I am currently trying to implement asynchronous file uploading using a Servlet in a MVC portlet in Liferay 7 and I'm running into issues configuring the servlet. I've tried looking around the internet for an answer but currently there doesn't seem to be much out there about Liferay 7 and servlets. The need for a servlet comes from the fact that we would like to be able to have users upload multiple files asynchronously without requiring a page refresh.
Here is my current attempt at implementing the servlet:
MVC portlet class:
@Component(
immediate = true,
property = {
"com.liferay.portlet.display-category=category.sample",
"com.liferay.portlet.instanceable=true",
"javax.portlet.display-name=audit-view Portlet",
"javax.portlet.init-param.template-path=/",
"javax.portlet.init-param.view-template=/view.jsp",
"javax.portlet.resource-bundle=content.Language",
"javax.portlet.security-role-ref=power-user,user"
},
service = Portlet.class
)
public class AuditViewPortlet extends MVCPortlet {
}
web.xml: (placed in the file path src/main/resources/WEB-INF/web.xml)
<!--?xml version="1.0" encoding="UTF-8"?-->
<web-app id="WebApp_ID" version="2.5" 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_2_5.xsd">
<display-name>audit-view Portlet</display-name>
<servlet>
<servlet-name>DocumentUpload</servlet-name>
<servlet-class>com.echelon.vm.servlet.DocumentUpload</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DocumentUpload</servlet-name>
<url-pattern>/documentUpload</url-pattern>
</servlet-mapping>
</web-app>
DocumentUpload Servlet:
package com.echelon.vm.servlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class DocumentUpload extends HttpServlet{
/**
*
*/
private static final long serialVersionUID = 1488294707145038780L;
@Override
public void doGet(HttpServletRequest request, HttpServletResponse response){
System.out.println("Hello");
}
}
I am currently trying to access the servlet by hitting the URL "localhost:8080/o/auditview/documentUpload", and I am getting the following error on my console: "[http-nio-8080-exec-2][code_jsp:181] {code="404", msg="ProxyServlet: /o/auditview/documentUpload", uri=/o/auditview/documentUpload}" My expected response is "Hello" being logged to the console.
However, if I go to the URL "localhost:8080/o/auditview" I get a HTTP 200 with no content displayed. I got the "/o/auditview" as the url for the portlet by adding the following code to the init.jsp of the portlet:
<aui:script>
console.log("${pageContext.request.contextPath}");
</aui:script>
If anyone could explain where I'm going wrong I'd greatly appreciate it.
