JMS: how to make child class loader (classes) available to parent loader

Hi,
Environment: oc4j 10.1.3.1 on SunOS 5.10
Our application (set up in an instance other than "home") sets up a JMS receiver, everything works fine to the point where the receiver receives the message but the message deserialization fails with the below error. Looks like the deserializer (loaded by the parent classloader sytem.root) is not able to load the class from its child code-source (one of my application libraries in WEB-INF/lib) I have seen a lot of documentation on how libraries can be shared between applications, but I haven't come across any that is related to my problem here. I have even tried adding the library in question to bootclasspath that did not help either.
How to get around this problem.
Thanks in advance.

How to make separate/individual text frame from one parent frame in indesign with javascript

Hi all,
Please suugest - how to make separate/individual text frame from one parent frame in indesign with javascript.
Thanks
Rohit

@Larry – ah, your interpretation could be the right one…
May I rephrase the question:
"How to split threaded text frames to single ones?"
"SplitStory.jsx" or "BreakFrame.jsx" under Scripts/Samples indeed could be the answer.
From the comments in the code of "BreakFrame.jsx":
//Removes the selected text frame (or text frames) from the
//story containing the text frame and removes the text contained
//by the text frame from the story.
//If you want to split *all* of the text fames in the story, use the
//SplitStory.jsx script.

How to make copies of delivered class/function module.

Hello All,
Can anybody tell me how/where should I go, to make copies of delivered class "CL_HRMSS_RECRUITING_WF" and the function module "HRWPC_EREC_CREATE_EREC_OBJECT".
Also if I am renaming with Z<my-class-name>, and using the method "CREATENBOBJECT" in my renamed class, will there be a problem with naming conflicts as "CL_HRMSS_RECRUITING_WF" already has the same method "CREATENBOBJECT".
Kind Regards
Srinivas.

hi Srinivas,
Can you tell me how I should create a package:
Ans:
1-> GOTO transaction SE80
2->Choose Package from the first drop down box
3->enter a name starting with Z or Y, press ENTER
4-> you will be prompted for confirmation to create a PACKAGE..Click YES..
Thats it.. package is created...

now go to attributes of each objects, which you had created as local, and change the package name from $TMP to the name of the package that you have created...you will be prompted for Transport request..create a request by clicking on the create button...save...
Hope this helps,

How to make BI 7.0 workbook available in analyzer

How to make a specific tab the active one when loading a page.

We need to be able to navigate between a set of pages all containing the same tabs. When going from one page to another, the active tab on the new page must be "the same" as the active tab on the previous page. In other words: there must be a mapping between one page's tab and another page's tab. To do this we need to tell the next page which tab to set as selected. Is there any way of doing this? Because we use a left-side that is tab-independant for navigation, we can not hard-code the tab-reference in the hyperlink. We have thought about using a page parameter saying which tab is active (by the use of a tab id), but it seems impossible to make a portlet change the value of a page parameter without doing so with an event. Because the content under each tab is passive, we can't send any events. Is there any other way of doing this?

When I click on the x to close a window, all windows are closing.
When I click on an active link to open a new window, nothing happens , only the already pen one gets replaced. It' s a pain in the butt, and there is no help or solution from FIREFOX, I studied all help resources. I will not attach screen shot to this mail, as that wouldn't help anything. My solution - I will work with SAFARI or SEAMONKEY instead and not use FIREFOX any longer.

How to make files stored in APEX available to non-APEX user?

Our application generates a number of files that are stored within apex_application_files.
Some of these are to be made available to a non-APEX application. We intended to do this through a granting access to a view to the non-APEX schema.
In order to access apex_application_files you need to set-up workspace security, etc. This can be done (details are in this forum), but relies on querying apex_applications - this view filters the applications using 'USER'. Therefore, it will only return applications where the parsing schema matches the user making the query.
So... how can we make some files available to the non-APEX schema?

If making serious use of file storage in the database then the best approach would be to store the files in application tables rather than relying on apex_application_files. This gives you total control over security, storage, associated metadata and so on.

How to make Federated Portal Network Content available in a Consumer Portal

Hello Experts,
we have the following situation:
We have two NW 7.0 Portals: 1 Main Portal on and 1 BI-Portal
We would like to do a remote role assignment via the Federated Portal option in the Portal, so that we can make the BEX-Explorer role from the BI Portal available in our main Portal.
I've already created a connection to the BI-Portal (Producer-Portal) in "Federated Portal" and have already registered the main portal as the Consumer in the BI Portal. I used SAP Help for that:
http://help.sap.com/saphelp_nw04s/helpdata/en/67/7e70424edcc553e10000000a1550b0/frameset.htm
Now I have the problem, that I can not find the remote role from the BI Portal in the Identity Management of our main Portal? Does anybody has a idea (or maybe a solution ) how to fix this problem? The SAP Help is not very helpful, it always deals with the same notes...
Regards
Andreas
PS: Of course u can earn points!!!!

