Removing ADFBindingFilter from jsp page

Question

I have showReport()method in showReport bean (it is not registered in faces-config.xml as managed-bean) that I am calling from jsp page with JSP call showReport.showReport(). My showReport() method looks like this:
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding("#{data.documentReportsPageDef}");
DCBindingContainer dc = (DCBindingContainer) vb.getValue(fc);
OperationBinding execute =
dc.getOperationBinding("ExecuteWithParams");
execute.execute();
Headless_ documentReportsPageDef code:
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"
version="10.1.3.36.73" id="documentReportsPageDef"
Package="...view.pageDefs">
<executables>
<iterator id="DocumentReportsIterator" Binds="DocumentReports"
RangeSize="-1" DataControl="AppModuleDataControl"/>
</executables>
<bindings>
<action id="ExecuteWithParams" IterBinding="DocumentReportsIterator"
InstanceName="AppModuleDataControl.DocumentReports"
DataControl="AppModuleDataControl" RequiresUpdateModel="true"
Action="95">
<NamedData NDName="DocumentType" NDValue="@CDBR"
NDType="java.lang.String"/>
<NamedData NDName="RefNo" NDValue="12635"
NDType="java.lang.String"/>
<NamedData NDName="IsInstant"
NDValue="1"
NDType="java.lang.String"/>
</action>
<table IterBinding="DocumentReportsIterator" id="DocumentReports" >
<AttrNames>
<Item Value="Id"/>
<Item Value=".."/>
</AttrNames>
</table>
</bindings>
</pageDefinition>
It is registered in DataBindings.cpx
Everything works fine until I remove:
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
from web.xml so ADFBindingBindingFilter would not be invoked for my jsp page. I have reason for this
On execute.execute()line I get:
Resolving collection source:DocumentReports for iterator binding:DocumentReportsIterator
DCUtil, returning:oracle.adfinternal.view.faces.model.binding.FacesCtrlRangeBinding, for DocumentReports
Looking for RSI with name :DocumentReports for iterator binding:DocumentReportsIterator
DCBindingContainer.reportException :oracle.jbo.JboException
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
If I restore filter-mapping so adfBindings are used for *.jsp page I get:
Resolving VO:DocumentReports for iterator binding:DocumentReportsIterator
DCUtil, returning:oracle.adfinternal.view.faces.model.binding.FacesCtrlRangeBinding, for DocumentReports
Column count: 13
So everything works fine again.
Question: Can I make this work without ADFBindingsFilter on jsp page? I am invoking everything programmatically and I don’t understand why I need to set this filter on jsp?
With this strange implementation, I am trying to solve problem discussed in article:
oracle.jbo.common.Lock locks the application
If my idea is hopeless, please clarify me this :)

Answer 1

Ok, this is quite clear answer. Thank You.
One more thing:
In oracle.jbo.common.Lock locks the application Steve M, has left the the question open by "I'll ask one of our developers to comment in this thread on ideas for implementing this long-running report.". Maybe You could close this one too?
