web services - JAX-WS Client Pool in a Java EE App Server -


I have an application running in a Java EE app server and it must call the web service of a partner company.

Using wsimport.exe from my JDK (1.6) I have generated client clients. I instruct the service to call the web service and receive the port.

I saw that the first call of the web service is slow and I believe it is because it is WSDL. The subsequent calls are fast.

I can keep WSDL locally, and apparently will accelerate the first call.

To customize my app, I was thinking that I pooled customers in this app, I have some throttling in the app - I think I have a pool of 5 clients, so I I'm using memory for up to 5 customers. If a sudden increase in my server increased, I do not have to worry that unlimited number of customers will be out of memory error. I believe, based on past experience, web service customers have used too much memory ...

  • Will you bother with the pool?
  • How will you get the web service slow on the first call?
  • What is the best way to create that pool, so that I have to do minimal programming (i mean a library / API / whatever, so that I can change the wheel again and some hairy bugs Do not have to code).

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
