Each tiles:insert invokes ServletFilter
Hi,
I have a jsp page in which tiles:insert is called 10,000 times. I have 7 servlet filters defined in the application. My problem is that for each tiles:insert the entire filter chain is also invoked. This degrades my page rendering. I replaced the tiles:insert with out.println - in this case, the filter chain was not getting called and page performance improved dramatically.
I want a way to continue using filters and tiles, but avoid the filters being called for each tiles:insert.
I have to find a solution to this. Any help is appreciated.
Thanks,
Bhayzone

Bhay,
Before you spend much time on the current design, I suggest that you try
sending a page with dummy data to a browser that has 1000 rows and 10
columns. You might be able to demonstrate the lack of usability to the
customer and also uncover browser rendering issues with the design.

RE: Each tiles:insert invokes ServletFilter
Posted by Bhay Zone <bh...@yahoo.co.in>.
Lets assume that I have a 2-D array with the values. I display each cell using a tile. So if a number has to be dispalyed, we have a numeric-tile. Similarly We have a date-tile, we have a percent-tile etc. Using this approach, we maintain consistency in the data dispaly, for e.g we dispaly only two decimal places for all numeric data, All dates are displayed as mm-dd-yyyy. Do you get what we are trying to achieve with this tiles based approach? Now this tiles approach is used throughout the application (on all web pages). Making a change to this means changing almost all the pages. Now that will be huge in terms of effort and cost.
I was looking for a solution of the following lines:
The response gets flushed after/before each tile insert - thus invoking the filter. If I can avoid the response from being flushed each time, then maybe the filters will not get called. The tiles:insert tag has an attribute called as 'flush', which when set to false, does not flush the response. But doing that does not seem to be working for me. I also tried setting buffer="2700k" autoFlush="false" in the jsp page directive, but there was no change. Ran out of all tricks and so came here.
Thanks.

to replicate. Is it something you can lock down with a few site-wide
styles? It sounds like you have some flexibility so perhaps a different
view on that page layout might help the situation.

I tried to simplify the problem when I posted my question. Here is the
actual scenario.
Every piece of data displayed on my page is displayed using a tiles -
thats for uniformity across the application. There are around 1000 rows
being dispalyed, and each row has 10 columns (thus the figure 10k).
The business users want to see all the rows on one page. I really have to go
with the tiles / servlet filters thing. That's how the application was
written. It is beyond me to make those decisions. I have to find a way to
optimize the current page. Basically I need to find a way to stop the
filters being called for a tiles:insert. Once that happens, I should be on
my way.
