Chart Possibilites with JDeveloper
Hi,
I want to develop an application that draws charts with these properties.
1 - Dynamic, soft real time update of data on the charts.
2 - X axis, almost always with respect to time, lowest level of granularity usually in minutes.
3 - Possible to Zoom out to, say 2 weeks of data, which shows reasonable graph, of say values plotted in days, and Zoom in to graph of an hour show a reasonable graph, of say in minutes. (In other words, for 2 week graph, we don't want all the minutes plotted within the 2 weeks)
How much effort is involved in developing such an application?
null
Deployed how?
Have you looked at the Chart tab in the toolbar ( Perspective ). Will that get you started in the right direction?
I'd also suggest looking at other third party utility packages according to your need.
For example, we use Oracle Reports/Graphics to generate html pages for a website. These can be shown from JDeveloper. ( Either static, or dynamically via a Reports 6i server under iAS ).
This task can be quite trivial... or quite complex ( from an infrastructure standpoint ). The more complex, the more powerful solution you'll have for solving a lot more tasks than just generating charts. The more trivial... the more you'll have a spot solution that'll meet an immediate need.
Good Luck.

Are there Any Charting solutions that works with JDeveloper/ADF?
Are there any Charting solutions ( e.g. barchart, piecharts, etc) that works with JDeveloper / ADF ?
This question came up here once before. I think the conclusion is: No, not with vanilla ADF. However, if you're interested, the thread did mention some other library you might want to try.
Good luck,

Business Services development with jDeveloper
We are making use of the Business Services feature in JDE to expose business functions as web services, that's great and working.
we have one problem with jDeveloper during development.
we can create a new business service from OMW in JDE and invoke jDev from there, that's fine.
then we can put codes in the project in jDev, that's fine.
then we can publish the code as J2EE web service, that works as well.
then if we restart jDeveloper after that, the J2EE web service doesn't work in the jDev embeded web server any more.
we always have to delete the web service in the project and go through the same wizard steps to generate the web service again.
it's very annoying when you have more than a handful of web services you want to expose.
and if you use the WSDL in a client project to call this web service, you have to remember to give the web service the same name when re-generating otherwise you have to reimport the WSDL again on client side, it can be another huge pain if the client is Oracle BPEL.
so my question is, why is this happening? is it some settings in jDev that we didn't set right? or is it a bug in jDEv and is there a work around?
thanks in advanced!What error did you get?

Problem with tutorial; "Build a Web Application with JDeveloper 11g Using "
I've got a rather new installation of Vista Business x64 on my developer rig, and last week I installed the new JDeveloper 11g version. The installation was all-inclusive, no customization on my end.
In addition I've got a test installation of an Oracle DB 11gR1 on an available server here.
To familiarize myself with the new JDeveloper I decided to spend some time with the JDeveloper 11g tutorials found here: http://www.oracle.com/technology/obe/obe11jdev/11/index.html.
I've started twice on the second tutorial, "Build a Web Application with JDeveloper 11g Using EJB, JPA, and JavaServer Faces", and find myself repeatedly stuck at step 19 in section "Creating the Data Model and Testing it".
It seems impossible to deploy the application to the default application server. The server starts fine on its own, I can access it via the admin console on port 7001 and it looks good. However, when I try to run the HRFacadeBean funny things are happening, symptomized by the following error messages seen in the IDE log-area:
The "Messages" pane displays:

I'm not that familiar with these things but it seems to me that there is an issue with port numbers here. The application seems to expect a app.server service at port 7101, but does'nt find one.
Any suggestions on how to fix this problem would be appreciated?
LA$$EJupp,
It fails in a similar way.
What I did was; create a simle 'Hello World' html file, saving it with the jsp extension. In Jdev11g i made a new application and an emtpy project, then loaded the jsp file and made it the default run-target. This compiles nicely.
When running the project it first attempts to start the WebLogicServer (WLS). After a few minutes it is started as seen in the "Running: DefaultServer" pane:

But, of course, the server is actually running as I can access it via its Admin Console.

