We are currently evaluating NetAdvantage for JSF to be used at our presentation layer. Please let us know whether these controls are compatible in our environment where we use Oracle AS 10g, JSF1.1 with MyFaces, EJB 3.0 and Toplink.
The editor we currently use is Jdeveloper 10.1.3, which do not support UI development as Eclipse or IBM RAD, but we are currently concerned about the manula configuration to work with these controls manually. I got the trial version and trying to run a simple DataGrid employee's sample but i am getting this error. "Unable to instantiate tag: webgrid:gridView (class: null) Make sure that the tag class is available and that the tag library containing the class is not excluded from this application." where as taglib and the library is included in project.
Help regarding configuration is requires ASAP so we can finalize the library to work with;
Thanks & Regards,
Hello ayeshan, Please make sure to copy the Infragistics JSF jar files into (Current project)/WebContent/WEB-INF and resource folder into (Current Project)/Webcontent. Please follow below link to configure your application.

Thanks you for your response SGowdra,
Good to know that we can go with NetAdvantage, but i'm still unable to configure it in our working environment;
I created a simple project in JDeveloper and placed resources and jar files as addressed. I further copied the code used is gridView sample, but i get the same error.i.e.
Unable to instantiate tag: webgrid:gridView (class: null) Make sure that the tag class is available and that the tag library containing the class is not excluded from this application.
I tried to manipulate code as by extracting tld file in web-inf folder and extract class files in web-inf/lib but get the same error. The class it seems not to find can be referenced in my java classes, so it is confirmed that those classes are available in class path.
Whatever we require for a JDeveloper project, i tried it and failed. The worse part is that i already invested more than 4 days in this hit & try method and we cannot delay on this.
Can you manage some help for me to configure the project asap, so the pending development resumes.
I hope you understand my concern;
Hello Ayesha, This is just to know that we have created a support case for this issue.
You solve you problem?
i have this problem to. i use oracle oc4j and is needed pack the jsf libs into WEB-INF/lib. But when i go run the application application, i receive the message "Error: Unable to instantiate tag: t:dataTable (class: org.apache.myfaces.generated.taglib.html.ext.HtmlDataTableTag) Make sure that the tag class is available and that the tag library containing the class is not excluded from this application. "I try solve this using a "explicit tld locations" but dont have effect.
I solve my problem changing configurations at deployment descriptor of Oc4j, this configurations:
- At orion-application:
<orion-application component-classification="internal" >
<remove-inherited name="default.locale.taglibs.on.my.server" />
And at orion-web of my web app:
<web-app-class-loader search-local-classes-first="true" include-war-manifest-class-path="true" />
When this i use the libraries inside the applications and not use the libraries of server. The library version of WAR its the library version used for my application.
I search this post at Oracle forum and use configurations at this link:
