Deploing/Developing Java portlet application

How are you developing java portles?
I'm using IDEA + ANT + NW04 Sneak Preview SP11
But after several redeploing of application I'm always getting errors
1. admin user locked (Only reinstall was helped)
2. dispatcher can't start
Has anybody the same problem? What is your enviroment?
Is your NW installation working stable?

I use Netweaver Developer Studio.

I don't. For the moment it seems too complicated. I follow the MVC pattern when the application is big and try to look at the code of successful projects.

Which is the best and user freindly IDE for developing Java GUI application

Please advice me if there is any good IDE for developing all kind of Java applications.
I m confused about which IDE to use.
I have Searched on Net also. and most of the answers i found was for JBuilder and JBoss.
But cant confirm until u guys suggest me.
Because i think this is the best place to ask questions about java.
Please advice

If you're developing JSPs and Servlets....
I've found that using Eclipse (which is free) coupled with the MyEclipse plug-in (an advanced J2EE specific plug-in which costs $29.99USD/year) was the best for me. I've tried several free J2EE Eclipse plug-ins, didn't like them. Wasn't a big fan of NetBeans either, but I liked it tons better than the other Eclipse plug-ins.
Therefore, IMHO for free I'd go with NetBeans, for a small fee I'd go with Eclipse/MyEclipse plug-in.
If you are new to J2EE but not to Java, you may want to consider going straight to JSF and Sun's Java Studio Creator. This is not free, but the fee is one-time and development is (mostly) visual using Java Studio Creator.

You can develop java portlet (JSR 168) in current IDE .
You need to have portlet-api-1.0.jar to compile the portlet.Start with few jsp's only & required DAO , BO , VO can be called thro' portlet. You need to have portlet.xml in WEB-INF folder . This developed portal application can be imported to weblogic workshop . But you need to have ConverterTool (which converts Normal Portal Application into weblogic portal application). ConverterTool will have preparePortletsClasses.jar , which does this for you.Then while importing this application in workshop , workshop will add workshop specific files into your portal web application .
Here normally jsp , DAO , BO , VO will remail as it is .
Hope this could help you .

Building a simple java portlet

Hi:
i have a java application with some forms, textareas, checkboxes, etc. i need to put this application into a portal page. do i have to rewrite all the code? what is the structure of a java portlet application? i mean, main function, renderBody, etc. Anybody can give the most simple full example of a java application portlet?
Thx.
Regards. Urko.

Hi Erik,
Thanks for your help. I found the answer. The servlet 2.3 web application version must be used instead of version 2.4 when building the application.
Thanks Erik

Deploying Jave portlet on Oracle Application Server 10g

I have installed Oracle 10g Application server, donwloaded and installed JDevleoper 9.0.5.1 and the latest Java Portal Development and as well as the JDeveloper portlet-addin. Now, I followed the instructions from the http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/BUILD.JSR168.PORTLETS.USING.JAVA.PORTLET.WIZARD.9IJDEVELOPER.HTML
On using JDeveloper addin wizrd to create a java portlet and so far so good. However, I am stuff on the last bit on deployment. It document says "# Now use the URL provided in the log page at the bottom of JDeveloper to get part of your URL (e.g. http://myserver.uk.oracle.com:8888/my-portlet) and complete the URL.
http://myserver.uk.oracle.com:8888/my-portlet/portlets?WSDL
Now use this URL to register your portlet with OracleAS Portal.
But when i deploy my application (just a test thing), from the deployment tab I get:

My question is, HOW DO I ACCESS the deployed application, since it didn't specify the URL where it's deployed????
Many thanks
P/S
I have tried:
http://{myserver}:8888/{my-portlet}/portlets?WSDL but that doesn't work

Hi FormsEleven,
When you say you can do this or you have done for demo then considering following directory structure if I have two forms having common form names how it will be resolved?
Or how the url to access these forms will be?
As shown in the following structure consider we have Form1 in sub directory1 as well as in sub-directory2 then how the link to access these forms will be?
- Hosting Directory (formsweb.cfg entry)
- Sub Directory1
      - Form1
      - Form2
- Sub Directory2
      - Form1
      - Form4
- Sub Directory3
      - Form5
      - Form6

