JAX-RPC ArrayLists and Jave Beans

Can any one tell me if JAX-RPC supports an ArrayList of JavaBeans

In my experience, Apache Axis is capable of serializing and deserializing any java.util.Collection instance, provided it can serialize and deserialize the objects held by the collection. This means that a List populated with beans should cause no problems.
A word of caution though: XML serialization of objects is nowhere near as fast as the 'usual' Java serialization. This means that -if you're sending or receiving large amounts of beans per call- you might consider sending and receiving the List as attachment (ie: binary). I realize this defeats interoperability for the related web service methods, but having your users wait dozens of seconds on responses is rarely a viable alternative.

Intercepting SOAP XML message in JAX-RPC Handler and calling a diff method

Is it possible to intercept the SOAP XML message in the JAX-RPC handler and avoid the serialization and deserialization (OR avoid XML data binding)
Here is a more detail question
My web service has two methods
1. One Method which accepts Java Object (this object is mapped with a Schema
Complex Type Element in my WSDL file)
2. Second method which accept simple String type.
I want my web service client to send java object (using the first method), so that the Input gets validate in the WSDL itself (before it hits the actual web service) but once the request gets validated i want to pass that converted SOAP XML String (on the Server side using JAX-RPC handler) to the Second method.

The answer to this is that the WSDL had
elementFormDefault="qualified"
in the schema.
Changing to unqualified resulted in the desired output.
Note: The service was changed to handle both cases.

Create XML dynamically from schema and Java bean

Hi,
I'm looking for suggestions on the best approach to create an XML file programatically from a schema and Java bean.
The schema used is not fixed and may vary with each request so a dynamic way to create the XML is required.
Is there an API available that allows me to achieve this easily? Any help would be appreciated to point me in the right direction.
Thanks.

XMLBeans or JAXB should work for you.

What's the difference between using java directly in JSP and java bean

What is the difference if I use java code directly in JSP or use java bean in JSP?
Which class to use for receiving the passed parameter from html or java script? Any difference for java code and java bean in the way receiving the passed data?
How can I pass string from jsp to html or java script?

2 you have to write the class and use set and get methods
3 What do you mean when saying passing string from jsp to html??, do you mean the value you can use <%=variablename%>

Calling a webservice(JAX-RPC) from non java client ?

Hi,
I read JAX-RPC is used for accessing webservices by calling the webservice methods from a java-based client.
Is it possible to call the Webservice methods(writeen using jax-rpc) from a non-java client,who sends his request in the form of SOAP based calls?
If JAX-RPC is not the correct one to call a RPC from a non-java client,In what way i can do this?
Can anyone please clarify my doubt..,
Thanks in Advance
Rao.,

Hi Arun,
Can i write a my client program using cgi scripts?
In the JAX-RPC docs it was said that i can invoke my Webservices through my Service endpoints or using WSDL location?
If iam using a Non-java Client,it will be easier(I think) to use the WSDL file to call the Web-Service(deployed using JAX-RPC).But,the Client should be aware of that WSDL file.
I have to develop a small Application using webServices(must use XML,SOAP technologies).The user will pass some Parameters as request and the Response should be an XML(SOAP message) message.User should be able to request via browser.(http://localhost:8080/)
Can you please suggest me which technology is correct to use,so that i can use the XML,SOAP in it.
Please let me know...,
thank you once again..,
Regards
Rao.,

WLS 8.1 JAX-RPC stubs and SSL

I am part of an industry effort to assess WS interop. We have created a common
WSDL that will be implemented in WAS, .NET and WLS 8.1. As part of this effort,
we are also trying to use two-way SSL authentication. However, I have not found
a way to configure WLS 8.1 JAX-RPC Stubs (generated using clientgen utilities)
to present the client certificates. I have a tried a couple of approaches but
neither of them works with the stubs.
First, I tried using the SSLAdapter (as explained in the "Programming Web Services")
documentation. Unfortunately, the service that I am trying to invoke has only
http binding and trying to invoke it using the SSLAdapter throws an exception
complaining that SSL can't be used on non-https binding.
I tried to try another approach. In this, I tried to invoke https: URL for the
web service instead of using the Adapter. However, in this case, I am getting
a peer certificate not presented exception. Everything that I have checked in
adding a client private key and trusted certificates utilize SSLSocketFactory
(& SSLContext) or HttpsURLConnection objects.
At this point, I have ran out of ideas on how to add SSL to the generated client
stubs to tell the generated StubImpl or ServiceImpl implementations to use a different
SocketFactory or connection. There may be some other global class or property
to set these things up, but I am not aware of those. The server side SSL configuration
seems to working fine, as the requests with SSL configuration of "Request Client
certificate but don't enforce it' seems to work fine.
Any responses and suggestions are greatly appreciated.
Thanks
Raj

