关于如何将jar添加到编译环境中的问题！

Question

不要急着编译, 先看看源代码有没有使用1.5有而1.4没有的特性, 如果有, 升级jdk吧.

Answer 1

用IDE.
jbuilder, jdeveloper, eclipse, 到处都能下,官方网都有免费下.打命令编译? 类库多起来, 整死人~

Answer 2

Jbuilder也可以到处都下吗？牛人就牛人，不怕“枪毙”。eclipse是倒是到处可以下

Answer 3

诸位，看来我没说清楚啊，实在是抱歉！
是这样的，在windows下，我是在window xp/eclipse/jdk1.5/tomcat下，编译运行测试都没问题！
但跑到aix/jdk1.4.2/WebSphere6.0下就出问题了！
首先是jdk1.42不支持1.5的一些新特性，那么好，我现在改了一些代码，在window下编译也都没问题了，实际上改动的地方很少！
其次，我发现最简单的东西你得拿到aix下重新进行编译才行，否则会抱错，错误提示来看，显然与websphere有关，因为是利用websphere自带的javac编译的，我想和J2EE容器有关吧？
我感觉现在的问题不是我的代码，这是没问题的，而是如何在aix下编译？
我甚至用JCREATOR 结合jdk1.4.2编译后放在aix下还是不行，看来真得在aix下编，但aix下没有什么IDE工具，难道说把eclipse放到aix下？可行吗？

亲爱的楼主， WAS6.1才支持JDK5.0 及 JSP2.0。
IF  你的页面中有用到JSP2.0的元素， 那么恭喜你可以升级WAS了
ELSE 貌似得配置一个复杂配置文件， 我们的项目里的给你看下，我贴上，呵呵~~--------------------------------------------------------
