While uploading file using struts2, need to follow naming conventions to get the filecontent type and file name.

Here is notation

File upoload
String uploadFileName
String uploadContentType

and associated getter and setter methods.

Thanks

Hi i need to get a properties file on application load up in my login jsp. Currently I am using request.getRealPath for this. But this is a dprecated method. However when the application is in expanded form, it seems to work just fine. But when I create a WAR file. The application is unable to get the path and thus unable to read the file. The application thus crashes at the very begining itself when deployed using a war file. How can it be resolved?

Also, currently it throws exception that request was not valid, i am on edit page, so in that case i loose all the details that was there & the empty form comes :(.

i want to uploading code in struts1.2 .i want cv send the database in struts1.2

Posted by sudhir on Sunday, 04.12.09 @ 18:35pm | #86745

I'm trying to do upload a file using struts2 file tag. Followed all the mentioned as given in http://struts.apache.org/2.0.11/docs/file-upload-interceptor.html. but still am not able to retreive the file contents in my action class. Below is the code snippet which i added.
ApplicationResources.properties
struts.messages.error.uploading=a general error that occurs when the file could not be uploaded
struts.messages.error.file.too.large=occurs when the uploaded file is too large
struts.messages.error.content.type.not.allowed=occurs when the uploaded file does not match the expected content types specified

Struts.xml
<interceptors>
<interceptor name="servletConfig" class="org.apache.struts2.interceptor.ServletConfigInterceptor"/>
<interceptor name="fileUpload" class="org.apache.struts2.interceptor.FileUploadInterceptor"/>
<interceptor-stack name="basicStack">
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="fileUpload"/>
</interceptor-stack>
</interceptors>

<action name="uploadFile" method="uploadFile" class="com.example.MyAction">
<interceptor-ref name="fileUpload"/>
<exception-mapping exception="java.lang.Exception" result="error"/>
<result name="success">/jsp/success.jsp</result>
</action>

MyAction.java
import java.io.File;
//The below properties with getter and setter methods defined
private File subUploadFile; // The actual file
private String uploadContentType; // The content type of the file
private String uploadFileName; // The uploaded file name and path

public String uploadFile() throws Exception {
System.out.println("Inside uploadFile() .....");
System.out.println("File : " + getSubUploadFile());
System.out.println("File Name : " + getUploadFileName());
System.out.println("Content type : " + getUploadContentType());
return SUCCESS;
}


myForm.jsp
<s:form action="goSubRegn" method="POST" enctype="multipart/form-data">
<s:file size="110" name="subUploadFile"/>

All the S.O.P. are printing null

file upload send in database in struts1.2

Posted by sudhir on Thursday, 04.9.09 @ 13:36pm | #86679

I have the same issue as nutbag:
>>How do you set up a validator to make sure the user's file selection is valid? I've tried 'required' and an expression validator but none of them seem to catch it.

nutbag: did you figure this out? Does anyone know how?

Posted by rumblefish on Wednesday, 01.21.09 @ 15:37pm | #84027

Thanks. The tutorial was very useful and I had a basic file upload up and running in no time.

One very important piece of missing information however: you need to include the commons-filupload-1.2.jar and commons-io.1.3.1.jar files otherwise it won't work. This will fix the issue that people are having with "Unable to load bean org.apache.struts2.dispatcher.multipart.MultiPartRequest" errors.

Other useful items. In order to change where the files get downloaded to, add a line to your struts.properties file. For example:

struts.multipart.saveDir=/tmp/uploader

Finally, the file is deleted once the operation finished. In order to store it add some code to the "execute" method. For example:

public String execute() throws Exception {

File outFile = new File("/tmp/newfilename");
InputStream inStrm = new FileInputStream(getUpload());
OutputStream outStrm = new FileOutputStream(outFile);

// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = inStrm.read(buf)) > 0) {
outStrm.write(buf, 0, len);
}
inStrm.close();
outStrm.close();

return SUCCESS;
}

Can i have the solution for this with an example please?

why File Upload Interceptor deletes file and how to escape from it because for me this does not makes any sense that file gets deleted automatically then what is the point of uploading it..

Unable to load bean org.apache.struts2.dispatcher.multipart.MultiPartRequest (jakarta) - [unknown location]

Hi friends.....
i tried uploading all type of files....
now i want to upload only pictures of jpeg format......
Can u suggest me a solution?

Posted by srinadh on Wednesday, 02.20.08 @ 12:09pm | #49186

If you want to upload files bigger than 2mb in your struts.properties file, you must set this attribute

struts.multipart.maxSize

This value defaults to 2mb, if you want your fileupload interceptor to to manage max file size you must set this value to be larger than the interceptor setting.

And if you don't know... here is how you set it from the interceptor

<interceptor-ref name="fileUpload">
<param name="maximumSize" >1024</param>
<param name="allowedTypes">image/png,image/gif,image/jpeg,image/jpg</param>
</interceptor-ref>

Just put those lines inside of your action definition in your struts.xml.


Posted by trevis on Tuesday, 02.19.08 @ 22:32pm | #49113

As was said below, you need to download commons-fileupload and commons-io and add them to your lib folder.

But for it to work you also need to have a struts.properties file and add this line to it:

struts.multipart.parser=org.apache.struts2.dispatcher.multipart.JakartaMultiPartRequest

Hi, I have a page with 2 submit buttons: one to upload the file and one to view the file. The "view button" reload the page to update a table. My problem is that when I reload the page, the path of the selected file isn't visible anymore and I think is a little confuse to the user.

Can you give some me help with this?

How do you set up a validator to make sure the user's file selection is valid? I've tried 'required' and an expression validator but none of them seem to catch it.

Posted by nutbag on Thursday, 08.2.07 @ 08:23am | #22466

The file upload does not work unless you obtain commons-fileupload and commons-io and place them in the web-inf/lib folder of the tutorial.
