Thanks much for quick responses . Here I added more details.

We are not using maven-war-plugin . Also not using war file and web.xml file hence webfrag.xml is not merged into web.xml .

Our application uses jetty-web.xml file and all the precompiled pages (jetty-jspc-maven-plugin) are packaged into jar file along with other model classes for both versions 8.1.4 and 9.4.5

With Jetty version : 8.1.4 : we still seeing a /tmp/jetty-0.0.0.0-9010-webapp-_core-any-/jsp is getting created with 0 files under it. No issues seen.

With Jetty version 9.4.5 : We see /tmp/embedded-jetty-jsp/jsp/org/apache/jsp/pages is getting created with .class jsp pages. The issues we encountered is linux tmpwatch cron job is deleting these files older than 10days . when we access the portal later then the JSP pages are recompiled and located in /tmp location but the problem is we dont see all .class files are generated for all pages /tmp location though we navigate all the pages in portal. Hence we are getting IOException and no class defin found errors.

Error // this caused error due to only 2 folders were created with .class pages - not sure why it could not create other folders as listed below

[ ~]$ cd /tmp/embedded-jetty-jsp/jsp/org/apache/jsp/pages/

[]$ ls -lrt

total 8

drwxr-xr-x 2 xx xx 4096 Sep 7 19:16 product

drwxr-xr-x 2 xxx xx 4096 Sep 14 22:01 model

Expected : if tmp location has all these below folders then we dont encounter any errors

[/tmp/embedded-jetty-jsp/jsp/org/apache/jsp/pages]$ ls -lrt

total 28

Please help us on these.

1. why the jetty has recompiled only few pages as shown above when tmpwatch cleaned up /tmp folder ?

2. How to make sure the application uses precompiled jsps only and stop creating .class jsps in /tmp location ? I want application use only precompiled pages - without using web.xml file and war deployment model

Thank you

The embedded-jetty-jsp example project uses ServletContextHandler, not WebAppContext.
No WEB-INF/web.xml is in use that way.

We recently upgraded from Jetty version 8 to 9.4.6 ; The embedded Jetty server recompiling the JSP pages and creating a folder /tmp/embedded-jetty-jsp despite the configuration attribute Development is set to false.

In my lower env - the folder embedded-jetty-jsp is getting created and we see all the recompiled JSP pages .

in Production env - the folder embedded-jetty-jsp is getting created and we see ONLY few of the JSP pages are getting recompiled . Due to this we are getting below error on clicking the page in the portal - the page associated to jSP is recompiled in that tmp folder.

We need your help to find the rootcause and fix for this issue.
