Comment on Complete Apache 2.2-AJP Load Balance via mod_proxy by altuure

hi Joel,
it seems you have incompatible so module with your server library, be sure you get the same ‘so’ library version/build number with your apache version.

in most cases you need to build them all locally or get the whole distribution from one place.

Cheers

Hi guys, Thanks for the wonderful post here.
I have a problem to load mod_deflate .so. I get following error

Please help me on this.
Thanks in advance.

Hi,
I tried to use the subquery in the selection of criteria query. I am able to do it in JPQL and I tried to do the same using JPA criteria and it is saying “java.lang.IllegalStateException: Subquery cannot occur in select clause”. Is there a way to use subquery in selection or is there a way to join subquery to the main query using JPA criteria?

hi adi,
although depending on your requirements,IMHO writing to context folder is not a best practice

but in this approach since there should be only folder, you can use system property tomcat.server.port as a file prefix I guess ?

good luck

Hi,

It is a bit late but anyway…
How do you deal with file system resources? say the webapp writes to a file,
How this is going to work if I have 2 instances of this webapp running at the same time ?

Thanks
