JSP content downloads instead of rendering - upgrading JBoss 7 to wildfly

[Har P]

we are trying to migrate our application from JBoss as 7.1.1 final to wildfly. the server now renders the html files at the root context but any request for any of the jsp files ends up as a download of that jsp file instead of rendering.

I have tried the latest wildfly 11 and even 8.2.1 Final to go back a little but ends up with same behavior.

Is there something special that needs to be done for JSPs to work when we migrate from Jboss web to undertow(in wildfly). the only jsp config we have is in web.xml

that is

<servlet id="jsp">

     <servlet-name>jsp</servlet-name>

     <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>

     <init-param>

      <param-name>development</param-name>

      <param-value>false</param-value>

     </init-param>

     <init-param>

      <param-name>checkInterval</param-name>

      <param-value>400</param-value>

     </init-param>

</servlet>

Note: the application does use JSF 1.2 and richfaces-api-3.3.3.Final but these jsps have no jsf content, just plain jsps.

Can you attach a simple application which reproduces this on WildFly 11? Which operating system are you starting the server on and which Java vendor and version? Also, what exact URL do you use when you see this issue?

you do not need jsp servlet defined in your web.xml that is what container does for you.

It could be clashing with server provided jsp servlet.

Just remove it and its servlet-mapping and you should be fine.

If it still causes problems, please show whole web.xml and list of jars in WEB-INF/lib (you can omit yours)

Commenting out the jsp servlet info from web.xml brings up the welcome page jsps. Not sure how it was working on JBoss as 7.1.1 final and needed to be removed in wildfly 8.2.1 Final/wildfly 11.
