Using VxWorks A653 v2.5.0.2 I am getting an exception being generated in tRootTask during startup:
data storage
Exception current instruction address: 0x50000120
Machine Status Register: 0x0000fb30
Data Exception Address Register: 0x00000008
Integer Exception Register XER: 0x00000000
Condition Register: 0x40000088
Exception Syndrome Register: 0x01000000
Partition Domain ID: 0x007539a0
Task: 0x521f5920 "tRootTask"
the tRootTask does spawn a number of other kernel tasks and also creates a task for the user partition. But the entry point to the user task in the user partition never seems to run (printf() statement is not hit). After the exception occurs it is possible to attach a debugger, but the tRootTask itself is deleted by the exception. If I access the shell after the exception, attempting to display the contents at 0x50000000 contains fails, as if it is unmapped memory. This may be the root cause of the exception, but why it's inaccessible is unclear.
So I am searching for a way to debug why the exception is happening. I'm new to this OS.itself
Look in your linker map for the
"Exception current instruction address: 0x50000120"
Or if the shell has "lkup"
-> lkup 0x50000120
should give the nearest global function that's throwing exception.
Data Exception Address Register: 0x00000008
looks like zero page access, but you need decipher the "Exception Syndrome Register" in PowerPC manual to see if it's the right condition code?
"tRootTask" is the first thread in the context, so it's some sort of startup code that's failing. But it's so early, you probably need a JTAG debugger to get a breakpoint on it.
I have my web application built using struts 2.3.1.2. I have following pages/actions where I don't get any OGNL exception as a warning/notification.
JSP page - containing 3 text fields name, address, phone
struts.xml file - devMode = true and corresponding action entry using default interceptor stack
action class where I have properties only for two request parameters i.e. for name and address
Above is running fine and I don't get any warning/notification exception.
Now, recently I have upgraded to struts 2.3.14.2 And I have started to get below warning/notification exception on log file:
Developer Notification (set struts.devMode to false to disable this message):
Unexpected Exception caught setting 'start' on 'class com.xyz.DetailsActionSupport:

By google search, found two answers:
to add the exclude parameters in struts.xml for Param interceptor
disable the development mode defined in struts.xml
I can do that, but, don't understand what has changed in struts version so it has started to print the exceptions as notifications/warnings?
Below link will tells us how it shows warning exception:
http://struts.apache.org/release/2.3.x/docs/parameters-interceptor.html
Refer the section Warning on missing parameters from above link
It seems that the portTypeName parameter of the axistools-maven-plugin (version 1.3) cannot be set.
The classOfPortType parameter is a required parameter and cannot be omitted but when setting it alongside portTypeName the following error appear:
Embedded error: Java2WSDL execution failed
invalid parameters, can not use portTypeName and classOfPortType together
I see there is Jira issue here. Is there a workaround?

I'm trying to write a windows service. It installs fine, but fails when I run it with the following exception. I've searched for the string "MyNewProgramService", but I can't find any conversions that would throw this error. I've also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring. I'm thinking it's somewhere in the auto-generated configuartion/setup code. Any ideas?
Event Type: Error
Event Source: MyNewProgram Event
Category: None Event
ID: 0
Date: 4/15/2010
Time: 12:48:34 PM
User: N/A
Computer: 20F7KF1
Description: Service cannot be started. System.InvalidCastException:
Conversion from string "MyNewProgramService" to type 'Integer' is not valid. --->
System.FormatException: Input string was not in a correct format.
at Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value,
NumberFormatInfo NumberFormat)
at Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value)
--- End of inner exception stack trace ---
at Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value)
at TaskManagerFailureHandlerService.MyNewProgramService.OnStart(String[] args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)
it falls in method MyNewProgramService.OnStart, there Conversions.ToInteger is called somewhere. Just search for it in method. Then check parameter. It might come from config or something, thats why you don't see string in text.
Check your configuration file.
You might also check the account the service is running as. Just as a test go to the login tab in the services list and have it login under your own account. If the problem vanishes it's a permissions problem.
The WCF service is deployed on different machine.
Im able to get the http://MyServer/MYService.svc/jsdebug file by giving
<identity>
<dns value="ServerName and the portnumber"/>
And I'm able to invoke the service method using javascript.
After invoking the MyMethod.
I get this error in the javascript --> The server method 'MyMethod' failed, status 404 (in failedCallback)
MyMethod returns a Boolean value in svc.cs file after performing a datacheck.
These are the errors came up when I used Firefox Firebug:
When I call the same service using VS2008 in my development environment it works fine.
I found that following are the files which are not loading while using Ajax enabled VS2005
1) MicrosoftAjax.debug.js(3.5)
2) MicrosoftAjaxWebForms.debug.js(3.5) During runtime
Its obvious that 3.5 debug files doesn't load but, 1.0.6 debug files should load without the errors displayed below.

Appreciate your inputs.
Seeing as you have Firebug installed, you can use it to check the HTTP request and response to see if they contain more information about what went wrong.
