HowTo: Use package structure in generated code?

Hi,
I'm trying to find out if JCS is meeting my requirements for JSF development. So far it is pretty good, although the lack of support for new components is defeating the purpose of JSF for a great deal.
One of the most terrible things I encountered so far is the fact that I've been unable to get JCS to create a package structure to contain the generated code. In other words, I want JSC to generate the code in "src/com.foo.bar.my.application" instead of just the root of "src/" (where src/ means the source-folder of my project).
This is a real drawback.
Maybe I'm wrong, but in that case it's a plain bug because I can't get it to work.

Admitedly, Creator does not yet offer much flexibility in terms of user-defined package structure. I know you won't like this, but here's a workaround/hack that almost gets to where you want to be.
First of all, the binding between jsp file and backing bean is defined by the relative positioning between the two files. A JSP file at the top level folder maps to a backing bean just under the assigned java package name (something like webapplicationxx). If you create a directory structure for your JSPs and create pages in them, Creator will create a corresponding package hierarchy for the backing beans.
So, one way to contrive a java package structure such as com.foo.bar is as follows (best to start with a new project):
1. Under the Web Pages folder, create a subfolder hierarchy "foo/bar".
3. Under the Java Sources folder, rename the top level package to 'com'.
4. You may now create Web pages in the foo/bar subfolder. You'll probably want to cut & paste the Resources directory into the foo/bar folder if you want to use stylesheets, etc. As the pages are created, notice that a com/foo/bar package structure is created under the Java Sources node where the backing beans are maintained.
One final note, due to a bug in Creator, renaming the package in step 3 does not properly update references to the old pacakge in SessionBean1.java. These will have to be manually changed in the editor. Also note that the ApplicationBean1 and SessionBean1 files must remain at under to top-level package.
We acknowledge this deficiency in Creator and are working to fix it in the next release.

How to use generated code from "Import Web Services" with Cairngorm Framework

I recently downloaded Flex Builder 3 beta 2 and tried out the
wizard that lets you import web services. The code that is
auto-generated makes if fairly straight forward to consume web
services using the object types defined in the WSDL. No longer does
the developer need to decode the XML payload! The only problem I am
having is how does you integrate the auto- generated code with the
Cairngorm framework? This seems like a huge question for anyone who
might want to leverage Cairngorm and the auto-generated proxy code
in the same project (like me).
Here are the problems that I see so far.
1) How do you configure the generated service class to work
with the Cairngorm service locator? The service constructor only
accepts a “LCDS destination string” which implies that
you must use Lifecycle data services. Unfortunately, the project I
am trying to retrofit currently uses a WebService and does not use
data services. All I really need to do is change the endpoint URL
(ie from local to a development server). This issue is noted in the
bug https://bugs.adobe.com/jira/browse/FB-8456. What I think is
needed is a way to set the endpointURI in the Services.mxml file.
2) Even if I come up with a hack around #1, I do not receive
a callback to my IResponder even though I register it immediately
after the method call. I can register and listener function within
my business delegate and receive the callback, but my Command
object, which implements IResponder, does not receive the call back
even though it is registered. From what I read in the ASDocs it
should but it doesn’t for me!
These are the issues I have observed in 3 hours of messing
with this. I hope this makes sense. I would love to integrate
auto-generated web service proxies into Cairngorm but I don’t
see a straight forward way without re-architecting Cairngorm. Has
any one else run across this issue? If so, do you have any insights
on how to proceed? Any help is appreciated.

