The import org.apache cannot be resolved and I am not sure why?

Alright, so I decided to build myself the simplest of simplest ftp client so that I could understand how this works:
Ok, I have parts built but I am trying to include the following things:
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPFile;The error I am getting from eclipse (which is the editor that I am using) is:
The import org.apache cannot be resolvedThe same thing happens when I try to do:
import com.jscape.inet.ftp.*;I have an idea what is going on with this but I am not entirely sure. I think I need a package that I must download from apache or somewhere that might give me access to libraries?
I would be grateful to any help...
Thanks,
Adam Scott

Yes you need to have the classes that you want to import. If you have them then you need to add them to your project's classpath.

The import org.apache cannot be resolved

Hi All,
I am a Java\Eclipse newbie. I am trying to import the org.apache.xerces package, and the import is failing with this error:The import org.apache cannot be resolved
I am not using Maven\Ant for building the project. I know I need to download some class files\jar files to get this to work, but I am not sure where to download these packages from. Could someone please help me out here?
import org.w3c.dom.Node;
import org.apache.xerces.parsers.DOMParser;
import org.apache.xerces.dom.traversal.TreeWalkerImpl;
import org.apache.xerces.domx.traversal.NodeFilter;
import org.apache.xerces.dom.DocumentImpl;
THanks a lot!

Well, if you are in fact looking to download the JARs for the Apache Xerces project, you should be able to find them at the Apache Xerces project page.
If you already have the JARs downloaded, you need to make sure that they appear on your CLASSPATH, otherwise your application will never find them. Since you are using an IDE, this should be as easy as adding the JARs to your project.

The import com.crystaldecisions cannot be resolved

Hi,
I installed Eclipse Java EE IDE for Web Developers (Version: Helios Service Release 1) and the Crystal Reports SDK via Eclipse "Install New Software" feature described at http://www.sdn.sap.com/irj/sdn/crystalreports-java
I have a sample code now and get in one of the JSP-files in Eclipse the error message:
Multiple annotations found at this line:
     - The import com.crystaldecisions cannot be
      resolved
     - The import com.crystaldecisions cannot be
      resolved
I got the Crystal Reports for Eclipse Developer Guide and configured my project in Eclipse: menu Project -> Properties and added the CR library to the Java Build Path and activated CR at "Project Facets". I still get the error message... what's missing?
Thanks!

Hi Stefan,
Instead of adding the "Add external class folder" try out to add to your Java Build Libraries "Add External JARs"
When you click on this button you can select the path of all the jar files from your Business Objects installation directory.
E.g. C:\Program Files\Business Objects\common\4.0\java\lib"
and "C:\Program Files\Business Objects\common\4.0\java\lib\external"

Anu

My iphone5 crashed Wed May 29 and I am not sure why.. I had to do a restore and have been trying to slowly get everything back on the phone... Yesterday June 6 it blacked out once and I don't have everything on the phone as before.... New one?

My iphone5 crashed Wed May 29 and I am not sure why.. I had to do a restore and have been trying to slowly get everything back on the phone... Yesterday June 6 it blacked out once and I don't have everything on the phone as before.... Is it damaged and should I try to get a new one?

Thank you again for all of your help!! I really appreciate it!
I think I am following -- I was able to upload to my iPhoto and all photos and videos are there that is a plus! I tried to create an Event in my iPhoto and put all of my photos in that event but for some reason, now my iTunes it not recognizing that Event in my iPhoto. It is not allowing me to import just that event at the moment but I may be doing something wrong. At least all of my pics and vids are in iPhoto so that is a plus and I know they are at least saved somewhere. Just for some reason, my iTunes it not locating the event that I created with only those photos.
Thank you for letting me know about my contacts! How do I know if I have the contacts app?
Also, I had no clue that my iCloud could be backed up via cellular data! However, is this a new feature with the most updated iOS?? Unforutnatly I am like 2 iOS updates behind because I don't have enough storage on my phone. I still get the notification that my phone needs to be plugged in and connected to wifi in order to back up to the cloud :-(
How can I sync using USB? Right now when i click on the info tab for my iPhone in my iTunes this is the answer that I get -- I am a little unclear as to what it means.
Sync Contacts:
Your contacts are being synced with you iPhone over the air from iCloud. Over-the-air sync settings can be changed on you iPhone