Process exited.
The WLS is still running though as I can still access its adm console.
To me it seems that it is attempting to start a separate instance of the WLS for each run attempt, but then I could be wrong.....:(
Later I'll try to change the default WLS port from 7001 to 7101 as suggested in another port here.
I must admit that I'm a bit surprised that the JDev11g doesn't work fine at this very simple level when performing a default install. -
How to use BC4J with JDeveloper 9i in a Team

I'm not sure if I'm to stupid, but to say the truth I didn't found the clue how to share a BC4J Application between several develeopers. Maybe someone can give me a hint.
That's my situation:
Our team is going to develop a web application using BC4J and BC4J-JSP, nothing special I think.
But my problem is, that BC4J and especially the wizards refer to a lot of different files. Even simple changes often result in multiple files being changed in different parts of the project.
Creating a view link between view objects in two packages for example changes the view objects in both packages. Also the project (.jpr) file or several "BC4J.xcfg" files are changed very often.
So it is not easy to find parts of code from which I can say they are owned by one developer and others which are owned by another. Most often, if you have to merge the work of different developers, you have to edit the BC4J-XML-Files using an external editor. Or did someone find a better way? Please tell me!
So, what is the best way to share code between developers?
Should I partition the application by packages?
- advantage:
it allows a fine partitioning
- disadvantages:
it has the great danger that BC4J makes changes in other packages which will be overseen when merging.
Should I create a projects for each developer and distribute code between the projects using libraries?
- advantage: no unseen changes will happen, as the libraries are readonly.
- disadvantages: no view links between view objects in different projects (Libraries) are possible! Also a lot of "load errors" can occure when updating a library, which have to be manually corrected in the dependent projects.
Are source code management systems a real help in this problem or do they just "manage" the problem? I already tried SCM and PVCS but was not very happy with the way of working. As JDeveloper is not "really easy" to use with theese tools.
So I would like to get any hints how other developers are dealing with this problem. Are you using BC4J with JDeveloper 9i in a team? Please tell me how do it and how you have partitioned your application.
Thanks in advance
Frank BrandstetterHi,
I'm not sure whether my answer is good enough for you, but it might help.
First of all, you have to use JDev 9.0.3, because 9.0.2 has big problems with associations/view links between objects in different projects.
Creating a view link between view objects in two packages for example changes the view objects in both packages. Also the project (.jpr) file or several "BC4J.xcfg" files are changed very often.This is not completely true in 9.0.3, as you may choose not to create an accessor in the imported object (and usually you don't need it neither!). As for bc4j.xcfg, there is a trick: define a "standard" database connection name to use all over your project! This will prevent modifying these files all the time!
Should I create a projects for each developer and distribute code between the projects using libraries?
- advantage: no unseen changes will happen, as the libraries are readonly.
- disadvantages: no view links between view objects in different projects (Libraries) are possible! Also a lot of "load errors" can occure when updating a library, which have to be manually corrected in the dependent projects.I would say, projects for each application component, which by chance will be managed by a single developer at a time.
As for the disadvantages, in 9.0.3 you are able to properly create associations and links using read-only objects. Hopefully, the release version will solve some generation inconsistencies...
Concerning the errors that occur when modifying a library, this might be balanced by the relative independence of the components... If you are able to develop following the dependency tree, you will not meet the problem very often.
Are source code management systems a real help in this problem or do they just "manage" the problem? I already tried SCM and PVCS but was not very happy with the way of working. As JDeveloper is not "really easy" to use with theese tools.Indeed, I do not have a SCMS really able to manage merges in the BC4J XML files... We rather try not to arrive there!
So I would like to get any hints how other developers are dealing with this problem. Are you using BC4J with JDeveloper 9i in a team? Please tell me how do it and how you have partitioned your application.I really hope that my hints will help.

One more nugget: Chart zoom with the "Mouse Over" effect
Hello all.
Just read my signature first, it might explain a lot. I do not intend to compete with Darren and I don't think this "nugget" (at least it supposed to be one) will amaze any of the LV veterans and this forum is rich of them. But maybe it will bring some new ideas to some of you or maybe it will be useful for some LV beginners (like me). It is very likely, my code will have some lapses, but please be gentle pointing that out to me. If you feel a need, you can always optimize the code and develope it further. Just don't forget to share!
So back to the point.
I am developing a project using LV. In my program there is a waveform chart which has to show 4 plots. Depending on the length of the X Scale, it sometimes gets hard to see the plots clearly because of their density.So I decided that I need a tool, which would zoom the chart in. And this is what I have came up with after a few "Google" searches to check which part of the bike is already invented and also a bit of programming by myself.
Maybe you guys (at least the veterans) know the BetterVIEW Consulting LV example where they have implemented the Mouse Over effect. So a part of their example has been used in this tool and part of the credit must go to them. I thank them a lot
This tool uses a cluster and its property of visibility to show/hide the cluster depending on if the current position of the mouse cursor is in the desired range or not. The program also gets the image of the chart and returns the subset of the image. The subset is taken for the area arounf the mouse cursor. So if you move the mouse, the zoomed in area will also chage in response. After that, the subset of the image is zoomed in for better view.
The user might chage the zoom factor during the execution. Also it is possible to turn the zoom option On or Off if you don't wish to see it for the moment.
This is how the front panel looks like:
And this is the image of the block diagram (see the attached files for the vi, the VI Snippet tool distorts the code too much, so I haven't added it):
I haven't found anything the same in the forum. Yet I'm a newbie here and I don't have that much experience surfing it. If it wouldn't be something new (in the forum, not necessarily to some of you personally), just ignore the thread. I hope this was worth your time and your attention.
Good coding
Message Edited by Giedrius.S on 02-11-2010 12:46 PM
While evaluating my code please have in mind that I am a LV novice. Therefore sometimes my code might violate some coding rules that I have to learn about myself. But how else could I do that...
Chart zoom with "Mouse Over" effect
Attachments:
Zoom.vi 198 KB
Mouse_pos.vi 20 KB
Check_pos.vi 18 KBVery nice Giedrius.
It takes guts to "step up to the chalk board" so I will do what i can to give you some ideas to think about. This is similar to the type of feedback I offer durring our in-house code reviews.
1) The floating property nodes outside the loop are not sequenced by wires so they could execute after the loop starts. Sometimes this could cause weird errors. Seq with the error cluster.
2) Property nodes can be re-sized so you can apply more than one property setting in the same call. Property node have to execute in the UI thread (which is single threaded) so using a single nodes will force a single context switch rather than one for each.
3) Setting the same property repeatedly in a loop just burns CPU. THe Scale min for both X an Y can be moved outside the loop ?
4) THe Wait Until Next ms" function does not get used in any of my code. It is not a way to get a fixed wait but rather a random wait. If you code completes 1 ms after the next multiple, the delay is double less 1 ms. If you have multiple loops using them and it f the delay for each are not unique prime numbers, then the "Wait until next ms multiple" is a good (cough cough) way of getting them all to wake up at the same time and fight for the CPU.
5)An Event Struture to monitor mouse enter/leave and mouse move (this would have to be a sepearte loop) is easier on the CPU than polling.
6) Is that math in the case to handle the Chart position on the FP? If so then using the property nodes for the chart to find its postion will let you code adapt to GUI changes.
7) Right to left wires are not well recieved.
8) A Bundle by Name is prefered over a "Bundle" since it is self documenting. I know the Picture function so I can see that is the rectangle you are specifying but reader not famliar with that function would not be able to "READ" the code without poking at it.
9) THe event structure would also help with setting the Zoom factor. Only poke it when you have to.
That is all that comes to mind at the moment.
Again thank you!

