Re: Case strange with an example of j2ee tutorial

Sounds like a UI bug in deploy tool. You can always directly set the .xml for the env-entry in the ejb-jar.xml. It would look like this :
<env-entry>
<env-entry-name>DiscountLevel</env-entry-name>
<env-entry-type>java.lang.Double</env-entry-type>
<env-entry-value>0.05</env-entry-value>
</env-entry>
Then in the code :
InitialContext ic = new InitialContext();
Double discountLevel = (Double) ic.lookup("java:comp/env/DiscountLevel");
--ken

Did you try looking up for "jdbc/BookDB" only?

When i run the "asant build" command in
"c:\java\j2eetutorial\examples\web\bookstore1"
directory i get compile error with last few lines as
follows.Did you package the bookstore common files as described in Chapter 3? My guess is that you didn't include bookstore.jar from <INSTALL>/j2eetutorial14/examples/build/web/bookstore/dist/.

Problem with bookstore1 example in J2EE 5 tutorial

Hi everyone. I'm pretty experienced with J2EE but new to the 1.5 version. I'm using the Sun One Server 9.1 and the ant tools. This is referring to the samples in the J2EE 1.5 tutorial. I set my build.properties file and tried to build bookstore1 using ant and then ant deploy. I get the following error.
Deploying application in domain failed; Error loading deployment descriptors for module [bookstore1] -- javax.annotation.Resource.authenticationType()Ljavax/annotation/Resource$AuthenticationType;at com.sun.enterprise.deployment.annotation.AnnotationInfo@4b35d5 Error loading deployment descriptors for module [bookstore1] -- javax.annotation.Resource.authenticationType()Ljavax/annotation/Resource$AuthenticationType;at com.sun.enterprise.deployment.annotation.AnnotationInfo@4b35d5
This error is wracking my brain. If any one could help me with this, I'd really appreciate it.

Well, i haven't checked this forum for a while so by now you've probably figured this out. Anyway, there is a build.properties.sample file in the $JAVA_TUTORIAL_HOME\examples\bp-project directroy. Rename that file to build.properties. Open it and look at it. Really, it should already be filled out. There is a property in there like this
javaee.server.passwordfile=${javaee.tutorial.home}/examples/common/admin-password.txtYou have to go to this admin-password.txt file and set the password to your app server. In mine, I have
AS_ADMIN_PASSWORD=passwordNow, you can go to any web project and run asant. Us asant (which stands for Application Server ant). You can use ant, but using asant will ensure your using the right version. Also be sure your using Java Application Server 9 and the asant that comes with it.

Hello,
Are you sure that you performed all of step 5 in the instructions for packaging the example with deploytool?
Instead of using deploytool, you can also build, package, and deploy the example by running the following commands:
asant build
asant create-war
asant deploy-war
Try this method and see it works. This will be documented in the next version of the tutorial.

The Converter bean example in J2EE tutorial....
Why ConverterHome can refer to Converter without importing Converter first?

* Copyright 2001 Sun Microsystems, Inc. All Rights Reserved.
* Copyright 2001 Sun Microsystems, Inc. All Rights Reserved.
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
public interface Converter extends EJBObject {
public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
import java.io.Serializable;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface ConverterHome extends EJBHome {
Converter create() throws RemoteException, CreateException;
The above code is excerpt from the tutorial sample files.
The problem is that these two classes are not in the same source file. They cannot be since there can be one and only one public class in a source file.
So how come ConverterHome can refer to Converter without import?

The currently executed application, or one of the components it depends on, has been compiled against class file versions that are different from the ones that are available at runtime.
If the exception message indicates, that the modified class is part of the Web Dynpro Runtime (package com.sap.tc.webdynpro.*) then the running Web Dynpro Runtime is of a version that is not compatible with the Web Dynpro Designtime (Developer Studio or Component Build Server) which has been used to build + compile the application.

