Action method called in standalone OC4j but not OAS

Question

I am setting up a test environment on Solaris x86 machine and have run into an odd issue concerning an action method being called which seems to be an issue for Oracle Application Server (OAS) but not an issue for stand alone OC4J.
The application is using Java 5, Spring 2.5, Java Servlet 2.3, Struts 2, iBatis 2.2, Sitemesh, and Display Tag to name some of the parts that are in play.
The platform is a Sun Fire X2100 server running Solaris 10 OS (64-bit). The application server version is 10.1.3 (Solaris x86, 64-bit) connecting to Oracle database server 10.2.0.2.0 (Solaris x86, 32-bit). The stand alone OC4J that I used for comparison was 10.1.3.4.0 (also run under the same Solaris machine but not while the application server was running).
Going from one JSP that contains a list of items ("authority ids" in this case) to another JSP which displays detailed information about one item (chosen by clicking on a hyperlink in the list), it appears that the setter action method (which sets the 'sid' property) does not get called under OAS so the page displays empty fields. Same code running under the stand alone OC4J, the setter method does get called and the fields are populated on the details page. In both cases, both deployments are hitting the same database and the data is successfully retrieved from the database (into the action class). In both cases, the parameter that is set by this action method is present in the URL for the detail page.
Snippet of code from the JSP that loads the authority ID list (and passes the sid in the URL):
<display:table name="authorityIdList" cellspacing="0" cellpadding="0" requestURI=""
    defaultsort="1" id="authorityIdTypes" pagesize="25" class="table" export="true">
    <s:url id="editurl" action="editAuthorityId" includeContext="false">
      <s:param name="redirectUrl" value="%{returnUrl}"/>
    </s:url>
    <display:column property="fieldName" escapeXml="true" sortable="true" titleKey="authorityIdType.fieldName"; style="width: 34%" url="${editurl}"
      media="html csv xml excel pdf" paramId="sid" paramProperty="sid"/>Snippet from the authority ID detail form where the sid should be populated:
<tr style="display: none"><td>
      <s:hidden key="sid"/>
        <s:hidden name="redirectUrl"/>
    </td></tr>Snippet from the action class that contains the setter for the sid property:
  public Integer getSid() {
        return sid;
  public void setSid(Integer sid) {
        this.sid = sid;
  }Snippet from the resulting html page for the list includes the sid for each item in the list.
<td style="width: 34%">DODAAC</td>
<td style="width: 25%">DODAAC</td></tr>
<tr class="even">
<td style="width: 34%">DODAAN</td>
<td style="width: 25%">DODAAN</td></tr></tbody></table>Under the stand alone OC4J, the setter method is called, so the sid is populated (and the item detail data from the action is retrieved and displayed).
Snippet from the resulting detail html page from the stand alone OC4J:
    <tr style="display: none"><td>
         <input type="hidden" name="sid" value="1" id="saveAuthorityId_sid"/>
        <input type="hidden" name="redirectUrl" value="http://system01:8888/MyApp/admin/authorityIdTypes.html"; id="saveAuthorityId_redirectUrl"/>
    </td>Notice that the sid value as well as the redirectUrl value are populated under standalone OC4J.
Under OAS, the setter method is not called, so the sid is not set (and none of the other item detail fields are populated).
Snippet from the resulting detail html page from OAS:
   <tr style="display: none"><td>
         <input type="hidden" name="sid" value="" id="saveAuthorityId_ sid"/>
        <input type="hidden" name="redirectUrl" value="" id="saveAuthorityId_redirectUrl"/>
    </td>Notice that the sid value as well as the redirectUrl value are empty under OAS.
Any ideas on what I need to change in OAS configuration to make this work under OAS (if this is a configuration issue)?

Answer 1

I found another case that may be clearer.
A confirmation page on the application server shows that the redirect url is not being populated:
<form id="confirmation" name="confirmation" onsubmit="return true;" action="/MyApp/admin/confirmation.html" method="post"><table class="wwFormTable">
     <input type="hidden" name="redirectUrl" value="" id="confirmation_redirectUrl"/>
   <tr>
    <td colspan="2"><div align="right"><input type="submit" id="confirmation_continue" name="method:proceed" value="Continue"/>
</div></td>
</tr>
</table></form>Same code running on the standalone OC4j does populate the redirect URL:
<form id="confirmation" name="confirmation" onsubmit="return true;" action="/MyApp/admin/confirmation.html" method="post"><table class="wwFormTable">
     <input type="hidden" name="redirectUrl" value="http://system01:8888/MyApp/admin/users.html" id="confirmation_redirectUrl"/>
   <tr>
    <td colspan="2"><div align="right"><input type="submit" id="confirmation_continue" name="method:proceed" value="Continue"/>
</div></td>
</tr>
</table></form>So it appears that the application server is having problems passing parameters to pages.
I have been digging through Oracle documentation, but I haven't found any clues on how to fix the issue.
Any help would be appreciated.
Thanks,