Since I posted this question, I have abandoned the notion of
auto-generated web services and embraced the good old FDS concept
where the RemoteObject meta-tag does all the conversion work for
me. We are now using the Granite DS package and it is working well
for us. I would love to consume web services, but it just isn't
worth the hassle when all you have to do with Granite (and FDS) is
cast your return objects to the proper object type.
BTW, since this posting, I have investigated competing Flex
app frameworks. After my research, I checked out the PureMVC
framework. Wow!! Cairngorm always left me with an uneasy feeling
and I guess I am not alone. Apparently, Cliff Hall felt the same
way. That is why he started the project. I like his approach alot
more than Cairngorm especially since it includes notifications
which allow me to broadcast my own app level events independent
from the AS Event framework. Check out PureMVC. For what it is
worth, it has my humble endorsement. Cliff was even gracious enough
to acknowledge the other Adobe Consulting guys for their work. Good
for you Cliff, I respect that. Check out a better way at

Using Flash to generate code

Hi i am interested in using adobe flash to generate a code
out of the infomation a user inputs generally the idea is this 1.
User inputs infomation such as age etc 2. a code gets generated 3.
this code links in with the infomation that is given and i can now
type this into flash and the infomation would come up. Can anyone
please tell me is flash able to do this and if so how would i go
about doing it, if not what other ways would there be able to
create something like this
Thank you very much
Liam

You can do this in Flash. A question is do you want all the
logic embedded in the Flash movie including the code generation or
do you want to use server side scripts and any server side data?

I am trying to use generate code in signal express to import into labview.

I get this error when i try to generate code in signal express to export to labview . I have tries the error suggestions but I am still having problems. any help would be appreciated
The version of LabVIEW you are generating code into does not contain all the necessary SignalExpress support files. Make sure you launch the version of LabVIEW with SignalExpress support installed before generating code from SignalExpress. If you want to generate code into more than one version of LabVIEW, uninstall SignalExpress and all versions of LabVIEW except the earliest. Install SignalExpress, then install any other versions of LabVIEW. Copy the files from the vi.lib\express\SignalExpress directory of the earliest installed version of LabVIEW into the same sub-directory location of any other version of LabVIEW in which you want to include support for code generation.

Typically, this problem is repaired by following the directions on the error message. Since it was not, can you please give us more information so we can start determining the cause?
What version or versions of LabVIEW do you have installed? What version or versions of SignalExpress do you have installed? Could you post a file with a listing of the files in <vi.lib>\express\SignalExpress for the version of LabVIEW you are trying to use. You can either post a screenshot (in PNG or GIF format) of the directory dialog or use the command prompt to generate a list to a file (preferred). To generate a list with the command prompt, do the following:
Launch the command prompt from the start menu — Start»Programs»Accessories»Command Prompt
Navigate to the drive you have LabVIEW installed on ( usually C: ) — C:
Change directory to the appropriate LabVIEW directory — cd "\Program Files\National Instruments\LabVIEW 8.2\vi.lib\express\SignalExpress". Change the LabVIEW version to the one you actually are using. Do a directory listing and redirect the output to a file — dir > filename.txt. You can use any full path for the filename.txt. If you specify a simple name, it will end up in the current directory.
Please post your project. Verify that you are using the version of LabVIEW you think you are by launching it before you start code generation.
Thanks for your patience.

How to use wscompile to generate code using a WSDL file?

I am working with JAX-RPC of Java Web Service ver: 1.1. I am intrested in making the WSDL file first and generating Java code from the WSDL file. On the following link:
http://java.sun.com/webservices/docs/1.1/tutorial/doc/JAXRPC6.html#wp80094
it says that wscompile can generate code using a WSDL file..:
<quote>
Table 11-3 wscompile Options
-import : read a WSDL file, generate the service's RMI interface and a template of the class that implements the interface
</quote>
and the wscompile software says this:
<quote>
C:\>wscompile
-import : generate interfaces and value types only
</quote>
can anyone tell me how to generated Java code from a WSDL file. As in, make the WSDL file (e.g. using XMLSpy) and then use that WSDL generate Java code.
Thanks

I'm trying to generate code using wscompile under the struction in JAXRPC_Tutorial.pdf.
I issued the following command:
wscompile.sh -keep -gen:client -f:wsi -verbose config.xml
But I met with the following warning and I cann't find the produced java code, who know why? Thanks in advance!
warning: ignoring SOAP port "EmployeeDBPort": unrecognized transport

Specifying package structure and inheritance for jaxb generated classes ??