Case structure with more than 200 cases, slower lab view app

Problem Description :
i am currently making a vi which compose of a simple case structures, a case structure with more than 200 cases, what i noticed is that the more i added cases the slower the labview reacts, it takes time for me to route wire on each of the cases.
i dont know if there are any setting in the labview environment that i can increase the buffer size? i dont know... but its getting slow (only on the
vi with more cases in a case structure)
mytestautomation.com
...unleashed the power, explore and share ideas on power supply testing
nissanskyline.org
...your alternative nissan skyline information site

Can you clarify what you mean by "slow". Does it run more slowly or does it feel sluggish during editing?
Could you attach the actual VI?
Overall, I agree with the notion of local variable overuse. For example, you read the same local variable twice in the same case. Is there a need for this? Is there a chance that it varies between the two reads? Typically, you would place the terminal in front of the case structure and wire to all the locations where you need the value. This ensures that the data is consistent. Still, this should not cause any slowdown problem.
(On a sidenote, the code in the upper left corner is inefficient. You convert the same data to lower case with each iteration, so you might want to place this before the loop and do it only once (well, if you are lucky, LabVIEW will fold the operation, but still....). Also your "index array" operation can be replaced by autoidenxing of the 2D array on the outer loop boundary.)
LabVIEW Champion . Do more with less code and in less time .

Can anyone explain A2A & B2B AND BPM & ccBPM with an example..

Hi All..
Can anyone explain me A2A & B2B
and BPM & ccBPM with an example....
NOTE: i dont need definitions but examples..
i am bit confused with this stuff....
Thanks in advance....
Cheers,
raghavesh

Hi ,
A2A & B2B
This thread explains you the difference between A2A and B2B.
Re: A2A Vs B2B
BPM & ccBPM both are same....
BPM is used to implement work-flow spanning across multiple application system against embedding the parts of work-flow in application system. Apart from this it also help achive other scenarios like, bridging synch and asynch systems, alert mechanism, multi mapping etc. Check the BPM overview document in SDN download section.
Check out the use cases discussed at http://help.sap.com/saphelp_nw04s/helpdata/en/de/766840bf0cbf49e10000000a1550b0/content.htm
BPM is mainly used in senarios where extra functionalities are to be done with the source message which cannot be done using the normal mapping and user-defined functions, like
-->Collecting of messages till a certain count or for a specific criteria.
-->Merging messages
-->Spliting messages
-->Processing of error files and sending to specific location and sending alerts.
-->Parallel processing of two criterias at the same time can also be done using BPM.
some weblogs on BPM...

Code SE18 is used to Identify the BADI available.
Look for the string 'CL_EXITHANDLER' in the standard program. This is a class which has a method 'GET_INSTANCE' which is used to trigger BADI's from the Standard Program. The interface parameter for this static method 'EXIT_NAME' is used to pass the BADI to the method.
Open Standard Program and do a global search 'CL_EXITHANDLER'.
SE18 > give the BADI name found through above search.
CUSTOMER_ADD_DATA > which has a method SAVE_DATA.
T.Code SE19 is used to Implement BADI.
SE19 > give the implementation name > Give the Definition name as CUSTOMER_ADD_DATA and the Short Text.

