Initialization Blocks -- Practical Example.

I am curious about I topic that I have just recently learned about and would like to post it for discussion.
Does anyone know of a practical example of the use of an initialization block? Why would one want to use an initialization block? What can be accomplished with an initialization block that you cannot accomplish with a constructor that doesn't accept any parameters?

Hi Robert,
Initializers are used in initialization of object and classes. They can also be used to define constants in Interfaces.
Here I am explaning by corelating the Constructor with Initialization.
In what order is initialization code executed? What should I put where ?
Instance variable initialization code can go in three places within a class:
In an instance variable initializer for a class (or a superclass).
class C {
String var = "val";
In a constructor for a class (or a superclass).
public C() { var = "val"; }
In an object initializer block. This is new in Java 1.1; its just like a static initializer block but without the keyword static.
{ var = "val"; }
The order of evaluation (ignoring out of memory problems) when you say new C() is:
1.Call a constructor for C's superclass (unless C is Object, in which case it has no superclass). It will always be the no-argument constructor, unless the programmer explicitly coded super(...) as
the very first statement of the constructor.
2.Once the super constructor has returned, execute any instance variable initializers and object initializer blocks in textual (left-to-right) order. Don't be confused by the fact that javadoc and
javap use alphabetical ordering; that's not important here.
3.Now execute the remainder of the body for the constructor. This can set instance variables or do anything else.
In general, you have a lot of freedom to choose any of these three forms. My recommendation is to use instance variable initailizers in cases where there is a variable that takes the same value
regardless of which constructor is used. Use object initializer blocks only when initialization is complex (e.g. it requires a loop) and you don't want to repeat it in multiple constructors. Use a constructor
for the rest.
Here's another example:
Program:
class A {
String a1 = ABC.echo(" 1: a1");
String a2 = ABC.echo(" 2: a2");
public A() {ABC.echo(" 3: A()");}
class B extends A {
String b1 = ABC.echo(" 4: b1");
String b2;
public B() {
ABC.echo(" 5: B()");
b1 = ABC.echo(" 6: b1 reset");
a2 = ABC.echo(" 7: a2 reset");
class C extends B {
String c1;
{ c1 = ABC.echo(" 8: c1"); }
String c2;
String c3 = ABC.echo(" 9: c3");
public C() {
ABC.echo("10: C()");
c2 = ABC.echo("11: c2");
b2 = ABC.echo("12: b2");
public class ABC {
static String echo(String arg) {
System.out.println(arg);
return arg;
public static void main(String[] args) {
new C();
Output:
1: a1
2: a2
3: A()
4: b1
5: B()
6: b1 reset
7: a2 reset
8: c1
9: c3
10: C()
11: c2
12: b2
When should I use constructors, and when should I use other methods?
The glib answer is to use constructors when you want a new object; that's what the keyword new is for. The infrequent answer is that constructors are often over-used, both in when they are called and
in how much they have to do. Here are some points to consider
Modifiers: As we saw in the previous question, one can go overboard in providing too many constructors. It is usually better to minimize the number of constructors, and then provide modifier
methods, that do the rest of the initialization. If the modifiers return this, then you can create a useful object in one expression; if not, you will need to use a series of statements. Modifiers are
good because often the changes you want to make during construction are also changes you will want to make later, so why duplicate code between constructors and methods.
Factories: Often you want to create something that is an instance of some class or interface, but you either don't care exactly which subclass to create, or you want to defer that decision to
runtime. For example, if you are writing a calculator applet, you might wish that you could call new Number(string), and have this return a Double if string is in floating point format, or a Long if
string is in integer format. But you can't do that for two reasons: Number is an abstract class, so you can't invoke its constructor directly, and any call to a constructor must return a new instance
of that class directly, not of a subclass. A method which returns objects like a constructor but that has more freedom in how the object is made (and what type it is) is called a factory. Java has no
built-in support or conventions for factories, but you will want to invent conventions for using them in your code.
Caching and Recycling: A constructor must create a new object. But creating a new object is a fairly expensive operation. Just as in the real world, you can avoid costly garbage collection by
recycling. For example, new Boolean(x) creates a new Boolean, but you should almost always use instead (x ? Boolean.TRUE : Boolean.FALSE), which recycles an existing value rather than
wastefully creating a new one. Java would have been better off if it advertised a method that did just this, rather than advertising the constructor. Boolean is just one example; you should also
