Tomcat Unloaded Application Automatically

Hi,
I have problem with Tomcat 5.
I have configure 2 ports in my tomcat. There are 3 applications sitting in the tomcat.
Tomcat unloaded one of the application in the Tomcat automatically. The last request that was being processed by the application which was unloaded by the Tomcat was a successful processed request with HTTP Response Code 200 returned back to the client.
Does anyone knows how to solve / investigate the above problems?
Please advice,
Any suggestions will be appreciated.
Thank you,

Try opening a cmd window and navigating to the TOMCAT_HOME\bin directory. Start tomcat uing the command:
tomcat5.exe
This should run tomcat in th ecurrent window and if tomcat fails the window should remain open. You may want to increase the window buffer size to capture all error messages.

Why do some applications automatically open at startup

I just installed mountain lion. I noticed that when the computer starts up microsoft windows and excel open automatically. I have another application that does it sometimes as well. why do some applications automatically open at startup? How can I change this?

Quit them before shutting down the computer, and check the list of login items in the Users & Groups pane of System Preferences.

You have 14 days to return the computer w/no questions asked. Plus you have 90 days of FREE phone tech support on top of your standard 1 year warranty unless you also purchased AppleCare which gives you an additional 2 years of coverage plus FREE phone support.
Strongly suggest that you take FULL advantage of the above before it runs out. Let Apple deal w/the problems.

Can't stop applications automatically starting in user account

I created accounts for each kid.
Parental control is active, but no restrictions on which applications they can use; just website restrictions and time limits.
Allowed them to modify the dock.
Each time they log in various applications automatically start and removing them from the startup list does not seem to solve the problem, and one is not even on the list.
The "re-open windows" check box is NOT selected when they log out and I watched them quit the applications before logging out.
Example: for one account iTunes Helper always shows up on the startup list... I try to remove it in their account and it just pops back up... this appears to cause iTunes to autostart each time the log in... annoying.
Example: same account, the System Preferences always start up... fortunately it is locked so the kid can modify anything. But again, annoying.
I propagated read/write permissions through their account folders (thinking maybe some settings are not being recorded)... but no luck...
I may just try to re-create their accounts but was hoping to find the answer to this most perplexing issue.
Thanks,
mk

Aha! Even though they had permission to read/write their files, apparently the ownership was not theirs on all of the files, this must have restricted the mods to their account.
Thanks for the "jog".
Background:
This permission state stemmed from a full re-build/re-store I did about a year ago when the hard drive crashed (with encrypted files in the my account, no less)... The backups were out of date (long story) and it took about a week to recover and re-assemble the sparsebundle bands from the broken drive (I only lost 12 pictures!... Disk Warrior really helped with that one!)... anyway I managed to install a new drive and re-stored all of the accounts, but apparently some of the library states had me as the owner... If I think long enough I probably remember how that happened.
Again, thanks for "remembering" for me ;-)

Is jakarta-tomcat is Application Server ?

Is jakarta-tomcat is Application Server or Only Web container ?

I think we can call it application server, but there's something we have to make clear.
Technically, Tomcat isn't a complete application server, it's only a JSP/Servlet container. But web server is so simple that it doesn't take much effort for a server like Tomcat to embed web server function, so Tomcat can serve as ordinary web server as well. That I say he isn't a complete app server is because it doesn't support EJB and other application model.

[Unload SWF] - Automatically unloading a swf while loading - GC issue?

Hi, I am trying to load a few style SWFs at runtime using the StyleManager.loadStyleDeclarations. There are more than 4 style SWFs and I load them through a for loop and add the IEventDispatcher to an array as a reference.. The files seem to load properly. But some times, some of the style SWFs are automatically unloaded . I see the [unload SWF] in the log... I am not sure how to avoid the files being GCed at the time of loading... Also it seems like they are being loaded/ decompressed twice. Please see the log below...
[SWF] /Flex/com/../styles/Common.swf - 45,421 bytes after decompression
[SWF] /Flex/com/../styles/StyleSkin.swf - 253,886 bytes after decompression
[SWF] /Flex/com/../styles/StyleSkin_Fonts.swf - 440,292 bytes after decompression
[SWF] /Flex/com/../styles/ StyleSkin _Assets.swf - 189,281 bytes after decompression
[SWF] /Flex/com/../styles/ StyleSkin _Assets.swf - 1,153,335 bytes after decompression
[SWF] /Flex/com/../styles/ Common.swf - 1,153,335 bytes after decompression
[SWF] /Flex/com/../styles/ StyleSkin _Fonts.swf - 1,153,335 bytes after decompression
[SWF] /Flex/com/../styles/ StyleSkin.swf - 1,153,335 bytes after decompression
[Unload SWF] /Flex/com/marketlinx/mls/client/ui/styles/StyleSkin_Assets.swf
[Unload SWF] /Flex/com/marketlinx/mls/client/ui/styles/Common.swf
[Unload SWF] /Flex/com/marketlinx/mls/client/ui/styles/StyleSkin _Fonts.swf
How can avoid the files being GCed. is it because I re use a single Loader (loadStyleDeclaration) to load multiple files?