Ok, this seems to be a long and convoluted path to do absolutely nothing.
You submit the form.
You run a servlet that gets the parameters correctly (good), creates a SimpleBean (good) and then sets this into request attribute space under the names "user" and "pass" - (why?)
You then forward to the jsp: submit.jsp.
Submit.jsp creates a new SimpleBean, and attempts to populate it with <jsp:setProperty>. You then call the issueData method on it.
Your complaint: Rows are being created in the database which have empty string values instead of the parameters you have passed.
So, why are the values blank? Where do you think these values should be coming from?
Looking at SimpleBean we find one mistake - you have mis-named your get/set methods.
To properly follow java beans standards, you should use camel-case for your methods.
Rather than getuserName() the method should be getUserName(). getpassword() should be getPassword() etc etc.
The method getUserName() defines a property "userName" for the bean.
Once that is fixed, lets go to submit.jsp. The <jsp:setProperty> statement will try and set all properties of the bean from the request parameters.
There are no request parameters "userName" or "password" so those values don't get set in the bean, therefore it uses their default value of empty string - "".
There ARE request parameters called "user" and "pass" but because they aren't properties of the bean, they get ignored.
As a result, the values are empty string, and that is exactly what gets inserted into the database.
Ways to fix this
1 - rename your parameters on your form to be "userName" and "password" to match the bean. That way the <jsp:setProperty> tag will populate them properly.
or
2 - Call issueData() method from your servlet after you have created the SimpleBean. Better in my opinion as you then don't have any scriptlet code on a JSP page.

Forms 6i and Java Bean

Hi
I need to establish communication between my forms and java code.
i have made a java bean and set the implementation class path(i.e the package path (oracle.forms.demo for the bean class)) in the form item.
I want to know where exactly should put the java code or do i have to make modification in any of the environment variables to allow the forms to acces the java code.
what exactly is a java class and do i need to have a wrapper class also to implement the java bean.
please respond fast as i need this info urgently...any small info might prove fruitful
Thanks

Hello,
All you have to do is to copy the .jar file that contains the Java class(es) in the <devsuite>/forms/java/ directory, configur the <devsuite>/forms/server/formsweb.cfg file to add this jar file to the archive_jini tag to indicate where Forms have to load the classes:
archive_jini=frmall_jinit.jar,...,my_jar_file.jar
Then after, you have 2 possibilities:
- the bean does not have any "screen" representation so you can just handle its functions with the Forms internal FBean package functions (no need to put implementation class on the bean area item property)
- it has a screen representation, so you put its implementation class like you did, and you set its properties with the Set_Custom_Property() built-in and get its properties with the Get_Custom_Property() built-in.

New to Jsp. Jsp and java bean not running

hi
i have created a simple jsp file and using a java bean. but it is showing errors. my file directory structure in tomcat4.1 is:
aptechsamples:
index.jsp
WEB-INF/classes:
myPackage:
Counter.class
i have no web.xml file i dont know how to use it or not. i need it or not.
the index.jsp file:<html>
<head><title> A Simple JSP Bean </title></head>
<body>
<%@ page language ="java" %>
<%@ page import ="mypackage.Counter" %>
<jsp:useBean id="id_counter" scope="session" class ="Counter"/>
<jsp:setProperty name="id_counter" property="count" param="count" />
<jsp:getProperty name="id_counter" property="count" />
</body>
</html>the Counter.java file is: package mypackage;
public class Counter{
     String msg;
     public Counter(){
          msg = "Hello World";
     public String getCount(){
          return msg;
     public void setCount(String c){
          msg = c;
}please help me and tellme what the hell is wrong with it or me. im getting an error:
exception
org.apache.jasper.JasperException: Cannot create bean of class Counter

Java is already telling you what is wrong: it cannot create an instance of your Counter class. The reason being: it can't find it.
What do you mean by "myPackage"? Before you can use any class in your JSP's or servlets, they MUST be stored in a package. If you don't know what that is, I highly suggest you lookup "java package" and "java classpath" using google.
Let's say your Counter class is in a package mypackage (so it starts with the line package mypackage;). Then you have to store the .class file as:
WEB-INF/classes/mypackage/Counter.class
If done correctly, the error message should disappear.

