How to implement a java application in Portal

Hello,
I was asked if it is possible to implement a java (not a web application / not java web dynpro) to implement into the portal. Is this possible with something like the java web start? Is someone using something like that in the real world?
Thanks a lot,
Vanessa

Hi Vanessa.
Yes, it is possible to integrate Java applets into portal. Have a look at XML Form Buider or SAP Management console (http://portalhost.domain:5xx13).
Best regards,

How to make a Java application that will change the client box's IP address

HI how to make a Java application( that application would be run on the client ) that will change the client box's IP address ( IP address of itself )

If you can do that through the command line, then use Runtime.getRuntime().exec(...) to execute your command.

How to schedule a java application via Windows Scheduler

I can't figure out how to schedule a java application using the Windows Scheduler. Do I schedule the java application with the .class file as a parameter? How do I pass arguments to it?
To execute FileCopy.class, my best guess was:
Start | Control Panel | Performance and Maintenance | Scheduled
Tasks | Add Scheduled Task | Browse | Program Files | Java |
jre1.5.0_06 | ... Advanced Properties
Under the Task tab:
Run: "C:\Program Files\Java\jre1.5.0_06\bin\java.exe"
Start In: "MyDocuments\Eclipse_Workspace\Java_File_Copy
FileCopy"
This does not work. How do I schedule the FileCopy.class java application, and how can I pass arguments to it? Can this be done without specifying a password?
TIA,
John

Suppose that your class is FileCopy (has no package name) and is located under MyDocuments\Eclipse_Workspace\Java_File_Copy folder, then you should have:
Run: "C:\Program Files\Java\jre1.5.0_06\bin\java.exe" FileCopy
Start In: "MyDocuments\Eclipse_Workspace\Java_File_Copy"
And yes you must provide a user password to execute the task.
Best way to do this is to create a special user (with password) for executing this task.

Trying to do the simple HelloWorld java application for portal

Hi:
i've been trying to do the simple java application HelloWorld so that i can get a view of how will it be to integrate a pure java application that we have in a later step. The fact is that i've been following "how to build a java portlet" and "packaging and deploying your provider" documents.
i've taken the code from that document:
public class HelloWorldApp {
public static void main (string[] args){
//Display "Hello World!"
System.out.println("Hello World!");
That's my java code. (in fact i want to do this as a trial, 'cause later i will
do the same with a java application of our own).
So i compiled it, taken the .class, jar it and packaged it as told in the
second document.
I've deployed it in OC4J_portal and when i try to access the URL i get an
error:

does anybody know how to solve this problem?
Thx.
Regards. Urko.

Hi Urko,
Such an application as you have quoted will not have much luck as a Portlet - the code you supplied simply writes "Hello World" to standard out!
Think of a portlet more like a servlet - you have an output stream to write to which, under the covers, is wired back up to the Portal Server which assembles the content into the page seen in the browser.
Take a look at the extensive range of sample Java Portlets available with the PDK download.
Anyway, from the stack trace it looks like you're using JavaRenderer. JavaRenderer invokes an arbitrarily named method on an arbitrary class **provided** that method takes a single argument of type PortletRenderRequest. So you would need something like:-
public class MyApp
// A bunch of app-specific code.
public void renderPortlet(PortletRenderRequest pr)
PrintWriter out = pr.getWriter();
out.println("<b>Hello World</b>");
Then, the relevant provider.xml section would look something like this....
<showPage class="oracle.portal.provider.v2.render.http.JavaRenderer>
<className>MyApp</className>
<renderMethod>renderPortlet</renderMethod>
</showPage>
Hope this helps.....

How to deploy my Java application?

Have a proxy server running as a plain vanilla Java application from the DOS command line in Windows. Would like to run it 'properly' on a (web) server. Have got Apache and Tomcat installed but I don't know how to adapt my application to run in that environment. The proxy server maintains a socket connection from another backend machine and pushes information from there to a client that connects to the proxy server.

