OK sorry missed the not.
Although I am mapping in post resources to a maven project which has a
resources folder that ends up in the target/classes folder.
<PostResources
base="/home/devuser/git/mavenproject/myplugin/target/classes"
className="org.apache.catalina.webresources.DirResourceSet"
webAppMount="/WEB-INF/classes" />
ie
/home/devuser/git/mavenproject/myplugin/src/main/resources/template/..
WARNING: Unable to add the resource at
[/WEB-INF/classes/template/js/jstree/jquery.hotkeys.min.js] to the cache
for web application [/myapp] because there was insufficient free space
available after evicting expired cache entries - consider increasing the
maximum size of the cache
Nov 07, 2023 6:22:52 AM org.apache.catalina.webresources.Cache getResource
Checking the logs, it only complains about /WEB-INF/classes/
I will test and calculate the size of all the target/classes folder
which are mapped under /WEB-INF/classes in post resources.
Cheers Greg

Since I have nothing in either of these, its all mapped in the
PostResources, I can just calculate the size of the jars, and add a
bit for luck. (ie 85mb +5mb).🙂
The "i.e. everything NOT under WEB-INF/lib or WEB-INF/classes" is
irrespective of which resource collection it is in. So JARs from
PostResources won't be cached.

Thanks

I have not noticed any slowness yet.
There are alot of jars (approx 160), but the target/classes folder
are my
app's classes that I am working on. These can change (ie not
static), so
may be better to switch it off.
Is there anyway to calculate the size needed for the cache setting?
The maximum useful size will be the total size of static resources
(i.e. everything NOT under WEB-INF/lib or WEB-INF/classes).
The right size is going to be a trade-off between the cost of the
memory for the cache and the benefits the cache brings. Those
benefits are going to be application (and hardware) dependent.
Mark
Thanks Greg

OK thanks, the docs mention "static resource cache" but I could not
find info on what it actually is.
It caches the content of static resources in memory and uses that
rather
than accessing disk.
I am loading maven jars and /target/classes.
eg:
<PostResources
base="/home/devuser/git/myproject/tools/META-INF"
className="org.apache.catalina.webresources.DirResourceSet"
webAppMount="/WEB-INF/classes/META-INF" />
<PostResources
base="/home/devuser/git/myproject/target/classes"
className="org.apache.catalina.webresources.DirResourceSet"
webAppMount="/WEB-INF/classes" />
<PostResources
base="/home/devuser/.m2/repository/commons-logging/commons-logging/1.2/commons-logging-1.2.jar"
className="org.apache.catalina.webresources.FileResourceSet"
webAppMount="/WEB-INF/lib/commons-logging-1.2.jar" />
As its purely for development guess it makes no difference?
I doubt you'll notice if you disable it.

Since you are using JAR files, the caching won't matter once the
classes
themselves are loaded-into memory. So you may observe some slowness
early in the lifetime of the web application after deployment, but at
long as your code, etc. isn't trying to re-scan JAR files all the
time,
etc. then you should be fine.

Hello,
I am using the <Resources> and <PostResources> to run tomcat for
debugging my app (and it is pretty awesome). I am getting the
cache
warning limit, as it is 10mb, what effect would it have if I
turned
off the cache ie cachingAllowed="false" rather than having to
increase the limit all the time?
This is one of those "it depends" questions. There are lots of
factors that will influence how effective the cache is. You
could try
and reason what the impact would be but you will likely get a more
accurate answer, faster by just trying it and measuring the
impact.
