How can one servlet (ActionServlet) effect another servlet (AxisServlet)...

Recent issue is driving me batty. Suddenly started receiving exceptions in app server logs (tomcat a la jboss)...
Servlet.service() for servlet AxisServlet threw exception
java.lang.IllegalStateException
org.apache.catalina.connector.ResponseFacade.setBufferSize(ResponseFacade.java:220)
org.apache.axis.transport.http.AxisServlet.doPost(AxisServlet.java:610)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
org.apache.axis.transport.http.AxisServletBase.service(AxisServletBase.java:327)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
After many many hours of research, appears that I get this exception if a specific struts action (one of several) executes at the same time as a SOAP call to the AxisServlet. It ends up causing the return of an empty dataset to the calling SOAP client (and giving me a bad headache to boot).
Weird.
The actions that appear to cause this aren't special in any way (not any different than other actions in my application), but I am obviously missing something. I have a suspicion that the struts actions that cause this are all chained events (one action calls another which leads to a JSP....but can't completely confirm).
Any thoughts? How can the activities of one servlet effect another such as this? Yes...they are in the same war/ear......and they probably share some common classes.....
For the record...Jboss 4./tomcat 5.5 Struts 1.3X and Axis 1.2 (although have tried 1.4...same results). Java 1.5 on FreeBSD 6.0.
Any help would be appreciated.

If the other servlet is in a web-app in the same container, you can use RequestDispatcher, if not you would have to use a URLConnection.

How can one process "ask" if another process is running?

Hi there,
This is a very general question: how can one process "ask" if another process is running?
In other words, what 2 process share together.
Thanks for any help.

This code will print all active Threads.
Look at at the API docs for further information.
ThreadGroup tg=Thread.currentThread().getThreadGroup();
        while(tg.getParent() != null)
            tg=tg.getParent();
        tg.list();

How can I import contacts from another AIM account to this new one??

Hi,
Use AIM for Mac and use the Export and Import features.
Other than that it is a question on making sure every Single Buddy has more than just their Screen name in the IChat Address Card so it is added to the Address Book and dragging them back from there

How can I use After Effects filters on a whole sequence without getting stuck in After Effects?

It appears that, with the options that are visible to the user, Dynamic Link only goes one-way and can't make round trips from Premiere Pro to After Effects and back again. If I send a sequence to After Effects, that part works fine and I can do what I want and save the comp. However, even though the comp appears as an asset in Premiere Pro, I am not allowed to do anything with it. If I try to drag it to a new sequence, it just says no. If I click "Create Sequence from Clip" it creates an empty sequence.
So how can I use After Effects on whole sequences/tracks instead of just on a clip-by-clip-by-clip-by-clip-by-clip basis? is this possible? For instance, if I have a whole sequence where I've neutralized the white balance, I might want to apply a warming filter to the whole thing as a unit. That would be really painful with even a few clips to keep doing that again and again, and if you want to modify it slightly you have to do it over and over. If there is a way to do that through Dynamic Link through some hidden option, what happens with the audio? Would I have to cut it out of the lower sequence and paste it into the higher sequence with the After Effects comp as a video track?

I'm not an Adoby guy, hence you may ignore my reply, but Adobe Dynamic Link is obviously not just one way ticket and in most cases works just fine.
You have already been explained by J-MS and tclark513 how to properly use it and which pitfalls may occur.
So as to apply an effect onto a whole sequence or a group of clips you need to either nest them in PrPro or pre-compose them in AE. Then just apply an effect (or several ones) onto that composition.
So, if you nest clips in PrPro, select your nested sequence in the timeline, right-click and choose 'Replace with After Effects Composition'. Done! Your dynamically linked AE composition is in the right place in your timeline and in your Project panel as well. If you can not treat it as an ordinary footage, there are obviously some mistakes in your workflow.
If you didn't nest your sequence or a group of clips in PrPro before replacing them with AE composition, you may easily do it within AE. Just select all the layers in AE composition and choose Layer -> Pre-compose... (Ctrl/Cmd+Shift+C) Done! Switch back to your Master comp and apply your desired effect(s)
You may loose some effects or/and transitions while travelling from PrPro to AE via Adobe Dynamic Link, whereas you don't while travelling back
(If you start building your AE composition from scratch right in AE and then need to import it into PrPro, DO NOT export one as PrPro project out of AE, but rather choose Adobe Dynamic Link -> Import After Effects Composition... within PrPro)
P.S. And yes, submit a feature-request so that Adobe will convert 'Transparent Video' into fully functional 'Adjustment Layer'.

I hope some one will help me by anwsering my question.
Than you for time.

If your system does not meet the minimum system requirements you have to go back to a version that does. Try the direct download links you'll find here.. CS5 comes bundled with CS4 for AE which is the last version to run on a 32 bit system.

How can I install Premiere in another computer

How can I install Premiere in another computer, if my main computer does not work. The service is paying monthly.

As far as I have understood it you can install PP on as many computers as you like, but only two can be active at the same time. So if you have installed it on just one computer you should have no problems installing it on a second one. If you want to install it on a third, you would have to deactivate one of the other previous installations to get it to run.

