Plugin-friendly Java applications

Hi all,
I have been trying to research making a web application that is mostly Java-driven that will be able to accept plug-ins that are written for it. Specifically it is written from appfuse, if that is of further help. Has anyone done something similar to this in Java and have any tips or helpful online resources on the subject? I'm having a really tough time finding assistance with this online, considering most sites are either advertising plug-ins or talking about making the plug-ins themselves for application X...not making application X :) Any assistance is greatly appreciated.
Thanks

Look at the Bean Object.

Java application problem

I am using JDK1.4 and working on Windows Xp.
I have written a code for application in java as follows:
import javax.swing.*;
public class sample
JPanel panel;
static JFrame frame;
JButton but;
public sample()
frame=new JFrame("frame");
panel=new JPanel();
frame.getContentPane().add(panel);
but=new JButton("click");
panel.add(but);
public static void main(String args[])
sample s=new sample();
frame.setSize(300,300);
frame.setVisible(true);
on executing program application window has appeared and it ran properly.
Then I closed that application window.But after that in command prompt window curser was just blinking and it was not allow to enter also.
I have tried pressing CTRL+C also.But situation in command prompt was same i.e curser in command prompt was just blinking.
Then I closed cmd window ;but one error has occured saying that cmd window can not close .
My friend has told me that she is also having windows xp and JDK1.4 ; ctrl+c is working properly in her command prompt.She has written the above same code in her computer and it executes properly.
Even though she has not written following statement:
"frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);"
when she exits from application window ,her cmd window gave same problem of only blinking curser.But when she press CTRL+C ; her command prompt starts responding by giving root.But my command prompt is not giving
positive responce to "ctrl+c" when I am exiting java application.
Is it possible to solve this problem without giving statement
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); ?
Why my command prompt is not responding to CTRL+c?
How can I tackle this problem ?
Is there any other key which can be used in command prompt of Windows Xp?

Is it possible to solve this problem without giving
statement
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
?this is because Swing have started some non-daemon helper threads for its internal purposes and the default close operation for frame is just HIDE_ON_CLOSE. So, the system will not exit because those non-daemon thread still not terminated.
What is the problems setting the default close operation to JFrame.EXIT_ON_CLOSE ?

How do i run java application in IIS

Hi,
Can I run java application on IIS(Internet information Server)?
If yes, How do i do that?
My java application contains JSP,Servlets and EJB.
To run java application on IIS which plug in should i use.
Can anybody help me This is urgent...........
Thanx

Can i use EJB components in it?Yes, you can use EJB components. IIS uses Tomcat as a plugin and Tomcats feeds IIS with HTML code. Tomcat performes all the JAVA work including EJB. This links shows you how to install it:

Shoud be the same for version 4.1

How to disable my java application after a few days

I have a java application as a MyApplication.jar file. On clicking this .jar my application starts. I want to distribute this jar to my friends so that they can run the application and use it. However, I want my application to run only for a few days. The jar should become unusable after say 10 days and no one (including the people holding the jar) should be able to execute it.

>
...I want to distribute this jar to my friends so that they can run the application and use it. However, I want my application to run only for a few days. >Just a wild guess. You don't have many friends*, do you?
In any case, the usual way to approach this task is to write a key to the system that contains the first date the software was run, then check it each subsequent launch. If the 'first date' + 'allowable days' is before 'today', pop a message telling the user that the software has expired.
As to how/where to store this information..
You might use the Properties class to read/write the date property.
Problems with this approach are
a) Users adjusting their system clock to a previous date to get software to work again.
b) Users finding and deleting the file containing the 'first date' property.
c) Users leaving the software running for 173 consecutive days.
d) * Users hating the software so much that they come and burn your house down.
( That last one is the real worry. ;)

Java application -- webservice --- XI ( RFC ) ?

Hi friends ,
 My scenario is like I want via web service I need to pass request to RFC and get the response back . This calling webservice is external java application .
 Can u please tell me What steps i have to do in XI ?
 I have to do synchronous Interface between RFC and webservice right ?
 First I have done this scenario by designing IR and in Configuration I have used SOAP Sender and RFC Receiver adapter . Using Synchronous Interface
 Using Tools -- > Define WebService . I have Defined that as WebService . I has creatd the WSDL File for me.
 I have given the SWDL file and the URL like the following
http://xidev:8021/XISOAPAdapter/MessageServlet?channel=:BS_DISTANCE_CHECK_SOAP:CC_DistanceCheck_SOAP_Sender
 If i copy and paste this URL in my pc .It is showing the Message Servlet Status OK . and some informations also it is giving .
 But the java guys try to use this URL in their web service calling module it is not working .
 The way what i have done is corret ? or something i have to do ?
 What input i have to give to Java Guys to call the webservice ?
 Can you please give your suggestions asap
Best Regards .,.
V.Rangarajan

Hi Bhavesh ,
 Thanks for your reply.
 Then that URL and WSDL File Which i have given to the Java guys is enough ?
 I have one doubt .I don't know much about the webservices .
 Don't we need SOAP Receiver Adapter for this ?
 How the external application will get back the result ?
Best Regards .,

