Comment Topic: JBidwatcher Help / Problems in FC5

George,

for those who need dumbed down instructions ;-) you forgot to tell that

a) JBidWatcher-1.0.jar has to be in the same location as this script is
b) typing JBidWatcher in the terminal only works if
1) you are in the directory /home/bin
or
2) the path to /home/bin was added to the path environment in your shell

I don’t know anything about Fedora FC5 but I suppose a path like /home/bin should include the username somewhere if you want it to install for a single user. Otherwise a location like /usr/local/bin would be more appropriate. Your distribution probably encourages you to use a proper location for either user-based or system-wide usage, which they tell you about somewhere in the documentation.

— Michael

P.S.: You might want to tell your vendor about the confusion these incomplete GNU Java Compiler stuff is spreading among the less geeky users.

Comment Topic: JBidwatcher Help / User agent

JBidWatcher sends the ua. It’s somewhere in the Java code.

Comment Topic: JBidwatcher Help / display item in webbrowser

You’re supposed to enter your eBay username and password which also is saved in the preferences dialog of jBidWatcher.

Comment Topic: JBidwatcher Tips and Tricks / Has development ceased on JBidWatcher?

I don’t know if the vm options are case sensitive because you use -XMx=512m and not -Xmx=512m.

Anyway I think I had some concurrency problems on shutdown with JBW so I turned on the file locking option. May be it won’t help because the file is locked task-based and not thread-based but then it won’t hurt either. I wonder if adding some synchronized code sections could improve concurrent access to the files on disk.

IMHO testing for concurrency or memory problems for these files can be done by just saving the auction manually. If no “Auctions saved” dialogs pops up then you know where to look at. Otherwise you can just kill the process because all data has been saved.

Also some information about the time JBW was already running (hours or days or weeks) and having put the computer into sleep may give some pointers to the right direction. Or issues like a dropped network connection. Sometimes I have to restart JBW to regain updating of auctions.

Comment Topic: JBidwatcher Tips and Tricks / Lockups aka memory problems

You can provide options on startup to the Java vm to use more memory for the heap. Have a look at http://java.sun.com/docs/hotspot/gc1.4.2/. The options are -Xms and -Xmx.

I use “-Xms16m -Xmx256m -XX:+UseFileLocking” on Mac OS X Tiger running JVM 1.4.2 and hadn’t had a single problem with JBW since the change having more than thousands of completed auctions in JBW. Before the tweak I also experienced those lockups.

Comment Topic: JBidwatcher Help / Invisible bidder??

Well, rocket_parts7 seems to like the seller, byuequip. rp7 has 87 times positive feedback, but only 8 of them are counted. If you look at his profile roughly 80 are from buyequip.

If you want to drill down more deeply I recommend “SellersBestFriends” to you, a free java app (http://chromstein.de/sbf/). The app is in bilingual english/german, but because I don’t know if the website is also in english (I think so), I post a direct download link (http://files.chromstein.de/SBF2_2_2.zip).

Because a couple of guys seem to like this seller as much as rp7 does it’s quite interesting to have a look and compare the auctions.

Comment Topic: JBidwatcher Tips and Tricks / Is there a way to post improved source code?

Is there a way to post improved source code? That would be either fixes or improvements to the Java client and the HTML/Webserver part of JBW.

Comment Topic: JBidwatcher Help / Time-fix beta available on request...

I didn’t try your timeslip fix but my clock on Windows XP SP2 didn’t wander off after installing a “real” NTP service which is based on ntp.org sources (http://norloff.org/ntp/). The time service of XP has a 7 day update interval which seems to large for my setup. The ntp.org service measures the drift and updates accordingly.

My timeslip stays at 6-7 seconds after a couple of days without resyncing the server time. Before it would add up to 30 seconds and more.

If somebody has problems settings this up I’ve done some batch install scripts (for W2k/XP) which I could post in this forum. There are also setup packages somewhere for this service.

Comment Topic: JBidwatcher Help / Bids and snipings not working because...

Well, I didn’t change my password lately and have my eBay password saved in Safari on Mac OS X, so I didn’t type my password in at all.

Comment Topic: JBidwatcher Help / Bids and snipings not working because...

The same happened to my until this morning. Using my account I wasn’t able to login into eBay without doing it twice. The first attempt always failed and the second attempt prompted me for the security number. The password was the correct in both attempts (autofill, because login information is saved in Safari on Mac OS X).

Using an account of a friend of mine I never had a problem logging in while testing on this. I tried to login into both ebay.com and ebay.de. No difference at all. It seemed the problems were bound to my account.

I tried to delete all former traces of my account my setup could have. I restarted my router and got a new IP. I deleted all cookies and caches, used another computer with another OS and browser after a clean boot. No way. Then I stopped all ebay activity (JBidWatcher) over the night.

After reading your post this morning, my problems are magically gone. Hmm.

To avoid possible sniper detection attempts JBidWatcher could be changed to include several randomly chosen browser strings and a login interval (if there is such thing), which is randomly changed to +/- 60-120 seconds to avoid login pattern.
