Hi all,

I have recently begun learning java at uni and have encountered, what appears to be, a somewhat unusual problem. Every time I install JDK6 and BlueJ onto my home computer (running win7x64) I suddenly lose the ability to copy files.

At first I thought it was just a virus or some such thing as I could not copy anything for a couple of days, I restored my computer back 2 weeks using my weekly back up, I then re-installed JDK6 and blueJ (They where the only 2 things which I needed to install and had changed in the last 2 weeks) and I now find myself unable to copy and past anything again.

Any help with this would be greatly appreciated, I have tried googling this but have found nothing and I am open to suggestions other than JDK6 being the problem so feel free to let me know any opinions you may have.

Thanks

Brief expert summary tied to the thread: the symptoms described by (Explorer file-copy stops after installing JDK6/BlueJ; TeraCopy later fails when only JDK is installed) are far more consistent with a shell-extension / Explorer integration conflict than a Java runtime bug. TeraCopy is a shell-integrated replacement for Windows’ copy/move handler, so its shell DLL/registration can be disrupted by other installs or registration changes; Explorer problems caused by third‑party shell extensions are a well known class of failures. TeraCopy. (codesector.com)

Concrete troubleshooting (do these in order):

  1. Open TeraCopy and toggle its shell integration / Register Copy Handler (Preferences → Integration) or reinstall the latest TeraCopy so it re-registers its shell DLL, then restart Explorer. This often fixes a broken handler. (blog.codesector.com)
  2. Use NirSoft ShellExView to hide Microsoft extensions and temporarily disable all non‑Microsoft context‑menu/shell extensions; restart Explorer and test. If copying returns, re‑enable extensions in halves to find the culprit. (This is the standard way to isolate shell extension conflicts.) ShellExView. (nirsoft.net)
  3. If still unresolved, perform a clean boot or test in Safe Mode / a new local user account to see whether a startup app/service is responsible; re-enable items systematically to isolate it. Microsoft documents the clean‑boot and Safe Mode diagnostics. (support.microsoft.com)

Notes and follow-ups: on 64‑bit systems TeraCopy’s shell registration can need the correct VC++ redistributables; reinstalling the VC++ x64 packages or TeraCopy itself can help. BlueJ is an educational IDE that typically needs a JDK but does not normally install Explorer shell handlers; that makes a third‑party shell extension (TeraCopy or another tool) the more likely cause than BlueJ/JDK alone. If none of the above isolates the issue, capture Explorer errors in Event Viewer and consider a full TeraCopy uninstall/reinstall as a last step. (blog.codesector.com)

Hey..

I am sure that its NOT problem of JDK .. but its problem of your bluej.

There are many good IDE's like eclipse ..

so Try another IDE other than blueJ..

ok, I restored my computer back to before I installed both and just installed the JDK, the result of this being that I can now copy, BUT for some reason teracopy wont work, I can live with this but it is interesting that as soon as I installed JDK teracopy stopped working.

Also, the reason I am using BlueJ is that that is what is used in my textbook and lectures, so it seems appropriate to use the same environment, although I will look at some other environments, just to see which are better for me
