FTP Upload (unknown reason) problem

[towntalk]

Hello all,

I've scanned through quite a number of search engine results on this topic and never found the exact problem and wondered if anyone here has encountered it.

I am running Netbeans 7.0.1 PHP IDE on windows 7 with the latest JAVA SE Development Kit (64 bit)

I have a project with a FTP connection that gives me the following error when i try to upload something.

###########################################


230 User ***** logged in
TYPE I
200 Type set to I
CWD /path/to/upload
250 CWD command successful
CWD /path/to/upload
250 CWD command successful
PASV

Summary
====================
Failed:
file ****.php Cannot upload file ****.php (unknown reason).
Runtime: 170 ms, transfered: 0 file(s), 0 KB

#######################################

It shows hear that authentication actually happens so it's not username password problem.

I have tried FTP with and without PASSIVE mode still the same problem.

I have tried re-installing both netbeans and java still no luck.

I am completely bamboozled

Any ideas?

I found out that it was a windows firewall issue.

I now need to find out how i can enable windows firewall and use netbeans at the same time..

any ideas?

No, but I would suggest following this up with Windows Firewall support,
since it is likely that the solution involves configuring your firewall.

This is a problem with the latest update for Java. You need to uninstall Java
7.0 and Java SE Development Kit 7.0 (You should keep Java 6 with the latest
updates (update 24 or 27)). If you just keep the old versions, everything works
great.

Well actually you don't need to uninstall JDK 7. If you have a JDK 6 installation (again, use update 24 or later), select that JDK when you install NetBeans. If you have already installed NetBeans, consider uninstalling it and reinstalling it. If don't want to do that, you still have a couple options:

• If you usually want to run NB using JDK 7 but only occasionally want to run it with JDK 6, launch NetBeans from the command line with the option --jdkhome {directory of JDK 6} when you want to run NB with JDK 6.
  
• If you just want to run NB with JDK 6, open NETBEANS_INSTALLATION/etc/netbeans.conf and change the value of the property netbeans_jdkhome to the location of your JDK 6 installation. This changes the default JDK to JDK 6.

If you are developing JDK 7 Java apps, please note that you do not need to run NB in JDK 7 to do so! You can set up NetBeans to run on JDK 6 and in Tools > Java Platforms, add a JDK 7 platform. When you want to develop a JDK 7 app, select the JDK 7 platform when you create the project.

I can confirm that this solution works. I'm using Netbeans 7.0.1 on Windows 7 64-bit. Had 32-bit JRE 7 installed. Same upload problems as everyone else (upload failed, cause unknown). Downloaded and installed 32-bit JRE 6 beside JRE 7. Edited <netbeans dir>\etc\netbeans.conf so that:
netbeans_jdkhome="C:\Program Files (x86)\Java\jre6"

Now uploads fine.

There is solution of the problem (works for me):

It strikes me that disabling a feature of your firewall to deal with connectivity issues for one application is perhaps overkill.

There's some authoritative learning on this topic at
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7077696

The takeaway:

a) The underlying problem is that Java 7 (unlike Java 6) uses IPv6 and the Windows Firewall does not play nicely with IPv6 (or at least not in the form used by Java 7 -- determining whether this is REALLY a Microsoft bug, as Oracle says, as opposed to Java 7 having a buggy implementation of IPv6, is certainly beyond my abilities).

b) You may be able to solve the problem by running the JRE with -Djava.net.preferIPv4Stack=true, but I have not yet tested.
