Document java methods/classes?

Hi!
I normally document java methods using UML sequence diagrams but was wondering whether there is a better way using xsd schemas that I can then use to create the classes. Is there any standard annotation/framework?
Thanks.

No please.. I just want to know if you have used it while programming. Like "an abstract class can be used to put all the common method names in it without having to write actual implementation code."That would describe an Interface better than an abstract class. Abstract classes usually have at least some implementation.
I want to know its usage in programming, not just a definition. I guess you understand what I am looking for.Yes, and I gave you one: java.util.AbstractList. It can be found inside the src.zip in your JDK directory and it is a pretty good example for an abstract class that provides some implementation and defines exactly what is necessary to make a full List implementation.

How do I deal with a Java method which returns a class object?

Hi, I am using JNI to talk to some Java code from c++;
I have a java method in class B that is defined as
class B{
A[] As;
A getA(int i){
return As(i);
where A is one of my classes.
I would like to know the code to deal with a returned object of type A and then how to access the variables in A from c++.
I have defined my method pointer as :
env->GetMethodID(B, "getA", "(I)A;");and have the jclass object of type A.
Would I do something like jclass A_CLASS = env->FindClass("A");
jobject A_OBJECT = (A_CLASS)env->CallObjectMethod(B,getA, i) ; If so, how do I then access the fields in A_OBJECT? Please let me know, thanks.

Thanks but this doesn't really help. I know how this is done in Java (see below).Presumably you also understand how that code will fail. At least based on what you have posted here.
I do not understand the syntax to do the equivalent thing in JNI, specifically, how to cast the returned object from the CallObjectMethod function to be of the appropriate type, namely A, and then how to access those fields. You don't cast it. Didn't do so in your java code either.
But you define how you are going to attempt to access any object in JNI. If you mess up it fails.

How to use java.lang.Class.getMethod() and java.lang.reflect.Method.invoke(

I want to call a specified method of one class dynamically. I use the method
"getMethod()" in package "java.lang.Class" to get method and "invoke()" in
" java.lang.reflect.Method " to invoke method.
The problem is as following :
1. There are two argument in this method "getMethod(String MethodName , Class[] paremterTypes)" in package "Class". I have no idea about the second parameter " Class[] parameterTypes ".what does the argument exactly mean ?
2. There are two argument in the method "invoke(object obj, object[] obj)" in package "Method".
I have no idea about the second parameter "object[] obj ".what is mean ?
I pass " null " value to it and it works.But i pass anothers ,jvm will throw exception.

I have a generic Method Executer that has a method like
public Object execute(String className, String methodName, Object args)
    String fullClassName = packageName + className ;
    Class delegateClass = Class.forName(fullClassName);
    BaseDelegate delegate = (BaseDelegate)delegateClass.newInstance();
    Method method = null;
    if (args == null)
        method = delegateClass.getMethod(methodName, new Class[] {});
        obj = method.invoke(delegate,new Object[] {});
    else
        method = delegateClass.getMethod(methodName, new Class[] {args.getClass()});
        obj = method.invoke(delegate, new Object[]{args});
   }This seems to have problems when I call the method from a class like:
execute("CategoryDelegate", "getCategoryById", new Integer(4144));(I get a NoSuchMethodException)
The method I am trying to execute in CategoryDelegate looks like:
public Category getCategoryById(int categoryId) throws DelegateExceptionI think it has to deal with the difference in the way we handle Primitive Wrappers and Objects. Wrapper we have to use Interger.TYPE and with the rest of the Objects we have to use obj.class.
Am I doing something wrong here? Any suggestions to make it work for primitive wrappers as well as Objects?

How do I find class name I should import for java method name

If I have the class name I know how to look in java docs list for methods.
If I have a method name but don't know the class,
how do I find class name I should import to use the java method name?

I'm not sure the other reply answered your question. If you truly don't know the class name, one approach would be a Google search. Another approach works if you have an IDE. Eclipse, for example, can find the class for you (assuming it's on your classpath) & automatically import it for you. Ctrl-Shift-O normally does the trick.

UI Error 'Method clone not found in class java.lang.Class'

When attempting to view an application window in the User Interface error I receive the error 'Method clone not found in class java.lang.Class'. The window will run correctly when I execute the application and other objects on the window are displayed correctly in the UI editor.
Within the window class I have used the following line of code to clone a reference list of values that is loaded just once when the application starts up: -
dsDefaultComboBoxModel priorityComboBoxModel = (dsDefaultComboBoxModel) dsReferenceLuLists.priorityComboBoxModel.clone();
And then this line of code to create a combo box: -
dsGuiComboBoxRefelu priorityComboBox = new dsGuiComboBoxRefelu(priorityComboBoxModel,ReportWindowSql.priorityCodeBuffer);
And then later on the combo box is displayed.
detailsArea.add(priorityComboBox, new XYConstraints(250,10,dsGlobalVariables.gvFieldWidthLarge,-1));
'dsDefaultComboBoxModel' is defined as follows: -
public class dsDefaultComboBoxModel extends DefaultComboBoxModel implements Cloneable
public dsDefaultComboBoxModel()
public Object clone()
try
return super.clone();
catch ( CloneNotSupportedException e )
// Shouldn't happen.
throw new InternalError( e.toString() );
This error occurs using the latest v903, but was also present in previous versions of JDeveloper.
At the moment this means that I did to execute the window in order to see all of the GUI elements that are displayed. As on option I could use something other than the clone method, but it seems to be such a nice way of copying the static reference lists.
Thanks for any help.

