Working with custom logger in my application

HI all,
I wrote a simple application work as a logger. Basically a class used to record logs of another application. It's working as I aspect. But my problem is this.
Say I'm going to use my logger in an application, which has around 10 classes. From each class I want to send a message to record. So I need to instantiate my logger class on that 10 classes. Is it ok? If it's bad practice, what is the simplest way to do it.
Thanks a lot. :)

I've solved this my self. Thanks for all who spend there time to read this post. :)

Not able to work with customized Java roles which were edited in ABAP stack

Hello All,
I am trying to copy standard roles into customized roles (i.e. Z roles) using PFCG in XI system. All ABAP based roles are working fine, but all JAVA based roles are not working. I generated profiles as well. And I check all the authorization objects in both standard and customized roles. Everything look same but customized roles are not working.
And when I check the logs on JAVA stack I found the error which says " User XXXXXXXXXX IP address HTTP request processing failed. HTTP error [403] will be returned. The error is [You are not authorized to view the requested resource.No details available]."
I thought there might be any Jco RFC connections missing between the stacks and I tried to check in Visual Admin, but I was not able to find much info regarding these roles.
Am I missing anything or is there any other way for these roles to make customized roles.
And can any one tell me how to run a trace for JAVA stack activitites as we do in ABAP using ST01. Any help will be rewarded. Thanks in advance.
Regards,
Farooq.

Java roles work with influence of permissions in Application Server which we call actions in UME. As you are aware in PI user master record will be in ABAP stack. So the roles in ABAP stack will be having only RFC connections to JAVA stack for the specific JAVA based role. So you need to edit the permission on Java App Server. For that you need to log on to server through visual admin and then go to services and you will find the standard groups assigned to actions. But I dont remember that under which service you will find them
Under that service you will find some 200 actions. And you have to add the name of the custom created JAVA roles on ABAP to all those actions where you find the standard roles. And its a very very lengthy procedure. So SAP advice to go for customized ABAP roles and Standard JAVA roles.
Hope this answer clears your query.

Discoverer Viewer/Plus does not work with Custom EUL owned by APPS user

I am facing a unique issue with one of my customers. They have a custom EUL named XX_EUL_US and this does not allow connecting through discoverer viewer or discoverer plus.
I have worked with custom EULS before at other customers and this was never the case. I am being told that this issue is happening as the EUL owner is APPS instead of some other user. Is this the case? Can discoverer viewer not be used with EULs owned by apps user?
Please not that the Default EUL in ICX profiles is set to this EUL and no other EUL profiles are set.
Appreciate any thoughts on this.

Hi,
I am not sure what you mean when you say you have a "custom EUL named XX_EUL_US". The EUL table should be created in a schema named XX_EUL_US. This will then be the EUL owner. You will then need to connect to Discoverer Administrator as the EUL owner and grant privileges to Apps users and/or responsibilities.
The user should then be able to connect to Discoverer Plus/View using their apps username, responsibility and password.
To be able to connect directly from an apps menu you need to have the ICX parameters set correctly. The ICX: Discoverer Default End User Layer Schema Prefix should be set to XX_EUL (without the _US). The ICX: Discoverer End User Layer Language Override should be set to US or not set at all.

Is it possible to work with different languages in different applications?

Hi,
is it possible to work with different languages in different applications?

Can Actions Menu of Interactive Reports work with Custom Authentication?

My testing is leading my to believe that Actions Menu do not work with Custom Authentication (but only work with APEX Authentication) in APEX 3.1.2? If that's true then is there a work around to this?
Just to clarify, I've posted/asked this question twice before:
1) Re: Actions Menu in Interactive Reports does not sort, filter, select cols etc
2) Interactive Report actions don't work for users (i.e. for non-developers)
But I've come to believe this is the main problem. I just don't know how to resolve/work around this?
Thanks for any help.

I haven't setup a sample because my custom authentication is using LDAP authentication. I'm not sure how I can replicate that on the samples server?
I'm using LDAP authentication with a Page Sentry function. My further testing reveals that the Page Sentry function is setting the APEX variable user to NULL (ie blank) whenever there's any code in the Page Sentry function box. PL/SQL code as simple as
BEGIN return TRUE; END;
in the Page Sentry function box sets the "user" is set to <null>. When the Page sentry function box is left empty (no code specified) it sets the "user" properly after authentication against the specified LDAP directory.
What all this has to do with Interactive Reports...
It seems like when the user is NULL it messes-up Interactive Reports that are stored in the flows database. Although it shows the default report properly, but no runtime interactive actions (filtering, sorting, column break, etc.) work.
Can someone please correct or confirm this?
Thanks.