Well what's confusing is your use of "maintains", in "maintains a socket channel". That's largely counter to the design of the HTTP protocol. So I can't tell if you're using HTTP incorrectly or just describing it counter-intuitively.
If you're opening a socket from the client and keeping it open indefinitely to maintain a kind of session, then you're not really using HTTP right and you can just drop that.
If you really are using a series of HTTP connections, then Apache/Tomcat would be a fine thing.
If all you're doing is an ordinary proxy server, then actually Apache can handle that all by itself with no java code at all.
If your code is acting as a real HTTP server, then removing the web server parts, letting Apache handle that, and using Tomcat as a servlet environment would be very good. You'd be implementing only the business logic, not the standard plumbing stuff.
Have you ever written any servlets or other J2EE stuff?

Is it possible to cal web dynpro java application using portal application?

Hi,
is it possible to cal web dynpro java application using j2ee portal application?
If possible, how can it be done the parameter mapping over context area?
Regards.

you can just append parameter to the url as usual.
you will write some code in the controller to get the parameters and set them to the context.

How to execute a java application once the server starts

I have created a java application which executes correctly. I want this application to execute everytime I start my server. I have modified my web.xml as shown below
<servlet>
<servlet-name>SendEmail</servlet-name>
<servlet-class>
com.allcorp.alliance.tdocs.servlets.SendEmail</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
<load-on-startup>1</load-on-startup>
</init-param>
</servlet>
I have extended the class with HttpServlet. When I start the server, I get the message saying the class is being initializing but it does not execute. I want the application to execute. Any idea what I need to do.

Implement ServletContextListener and run the appplication on creation of the ServletContext.Well i understand implementation of ServletContextListener and by overiding contextInitialized(ServletContextEvent se) accordingly can solve the problem.
but you need to consider two cases here first
1).ServletContextListener is not supported by all container especially the minor onces which does not support Servlet 2.3 specification.
2).OP does not have any idea of how to use a Servlet first if you can see he had written his intialization code in the main method.Now how can you expect him to create a listener..... :)
I hope there are no hard issues on what i said this time.
*@OP*
My friend the bad news is that you need to spend bit of time learning about servlets.U'd not be writing intialization code inside a main rather you'd be doing it inside public void init(ServletConfig config) method.
by making <load-on-startup><!--value</load-on-startup> in web.xml enables Servlet container to call init method at the time of deployment of the web application else where it'd call the init method whenever servlet encounters first request from a client.

How do i run java application on 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

You can try using Macromedia JRUN version 4. Any of the version will have an ISAPI filter which you can add to the IIS site of your JSP/Servlet.
The JRUN ISAPI filter will establish connection to the JRUN proxy listener on a port. This port is called proxy listener port. Basically once you install the ISAPI, it will have config file called jrun.ini
Check for the ProxyPort entry in jrun.ini (or something like this - sorry, I can't remember the exact entry). It should match to the proxy listener port where of the server where your JSP/Servlet is intalled.
Good luck !

Hi
Check this article on JGuru. It explains how to use Tomcat together with IIS.

If you also need to use EJB's you probably also want to have a JBoss installed - check www.jboss.org

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:
http://jakarta.apache.org/tomcat/tomcat-3.3-doc/tomcat-iis-howto.html
Shoud be the same for version 4.1

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by [email protected]:
Henrik, the Java importer lets you call Java classes on the app server side - I think what Ali is trying to do is integrate on the client side.
If you want to add your own button then if you extend the standard Forms button in Java and then use this class name in the implementation class property then the Java for your button will be used instead of the standard Forms button. And since it has extended the basic Forms button it has all the standard button functionality.
There is a white paper on OTN about this and we have created a new white paper which will be out in a couple of months (I think).

How to call a java application in a jar which is in a war file of a ear ?

So sorry to cross post, but no response in other topics.....
Please help!
I have a Ear file which contains a war file.
xx.ear/META-INF
xx.ear/YY.war
and the YY.war has the following structure:
YY.war/META-INF
YY.war/WEB-INF
YY.war/WEB-INF/classes
YY.war/WEB-INF/classes/com/
YY.war/WEB-INF/classes/com/mycompany/
YY.war/WEB-INF/classes/com/mycompany/MyClass.class
MyClass.class is a java application which has a main method.
how can I call this MyClass applicaiton from the xx.ear??
java -???? com.mycompany.MyClass ??
Please help because I have a Unix cron job need to access this class externally outside AppServer. Thx!!

an ear file is a standard jar with a different extension. You may
be able to get away with just adding a manifest file to it that
specifies the main class (make it an executable jar with a different
extension).
I don't know if this will handle the nested war file though. It may.
