Switching datasources based on method names in an ejb

Hi All,
We have an entity bean that has read, insert, delete and update operations in it using bean managed persistence and container managed transaction. The read operation is a bit complex and we have a stored proc to do that. The stored proc is so complex that it invariably had to have a temp table (#table in sybase) to process it efficiently. The database is configured not to support ddl statements in TRANSACTIONS for valid reasons, SELECT INTO statement is considered ddl. On the other hand, other operations like insert, delete and update should support transaction.
I am inclining towards using a non-transactional datasource for 'read' and a transactional datasource for other operations. My question to you all?
1. Do you foresee/experienced any problem using the two different datasources for different operations in an entity bean.
2. Is there a chance for deadlock/transaction timeout?
3. Is this something against best practices in ejb world?
I tried changing the transaction attribute of just the 'read' operation to 'notsupported', but it did not when I was using a transactional datasource.
Your input is highly appreciated.
Thanks,
Ilyas

Can you customize your deployment based on VM name

I know it is possible to customize your deployment by mapping your PC based on MAC or serial number using the MDT database. However, is it possible to do this by just the VM name alone? (I would think the same challenge apply to both ESX or HyperV).
If I could go ahead and create a serial of VM call VM01 to VM10, how can I have MDT deploy Task Sequence 1 to VM01 to VM05, while deploy Task Seq 2 to VM06 to VM10? As the VM doesn't have any netbios name of predefine MAC address yet ? Any idea
would be appreicated

Hi,
The answer is no, you couldn't customize deployment based on VM name.
Customize deployment by mapping PC based on MAC or serial number using MDT database is completely different with mapping PC name. The first one is based on hardware query, seconde one is based on software level.
As we know, WMI command can be used to obtain information of Computer Hardware, software, etc. While in WinPE phase, it only could be used to obtain hardware information, the command like
Get -WmiObject win32_computersystem should be works properly, but it won't be work if you try to obtain VM name by using WMI command, WinPE doesn't support these command to obtain VM name, it only works at host system. That's
to say, we didn't have method to obtain host VM name in guest machine. Therefore, if you try to mapping your PC based on VM name, it would be failed.
For more information about WMI, you can refer to the link below for more details:

Extracting method names from JNI probes

Hello.
I would like to use the Call* probes from the hotspot_jni provider. These probes provide as argument a "method id". My question is how I can extract, for instance, the method name from this ID. I saw that JNI provides a method "GetMethodName" but being a dtrace novice, I am unsure how to obtain a handle to the JNI api from within dtrace.
Any hint would be greatly appreciated.
Best wishes,
Eric

Actually, it can be done. Otherwise, how do you think debugger shows variables and formal parameters?
You should compile your aplication with debuginng information (for details see tools doc). Then you have 3 options:
1) run application under debugger and use JVMDI to get everything you want;
2) use bytecode libraries (BCEL, CGLib etc) to read class file and fetch required information through their API
3) write your own class file parser based on class file format described in Java Virtual Machine Specification
First way is quite complex and is definitely not for "production use".
Second way is the best in case you have time limitations, but size of your application will be increased because of thrid-party libraries.
Thrid way is the best if you have application size restrictions and have enough time to write simple class file parser to fetch that specific information (1-2 days depending on your experience).
Have fun ;)

Channel URL to contain object and method name

Hi,
There are many WEB features and filters that are based on the URL path or paramters.
BlazedDS uses the same URL to send all the remote object calls.
I can add more and more channels and map each remote object to one of the channels but it doesn't scale and even with it all the methods on the same object will look the same.
I know that the binary body contains the service name and method name , but this is not enough .
I need to have the URL path/ parameters to contain the service and method names.
Is there any way to control the URL in the remote method beside of the set channel?
Shlomo.

OK,
I think I found the way.
The API of the RemoteObject presents the endPoint property:
'"This property allows the developer to quickly specify an endpoint for a RemoteObject destination without referring to a services configuration file at compile time or programmatically creating a ChannelSet. It also overrides an existing ChannelSet if one has been set for the RemoteObject service."
It means that before every call to a method I can set the end point to something like "http://.../messagebroker/amf?serice=MyService&method=MyMethod...

SSDT vs 2013 and Clr function, call a Clr method name dynamically using SQLCMD variables

Hello,
My question is this, hopefully this makes sense:
How could I got about doing this, inside a SQL function, I would like to re-name the Clr method call based on a SQLCMD variable?
I have a Clr project to encrypt/decrypt data, there are different method names depending on the deployment types.
For the definition of a function called dbo.EncryptThis, I would like to use a SQLCMD variable to change the name depending on SQLCMD variables. This works fine in SQL Server Mgmt studio, but VS 2013 fails to recognize the SQLCMD variable and the build fails
with: "Error
1
SQL71521: A method with a matching signature was not found in the loaded assembly.".
THis code works fine in SQL Server Mgmt Studio, but fails to build in the SSDT project.
In the SSDT project I have the SQLCMD variable defined and think I have SQLCMD mode enabled, by doing this:
Right click file > Execution Settings > SQLCMD mode
CREATE FUNCTION [dbo].[EncryptData]
(@str NVARCHAR (MAX))
RETURNS NVARCHAR (MAX)
AS
EXTERNAL NAME [CryptoClrAssembly].[LibName].[EncryptData$(MethodName)]
Is this even possible in SSDT? or would I have to do this in a post-deploy script?