Friends,
Now I am tuned up with the sweet JAXB utility...
I need answers to this..
1. How do I specify a package structure in my generated java files?
2. How do I specify inheritance heirarchy to my generated java files ?
I assume, there must be some way of doing this, without opening the actuall source.
any ideas ??
Thanks
Rakesh

how about inheritance heirarchy ? What if i plan to include theses generated classes in my inheritance heirarchy ?
Bhakti, any idea what is the final version release date ? I desperately need answer to this.
Thanks
Rakesh

Use Link Structure of General field Type in code

Hi,
I will use Link Field in my addon, on form (it is not link button).How Can I use this field in VB code ?
In System form is possible set this fiels, but in SAPbouiCOM I did'n find good object.
Can You help me?
regards,
Krzysztof Sala
I use SAP 2007A and VB 2005

Hi Krzysztof,
Unfortunately, the UI API doesn't allow you to have a UserDataSource of type Link. The only way you can add these type of fields to your forms is to reference a UDF from a UDT (or system table in some cases) that has this datatype and use the DBDataSource for the associated table.
Kind Regards,
Owen

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean
by Steve Muench
Overview
BC4J provides automatic facilities for deploying any application module as a stateful EJB session bean. If you want to leverage the features of your BC4J application module from a stateless EJB session bean, it's not automatic but it is straightforward to implement. This howto article explains the details.
For our example, we will create a stateless EJB session bean that uses a container-managed transaction. To keep things simple, let's assume the session bean has a single public method on its remote interface named createDepartment() with the following signature:
public void createDepartment(int id, String name, String loc) throws AppException
AppException is an example of an application-specific exception that our method will throw if any problems arise during its execution.The goal of this article is to illustrate how to use the BC4J application module named com.example.hr.HRApp as part of the implementation of this createDepartment method on our stateless enterprise bean. Let's assume that the HRApp application module has a view object member named Departments, based on the com.example.hr.DeptView view object, based on the familiar DEPT table and related to the com.example.hr.Dept entity object so our view can be updateable.
Creating the Stateless Session Bean
We can start by using the JDeveloper Enterprise Bean wizard to create a new stateless session bean called StatelessSampleEJB implemented by:[list][*]com.example.StatelessSampleEJBBean (Bean class)[*]com.example.StatelessSampleEJBHome (Home interface)[*]com.example.StatelessSampleEJB (Remote interface)[list]
We then use the EJB Class Editor to add the createDepartment method to the remote interface of StatelessSampleEJB with the signature above. We edit the remote interface to make sure that it also reflects that the createDepartment method thows the AppException like this:
package com.example;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface StatelessSampleEJB extends EJBObject {
void createDepartment(int id, String name, String loc)
throws RemoteException,AppException;
}Before we start adding BC4J into the picture for our implementation, our StatelessSampleEJBBean class looks like this:
package com.example;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class StatelessSampleEJBBean implements SessionBean {
public void ejbCreate(){}
public void ejbActivate(){}
public void ejbPassivate(){}
public void ejbRemove(){}
public void setSessionContext(SessionContext ctx){
public void createDepartment(int id, String name, String loc)
throws AppException {
 // TODO: Implement method here
}We can double-click on the ejb-jar.xml file in our project to see the XML deployment descriptor for the bean we just created:
<ejb-jar>
 <enterprise-beans>
 <session>
 <description>Session Bean ( Stateless )</description>
 <display-name>StatelessSampleEJB</display-name>
 <ejb-name>StatelessSampleEJB</ejb-name>
 <home>com.example.StatelessSampleEJBHome</home>
 <remote>com.example.StatelessSampleEJB</remote>
 <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
</ejb-jar>We need to add the extra <assembly-descriptor> section in this file to indicate that the createDepartment method will require a transaction. After this edit, the ejb-jar.xml file looks like this:
<ejb-jar>
 <enterprise-beans>
 <session>
 <description>Session Bean ( Stateless )</description>
 <display-name>StatelessSampleEJB</display-name>
 <ejb-name>StatelessSampleEJB</ejb-name>
 <home>com.example.StatelessSampleEJBHome</home>
 <remote>com.example.StatelessSampleEJB</remote>