ADF wont work with custom LoginModule! Question for Mr. Nimphius!

ive setup login module as shown in:
http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm
code:
actionContext.getHttpServletRequest().isUserInRole("Administrators") works! but i also want this code to work in ADF:
appmod.getSession().isUserInRole("Administrators")
with default loginmodule "oracle.security.jazn.tools.Admintool" everything is ok! i can get roles in adf but with custom login module i cant!
in ApplicationModule config i have setup
jbo.security.config =
jbo.security.context = oracle.security.jazn
jbo.security.enforce = Must
jbo.security.loginmodule = oracle.sample.dbloginmodule.DBTableLM.DBTableLoginModule
please help!

thank you very much for the reply!!!!
i did what you told but no luck... :(((
i still can not get user role from application module!
this code:
if (AppModule.getSession().isUserInRole("Administrators"))
System.out.println("User is in role! ");
simply does not work!
ive tested on standallone oc4j, ive tested on embeded jdveloper 10.1.2.1 !
i get NullPointerException at at oracle.jbo.server.security.jazn.JboJAZNUserManager.isUserInRole(JboJAZNUserManager.java:113)
the thing is that i can use isUserInRole() from request but i can not from application modulle....
...ive lost hours in decompiling and tracking down ADF code just to realize that there is no way to use custom login module with ADF because the thing is hard coded to use xml or ldap..
the only way i see how to solve the problem is to extend oracle.jbo.server.SessionImpl
and override
getUserRoles()
and
isUserInRole(String s)
i can substitute session class with my own by setting
SessionClass = oracle.jbo.server.ExtendedSessionImpl
in file jboserver.properties (which is inside bc4jmt.jar)
the easier way is to write my own function isUserInRole() in EntityImpl... i always can get user principal name with AppModule.getUserPrincipalName()
what do you think?

Linking of SRM OBN with Custom SRM POWL WDA application

Hi All,
We have our Producer portal with version 7.0 sp14 and Consumer with version 7.4 sp05.
We have "Check Status" a SRM Standard POWL application integrated in portal and all the Navigation OBNs are working fine with it.
our ABAP team developed a custom POWL application only for Buyers to show the shopping carts.
We have successfully integrated the POWL application in SRM portal.
we have added the iView to Role and added the navigation folder with all BO objects for OBN.
however when we assign the role to user, we are getting Portal Runtime Error.
Please help us on how to link OBN Business Objects with Custom POWL application.
Thanks in advance.
Regards,
Vijay.

Hi Vijay,
Your portal versions are not compatible. Please check note 1295662 - 'Interoperability between 2 portals in FPN environment' where you will see that in order to setup a federation between a 7.4 portal and 7.00, the 7.00 system must be on at least SP25.
Thanks and regards,

Look Up function is not working with custom dictionary - How can I solve this?

Hi everyone,
I recently installed a Chinese-English dictionary known as 小词典 or Xiao CiDian using the .mpkg file that I downloaded from the website (here's a link: http://xiaocidian.com/). The dictionary package was added to the native Dictionary application on my Mac. When I go to the Dictionary application and search for Chinese words, there are no problems – results just come up as they should. The website claims that the Look Up function should work with this dictionary as well, and that I should be able to look up the definitions of any Chinese words that I come across (which makes sense, seeing as it's integrated into the native Dictionary application). The problem? It's not happening. I've tried all the ways that I have found to get to the Look Up pop-up dialog box – Ctrl-Cmd-D, right-click and the Lion three-finger double-tap gesture – but all that ever happens is that the dialog box comes up, saying "No results found". Does anyone know why this is happening? Should I try reinstalling the dictionary? Thanks in advance to anyone who can give some advice.

If you don't get an answer here, you might want to search/ask in the Chinese Mac list:

Also, use the FM that MAX has if you have to work with files on application server by replacing code in the above logic at appropriate places, like replace
cl_gui_frontend_services=>directory_list_files
with the corresponding fm
and replace cl_gui_frontend_services=>gui_upload
with OPEN DATASET...
     CLOSE DATASET...
logic.
Hope this helps..

