Velocity, Struts and Tomcat Clusters

2005-05-06T13:16:00.000-07:00

I just recently found my self using Tomcat with Velocity and Struts
And as would be expected I needed to use more than one Tomcat server for load balancing and Reliability so I looked into how to Cluster Tomcat.

There are 3 options with tomcat 5.0

Save your session to a file
Save your session to a database
Use Tomcats multicast Replication

I played with #2 and #3 and found out that Velocity puts a Object into the session object that is used to synchronize on.

It creates a empty Object and put it into the Session then when doing any actions it uses the Object as a mutex so that only thread can act on any session. This sounds smart? Right?

Well when I tried to serialize the session I ran into many problems because Object is not serializeable.

I was banging my head against the table over and over trying to figure out why I was getting session.mutex is not serializeable.

Then I had to try and find where session.mutexwas getting put into the session because I knew that I was not doing it

Finally I found out that it was Velocity Tools that was putting an object into the session.

So I the solution was to recompile velocity tools so I could extend it and I do a synchronize on the session itself. Now there are no extra object to passed to the other clusters.

Mac New Java is a Bust- Technorati Saved My Butt

2005-04-19T14:24:00.000-07:00

So I installed the new update on my power book and BAM. My java stopped working. Right in the middle of a big java project.
I could not believe it.

I jot the update this morning but waited until after lunch to reboot my computer and then every time I ran "java" I get a "segmentation Fault".
I was freeking out so I tried to go to versiontracker with no luck. Then I went to sun's web site. Looking for a binary that I could use but found Nothing.

Then a friend told me to check Technorati so I did. I searched for "mac java" and the first link had the answer.
I had to install 2 patches again and I was back on track.

Here is the site with the step by step on how to fix your mac.

Day 5

2005-02-25T22:41:00.000-08:00

So My Treo has been happy for days now. The Phone does not reboot and I have not had any problems with it. I am happy again.
I am Still going to try to find out witch piece of software was causing the reboots on my device. The only 2 pieces of software that I have not reloaded onto the Treo is the Bolwing game and the voice software that came with it.

I have downloaded Buttler I have not tried it yet but it sounds like it has some very nice features.

Treo 650 Day 3

2005-02-23T08:40:00.000-08:00

So My Treo is very happy. So not installing Warfare Inc. or the Voice Dialing program seams to have fix it. Or maybe its the fact that I am not really running anything other then the Phone app right now. But its been 1 full day with no problems.

So tonight I am going to add Warfare Inc back on to my device and see if it will still work. I hope so Warfare Inc is one of the coolest games I have played on the Palm.

So I went home and I installed Warfare Inc on my Treo 650 and I have had no problems. I played the game for a while I was able to get to the 3rd level and my phone is still working. It has not rebooted and it has not had any other problems.
I am thinking the problem might be the Voice software that came with the device.
My Plan is to give my current configuration a day or two to make sure it is working correctly then add a new piece of software.

Treo 650 Day 2

2005-02-22T08:42:00.000-08:00

So I reloaded everything except for Warfare Inc and my Treo is working fine So Far.

Now I am just waiting to see if it will stay that way.
The strange thing is that I looked on the Treo software compatibility list
http://www.palmfocus.com/treo650software.asp and it is listed as working ok.

But last night I was playing Warfare and after I was done playing I tried to dial a number on my Treo and it would just reset the device. So I unloaded everything and reloaded everything except for Warfare and today I can use the phone.

Its very hard because I played the game for a while yesterday and the phone was fine it was only after I had played the gave for an extended period of time. I wonder if the bug is time based or if it has anything to do with the software I installed on it

Treo 650 Day 1

2005-02-21T20:44:00.000-08:00

So I just got my Treo 650 and boy am I happy or at least I thought I was.

I got it yesterday and the first thing I did was load it up with Documents To Go the Games that come with the Treo 650 and some other Palm Games like Warfare.

Then I got to work today and the Voicemail button did not know what number to dial.
I called the Cingular help support and they said this is a know issue here is the fix
http://forums.palmone.com/pe/action/forums/displaypost?postID=20159264

It says that just don't use the voice mail button and create your own. Sounds great to me.

Then my Treo Started to reboot every time it received a call. This is not what I want my phone todo to reboot everything it get a call. Also when I tried to make a call if I hit the dial on the touch screen the device would restart. I can use the button to make a call but not the touch screen

So I called the Treo Help line and they had me reboot it by pulling the battery 5 times and see if it fixed it. It did not. Then they asked me to do a hard reset witch would delete all data on the device.

So I did it and the device worked. It could receive calls and make them but my phone book was deleted when I did the reset.

So I went home and tried to figure out which program was causing the problem so I one by one reinstalled my program's. I installed Documents To Go new version that I downloaded. Then restarted the device and it worked. I did this with all of my programs. And it all worked then I was playing Warfare a very cool Starcraft like gave for the Palm and when I was finished I tried to make a phone call and me device restarted.

So I had to reload the device AGAIN. I put a few games and Documents On The Go back on the device and now it seams to be working.
I will wait to see what tomorrow brings