Java Portlet (JSR 168) development with Portal

Hello,
We have been trying to dive back into Portal development lately. The release of 9.0.4 with support for standards-based portlets has convinced us to begin looking at 9iAS Portal as a practical portal product. We have a development environment setup with a workin 9.0.4 portal.
Digging through the available docs on the portal studio site, I have come across a couple documents alluding to the installation of a portlet-container. Now, I have already downloaded the JSR 168 framework files. It seems that a good portion of this 'portlet container' consists of these files.
The problem is that the documentation that is available is nothing more than a step by step set of instructions for setting up an OC4J instance with this 'portlet container', configuring an Oracle database for portlet customizations, and deploying a sample ear into the OC4J instance.
This does nothing for me.
What I want is documentation that indicates the requirements necessary to make a JSR-168 compliant portlet (even a 'hello world') exposed through portal with the least amount of effort, and with no references to proprietary tools. I would like to see instructions that are tailored towards a generic J2EE provider, not an OC4J one. I already have a very functional set of tools that should be able to accomodate a JSR-168 producer. We have had many problems with OC4J leading us to try to avoid it at all costs.
Any ideas?
Thanks!
-Sean

Hello
I am probably not clear.
In the OracleAS Portal architecture Java portlet are remote from the portal middle tier.
In the non standard world (JPDK Portlet), the Portal Middlet tier use SOAP over HTTP to call the portlets.
In the Standard world (JSR-168), the Portal Middle Tier will use WSRP (Web Service Remote Portlet) to call the portlets. When you use the Oracle JSR-168 container inside OC4J, these portlets are automatically accessible over remotely using WSRP.
So, as you can see the Portal Middle Tier needs to support WSRP to be able to use JSR-168 portlet. And OracleAS 10g 904 does not currently support WSRP registration. It is why we have the "OracleAS Portal Verification Service for WSRP", to allow you to test your portlet.
To be able to use JSR-168 (with WSRP) portlet on you internal Portal you'll have to install the OracleAS Portal Standard Developer Preview that will be available soon.
Hope that clarify my previous statements.

Developing Java Applications for Windows CE

Hello,
I hope this sub forum is right. So I must develop a Java Application for Windows CE. I read something about J2ME, but I think this is only for Mobilephone and Windows CE supports AWT. So I tried just some simple forms with J2ME.
Can anybody tell me how I develop java Applications for Windows CE? Can I use Eclipse or must I use another IDE?
Realy I developed Swing 5-6 Month but I have no idea how I develop Java Applications for Windows CE.
Thanks a lot for helping...

Not much there, but apparently people are trying to hack it together using JavaFX 2 already. I believe I read an article where Oracle itself had given a presentation about a JavaFX2 app on an iPhone; I believe the gist of it is that they want to make it so you can bundle the Java runtime with your application, which makes it legal to sell a Java application through the appstore.

How to create a Portlet application in OPM 10.4

Hello,
We would like to create a portlet application. The purpose of creation of such application is to embedded this in the portal.
Can we get the pointer on this please?

The actual interview portlet is found in the zip you download for Oracle Policy Automation runtime components for Java (Oracle Policy Automation Downloads on OTN).
Any basic rulebase will work inside the portlet. The SocialServicesScreening example rulebase has both portlet and non-portlet projects. The rules and data model are the same in both projects but these projects contain different summary screens because portlets impose a restriction on the use of relative URLs to reference static resources. See the explanatory note in the "Change the layout or appearance of interview screens" topic of the OPM User's Guide (http://docs.oracle.com/html/E48373_01/toc.htm#Interviews%20and%20flows/Change_layout_or_app_of_interview_screens.htm?Highlight=Portlet)
The OPA Developer Guide contains an entire section on the Interview Portlet - see the topic "The Interview Portlet" (http://docs.oracle.com/html/E48376_01/toc.htm#Interviews/The_Interview_Portlet.htm)

