RE: JSP Compilation Issues (Multiple Domains)

2002-10-01 Thread John Trollinger 

Can we get the sync changes in the 4.1.x releases as we also have
problems with this and currently maintain our own jasper code base with
the sync code in it.

 problem that the javac not being thread-safe.
 
 In Tomcat 5 the javac compilation is synchronized, so that 
 the compilation is serialized.  Guess that fix is not ported

 I always assume that JSP pages would be deployed precompiled, 
 and simultaneous compilation under development mode is rare.  
 Maybe my assumption is wrong?

  Hi All,
  
  I'm currently running multiple domains (2 specifically) on top of 
  Apache/Tomcat.  It seems that when I hit both domains at 
 the same time 
  (using 2 browser windows), I get a JSP compilation error 
 most (85%) of 
  the time.
  
  However, when I reload the page with no JSP code change, 
 it'll compile 
  properly.  (Some of the time like 10-15%, it won't 
 recompile until I 
  touch the file manually)
  
  Note: It doesn't happen when I only access one domain.
  
  PROBLEM SUMMARY:
  When loading JSPs on multiple domains (hosts) simultaneously, a JSP 
  compile error is generated.
  
  SYSTEM COMPONENTS:
  - Solaris 2.8
  - JDK 1.4.0_01
  - Tomcat 4.1.12
  - Apache 1.3.20
  
  SOLUTIONS TRIED (FAILED):
  - Configured different workers for each domains (hosts) as 
 recommended 
  in the tomcat mod_jk document.
  - Downloaded the source of tomcat and recompiled everything on our 
  environment.
  
  Any help would be appreciated.
  
  Thanks.
  
  Best regards,
  Joseph Kiok

Re: JSP Compilation Issues (Multiple Domains)

2002-10-01 Thread Glenn Nielsen 

Another way to fix this would be to install the external compiler jikes and
configure Jasper 2 to use this.

I would also like to see a servlet init parameter added to jasper that can enable
or disable synchronized JSP compiles.  This way those who know they have a thread
safe way to compile JSP's don't get hit by the synchronize.

Regards,

Glenn