consider recycling of other immutable classes, including Character, Integer, and perhaps many of your own classes. Below is an example of a recycling factory for Numbers. If I had my choice, I
would call this Number.make, but of course I can't add methods to the Number class, so it will have to go somewhere else.
public Number numberFactory(String str) throws NumberFormatException {
try {
long l = Long.parseLong(str);
if (l >= 0 && l < cachedLongs.length) {
int i = (int)l;
if (cachedLongs[i] != null) return cachedLongs;
else return cachedLongs[i] = new Long(str);
} else {
return new Long(l);
} catch (NumberFormatException e) {
double d = Double.parseDouble(str);
return d == 0.0 ? ZERO : d == 1.0 ? ONE : new Double(d);
private Long[] cachedLongs = new Long[100];
private Double ZERO = new Double(0.0);
private Double ONE = new Double(1.0);
We see that new is a useful convention, but that factories and recycling are also useful. Java chose to support only new because it is the simplest possibility, and the Java philosophy is to keep the
language itself as simple as possible. But that doesn't mean your class libraries need to stick to the lowest denominator. (And it shouldn't have meant that the built-in libraries stuck to it, but alas, they
did.)
I have a class with six instance variables, each of which could be initialized or not. Should I write 64 constructors?
Of course you don't need (26) constructors. Let's say you have a class C defined as follows:
public class C { int a,b,c,d,e,f; }
Here are some things you can do for constructors:
1.Guess at what combinations of variables will likely be wanted, and provide constructors for those combinations. Pro: That's how it's usually done. Con: Difficult to guess correctly; lots of
redundant code to write.
2.Define setters that can be cascaded because they return this. That is, define a setter for each instance variable, then use them after a call to the default constructor:
public C setA(int val) { a = val; return this; }
new C().setA(1).setC(3).setE(5);
Pro: This is a reasonably simple and efficient approach. A similar idea is discussed by Bjarne Stroustrop on page 156 of The Design and Evolution of C++. Con: You need to write all the little
setters, they aren't JavaBean-compliant (since they return this, not void), they don't work if there are interactions between two values.
3.Use the default constructor for an anonymous sub-class with a non-static initializer:
new C() {{ a = 1; c = 3; e = 5; }}
Pro: Very concise; no mess with setters. Con: The instance variables can't be private, you have the overhead of a sub-class, your object won't actually have C as its class (although it will still be an
instanceof C), it only works if you have accessible instance variables, and many people, including experienced Java programmers, won't understand it. Actually, its quite simple: You are defining a
new, unnamed (anonymous) subclass of C, with no new methods or variables, but with an initialization block that initializes a, c, and e. Along with defining this class, you are also making an
instance. When I showed this to Guy Steele, he said "heh, heh! That's pretty cute, all right, but I'm not sure I would advocate widespread use..."
4.You can switch to a language that directly supports this idiom.. For example, C++ has optional arguments. So you can do this:
class C {
public: C(int a=1, int b=2, int c=3, int d=4, int e=5);
new C(10);
Common Lisp has keyword arguments as well as optional arguments, so you can do this:
(defstruct C a b c d e f) ; Defines the class
(make-C :a 1 :c 3 :e 5) ; Construct an
instance
What about class initialization?
It is important to distinguish class initialization from instance creation. An instance is created when you call a constructor with new. A class C is initialized the first time it is actively used. At that time,
the initialization code for the class is run, in textual order. There are two kinds of class initialization code: static initializer blocks (static { ... }), and class variable initializers (static String var =
Active use is defined as the first time you do any one of the following:
1.Create an instance of C by calling a constructor;
2.Call a static method that is defined in C (not inherited);
3.Assign or access a static variable that is declared (not inherited) in C. It does not count if the static variable is initialized with a constant expression (one involving only primitive operators (like +
or ||), literals, and static final variables), because these are initialized at compile time.
Here is an example:
Program:
class A {
static String a1 = ABC.echo(" 1: a1");
static String a2 = ABC.echo(" 2: a2");
class B extends A {
static String b1 = ABC.echo(" 3: b1");
static String b2;
static {
ABC.echo(" 4: B()");
b1 = ABC.echo(" 5: b1 reset");
a2 = ABC.echo(" 6: a2 reset");
class C extends B {
static String c1;
static { c1 = ABC.echo(" 7: c1"); }
static String c2;
static String c3 = ABC.echo(" 8: c3");
static {
ABC.echo(" 9: C()");
c2 = ABC.echo("10: c2");
b2 = ABC.echo("11: b2");
public class ABC {
static String echo(String arg) {
System.out.println(arg);
return arg;
public static void main(String[] args) {
new C();
Output:
1: a1
2: a2
3: b1
4: B()
5: b1 reset
6: a2 reset
7: c1
8: c3
9: C()
10: c2
11: b2
I hope the above will help you.