Hi Kevin,
Thanks for the info.
Bummer, so the only other solution I have is to create a post-deploy script to change the function based on a SQLCMD variable or other logic?
What would be really cool, would be if during the build process the SQLCMD variables would get replaced with the default value to the SQLCMD variable, thus would allow to build the project. Also, during deployment, if someone entered an incorrect method
from the assembly it would just fail.

Using oc4j to generate interfaces from wsdl produced improper method names

The method names that were produced from the opperations in my WSDL, generated an interface file with incorrect method names. The name went from "DoTest" in the wsdl to "doTest" in the Interface file.
I double checked and all the cases are correct in the wsdl.

Obviously one could rename the operation to that standard, but that doesn't exactly strike me as being anything other that a work around for a bug.
WSDL provides a contract in which multiple languages have to conform to a set of interfaces, and it's not exactly good to have a tool, just a assume the contract for an interface is wrong.
I could argue that I'm only doing Java on the front end and .Net on the client side and that they don't neccessarily follow the Java convention, nor should be constrained by it.
I do agree with you that they probably just followed the convention when writing to code generator and just happened to pick up the convention. They just need to fix it now.

Oracle SQL Developer error - "The file-based source procedure Name is not present in the database."

I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name> is not present in the database. Was it compiled?'
instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

Sounds like you do not have the correct privileges. What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest? If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
The role SELECT_CATALOG_ROLE
The system privilege SELECT ANY DICTIONARY
And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
The role EXECUTE_CATALOG_ROLE
The system privilege EXECUTE ANY PROCEDURE
Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.

Gary

How to convert a String variable as class name and method name?

i have two classes
class Student
public String insertStudent(String sname)
{ return("Student has been inserted "); }
class Teacher
public String execute(String methodName, String className)
{ //return statement of the method 'insertStudent' in the class 'Student'; }
}Now, i have a class with the main method. Here, i would like to call the method *'insertStudent'* of class *'Student'*
using the method *'execute'* of class *'Teacher',* passing the method-name and the class-name (viz. insertStudent, Student) as the
String parameter.
Can anyone please help me out. Thanks

You should have just added that as a comment on your [initial posting|http://forums.sun.com/thread.jspa?threadID=5334953] instead of starting a new thread.

Why oh why? What do you want to achieve?
Let me tell you: there is a way to do what you try to do, but it's not recommended and should be used only very sparingly. Especially not in anything like your code, that resembles normal business logic (as opposed to an application framework such as Spring, for example).
Can you explain what exactly you want to do with that? Why should a Teacher be able to call any random method ony any other class. And what good would that do?

Receiver File adapter: dynamic folder name based on file name

Hi there,
is it possible to set up one communication channel that will use different target folders based on file name?
E.g.
File abcdef will be saved to /root/abcdef/abcdef or /root/abcdef/abcdef.txt
File xyz will go to /root/xyz/xyz or /root/xyz/xyz.txt
I know I could use Sender/Receiver Service, Interface/namespace or data from message for variable substitution but could not find an easier solution for this scenario than to create multiple communication channels.
Thanks.

If you haven't a message mapping, then you can create only an interface mapping with an abap mapping.
In your abap mapping:
DATA l_record type mpp_dynamic.
l_record-namespace = 'http://sap.com/xi/XI/System/File'.
l_record-name = 'FileName'.
l_record-value = "your filename"
dynamic_configuration->add_record( l_record ).
l_record-namespace = 'http://sap.com/xi/XI/System/File'.
l_record-name = 'Directory'.
l_record-value = "your directory ".
dynamic_configuration->add_record( l_record ).
Afther that, you must activate Adapter Specific Message Attributes (directory and/or filename) in your target communication channel .

Carme.

Failed to parse method name:

Hi,
I've the following environment:
- Sun Solaris
- WL 61 without service pack
- jdk 1.3.1
I wrote a simple Session Bean and make it IIOP enabled.
For the Java-Corba client I use an IDL which describes
the interfaces of the remote and home interface of the
Session Bean.
Everything works fine, that means I get the WL's NameService,
home and the remote object. If I call a method of the remote
object I got the following message:
<Info> <IIOPEndPoint> <failed to parse method name: foundUnkownSubscriber>
I found something in you newsgroup and you said the we should
use SP2. Where can I get this SP2?

What is wrong in my solution? Here is my simple IDL-File:
module prototype{
     exception CallBackException {
     interface CallBack {
          void foundUnknownSubscriber( in string MSISDN) raises(CallBackException);
     interface CallBackFactory {
          CallBack create();
Thanks.

Get the method name

hi
can anyone know how to get the name of method from its catch block.
For example
i have a class called Hello.java
and inside that a method called display();
and i have a written the code inside a try catch block.so when an exception occurs i want to create a log file
i got the class name using this.getClass().getSimpleName()
so is there any way to get the method name , where the catch is written. (here in example i should get it as "display")
plz help me
im in great need.
hope u understood my doubt.

Use a logging framework, and name the loggers well & use meaningful messages?
Or create a Throwable, [fill in|http://java.sun.com/javase/6/docs/api/java/lang/Throwable.html#fillInStackTrace()] the stack trace, get the required StackTraceElement and [get the method|http://java.sun.com/javase/6/docs/api/java/lang/StackTraceElement.html#getMethodName()] from this.
