Re: Cannot find bean in scope null
You need to instantiate the bean in the action class and store in request object.

Re: Java Website ISP
Host at home and install the latest/greatest with whatever db you want. Thats my preference. I have seen most of the ISP supporting older versions and expensive. If you have dynamic ip check out easydns.com or search google for dynamic ip hosting At 10:25 AM 6/7/2002 -0400, you wrote: I fired my ISP yesterday for refusing to support server-side Java and am now actively looking at alternatives. I was surprised to find that there are only about 70 ISPs in the US supporting server-side Java. The good news is that most use Tomcat 3.2 on Apache and support JDK 1.3.1, Servlet 2.2 and JSP 1.1 with access to MySQL, and all that I have contacted are planning to upgrade to Tomcat 4.0x, JDK 1.4, Servlet 2.3 and JSP 1.2 within the next 8 weeks. One (SpinWeb.com) even will let you upload your own versions of Tomcat and JDK. The bad news is prices range from $350/year to $750 and I have no qualitative anecdotes regarding the level of service any provide. If anyone has first-hand knowledge of same, I'd appreciate the information. I want to make a decision in the next couple of hours so I can (hopefully) get the new DNS IPs propagated by tomorrow night.

Re: Multiple search on single page - approach
Dont think that is a good idea to have 1 values in a list. If you can avoid it, you can try the navigation tag as another user suggested. Dont think its a good idea to use Javascript with this amount of data either. Best is if you can add one more search criteria in addition to id to narrow search results. At 01:58 PM 6/5/2002 -0700, you wrote: Hello All, I have single page ( JSP) which has multiple (5) search criteria where user enters corresponding ids . User can eneter id's and onchange event populates the corresponding drop down lists. Lists are popultaed from DB so there is server trip for every onchange event. Page refreshes every time. I am looking forward to implement some thing simple which will avoid multiple trips to server so that single server submit can help. Drop downs still needs to be populated from DB and has more than 1 records. Are there any other good approaches ? thanx in advance __ Do You Yahoo!?

Re: servlet context/Action class - performance question.
We store much more information that in our application context and dont have any performance issues. We store all our master data (static) on startup. The performance is enhanced. Again it depends on how much data you have and how much it is supposed to grow over time. That you should consider. At 01:01 PM 6/3/2002 -0500, you wrote: The requirement is to display a page with some categories just like the yahoo homepage. The link of each main category will have to show the subcategories of that category in a similar page. The level of this tree goes one more level inside. All this information is built ofcourse by retrieving from the database. First thought was to build the relevant section of the category/subcategory tree based on the request parameters. Since these pages are going to be the most viewed (and does not change based on the user), I thought it would be better for performance if the whole tree is created in a startup servlet and put in servlet context instead of creating a part of it in the Action class and setting it into the HttpServletRequest. This would mean that I wont have to hit the database for every user request. I will just have to get the relevant part of the category tree from the (big) object in servlet context based on a key lookup on the TreeMap. The pages load surely very fast, ~but~ I am wary of such a big object in memory and its effect on the performance once it goes into production. To give a rough idea about the size of this tree: 1 main category (TreeMap) has about 12 subcategories (TreeMaps again). Each of the subcategories has about 10 child categories. Each child category is a ArrayList of strings. So its a TreeMap of TreeMaps of ArrayLists. Did anybody face similar design choice and had to choose against a setting so much information in the servlet context? Any input is greatly appreciated! I apologize for the subject being a little off-topic.

Dont know if this will work Try using IMG SRC=URL instead of regular button with the URL having a different query string for edit and continue. eg ...?action=edit At 02:26 PM 6/3/2002 -0400, you wrote: Hi guys, I'd like to know if there is a way that I will know which button was pressed.

Re: Pros and Cons of Struts
referring to the four taglibs - bean, html, logic and template we make use of all. All work very nice. thats the pro. For cons, i think these taglib's can make the app slower since there are now more classes being instantiated/re-used compared to using straight scriptlets or html.
