Application to Read and Write the Configuration Data from a xml file

Hi,
I have to develop a Webdynpro application that will do the following:
Read the Configuration data from an xml file
If stored in a file , and the file is not found, prompt the user to provide the file location.
Pre-Populate the screen(table) with the configuration data
Allow the user to edit the data
Store the configuration data when the user hits the Save button
The config xml file details are as follows:
Regardless of the location of the configuration data, the following fields will be stored
Application (string) will always contain u201CSFA_EDOCSu201D
Key (string) eg LDAP_USER, DB_PREFIX, etc.
Type (character) u201CPu201D = Plain Text, u201CEu201D = Encrypted
Value (string)
Since I am new to WD, I would require help on this.
Please help.Its Urgent.
Regards,
Vaishali.

Best Practices for Accessing the Configuration data Modelled as XML File in

Hi,
I refer the couple of blof posts/Forum threads on How to model and access the Configuration data as XML inside OSB.
One of the easiest and way is to
Re: OSB: What is best practice for reading configuration information
Another could be
Uploading XML data as .xq file (Creating .xq file copy paste all the Configuration as XML )
I need expert answers for following.
1] I have .xsd file which is representing the Configuration data. Structure of XSD is
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue</Config>
<FrameworkConfig>
2] As my project will move from one env to another the property-value will change according to the Environment...
For Dev:
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Dev</Config>
<FrameworkConfig>
For Stage :
<FrameworkConfig>
<Config type="common" key="someKey">proprtyvalue_Stage</Config>
<FrameworkConfig>
3] Let say I create the following Folder structure to store the Configuration file specific for dev/stage/prod instance
OSB Project Folder
|
|---Dev
|
|--Dev_Config_file.xml
|
|---Stage
|
|--Stahe_Config_file.xml
|
|---Prod
|
|-Prod_Config_file.xml
4] I need a way to load these property file as xml element/variable inside OSb message flow.?? I can't use XPath function fn:doc("URL") coz I don't know exact path of XMl on deployed server.
5] Also I need to lookup/model the value which will specify the current server type(Dev/Stage/prod) on which OSB MF is running. Let say any construct which will act as a Global configuration and can be acccessible inside the OSb message flow. If I get the vaalue for the Global variable as Dev means I will load the xml config file under the Dev Directory @runtime containing key value pair for Dev environment.
6] This Re: OSB: What is best practice for reading configuration information
suggest the designing of the web application which will serve the xml file over the http protocol and getting the contents into variable (which in turn can be used in OSB message flow). Can we address this problem without creating the extra Project and adding the Dependencies? I read configuration file approach too..but the sample configuration file doesn't show entry of .xml file as resources
Hope I am clear...I really appreciate your comments and suggestion..

If you can enforce some sort of naming convention for the transport endpoint for this proxy service across the environments, where the environment name is part of the endpoint you may able to retrieve it from $inbound in the message pipeline.
eg. http://osb_host/service/prod/service1 ==> Prod and http://osb_host/service/prod/service2 ==> stage , then i think $inbound/ctx:transport/ctx:uri can give you /service/prod/service1 or /service/stage/service1 and applying appropriate xpath functions you will be able to extract the environment name.
Chk this link for details on $inbound/ctx:transport : http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1080822

How to read configuration data from an xml file (not web.xml)?

Hi,
I want to separate the application specific configuration parameters in a separate xml file and read them as and when they are needed? I know that I can use the wb.xml but I want to separate them in a different xml file because I don't want the web.xml file to be played around later after deployment. If any change is needed then it should be done in the application-config.xml.
How can I read the parameters from this xml file in my jsp code and also what should be the location of this file if I have
../webapps/Root/application
directoty structure ?
Any help is greatly appreciated.

can you give an example of a property file and also
it is loaded in the jsp ?Hmm... loading properties in a JSP is not a very good idea. You should do it in a separate class, rather than mixing the logic with the display logic.
Properties properties = new Properties();
properties.load(UtilClass.class.getResourceAsStream("config.properties"));
// Add a try - catch block around the load
// for IOException...