Hi Darren,
My guess is that since DefaultComboBoxModel doesn't implement Cloneable, you can't call super.clone(). Does your code compile?
Later.

Web dynpro dc compoent controller method call from Java dc class file

Hi All,
Is it possible to call a wd java component controller method from a java dc class file?
I have declared wd java dc as used dc in java dc.Any poiters for the same would be really helpful.
Thanks in Advance.
regards
Radhika Kuthiala

Hi,
short answer: No.
1. using WD references outside of WD DCs is unsupported and will at least show a warning when you try to deploy. Correct usage of runtime dependencies is not predictable.
2. WebDynpro Controllers have a lifecycle that is controlled by the Framework. Even if you manage to initialize a Controller via "new" and use a method, the Controller will never have all the state-information it contains when started regualary. (think of mapped context, context attributes in general, code called in wdInit ...) I would suppose it is possible to implement a runnable low-profile example that still works, but as soon as you try to use "higher" concepts of WD (which would be the only reason to use a WD Component Controller at all), you will definitely fail.
3. Think of it as calling EJBs Session Beans via "new", but more complex.
hope that helps

NullPointerException at java.lang.Class.forNameImpl(Native Method)

Hi All,
We installed an enterprise application using Websphere Application Server 6.1 and we use Java 1.5.0_18. We encountered the following error while testing the application:
[6/07/09 18:32:56:825 EST] 0000002b SystemErr R java.lang.NullPointerException

<the remaining part of the stack trace has been removed as it contains the names of our application specific classes>
Could you please let me know the root cause of this error?
Thank you.

I would double- and triple-check that. A null classname string is almost certainly the cause here.

Intermittent problem in Coldfusion 9, BlazeDS with Java Service class and CFCProxy

If that title doesn't scare you, you might be able to help.
I believe there is a bug in Coldfusion 9's version of CFCProxy.
Tech Stack:
Flex Application
BlazeDS (stock with CF9)
Java Service class (java-amf BlazeDS endpoint)
Coldfusion business tier, invoked by the Java Service class using CFCProxy
Tomcat 6 on Java 1.6
Linux or Windows servers, both exhibit same behavior
SQL Server database
Problem:
When Flex calls a Java service method through BlazeDS that invokes a Coldfusion CFC through CFCProxy, and the method called in the Coldfusion CFC includes a large query (10 fields, 1000+ records returned), we intermittently (1 out of ~5 times) receive the following exception:

Attempts to diagnose:
These things remove the problem:
CF8 works perfectly with the identical code, never fails.
Calling the same Coldfusion CFC method with the large query (10 fields, 1000+ records returned) from another CFC 100+ times never fails.
Using a Coldfusion service class (a "my-cfamf" BlazeDS endpoint) never fails. However, we need to use a Java service class because we are using ~40 Java value objects (VOs) that correspond to ~40 auto-generated Actionscript VOs. BlazeDS won't correctly deserialize the Actionscript VOs into the Java VOs with a Coldfusion service class.
If I replace the large query with a Sleep(5000) instead, it never fails.
These things don't remove the problem:
Using the latest Microsoft JDBC driver doesn't help.
Even if the Coldfusion method returns an empty resultset (i.e., just calls the query and doesn't do any other work or return anything), the call still fails intermittently.
If the Coldfusion CFC with the method in question is instantiated and stored in SERVER scope as a singleton across multiple requests with CFCProxy, doesn't help.
Different large (1000+ record queries) all fail in the same way.
Caching the query doesn't help
Changes in the datasource configuration doesn't help
Using the older version of BlazeDS doesn't help
With all of these tests, I believe it comes down to a problem in the combination between CFCProxy and large queries. There may be more to it, but that is what we've narrowed it down to.
Any insight would be very welcome.

Passing variables frm xsl to a java method

i have an xml message (that is passed to me from another process) as follows:

XSLT mapping with Java helper classes

Hi,
I'm trying to implement a XSLT mapping to convert my request to a specific soap request message format for this I'm calling some methods from a java helper class. I have imported the jar file into the archives. When I tried to test the interface it keeps complaing there is some exception but doesn't give me the exact error. Has any one called any java helper classes with in XSLT mapping, if so I would appreciate if you could help me with this. Here is the code from xsl.