Using the Comparator Interface.Please Help.

Hello there,
I am trying out this example regarding the Comparator Interface.
It works fine, but I havent really understood this at all.
It deals with reverse sorting.
import java.util.*;
class MyComp implements Comparator {
public int compareTo(Object a,Object b)
String aStr,bStr;
aStr = (String)a;
bStr = (String)b;
return bStr.compareTo(aStr)
class MyComparator {
public static void main(String[] args) {
// Create a Tree Set
TreeSet ts = new TreeSet(new MyComp());
ts.add("C");
ts.add("A");
ts.add("P");
ts.add("Z");
ts.add("B");
System.out.println(ts)
Output : [Z, P, C, B, A]
I have not understood the following at all:
1) We are implementing the Comparator Interface in class MyComp.
Now where is this being called in the MyComparator class?
2) How is the reverse sorting taking place.?
How is this comparing the different instances of the MyComparator class
when I havent even instantiated the MyComparator class ?
3) How is the interface method compare To(Object a,Object b) being invoked?
Please can some please answer my questions.
Regards

class MyComp implements Comparator {
public int compareTo(Object a,Object b)
String aStr,bStr;
aStr = (String)a;
bStr = (String)b;Your reverse ordering is happening here.
If you were to write
return aStr.compareTo(bStr)
the ordering would be in normal order.
>
return bStr.compareTo(aStr)The comparator that the treeSet uses is declared and instantiated here
TreeSet ts = new TreeSet(new MyComp());
1) We are implementing the Comparator Interface in
class MyComp.
Now where is this being called in the MyComparator
or class? The comparator is being used by the TreeSet to order your entries
>
>
2) How is the reverse sorting taking place.?Explained above. For further explaination look up comparator and String.compareTo()
How is this comparing the different instances of
of the MyComparator class
when I havent even instantiated the MyComparator
or class ?Also explained above
3) How is the interface method compare To(Object
a,Object b) being invoked?Internally by the TreeSet
I hope this helped a little

Medrec example getting unknown error on the web interface

Hi, I've been able to set up my medrec server following the instructions and everything seemed to go fine. I try to go test it on the server and I get an error with the bery helpful error code of "Unkown Error". It appears on every .do file and .jsp files seem to be fine. I have scoured over all my logs and can't seem to find any errors. I have boosted up debug as much as I can and sitll nothing. The only thing that I can see is the following which I'm not completely sure is an eror and not sure how to fix if it is. This is from the admin server log:
<Error> <JDBC> <spuvpars.zko.hp.com> <adminser
ver> <ExecuteThread: '1' for queue: 'weblogic.admin.HTTP'> <<WLS Kernel>> <> <BEA-001151> <Data Source "MedRecTxDataSource" deployment failed with the following error: DataSource(MedRecTxDataSource) can't be created with non-existent Pool (connection or multi) (MedRecPool-PointBase-XA).>
on the managed server (the one running MedRec) there is nothing in the log
I hacve the pools created and everything looks happy

