How to set log4j at runtime

Hi,
I am using log4j and want to take the logfile name as a command line argument.
Can anyone help as to how to set the properties which are done statically in log4j.propreties file....
I tried
logProperties.setProperty("log4j.appender.ROOT", "org.apache.log4j.RollingFileAppender");
logProperties.setProperty("log4j.appender.ROOT.File", fileName);
logProperties.setProperty("og4j.appender.ROOT.layout", "org.apache.log4j.PatternLayout");
logProperties.setProperty("log4j.appender.ROOT.layout.ConversionPattern", "%d{ISO8601} - <<<<< [%F][%M] %m >>>>>%n");
but that doesnot seem to work...as the log file itself is not created.
ANyone help is appreciated...

How to set database information runtime with delphi 2007 vcl11

hi
i'm trying to set database information runtime. I'm using mssql express 2005 and doing the following to set database information at runtime.
for x := 1 to crpe1.Tables.Count do
begin
crpe1.LogOnInfo.Items[x].ServerName := server.text;
crpe1.logoninfo.items[x].DatabaseName := database.text;
crpe1.logoninfo.items[x].UserID:=username.text;
crpe1.logoninfo.items[x].Password := pass.text;

HELP: How to set WSDL at runtime (in Flex 4)?

Hi,
My flex application needs to communicate with a Web Service whose location is not known until after deployment; the service's location is known and static during development. This means that my application should be able to communicate with the service whose wsdl url will be different from the "wsdl" value embedded in the Flex-generated code.
I can compute the wsdl url of the deployed service in the application at runtime. However, I am unable to get the application to talk to the service running at the new location.
Specifically, in application_creationCompleteHandler(), I do:
var wsdl:String = hostString+"axis2/myService?wsdl";
myWSvc = new MyWSvc(wsdl);
In the constructor of MyWSvc(), which is the subclass of the auto-generated class for the My Web Service, I do:
public function MyWSvc(runtimeWSDL:String=null) {
     super();
     if (runtimeWSDL != null) {
          wsdl = runtimeWSDL;
          _serviceControl.loadWSDL(wsdl);
          //model_internal::loadWSDLIfNecessary();
This does not work; the auto-generated code always uses the WSDL value embedded in the auto-generated class for the My Web Service.
I would greatly appreciate your expert help in solving or getting around this issue.
Much thanks,

Here is what I did.
I set the settings for each environment in separate settings.xml files in SVN under seperated directories (dev,qa,prod).
Here is the syntax of the settings.xml files. Each will have its respective URLs.
<flex-config>
<compiler>
    <define>
        <name>CONFIG::webServiceURL</name>
        <value>'http://www.xxxxxx.com/webservice_test/echocf7remote.cfc?wsdl'</value>
    </define>
</compiler>
</flex-config>
The deploy.sh script asks for the environment value (dev,qa or prod) among other params, and then passes that in to the Ant like this (note there are extra params for our setup):
ant -v -f build.xml -Dprojectname=${PROJECTNAME} -Dbranchname=${BRANCHNAME} -Dversion=${VERSION} -Denvironment=${ENV} -Dbuilddir=${BUILD_DIR} >> ${LOG_FILE}
These params are used inside the build.xml
After the Ant script checks the code out from SVN in to a staging directory, we load the proper settings.xml from the proper directory based on the user specified environment (in the deploy.sh).
<load-config filename="${staging.conf}/${settings.conf}/${environment}/settings.xml"/>
${staging.conf} is defined in the build.properties and ${environment} is passed in the Ant call in the deploy.sh based on user provided input.
So if the user specifies 'dev' during the deploy.sh execution, then we would load the /build/staging/config/dev/settings.xml
Then in the pre-generates stabs I set the var at the top:
private static const wsdlURL:String = CONFIG::webServiceURL;
and modify the code bellow from hardcoded:
//wsdl = "http://www.xxxxxx.com/webservice_test/echocf7remote.cfc?wsdl";
to using the var:
wsdl = wsdlURL;
The nice thing is that all of the settings.xml 's are stored in the SVN and the correct version is used based on the environment provided by the user input during deployment script execution.
Perhaps there is a more elegant way of doing this but this works and we already use Ant, SVN and a deployment shell script so it fits right in for us.

