无法将类导入JSP [英] Trouble importing classes to JSP
问题描述
凭借其智慧 jspc 告诉我以下关于我的一个 JSP s
In it's wisdom jspc told me the following about one of my JSPs
[ERROR] MyClassName cannot be resolved to a type
确实不存在..嗯..让我们把它包括在内！
Indeed it was not there.. Hmm .. Lets include it!
<%@ page import="com.a.b.c.MyClassName"%>
好的，现在 jspc 说
[ERROR] Only a type can be imported. com.a.b.c.MyClassName resolves to a package
这根本不是真的，但好吧，让我们尝试通配它
That's simply is not true, but ok, lets try wildcarding it
<%@ page import="com.a.b.c.*"%>
jspc 返回原始错误
[ERROR] MyClassName cannot be resolved to a type
任何想法？
确认：问题与构建时间隔离。在运行时，假设所有导入都如上所示完成，一切正常。
Confirmed: issue is isolated to the build time. At run time, assuming all imports are done as shown above, everything works.
推荐答案
在我的理解中 com.abcMyClassName 位于JSP无法访问的类加载器中。
In my understanding com.a.b.c.MyClassName is in a Class Loader not accessible by the JSP.
如果您有多个Web应用程序且JSP位于Web应用程序中而该类位于另一个应用程序中，则会发生这种情况。
This can happen if you have multiple web applications and the JSP is in a web app and the class in another.
测试只是将类放在app server全局类路径中。
To test that simply put the class in the app server global classpath.