Doubts in XI basics..help me with some practical examples

hi friends,
I am new to SAP XI have some basic doubts. Answer my questions with some practical examples.
1. what is meant by "Business System" and what is difference between client,customer,Business partner,3rd party
2.If a small company already using some systems like Oracle or peopleSoft,if it wants to use SAP products then what steps it has to follow.
3. SAP system means a SERVER?
4.SAPWebAs means a server software?
5.R/3 system comes under SAP system?
6.XI is also one of the SAP module..how it relates to other modules.
7.In one organization which is using SAP modules,each module will be load in separate servers?
8.PO(purchase order) means just looks like one HTML file..customer will fill the form and give it.like this,Combination of many files like this is one SAP module.Is it right assumption..?if so,then what is speciality SAP?
I have an theoretical knowledge about IR and ID and SLD.what are general business transactions happens in any business ?(like who will send cotation,PO) give some practical example for what actually happens in business?..who will do what?and what XI will do?

Hi Murali,
 1.Business System
Business systems are logical systems that function as senders or receivers within the SAP Exchange Infrastructure(XI).
Before starting with any XI interface,the Business systems involved has to be configured in SLD(The SLD acts as the central information provider for all installed system components in your system landscape.)
business system and technical system in XI
2.Third Party
http://help.sap.com/saphelp_nw04/helpdata/en/09/6beb170d324216aaf1fe2feb8ed374/frameset.htm
eg.For the SAP system a Bank would be a third-party which would be involved in interfaces involving exchange of data(Bill Payment by customer).
3.XI(Exchange Infrastructure)
It enables you to connect systems from different vendors (non-SAP and SAP) in different versions and implemented in different programming languages (Java, ABAP, and so on) to each other.
Eg.If an interface involves Purchase Order sent from SAP system to the vendor(Non-SAP system)then,the vendor might expect a file.But the Data is in the IDOC(intermediate document) form with the SAP system.Here XI does the work of mapping the IDOC fields and the File fields and sends it to the vendor in the form of a file.
In short,always the scene is Sender-XI-Receiver.
The Sender and the Receiver depends upon the Business you are dealing with.
4.Business Partner
A person, organization, group of persons, or group of organizations in which a company has a business interest.
This can also be a person, organization or group within this company.
Examples:
Mrs. Lisa Miller
Maier Electricals Inc.
Purchasing department of Maier Electricals Inc.

How to config. different Operations of the same Interface to different BPM

Hi Gurus
   I have a very urgent problem.
   The requirement is like this:
   Customer creates an invoice in A1S and release it. Information of the invoice is retrieved via two service interfaces:
        CustomerInvoiceProcessingInvoiceAccountingOut
        CustomerInvoiceProcessingReceivablesPayablesOut
        with operation NotifyOfInvoice;
   These two interfaces will transfer the information into XI and the information will be filled into a BAPI, BAPI_ACC_DOCUMENT_A1S, to R3. Then the finacial document together with the invoice will be created in the R3.
   when customer cancels the invoice in A1S, Information of the cancellation is retrieved via the same two service interfaces:
        CustomerInvoiceProcessingInvoiceAccountingOut
        CustomerInvoiceProcessingReceivablesPayablesOut
        with operation NotifyOfInvoiceCancellation;
   These two interfaces will transfer the information into XI and the information will be filled into a BAPI, BAPI_ACC_DOCUMENT_REV_POST, to R3. Then the reverse finacial document will be created in R3.
    My solution is like this:
    1. for invoice creation:
     Both messages sent to BPM_1, then send to R3. 3 interface determinations are needed for 3 abstract interfaces.
    2. for invoice cancellation:
     Both messages sent to BPM_2, then send to R3. 3 interface determinations are needed for 3 abstract interfaces.
    My problem is this:
    No matter during creation or cancellation, the same interfaces are triggered. The related receiver determination will distribute the information to both of two BPMs. However the information only contains data of one operaton: creation or cancellation. Error messages will appear in monitor for the other BPM. For example, when customer creates an invoice, the information only contains data of creation whereas it is sent to two BPMs via the receiver determination. the BPM for cancellation surely can not deal with this information then error appears.
    My question is : how can i solve the problem? How can i avoid the appearance of the error? thanks

Hi,
In the receiver determination you can route the message to the RIGHT BPM according to the content of the payload. So each time only one BPM is called.

