WebLogic and AspectJ Load Time Weaving

I have tried to weave some classes running in a WebApp inside weblogic using AspectJ and Load Time Weaving, as explained here:
http://www.eclipse.org/aspectj/doc/released/devguide/ltw.html
I run WebLogic using -javaagent:/pathto/aspectjweaver.jar
and providing inlide declaration of an Aspect in a aop.xml configuration file.
I have tried to expose my rudimentary setup here
http://www.javamonamour.org/2011/12/weblogic-and-aspectj.html
Can someone help me out? I have very little experience with AOP, I am sure I have missed some concept like scope, activation etc...

Hi, yes. Configure the pool to have an initial capacity of zero. Then it will
deploy and not try to make any connections. It will only try when/if
it is asked for one at runtime. Even if the DBMS is not up, the
DataSource will just throw an exception until the DBMS is up.

AspectJ load time weaving AnnotatedNoClassDefFoundError

I am trying to use AspectJ load time weaving on an application running on OC4J 10.1 on JRE 1.5. I get AnnotatedNoClassDefFoundError with Missing class: org.aspectj.runtime.internal.AroundClosure message.
Here is what I am doing:
1. Starting the server with JVM argument -javaagent:aspectjweaver.jar to enable AspectJ load time weaving.
2. I put an AspectJ library MaintainJAspect.jar under j2ee\home\applib folder.
3. I put the aspect defined in aop.xml at j2ee\home\applib\META-INF\aop.xml .
The aspect defined in aop.xml is properly weaved into the application class (I can see in the dumped source). But when the application is running, it fails with the message pasted below.
My question is, while it says that the missing class is available in oc4j classloader, which is parent of system and application class loaders, why is it not available to my application?
Thanks in advance,
Choudary Kothapalli.

Not sure what you mean by "support". AspectJ rewrites bytecodes so the VM will just execute them. You'll probably encounter increased memory usage with load-time weaving as class loading/initialization occurs in Immortal memory. Also load-time weaving won't be compatible with Java RTS's Initialization Time Compilation (ITC) feature ... or at least not the pre-initialization part. It's likely that no-heap threads won't work well running weaved code if there are any references back to heap-allocated AspectJ runtime objects, and similarly (like most libraries) it's not likely to work from scoped memory.

Single page application and page load time

I'm trying to instrument a "single page application" with Application Insights but it seems that there is not way to provide manually the performance data (page load time) when invoking the logPageView() method.
The single page application has a "unique page" and all views are displayed using internal routing feature without refreshing the main page once it is loaded. So the logPageView() method is invoked multiple times: one of each displayed view.
It means that the built-in performance counter (netCon, ..., ptotal) based on window.performance.timing.* do not make sense for this type of application, that should be based on manual computation of the time needed to render each view.
Is there any method to provide manually this information using logPageView() or separate method ? If not, is there any idea to fully support in the future the single page application ?
Thanks in advance,
Maurizio

Hello Maurizio,
Do you still have the same issue with the latest
AI in Azure Portal?
There should be new API layer with the ability to submit custom properties and metrics. This might work well for you scenario. AI nugets are still in preview, please, use "Show Prerelease" in VS when adding those.

UI5 chart and grid loading time

Hi Experts,
I m working on UI5 chart and grid in SAP MII 14.0.
When i load my pages,it takes lot of time on intial load.
Is their something which i missing in my code or any property i need to set?
Thanks in advance.
Please guide.
Regards,
Neha

Currently Being Moderated
Hi Ria,
Thank you for quick reply.
If i load my page intially,it is taking 1.20 mins and reloading of Ui5 grid and chart it is taking hardly 10 sec.
If i test chart/grid seperatly in page,it is taking 55-57 sec to load intially.
Regards,
Neha
Hi Neha,
As per above response, I dont see any chances where your transaction runs in 5-6 secs but the chart loads in 55secs. Quite strange, how are you rendering things on page, are you using an applet?
Usually time a applet takes is directly proportional to the time require for background logic, and the factor is mostly 1. So the moment your back logic executes, your chart loads.
Please give some insight on the logic you use while rendering the chart, so that it becomes easier to guage the case.
Thanks again!!
Nice time,
Swaroop

Brand new iMac, and the load time for internet use is very poor

Brought my new iMac home today. 2.7 GHz intel core i5
Got it set up with my wireless and i am very unimpressed with the internet and loading speed. My phone, 1 lap top, and 1 ipad use wireless in our house along with the iMac. i have a cisco linksys E2500 is that sufficient enough all of my usage? No gaming more than what a todler would play on. Basic internet use and editing pictures.
My question i guess is, is it my router or are iMac's just not that fast?

