Can I use addAuditTrailEntry(String message, Object detail) in a jar file?
I have a lot of jar libraries that I need to import into my BPEL process. It's not practical for me to copy all the code flatly into an embedded java / bpelx.
How can I call the addAuditTrailEntry method inside the classes in my jar file?
e.g.
I import libraries.jar at the top of my .bpel file.
In my embedded java I do:
MyClass myclass = new MyClass();
myclass.doSomething();
In the public void doSomething() method I would like to write to the audit trail directly. Currently I am simply having the doSomething() method return a String with a summary of everything it has done. This is not good enough because the method takes a long time to complete and I need a running audit trail so that I can take actions depending on what is going on in it.
I can't seem to find the documentation... I assume in my MyClass.class I will need to import some bpel jars so that it can comprehend what a bpel process is... then pass the current process instance into the MyClass file so that it can call its addAuditTrailEntry method... is this right?
I envision something like:
import orabpeljars.jar
public MyClass(BPELProcess process)
process.addAuditTrailEntry("In MyClass Constructor");

Can I create a SOAP message object from a string?
can i create a soap message object in saaj with a string containing soap xml?
I know messageFactory has a constructor that
public abstract SOAPMessage createMessage(MimeHeaders headers, InputStream in)
does anyone know how to use this? Specifically transform a SOAP message in string format to something i could pass this constructor.
Is there a better way to do this?
I'm not EVER going to use apache's tomcat or GLUE or anyting and need to send a soap message from a client to a server via SOAP. I need to be able to transfer a String SOAP document to something i can search for elements with.sorry for being critical but the tutorial you just linked to is for the most part USELESS. it doesnt deal with Java just what a SOAP message looks like. yeah, i get it, its like xml. now how do i do what i want to with saaj?
something like
String sm;
sm = in.readLine(); //gives me a whole SOAP document (pretend)
sm--->>>MAGIC------>>>>>MIMEHeaders headers & InputStream sm_in
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage(headers, sm_in);
SOAPBody soapBody = message.getSOAPBody();
Name bodyName = factory.createName("YUP","m","http://theinternet/YUP");
Iterator iterator = soapBody.getChildElements(bodyName);
SOAPBodyElement bodyElement = (SOAPBodyElement)iterator.next();
String yup = bodyElement.getValue();
System.out.println("YUP element of the SOAP document is " + yup);what is the MAGIC in the above code? -

Q: Can you use xm:multiple with Objects other than Strings?
<br>
A: You bet. Attached find a text file with some code from the example I showed
today, a version of the multipleSayHiTo() method that has a parameter of an Array
of Person objects rather than a parameter of an Array of Strings. The code within
the text file comes from the Greeting.jws file (the Greeting Web Service).
[multiple.txt]So you are saying that the recovery discs I made do include the copy of windows that was originally installed?
Absolutely! They will restore the hard disk to its original out-of-the-box contents. Follow the instructions in the section Restoring from recovery DVDs/media, which begins on p. 73 of the User's Guide.
Satellite A660 Series User’s Guide
maybe i can make a deal with wd to have them swap this drive out for the BEKT instead...
That would be a good idea in any case.
As I said, the 10-fc12-045d error would not be due to the drive's being AFT, but more likely the discs are not being read properly. New discs can be obtained from Toshiba. Scroll down to Get Recovery Media here

How can I use "Family Sharing" without giving details of my credit or debit card? I do not want to give my cards data, I have always used iTunes prepaid cards.
Hi Saramos,
When setting up Family Sharing you must have a credit or debit card as your payment method. See this article for reference -
Family purchases and payments
When a family member makes a purchase it will be billed to any gift or store credit that they have first. If none exists it will be billed to you.
As the family organizer, you may not set your billing method for purchases to anything other than a credit or debit card. If you have a store credit such as from pre-paid cards, it may not be shared with other family members. See this article for reference -

Can I use to.String() method with NamedCache
Hi,
I have a distributed cache. Can I use to.String() method to print the contents of cache on the console. In my case it is not working..Do I neet to import anything?
NamedCache cache = CacheFactory.getCache("Test");
cache.put("hello", "world");
System.out.println(cache.toString());
Thanks,
ChayaHi Chaya,
Assuming that I understand your question correctly, each JVM has the same view of the cache if you're using a distributed (or optimistic, replicated, ...) cache. So when you add records from one JVM, they are visible to all the JVMs immediately (if you start up a new JVM, it will join the cluster and share the data as well).
So if you populate a named cache from JVM1, you can simply execute the display code (from my previously reply) in any JVM connected through Coherence, and it will display the entire contents of the logical named cache.

Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ?
Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ? Please help me as its urgent.THanks for your help in advance.
Hi Jay,
SSIS can only recognize the absolute path of a XML Configuration file, the relative path is not supported. Furthermore, if the XML Configuration file is already generated, we can use the Environment variable package configuration type instead so that
SSIS runtime automatically looks for the configuration file from the path defined in the environment variable. This is convenient when we need to deploy a package to different environment. We only need to define the environment variable for package configurations
once on each server, and then the variable can be used by all the packages on this server.

How can I use Automator to extract specific Data from a text file?
I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:
Link Time =
DD/MMM/YYYY
Random
Text
161 179
bytes of CODE memory (+ 68 range fill )
16 789
bytes of DATA memory (+ 59 absolute )
1 875
bytes of XDATA memory (+ 1 855 absolute )
90 783
bytes of FARCODE memory
What I would like to have as a final file:
EXCEL COLUMN1
Column 2
Column3
Column4
Column5
Column6
MM/DD/YYYY
filename1
161179
16789
1875

You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);

How can i use a string name as an onject name.please help!
hi it seems like an easy one but i can not find it anywhere.how can i use the name of a string as a name of an object such as the code(my problem is the code)...
public void oda(String name1){
String name2=name1+"s";
String name3=name1+"ss";
TextArea name1=new TextArea();
TextArea name2=new TextArea();
TextArea name3=new TextArea();
i think my problem is clear but to be sure..
how can i give a name to an object in my textarea which is already using as a string.
thank u .it get very compilcated to change the name of the object you created. identity is something you don't want to mess with..you can do it by usin reflection, but it will slow down your application and (again) is quite complicated...
a simple solution (and more object-oriennted) is to create a Wrapper, Decorator, or Extends the class.
example
public class MyTextBox{
private String name = null;
private boolean value = false;
private JTextArea txtArea = null;
public MyTextBox(String name, boolean value){
txtArea = new JTextArea();
this.value = value;
this.isOn = isOn;
public String getComponentName(){ return name; }
pubic boolean getComponentValue(){ return value; }
public JTextArea getTextArea(){ return area; }

Billing_RateKrist,
If I understand you correctly you want to have a number of View Object attributes in a page to be accessible through 'subtabs', and want the correct subtab to be shown when the 'discriminator' field is changed. I am sorry for the confusion, I got thrown off track with all the super-subtype Entity details, but in the UI you are only dealing with ViewObject (usages), and not Entity Objects.
Anyway, we can not generate 'subtabs'. There is a feature on our 'Enhancement list' to make the Regions have a 'stacked' property, which I think would come pretty close to what you need: you could group ViewObject Atributes together in Regions, and 'stacked' Regions would be generated as tab pages. We have not implemented this feature yet, and even if we had, you would have to change it post-gen because in your case, you would not want the end user to be able to 'switch tabs', but only a change of the 'discrimitator' field should do that.
We have shipped some templates, though, for creating subtabs for child groups. Perhaps you could take a look if some of that code could be useable for your.
I would suggest the following approach:
1.) In the application structure file, create 'Regions' for all subtypes, and in the BC4J Property Editor, assign the 'subtype' attributes to the corresponding Region.
2.) Regenerate the page. Now you should have a separate 'header' element for each subtype, containing the appropriate attributes.
3.) Now you will need to transform those 'headers' to 'subtype tabs'. You could do that by borrowing code from our 'tabbed child' templates, or, alternatively, you could use a similar, Javascript-based technique that we use for switching between Quick Search and Advanced Search.
4.) Finally, you should device a mechanism to change the active tab when changing the 'discriminator' column in the area above the tabs, with the supertype fields.
Hope this helps,
