Error deploying EJB on weblogic: Unable to set the transaction attribute

Question

Hi,
I'm trying to deploy an application in WL10.3.2 and an error occurred during activation of changes.
Here is the error message from the log file:

Please help me...Thanks.

In your ejb-jar.xml you are referring to a method saveActionGroup(EditableActionGroup) which is not defined in your remote interface.
Maybe you have made some typo in the configuration. Check your transaction section, i.e.,
<container-transaction>
            <method>
                <ejb-name>ViewBean</ejb-name>
                <method-name>saveActionGroup</method-name>
                <method-params>
                    <method-param>package.EditableActionGroup</method-param>
                </method-params>
            </method>
            <trans-attribute>Required</trans-attribute>
</container-transaction>or something similar. See if the defined methods are corresponding to the methods defined in the remote interface.