HELP!: How to read and write to External hard drives? What file system to use?

hey all, this has been really frustrating for me today. i want to be able to write to an external HDD that's formatted in NTFS. today i find out it isn't possible to write to this file system on a Mac and that on FAT32 it is possible. however, FAT32 can't address files larger than 4GB so this hurts me a lot. are there any other file systems that'll allow me to read and write from a Mac? my goal was to use freeNAS to build a NAS with an old tower and connect my external hard drives to it, but if i can't write to them this may not be possible.
thanks guys, i'd appreciate any help!

Getting data from an XML file and pushing it to a database

I need to create a coldfusion page that grabs an incoming xml file, extract the data and then push it into a database. I have never done anything like this, and have been reading as much as I can find. Can anyone recomend a good resource or give me a hand on how I go about doing this?
The xml file is coming from another page. Basically the source page is a simple text box that an xml file is pasted into and submited. The action page must grab the xml file, pull out the data and funnel it into a table. Then it must query the table and based on the results of the query, push a new xml file back to the user.
<my brain is already hurting>

I'd start by looking at the CF documentation related to XML and Ben Forta's books.
"About XML and ColdFusion" from CF docs:
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec133ba -8000.html
Ben Forta's books
http://www.forta.com/books/0321679199/
It would be good to know:
1. What the workflow is for your task. Can you describe your task in detail and provide samples of the XML and database?
2. The database you are using and the structure of your tables.
3. The version of CF you are using.

How to store ,retreive and edit data from an xml file

I am new to XML. I am creating a phone book in JSP with backend as an XML file.How can I store retrieve and edit datas from a jsp file.
Please provide me with examples.I dont want to use bean.
Please provide examples

You will have to do some leg-work yourself. You will probably want to use DOM to parse and manipulate your XML data. Xerces (xml.apache.org) is a good open source parser. There are extensive examples on their site.

Using HTTPService to import data from a XML file

Hello there!
I'm having some problem's with this import... If anyone can
help, I would appreciate it!
I'm using this type of information as data source:
public var dataCollection:ArrayCollection =
new ArrayCollection([
{ id: "P1", name: "Porto", type: "team", children: [
{ id: "R1", name: "Dr Silva", location: "Bloco 1", type:
"member" },
{ id: "R2", name: "Dra Neto", location: "Gabinete", type:
"member"
{ id: "P2", name: "Braga", type: "team", children: [
{ id: "R3", name: "Dr Santos", location: "Bloco 2", type:
"member" },
{ id: "R4", name: "Dra Sonia", location: "Piso 1", type:
"member"
But I want to import it from a XML file like this:
<?xml version="1.0" encoding="utf-8"?>
<items>
<item id="P1" name="Porto" type="team">
<children id="R1" name="Dr Silva" location="Bloco 1"
type="member" />
<children id="R2" name="Dra Neto" location="Gabinete"
type="member" />
</item>
<item id="P2" name="Braga" type="team">
<children id="R3" name="Dr Santos" location="Bloco 2"
type="member" />
<children id="R4" name="Dra Sonia" location="Piso 1"
type="member" />
</item>
</items>
I already import the file, but can not translate the data
into a array collection.
private function initApp():void {
var httpService:HTTPService = new HTTPService();
httpService.url = "dataprovider.xml";
httpService.resultFormat = "e4x";
httpService.addEventListener(FaultEvent.FAULT,
onFaultHttpService);
httpService.addEventListener(ResultEvent.RESULT,
onResultHttpService);
httpService.send();
private function onFaultHttpService(e:FaultEvent):void
Alert.show("Error reading data file.");
private function onResultHttpService(e:ResultEvent):void
//Convert the xml data to a array collection
Thank you

