    public String uploadImageTest(@RequestParam("demoImage") MultipartFile file) throws IllegalStateException, IOException {
        try {
            String fileName = null;
            InputStream inputStream = null;
            OutputStream outputStream = null;
            if (file.getSize() > 0) {
                inputStream = file.getInputStream();

                System.out.println("File Size:::" + file.getSize());

                System.out.println("size::" + file.getSize());
                fileName = request.getServletContext().getRealPath("/resources/") + "/css/"
                        + file.getOriginalFilename();
                outputStream = new FileOutputStream(fileName);
                System.out.println("fileName:" + file.getOriginalFilename());
                int readBytes = 0;
                byte[] buffer = new byte[10000];
                while ((readBytes = inputStream.read(buffer, 0, 10000)) != -1) {
                    outputStream.write(buffer, 0, readBytes);
                }
                outputStream.close();
                inputStream.close();
            }

Answer 1

The location you want to save the file is invalid, as it is in fact, inside your WAR file, which gets exploded into the JBoss temp directory, hence you see the .../tmp/vfs/deployment.... folder.

However, you can specify a particular location for your default multi-part upload location, in multiple ways.

1. If you are using Servlet 3.0, you configure multipart servlet, either as annotation or in web.xml. You can annotate a pure servlet, in the following way.

@WebServlet("/myImageFileUploader")
@MultipartConfig(location = "/opt/myImageFileUploadLocation")
public class MyImageFileUploaderServlet extends HttpServlet {
.....}

XML configuration is as below

  <servlet>
    <servlet-name>MySpringDispatcher1</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:/spring-servlet.xml</param-value>
    </init-param>
    <multipart-config>
        <location>/opt/myImageFileUploadLocation</location>
        <max-file-size>52428800</max-file-size>
        <max-request-size>52428800</max-request-size>
        <file-size-threshold>0</file-size-threshold>
    </multipart-config>
</servlet>

The above XML example can be used directly in your project, if you are using Servlet 3.0. The sample code is configuring the Spring DispatcherServlet, for your convenience. JBoss 7 Web has Servlet 3.0, by default, so I guess it will work.

2. If your Servlet version is pre 3.0, I mean, older versions, then you can configure commons-fileupload in the spring configuration file, as given below.

<bean id="myImageMultipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  <property name="maxUploadSize" value="100000" />
  <property name="uploadTempDir" ref="myImageFileUploadDirResource" />
</bean>

<bean id="myImageFileUploadDirResource" class="org.springframework.core.io.FileSystemResource">
  <constructor-arg>
  <value>/opt/myImageFileUploadLocation</value>
  </constructor-arg>
</bean>

Hope this helps.
