How to create graphs on JSP page in JDeveloper 10.1.3

Hi all,
Is there an easy way to create graph objects with JDeveloper 10.1.3? I have taken a look to some tutorials, but it looks like they all use the "drag/drop graph from the data control palette" method.
E.g. I got example 88 to work from http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html, but I have no idea how to get the BIGraphDef1.xml object and how to link it to a set of data.
Are there some tutorials to show how graphs can be used in JDev 10.1.3?

Frank,
This is what I did to implement the graphic manual, but I think, I forgot something...
1. create a new application with projects DataModel and UserInterface
2. in the DataModel I created a similar master/detail view as the one of Steve, this is named:
TestModuleDataControl
\--DepView
__\--Deptno
__\--Dname
__\--Loc
__\--EmpView1
____\--Sal
3. I created a new jspx page and added a graph tag:
<f:verbatim>
<graph:Graph data="${bindings.DepartmentsEmployeesInDepartmentGraph}"
imageHeight="200" imageWidth="400"/>
</f:verbatim>
4. in the page definitions I added
<graph id="DepartmentsEmployeesInDepartmentGraph"
IterBinding="EmployeesInDepartmentIterator"
ControlClass="oracle.dss.graph.Graph"
SeriesLabel="Ename"
GraphPropertiesFileName="userinterface.BIGrap1hDef1"
SeriesType="SINGLE_SERIES">
<AttrNames>
<Item Value="Sal"/>
</AttrNames>
</graph>
5. I added also the iterator:
<iterator id="EmployeesInDepartmentIterator" Binds="EmpView1" RangeSize="10"
DataControl="TestModuleDataControl"/>
6. I copy/pasted the BIGraphDef1.xml from Steve's project into 'Application Sources'\userinterface.
7. in the web.xml file in WEB-INF I added:
<servlet>
<servlet-name>GraphGeneratorServlet</servlet-name>
<servlet-class>oracle.jbo.html.jsp.graph.GraphGeneratorServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>GraphGeneratorServlet</servlet-name>
<url-pattern>/GraphGeneratorServlet</url-pattern>
</servlet-mapping>
8. when I run the page, I can't see the graph and there are also no errors. I think I mis a global setting somewhere...
Is there anything I forgot to do?
note: if I add a new jsp page into steve's application, I do can see the graph if I perform the steps mentioned above...
I just found out that, If I create the graph on a page which is in the root directory, then it works. If I put it in a subdirectory, it doesn't:
- create graph as mentioned above on a page: web content/myGraph.jspx --> works
- create graph as mentioned above on a page: web content/app/myGraph.jspx --> doesn't work...
Does somebody know where to put a setting/parameter to get the Graph visible in the subdirectory app?

Hi Monika,

How do I migrate my charts from Oracle Graphics to the new graph format in Oracle Reports 10g?
Since release 9i, Oracle Reports uses Business Intelligence Beans (BI Beans) to create and display graphs in reports. There is no direct migration path from Oracle Graphics to the BI Beans graphing functionality. As such, the user will need to rewrite all of their graphs using the new Graph Wizard within the Oracle Reports Builder 10g. Oracle Reports 10g supports over 50 graph types, including 3D graphs. However, keep in mind that it does not support some special types, such as Gantt charts.
It seems direct graph 6i migration is not possible from reports10g.
It is asking to use the chart wizard again with your query.
Please follow the above two link it may helps u a lot.

How to Create Graph In forms 10g

Dear All
How to create a graph in Forms10G ?
Can you please give a small full example step by step ?

This is a fairly common question in the Forum. Searching the forum would have given you your answer. Graphing data in a form is now handled through a Java Bean. You will need to download and install the Forms 10g Demo's to get an example (which includes the JavaBean) and the instructions on how to use the bean.

How to create session in JSP & Servlet

Hi All
I'm really new to JSP & Servlet. So I want to know how to create sessions and how to pass details to another web page
Thanks
Padma

You can easily pass objects from one jsp or servlet to another.
On your servlet execute method (for example), you can do this as follows:
HttpSession session = request.getSession();
User u = new User();
session.setAttribute("user", u);And get it again on other servlets:
HttpSession session = request.getSession();
User user = (User) session.getAttribute("user");I hope this helps you.

RE: How to create a secure JSP?

I am interesed in creating a web application using the J2EE standard with one of the pages being a page where credit card info will be entered by the user and then stored in our DB. Everything will run server side with this app.
Could someone please let me know how to achieve the highest security for such an application. I want to ensure that the information the user will enter could NEVER get into the wrong hands. I know that NEVER is a strong word here, but I want to achieve the best security possible.
Could you please make any suggestions possible that would assist me in doing this?
Thanks in advance for your assistance!

This will be an Internet application and it doesn't matter that much if the application is slowed down. It is a good trade off for good security as long as it is not too slow.
How easy is it to add SSL security to the site? Is this the best method? In regards to ensuring the mySQL DB is secure - what methods are used to do this?
I appreciate your comments.
Thank you!
You could start by using SSL, this will slow down the
application.
Also make sure the data is secure in your database.
Will this be an intranet or internet application?

Here is some code that creates xml for any SQL that returns a ResultSet. Note this uses my default out-of-the-box XML template, but you can quickly create and use your own templates to generate xml to look anyway you desire.
FormattedDataSet fds=FormattedDataSet.createInstance();
Map miscData=new HashMap();
map.put("rootElement", "musicgroups");
String xml=fds.getFormattedDataSet("select * from groups", miscData, "xml1");
String xml has the value:
<musicgroups>
<row rowID='1'>
<group_id>1</group_id>
<group_name>Rolling Stones</group_name>
<type>Rock</type>
</row>
<row rowID='2'>
