    Servlet / Tomcat

    After the first use Tomcat has loaded the servlet into memory so it doesn't refer to your class file until you've reset. When developing, I find it easiest to keep a browser window open in the Tomcat Web Application Manager and click on reload to stop and start my session. Jeremy Nicholson...

    Sophisticated Shopping Cart

    You probably need a customised solution. If it were based on OSCommerce which is Open Source and free then the majority of your spend can go on the development itself. Jeremy Nicholson, System Architect http://www.PionLabs.com/

    Xalan and JDK1.4.1

    haven't used the Tomcat endorsed directory yet, but the one way to get xalan jars to be loaded in advance of the jre1.4 versions is to create an endorsed directory under jre/lib I sincerely hope that the Tomcat endorsed directory can do the same. Jeremy Nicholson, Director of...

    Multiple date dimensions

    The four differnt fields do all link to the same Time table, so that's how they would be shown in ErWin. However, as you say, when you do a SQL join you must use aliases of the Time table for each join. This is normally something for the programmer to work out an isn't expressed on an entity...

    IMAGE

    as you are using Sun One Studio it is probably looking for the image in the root directory of Sun One. Load images relative to a class resource, this will also allow you to put images into a jar file along with your classes. e.g. ImageIcon icon = new Imageicon(...

    Equals...

    ah, but I think that Hattusas is saying 'how can I compare the contents of two 2D arrays and say whether their contents are equal'....you could create a class containing an array and override the equals() method to check that 1) they are the same dimensions, 2) the contents of each cell are the...

    Connectivity with mysql and postgresql

    The MySql site has a download for Connector/J jdbc driver. Include it in your classpath and you will be able to access MySQL using jdbc. Look on http://jdbc.postgresql.org/ for the former.

    Same value in all objects

    test data

    I'm looking for a large chunk of data to test a system...preferably lots of information about individuals....something like a telephone directory would be ideal, but those CDs you can buy don't give me a database, only search access. Can anybody point me to a source of (free/low cost) test data...

    Dynamic Class Loading?

    a) yes b1) by writing your own ClassLoader b2) could influence startup speed, but I would think creating and destroying instances of classes would affect performance more. Unless you are really expert I would say, "Don't even go there!". this article...

    what is "Serializable"?

    There's no BeanInterface, so to officially become a bean you only have to follow the pattern of accessors and mutators (getters and setters), have a null constructor (so that an IDE could construct one for you) and make the class serializable (so that an IDE could remember the state and bring it...

    ...bit that says.... <!-- The mapping for the invoker servlet --> <servlet-mapping> <servlet-name>invoker</servlet-name> <url-pattern>/servlet/*</url-pattern> </servlet-mapping> .....as this is not turned on in Tomcat by default. ..and post in the right forum ;-) Jeremy Nicholson...

    Finding Postcodes

    If you've got lots of data and do this sort of query frequently you may consider adding a column for postcode area and programmatically keeping it populated. You could then index it and ask for customers where postcode_area in ('PE','NR','IP','E',etc.) and get the results back quickly. I...

    DBA's Duties and how to perform it?

    On a personal level, I think that your ultimate aim as a DBA is 'to make everything run so smoothly that people think that you don't do any work'......and 'to keep your head whilst everyone around you is losing theirs'. Jeremy Nicholson, Director of http://www.firstlightassociates.co.uk a...