Working with Test/Production environment as application sets

Hi to all,
does anyone here works with a Test/Production environment system?
We've got a single system (2 machines, one for the DB server, one for BPC), and we were thinking on making 2 application sets: Production and Test. While most of the things is easy to migrate from one system to the other one (since almost all of them are files), what worries me a bit are dimensions and some configurations of the application, security, and so on...
Has anyone experience about it? Would you suggest it?
Thanks
Daniele

Hi Daniele,
As rightly suggested, duplicating an appset can be easily done on 2 different physical systems. In the source, you run the server manager and take the backup of your appset. Then copy the back up folder from source to the destination through the network. Again use server manager to restore the appset from the backup folder. With this process, everything will be migrated and you dont have to worry about anything.
The point of worry is, lets say you have moved everything to the PROD and then you continue doing development in DEV and then you want to move these changes also. Now, again taking backup and restoring will not be the right option because by now, there might be some PROD data available. and if you restore again, then all that data will be lost. So, after the first restore, whatever you are doing in DEV, keep a note of all that. So, that the same thing can be replicated in the PROD system.
Hope this helps.

BT848 TV not working with custom 2.6.22 kernel

Hi,
I installed a custom compiled 2.6.22 kernel (built the traditional way, using menuconfig in /usr/src/linux-2.6.22) but then tvtime could not work with my BT848 TV card (error message - "not a video4linux device" and "cannot open capture device /dev/video". The device is there and a simple video app. I wrote myself says:
cyclops: Opened V4L2 device: /dev/v4l/video0
cyclops: VIDIOC_QUERYCAP: error 25, Inappropriate ioctl for device
The TV worked with kernel 2.6.21, although to listen to radio with gqradio I had to start tvtime first to get any sound. I double checked my config but can't see anything missing, I have compiled custom kernels many times and so I could say I am not inexperienced. I am using latest Arch x86-64 on an AMD Athlon 64 machine.
Has anyone else experienced this problem?
My thanks in advance!

Bluetooth issue when working with Safari but not other applications

I have tried two new bluetooth headsets (Motorola 9HD and Sony DR-BT100cx) that both can Pair with and work just fine with the local itunes application and any DVD I use. But these devices do not work with Safari. I tried going to Hulu, YouTube, etc and i can tell the bluetooth device is 'listening' because I can hear it click or wait for a signal. But I never hear anything. If i switch over to DVD or my Podcasts that are local, it works fine. If I go to bluetooth settings and select 'stop using headset' the MacBook speakers pick up right away.
Note: I am a brand new Mac user, so please disregard my OS version I have selected. I have no idea how to find my OS version, nor do I know how to install Firefox to see if it is simply a browser issue.
Thanks,
Jay

I have the same issue. I've tried 3 different btooth headsets, and they all react the same:
- music: ok
- skype: ok
- webcasts / video (safari or firefox): no sound, and video stops
HOWEVER: same system, same headset, using Internet Explorer in my windows xp VM: everything works.
Anyone know how to contact Apple and log this issue?

Why EL doesn't work with custom tags ?!

I don't know why expression lang. doesn't work with me.
here's an example, and please tell me why :
--- the jsp page with EL ==> doesn't work :
<%-- In the name of ALLAH most gacious most merciful --%>
<%@ page language="java" %>
<%@ taglib uri="/cartlib" prefix="cart" %>
<html>
<jsp:useBean id="product" class="ch16.cart.ProductCatalog" scope="application" />
<cart:showCatalog productCatalog="${product}" addToShoppingCartUri="<%= response.encodeURL("AddToShoppingCart.jsp") %>" />
</html>
when using expressions instead, the page works .
the new page is :
<%-- In the name of ALLAH most gacious most merciful --%>
<%@ page language="java" %>
<%@ taglib uri="/cartlib" prefix="cart" %>
<html>
<jsp:useBean id="product" class="ch16.cart.ProductCatalog" scope="application" />
<cart:showCatalog productCatalog="<%= product %>"
addToShoppingCartUri="<%=
response.encodeURL("AddToShoppingCart.jsp") %>" />

Other potential things to check: make sure you are getting the right value passed in
productCatalog="${applicationScope.product}"
${product} by preference would take a pageContext, request or session attribute before the application level one (it uses pageContext.findAttribute).
What do you get if you just print out ${product} on the screen?
It should call a toString() on it for rendering purposes.
