Hi all,

(this was originally a request for help until I solved it, could be useful info for someone else)

Running Netbeans PHP 7.0.1 on Win7 64, with jdk 1.7.0 will break FTP, it seems something in Java 7 doesn't like netbeans implementation of FTP (or the other way around) and downgrading to the latest Java 6 (update 27 at this moment) solves all woes.

Have attached the logs in case these are of use to anyone.

--LOGS--

There are no errors in the FTP log on the server, the last line is always:

Hi Richard,

I can only comfirm the issue,
Yesterday i spent a few hours with several times installing/removing the new JDK 1.7.0 and netbeans 7.01 and I run into the same problems every time.
The FTP option inside netbeans fails to connect, to whatever url is used.
As a result, the update option will not work, but also activating Junit and downloading the plugins catalog fails.
I have Windows7 Ultimate and use netbeans and JDK 1.6 for along time without any issues. I even cleaned the computer from anything related to Java and also modified my firewall by manually allowing Netbeans input/output access, but nothing worked.

So finnally i decided to install JKD1.6.27 & netbeans 7.01 and all problems where solved.

So you are not the only one with this issue.
It seems that the guy's that made the JKD/Netbeans bundle have to do some extra work. Something went wroung.

Regards

Jack.

I can confirm this issue.

Product Version: NetBeans IDE 7.0.1 (Build 201107282000)
Java: 1.7.0; Java HotSpot(TM) 64-Bit Server VM 21.0-b17
System: Windows 7 version 6.1 running on amd64; Cp1252; de_DE (nb).

No time to test the nightly right now though, sorry.

So this is a pretty big deal - I can confirm it too. Basically FTP does not work with JDK 1.7. It sounds like it's only a problem with JDK 1.7 since it does not follow the Netbeans version. Thanks to zeester for pointing out that important distinction. Where do we report problems to the JDK? Is that a NetBeans thing or a Sun thing?

I can confirm this problem as well. Halfway the upload every time on the same moment it tries to change the path or something, it just stops and says the upload failed.

From the Log I see always two errors appearing after eachother. First this one:
"java.net.SocketException: Software caused connection abort: socket write error"
And then this one.
"Caused: org.netbeans.modules.php.project.connections.RemoteException: Cannot log out from server myserveraddresswashere."

The project is a PHP-Project, I use 64 bit Windows 7 Ultimate and I got jdk 1.7.0 and jre7. It must have to do something with a newer version because on my 'old' computer, which has same netbeans but another javaversion probably, this problem does not occur. Even though I made sure that the settings in both Netbeans projects are exactly the same.

If I test the connection with the ftp server it is all good as well. If you need more info from log or something, ask me here.

The FTP Part is:
220 ProFTPD 1.3.3e Server ready.
USER myusernamewashere
331 Password required for myusernamewashere
PASS ******
230 User myusernamewashere logged in
TYPE I
200 Type set to I
CWD /
250 CWD command successful
CWD //inc
250 CWD command successful

Probably gonna need to download FileZilla again..

PS I just tested on my other computer, the only difference there is that after the last line of this ftp thingie, it does a PORT command and then it just continues doing the usual stuff.

Sorry for lack of info in my last post. Most of my evidence is from Wireshark - and a colleague's computer no less. I will transcribe the last few lines of Wireshark obtained when the problem happens.

Frame No. Time Source Dest Protocol Info
188 15.816282 server me FTP Response: 230 Login successful.
189 15.816676 me server FTP Request: SYST
190 15.829459 server me FTP Response: 215 UNIX Type: L8
191 15.831154 me server FTP Request: TYPE I
192 15.843761 server me FTP Response: 200 Switching to Binary mode.
193 15.858793 me server TCP 53006 > ftp [RST, ACK] Seq=60 Ack=128 Len=0

Stepping through the code, the problem happens inside the apache.commons.net.ftpClient call to listFiles(). I do not have the source code in my project so I have not stepped through the listFiles() call yet. At sometime inside that call, the FTP connection is simply reset by my application. Like everyone else, this works on all other machines running older JRE versions (Windows 7 with 1.5 or 1.6, and Mac with 1.5 or 1.6). When I bundle JRE1.5 with my application my colleague can complete an ftp operation successfully, so it is not just a firewall issue.

Well, I don't want to speak for the engineers, but is there some
particular reason you need to use JDK 7? JDK 6 u 26 is nice and stable.
