Concurrent Access for Crystal Reports for eclipse

Question

Hi,
May i know is there any concurrent access limitation when viewing the reports in web using JRC?

Answer 1

The performance does get better after the initialization of the JRC application.  Because it is a pure java application without any reliances on servers for processing power, it will rely on the speed of the application server.  In the initialization, all of the libraries get loaded in to the classpath so this does take some time.  Generally speaking the performance will get better after this because everything has been loaded in to memory; that is until you restart the application server.
The JRC will be a bit slower when rendering a large report.  Depending on the size of that report, you may be looking at between a few seconds and several minutes in processing time.
Whether or not you use the JRC will depend on the number of users you anticipate having at any given time for your application as well as the general size of your reports.
Crystal Reports Server comes with a set number of licenses.  Initially it comes with 5 and you can purchase up to 20 or 25.  This means you could potentially have about the same number of users as you would with a JRC application, but if you have large reports then you could take advantage of the benefit of being able to schedule those reports (set them to run during an off time so your users can view the instances quickly when they need to).  You do have to be more mindful of how you use licenses with this product, since for each user logged on to the system there will be a license used.  There are many additional benefits, including performance that can be had with CR Server.  One key difference would be in the cost of the product:  The JRC is essentially free, whereas CR Server is not. 
I would suggest reading our product documentation and applying it to your situation to determine what implementation would work best for you.
