问题
I can open myApp throw Internet Browser if I start it via Eclipse, but, although I can start the Embedded server throw command line (java -jar myApp.jar) I am getting HTTP Status 404. Probably some issue with context but I can't figure out what is wrong.
Kindly, see below the structure in Eclipse and in myApp.jar. The application is basically compound by 5 files: two placed in com.mycompany.myapp.batchs.AuthFileUpload (App.class with main method and FileUploadController.class as a very simple controller). Other three files, App-servlet.xml, web.xml and index.jsp placed in WEB-INF.
Other possible reason can be I should point straigh to the classes in "tomcat.addWebapp("/", "the_place_where_classes_can_be_found_in_myApp.jar)". If so, how can I do it?
Index.jsp and the FileUploadController.java are too simple so it is pointless show both here.
App class
public static void main(String[] args) throws IOException,
ServletException, LifecycleException {
Tomcat tomcat = new Tomcat();
tomcat.setPort(8080);
tomcat.setBaseDir("C:\\temp\\");
tomcat.addWebapp("/", "C:\\temp\\");
tomcat.start();
tomcat.getServer().await();
}
App-servlet.xml
<context:component-scan base-package="com.mycompany.myapp.batchs.AuthFileUpload" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/" />
<property name="suffix" value=".jsp" />
</bean>
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

回答1:
Your app structure is wrong. Maven jar projects do not have a src/main/webapp folder.
On the other hand, in order to the container (not the classloader) finding the web resources (index.jsp) of your application in a jar, you must declare in web.xml that it is a servlet 3.0 webapp and place the resources in src/main/resources/META-INF/resources. See here for more details.
Try this:
Ensure webapp is servlet 3.0 and index.jsp is a welcome-file
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> ... </web-app>Refactor the structure to:
|-- src/main/resources | |-- WEB-INF/App-servlet.xml | |-- META-INF/resources | | | -- WEB-INF/web.xml | | | -- index.jsp