Receiver SOAP - How to set URL at runtime?

I have configured a Receiver SOAP adapter for sending a cXML message to a vendor in no-soap, keep-headers mode. If I want to extend this to other vendors, I want to set the target URL at runtime. In order to do this, I am able to set the TServerLocation in the Mapping. But in the communication channel, I am not able to select this indicator. I am able to select the 'Use Adapter specific message attributes' and 'Variable Transport Binding' indicators but thats it. I am not displayed any form for selecting the target URL as the field to substitute during runtime. I am using SAP Basis 7.00 for the Adapter Metadata. Does anybody know a work around or patch I need?

Hello James,
I don't know whether this question is still open, but I have faced the same problem now, so here is my solution:
It is right, that the "Target URL" field has to be filled with some "dummy" value to be able to save+activate the communication channel.
In any other communication channels (e.g. like file adapter) you can fill in the <dummy> value. But at the SOAP receiver it doesn't work.
Instead of <dummy>, if you fill in a real URL address, it will always take it instead of the dynamic one.
My solution is, to fill in only the "http://" value, and it will take your dynamic URL from your UDF. (from the variable TServerLocation)
I hope it helps!
Best regards,
Andras

Problem setting up separate runtime environment on OWB 11g

We're trying to set up an environment similar to this: [Split Repositories Implementation|http://download.oracle.com/docs/cd/B28359_01/owb.111/b31280/reqs01.htm#BGBIHAHE]
The server OS is Windows Server 2003 x64 ed, database version is 11.1.0.7
The database/warehouse server was installed with a single database where the default design repository is installed. There is a "control center service" running on the default instance.
We're running OWB clients on separate XP workstations and are able to access the minimal default design repository.
We've set up another database on the same server, this one is to be used for the runtime environment, as described in the references Oracle diagram referenced above.
However we're not able to find much useful documentation on how to set up the second database with the runtime environment and control center service.
Whenever we try to dig deeper into the Oracle documentation, we always end up with hints on how to set up a "remote runtime" on a server without database. This is not what we want to achieve.
A simple step-by-step guide on how to set up a runtime control center repository with audit tables & packages in a database separate from the design repository database is very difficult to find.
Is there anyone who've succeded in doing this that could give us any information on how to implement it?
Regards,
-Haakon-

Thanks again Oleg.
I've now managed to configure up a separate runtime target environment in addition to our design environment.
For others who might struggle with this; here's what I did:
- log on to the Windows server console
- open a command window
- set ORACLE_SID to the newly created runtime target database
- set ORACLE_HOME
to same home as previous OWB default home installation (initial design database)
- run >sqlplus "/as sysdba"
- run %OWB_HOME%/owb/UnifiedRepos/clean_owbsys.sql
to remove all previous OWBSYS setup
- edit %OWB_HOME%/owb/UnifiedRepos/cat_owb.sql
and comment out the 'LOCK USER OWBSYS' statement at the end, then run the script
- run %OWB_HOME%/owb/UnifiedRepos/reset_owbcc_home.sql : this will prompt for "the full path of the Oracle home for the OWB Control Center install:"
. Enter your '<drive>:\Oracle\product\11.1.0\db_1\owb'
- after running reset_owbcc_home.sql one needs to set a known password on the OWBSYS user:
ALTER USER owbsys IDENTIFIED BY password
- finally run the Repository Assistant locally on your server and set up a new repository workspace in the new database. This time (after running the above sql-scripts, the Assistant did not crash halfway through).
We're now able to create a new Control Center from the OWB client installation and deploy tables & mappings and execute mappings on the runtime target system.

How to set a line of table as read only during runtime?

How to set a line (or a cell) of table as read only during runtime?

hi wei
when you create a table keep the readonly property of table as false
you create the columns of table as inputfield.you bind the readonly property of
the inputfield to two context variables
say one for all the columnfields you to want always have as readonly and let this contextattribute of type boolean and let this be attr1
and another for all the columnfields you donot want to be readonly and let this contextattribute of type boolean and let this be attr2
initially set the context attributes attr1 and attr2 as true so the entire table is readonly.
based on the condition you want to check change the attr2 to be false.
if(your condition)
wdcontext.currentcontextelement.setattr2(false);
hope this helps.

