我刚刚在SUSE框中设置了JasperReports服务器，我无法通过tomcat实际提供任何页面。 webapp被列为在tomcat管理器上运行，但连接到它会给出一个不错的小404：
type Status report
message /jasperserver/portal/homepage
description The requested resource is not available.
查看Localhost.log文件，我遇到了这些错误：

<display-name>JasperReports Server</display-name>
<description>
This is version X.X of an application to perform
a wild and wonderful task, based on servlets and
JSP pages. It was written by Dave Developer
(dave@mycompany.com), who should be contacted for
more information.

<!-- Context initialization parameters that define shared
String constants used within your application, which
can be customized by the system administrator who is
installing your application. The values actually
assigned to these parameters can be retrieved in a
servlet or JSP page by calling:
String value =
getServletContext().getInitParameter("name");
where "name" matches the <param-name> element of
one of these initialization parameters.
You can define any number of context initialization
parameters, including zero.

<!-- Servlet definitions for the servlets that make up
your web application, including initialization
parameters. With Tomcat, you can also send requests
to servlets not listed here with a request like this:
http://localhost:8080/{context-path}/servlet/{classname}
but this usage is not guaranteed to be portable. It also
makes relative references to images and other resources
required by your servlet more complicated, so defining
all of your servlets (and defining a mapping to them with
a servlet-mapping element) is recommended.
Servlet initialization parameters can be retrieved in a
servlet or JSP page by calling:
String value =
getServletConfig().getInitParameter("name");
where "name" matches the <param-name> element of
one of these initialization parameters.
You can define any number of servlets, including zero.

<servlet>
<servlet-name>controller</servlet-name>
<description>
This servlet plays the "controller" role in the MVC architecture
used in this application. It is generally mapped to the ".do"
filename extension with a servlet-mapping element, and all form
submits in the app will be submitted to a request URI like
"saveCustomer.do", which will therefore be mapped to this servlet.
The initialization parameter names for this servlet are the
"servlet path" that will be received by this servlet (after the
filename extension is removed). The corresponding value is the
name of the action class that will be used to process this request.

<servlet>

<description>
This servlet produces GIF images that are dynamically generated
graphs, based on the input parameters included on the request.
It is generally mapped to a specific request URI like "/graph".
</description>
</servlet>
<!-- Define mappings that are used by the servlet container to
translate a particular request URI (context-relative) to a
particular servlet. The examples below correspond to the
servlet descriptions above. Thus, a request URI like:
http://localhost:8080/{contextpath}/graph
will be mapped to the "graph" servlet, while a request like:
http://localhost:8080/{contextpath}/saveCustomer.do
will be mapped to the "controller" servlet.
You may define any number of servlet mappings, including zero.
It is also legal to define more than one mapping for the same
servlet, if you wish to.

似乎告诉我，我应该在/ opt / bonita / webapps / jasperserver / WEB-INF / classes / com / mycompany / mypackage中有一个名为ControllerServlet.class的文件。我的classes文件夹中甚至没有名为com的文件夹，在我的classes文件夹中没有名为controller或controllerservlet的类。我是否需要在某处重定向或找到控制器文件？
同一个tomcat服务器上的其他webapp正常运行。
你们对我这个跑步有什么建议吗？谢谢！
