Spring 3 MVC Annotation Portlet <form:form> submission NoHandlerFoundException

[WebCenterGuy]

Hi

I am trying to run spring 3 MVC portlet on WebCenter portlet container. When i try to submit a Form (<form:form> tag), i get NoHandlerFoundException exception.I created a ActionURL with an action parameter (action=sayHello). It seems when the form (<form:form> tag) is submitted spring framework is not able to get action parameter correctly (stack trace shows it as : wlp__ns1853309770__action=sayNow).
But if i use the same actionURL in the HTML form tag, it works well.
Am i missing anything? Please see the configuration below.

Thanks for help.

Hi Guys,

I have figured out the solution for this issue. The <form:form> tag has htmlEscape true by default. This adds "amp;" to every request parameter.
Either set it to false in the <form:form tag or make it false in the web.xml
<context-param>
<param-name>defaultHtmlEscape</param-name>
<param-value>false</param-value>
</context-param>

I am getting the following exception when this portlet is deployed into weblogic. It appears that weblogic has a default spring implementation and i may have to turn it off. Have you come across this issue.

i know this message has been posted a while ago, but want to see if you have seen this before.

Thanks much in advance,
Prasad

just in case if someone else had this issue. please see below.

it was a classloader issue with weblogic, forced managed server to use libs in web-inf/lib folder via prefer-web-inf-classes tag
