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:

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 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).

How to invoce remote none-java application in Portal Server

Hi all
We have a project that try to use SUN portal server to call remote coldfusion application, according to the server guide I just find the remote portlet can be invocate. Any one had the experience on that.
Thanks
Rosso

The iFrame Provider is provided out of the box with the Sun Portal. You can just use psconsole to add a new channel to a tab. Select "Provider" for the type and then select iFrame for the Provider. You can enter a URL property that points to site you want to appear in the iFrame. There are other useful properties that control scrolling behavior and the height/width of the channel.

Hi Sarang,
It seems you are following the two basic pre-req.
It may be now possible that your browser might be not allowing cookies. Which browser are u using? Version etc?
Right now u can try two things:
1) When you have logged into portal, type the following command in the adress bar "javascript:alert(document.cookie)". This will give u a popup displaying the cookies formed when logged into portal
2) Use some software like HTTPWatch or ieHeaders and find out the details. It will give you all the cookie details etc.
You should be able to see the JSESSIONID, MYSAPSSO2 cookies...Let me know the result of above..

Java applications on EP server

Hi EP Experts,
I would like to know following things.
1. How do I migrate Java applications on Portal server? (one way using JAVA PDK)
2. What are the different problems that are faced during migration of Java code to EP server
3. Do we need to import specific libraries that are used specific for Java applications and are not available with WAS/EP?
If any one has similar migration experience please share the problems that are faced and if possible solutions you got for any.
Thank you,

How to get Portal user from a standalone Java application

Hi,
I have a standalone Java application from where I need to fetch the Portal User Information like userid and email id.
I am using the below line of code
iUser = UMFactory.getUserFactory().getUserByLogonID("e017939");
I have included the jar file com.sap.security.api , But it was giving me the below exception
java.lang.NoClassDefFoundError: com/sap/tc/logging/Location
     at com.sap.security.api.UMFactory.<clinit>(UMFactory.java:55)
     at com.am.wcas.java.mailscheduler.kmaccess.FetchDataFromKM.getiUser(FetchDataFromKM.java:29)
     at com.am.ScheduleEmails.main(ScheduleEmails.java:89)
and I am getting a pop Up message from the Java Virtual Machine Launcher, saying a Fatal Exception has occured and the Program will exit.
Then I went throught he SDN threads and they asked me to include the
logging.jar and com.sap.security.perm.api .
I Included them, then also, it is giving me Exception
java.lang.NoClassDefFoundError: com/sap/engine/lib/logging/LoggingHelper
     at com.sap.security.api.UMFactory.<clinit>(UMFactory.java:56)
     at com.am.FetchKMData.main(FetchKMData.java:30)
Exception in thread "main"
and I am getting a pop Up message from the Java Virtual Machine Launcher, saying a Fatal Exception has occured and the Program will exit.
Kindly let me know if it is possible to access the User info using UMFactory in a standalone Java application. If yes kindly let me know where i am going wrong.
Regards,
Shilpa B.V

Hi Shilpa,
1. Check that you have added com.sap.security.api within the Your Project>Libraries folder (under navigation tab) and also added jars in the build path of the Your Project under project>properties>Build Path.
2. In case you have a DC instead of Web Dynpro Project then you have to add the com.sap.security.api under Your DC>Used DCs and have compile time and runtime dependency added.
Here java.lang.NoClassDefFoundError is caused basically due to only build time dependency added and reference to the jar missing at runtime. Rest the code to retrieve the current user id using UME API and getUserByLogOnID("....") method with/without portal environment would not be an issue at all.

Can we control the top level navigation in portal from a java application

Hello,
I am having a scenario where User logged in to portal and assigned with 2 roles (HOME , ISA(Java application)). When user opened a form in ISA (Java application) and tried to enter the data in form and moved to another tab (e.g. HOME) in top level navigation.
When user come back to ISA (Java application) TAB , we show the page where he left earlier. I would like to know if user click any other TAB in top level navigation (Role assigned to him) while working on a page in ISA(Java application) is there any way we can catch that event before he leaves from ISA (Java application JSP page) to other TAB?
How can we control the top level navigation events in the portal from a java application .Since Top level navigation is seperate par file.
Thanks,
RN

Dear Rajesh,
Top Level and detailed navigation values comes with iteration in the respective par file.
Please check the par file and based on the value (i.e tab name) selected, you can write your code.

How to deploy the custom java application for self regaistration in portal?

hi,
I have created a custom java application in NWDS for Self Registration of new users.I am working on EP 7.02 and the standard self registration application is a Web dynpro java application.
How can i deploy my custom java application built as a par file in place of the Web dynpro java application?
Thanks,

Hi Amarys,
If you have developed the PAR file in NWDS then you can deploy the PAR in the server with NWDS ( [Check Required Settings |NWDS 7.0 does not deploy PAR;) or in server directly (system administrator > support >> portal runtime >> administration console)

Embedding java based application in portal

hi ,
I want to embedd a java based application..Iam giving the pageURL in provider file..will it work r any problem..
i want to display that application as portlet.is mentioning page url is enough..that is tomcat..
Second way:if i copy all jsps and source files to htdocs and create a war file and ear file..will it works..
how to mention in provider.xml file to show this application in portal.
is there any specific way..
plz mail me
regards,

Our expirience with these types of applications is that you will need to integrate your jsp files (to some degree) into Oracle's jpdk framework, which essentially means some of the functionality of your jsp files may not work properly unless you switch to use many of JSP files with the JPDK api (i.e. custom tags and custom api calls so that the portal can render your application as a java portlet provider).
I think there is also a way that you can deploy your web application in oc4j and possibly use the web clipping portlet to show this java based application, however, I am not familiar with this, and you should probably ask Oracle Support for more information

Jack