How can I find out the web interface a module function is executed from?

Hello all,
I was wondering if anybody knows how would be possible de determine the web interface a function is being launched from, within the function.
I've got this function that is used for a exit variable that updates the variable value depending on another variable in a web interface. The thing is that this very same function and variable will be used in many web interfaces and the "source" variable will be different for each mask.
So, for example, mask 1 will have variable 1 as a selector variable and variable X will be updated by it. Then I also have variable 2 in mask 2 as a selector variable and variable X will be updated by it as well.
I want to develop a code, within the function module, that depending on the web interface that is calling it, it will use a source the correct variable and for this I need to know which web interface is calling the function.
I hope to have been able to explain myself clearly. It's a purely technical question.
Thanks in advance.
Best regards.

Hi Francesco,
Are you talking about that ??? )) It will explain you about to get the name of the web page when you are executing an abap function for determining the values of variables...

This is weird: I wrote that document a few weeks ago, it is theorically published on SDN but this is not possible to find it by using the research tool... Maybe because it applies only to BPS in 3.5. I did not have enough time to migrate that solution to BI-IP 7.0.

How do I quickly update the ActiveX automation references in my VIs when the ActiveX interface changes?

Hello all,
I joined a test automation team in the middle of a large project and
inherited a huge set of VIs (over 700) and associated architecture for
this automation (not to mention the several thousand TestStand
sequences). Another part of the project is being developed by our
customer, who is using VB 6.0 to create ActiveX components which we
need to use in LabView to access their hardware. They've already
invested a large amount of time developing these ActiveX components,
and they are not finished -- meaning the ActiveX interfaces will be
changing. Every time they send updated ActiveX components, I have to
re-write many, many VIs including updating a couple strict typdefs.
This process takes way too much time and is mind-numbing and prone to
error or omission.
Unfortunately I can't post any of the VIs because of a NDA. But
perhaps a bit more detailed explanation would help. TestStand calls a
VI to open and get an ActiveX reference for automation (which it stores
in a variant). It will pass this reference into any VI it calls to
perform specific functions through this ActiveX interface. For
example, one VI that may be called passes this automation refnum into
another, which passes it to another, which passes it into another to
get the actual ActiveX reference stored in that variant (through a
Variant To Data call with a strict typedef of the ActiveX component
wired to the type input). [See the attached image of this sample VI
hierarchy: the far left icon would represent TestStand, and the far
right is the strict typedef.] Any of the VIs in the chain might use
ActiveX Property or Invoke nodes, and it can break at any one of those
when the ActiveX component changes. It's easy to fix each one, but
since there are so many VIs it takes a very long time.
Is there any way at all to do a massive search/replace or something to
make the ActiveX references update? I realise that even though
property or method names stay the same from one version to the next,
they are different references. Is there a way to update these based on
name if you give it the base ActiveX reference?
Thanks in advance for any help!

Ben,
Unfortunately I can't post any VIs that would demonstrate the problem
because the ActiveX components are confidential. I'll try to develop
my own ActiveX dll that will demonstrate it, but in the meantime, in
hopes that another picture will help, I've attached an image of a block
diagram (with some names changed to protect confidential information)
of one of the lower level VIs from the hierarchy I posted. In this
example, the "Automation Refnum IN" is an input with a type definition
linked to the strict typedef based on the ActiveX automation dll that
has changed. I updated that typedef, but as you can see the output to
the "Class1" indicator is broken. If I delete the "Class1" indicator
and select Create->Indicator from the Class1 property node, and then
wire the new "Class1" indicator to the connector pane, the VI is fixed
-- at least at compile time. In most cases there is also a runtime
problem where the reference obtained by one of the intermediate
property nodes is null, so the property or method node that uses it
fails (e.g. "_VNManager.Networks" property returned is 0, so the
"_Networks.Network1" property node fails). To fix this problem, I have
to delete the wires between the property nodes, and one by one select a
different property/method, then select the correct property/method and
re-wire. There seems to be a bit of "jiggling the handle" to get it to
work though.
I don't know if the ActiveX developer changed anything in this class,
but if he did, he didn't change the name of this class. I would like
to have to modify the VI only if a class, property or method has
changed name or been removed.
Does that all make sense? Thanks for any pointers or help!

