JDeveloper Tutorial does not work

Tutorial: "Developing a WEB Application Using the EJB Technology Scope"
does not work I get to step 3 - item 11 which is running the browseDepartments jsp. I get a :
500 Internal Server Error
java.lang.NoSuchMethodError: int java.lang.StringBuffer.indexOf(java.lang.String).. etc.
I have started over several time just to make sure I am following the tutorial correctly. I still get the following error. Is there an errata document on this tutorial?
Thank for any help,
Bob

Request Scope for portlets? Sharing data tutorial does not work for portlet

I created 2 identical applications, one that was a regular JSF web app, and one a JSR168 portlet. By following the "Sharing Data Between Two Pages" tutorial, I can get this technique to work without a problem in the web app, but the portlet (deployed locally using the pluto server) does not work. What is the difference between a regular app and a portlet app?
This shows that portlets apparently handle scope much differently than other applications, so any information relating to this would be helpful to pass along.

Portlet Life Cycle Differences
A portlet page is the same as a web application page in the Creator 2 application
model with differences only in the page life cycle. To best understand the life
cycle differences, you must first understand how a portal interacts with a portlet.
This interaction between portals and portlets is defined by the JSR-168 Portlet
specification. Typically a portal display in the web browser shows multiple
portlets. That is, when the portal page is displayed, there are actually multiple
portlets displaying or rendering their content. The job of the portal is to manage
how these portlets are displayed. Internally, the portal is responsible for telling
each portlet two things:
1. When to display itself
2. If there has been an action, such as a button press, performed inside that
portlet.
When a portal wants portlets to display their contents, the portal sends a render
request to each portlet showing in the portal. If one of the portlets showing in the
portal has a button tied to an action request, when that button is pushed, the
portal fires an action request for that portlet. In addition, the portal generates a
render request for the portlet and all other portlets on the page. You should note
that the portal implementation fires both action and render requests for each
action method on a portlet showing in the portal. The implication of this
interaction means the portlet page being rendered can not make assumptions
about the state of the values to be shown. Unlike a normal web application page,
a portlet page can't assume that the page being rendered in the Render Response
phase is the same page that was built in Restore View. If a portlet wants to
maintain state across repeated render requests, the portlet must use the session
bean to store stateful information.
The main point to remember is a portlet page must always be prepared to render
it's values from scratch or session data. This implies you should never bind
portlet page UI components to page bean properties or request bean properties.
Also, you should never rely on page bean instance variables that might be set
during an action event.
Hope this helps.

Example in Data Modeler Tutorial does not work as described

Using Oracle Data Developer 4, I cannot get the example on https://docs.oracle.com/cd/E57998_01/doc.41/e57984/tut_data_modeling.htm#DMDUG36173 to work as described. The Foreign Key fields in the logical model are not generated. They are only generated in the relational model when I develop the logical model. However, the names follow the template {table}_{table}_ID, which will cause problems for long table names. Now I have two questions:
1. How can get the foreign key fields to be generated in the logical model, as descibed in the tutorial?
2. Where can I see the default naming rules for generated fields used by the program and where can I change them? - I found a description how this works in Version 3, but these options do not exist anymore in Version 4.

2. Where can I see the default naming rules for generated fields used by the program and where can I change them? - I found a description how this works in Version 3, but these options do not exist anymore in Version 4.
In version 4 the template definitions are defined in the properties for the Design.
Right-click on the Browser entry for your Design and select Properties.
In the tree in the left panel of the Design Properties dialog, expand Settings, then expand Naming Standard and select Templates to display the Template definitions.

Creator2 AJAX ProgressBar Tutorial will not work with Webserver 6.1

I have been trying the tutorial on the AJAX Progress bar tutorial at
http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/ajaxprogressbar.html
Which works great with the deployment server bundled with Creator2, but when I deploy to the remote web server (Sun Webserver 6.1) it will not run.
IE gives a message on the status bar
An error occured performing an asynchronous request : [object Object]
The buttons change text, but the progress bar does not start.
The server logs are reporting
[31/Jul/2006:21:25:56] warning ( 1022): for host 192.168.1.4 trying to GET /ProgressBarExample/dynamic/bpui_progressbar_handler/writeAjaxResponse while trying to GET /ProgressBarExample/faces/dynamic/bpui_progressbar_handler/writeAjaxResponse, send-file reports: HTTP4142: can't find /opt/SUNWwbsvr/https-wkstn1.powerbox/webapps/https-wkstn1.powerbox/ProgressBarExample/dynamic/bpui_progressbar_handler/writeAjaxResponse (File not found)
Any help greatly appreciated.

Tutorial Program not working correctly

I've FINALLY got the program to run, from the tutorial Creating a Web Dynpro Applicaton Accessing ABAP Functions, https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/355b9c90-0201-0010-d2a8-89fece426526
When I run the program, I get the first screen where I can enter test information "Frankfurt" and "New York", but when I hit search, the screen blinks, but I don't get the results view. No errors are generated.
Does anyone have any idea what is happening?
Here's a screenshot of what I'm seeing: http://www.adamsblueguitar.com/test/FlightListInit.jpg
Help! I'm so close!

Hi,
there might be different reasons to not displaying.
1) might be data not available on your giving input.
2)the function module you are using the Group is not authrised in the JCO.
Your are asking the second one call your bapi execute method in init() method map the output into default View for thta you need to hardcode the input values.
But you have seen there View set As per your option you can change view.
this might helps
Thanks
Lohi.
It might helps.

ADF: auto complete in tutorial does not work

Hi all,
I'm studying ADF tutorials. Developing Rich Web Applications with Oracle ADF tutorial has a sample of Auto-complete property. I followed the tutorial from the first step but cannot go further because At Part 3, Step 3 it is not possible to drag an Autocomplete Behaviour onto Combobox. Futhermore in the screenshots, it seems possible to type into Combobox which i never see such an example before.
This is the link of the Step that i'm talking about:
http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_55/jdtut_11r2_55_3.html
Thanks in advance,

I finally found a way to correct it. When you drag and drop the whole view, JobID is type of Combo Box but it should be Input List of Values (Combo Box). To solve this you need to only delete that combo box (not the whole structure) and drag and drop the Job ID again. This time select List Of Values so it becomes a combo box with editable area. This part is not mentioned in the tutorial makes the confusion.
Edit: I just see your edit, the forum link points out the same problem. This is the workaround. Unfortunately one of the basic tutorials of Oracle ADF is confusing.

Lot of exceptions in kura-console.log. Tutorial not working for me

Hi David,
Well, now I have a wired connection to my pi and got kura up and running. But, my tutorial implementation did not work.
Later, I found there is a new 1.2.0 verion of kura, so I uninstalled 1.0.0 as per wiki steps and installed 1.2.0. I had the kura showing up again and deployed green house. But again, my LED and temperature sensors were not showing.
I was worried if my pi has gone bad, but I found that its giving right voltages at power pins. I checked it is reaching my sensors too.
Later, I looked into in the kura-console.log which looked huge. Here I am attaching it for reference. On face of lot of exceptions have occurred during its start up. I have no clues about it as I am getting started and did not want to deviate anywhere in the tutorial specification(all items used are brand new). Well only change is I have upgraded Kura to 1.2.0.
