Hi,
I did reach out to Apache Struts as per your suggestion and got the follow=
ing reply from Apache Struts group. . =20
--------------------------------------------------------------------------=
---
How is it related to Struts 1 ? As I know BeeHive is a page flow control
engine (donated by BEA years ago) and it looks like a configuration
problem, but rarely unrelated to Struts 1.
--------------------------------------------------------------------------=
-------
Even I am under the same impression that some configuration piece is wrong=
 and hence trying for some help or assistance again here. Just an addition=
al note - This project works fine in Weblogic and we are trying to port it=
 to JBOSS/Tomcat.=20

What we did is to remove bea dependents and use apache equivalents to run =
in it Tomcat/JBOSS. The changes we did to working bea code are as follows

In jpf-struts-config.xml
<controller className=3D"org.apache.beehive.netui.pageflow.config.PageFlow=
ControllerConfig" inputForward=3D"true" processorClass=3D"org.apache.beehi=
ve.netui.pageflow.PageFlowRequestProcessor">

In struts-config xml the following change
 <controller className=3D"org.apache.beehive.netui.pageflow.config.PageFlo=
wControllerConfig" inputForward=3D"true" processorClass=3D"org.apache.beeh=
ive.netui.pageflow.PageFlowRequestProcessor">

In beehive-netui-config.xml
<expression-language>
            <name>compat-netuiel</name>
            <factory-class>org.apache.beehive.netui.script.el.ExpressionEv=
aluatorImpl$NetUIELEngineFactory</factory-class>
        </expression-language>
    </expression-languages>
Commented
<!--=20
    <iterator-factories>
        <iterator-factory>
            <name>rowset</name>
            <factory-class>com.bea.wlw.netui.util.iterator.RowSetIterator$=
RowSetIteratorPlant</factory-class>
        </iterator-factory>
    </iterator-factories>
     -->

I am hoping with this detailed info someone can provide some valuable inpu=
ts as to whether if I missed any key configuration step or some jar additi=
ons etc for making it work in Tomcat/JBOSS. Again the=20deployment seems t=
o be fine and when I access the jpf welcome file then see the exception be=
low in console. Are there any other places I need to take a close look at =
with respect to configuration.=20

Thanks for any kind of help/assistance and is much appreciated.

Regards,
Shaikh

This seems related to Apache Struts, and you should redirect your
question to their user mailing lists :