What are BAdIs?
-> is an anticipated point of extension these points act like sockets and exist in the original source code
-> based on ABAP Objects. BAdI defines an interface that can be implemented by BAdI-implementations that are transport objects of their own
->Important! There are 2 roles: Enhancement Option-provider & Implementer.
-> In the above context, Enhancement Implementation can be done only if option (hook) is provided by the Option-provider. In simple words there are no implicit BAdIs.
Note: In the following slides, Definitions are created so as to understand the method of BAdI definition & for example purpose. As stated above this is the role of Enhancement Option-Provider.
Classic BAdIs already exist since SAP Release 4.6
BAdIs have been Re-implemented in ECC7.0 under the new Enhancement Framework & Switch Framework
Classic BAdIs
To understand what a powerful pattern a BAdI is, we will now define & then implement a BAdI
BADI Class is created automatically.
The various options are described below in detail:
1. Enhanceable: Enhanceability of filter types can only be specified for filter-dependent BADI definitions under very special conditions. For example, the domain belonging to the filter type must be linked with a value table that is of the type E or G. A BADI implementation can then be created in one step by creating a new filter value that is automatically entered into the value table at save and also copied into the transport order of the BADI implementation. In addition, it is also possible to create a new filter value and, at the same time, a BADI implementation with the same name. Naturally, you can also specify existing filter values.
You should select this feature if there is a prerequisite that a new filter value is created together with a new BADI implementation - that is, that BADI implementations are not created solely with existing filter values, although this, too, is possible.
2. Multiple-Use
3. Filter-Dependent
Instance Methods can access all of the attributes of a class and can trigger all events of a class. Static Methods can only access static attributes and static events.
Exceptions:
Events:
Events can be defined in classes or in interfaces. Corresponding methods can trigger these events with the RAISE EVENT statement. Each class (or interface) that is going to handle the corresponding event must implement a relevant handler method, and register it using the SET HANDLER statement. When an event occurs, the system calls all of the handler methods registered for that event.
Like method definitions, events have a parameter interface. The only difference is that events may only have EXPORTING parameters.
BADI : Businees Add IN's
Business Add-Ins are SAP enhancement technique based on ABAP Objects.
Where the SAP standard program is not going to fullfill the client requirement , we are going to add our own program to SAP standard program, without changing the standard prog.
Each Business Add-In has
at least one Business Add-In definition
a Business Add-In interface
a Business Add-In class that implements the interface
Each BADI has two different Views.
1.Definition view
2.Implementation view
T.C for BADI Definition is SE18.
T.C for BADI Implementation is SE19.
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
Set flag field "Buffer trace"
Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
Push the button "Deactivate Trace".
Push the button "Display Trace".
The popup screen "Set Restrictions for Displaying Trace" appears.
Now, filter the trace on Objects:
V_EXT_IMP
V_EXT_ACT
Push button "Multiple selections" button behind field Objects
Fill: V_EXT_IMP and V_EXT_ACT
All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.

How to develop BADI
Rewards if useful.

Can we use applets as user interfaces with sockets, RMI and J2EE

Dear Sir or Madam,
Since I am a TA for software architecture class, some one ask me the following question: I think the answer is "No" based on the document on http://java.sun.com/sfaq/
How I answer the quesions? Looking forward your help!!!
1.You may have 2 applets and 2 html files. One applet with one html file may stay at a client PC and run on this PC, and the other applet with the other html file may stay at a server PC and run on this PC. In this case, all the applets are run locally.
2.Could applets works with sockets, RMI and J2EE?
3.Can we use applets as user interfaces with sockets, RMI and J2EE?
Thank you very much!
Best regards,
Jing

The scenario you paint doesn't quite make sense. The "server PC" wouldn't be running an applet, normally, since applets are by definition in a web browser page, and most likely involve user interaction, and "server processes" generally are done without user interaction.
The security rules around applets are that -- by default -- applets can connect with sockets ONLY to the server from whence the applet was loaded. RMI uses sockets (J2EE is too broad a spec) and hence RMI calls would also be limited to the server from whence the applet was loaded. Within that limitation, an applet could open all the sockets it wants, so long as they are all on the server from whence the applet was loaded.
If you want two applets on two different systems to communicate with each other, the simplest way is to have them rendevous through a server process on the server(s) from whence each applet was loaded. Maybe it's PC-a <-> server-a <-> server-b <-> PC-b ...? Or maybe PC-a and PC-b both are talking to the same server.
The limitation is rooted in the security subsystem. You can specify a policy file and override anything in the security subsystem. That does mean signing the applet and then cajoling the user into agreeing to grant greater levels of security than the default. In such a case you can open sockets more broadly and then PC-a could talk directly to PC-b without going through any servers.
