war”,这产生了相同的结果.

这是我正在使用的JDK的问题还是还有其他我需要关注的问题？这是我第一次尝试构建和部署茧,我可能会遗漏一些明显的东西.

问候,托尼

解决方法

已弃用的专有com.sun.image.jpeg.codec软件包已从JDK 7中删除(请参阅此官方 official JDK7 compatibility note).因此你的编译问题.

由于在您的情况下修补Cocoon源可能不是一个选项,因此最短路径可能是使用JDK 6(或更早版本,the Cocoon 2.1 series require “Java 1.3 or later”)进行编译.

(但如果是,因为您似乎需要特定的Cocoon和JDK版本,您可能希望通过调用标准Java Image I / O API来查看How to replace com.sun.image.codec.jpeg.JPEGImageEncoder上的SO Q& A)

另一种选择可能是查看com.sun.image.jpeg.codec包的单独分发,以包含在构建(以及可能的运行时)类路径中.我不确定此选项的可用性(以及易用性).无论如何我不建议挖掘它,除非所有其他路径都被证明是死路一条……
