Uploading a File fails with Vaadin Spring PLupload-Addon
Hi,
If i want to upload a file with a specific widget/addon of Vaadin, im getting some warnings and the files does not be uploaded.
I don't have any idea, why this warning occurres. I was checking the whole addon and saw some JavaScript usage, which using that POST but i don't get why it throwing some warnings and doesn't work at all.
I checked the Addon without Spring integration and everything worked well.
This are the warnings:
2015-08-16_15:44:53.777 WARN o.s.web.servlet.PageNotFound - Request method 'POST' not supported
2015-08-16_15:44:53.777 WARN o.s.w.s.m.s.DefaultHandlerExceptionResolver - Handler execution resulted in exception: Request method 'POST' not supported

My Code is the following, a simple init() with minimum of functionallity:
protected void init (VaadinRequest request){
HorizontalLayout root = new HorizontalLayout();
root.setSizeFull();
setContent(root);
setSizeFull();
PluploadManager manager = new PluploadManager();
manager.getUploader().setMaxFileSize("10mb");
manager.getUploader().addFileUploadedListener(new Plupload.FileUploadedListener() {
public void onFileUploaded(PluploadFile file) {
Notification.show("I've just uploaded file: " + file.getName());
}
});
manager.getUploader().addErrorListener(new Plupload.ErrorListener() {
public void onError(PluploadError error) {
Notification.show("There was an error: " + error.getMessage() + " (" + error.getType() + ")",
Notification.Type.ERROR_MESSAGE);
}
});
root.addComponent(manager);
}
Here are my dependencies inside the POM:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-spring-boot-starter</artifactId>
<version>1.0.0.beta3</version>
</dependency>
<dependency>
<groupId>pl.exsio</groupId>
<artifactId>plupload-vaadin</artifactId>
<version>2.0.0</version>
</dependency>
Current Technolgies:
- Java 1.8
- Vaadin 7.5.3
- Spring Boot 1.3.0.M3 ( https://start.spring.io/ )
- Maven POM
- Vaadin Widget / Addon: PLupload Wrapper : ( https://vaadin.com/directory#!addon/plupload-wrapper-for-vaadin-7x )
I had the same problem (spring-boot + vaadin + plupload add-on). I registered vaadin servlet again (it is a brute force method :) - I don't know how to overwrite servlet paths):
@Bean
ServletRegistrationBean reg(VaadinServlet s) {
ServletRegistrationBean r = new ServletRegistrationBean(s,"/vaadinServlet/*", "/VAADIN/*","/pluploader-upload-action"); return r;
}
I had to add handler in my UI.init():
VaadinSession.getCurrent().addRequestHandler(PluploadReceiver.getInstance());
And it works. :)
