GTD: Treo now Syncing OTA with GCal

I had all but given up with the idea of getting my Treo to sync with Google Calendar over the air (OTA) using the Java GCalSync midlet because it just appeared that the IBM Java Environment used on the Treo didn't support it. Then I came across the missing piece of the puzzle. Apparently the PIM access libraries for Java are in a separate directory when you download the Java environment and have to be installed explicitly. After I did this I was able to get GCalSync (a free program) to synchronize my Google Calendar with my Treo without needing any computer in the loop at all. This is a happy thing :-).

The steps, if you want to do this yourself, are:

  1. Download the Websphere Everyplace Java VM from http://www.palm.com/us/support/jvm/download.html and unpack it.
  2. Install the J9JavaVMMidp20.prc and JavaVMCheck_enUS.prc files from the JVM/ARM4T folder onto the Treo
  3. Install the fileconnect.prc, pimop.prc and PIMPrefs.prc files from the JSR75 folder (you can also install localized prcs if needed, but english speakers will not need to)
  4. Install both files from the JSR172 folder
  5. Sync your Treo with the computer, so that the prcs are copied on to it
  6. Reset your Treo, really, seriously, it doesn't make you but I found things work a lot better if you do
  7. Find and start the IBM Java VM from the Treo launcher
  8. Hit the install button
  9. Type in: http://www.gcalsync.com/gcalsync.jar for the URL and hit OK
  10. The gcalsync program will be downloaded and installed
  11. Run it and follow the instructions (see the gcalsync site for help here)
That's it, no great mystery, I just can't believe I missed those extra install folders for so long. I also had to turn off the preference where gcalsync tries to use the google settings for timezone, otherwise the appointments came through at the wrong time, but otherwise everything works fine now.

I hope the same is true for you.

Hey Dick, I also had given up on ota treo gcal synching and was using the html calendar workaround that you referenced in an earlier post. This seems to be working well.
Also, I can't imagine that you don't know about it, but you would probably really like gtdgmail.com. It takes some getting used to, but I like it and it seems to fit w/how you described you are already working. Thx again. Jeff

Dick,

I'm also excited to finally find a way to make this happen.

I've gotten to step 6 and don't know how to access the treo launcher.

# Find and start the IBM Java VM from the Treo launcher
# Hit the install button

I know that it was installed with the hotsync so can someone let me know how to proceed to the next step. Where do I find this to hit install?

Thanks,
Gerald

Thanks - just got this to work

coupl of issues to resolve - all day events in gcal come across literally as all day as opposed to "no time" in the treo calender. Also repeating events on the TREO do not come across as repeating on gcal - only the original event is listed.

More research

Dear Mr Wall:

Do you mind if I use your image of a treo with google cal (http://static.flickr.com/

on my blog about treos and gcalsync? (http://gcalsync-treo.blogspot.com/)

Thanks,

I ran into a problem. I followed your instructions to the T but when I go into my Treo 650 and either do a Sync or a Full ReSync it reboots when it trys to "read phone events." Do you have any idea how to fix this? Thanks!

Wow, what a mess.

I'm glad you had the instructions on loading those extra files from the JVM folders, I never would have thought of that.

The Gcal tool has a bit of a problem still with time zone handling, and getting it to turn OFF the internal handling doesn't work right, either. I had to set download compensation to -4hr and upload compensation to +4hr to get events to sync at the right times in both directions.

And a repeating event at 9pm didn't sync at all, even as individual events. I'm not sure why. But I'm happy it works, even to this degree.

I would have used GooSync.com if it didn't work. I didn't like the idea of having Yet Another Service in the loop, so I'm glad the tool worked directly.
