#tus_servlet
Java servlet implementing server side of the TUS Protocol 1.0.0

Quick Start

Build and launch a standalone server at http://localhost:8080

$ mvn jetty:run

Quick Upload

$ curl -X POST -I 'http://localhost:8080/files' \
               -H 'Tus-Resumable: 1.0.0' \
               -H 'Upload-Length: 12345678'

$ curl -X PATCH -I 'http://localhost:8080/files/70ede2c5_f139_4aeb_b2da_774149c68286' \
               -H 'Tus-Resumable: 1.0.0' \
               -H 'Upload-Offset: 0' \
               -H 'Content-Type: application/offset+octet-stream' \
               --upload-file path/to/file.mp4

Upload using a javascript client

# Get the client code
$ git clone  https://github.com/tus/tus-js-client
$ cd tus-js-client/demo
$ ls
demo.css	demo.js		index.html

Open index.html in a browser. In the form, set the upload endpoint to http://localhost:8080/files and use the Browse button to try out uploads. This servlet doesn't implement GET so downloads won't work.

Incorporate the Servlet in Your Application

# Build a jar containing the servlet
$ mvn package
# Install the jar in your local mvn repo
$ mvn install

Add the dependency to pom.xml

<!-- The tus_servlet itself: -->
<dependency>
    <groupId>org.tus</groupId>
    <artifactId>tus_servlet</artifactId>
    <version>0.1-SNAPSHOT</version>
</dependency>

Add the filter and servlet to web.xml

    <filter>
    	<filter-name>MethodOverrideFilter</filter-name>
        <filter-class>org.tus.filter.methodoverride.HttpMethodOverrideFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>MethodOverrideFilter</filter-name>
        <servlet-name>upload</servlet-name>
    </filter-mapping>

    <servlet>
        <servlet-name>upload</servlet-name>
        <servlet-class> org.tus.servlet.upload.Upload </servlet-class>
        <!-- More info about init-params below -->
		<init-param>
            <param-name>uploadFolder</param-name>
            <param-value>/tmp</param-value>
        </init-param>
        <init-param>
            <param-name>maxFileSize</param-name>
            <param-value>0</param-value>
        </init-param>
        <init-param>
            <param-name>maxStorage</param-name>
            <param-value>0</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>upload</servlet-name>
        <url-pattern>/files/*</url-pattern>
    </servlet-mapping>

If using the servlet in a struts app, you'll need to configure struts.xml to ignore the path that this servlet is handling. For example:

<constant name="struts.action.excludePattern" value="/files,/files/[0-9a-zA-Z_]*"/>

Configuration (web.xml init-param)

• uploadFolder - Absolute pathname of the directory to which files will be uploaded. Directory must already exist.
• maxFileSize - Maxiumum number of bytes allowed for a single file. 0 means unlimited.
• maxStorage - Maximum number of bytes this servlet will use for uploaded files. 0 means unlimited. NOT IMPLEMENTED.
• maxRequest - Maximum number of bytes server will accept in a single patch request. 0 means unlimited.
