First of all: Happy New Year. Here's hoping 2012 is a good one!
I have a problem with a mysterious vanishing GUI!
I start WebHarvest to edit some scripts but the GUI no longer appears. I'm
running Win XP SP3.
javaw.exe is launched (one instance for each time I try to start webharvest)
but no GUI. I thought webharvest_all_2.jar might have got corrupted somehow so
I downloaded it again but this didn't solve the problem.
Any ideas?
Many thanks
Andy
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
This problem with the IDE has now happened on a second PC !!
After WebHarvest on my laptop became unusable due to the IDE not launching, I
loaded WebHarvest onto a 2nd PC. This worked fine for a few days but is now
doing the same thing!
I double-click webharvest_all_2.jar as usual. I can then see javaw.exe running
as a process in the windows task manager. Nothing shows in the Application
pane of the task manager however. When I shut the PC down, it pops up a window
saying WebHarvest is running and needs to be closed but the GUI is never
visible.
WH still runs perfectly in command line mode.
I've completely removed both WH and java from my PC and reloaded them. Made no
difference.
I'd really appreciate some help here as I cannot use WH at all now as I can't
edit scripts in the IDE.
Many thanks
Andy

Here's an interesting observation: WebHarvest still runs perfectly in command
line mode.
It's just the GUI that doesn't work!
I'd really appreciate some help with this as WebHarvest is unusable as it is
now.
What additional info can I give that would be useful for diagnosis?
Many thanks

I found that I still had a copy of webharvest_all_1.jar. The GUI/IDE on this
version still works!
Of course it doesn't recognise the version 2 processors such as "database" so
it's of limited help.
Hi All
Today I have the same problem.. on WinXP, but it was ok yesterday
when I try to run the program by double clicking it also doesn't apear
then I try to run GUI in cmd:
java -jar webharvest_all_2.jar
and it return folowing exception:
at org.webharvest.gui.Settings.readString(Unknown Source)
at org.webharvest.gui.Settings.readObject(Unknown Source)

So, it caused by lacking a memory
Then I try to increase memory by setting -Xms1024m
java -Xms1024m -jar webharvest_all_2.jar
and it returns the other exceprion:

Unfortunatly, I have only 2Gb of RAM on my computer and I'm not able to set
more heap size by -Xms.. and I steel can't run the WH GUI
I've solve the problem when I looking through this forum
The solution is:
to remove webharvest.config file in your local temp
Excellent! That worked.
Thanks very much.