Error when embedding the plugin inside java

I have IE wrapped inside java, and when IE loads a page with java, I get the error message "Attachment to a running Virtual Machine failed." I guess the plugin gets confused by the allready running VM.
Do I need to supply some hooks for the plugin?
My code is a http://nothome.com/IEcanvas/

My organization is also trying to embed IE 6.0 inside of a Java application using the IECanvas code, http://www.nothome.com/IECanvas/. That code was derived from work done at The Code Project, http://www.codeproject.com/java/javacom.asp.
We are attempting to use the Java 1.4 release candidate with this code. Everything seems to work well, until IE attempts to load a Web page that has an imbedded Java applet that requires the Java Plugin. We have insured that IE is calling the exact same version of Java, version 1.4, when loading the plugin. Unfortunately, when the Java plugin starts loading, the error "Attachment to a running Virtual Machine failed" is presented in a dialog box titled "Java(TM) Plug-in 1.4 Fatal Error".
After this IE asks if the user wishes to install the Java 1.4 plugin. Essentially, no Java 2 applets will work in IE once it is embedded in our Java application.
I have done some research, and discovered that it should be possible to run more than one instance of the Java Virtual Machine in the same process space. I would like it if someone knows how to force the Java plugin to start a new Virtual Machine instance instead of trying to connect the the already running instance in the encompassing Java application.
Thanks!

Can we call a webservice using standalone java application ?

Hi friends,
 Can we call configurd webservice in xi , using standalone java application by just giving url of webservice ?
 OR
 Only by means of WEBDynapro we can call ?
 Can you please tell me the answer for this .
Regards .,
V.Rangarajan

HI Ranga Rajan
well, If at all if you have webservice...you can import that werbserivce as External definition in to IR.
How to import:
1) Go to IR and and move to your requied component and there you can see the option called imported objects...select on imported objects where you can give the name and you can select the webservices which you want to use it.
2) Hope you are aware of that a werbservice will have the request and response.
3) Create the mapping program accroding to your requirement.
Go through blogs of Bhavesh and Naveen which talks about calling webservice in a specific condition:
Webservice Calls From a User Defined Function - /people/bhavesh.kantilal/blog/2006/11/20/webservice-calls-from-a-user-defined-function
Consuming/Calling webservices from DataBases - /people/sap.user72/blog/2005/10/20/consumingcalling-webservices-from-databases

Can we wrap a RFC as webservice and use from external java application ?

Hi Friends ,
 Our scenario is call a webservice ( wrapped form of RFC) from a external java application which will pass the input to that webservice and get back the result .
 How XI will play a role here ?
 Can we wrap a rfc as web service ?
 Any blogs for that ?
 Can you please give a brief details about this ?
 Expecting yoour asap
Best Regards .,
V.Rangarajan

Hi
Can we wrap a rfc as web service ?
Yes.
To use the SAP Web AS 6.40 you need to build a wrapper in the 6.40 system. This is a remote function call (RFC) enabled function module with the same interface or a similar interface that internally calls the required RFC-enabled function module in the old 4.6x system via RFC. The wrapper then can be exposed to the outside world as a Web service. Another option is to use the Integration Broker capabilities for calling Web services in an older system.
How XI will play a role here ?
XI will pass the input to the external java application and get back the result to the webservice

How connect an HTML page to a running Java Application?

Hi,
Exists a way to connect an HTML page to a running Java Application?
the idea is, If we use SWT, the Browser widget have an instance of IE/Firefox attached to it, and we load local HTML pages inside, then i wish to have a way to bridge Java Application from HTML page. Then with that we can do follow JScript:
var javaApp = document.getJavaApplication(); //here is the trick
//below is like we do today with applets
var person = container.create("myapp.Person");
person.setName("Test");
container.save(person);its great if we can Have an attribute for object tag or anything to conect HTML page to Java Application.

I think that the better idea is to create a new mime type for that, maybe "application/x-java-connect-to-local-jvm", and use embed tag, to connect via plugin to a running JavaApp
example:
<embed type="application/x-java-connect-to-local-jvm" width="20" height="20" mainClass="mypackage.AppName"> 
<script>
var javaApp = document.embeds[0];
function createPerson()
var person = javaApp.getNew("mypackage.Person");
person.setName("test");
javaApp.save(person);
}The width and height, isnt necessary, but the view can be used to show red if connection failed and green for sucessfull connections, or maybe embed tag can have src to images for sucessfull and unsucessfull states.
That's the idea, there is a way to extend Java Plugin to achieve that?
any tip or idea or to achieve that, are welcome.
Thanks

iViews used for application integration have a property called (technical name: LAF_Switch) like Send portal theme. This parameter defines if the portal will send to portal's style sheet definition. If so, the WDJ application will decide on some rules if or not to use the portal theme.
[The SAP Note 1000889|https://service.sap.com/sap/support/notes/1000889] explains how a WD application decides whether to apply the portal theme or not. The note also gives you some hints to find out why the portal theme isn't getting applied.