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Syncing and App load time

1) Regularly used apps are taking longer to open. For example when I open the "messages" app it lags for a couple seconds before displaying my texts. I deleted most old texts hoping that would speed it up, but it didn't. I have done the "home+power" button held past the red slider.
2) When cleaning up my iphone, what items should be considered for deletion other than the following:
-Texts
-Mail - inbox and sent
-Safari cookies, cache and history
-Any apps that log events (e.g. Things archives completed tasks)
3) My iPhone takes forever to sync now. Is there a way to modify it so it only backs up new items instead of backing up everything every time I sync? I have "calendar" and "contacts" checked to sync. But even when I haven't made any changes to my calendar or contacts ,it still goes through the whole syncing calendar and contacts process. Why?
4) I have to wait until the sync process fails to read how much space is required to sync all my selected items. Is there a way to see how much data I have selected to sync beforehand so I don't waste time syncing twice?
5) Does the iphone have moving parts? If not, does this mean it is not susceptible to fragmentation?
Thanks in advance guys.

Do you have a lot of photos stored in the camera roll? If yes, see this article: http://support.apple.com/kb/HT3603
Did you already restore your phone? If no, restore it "as new phone" to make sure no corrupt data is copied back afterwards. Backup and restore: http://support.apple.com/kb/HT1414 and http://support.apple.com/kb/HT1766
Connect your phone and check the status bar in itunes to see if you have a huge orange "other" section on your phone. If yes, this could be corrupted data. Backup your phone manually by right clicking on it in the device list and choose backup. See what's part of the backup here: After that restore your phone
Does the iphone have moving parts? If not, does this mean it is not susceptible to fragmentation?
The iphone has a flashdrive inside and MacOS is not susceptible to fragmentation

Qt4 updated to 4.8.7: Slow text scrolling and higher load time.

System is fully upgraded, and i just noticed that every qt4 application has become incredibly slow when using QT_GRAPHICSSYSTEM=native (slow dolphin scrolling, slow konsole scrolling)
It is probably related to text antialiasing, because if i disable subpixel hinting in konsole, it start to scroll fast.
Reverting back to 4.8.6 fixes it.
I want to use native instead of raster because:
1) when used remotely via x2go and ssh, qt apps are very fast using QT_GRAPHICSSYSTEM=native
2) with QT_GRAPHICSSYSTEM=native one is able to retain RGB subpixel hinting even over trasparent windows.
I'm using nvidia-340xx 340.76 with a geforce 9800GT and freetype2-infinality 2.4.12-2 if it matters.
Anybody can help please?
-EDIT
This does not seem to be related to an update of the xorg-server, nor to the graphic driver; i notice the same behaviour when using a remote (fast) vnc connection.
I bet it is a QT4 bug; someone could test please?
Last edited by kokoko3k (2015-06-19 15:56:35)

It is not just the text scrolling under native graphicssystem to be slow.
All qt4 apps with text edit widgets are now slower to open, even with raster graphicssystem.
Gambas3 ide takes 6 seconds to start; on 4.8.6 it starts in 2 seconds here.
Just reported both:

Load Time and MP3

Hi,
I am revamping a program that was originally done in Captivate 3. All of the sound files were recorded using another program and imported. They were originally in WAV format. The file size is huge on this thing and the load time is (to me) excessive. I eliminated a couple of the videos and coverted about 50% of the WAV files to MP3 and reloaded them. I also made sure I cleared the unused items from the library. Unfortunately the CP file size has remained the same and the load time is still long. Can any of you give me some thoughts on how to cut this thing down?
Many thanks in advance for your help!
Gary

Hello,
How did you check the CP-filesize? Can you please save the file, close Captivate, and then reopen it with the file? Have a look at the filesize then? The decrease of file size is not immediately visible, but do know that clearing up the library, and certainly deleting video/audio does decrease the filesize really. WAV-files will be converted to MP3 anyway when publishing to SWF, unused items in the library do not have any influence on the SWF-size either. Perhaps you are not talking about the CP-filesize but about the SWF-size (because you are referring to load times). To decrease the filesize for the SWF you'll have to look to other means: decrease the resolution (if acceptable, by downscaling), decrease the JPEG-quality, decrease the audio quality. To make the loading time smaller you can also change the percentage to load before starting to play the SWF (default=100%, see Preferences, Project, Start and End).