 <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
 <assembly-descriptor>
 <container-transaction>
 <method>
 <ejb-name>StatelessSampleEJB</ejb-name>
 <method-name>createDepartment</method-name>
 <method-params>
 <method-param>int</method-param>
 <method-param>java.lang.String</method-param>
 <method-param>java.lang.String</method-param>
 </method-params>
 </method>
 <trans-attribute>Required</trans-attribute>
 </container-transaction>
 </assembly-descriptor>
</ejb-jar>
Aggregating a BC4J Application Module
With the EJB aspects of our bean setup, we can proceed to implementing the BC4J application module aggregation.
The first thing we do is add private variables to hold the EJB SessionContext and the instance of the aggregated BC4J ApplicationModule, like this:
// Place to hold onto the aggregated appmodule instance
transient private ApplicationModule _am = null;
// Remember the SessionContext that the EJB container provides us
private SessionContext _ctx = null;and we modify the default, empty implementation of the setSessionContext() method to remember the session context like this:
public void setSessionContext(SessionContext ctx){ _ctx = ctx; }We add additional constants that hold the names of the J2EE datasource that we want BC4J to use, as well as the fully-qualified name of the BC4J application module that we'll be aggregating:
// JNDI resource name for the J2EE datasource to use
private static final String DATASOURCE = "jdbc/OracleCoreDS";
// Fully-qualified BC4J application module name to aggregate
private static final String APPMODNAME = "com.example.hr.HRApp";We expand the now-empty ejbCreate() and ejbRemove() methods to create and destory the aggregated instance of the BC4J application module that we'll use for the lifetime of the stateless session bean. When we're done, ejbCreate() it looks like this:
public void ejbCreate() throws CreateException {
try {
 // Setup a hashtable of environment parameters for JNDI initial context
 Hashtable env = new Hashtable();
 env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
 // NOTE: we want to use the BC4J app module in local mode as a simple Java class!
 env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
 env.put(PropertyConstants.INTERNAL_CONNECTION_PARAMS,DATASOURCE);
 // Create an initial context, using this hashtable of environment params
 InitialContext ic = new InitialContext(env);
 // Lookup a home interface for the application module
 ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(APPMODNAME);
 // Using the home, create the instance of the appmodule we'll use
 _am = home.create();
 // Register the BC4J factory to handle EJB container-managed transactions
 registerContainerManagedTransactionHandlerFactory();
catch(Exception ex) {
 ex.printStackTrace();
 throw new CreateException(ex.getMessage());
}and ejbRemove() looks like this:
public void ejbRemove() {
try {
 // Cleanup any appmodule resources before getting shutdown
 _am.remove();
catch(JboException ex) { /* Ignore */ }
}The helper method named reigsterContainerManagedTransactionHandlerFactory() looks like this:
private void registerContainerManagedTransactionHandlerFactory() {
SessionImpl session = (SessionImpl)_am.getSession();
session.setTransactionHandlerFactory(
 new TransactionHandlerFactory() {
 public TransactionHandler createTransactionHandler() {
 return new ContainerManagedTxnHandlerImpl();
 public JTATransactionHandler createJTATransactionHandler() {
 return new ContainerManagedTxnHandlerImpl();
}The last detail is to use the BC4J appmodule to implement the createDepartment() method. It ends up looking like this:
public void createDepartment(int id, String name, String loc)
throws AppException {
try {
 // Connect the AM to the datasource we want to use for the duration
 // of this single method call.
 _am.getTransaction().connectToDataSource(null,DATASOURCE,false);
 // Use the "Departments" view object member of this AM
 ViewObject departments = _am.findViewObject("Departments");
 // Create a new row in this view object.
 Row newDept = departments.createRow();
 // Populate the attributes from the parameter arguments.
 newDept.setAttribute("Deptno", new Number(id));
 newDept.setAttribute("Dname", name);
 newDept.setAttribute("Loc", loc);
 // Add the new row to the view object's default rowset
 departments.insertRow(newDept);
 // Post all changes in the AM, but we don't commit them. The EJB
 // container managed transaction handles the commit.
 _am.getTransaction().postChanges();
catch(JboException ex) {
 // To be good EJB Container-Managed Transaction "citizens" we have
 // to mark the transaction as needing a rollback if there are problems
 _ctx.setRollbackOnly();
 throw new AppException("Error creating dept "+ id +"\n"+ex.getMessage());
finally {
 try {
 // Disconnect the AM from the datasource we're using
