Is this a good coding practice of making a jar file of an ADF application and then placing it in main ADF application. (its like presence of customed developed jar files inside a war file)
I believe that it will cause severe memory issues on server but i can't find requisite link or source which states that it should be avoided.
We are also using the same practice and same is mentioned in Oracle docs, It increases the reusability of application. I don't think that it'll cause memory issue but yes there are connection pool issues sometimes.