Hello Peter, and thank you for your reply's.
My problem is that I'm receiving the data from the external
file and I don't know how to get the children in place... I mean, I
also have some data being received form a file that I can convert
into an array collection, but the thing is, that file doesn't have
children structure...
It's something like this:
<?xml version="1.0" encoding="utf-8"?>
<items>
<item id="T1" resourceId="R1" name="Cardiologia"
startTime="25-3-09 8:0:0" endTime="25-3-09 8:30:0" />
<item id="T2" resourceId="R2" name="Raio-X"
startTime="25-3-09 9:0:0" endTime="25-3-09 9:15:0" />
<item id="T3" resourceId="R3" name="Analises"
startTime="25-3-09 12:0:0" endTime="25-3-09 12:45:0" />
<item id="T4" resourceId="R4" name="Consulta"
startTime="26-3-09 8:0:0" endTime="26-3-09 9:0:0" />
</items>
And I solve it with this (don't know if is the best):
private function onResultHttpServiceTask(e:ResultEvent):void
var a:Array = xmlListToObjectArray(e.result.item);
tasks = new ArrayCollection(a);
protected function
xmlListToObjectArray(xmlList:XMLList):Array
var a:Array = new Array();
for each(var xml:XML in xmlList)
var attributes:XMLList = xml.attributes();
var o:Object = new Object();
for each (var attribute:XML in attributes)
var nodeName:String = attribute.name().toString();
var value:*;
value = attribute.toString();
o[nodeName] = value;
a.push(new ObjectProxy(o));
return a;
But when the children "enter in action" I don't know how to
bring them to the array...
This code you send it's preaty much the thing I need, but the
thing is that I don't know how to call the children with data as
e:ResultEvent...
If you can help a bit more, I would really appreciate...
Thank You

Airport can no longer read or write the configuration of Time Capsule

I have a MacBook Pro running OSX 10.8.3 and maintained with all available patches. I have also a Time Capsule with version 7.6.3 of the firmware. I use AirPort 6.2. So everything seems to be updated with the latest versions.
This has really been a good setup for nearly a year now, but earlier this month Time Machine suddenly stopped to work and could no longer do backups to the Time Capsule. I have tried to factory reset the Time Capsule several times, but I still get problems when writing the configuration to the Time Capsule. I get an error message saying "An error occurred while updating the configuration".
Airport is furthermore not able to detect the Time Capsule correctly anymore, so I have to configure it by entering the IP address. But after setting up WLAN, disks, etc. and enhanching the security, I just receive the error message when I try to write the config. The Internet connection works perfectly anyway, both via cable and wireless.
Anyone got any tips?

Do the setup by ethernet in full isolation from the network.
Start from a full factory reset.
I would recommend you take the firmware back to 7.6.1 or even earlier if the TC is older than 12months. 7.5.2 was very reliable. All these bugs started with 7.6 and the change to Lion.
I would also recommend installing 5.6 utility.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 (now 6.2 if you updated) so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
For screen shots see this post.

Reading data from a XML file.

Hi,
I am new user to webdynpro and has the task of reading data from XML file.The file is created using XML form Builder and is stored at a location.But my code gives me the path instead of the content in the data.
The code is :
try
      IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
       com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
// create an ep5 user from the retrieved user
       IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
       IResourceContext context = new ResourceContext(ep5User);
/Specify the path of ur document here./
       RID pathRID = RID.getRID("/documents/70f51182-84c3-2710-ce91-8d5fbfde713d.xml");
       //RID pathRID = RID.getRID("/documents/hol.txt");
       wdContext.currentContextElement().setSetDisp(pathRID.toString());
       IResource resource = ResourceFactory.getInstance().getResource(pathRID, context);
       InputStream in = resource.getContent().getInputStream();
       ByteArrayOutputStream out = new ByteArrayOutputStream();
       byte[] buffer = new byte[4096];
       int bytesread = 0;
       while ((bytesread = in.read(buffer)) != -1)
           out.write(buffer, 0, bytesread);
       String myData = out.toString();
/*myFile will containS the content of the document./
       wdContext.currentContextElement().setSetDisp(myData);
       catch (Exception e)
        // wdContext.currentContextElement().setTextdisp("IO Error:" + e.getMessage());
text data is read from the location but XML data is not read.
Please help me out.

