package apache.commons not exists

[deep raj]

import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.*;

but when i compile this file it says
package org.apache.commons.fileupload does not exist

classpath=C:\Program Files\Java\jdk1.6.0\lib\tools.jar;C:\Program Files\Java\jre1.6.0\lib\j2ee.jar;F:\SOFT\Tomcat 5.0\common\lib\servlet-api.jar;F:\SOFT\Tomcat 5.0\common\lib\commons-fileupload-1.0.jar;


commons-fileupload-1.0.jar file is in two folders
1. F:\SOFT\Tomcat 5.0\common\lib
2. C:\Program Files\Java\jre1.6.0\lib\ext

I think since the package exists in both the folders the folder that is first accessed by the compiler is that of the Windows program files or in your given list the second one
so what the compiler does is that it first finds in this package it fails to get the required pacakage
For the solution just remove the package from the program files and see what happens.....

[deep raj]

means remove commons- fileupload-1.0.jar file from C:\Program Files\Java\jre1.6.0\lib\ext folder
are you telling this ?

Remove it from both places and deploy it with your application.

You need to have this jar in WEB-INF/lib of your webapp once your servlet gets complied.

However for compiling your servlet you just need to have this jar in your classpath.

Try explicitly putting this jar in your classpath while compliling

e.g java -cp %CLASSPATH%;F:\SOFT\Tomcat 5.0\common\lib\commons-fileupload-1.0.jar;. <your servlet class name>

[deep raj]

okay i did it what you said
now it shows
org.apache.commons.fileupload.servlet
org.apache.commons.fileupload.disk
packages not exists

[David Newton]

"It" what? Did you change your compilation classpath?

[deep raj]

yes

[Devaka Cooray]

Where did you get that commons-fileupload-1.0.jar file from? Version 1.0 was released in 2003.
My sense is you should try downloading the latest version of Commons Upload from the Apache site.

[deep raj]

now it compile
but at run in tomcat it shows
java.lang.NoClassDefFoundError: javax/servlet/ServletInputStream
insertimage.doPost(insertimage.java:17)

[David Newton]

What libraries are you deploying? What libraries did you remove from the Tomcat lib directories? If you're getting that message in Tomcat you've done something very wrong. Right now it just seems like you're trying things at random.

[deep raj]

in my app. web-inf/lib folder
servlet-api.jar and commons-filrupload-1.2.1.jar both files are saved
and i saw servlet-api.jar it contains servletinputstream class
yet the error will show?
i don't understand why?

[Prasad Krishnegowda]

check in tomcats lib directory, whether servlet-api.jar is there or not..

[deep raj]

it is there

[Prasad Krishnegowda]

remove servlet-api.jar from your applications web-inf lib folder

[deep raj]

no effect
same error occur

[Prasad Krishnegowda]

Then, I am not able to figure out the cause, can you redeploy your whole application, by removing servlet-api.jar from your applications web-inf lib folder and see.. Also, restart the tomcat server before redeploying it..

[Amol Nayak]

I would suggest you unpack the zip downloaded again from tomcat site and deploy your application in it. While during all this trial and error some jar file must have got deleted.

You're only deploying two libraries with your application?

In any case, you *must* not deploy any JEE API jars with your application. It'd be quicker to just answer the question(s), but okay. At this point it probably *would* be quicker for you to reinstall Tomcat.