CRM 5.2, how to define an assignment set in the runtime depository?

We are using CRM 5.2. I have created a new component and view and the view is exposed as an interface view. Now i have to include this in the overview page of BP_HEAD component. I have enhanced BP_HEAD component and enhanced the view required as well( View Name BPHeadOverview). I have added my new component as the used components in BP_HEAD.
But when i open the enhanced view, i don't see any available assignment blocks. Standard overview page of BP_HEAD had some available assignment blocks but the enhanced one doesn't. Also following message is shown "Define an assignment set in the runtime depository". How can i add my new component and interface view to the available assignment blocks of the overview page of BP_HEAD? Thanks for your help.

Hi Sudipta,
Thanks for your help. I am making good progress.
I believe i am quite close to completion now. Need your help with following questions though -
1) I have a context node BUILACTIVITY. Now i need to only display partial list from this context node? Is there a way i can do this directly with the context node or i have to create a new node and manipulate? If so any tips there?
2) When i create new view it doesn't have graphical representation option any more? Is it that way only? If so can i just create table view and use it?
3) When i create a form view and try to insert a table using <crmic:tableView> tag, i am getting an error messge saying "//BUILACTIVITY/Table" is not a table? What could be the issue?
Thanks a lot for your help again.
Regards

How to set page permission at runtime?

Hi,
I created a portal with several pages in a webcenter portal application.
I have added most of the page in the pagehierarchy and I have set their required security permission.
However, I forgot to add one page in my page hierarchy so what is happening is that the page is not being displayed.
I actually wanted to users with anonymous role to be able to view this page.
Now my question is, is there a way at runtime to set the page security of that page by using any tool such as console or em?
I dont want to redeploy my application since it is already running
I am just not sure how to set the page security at runtime.
Thanks.
Webcenter 11.1.1.6

Documentation for controlling the installation is sadly lacking in detail. This is the best I have seen for the Windows environment:
http://java.com/en/download/help/silent_install.xml
But, there are numerous other PROPERTY variables that are not discussed. Particularly annoying is the addition of yet another JavaUpdate item with the release of 1.5.0_05. If you can get more information, please post a link to it here.

How to set updatable property of view object on runtime

Hello Gurus,
I am new in adf and using jdev 11.1.2.3.
I have two view object which has view link and they are based on entity object. In master view i have a column with the name of status. The target is if the value of status is 'active' then i want to allow add rows in detail view and if it is inactive then wants to disable adding or editing in the detail view.
I don't know how to do this. I don't know how to get the other view object and how to set update able property and where to write code in entity object class or view object class.
Any advice................
Thanks in Advance

There are multiple possible ways to archive this. As the VOs are in a master-detail relationship, you can opt to add a navigation method to the child back to the parent. This method can be accessed via java or groovy to allow the child access to the master row. Once the child has access you can use this to ask the master for it's status and if it's not active disable the edit and update buttons.
If both master and detail are on the same page in the ui, there is an easier way. Drag the status attribute from the master table onto the page as e.g. inputText. This will create a binding for the attribute which changes if you select a row in the master table. As you don't need to inputtext, switch to the source mode of the page and delete it. This will remove the inputtext put keep the binding. Now you can use hte binding in an EL to set the disable property of other components to true like
<af:commandButton text="commandButton 1" id="cb1" disabled="#{bindings.masterstatus.inputValue ne 'active'}"/>
The button will only be active it the binding for masterstatus is active.

