MWA Setup This article will explain to you
Configuration Files
Start/stopping Listener Start: Stop :
Directory Structure in R11 Directory structure in R12 MWA GUI Client Setup In order to simulate the Mobile Device on your PC, you have to do the following setup: Step 1: Step 2: %JAVA_TOP%\bin\java -classpath %JAVA_TOP%\lib\classes.zip;%MWA_GUI_TOP%\lib\j4205328.zip oracle.apps.mwa.awt.client.StartGUI Step 4:
Development and Deployment: The development of Mobile Applications can be done using any IDE like JDeveloper, Eclipse etc. After that in order to
In order to test it, we should have our own function in AOL. This function should refer to the Function Java Class (eg) xxx.custom.server.CustomTestFunction
After doing so, we have to attach this function to submenu and then to the Mobile Navigation Menu
After doing so, your menu entry will come into your mobile application and you can test your new pages
MWA Error Logging and Debugging: When you develop and test mobile applications, you may need to write some logging information which will be useful in debugging. The different Log level from highest to lowest is as follows:
oracle.apps.inv.utilities.server.UtilFns
UtilFns.trace("#########Trace Level Logs#########");
There are lot of other utility APIs available in this helper class (UtilFns.java) which can be used for various other aspects.
Example code snippet for error logging: public void fieldEntered(MWAEvent mwaevent){ UtilFns.trace("Inside Field Entered"); ses = mwaevent.getSession(); String s = UtilFns.fieldEnterSource(ses); // Prints the Current Bean's ID UtilFns.trace("CustomFListener:fieldEntered:fldName = " + s); }
In the above snippet, we print a message “Inside Field Entered” when the user enters any field in the Mobile Application Also, we print the name of the field using the line UtilFns.trace("CustomFListener:fieldEntered:fldName = " + s); Please note that, the above log messages can be found only when the log level is set to “trace” in mwa.cfg file.
Where to look for log information? The log files are located under $INST_TOP/logs (in R12).
All the log files start with Telnet_port_no as a prefix.
Example log files for port no 10240: [appldev@w-oraap01 logs]$ pwd /u01/appldev/DEV/inst/apps/DEV_w-oraap01/logs [appldev@w-oraap01 logs]$ ls -al 10240* -rw-r--r-- 1 appldev dba 255626 Feb 8 13:28 10240.INV.log -rw-r--r-- 1 appldev dba 83 Feb 8 13:26 10240.sta -rw-r--r-- 1 appldev dba 154063 Feb 8 13:50 10240.system.log -rw-r--r-- 1 appldev dba 3296 Feb 4 11:11 10240.WMS.log [appldev@w-oraap01 logs]$
All the system level log like page names, parameter passed to PLSQL APIs, LOVs etc can be found under <port_no>.system.log
Easiest way to look at log files: Since the volume of information written in the log file is huge, it is tough to go through the entire file. A simpler way which I used to find the log information is to run the command tail -f 10240.INV.log By doing so, you can see the updated log information as and when you click on the fields on mobile application.

FileLogger.getSystemLogger().trace can also be used for tracing purpose....What is the basic difference between Utilfns.trace and FileLogger.getSystemLogger().trace. Pls explain...
Hi Anil
I am a recruiter I am very much interested in Oracle Apps HRMS FUnctional Module I did apps learning course from a private institute for Core HR and iRecruitment and OLM I could get a relative idea on these modules. But when comming to realtime scenario I am feeling it very different I want to be frank that I am planning to start entering into a consultant level as a fresher but I dont have those opportunities Atleast make me thorrow in Oracle Apps with any of the modules Focusing COre HR and Payroll with real time examples I have gone through your site and i appreciate that you share your knowledge with others too And that made me dare to ask your help as I need it please keep me updated posted to my email id for the first time atleast with a positive response I will keep in touch Thanks Raghav
RE: What is date tracking, how it is used in HRMS ?
-------------------------------------------------------------------------------- Hi, Well date tracking isa feature in Oracle HRMS esp with all tables whose name send with _F eg:per_all_people_f .Now what happens here is we cannont purge a record what we can do is endate a record and if we need to create an extension eg: of an assignment then we end-date the assignment and on a new record that is appended to the table we create a new record with starting date after the eend date and can restate the assignment, used in cases of Re-hire after end of assignment or in the extension of assignment beyond the end date. It helps Oracle maintain historical data and hence the tables are data trackable
Hi mmitraa,
Thanks a lot for bringing this up. oracle.apps.inv.utilities.server.UtilFns is a helper class which acts as a helper class for Mobile Application Utility APIs. It has Java wrappers for most of the common functionalities like LPN Generation, getting Lot Qty etc. What I mean here is has lot of other APIs apart from Error Logging On the other hand, java.lang.Object | --java.io.Writer | --java.io.PrintWriter | --oracle.apps.mwa.container.Logger | --oracle.apps.mwa.container.FileLogger FileLogger is dedicated Class for Error Logging. Am not sure about the place it writes the log messages.It would be great if you provide some information about this.This would definitely give an better idea between the two types of logging. Thanks and Regards, Senthil Basically i don't have much knowledge what UtilFns does. Can you publish any doc related to this ? if you have any doc pls fwd it to me on my email id mmitraa@gmail.com Where as FileLogger is concerned it will log the error messaged into port.system.log file. you can user methods like .trace/ .error etc
UtilFns writes log information on port.INV.log
I am in process of writing a documentation for this. I will publish this in near future. Thanks and Regards, Senthil
is there any other option needs to be setup other than setting log option to trace.....in mwa.cfg file. ???????
because i used UtilFns toooo but never seen it logging anything in INV.log file....
Have u restarted your telnet listener after editing the mwa.cfg file?
yes.....is there any other option that i need to set ? i'm in 11.5.10
another thing i wanted to know ....what are the possible values and meaning for MWA: Debug Level ?
No other setup is required. BTW, how about your port.system.log? Are you getting entries into that file?
Can you paste the various variables and their values in mwa.cfg file? Regarding the profile options MWA: Debug Trace and MWA: Debug Level, I havent used them. May be they are reserved for future. If I get any useful info, I will update you. ![]() written by jabastion , March 14, 2008
