STRUTS 2: File tag problem
Hello,
I am using file tag works fine if a file is selected using browse button or the path is entered manually. But if file name/path is rubbish the form is not submitted at all, nothing happens.
1. How do I control this - show error like invalid filename?
2. Or else how to disable manual entry, only browse button works???????
3. I tried javascript options like onKeypress to reset value to null - didnt help.
Please help.
Regards,
Srikanth

Hi Martin,
Thanks for the reply. I didnt quite get what you are trying to say. My code is exactly similar to the example you given except the implementation for method "public File getUpload()". In your example it return SUCCESS and ERROR which are strings but it should return File. I have only one line "return dc". Please help if I am missing something here.
I tried to give some logic to getFileName() and getDc() (=getUpload()) methods but the issue is still there, if crap is typed into file field - nothing happens when submit is clicked.
Regards,
Srikanth

Hi Sri
so if the config is configured something like
/WEB-INF/classes/struts-fileupload.xml
<action name="doUpload"
class="org.apache.struts2.showcase.fileupload.FileUploadAction"
method="upload">
<result name="success">uploadSuccess.jsp</result>
<result name="error">uploadError.jsp</result>
</action>
and the jsp defines the acceptable content-type and a name to call it..
<s:file name="upload" accept="text/*" />
org.apache.struts2.portlet.example.fileupload.FileUploadAction.java
{
private String fileName; //this is the FULL pathname with filename
// since we are using <s:file name="upload" .../> the file name will be
obtained through getter/setter of <file-tag-name>FileName
public String getUploadFileName()
{
return fileName;
}
public void setUploadFileName(String fileName)
{
this.fileName = fileName;
}
// since we are using <s:file name="upload" ... /> the File itself will
be obtained through getter/setter of <file-tag-name>
public File getUpload()
{
java.io.File file;
try
{ //try to create the file with the previously provided filename
file= new java.io.File( filename );
}
catch(java.lang.NullPointerException excp)
{
return ERROR;
}
if(file.canRead()) return SUCCESS;
else return ERROR;
}
public void setUpload(File upload)
{
this.upload = upload;
}
}
I didnt test with the templateDir attribute..

Unfortunately you don't have much control over it. Perhaps you could add
an onkeypress event listener that blocks typed input.

Depending on the browser this may or may not have the full pathname.
