How to externalize properties of persistence.xml for JBOSS 7.1.1?

由 筅森魡賤 提交于 2019-12-06 16:28:29
My persistence.xml is currently present in the application war(in META-INF folder.). However, for the application to be run across multiple DBs the persistence needs to be changed again and again. I want to avoid it. But, I am not able to understand how will i configure the properties(like dialect) in the persistence.xml from, say, a property file which i would change based on my DB, hence not compelling me to update and redeploy my war. My problem can also be resolved if i can configure the dialect in the datasource in standalone.xml where i have mentioned other DB details. I am not being

Modularization of Jasper reports: Pass data source to subreport without unnecessary db roundtrips?

由 我的梦境 提交于 2019-12-06 15:54:14

It seems that this may be my problem because the report is always generated (without an error) ... ok: using the connection from the master report (thus each time executing the query

What's the most efficient way to handle a UIButton Photo Grid in a UITableView?

由 陌路散爱 提交于 2019-12-06 14:52:53
问题 I have an iOS app I'm working on that grabs a bunch of photo URLs from a MySQL database with a JSON request. Once I have these photos and related information, I use it to populate the datasource for a UITableView. I want to create a grid of UIButtons, made out of photos, 4 per row. This current code works, however it is wildly slow and my phone / simulator freezes right up as I scroll through the table. Tables with only a couple rows work fine, but once I reach 10 or more rows it slows right