Getting Error when trying to deploy Portlet Application on WebLogic Server

Hi,
We have a WebLogic server installed on a Windows machine. We created a new Domain, extended it with ADF Runtime and with Web Center Framework. It created three servers for us along with the already existing AdminServer, WLS_Portlet, WLS_Spaces, WLS_Service.
We created a portlet Application on our development machine using JDeveloper. When we run it from JDeveloper it runs as expected without any errors.
We created a Deployment profile for the application as an EAR file. Then we copied this EAR file over to the machine on which WebLogic server is installed (deployment machine).
On the Deployments screen of the WebLogic Server Console, we selected "Install", selected the EAR file we had created above, selected "Install as Application" and then selected the WLS_Portlet server on which to install it. Then we just kept clicking Next and Finish.
The first time we tried it, we got a NoClassDefFound exception for some class like JAXRPCServer. We did some research and found that to fix this issue we can put the containing .jar files of the classes not found into the public_html\WEB-INF\lib folder. We tried this for the above error by placing "wsserver.jar" file into the lib folder. Then we got anothe NoClassDefFound error. We again searched for the containing .jar file and put it into the lib folder. This continued for around ten to twenty errors and now we are stuck at a point where we are not able to find a way out.
The current error that we are getting is NoClassDefFound: oracle/security/jps/internal/policystore/GranteeFactory. We searched for the containing jar of this class and found it to be jps-internal.jar which is already present in our lib folder. The stack trace of the exception is:

Any help would be appreciated on this since we are stuck at this point and have no idea to get across this hurdle.
One more thing, this is the first time that we are trying to play with WebLogic or even Java. So, some of our questions or steps performed might seem irrelevant here.
Thanks,

Hi,
Another update on this issue.
To remove the error that we were getting (java.lang.LinkageError: Class javax/xml/transform/Source violates loader constraints), we tried some searching around and found out that the way to fix it is to provide correct versions of xalan.jar, xml-apis.jar and xercesImpl.jar. We downloaded the required version from the apache site and added it to our WEB-INF/lib folder in the WAR file.
Now, we are getting this error:
XPathFactory#newInstance() failed to create an XPathFactory for the default object model: http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: No XPathFctory implementation found for the object model: http://java.sun.com/jaxp/xpath/dom
What else we might be missing in our libs or do we need to check some other configurations?
Any help on this would be much appreciated.
Thanks,
Gaurav

Announcing: Developing JSF Portlets with WebLogic Portal Whitepaper

Just Released: Developing JSF Portlets with WebLogic Portal Whitepaper
A supplemental developer's guide has been published to help guide WLP 10.x customers that wish to use JSF as the web framework for building portlets on WebLogic Portal. This is a sizable document (150 pages) that covers a large number of topics. It also coaches developers on best practices and common pitfalls.
Important: It also clarifies the supported configuration of JSF within Portal Web Projects. Workshop for WebLogic by default configures a web project in a configuration that is not supported by WebLogic Portal. The guide explains how to address this:
* Change from the unsupported MyFaces JSF implementation to the supported Sun Reference Implementation (RI)
* Change from the unsupported "client" STATE_SAVING_METHOD to the supported "server"
The guide can be downloaded here:

Hi Peter!
First, I wish to thank you for the great work.
We followed your whitepaper and managed to deploy a JSF portlet on WLS.
But we are not able to register it (consume it) as remote portlet in Oracle Portal 10.1.4. The error log is as follows:
An error occurred while trying to refresh the provider. (WWC-43190)
An error occurred during the call to the WSRP Provider:
java.rmi.RemoteException: serialization error: serialization error:
unexpected null value for literal data; nested exception is:

Thank you and best regards,

Why can't I debug my JSF Portlet application after inserting an IFrame

Hi,
1) I created a jsf portlet application
2) I add a button in my jsf portlet application
3) I can debug my button's action method
4) Now I open my jsp editor and add an iframe
<iframe height="500" id="ifWindow" name="ifWindow"/>
5) I try to debug my button's action method but the debug cursor never reaches it like in step 3
6) I added a messageGroup but nothing appears there
7) I monitored "C:\Program Files\Sun\Creator2_1\SunAppServer8\domains\creator\logs\server.log" and nothing appears there
Is this a bug in Java Studio Creator or is there a problem with iframe in jsf portlet applications?
Why can't I debug a jsf portlet application if I put an iframe?
Has anyone got this to work in their jsf portlet application? What can I do to debug this simple application?
Thanks,
Marc

Hi,
I figured it out. I can debug my jsf application if I placed the iframe outside the <ui:form> element. If it's inside, I cannot debug the application. Are there any books or tutorials that I can read to get rules like this in JSF development?
