哪里有用myeclipse开发jsp+javabean+tomcat的例子?????在myeclipse中应该如何编译javabean
在网上找到一种说法:对于没有main函数的java源文件,eclipse的默认是自动编译的。
对于myeclipse也是一样吗?为何我的jsp+javabean结构的程序无法运行,而jsp文件可以运行呢???
错误提示如下:

的确JAVABEAN是自动编译的,出现上面问题可能是你的路径有问题.
10分也拿的出手啊!
不要用myeclipse了 ,不是源码开放的,用wtp吧,源码开放,挺好用的
用myeclipse跟你用eclipse的基本操作是一样,即使你装了myeclipse,一样可以使用eclipse,都是指向eclipse的执行文件,无非就是eclipse多了myeclipse的一个菜单