 _am.getTransaction().disconnect();
 catch(Exception ex) { /* Ignore */ }
Building a Test Client
With the EJB-Tier work done, we can build a sample client program to test this new stateless EJB Session Bean by selecting the bean in the Oracle9i JDeveloper IDE and choosing "Create Sample Java Client" from the right-mouse menu.
When the "Sample EJB Client Details" dialog appears, we take the defaults of connecting to embedded OC4J container. Clicking the (OK) button generates the following test class:
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.example.StatelessSampleEJB;
import com.example.StatelessSampleEJBHome;
public class SampleStatelessSampleEJBClient {
public static void main(String [] args) {
 SampleStatelessSampleEJBClient sampleStatelessSampleEJBClient =
 new SampleStatelessSampleEJBClient();
 try {
 Hashtable env = new Hashtable();
 env.put(Context.INITIAL_CONTEXT_FACTORY,
 "com.evermind.server.rmi.RMIInitialContextFactory");
 env.put(Context.SECURITY_PRINCIPAL, "admin");
 env.put(Context.SECURITY_CREDENTIALS, "welcome");
 env.put(Context.PROVIDER_URL,
 "ormi://localhost:23891/current-workspace-app");
 Context ctx = new InitialContext(env);
 StatelessSampleEJBHome statelessSampleEJBHome =
 (StatelessSampleEJBHome)ctx.lookup("StatelessSampleEJB");
 StatelessSampleEJB statelessSampleEJB;
 // Use one of the create() methods below to create a new instance
 // statelessSampleEJB = statelessSampleEJBHome.create();
 // Call any of the Remote methods below to access the EJB
 // statelessSampleEJB.createDepartment( int id, java.lang.String name, java.lang.String loc );
 catch(Throwable ex) {
 ex.printStackTrace();
}We uncomment the call to the create() method and add a few calls to the createDepartment() method so that the body of the test program now looks like this:
// Use one of the create() methods below to create a new instance
statelessSampleEJB = statelessSampleEJBHome.create();
// Call any of the Remote methods below to access the EJB
statelessSampleEJB.createDepartment( 13, "Test1","Loc1");
System.out.println("Created department 13");
statelessSampleEJB.createDepartment( 14, "Test2","Loc2");
System.out.println("Created department 14");
try {
// Try setting a department id that is too large!
statelessSampleEJB.createDepartment( 23456, "Test3","Loc3");
catch (AppException ax) {
System.err.println("AppException: "+ax.getMessage());
}Before we can successfully run our SampleStatelessSampleEJBClient we need to first run the EJB bean that the client will try to connect to. Since Oracle9i JDeveloper supports local running and debugging of the EJB-Tier without doing through a full J2EE deployment step, to accomplish this prerequisite step we just need to right-mouse on the StatelessSampleEJB node in the System Navigator and select "Run". This starts up the embedded OC4J instance and runs the EJB right out of the current out path.Finally, we can run the SampleStatelessSampleEJBClient, and see the output of the test program in the JDeveloper log window:
Created department 13
Created department 14
AppException: Error creating dept 23456
JBO-27010: Attribute set with value 23456 for Deptno in Dept has invalid precision/scale
Troubleshooting
One error that might arise while running the example is that the database connection information in your data-sources.xml for the jdbc/OracleCoreDS datasource does not correspond to the database you are trying to test against. If this happens, then double-check the file .\jdev\system\oc4j-config\data-sources.xml under the JDeveloper installation home directory to make sure that the url value provided is what you expect. For example, to work against a local Oracle database running on your current machine, listening on port 1521, with SID of ORCL, you would edit this file to have an entry like this for jdbc/OracleCoreDS :
<data-source
 class="com.evermind.sql.DriverManagerDataSource"
 name="OracleDS"
 location="jdbc/OracleCoreDS"
 xa-location="jdbc/xa/OracleXADS"
 ejb-location="jdbc/OracleDS"
 connection-driver="oracle.jdbc.driver.OracleDriver"
 username="scott"
 password="tiger"
 url="jdbc:oracle:thin:@localhost:1521:ORCL"
 inactivity-timeout="30"
/>This is the data-sources.xml file that gets used by the embedded OC4J instance running in JDeveloper.
Conclusion
Hopefully this article has illustrated that it is straightforward to utilize the full power of BC4J in local mode as part of your EJB Stateless Session Beans using container-managed transaction. This example illustrated a single createDepartment method in the enterprise bean, but by replicating the application module interaction code that we've illustrated in createDepartment, any number of methods in your stateless session bean can use the aggregated application module instance created in the ejbCreate() method.