hi SriRam,
For some reasons you are not able to change the value of attribute SetDisp ahich you gave the default value as the path using the following statement
wdContext.currentContextElement().setSetDisp(myData);
Remove that line.First try to open the files using creating new window instance
IWDWindow window =
            wdComponentAPI.getWindowManager().createExternalWindow(
                  "http://<server name>:<port no>/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs"
                        + "/documents/Public Documents/...."
                        + "/"
                        +<name>,
                  "from km repository",
                  false);
      window.open();
Then we can be sure that the error is due to reading data using input stream

Is it possible to view/get the table data from a dump file

I have dmp files generated using expdp on oracle 11g..
expdp_schemas_18MAY2013_1.dmp
expdp_schemas_18MAY2013_2.dmp
expdp_schemas_18MAY2013_3.dmp
Can I use a parameter file given below to get the table data in to the sql file or impdp the only option to load the table data in to database.
vi test1.par
USERID="/ as sysdba"
DIRECTORY=DATA
dumpfile=expdp_schemas_18MAY2013%S.dmp
SCHEMAS=USER1,USER2
LOGFILE=user_dump_data.log
SQLFILE=user_dump_data.sql
and impdp parfile=test1.par.

Hi,
To explain more about my situation.
Target database has the dump files, where as the source database (cloud) doesn't have access to the target database.
However, I can request the target DB DBA team to run the par files and provide me the output like a SQL file which I can take and run it in my source database.
I got the metadata the same way, but is there any way I could get the data from the dump files on the target DB without actually accessing it? My question might sound weird, but please let me know.
<
1. export from the source into a dumpfile. You can do this on the source database and then copy the file over to your local database or you can do this from a local database if you have a database link defined on the local database that points to the source database. In the second case, your dumpfile will be created on your local database.

How can i access the dump using the database link?

Is there some more information about this topic?
thanks in advanced.

Hello Shi,
Could you please provide details about how did you solve this problem?

Error loading data from an XML file using HTTPService

Hello All,
I have a runtime error that has got me beat at the moment I am building an App in Flash Builder 4 to run on AIR.
The error is as follows: TypeError: Error #1009: Cannot access a property or method of a null object reference.
What i'm Trying to Do:
I have 2 DropDownList controls, the first is populated with country names and the other with language options. All the 1st DropDownList control does
is set an image control to display the country flag and enable the 2nd DropDownList.
The 2nd DropDownList sets the langCode variable equal to the chosen language code. I then call the language function and pass it langCode. Using this variable, I build up the string
so that langFilePath will be equal to the XML file (which is "Lang_GBR.xml") location on my desktop and then call the HTTPService.
As soon as the language function is called, the runtime error occurs and highlights the line with btn_LS_mainMenu.label = loadLangService.lastResult.Lang.GlobalTags.btnMenu;
where I try to assign the button label with a new value from the XML file.
I suspect this may be a trivial error but I just can't see it at the moment.
Any help or guidance would be appreciated. Thanks
Code:
<fx:Script>
        <![CDATA[

Don't sure about your XML structure, but for now i see the problem here between this 2 lines of code:
loadLangService.send();
btn_LS_mainMenu.label = loadLangService.lastResult.Lang.GlobalTags.btnMenu;
Think data that your httpService should receive just can't go so fast to populate the lastResult before you call it in the next line
Try adding a result listener to your service before you send it:
loadLangService.addEventListener(ResultEvent.RESULT, handler);
loadLangService.send();
function handler(event:ResultEvent):void {
     btn_LS_mainMenu.label = loadLangService.lastResult.Lang.GlobalTags.btnMenu;