Performance issue with Jdeveloper
Hi Guys,
I am experiencing strange performance issue with Jdeveloper 10.1.3.3.0.4157. There are many other threads regarding the performance issue in this forum, but the problem I have is a little bit different.
I have two computers: one is Athlon 3200+ with Vista and another one is P4 dual core 6400 with XP (service pack 2). Both of them have 2GB memory.
I am running the same simple project on both computer, but only the one with Vista has the problem. The problem is very similar to the problem mentioned in the thread:
Re: IDE has become extremely slow?
But it's much worse. It only happens only on JSF pages. Basically, any operations on the JSF pages are very slow. Loading the page, changing the attributes of a button in source editor, or even clicking the items in the design view take forever to run.
The first weird thing is that it may use 100% CPU, but it never recover, which means the 100% CPU usage never stops or when it stops, the Jdeveloper stops responding.
The second weird thing is that the project is not big. Actually, it's very small. The problem started to happen since last week. There are not big changes during the period. The only thing I can say is that we created two more JSF pages.
The third weird thing is that the same project never happened on the P4+XP box. When I open the project on the P4+XP box, it’s always fast and no CPU spike.
Any advises are welcome!
Thanks,
StevenHi Guys,
I re-made a simple test project for this problem and now I now always reproduce the problem in JDeveloper on both system (XP & Vista). Everytime I open this jspx file in the source editor and try to scroll up/down the source file, or manually delete an attribute, JDeveloepr will hang and the CPU usage is 0%.

Error after deploying a JSP Application developed with jdeveloper
Hi there
Running Oracle Enterpride Edition 8.1.7
including Oracle Http webserver
I'm trying to run a JSP application developed with Jdeveloper
through the oracle http server included in
Oracle Enterpride Edition 8.1.7
Think I have modified alle the .conf files correctly
I get the message :
"Error Message: java.lang.RuntimeException: JSP Registry could not locate runtime property file:ORDERS_ORDERS_PKG_ORDERS_PKGModule.properties"
Of course I know ,this file should be deployed as well. I have done this.
Any ideas what's wrong ?
Or can anyone point me to a (proper) document that decribes (correctly and completely) alle the steps that need to be done ?
Many Thanxs
Regards TJ

Impossible to use CallbackHandler for WS-Security with Jdeveloper 11.1.2.1
I have created WS client and proxy with JDeveloper 11.1.2.1 wizard. Security: oracle/wss10_username_token_with_message_protection_client_policy.

PasswordCallback pc = (PasswordCallback)callbacks[i];
pc.setPassword("pwd".toCharArray());
} else {
throw new UnsupportedCallbackException
(callbacks[i], "Unrecognized Callback");
When I try to launch client, I get the following message:
Exception in thread "main" java.lang.ClassCastException: package_test.ClientSecurityHandlerCallback cannot be cast to javax.xml.ws.handler.Handler
I have tried another approach, with
public final class ClientSecurityHandler implements SOAPHandler<SOAPMessageContext> , but I don't manage to put username in the existing uesrname/timestamp token.
How can I set uid/pwd to work with this security scheme?

Using Struts with JDeveloper, BC4J and OC4J 9.0.2
Is it feasible to use Struts with JDeveloper 9.0.2, BC4J 9.0.2 and OC4J 9.0.2? We have an application that uses the BC4J JBO tags in version 9.0.2. We wish to use Struts and we want to retain the use of the JBO tags. Is there a way to do this without upgrading to 9.0.3?
Here are two related questions:
Can we upgrade to oracle9iAS 9.0.3 yet still use JDeveloper 9.0.2 and BC4J/JBO 9.0.2?
Can we upgrade to JDeveloper 9.0.3 and BC4J/JBO 9.0.3 yet still deploy to oracle9iAS 9.0.2? -
Is it possible to use SOA Suite 11g with JDeveloper's integrated WebLogic?
Is it possible to use SOA Suite 11g with JDeveloper's integrated WebLogic? Or do you have to install an external WebLogic?
Thanks for help.
Edited by: user7722720 on 07-Dec-2011 02:04Hi
By default, NO it is NOT possible to deploy any SOA Applications on Integrated Weblogic Server that comes with JDeveloper. This integrated weblogic server is very light weight basic weblogic server with single domain (only 1 AdminServer) to deploy a standard J2EE, ADF Applications like EJBs, WebApps, WebServices, ADF Apps etc. BUT SOA (having BPEL, BPMs etc ) cannot be deployed.
There is an option to upgrade this integrated weblogic server and install SOA on top of this. Like download soa installer that matches with your JDeveloper version and install soa on top of this weblogic. BUT I strongly do not recommend this, because you will not be able to upgrade iin future to the latest versions.
Yes, its always better to install the standalone Weblogic Server that matches with your JDeveloper version. Then install SOA on top of this Weblogic Server. Then create RCU Schemas in any Oracle Database. Run config wizard and create a SOA Domain. Now integrate this in your JDeveloper to deploy any soa applications.
Make sure that JDeveloper, Weblogic Server, SOA Software, RCU all these versions should match and they should be same.
Thanks