Hi Steve, It4s me again;
About the question I made, I tried with a single assembly-descriptor tag and a single container-transaction tag in the deployment descriptor of the session bean and these were the results.
java.lang.NullPointerException

ObjectFactory in generated Code

I am using xjc using my own parameters like
%JAVA_HOME%\bin\java.exe -cp %XJC_CLASSPATH% com.sun.tools.xjc.Driver -d ./code -p com.eidea.domain po.xsd
which generates the classes in fine manner.
But to compile them the package structure is bit wierd. runtime classes get generated fine, but there is circular referencing between generated interfaces and implementation especially with ObjectFactory which is in the interface directory but needs implementation my javac
JAVA_HOME%\bin\javac.exe -classpath %XJC_CLASSPATH% -d ./classes -sourcepath ./code/com/eidea/domain/*.java ./code/com/eidea/domain/impl/*.java ./code/com/eidea/domain/impl/runtime/*.java
bombs out....
Can anyone give some suggestions or workaround
-Uday

i found the problem i used
%JAVA_HOME%\bin\javac.exe -classpath %XJC_CLASSPATH% -d ./classes com/eidea/domain/*.java com/eidea/domain/impl/*.java com/eidea/domain/impl/runtime/*.java
and it worked

Four layered package structure for ABAP proxies

Hi
I am trying to generate an outbound ( client ) abap proxy in our WAS 640 based ERP system by pointing to a XI message interface on the XI integration repository. I have a single package ZPROXY ( not a main or a structure package ) created in our ERP system to hold the proxy structures ( classes, interfaces ). I have this package assigned to a transport layer ( a common transport layer through which other ABAP objects are to be transported ). Is it really necessary to have a four layer package structures for proxies to be transported and work in the QA/Production system ?

Hi Sudheer,
Can you pls clarify what do you mean by 'four level package structure' ?
Are you referring to the ABAP structures that get created during creating the proxy by SPROXY transaction ? These structures get automatically created. We simply have to write the code using these structures.
Or do you mean the 'package' which is mandatory to create a transportable ABAP object ? i.e. transport from Development to Staging and then Production.

How to use Flex Builders Auto Generated CFCs

OK. Not only have I already gone to a 4 day flex training,
have an advanced coldfusion certification and work with 3 coworkers
who have done the same...none of us can figure out how in the heck
the flex builder's autogenerated cfc's are to be used. No big deal
on the fact that this might be something we simply are encountering
for the first time, but the complete and utter absence of a single
piece of example code or documentation stating how to use this code
correctly is very very very very irritating.
Can anybody, share with me anything about how these CFCs are
to be used correctly. For example. We are using the wizard to
generate an "Active Record CFC" set of cfc's for an example table
contain four fields. We have a data grid that is now populated by
the "getAllAsQuery" function....we would like to implement the
feature of making this dataGrid updateable. We know how to pass
data back and forth and yes we could write our own CFC to do
this...but having it autogenerated is a really neat option...but
the question remains....how does one use them!!!
Any help would be much appreciated. Thanks in advance!

