Subject [jira] [Commented] (GERONIMO-6295) Jsp is recompiled on each access
Date Tue, 06 Mar 2012 05:25:01 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-6295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13222999#comment-13222999

Jarek Gawor commented on GERONIMO-6295:
---------------------------------------

I updated the aries-testsuite/jsp test case to demonstrate the second issue (revision 1297340
and 1297341).

> JSPs are recompiled on each access under certain circumstances. 
> Jasper must be configured with development mode.
> There are two problems:
> 1) Bug 52744 (https://issues.apache.org/bugzilla/show_bug.cgi?id=52744) as discovered
by Forrest. This happens on file systems with time resolution of 1s (for example ext3 on Linux).
> 2) If JSP (in an WAB) uses tag files provided by another (separate) bundle, the generated
Java file for the JSP will contain the following dependent information (for example):
>   static {
>     _jspx_dependants = new java.util.HashMap<java.lang.String,java.lang.Long>(2);
>     _jspx_dependants.put("bundleentry://231.fwk1401888126/META-INF/tags/sharedTest.tag",
Long.valueOf(-1L));
>   }
> The problem is code checking the dependent timestamps in Compiler.isOutDated() does not
know how to deal with bundleentry:// urls and the code assumes the file is outdated (and needs
to be recompiled).
