Re: [Resin-interest] resin class reloading not working (3.1.19)

  Hi , this is my resin's init message :
  I grep no HotSwap keyword here ...

 Putting Spring aside for a moment, make sure the following is done:
 - compile resin.jni (./configure --prefix=/pathtoyourresin; make; make
 install)


Oops , I know what went wrong . I didn't compile resin.jni

Ogininally , I used resin as an apache module , and I 'thought' the 'make ;
make install' was to build the apache module.

But last year , I changed apache-with-resin-module to using
ProxyPass/ProxyPassReverse to redirect java requests to backend resin
server.
That's why I forgot to compile resin.jni ... :p

[Resin-interest] resin class reloading not working (3.1.19)

2009-12-22 Thread smallufo 
Hi :

I remember long long time ago , resin was (the only one that) able to reload
only the modified class , not the entire web-app. That was great !

But after I upgraded to some version (sorry , I forget what version , it is
long ago) , it didn't work anymore.

Today , I check again , 3.1.19 still reload all web-app even I modified a
String in println()  , (The class signature remains intact)

How to recall this feature now ?

Thanks.

I am not sure if you mean 3.1.9, but I checked with 3.1.9 and JDK 1.6.0_17 on 
windows – worked fine.

When resin starts serving first app it'll output either 

In-place class redefinition (HotSwap) is available.
or
In-place class redefinition (HotSwap) is not available.  In-place class 
reloading during development requires a compatible JDK and -Xdebug.

at the config level (by default the logging level is lower, so you'll need to 
change levels to see the message.

log name= level=all...

logger name=com.caucho level=config/

 How to recall this feature now ?

Actually it's log and logger

log name= level=all path=stdout: timestamp=whatever time stamp 
is/

and 

logger name=com.caucho level=config/


 But after I restart resin , I still cannot grep  any HotSwap  keyword in 
 jvm-default.log

The record should appear (once) when a class is loaded from WEB-INF/classes , 
so after first request to the page using it.

Also, resin jni should be compiled.

 Hi , this is my resin's init message :

Putting Spring aside for a moment, make sure the following is done:
- compile resin.jni (./configure --prefix=/pathtoyourresin; make; make install)
- change default resin.conf from
 log name= level=info path=stdout:
  timestamp=[%H:%M:%S.%s] {%{thread}} /
 logger name=com.caucho level=info/
to:
log name= level=all path=stdout:
 timestamp=[%H:%M:%S.%s] {%{thread}} /
logger name=com.caucho level=config/
- deploy a simple app into webapps with a jsp page and a class (simple webapp 
attached)
- start resin
- access the deployed webapp's index.jsp page with a browser (curl, wget)

After these steps you should see the following:

20:23:09.881] {main} Resin started in 1767ms
[20:23:28.011] {http--8080-1$22775072} Loading .tld files from global classpath

[20:23:28.946] {http--8080-1$22775072} In-place class redefinition (HotSwap) is 
available.

and after a touch on qa/Test.class and accessing the webapp again the following 
line will appear

[20:30:31.556] {http--8080-6$11446032} Reloading qa.Test

The resin.conf and webapp are attached.
