Question

At the moment, after uploading a file, the tmp file that gets created gets stored in:

\Apache Software Foundation\Apache Tomcat
7.0.22\work\Catalina\localhost\Project\upload__78a0adab_1380z353bfa__7gfe_00000000.tmp

How do I store it in my own custom directory? I’ve tried:

<param name="saveDir">/tmp</param>

But it still goes to the one I mentioned above.

EDIT 1 – struts.xml:

<action name="file_save" method="fileSave" class="FileActionBean">
            <interceptor-ref name="fileUpload">
                <param name="maximumSize">2097152</param>
                <param name="saveDir">/tmp</param>
                <param name="allowedTypes">
                    image/bmp,image/gif,image/jpeg,image/jpg,image/png
                </param>
            </interceptor-ref>
            <interceptor-ref name="defaultStack"></interceptor-ref>
            <result type="redirect">file</result>
        </action>

EDIT 2:

I am using struts 2 version 2.1.8.1

Answer 1

Are you using Spring?
In that case you can configure your ActionBean with your desired upload-directory.
Just add to your action-bean:

private String uploadDir;
public void setUploadDir(String uploadDir){
    this.uploadDir = uploadDir;
}

And modify your spring config applicationContext.xml to set the uploadDir. You can to it by setting value direct, or more preferably, by configfile as shown below:

<bean id="fileAction" class="FileActionBean" scope="prototype">
    <property name="uploadDir" value="${uploaddir}" />
</bean>

Update:

It is pretty easy to control where you want the file to be saved.
If the first character of your path string is not /, it will be relative to your “current” directory.
So you dont really need any “root” path if you want to save it in the webapp directory. Just plain simply: File file = new File("results.txt");

Or if you want to store it somewhere else than your current directory you can either navigate using ../../something or by just typing out the whole structure to where you want like: File file = new File("/home/something/something/myFile.txt");

Or in an windows environment you could try File file = new File("Z:\\results\\results.txt");


But it is not really a good idea to put your uploaded files in the same directory as the webapp. Then you will lose all your files every time you redeploy.
