globalIDForObject without a lock

2014-11-21 Thread Raghavender Bokka 
Hi Team,

We are getting deadlocks in our production environment. The following is the 
warning message generated in the log files when we enabled the ERX logging. We 
are using Project Wonder ERXEC.newEditingContext() throughout the application 
and we do not have any explicit lock or unlock code in the application:

--
9201362 [WorkerThread93] WARN er.extensions.ERXEC.LockLogger  - called method 
globalIDForObject without a lock, ec=er.extensions.eof.ERXEC@1296d1d
--

Any help would be appreciated.

Thanks,
Raghu.

How to build ERRest response for NSDictionary?

2014-11-21 Thread Jürgen Simon 
Hi,

I’m having some trouble implementing a simple function with ERRest. I have a 
method I wish to return a serialized NSDictionary from, not a serialized 
EOObject. Is that possible? The method could look something like this:

@GET
@Path(“/somepath/{id:Integer}/dailyReport)
public WOActionResults dailyReport(@PathParam(“id) Integer id)
{
NSDictionaryString,Object report = getDailyReport();

???
}

How would I go about building a response for this? Or do I need to implement 
another controller not inheriting from ERXRouteController for this?

Kind Regards,
Jürgen ___

Hi Jürgen,

there ist

   ERXRouteController.response(ERXRestFormat format, Object value, ERXKeyFilter 
filter)

that should do the trick.

Kind regards,
Ralf

Re: WebObjects application instances hanging - Deadlocks occurring

2014-11-21 Thread Ralf Schuchardt 
Hi Raghu,

as far as I can see, you have a log of lock/unlock operations with the 
EditingContext IDs and your original deadlock log with blocked thread names. 
But it is not easy to correlate those two logs, as the deadlock log is missing 
object IDs and the lock/unlock log has no thread names. I would expect there to 
be one more lock than unlock in the log, but it is tedious to find the right 
one.

There is the property er.extensions.ERXEC.markOpenLocks that may help, if you 
can get it to work. When the deadlock occurs the direct action 
ERXDirectAction/showOpenEditingContextLockTraces should show you a more 
complete picture of currently open locks and where the offending editing 
context was created.

Kind regards,
Ralf

 Hi Team,
 
 The following are the exceptions generating in the log files when we enable 
 the ERX logging, and we do not have any code in the Session.sleep method. And 
 some of our WebObjects application instances are hanging when some user load 
 (around 1000 users) are testing, when we look into the java process thread 
 dump there are deadlocks occurring.

Deploying to tomcat 8

2014-11-21 Thread John Huss 
FYI, for the few people who might be deploying with Tomcat:

In the recently released Tomcat 8, there is a breaking change that causes
WO apps which use the generated WOClasspath to break (fail to load).

The call to servletContext.getRealPath(WEB-INF) in WOServletAdaptor now
fails and needs to be changed to use an absolute path like so:
servletContext.getRealPath(/WEB-INF).

I don't see anyway to override the old class, so if you have this problem
you'll have to either replace WOServletAdaptor or use a custom web.xml file
that doesn't depend on WEBINFROOT being defined.  I love WO!   ;-)

John