Hi there, what's your name by the way?
What is a VO or DTO, and why would you use it?
This was copy from the Java world, so it's a very OOP principle, basically in the OOP world everything is a class that has methods and properties, and you represent everything with classes, a VO is just that a class that represents an entity in your app. You use it for a few reasons in my opinion:
It allows you to pass strongly typed data between different layers in your app.
It's more verbose, it's a good OOP practice, and also makes debugging and reading you code easier.
It allows easy data type conversion between CF and Flex.
You obviously know how to use the wizards, after you select your table and open the wizard you'll see three different CFC types, if you're using LCDS then select that type if you don't I'll recommend you to go with BEAN/DAO. In Flex Builder you can create a folder link to a system folder, so if you create a folder named MyCFCs and you set this virtual folder to be hold inside c:\ColdFusion8\wwwroot every file that you put in this folder will be place in c:\ColdFusion8\wwwroot so you don't have to manually copy those files.
In this wizard you'll see CFC folder in there you can select your virtual folder, you'll see below the CFC package name this is extremely important to be set right, what is the CFC package name? Basically it's the same folder structure where your CFCs will be located for instance let's say you're gonna place the files in this folder structure c:\ColdFusion8\wwwroot\com\myPersonalDomain\ so your CFC package name will be com.myPersonalDomain.
You'll probably also would like to enable the option: Create an ActionScript value object in addition to CFCs, the folder where you place this file have to mimic the CFCs folder structure so for an instance you'll have to save inside your src folder, inside a folder com, an finally inside a folder myPersonalDomain . src/com/myPersonalDomain, and the AS Package name should be the same as the CFC.
Once you're done and click finish, you'll see for files created, one of the the AS VO , and three CFCs.
yourDataTable.CFC
This is a CFC that creates the VO or DTO in CFC, it has the same properties definition that the AS version has, also the setters and getter for every property.
yourDataTableDAO.CFC
This CFC contains all the code that handles the database access it a could be an insert, update delete or just a read query.
yourDataTableGateway.CFC
This is a bridge between your Flex app and your CFCs, it contains a set of methods commonly use when you access a DB, this CFC invocates the methods in the yourDataTableDAO.cfc and returns an object or an array of objects of yourDataTable.CFC type to Flex.
In Flex what do you have to do in order to use VOs?
Add a reference to yourDataTable.as class
Create a remote object.
Create the event handler(s)
Make a call to the remote object.
<mx:Script>
 <![CDATA[
 import com.myPersonalDomain;
 import mx.controls.Alert;
 import mx.rpc.events.ResultEvent;
 private var myDummyVar:myDataTable;
 private function myEventHandler(e:ResultEvent):void{
 //do Something
 trace(event.result.toString());
 ]]>
</mx:Script>
<mx:RemoteObject id="myRO" destination="ColdFusion"
source="com.myPersonalDomain.myDataTableGateway">
 <mx:method name="getAll" result="myResultHandler(event)"
fault="Alert.show(event.fault.toString())" >
</mx:RemoteObject>
<mx:Button label="Call CF" click="myRO.getAll()" />
Well I hope this would help you, I'm kinda tired this has been by far the largest post I've written.

How Can i use the key file Generated by RSACryptoServiceProvider to encrypt with php?

I need to be able to encrypt data in PHP using a public key generate by .NET(RSACryptoServiceProvider). I will then decrypt the data later in C# using the private key.