Additional Information:
our questions :
1) why ASA don't check the reverse path route before checking the NAT ?
if it does, the route back to the office is set to the "vpn" interface (route vpn 192.168.20.0 255.255.255.0 192.168.12.1 1), so ASA don't have to check NAT in other interface, currently it's checking the NAT in the "outside" interface even if it's not the route back to the office
2) why it's working for static NAT servers and Not working for the dynamic NAT ones ?
when ASA check a server with static NAT it find a match in the outside interface but even so it discard it and the connection Work. (example 2)
when ASA check a server/host with dynamic NAT (ACL or Network) if find a match in the outside interface but drop the connection
3) we know that this behavior can be solved by adding a NAT exception for the dynamic NAT in the "outside" interface (nat (inside) 0 access-list Inside-NAT-Exceptions) but :
why ASA checking the global NAT even if it's not the correct interface ?
Why it's working for static NAT and not working for the dynamic one ?
Thanks a lot

Hi,
It would be easier to troubleshoot if you shared the complete "packet-tracer" command you used and the full output of the command.
But to me the situation in its current form looks the following.
Example 1
To me it seems this is working as it should. Connection is coming from "vpn" to "inside". There is no "static" configurations between "vpn" and "inside" and there is no "nat" command for "vpn" interface so the traffic should pass normally without any NAT related conflicts/problems as the traffic does not match any NAT configuration.
Notice that the ASA might show some unrelated NAT information in the output of the "packet-tracer" command (commands related to other interfaces). In those NAT Phase sections there is a section saying "Additional Information:" If there is no text after this text that means that this NAT has not been applied. I am not sure why the ASA lists some NAT configurations in the output that are not related. I have seen this in many occasions and do not know the reason and I have not really put any time/effort into understanding why it shows the unrelated information in the output.
Example 2
This seems to be working as expected also.
According to the configuration provided there is no existing NAT configurations related to either the source or destination IP address on the ASA between "vpn" and "inside" interface so the traffic passes through the ASA without facing any conflicts with NAT configurations.
Again, the "packet-tracer" shows NAT information unrelated to this situation. And again the "Additional Information:" section lists no additional information so the NAT listed is not applied.
Example 3 and 4
These tests fail as expected since there is a Dynamic Policy PAT configuration for both internal destination hosts that the remote users are trying to connect to. The problem comes from the fact that the initial direction from remote to internal does not match any NAT configuration and the reverse direction from internal to remote matches the Dynamic Policy PAT and therefore the connection attempt is dropped. The connection must match the same NAT configuration on both directions.
In this situation you would either have to configure NAT0, Static NAT , Static PAT or Static Policy NAT/PAT which all would prevent the connection from matching to the Dynamic Policy PAT (But would match the mentioned type of NAT in both directions as they have higher priority than Dynamic Policy PAT). Typically the prefererred solution would be to use NAT0 though you naturally have the option to use a NAT address if there is any overlap.
Hope this helps :)

Best practice on extending the SIEBEL data model

Can anyone point me to a reference document or provide from their experience a simple best practice on extending the SIEBEL data model for business unique data? Basically I am looking for some simple rules - based on either use case characteristics (need to sort and filter by, need to update frequently, ...) or data characteristics (transient, changes frequently, ...) to tell me if I should extend the tables, leverage the 'x' tables, or do something else.
Preferably they would be prescriptive and tell me the limits of the different options from a use perspective.
Thanks