Both the copies go away.. and I don't load them twice , only once through a loop and when i debug and see the for loop below is executed only once... Am I not doing it the right way? . I am failry new to Flex and I couldn't find why Flex loads it twice
This is how try to load them in the application...
for (var index:uint = 0; index < styleSheetFiles.length; index++){
styleSheetsLoaded[index] =
false;
// Load the stylesheet files
var styleSheetFileFullPath:String = STYLESHEET_FILE_BASE_PATH + (styleSheetFiles[index] as String);eventDispatchers[index] = StyleManager.loadStyleDeclarations(styleSheetFileFullPath)
as IEventDispatcher;
trace("loading: index" + index + " file:" + styleSheetFileFullPath);
// It doesn't matter whether the result is complete or error
(eventDispatchers[index]
as IEventDispatcher).addEventListener(StyleEvent.COMPLETE, styleSheetFileLoaded);(eventDispatchers[index]
as IEventDispatcher).addEventListener(StyleEvent.ERROR, styleSheetFileFailed);}
In the complete event I try to trace that the particular file has been loaded to see whether it has been loaded... But i don''t see it there...

Tomcat getting restart automatic

Guys,
We have a desktop application distributed using java web start.
We are using tomcat 5.0.28 as web server.
There are many other applications which are distributed using this server.
Now the problem is when ever any application jar file is changed and put in the tomcat folder the tomcat server is shutting down automatically.
Is this controlled by any parameter in the tomcat configuration
please let me know your thoughts
Thanks,
Balaji

Sorry guys found the problem.
The jar file deployed on tomcat was referred for starting rmi server.
When the jar file is changed we were stopping and restarting the rmi server.
In the stop script of the rmi server we were killing all the java process running with a particular user id.
Since the tomcat web server process and the rmi server process were from the same user id it was causing the problem
Thanks,
Balaji

How can I port an existing Tomcat (JSP) application in SAP Netweaver 2004s

Hi All,
I want to port an existing JSP application (using Tomcat as Web server) in SAP Web AS 6.40.
Please any one suggest me.
Eagerly looking forward to your reply......
Thanks and Regards
Avijit Dhar

Hi,
The maximum number of work processes depends on several things like the below.
1) Majorly on Your primary Memory
2) Hardware capacity
3) Operating systems
4) SAP version as well...
You need to calculate the work processes with your primary memory.
Every work process should take 150 mb space on memory.. so you need to increase the work processes that should be campatible with your primary memory.
And please read the OSS notes as suggested by our frnds then go ahead with your rquirement.

When I run a application in fullscreen mode while using the Firefox browser, the application automatically minimizes, e gets back to normal only if I close the Firefox. How can I solve this problem?

Hello, I'm writing it to inform you that I am having some problems with mozilla firefox 3.6.10, and I know that other people are having the same problem: Ever I run any fullscreen application, like games, while using mozilla firefox 3.6.10, it automatically minimizes (the program, not the browser). I'd like to find a solution. Sorry about the bad english, I'm a brazilian. My operational system is Windows 7 x86, and I have a Pentium E5300 processor, motherboard MSI (MS-7267), and 2GB of RAM DDR2. It's a Desktop Computer. Thanks for all.

Webdynpro application automatic start after j2ee startup

Hi ,
Is there a way to automatically start any specific webdynpro applications after j2ee startup
Oren

I guess you can write batch file for that.
Example
suppose you have a bat file which starts J2EE engine, startJ2EE.
You can write a new bat file with following commands.
startJ2EE.bat
explorer http://<server>:<port>/webdynpro/<URL as application>
Let me know if you need more help

How to Unload application in mxl

HOW i can Unload two application same time using mxl
This is my client requirement
First I need to check any active sessions is there (users are logged if so we cannot unload the application & get member info into spool file)
1)HOW TO SET THE FLAG CONDITION IN MAXL EG FLAG=1 IAM GOING FOR A UNLOADING OF APPLICATION ELSE IAM NOT GOING FOR A UNLOADING THE APPLICATION,Serially Unload the other applications
Can any body do the sample coding
Regards
Shenna

Can any body do the sample coding^^^I hope you're not really expecting that. However, I am available by the hour. :)
First I need to check any active sessions is there (users are logged if so we cannot unload the application & get member info into spool file)Are you saying you want to check if there are active databases?
You can use the MaxL command display application all ;
See: http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_techref/maxl_dispapp.htm
You can tell if users are logged in from the users_connected property.
I think you're going to need to pipe this to a text file and then use Perl/VBScript/whatever your scripting language of choice is to read this and then go from there. MaxL does not have the complex interrogation and branching logic you are likely to need.
Check out my blog post on making Planning-derived filters METAREAD instead of READ. You don't care about that -- take a look at the source code that pipes output to text and reads it. I wrote it in VBScript because I am a Fred. You should be able to use that as the nucleus of an approach.
Have fun -- you've got a cool little project there.

Cameron Lackpour
P.S. I didn't write code, but I gave away a halfway decent approach. Sometimes there is such a thing as free beer. :)
