Strange FileNotFoundException
while uploading file using Struts2. This is a part of JSP:
<a:form action="/FileUploadServletAction.action" method="post" enctype="multipart/form-data">
<a:file name="fileUpload" label="File"/>
<a:submit/>
This is the execute() method, to copy uploaded file from temporary location to actual location:
public String execute() throws Exception{
try {
String filePath = "c:/foo";
System.out.println("Server path:" + filePath);
File fileToCreate = new File(filePath, this.fileUploadContentType);
FileUtils.copyFile(this.fileUpload, fileToCreate);
} catch (Exception e) {
e.printStackTrace();
addActionError(e.getMessage());
return INPUT;
}
return SUCCESS;
}
This is my portion of struts.xml which configures above Action class:
<action name="FileUploadServletAction"
class="com.test.FileUploadServletAction">
<result name="input">/jsp/upload.jsp</result>
<result name="success">/jsp/upload.jsp</result>
<result name="error">/jsp/error.jsp</result>
</action>
But when I run I get this exception:
java.io.FileNotFoundException: Source 'E:\Foo\Projects\Foo\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\FooProject\upload_1ec6cc50_75d7_482f_83be_fe4185999973_00000000.tmp' does not exist
at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:1074)
at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:1038)
INFO: Removing file fileUpload E:\Foo\Projects\Foo\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\FooProject\upload_1ec6cc50_75d7_482f_83be_fe4185999973_00000000.tmp
Can anyone let me know why Struts is not able to find temporary file which is created? Please let me know if you need additional information.

I think you are missing getter and setter methods, I don't know have you defined or not?
JSP code:
<form action="FileUploadServletAction" method="post" enctype="multipart/form-data">
<label>File:</label><input type="file" name="userKey"/>
<input type="image" src="images/login-btn.jpg" alt="submit" width="103" height="42"/>
</form>
Action code:
//In FileUploadServletAction
private File userKey; //file name which is on JSP
private String userKeyContentType;
private String userKeyFileName;
//getter, setter
public File getUserKey()
{
return userKey;
}
public void setUserKey(File userKey)
{
this.userKey = userKey;
}
public String getUserKeyFileName()
{
return userKeyFileName;
}
public String getUserKeyContentType()
{
return userKeyContentType;
}
public void setUserKeyContentType(String userKeyContentType)
{
this.userKeyContentType = userKeyContentType;
}
public void setUserKeyFileName(String userKeyFileName)
{
this.userKeyFileName = userKeyFileName;
}
Now, execute()
method
//In FileUploadServletAction
public String execute() throws Exception{
try {
String filePath = request.getSession().getServletContext().getRealPath("/");
File fileToCreate = new File(filePath, this.userKeyFileName);
FileUtils.copyFile(this.userKey, fileToCreate);
} catch (Exception e) {
e.printStackTrace();
addActionError(e.getMessage());
return INPUT;
}
return SUCCESS;
}

try with inteceptor your action should like this..
<action name="FileUploadServletAction" class="com.test.FileUploadServletAction">
<interceptor-ref name="fileUpload">
<param name="maximunSize">1024000</param>
<param name="allowedTypes">
your types
</param>
</interceptor-ref>
<interceptor-ref name="defaultStack"></interceptor-ref>
<result name="input">/jsp/upload.jsp</result>
<result name="success">/jsp/upload.jsp</result>
<result name="error">/jsp/error.jsp</result>
</action>
