Re: long struts-config.xml file
If they used new HashMap(89) instead of just new HashMap(), the lookup would not change for 2000 objects at all because the HashMap growth beyond the initial size is ((2 times initial size) plus 1) which with 89 as the starting point keeps the size of the HashMap with a prime number well over 2000 providing no difference in lookup at that size.

Re: Re: long struts-config.xml file
Thanks Laurie for pointing that out. To validate an XML file, dtd or xsd defined order. This is an XML standard. I think one may create a new DTD (or even better a xsd ) that can separate different configuration files, while compatible with older version struts dtds. - Original Message - From: "Laurie Harper" To: user@struts.apache.org Subject: Re: long struts-config.xml file Date: Sat, 18 Jun 2005 23:20:35 -0400 > > Craig McClanahan wrote: > > Validation against the DTD requires two things: > > > > * Using the DOCTYPE declaration (as shown above) in the outer > > configuration file > > > > * Setting the servlet init parameter "validating" to "true" in > > /WEB-INF/web.xml > > for the Struts ActionServlet > > > > It doesn't matter whether you use XML entities or not. > > One note of caution: validation also requires complying with the > document order specified by the DTD, which can constrain the way > you break the file out into external entities (they have to > reassemble in valid document order). > > I'm not familiar enough with the DTD to know if this'll be a factor > for a struts-config.xml, or if Struts / Digester is sensitive to > document order (if you turn off validation). > > L. > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] Jack H.

Re: long struts-config.xml file
Good catch Laurie ... through at least today's version of the 1.3 DTD, it is indeed sensitive to the order of the elements. For example, all the elements need to be before the element that contains all the elements. Therefore, if you're going to use the XML entities approach, you'll need to create multiple entities for each logical segment ... one for the form beans, one for the actions, and so on. This was a lesson learned on the standards front ... in Servlet 2.4 and JavaServer Faces 1.0, the element order was defined to *not* be important ... that's something we could consider in Struts 1.3, because relaxing the restriction would not break any previously valid configuration file.

One note of caution: validation also requires complying with the document order specified by the DTD, which can constrain the way you break the file out into external entities (they have to reassemble in valid document order). I'm not familiar enough with the DTD to know if this'll be a factor for a struts-config.xml, or if Struts / Digester is sensitive to document order (if you turn off validation).

Re: long struts-config.xml file
Hi Frank, If you look at the link I provided you can see we had a pretty large project. I was working with a team working in multiple places in world. Maintaining and synchronizing struts-config.xml file did give us some bad time at beginning. So we choose the spirit of struts, MVC, but avoided this problem. We are working on an even larger project, so I had this question. >From beginning, I know performance was not a problem (see my previous posts). Maintenance was. For programming example, we like large C program becomes smaller pieces so application can be more managable. When struts becomes more mature and solve larger and more complex problems, we certainly may find some problems. That is the reason I propose this question. (I had some bad experience using a struts-based large web system. It was easy to see if a system was struts based if its URL showed something.do?) Hi Craig, Thank you for the link of Struts Console program. It looks better than the XML editor I used for struts before. Struts is a nice system. - Original Message - From: "Frank W.

Of course, there's also an XML level solution to this problem, something that works even if the program that is reading the document doesn't support multiple configuration files -- XML entities. Consider the following sort of struts-config.xml file: http://struts.apache.org/dtds/struts-config_1_2.dtd"; [ ... ]> &package-a; &package-b; ... where "package-a.xml", "package-b.xml" and so on contain the form beans and actions for some logical subset of your overall application. In this scenario, the XML parser glues everything together into one document (from the point of view of the application doing the parsing), while still allowing each subset's own configuration file to be managed by the team that is responsible for the code and JSP pages for that subset.

The largest Struts based configuration I've ever personally seen had
many hundreds of actions, and a similar number of form beans and so
on. They organized things with a separate configuration file for each
logical segment of the applicaton (independent of whether it was going
to be a separate Struts module or not). This wasn't done for
performance reasons; it was much more related to code management (the
config files for a particular logical segment should belong to the
developers working on that segment, with the overall application
architects exercising control over naming conventions to avoid
conflicts).

Re: long struts-config.xml file
The longest I have is 173 action mappings. I haven't noticed any performance problems with it. Struts basically loads it once at startup and from then on it's in-memory, so the only potential problem I could imagine is lookup speed, but that doesn't seem to be an issue. Breaking it up makes sense as others have said from an organizational standpoint. But, if your application doesn't make sense in multiple modules, and some don't, then it's probably not a big problem... be sure to have lots of comments in the config file and group things as logically as possible, much like writing any code!, and a few hundred shouldn't be an unmanageable number. -- Frank W.

Re: long struts-config.xml file
Yuniar and Nitesh, Thanks for replies. There are two possibilities struts could do with struts-config.xml. 1. load this file from server start up. save it in memory. or 2. read when it use it. The second possibility would have performance issue. So I assume struts use first possibility. The problem was maintenance. If a true large application (may have 500+ or even 1000+), the file become so complicated and easy to be messed up if one need add or change configurations. Maybe then have to separate by groups under webapps. Even so, many small groups are not convenient. So I thought someone may had this problem before and hopefully someone already deal with it. It is also strange that I did not find blogs or forums written by struts (but lots of phps). I think java is more powerful and can add a lot of more functionalities easier than phps. Jack H.

Re: long struts-config.xml file
There may not be a performance issue... probably could have some effect in startup (not sure if there are any though!) . Mainly this would be done to make your config files more 'readable' Also it makes sense to group the related ones together depending on functionality/module or whatever parameters that could separate/group actions/jsps/etc together.

RE: long struts-config.xml file
Hi Jack, You can split the struts-config module wise so that it is easy to handle. If you are having multiple struts config you should mention that as comma separated values in you web.xml. Eg: /WEB-INF/struts-config/common-config.xml,/WEB-INF/struts-config/A.xml, /WEB-INF/struts-config/B.xml etc. Hope this helps you Regards, Venkat -Original Message- From: Yen [mailto:[EMAIL PROTECTED] Sent: Friday, June 17, 2005 11:03 AM To: Struts Users Mailing List Subject: Re: long struts-config.xml file Is that possible, seperate the actions into modules and use the modules struts-config? - Original Message - From: "John Henry Xu" <[EMAIL PROTECTED]> To: Sent: Friday, June 17, 2005 12:04 PM Subject: long struts-config.xml file Hi all, In a project I am working on, we have a very lengthy struts-config.xml file to handle complex actions jsps (200+) take.

Re: long struts-config.xml file
depends on what version of struts u're working on. (i have never worked with 200 or so actions). :) 1) i reduced the number of actions using wildcards in action mapping, and a couple of hidden parameters that i pass to actions. kind of genericised the actions. 2) use "extends" where possible, mostly Actions and Forms, _especially_ Forms. 3) using extensions of dynaforms for my base forms (reduce dumb form beans. whats the name for these info containers? i forgot). bloats struts-config but reduces code to write. 4) while this may/will not :) reduce the size of struts-config, i've found this to be invaluable with large struts-configs. with struts 1.3 (in development), u might want to check out the new "key="key" value="value" /> - ability to set arbitrary properties. assists in genericising (eg: do something/somethingextra/nothing/differentthing in the called action base on some keyed property value) ... solves a lot of my pains :) riyaz John Henry Xu wrote: Hi all, In a project I am working on, we have a very lengthy struts-config.xml file to handle complex actions jsps (200+) take.