As a straight A student of Computer Science, I put my hands on database development of an information system project for our CS faculty this summer. JDeveloper is used as the IDE for such project.
I have learnt Java 2 and something about Oracle database in my courses. Now, after reading the product introduction and a short online course outline in iDeveloper2001, I have a brief idea about it. But since I can not afford much, how to learn more about it? Could you offer me some advices?
Thanks a lot!The online users guide and documentation is the best place to
start to learn how to use JDeveloper.

Web services with Jdeveloper using weblogic as server
Hi,
I try to test creating PL/SQL web services by using a connection hosted by weblogic server instead of OC4J. The problem is what I try to publish a package of the database in the second stage when it asks for the connection to use, in the list I don't found the connection I create to weblogic . It presents as choice only connections used the server OC4J.
I do not Know if it is possible to publish a package as web service by using weblogic server connection, and how to do it.
can anyone help me please .
NawalWeb services can only be published to BEA if you install Apache SOAP on BEA and use the Apache SOAP option of JDeveloper. The J2EE Web Services implementation framework is specific to Oracle9iAS.
The PL/SQL Web Services server implementation is based on the J2EE Web Services option and as a result is not really portable to BEA.
To publish a PL/SQL Web service on BEA with JDeveloper you would have to write the Java wrapper code to invoke the stored procedure using standard JDBC and then publish that Java class as a Web service using Apache SOAP. Then if you had Apache SOAP installed on BEA you would be set.
Portability of Web services implementations is a big feature coming with JAX-RPC - currently what most vendors have is interoperability between implementations because of things like SOAPBuilders and WS-I. When JAX-RPC becomes part of J2EE 1.4 roughly in June and vendors start putting out implementations on it you should get closer to portability.
In the meantime, the easiest way to get portability is to use the same SOAP server on both servers - Apache SOAP is a good example.
Hope this helps.

Web services with JDeveloper - serialization error
Dear all,
I have an issue with web services created with JDeveloper 10.1.3.2.0.
Namely, this is what I do:
1. I've created some TopLink classes from tables; one of this classes is called Task (and it's located in a package called "integration")
2. I've created another class, called Integration, where I use these TopLink classes; in this new class I have a method called getTasksStatus, which returns an ArrayList containing Task objects
3. I've created a web service from this class (Integration) by right-clicking on the class name in Applications Navigator and choosing Create J2EE Web Service.
When I call the method getTasksStatus from the test web service (endpoint),
I get this error:
Oct 8, 2007 7:14:30 PM oracle.webservices.service
SEVERE: serialization error: no serializer is registered for (class integration.Task, null) serialization error: no serializer is registered for (class integration.Task, null)
When I call a method which returns a primitive type, everything is fine.
I understand the problem, but I don't know a solution yet. Could you please help ?
Thank you,
Best regards,
SorinOne solution to this problem is to make sure that the complex type you are using in yous service interface do implement the JAVA Bean as per the spec (at least Oracle's interpretation of it).
You need to have getter/setter for all members and you need to have an empty ctor() to create new instances of your objects. In some cases, the design time let you get by, but the runtime fails in the code generation.
In your case, the 'Task' class may have some issue.
Hope it helps,