I have a retina MacBook Pro, and a thunderbolt display. I've noticed that randomly when docking to the display (I close my laptop screen) my Launchpad layout will randomly reset. It isn't consistent, and i'm not sure why this is happening!

This is very annoying because I really enjoy using launchpad. I have a lot of applications in there and I hate having to reorganize everything. I messed with a third party application before to backup/restore my launchpad layout, but it had some issues with Mountain Lion so I ditched it. Any thoughts?

Threads are just processes that link together like the threads in these discussions, well, maybe that is a bad example given how disjointed these get
It looks like you are not pushing the cpu or hard drive enough to cause your behavior. Not sure what the temperature limit on that cpu is, on the newer models it is around 100-110 °C which is notciabley hot, and the system shutsdown for self protection at the thermal limit.
You could be hitting a thermal limit causing that behavior...so do you see good behavior at lower load levela on the system? Does this only happen with when you are under the high graphic loads?
Trying to zero in on when this occurs to see if we an isolate the problem.

The import javax.ejb cannot be resolved

Hi all,
I have a bean working fine when deployed as jar on weblogic but it gives the above error when deployed as ear. Deployment goes ok but when I try to use it I get the error.
Anybody has any idea of what the problem could be?
Thanks,
A.

I figured out that if I include j2ee.jar in the ear file and the entry j2ee.jar in the Class-Path of the manifest file inside the jar then everything works, but I can't understand why...do I ALWAYS need to include j2ee.jar for every aplication that I deploy?

I get "General Error" when trying to playback unrendered video, and when trying to export to my desktop and I'm not sure why.

I import video footage into Final Cut Pro 7, added some effects like motion blur and colour correction, and cannot playback the video whilst it is not rendered. I click the play button but it just says "general error". This also happens when trying to export to my desktop "general error" once again. Does anyone know what is going on?
My RT settings are:
Safe RT or Unlimited RT (I get the error on either setting)
Framerate & video quality - Dynamic
27" iMac i7 @ 3.4GHz
4GB Ram
2GB Radeon 6970m

Hmmmm it seems to be just that file. The rest of my files are fine. I tweaked some settings and tried other files and it worked, so maybe it was just me, I am very new to Final Cut after all. Turns out I'm OK now! Thanks anyway!

I just noticed that i have a shared library from a stranger. This is very concerning and I am not sure why or how this happened. Please help!

What do you mean by a shared library, what is it you are looking at.

Late 2011 Macbook Pro battery is toast, and I am not sure why!

I have had my late 2011 Macbook Pro for 3 years and 5 months. Before I left for vacation on July 28th my battery held 98 percent charge. I turned it off and put it in my closet. Now when I have came back my battery holds 2.2 percent, not even enough to be unplugged for a second (128mah). I of course expect my battery to go at some point but my battery has only been through 340 cycles and apples site says the max is 1000. Any suggestions into why my battery is dead after so few cycles? Additionally any suggestions into where I can buy a battery for my computer?

ipodperson1,
your battery holding 98% charge before you left for vacation doesn’t tell the most relevant information — what its Full Charge Capacity was then. Is 128 mA·h its current Full Charge Capacity, or its current Charge Remaining? That is, is the battery merely drained, awaiting a full recharge, or is it now unrechargeable?
You can buy a replacement battery for your MacBook Pro by taking it to an Apple store, or if you prefer to replace the battery yourself, you can buy a suitable battery from reputable third-parties, e.g. NewerTech batteries from OWC.