WHAT'S THIS EFFECT CALLED? OR HOW CAN I GET THIS EFFECT?
first of all i don't know what's this kind of photo effect called, i just describe it as bright, clean and w/o lack of contrasts
secondly, i wanna learn how to achieve this effect.....really don't know how
need help here....
btw i don't know where to post this post....so i just start from here =)\

For my part you are welcome, Lisa.
then what about the color tone here? it's very pure and clean, a touch of blue i think, is it from the nature light or from photoshop effect?
The colour tone is (hopefully) a result of the nature of the natural light faithfully reproduced by the high quality of the camera (and film if relevant).
You will get quite different and sometimes rapidly changing tones of colour depending on the natural light; this is different for different times of day, different directions, different weather conditions.
Just to mention a few comparisons, the warm light from the setting sun is quite different from the cool light from the clear bright sky through a (high) window to the north at noon, and the light of the sun can be changed immensely by the huge white (or grey) filter sometimes applied to (parts of) the sky.
You may do many things in Photoshop, but photography is still an art form, not just cheating, at least for some.
I believe one of the real provings of cameras/films is the ability to reproduce the delicate but profoundly different tinges in snow on a clear day.

As of EHP3, you could still install some EHP components. On an ERP 6.00, you could just push SAP_APP to 6.03 and move on. Now if you want another component in your system with an EHP4 version, you can't have some components at EHP3 and some at EHP4. You would install EHP4 for the new component you desire updated and part of the work will be to also update SAP_APP to 6.04.
EHP4 is an UPGRADE process, with shadow instance & all the joy of an upgrade process. You can either run ressource minimized or downtime minimized. In resource minimized, the shadow instance runs on the same server as the main instance. Downtime minimized allow to run the shadow instance on a separate / new server. Anyway you go, you will always have a "Downtime Phase" when you bring back the updated components from the shadow instance toward the real production one.
As with any UPGRADE project, the benefits of installing EHP4 for your business has to weighted against the downtime cost.
Our tests so far on small systems (few data, few users, 120GB database) show ~3 days process from EHP3 to EHP4 (all components) with a downtime phase of about 22 hours using the "resource minimized" path, i.e. shadow & main instance on the same server (4 CPUs, 16GB RAM). Until you give a try at your Sandbox or DEV systems, you won't have realistic figures for your environment.
Good luck!

How can one change the channel of a screen control within Mainstage?

The issue that I'm having is that some 3rd party apps (Dimension Pro in particular) seem to receive Sustain (64) messages on only Midi Channel 1
I'm using a multi zone controller, with sounds set in MainStage to respond to different channels. I've got it all working well except . . Dimension Pro won't "see" a controller message if it's sent from any channel other than channel 1.
I was even having the same problem with certain sounds in Kontakt.
So the question is . . how can one shift the channel of these messages over to channel 1?
Better question, how can I get Dimension Pro to respond to a controller on a channel other than 1, but I suspect this is not the forum for such questions!
Thanks in advance,

You may be able to achieve the desired results by a different method. I have an Axiom, but I don't assign zones in it. I just send one zone to Mainstage and handle it all there. You can layer and or split a practically unlimited number of instruments and assign screen controls easily. You probably want to set up all screen controls at the concert level in layout mode. You can later override concert mapping in individaul patches if you want. For instance, you could use an expression pedal for volume(7) on one patch and for modulation(1) on another patch. You can send that control to one instument channel strip or you can choose to send to all. To do this, select a screen control in edit mode. In the screen control inspector, check the overide concert mapping box. You will then see two additional tabs-mappings and unmapped. Select the mappings tab. In the mapping list, double-click "Unmapped". You can the map the screen control to any single instrument channel strip in this list or send to all. Select one and then choose a mapping destination. If you want to map expression to one instrument and not others there's another way. Select an instrument channel strip, then selct MIDI input in the software channel strip inspector. Check the filter expression box. This instument will now not respond to expression, but the other intruments in this patch will. You can filter some other events on this page. The layer editor tab allows you full control ol splits and layering options of all your instruments in this patch. Hope this helps.

How can one convert a picture to 1080 pixels in height at 72 dpi and retain the aspect ratio?

How can one convert a picture to 1080 pixels in height at 72 dpi and retain the aspect ratio?

The ppi has nothing to do with this. It will stay at whatever it is.
Go to image>resize>resize image, turn ON Resample image and enter 1080 for the height, making sure to leave constrain proportions turned on. Don't mess with the ppi setting.
If the image is set to another ppi setting, then after you're done with the above, go back into that window, turn OFF resample image, and set the ppi to 72. PPI only affects the inc/cm measurement.

How can one develop "view only" client applications in Lookout?This is to develop remote monitoring without control functionality.

How can one develop "view only" client applications in Lookout?This is to develop remote monitoring without control functionality.
We have 10 Client Nodes in the field and we need two "View Only" functionality in Client machines located on Supervisory Desks.

I have done this. There are many ways to approach this but I will offer what I think is the easiest. This will work ONLY if you have been assigning security levels to your objects (objects that actually control devices in the field) greater than zero AND allowing a security level of zero to view all panels. When I develop interfaces I do this just for creating a non control client.
Basically, you remove all users from the Lookout client in the user manager. You will not be able to remove the built-ins, "Guest" and "Administrator". Now when the end users tries to login using his normal login he will be denied. Consequently, he will not be able to control. But, he will still be able to view all the information since a no login can view a panel with a viewing se
curity level of zero. You must ensure any pushbuttons that are used to open panels have a security level of zero.
Now you can copy this security profile by finding the lookout.sec file and copying it to another non-control client computer. In Windows NT this file is located in the system32 directory.
There are many other ways but I find this the easiest.

Tommy Scharmann