Any way (event) to call Java method after view created in JSF 2.0

Hi,
I am using JSF 2.0 Mojarra's implementation.
I am interested to know if there is a way to call Java methods before and/or after view has been restored.
I wanted to initialize data for my page in this Java method.
I could see there is an event class PostRestoreStateEvent added in JSF 2.0. How to use it?
I tired to use f:event element as below, but it does not work. Can anyone share anyother idea to achieve this behaviour?
<f:metadata>
<f:event type="postRestoreState" listener="#{employeeLoadBean.loadAfterRestoreView}"/>
</f:metadata>
Regards,
Kishore K S

Hi,
The problem is solved as below.
<f:metadata>
<f:event type="javax.faces.event.PostRestoreStateEvent" listener="#{employeeViewEventListener.postRestoreState}"/>
</f:metadata>
The above calls the Java method #{employeeViewEventListener.postRestoreState} whenever View has been restored.
It was not working when shortName of the event (ie., postRestoreState) is given and throwing ClassNotFound exception.
Regards,
Kishore K S

Calling the Java Method in PL/SQL Java Stored procedure errors out

Hi,
I could not find a suitable thread to post my PL/SQL question so iam posting it here.........
I have written a java class by name XYZ which has a method ABC for which there are 9 arguements being passed and its a VOID method.
This java class has been loaded into ORACLE using DBMS_JAVA.LOADJAVA pkg, Now this class is being called in the oracle as a JAVA Stored procedure...... When ever im trying to call the procedure it throws the following error
ORA-29531: no method
*Cause:    An attempt was made to execute a non-existent method in a
Java class.
*Action:   Adjust the call or create the specified method.
The code snippet as follows
JAVA CODE:
Class xyz
public static void Abc (String hostName,
int port,
String serviceURL,
String soapAction,
int timeOut,
String wsUser,
String wsPasWd,
String keyStore,
String keyStorePasWd)
//method implementation
JAVA STORED PROCEDURE:
create OR REPLACE procedure ABC_JAVA_SP_CALL
(p_hostname in varchar2, p_port in number, p_serviceurl in varchar2, p_soapaction in varchar2, p_timeout in number, p_wsuser in varchar2, p_wspasswd in varchar2, p_ks_path in varchar2, p_ks_passwd in varchar2)
as
language java
name 'xyz.Abc(java.lang.String, int, java.lang.String, java.lang.String, int, java.lang.String, java.lang.String, java.lang.String, java.lang.String)';
When i try to call
declare
p_hostname varchar2(100);
p_port number;
p_serviceurl varchar2(100);
p_soapaction varchar2(100);
p_timeout number;
p_wsuser varchar2(100);
p_wspasswd varchar2(100);
p_ks_path varchar2(100);
p_ks_passwd varchar2(100);
begin

p_port ,
p_serviceurl,

end;
This thing ends up with

Remote Object - not able to get the returned value from java method

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">
<mx:Script><![CDATA[
import mx.controls.Alert;
import mx.binding.utils.ChangeWatcher;
import mx.rpc.events.ResultEvent;
import mx.messaging.*;

public function initApp():void {
     var cs:ChannelSet = new ChannelSet();
     var customChannel:Channel = new AMFChannel("my-amf", "http://localhost:8400/blazeds/messagebroker/amf");     cs.addChannel(customChannel);
     remoteObj.channelSet = cs;
public function writeToConsole():void {      remoteObj.writeToConsole(
"hello from Flash client");
      var returnedVal:String = remoteObj.setName().lastResult;     Alert.show(returnedVal);
//[Bindable]

<mx:Button label="Write To Server Console" click="writeToConsole()"/>
</mx:Form>

Java code
public
     public SimpleRemoteObject(){
          super();     }
class SimpleRemoteObject {
     public void writeToConsole(String msg) {          System.out.println("SimpleRemoteObject.write: " + msg);     }
     public String setName(){          System.
out.println("Name changed in Java");
          return "Name changed in Java";
And I have configured destination in remote-config.xml
<destination id="sro">
   <properties>
    <source>SimpleRemoteObject</source>
    <scope>application</scope>
   </properties>
</destination>
Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.

How to call a C function calling a Java Method from another C function ?

Hi everyone,
I'm just starting to learn JNI and my problem is that I don't know if it is possible to call a C function calling a Java Method (or doing anything else with JNI) from another C function.
In fact, after receiving datas in a socket made by a C function, I would like to create a class instance (and I don't know how to do it too ; ) ) and init this instance with the strings I received in the socket.
Is all that possible ?
Thank you very much for your help !

Hard to understand the question, but by most interpretations the answer is going to be yes.
You do of course understand that JNI is the "API" that sits between Java and C and that every call between the two must go through that. You can't call it directly.

How to call two RFC in a single JAVA method.

Dear all,
I just want to know that how to call two RFC in a single java method which is defined in CRM implementation file. I'm using NWDS as the customization IDE & working on ISA 7.0.

Hi Sunil,
In the Backend Implementation class, in any method you can call multiple RFCs.
It will be the same way as you do for the single RFC call.
Following syntax is for your reference.
Get the JCO connection
JCoConnection connection = getDefaultJCoConnection();
JCO.Function func = connection.getJCoFunction("ZXXXXXXX");
set the import parameters
Execute it.
connection.execute(func);
get the data from export / table parameters
Now call the second RFC
func = connection.getJCoFunction("ZYYYYYYYYYY");
set the import parameters
Execute it.
get the data from export / table parameters
close the connection
Hope this will help you.
-Chandra.