As you see this code snippet is a xml format private key. at .net platform,which can use encrypt or dencrypt.
i have try the Extension Crypt RSA ( http://pear.php.net/reference/Crypt_RSA-1.0.0/elementindex_Crypt_RSA.html ) to help me encrypt data by php.but it haven't return a currect result. the data encrypted by php cann't dencrypt by c#.
does the RSA algorithm provider by Crypt_RSA can give a stand result as c#?
BTW :i just use the xmlkeystring like this.

Customer Master using Appended structure KNA1

Hi
We have to update few ZZ description fields in ZAKNA1, which are not part of user interface in XD01/02/03. The available options are such as LSMW, Batch input require code addition through user exit ZXF04U01/ EXIT_SAPMF02D_001.
I would like to use BAPI as we have a plan to use web services. Any idea how to extend the BAPI's such as BAPI_CUSTOMER_CHANGEFROMDATA1 or BAPI_CUSTOMER_CREATEFROMDATA1 using best practice? I donu2019t find any extension structures like other BAPIu2019s have. Without ExtensionIn and ExtensionOut parameters, a BAPI can not be enhanced correct?
The version we are using is ECC 5.0. Any ideas with customer master BAPI will be greatly appreciated.

Just some general comments without having looked at your specific problem. Since you're on ECC 5.0 you cannot use the new [Enhancement Framework|http://help.sap.com/saphelp_nw2004s/helpdata/EN/94/9cdc40132a8531e10000000a1550b0/frameset.htm], which would make such changes more easy...
A rather awkward workaround for extending the BAPI's is sometimes to add append structures to an IMPORT parameter of the BAPI. However, this is a rather dangerous and limited approach, because you might get into trouble depending on where the structures are used (i.e. if you add a field, it might cause harm in other programs that use the structure) and you also have to study the source code to see if you even could utilize those additional fields.
A pretty generic option in lieu of other approaches is to generate a custom wrapper function module around the standard BAPI. Within your custom BAPI you can add the missing fields as parameters, call the standard BAPI and then do the additional updates. The big advantage of such a solution is that
<ol>
<li>Your change/additional logic is obvious (not hidden in a customer exit or BAdI, which are often harder to find when troubleshooting or changing functionality)</li>
<li>Any changes to the standard BAPI will automatically also take effect in your custom BAPI (since you didn't copy the original one); this excludes of course interface changes, but here you anyhow would have to do something...</li>
</ol>
Should you have custom fields that are already exposed on the customer maintenance screens via enhancements, then you might want to consider using the wrapper approach, but simply export the additional data to memory, then call the standard BAPI and within the customer/user exits handling the additional fields fill them via an import from memory.
Cheers, harald

Error: A file found in a source-path must have the same package structure

I use Adobe Flex Compiler (mxmlc) Version 4.1.0 build 16032,I have a file,named CustomGraphContainerController.as,it's directory is c:\controllers,and the GCController.as file is under the same directory,CustomGraphContainerController.as file like follows
package controllers{
import ui.GraphControlContainer;
public class CustomGraphContainerController extends GCController {
public function CustomGraphContainerController(a_graphControlContainer:GraphControlContainer) {
super(a_graphControlContainer);
Then I want to use mxmlc command to compile it,like follows:
C:\>mxmlc c:\controllers\CustomGraphContainerController.as
But it raise compile errors,like follows:
Loading configuration file C:\sdk\frameworks\flex-config.xml
C:\controllers\GCController.as: Error: A file found in a source-path must have the same package structure '', as the definition's package, 'controllers'.
I don't know how to compile the as file with package controllers? Where is wrong? How to use mxmlc to compile it?
Thanks

HI,
You should have one main application class to compile this as code to swf.. So that main application path should be in your proper package structure.. then you can compile you app and as files also...
Thanks

Hi Everyone:

The JDT compiler that Tomcat installs by default is only 1.4 compliant.
You can use ant instead:
remove the common/lib/jasper-compiler-jdt.jar file
place ant.jar file from the latest Ant distribution in the common/lib folder.
If you do this, you also need to use the "javac" argument to catalina.sh.