Hi
first of all i would check that the SSO is working between the two portals..
Log into one of the portal.. Change the URL to the other portal. If you have to log in, then there is a problem with your SSO. Remember to have enough permission on both the portal.
If that works, then log into the consumer portal and check what you find in the portal content of the producer portal.
Let me know the result, and I will help you further..
Best Regards

How to make an untwisted camera profile available in LR 4.4?

I have downloaded dcpTool from http://dcptool.sourceforge.net and generated the untwisted versions of all the Nikon D700 related camera profiles (Adobe Standard, Camera Standard, etc.) that come with LR 4.4. Since the structure of the camera profile filenames seem to be important, for each file I kept the original name but added a distinction to its end (e.g. Nikon D700 Camera Standard UT.dcp).
According to the information I have collected, 'installation' of these profile versions would be as easy as copying them into the same directories where the original profiles are. Unfortunately LR 4.4 does not bring them up in the Camera Calibration module.
How should I 'install' these profiles?

Thanks again for your very useful advice. You gently explain why my idea is groundless. You are right, it is better to stay on ground.
I changed to LR recently. So far I have used only the Adobe Standard profile, but I am not very pleased with it. A few days ago I started fiddling with other D700 profiles, without any convincing color rendering improvement. This is the reason for entering the camera profiling world.
As my username reflects, I am a hobbyshooter. Most of my pictures are taken when travelling (landscapes and cityscapes) but I also shoot at family events and parties.
You have made me even more curious about the ColorChacker based profiles. I hope they will solve my main problems: skin color, the vivid reds of Nikon, and the formerly mentioned hue twist. Nevertheless, I am afraid that finding the right color rendering balance for my typical environments (particularly for indors with totally mixed lighting) will not be easy...
I am also thinking of reprocessing roughly two thousand pictures, taken years ago with D200 and D300. Do you have any suggestion how to get nice 'generic' profiles for the given camera+lens combos, which I do not have these days, so creating their profiles with ColorChecker is out of the question for me?

How to make more hard disc space available

Working in iMovie, I ran out of hard disk space so I cleared Trash and moved everything that was not essential for the task in hand onto a memory stick, including most applications such as iWork. However, no matter what I removed or cleared I was unable to recover half the 55GB nominally available on the McIntosh HD. What will be tying up the 25+GB of the nominal 55GB available and can I free it up?

actually most of the data is in the iMovie event, not the project. The project is small until you "Share" and then it contains a copy of the QT movie, that you can only see if you right click (control click) the project and "show package contents". you can toss those Qt movies (you can always make them again) if you want and they are there.
If you are sure you will never want the unused parts of the clips (stored in iMovie events) again, go to "move event to trash" and you will be prompted to delete
"delete unused" or delete entire clip. If you delete unused it will take a while to process, but will then trash every clip that you didnt use and any part of any clip you did use , keeping just that parts of the clips you used in your project. Then you will have to get them to the trash through the events browser window, then empty the trash. The other way is to choose "space saver" and that will toss (for all your events, not just the one you highlight) any clips not used, leaving the clips you do use alone, a safer way to free up space, but wont free up as much space.

The procedure that invokes the child procedure is effectively dormant while the child runs.
Plus there is no easy way to know when 5 seconds has elapsed.

How to make Spotlight search always on available/mounted shares?

Hi all, is there a way to configure spotlight on our Leopard Clients to always search our spotlight enabled shares on our leopard server?
The only way we can do this until now is by manually selecting to search "Shares" in the finder. We would appreciate the quicker way via CMD+Space to find files also on our shares.
By default, CMD+Space seems to search only on the client.

I finally experienced the "Spotlight just stopped" issue after a year and a half of flawless use. Here is how I fixed it.
Went to System Preferences, chose User Accounts, and created a new account. Then logged into the new account. Spotlight was working, logged off new account then back into the original account. Spotlight was now working again for it.
My original intent was to just see if it was my user account that was having problems but it turned out to be the fix.
Maybe it will work for you and others.

Spry MenuBar - IE6 - how to make that submenu is shown above the parent element

Hi you all,
I need the menubar to open the submenu above the parent element.
Here´s what I did:I inserted a spry menubar and the only css-change I did was the one shown below in red "botom: 2em;"
This works exactly as I need it to - in Safari, Firefox and Opera.
In IE6 however, the submenu is shown far below the parent element. Is there a solution?
Greetings from Germany
Alex
/* Submenus should appear below their parent (top: 0) with a higher z-index, but they are initially off the left side of the screen (-1000em) */
ul.MenuBarHorizontal ul
    margin: 0;
    padding: 0;
    list-style-type: none;
    font-size: 100%;
    z-index: 1020;
    cursor: default;
    width: 100px;
    position: absolute;
    left: -1000em;
    bottom: 2em;

thank you very much, Nancy!

Possibly. It's hard to tell without seeing your page, though.

The position of Spry Menu Bar submenus is controlledby the margin
property on submenu ul tags.
1. Locate the ul.MenuBarVertical ul or ul.MenuBarHorizontalul rule.
2. Change the margin: -5% 0 0 95%; default values to the desired
values.

Also, look through the CSS coments for IE hacks. Often these
workarounds for older browsers can be commented out or deleted.
Test before you delete anything permanently.
