I am trying to set the max pool size value in *-ds.xml file. Currently the following approach fails as JBOSS always reads the max pool size as 0, - I would like to use <max-pool-size>${myapp.db.maxPoolSize}</max-pool-size> in myapp.ear/my-ds.xml  - It always ends up with maxPoolSize = 0 The following approach succeeds though, - If I use <max-pool-size>5</max-pool-size> in myapp.ear/my-ds.xml  - It ends up with maxPoolSize = 5 Any idea on why it doesn't read ${myapp.db.maxPoolSize} and always gets 0? and how I can fix it? I tried few suggestions mentioned in few discussion forums, but no success. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/817208#817208] Start a new discussion in IronJacamar at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