Accepting the given that Siebel's vanilla data model will always work best, here are some things to keep in mind if you need to add something to meet a process that the business is unwilling to adapt:
1) Avoid re-using existing business component fields and table columns that you don't need for their original purpose. This is a dangerous practice that is likely to haunt you at upgrade time, or (worse yet) might be linked to some mysterious out-of-the-box automation that you don't know about because it is hidden in class-specific user properties.
2) Be aware that X tables add a join to your queries, so if you are mapping one business component field to ATTRIB_01 and adding it to your list applets, you are potentially putting an unnecessary load on your database. X tables are best used for fields that are going to be displayed in only one or two places, so the join would not normally be included in your queries.
3) Always use a prefix (usually X_ ) to denote extension columns when you do create them.
4) Don't forget to map EIM extensions to the extension columns you create. You do not want to have to go through a schema change and release cycle just because the business wants you to import some data to your extension column.
5) Consider whether you need a conversion to populate the new column in existing database records, especially if you are configuring a default value in your extension column.
6) During upgrades, take the time to re-evalute your need for the extension column, taking into account the inevitable enhancements to the vanilla data model. For example, you may find, as we did, that the new version of the S_ADDR_ORG table had an ADDR_LINE_3 column, and our X_ADDR_ADDR3 column was no longer necessary. (Of course, re-configuring all your business components to use the new vanilla column can also be quite an ordeal.)
Good luck!

What is the best practice for using the Calendar control with the Dispatcher?

It seems as if the Dispatcher is restricting access to the Query Builder (/bin/querybuilder.json) as a best practice regarding security. However, the Calendar relies on this endpoint to build the events for the calendar. On Author / Publish this works fine but once we place the Dispatcher in front, the Calendar no longer works. We've noticed the same behavior on the Geometrixx site.
What is the best practice for using the Calendar control with Dispatcher?
Thanks in advance.

Not sure what exactly you are asking but Muse handles the different orientations nicely without having to do anything.

The XElement class explicitly implements the IXmlISerializable interface?

I see a sentence on a training book.
"The XElement class explicitly implements the IXmlSerializable
interface, which contains the GetSchema, ReadXml, and
WriteXml methods so this object can be serialized."
I don't understand it. From
the example, explicitly implements the IXmlSerializable interface is from a custom class rather than XElement class. Is
MSDN wrong?

I mean in the stackoverflow example,the class is a customized one "MyCalendar:IXmlSerializable"
public class MyCalendar : IXmlSerializable
private string _name;
private bool _enabled;
private Color _color;
private List<MyEvent> _events = new List<MyEvent>();
public XmlSchema GetSchema() { return null; }
public void ReadXml(XmlReader reader)
If XElement is a class that implements IXmlSerializable, what is the detail then?
public class XElement : IXmlSerializable
public XmlSchema GetSchema() { *detail*?; }
public void ReadXml(XmlReader reader){*detail*?}
Any source code of XElement class?

How to change the Ethernet Interface name in Solaris 10

I have to install Oracle 10G RAC on three nodes with different ethernet cards, but the ethernet interface name must be the same which is the precondition for Oracle RAC installation.
So I want to know how can I change the ethernet name in Solaris.
For example, the ethernet name in the OS is "ce0", how can i change the interface name "ce0" to "e1000g0".
bash-3.00# dladm show-dev
ce0 link: unknown speed: 1000 Mbps duplex: full
ce1 link: unknown speed: 100 Mbps duplex: half
ce2 link: unknown speed: 100 Mbps duplex: half
ce3 link: unknown speed: 100 Mbps duplex: half
ce4 link: unknown speed: 100 Mbps duplex: half
ce5 link: unknown speed: 0 Mbps duplex: unknown
Thanks in advance.

You can't. The ce or e1000g refers to the driver as well as the adapter itself. The only exception I am aware of is: the ipge and e1000g which both refer to the Intel Pro 1000.I'm pretty sure I've renamed a driver in the past (and all references to it in name_to_major, path_to_inst, driver_aliases, and minor_perm) and had it function just fine after 'plumb'ing it up. However I just tested this by trying to turn a 'pcn' driver into a 'foobar' driver on a vmware box. It looks like everything works except some internal bits of the driver continue to create one file with 'pcn' in the name instead of 'foobar'. And since this is Solaris 10, the /devices filesystem is dynamic and read-only. I can't seem to force the change.
So while this may be possible with some drivers (and maybe only on older versions of the OS), it doesn't seem to be generally possible for all drivers on Solaris 10.