HOW TO: Set up your application server to run BC4J

How To set up your application server to run BC4J.
INTRODUCTION
A running BC4J application is actually the combination of:
* Your own application files
* BC4J runtime libraries
In order to successfully run your BC4J application in local mode, the first requirement is
that your application server contains the necessary BC4J libraries.
This How To describes the steps required to ensure that you have a functional
BC4J runtime environment installed on your application server.
Oracle IAS 1.0.2 and Tomcat 3.1 will be used as examples.
THE BC4J RUNTIME LIBRARIES
Whatever application server you deploy to, the following libraries
are required in the following order to be in the classpath.
BC4J Libraries:
xmlparserv2.jar
jdev-rt.zip
jbojdbcpatch.zip
connectionmanager.zip
jbohtml.zip
jboimdomains.zip
ordim817.zip
ordvir817.zip
ordhttp.zip
jbomt.zip
jbodomorcl.zip
jboremote.zip
jndi.jar
jbodatum12.zip
These libraries can be found in <JDEV_HOME>/lib/
INSTALLING THE LIBRARIES ON IAS:
Installing the libraries is simply a matter of copying them to the
application server's filesystem and adding them to the classpath.
IAS's classpath can be modified by editing the file:
<IAS_HOME>\Apache\Jserv\conf\jserv.properties
In this file you'll find the existing pre-installed BC4J libraries which
looks like this:
wrapper.classpath=<IAS_HOME>\Apache\BC4J\lib\ordvir817.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\lib\ordim817.zip
etc.
Note! These BC4J libraries correspond to JDeveloper 3.1.1.
In order to run JDev 3.2 based applications you will have to update these libraries
to JDeveloper 3.2 production.
Steps:
1. Copy (or FTP) the JDev 3.2 BC4J libraries from <JDEV_HOME>\lib to a NEW directory on the
appserver's filesystem called:
<IAS_HOME>\Apache\BC4J\newlib
2. Modify the classpath by editing <IAS_HOME>\Apache\Jserv\conf\jserv.properties.
Example: (modified classpath entries)
# New 3.2 BC4J Runtime libraries
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\xmlparserv2.jar
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jdev-rt.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jbojdbcpatch.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\connectionmanager.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jbohtml.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jboimdomains.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\ordim817.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\ordvir817.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\ordhttp.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jbomt.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jbodomorcl.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jboremote.zip
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jndi.jar
wrapper.classpath=<IAS_HOME>\Apache\BC4J\newlib\jbodatum12.zip
Note: Make sure to remove or comment out the existing 3.1.1 BC4J library entries!
To see the changes, you must restart IAS and that's it, your IAS will be updated with
the JDev 3.2 BC4J libraries which allow you to run BC4J Data Tags among other
things!
INSTALLING THE LIBRARIES ON TOMCAT
As before, this process involves both the copying of the libraries
and modifying the classpath.
After copying the BC4J libraries to a path accessible from Tomcat,
you can modify Tomcat's classpath by editing it's startup script:
<TOMCAT_HOME>\bin\tomcat.bat (NT)
<TOMCAT_HOME>\bin\tomcat.sh (Unix)
Here is a portion of a modified tomcat.bat (on NT)
rem Add BC4J libraries
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\xmlparserv2.jar
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jdev-rt.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jbojdbcpatch.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\connectionmanager.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jbohtml.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jboimdomains.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\or dim817.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\ordvir817.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\ordhttp.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jbomt.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jbodomorcl.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jboremote.zip
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jndi.jar
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\jbodatum12.zip
rem Add Oracle JDBC library
set CLASSPATH=%CLASSPATH%;D:\bc4j_lib\classes12.zip
Note: I also added the Oracle JDBC library since Tomcat does not have it.
It is found at:
<JDEV_HOME>\jdbc\lib\oracle8.1.7\classes12.zip
And That's It!
When Tomcat is restarted using this script, the necessary BC4J libraries
will be in the classpath..
A follow up How To:"How To Deploy a BC4J JSP Application on IAS and Tomcat"
will be posted shortly!

How to set time zone for a session in Client Only installation

Environment:
OS : Unix (HP-UX 11.0)
Oracle DB : Ver 8.0.5
Developer : Ver 1.6 ( Client only Installation)
Developer also on Unix.
RDBMS and Developer Installed on different
home directories.
Our development is Forms 4.5 on X windows.
Runtime is forms character mode.
Probelm Description:
To run the application I am using TWO_TASK to connect to the database. In our application we have to take care of time zones. For that in previous versions(NO TWO_TASK used) I used TZ unix environment variable, to get time zone dependent time wherever sysdate is used.
Now because I am using TWO_TASK, oracle is no more using users TZ settings.
Question : Is there any way I can make oracle to use the TZ environment setting

Thanks for replying Johnny!
What you are referring to is adding a city. I need to know how to set the time zone in settings -> Date & Time -> Timezone. Unless & untill this is set properly the iPod will never show me the right time. Please help me with it.
I will definately use your advice on the second query.
Thanks once again!