Iceland site - load times ok?

Here is a site from our trip to Iceland. Are the image and movie load times ok?

Of course, any design suggestions welcome. Thanks.

TomBud, I know the corners look bad on a few shots. Believe me, I was kicking myself when I looked at the video for not being more careful. I tried putting in a matte in the corners, like little triangle pieces, but I think it detracted from the video more than the blemishes.

Slow load times on AU sites?

is anyone still experiencing slow load times on AU sites, apparently this is resolved but I just emptied my cache and checked load times on half dozen sites. Still very slow!

I just loaded http://www.prettypollution.com.au/ and it took 17sec.
Got similar time for http://www.designexperts.com.au/ as well. So, although not very fast it's much better than what you’re seeing. Could be something in the node you’re being routed through.

Sudden increase in webpage loading time

I´ve had a Mac Mini (1 Gig of RAM) for over three years. It´s connected to a router Zyxel Prestige 660HW-61 via Ethernet. My internet connection is 3 Mbps down. Web surfing has been fine until last week when I noticed a sudden and dramatic increase in the time web pages took to load, to the extent that they fail to load more often than not.
When browsing threads for possible causes, I found this one: http://discussions.apple.com/thread.jspa?threadID=2059511&start=0&tstart=0
As suggested by Boece, I restarted my Mini and run nothing but Safari (4.x) and Activity Monitor to watch the outs-to-ins ratio while Safari tried to load a page. Page outs remained at 0% for the duration of the test (around 40 minutes testing sites such as IMDB and Youtube and running a few google searches)
Next I installed Firefox (3.5) and Camino and run the same test to see how my DNS setup performed. Page outs remained at 0% again and page-loading time was painfully slow with the new browsers.
Time to switch over to OpenDNS. I installed the OpenDNS domain name servers in both the router and the Mini instead of those provided by my ISP, restarted the Mini and run the same tests with Safari, Firefox and Camino. Unfortunately, I didn´t notice any improvements at all.
I´m not aware of any anti-virus or malicious-website protection software installed on the Mini or in the browsers.
I don´t have MS Office installed and only one Dashboard widget (iStats Pro)
Web surfing is fine with my Dell laptop and donwload speeds with the Mini, though I´ve been unable to test them via websites (pages failed to load), seem fine after having downloaded a few bittorrent files using Transmission.
Whatever the problem, it also applies, perhaps not surprisingly, to MacTubes. It fails to both play and download youtube videos.
Any other suggestions? Thanks in advance for your help.

Vo initialization and lazy loading.

I need to execute some initialization work then a VO is loaded.
To do that work I need the AM and then I can't do this work in constructor.
My implementation was realized doing that work in the AM prepareSession method wich loops all VO and execute an init method : all works OK.
Now my project is growing up and the load time is very long then I thought I can use lazy loading.
Doing that, however, my initialization proces fails because in prepare session no Vo is present and then I don't know when the VO is loaded.
Is there any event in VO called when the VO is loaded ?
Could someone suggest a cleaner solution to my initialization problem ?
Tks
Tullio

Maybe you could try to intercept findViewObject() in the AM, keep track of the not initialized VOs and perform the initialization stuff for a VO first time it is used (i.e., when created).
Nevertheless, this is not easy management in lazy loading - you will have to "manually" load related objects (i.e., VLs).
In 9.0.3/9.0.4 we finally gave up. Didn't check if in 9.0.5 this behaves better...
HTH,

Page not found, slow loading times CC Files

Hi,
Two weeks ago I reported that there were CC files problems like 'page not found' errors and slow loading times and pages not even showing anything. Those problems were temporarily resolved but are back as of today.
Please fix this because for me this is not workable and I guess for many others. I've already moved part of my design files away from CC Files and am now reaching the point were I want to abandon this beta-ware altogether.
I'm living in Europe, maybe this gives additional info. Maybe server problems only in this continent?
Thanks for looking into this.
Jan

So what product would you advice me to file this bug report under? There is no Creative Cloud Files entree or similar.
I'm not sure I'm taken by Adobe support channels policies. if I tweet a complaint some employee tell me I'll be called back by support. Instead of being called back I get asked per email to report on the community forums, when I post on the forum someone tells me to file a bug report. Ehhh...
Time to move on.
