Subject RE: JCSAdminBean buildElementInfo problem -- how to get a list of keys in a region
Date Fri, 13 Jan 2012 16:07:00 GMT
Thanks a lot, Tim.   Yeah.  Thomas told me that.  So, I have posted it to users@commons
list yesterday.

I'll take a look into that jsp,and see whether that can help in some way.

You can take a look at the jcs admin jsp it might help

http://svn.apache.org/viewvc/commons/proper/jcs/trunk/src/java/org/apache/jcs/admin/JCSAdmin.jsp

Also this thread is dormant unfortunately.

It's been consolidated to one uber list for all of commons I think.

My final goal is to get a list of keys in a specified region.    then using that key to
get the details of a cache entry.

I tried to get back some details of a cache entry by the following snippet of code:

JCSAdminBean admin = new JCSAdminBean();
List elements = admin.buildElementInfo(myRegion);
System.out.println("There are a total of " + elements.size() + " items in the region");

I have over 100 cache items in the region "myRegion".    But the elements.size() always
returns 0.    WHY?   how can I resolve this?

By the way, I can successfully get back some region info by calling:
         List list = admin.buildCacheInfo(); 
and returns msg as below:

INFO: Cache Region - myRegion1
Cache Name: aerostat
Cache Type: 1
Cache Size: 0
Cache Misses (not found): 0
Cache Misses (expired): 0
Cache Hits (memory): 0
Cache Updates: 0
Cache Name: myRegion2
Cache Type: 1
Cache Size: 0
Cache Misses (not found): 0
Cache Misses (expired): 0
Cache Hits (memory): 0
Cache Updates: 0
INFO: There are 2 regions found

Any one has any clue on 2 questions:
1.) why does admin.buildElementInfo(myRegion1) not return any element info.
2.) why does the region info has 0s, even though I have tried to hit the cache many times?

Thanks so much for any insight on it.
