Weird BC4J HTML error -- method not found

Question

Hey all,
I'm getting a strange new error, and I don't think I even changed anything since the last build. We're using BC4J in a "proof of concept" capacity right now, and I have a fairly simple page that was working fine yesterday. It's a browse form, without any update/insert/delete stuff, just used for viewing a log from the database.
Here's the error I'm getting:
java.lang.NoSuchMethodError: oracle.jbo.html.RequestParameters: method addParameter(Ljava/lang/String;Ljava/lang/String;)V not found
     at oracle.jbo.html.jsp.datatags.ComponentTag.buildUrl(ComponentTag.java:55)
     at oracle.jbo.html.jsp.datatags.DataHandlerTag.getUrl(DataHandlerTag.java:44)

     at com.caucho.server.TcpConnection.run(TcpConnection.java:140)
     at java.lang.Thread.run(Thread.java:498)
And here's the code that causes it:
<%@ page language="java" errorPage="errorpage.jsp" contentType="text/html;charset=windows-1252" %>
<%@ taglib uri="/WEB-INF/DataTags.tld" prefix="jbo" %>
<jbo:ApplicationModule id="am" definition="ComposerWeb.InventoryUpdateBizModule" releasemode="Stateful" />
<jbo:DataSource id="ds" appid="am" viewobject="InventoryUpdateLogWebView" rangesize="20" itermode="LastPagePartial"/>
<jbo:DataHandler appid="am" />
Any ideas?
Thanks,
Jeff Davis

Jeff,
Somehow two versions of the BC4J HTml runtime library must be mixed.
This error would come up if the application is compiled using a 902 version of bc4jhtml.jar but run with the 903 version.
Check that all instances of bc4jhtml.jar match in your application and in <jdev_home>\BC4J\lib.
