Hi All,
It's been some time since I have progressed beyond displaying "Hello World" on a JSR-168 portlet and going on to navigation between JSPs and saving information through forms. At this stage I can think of using the data collected and sending it to the business layer.
Trouble is, I need to develop an example using
Struts as most of the development in my firm is done using it. I myself am more comfortable with Struts and so am eager to build a portlet using it. I came across an example on IBM's site at this URL:
http://www-128.ibm.com/developerworks/websphere/library/techarticles/0601_patil/0601_patil.html It requires you to download a zip file which contains several example wars for portlets using Struts. So far so good. But I go on to discover that after importing the wars as projects under RAD v.6, only the ones using the IBM portlet API work. The one sole example that uses the JSR-168 api doesn't show anything apart from the portlet description on the header. The page content is blank. I discovered an exception trace on the server console which goes something like:
[1/12/06 14:37:27:031 IST] 131f43e7 ServletInstan E SRVE0100E: Did not realize init() exception thrown by
servlet Struts Standard Blank: javax.servlet.UnavailableException: Exception during portlet initialization: java.lang.NoClassDefFoundError: com/ibm/wps/struts/pluto/base/ErrorInfo
at com.ibm.wps.pe.pc.std.core.PortletServlet$PortletClone.<init>(PortletServlet.java:409)
....
..
.
This is when I did not even touch the code of that example app and just ran it as is. Don't know what this exception is about...tried looking for the unavailable class "com.ibm.wps.struts.pluto.base.ErrorInfo" in the library jars but couldn't find it.
I know there is nothing wrong with the
IDE itself (RAD v.6) because I have developed some non-Struts examples which work..
Does anyone know whats up?