How to include PJC and Java Beans in forms

I have tried a lot to include java codes in my forms ..So I decide to start with ProgressBarPJC(cause it is tested and provided with demo) but I could not set implementation class of java bean object to
oracle.forms.demos.ProgressBarPJC it does not accept it but it accept ProgressBar instead of ProgressBarPJC. I don't know why? I have made changes in Forms90_builder_classpath to access f90all.jar and progressbar.jar. I have Progressbar.class and progressbarpjc.classs both but i don't know how to set implementation class to ProgressBarPJC.
don't you think there is lots of configuration and path setting to use any JPC or Jar in forms? I am totally confused with this integration.
Please solve this matter
Thanking you,
Neeraj

and even more information samples and step by step instructions are on the Java spotligh on the Forms Upgrade Center : http://otn.oracle.com/formsupgrade

Need advice about web services and Java beans

Hi
I am very new to web services and to Java beans as well.
I am trying to understand if and how a web service can use functionality I have in a Java bean. I couldn't find any documentation I can use.
For example:
InitialContext ic = new InitialContext();
Adder adder = (Adder) ic.lookup("ejb/AdderJNDI");In a EJB client project (I'm working with Eclipse) if I add the EJB project to the build path, the Adder interface is recognized.
Theoritacally I thought I can do the same in a web service server project, but the Adder interface is not recognized.
Is there something I can read to understand how I need to use the EJB or implement the web service?
Many thanks
Sigal

Okay....I think I made some errors with the original scenario:
It basically comes down to this....I think. OCS Calendar has a set of Java classes and methods that provide an abstraction for their web services interface. I know how to create something to use these classes using an IDE like JDeveloper, but I'm not sure how that would work with HTML DB.
I've noticed that the SQL Workshop has a place for Java sources and classes, and I've heard mentions of PL/SQL wrapping. Is there a way to import classes into an HTML DB workspace, wrap 'em up, and access them via PL/SQL?
Thanks again,
Jonathan

First use of jsp and java bean and "Unable to compile class for JSP" error

Hi,
I am trying to create my first jsp + java bean and I get a basic error (but I have no clue what it depends on exactly). Tomcat seems to cannot find my class file in the path. Maybe it is because I did not create a web.xml file. Did I forgot to put a line in my jsp file to import my bean?
Thank you very much for your help.
Here is my error:
An error occurred at line: 2 in the jsp file: /login.jsp
Generated servlet error:

CMBConnect test = null;
I only have this in my directory:
test/login.jsp
test/WEB-INF/classes/CMBConnect.java
test/WEB-INF/classes/CMBConnect.class
Do I need to declare another directory in classes to put my class file in it and package my bean differently?
Here is my login.jsp:
<%@ page errorPage="error.jsp" %>
<jsp:useBean id="test" type="CMBConnect" scope="session" />

public class CMBConnect
public CMBConnect () { }
public String openConnection(String id, String password) {

try {
Connection con = null;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
con = DriverManager.getConnection("jdbc:oracle:thin:@myserver.abc.com:1521:TEST", id, password);
if(con.isClosed())
returnText = "Cannot connect to Oracle server using TCP/IP...";
else

Memory and java beans

i have servlet that creates a bean that holds some data from a table.
Purpose: not to hit DB2 everytime to build some drop downs on jsp.
We just wanted to have a bean in the memory and access it whenever we need it.
Now, my concern is server memory.
Can someone tell me how does java data beans effect memory?
My java bean holds only plain text from the table.
I think there are over 1300 records. is it worth doing this?
Is there a guide that tells me for how many rows how many MB of ram is used?
thanks
nn

Well you need not worry much about memory as this will be taken care by the Container i.e. EJB Server in general
The EJB Server will serialize the object in the file if it is not used for a certain period of time and again deserialize when the file is used
Bye for now

Popup menus in Forms 10g and Java Bean

Hi all.
What class in Java corresponds with popup menus(not in menu module) ?
I know that oracle.ewt.lwAWT.lwMenu.LWPopupMenu is corresponds with MenuBar's submenu. I can find Buttons, Text Fields, Menu and other components in my Form-Applet, but I don't know how to find popup menus in forms through Java Bean...

Hello François,
I have created a java bean that dynamically creates a popup by left-clicking on the bean.
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item' ) ;
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_SEPARATOR', '' ) ;
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item one' ) ;
          Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item two' ) ;
My problem is the layout. I want to simulate a button. I can't put the bean transparent over a button and I can't simulate a button with the bean.
How can I add the popup functionality to a button and not only to the bean? Or any other workaround?
Regards Pedro.
