Hi,
I have a Enterprise java application and we are using Struts1.2 &
struts2-core-2.3.14.jar and everything is fine.
But now I want to use the Rest Plugin and I copied the rest plugin
(struts2-rest-plugin-2.3.14.jar) and made the below changes in the
Struts.xml file. Currently I am not using the Struts Convention plugin.
<constant name=*"struts.devMode"* value=*"false"*/>
<constant name=*"struts.action.extension"* value=*"xhtml,,xml,json,action"*
/>
<constant name=*"struts.mapper.class"* value=
*"org.apache.struts2.dispatcher.mapper.PrefixBasedActionMapper"* />
<constant name=*"struts.mapper.prefixMapping"* value=*"/rest:rest,:struts"*
/>
I haven't written any Rest Code yet. All the links are working.
But I get the below error in some of the JSPs(NullPointerException).
*java.lang.NullPointerException at
org.apache.struts2.dispatcher.mapper.PrefixBasedActionMapper.getUriFromActionMapping(PrefixBasedActionMapper.java:116)
at
org.apache.struts2.components.FormButton.evaluateExtraParams(FormButton.java:83)
at
org.apache.struts2.components.Submit.evaluateExtraParams(Submit.java:86)
at
org.apache.struts2.components.UIBean.evaluateParams(UIBean.java:876)
at
org.apache.struts2.components.Submit.evaluateParams(Submit.java:82)
at org.apache.struts2.components.ClosingUIBean.start(ClosingUIBean.java:55)*
That JSP has copule of submit buttons and below is the code.
*<s:submit type="button" label="Update Member Info"
action="updateRequestInformation" onclick="return
onCheckRequestInfo();" id="btnUpdMemberInfo" cssClass="cpslink">
</s:submit>*
When I remove the action attribute from the s:submit, I don't get the error
but when I add the action attribute I am getting the error.
I have lot of jsps which has lot of submit buttons with action attributes.
I was reading on the stackoverflow and some one suggested to override the
below constant in the struts.xml file but didn't help.
*<constant name="struts.mapper.action.prefix.enabled" value="true" />*
Please share your ideas. Is there a way other than changing the Struts
Submit button
Thanks
