• Compute jvm heap size to host web application

  - by Enrique

  Hello, I want to host a web application on a private JVM they offer 32, 64, 128, 256 MB plans. My web application uses Spring. And I store some objects for every logged in user session. My question is: How can I profile my web app to see how much heap size it needs so I can choose a plan?, How can I simulate hundreds of users logged in at the same time? I'm developing the application using Netbeans 6.7 Java 1.6 Tomcat 6.0.18 Thank you.

• Pattern for creating a database schema using JDBC

  - by Space_C0wb0y

  I have a Java-application that loads data from a legacy file format into an SQLite-Database using JDBC. If the database file specified does not exist, it is supposed to create a new one. Currently the schema for the database is hardcoded in the application. I would much rather have it in a separate file as an SQL-Script, but apparently there is now easy way to execute an SQL-Script though JDBC. Is there any other way or a pattern to achieve something like this?

• UnsupportedOperationException on Collection

  - by Duke Vador

  While studying the Collection API, we find that some methods (add, remove,...) may throw a java.lang.UnsupportedOperationException if the current implementation of the Collection does not support those functionalities. Is there,actually, in the JDK, a concrete Collection that does not support those methods ? Thanks a lot for your answers.

• Android Calendar API vs Calendar Provider API

  - by John Roberts

  I'm a little bit confused about the difference between the two. An example of the Calendar API is supposedly located here: http://samples.google-api-java-client.googlecode.com/hg/calendar-android-sample/instructions.html, but the author himself suggests using the Calendar Provider API, details about which are here: http://developer.android.com/guide/topics/providers/calendar-provider.html. Can someone explain to me the difference between the two, and which would be better for me to use for a simple calendar app?

• Is it safe to use connection.createStatement().executeQuery(String query);?

  - by javanix

  Is it safe to do connection.createStatement().executeQuery(String query);, or should each java.sql.Statement object be created and closed by "hand" on every use, even if the connection is closed in a finally block? If multiple queries are executed in one method by one connection it would use much less code if instantiating and closing each statement wasn't strictly necessary.

• Passing JSON through the URI

  - by Leaf

  I'm trying to create a REST based web service with data encapsulated using JSON. My problem is when I pass the string version of JSON in the URI it turns to something like this: %7B%22coal%22:100,%22ele%22:1500.1%7D. I'm wondering if there are any functions Java for converting between the escaped and unescaped versions so I can parse the string.

• Is MobiForms for Android worth investigating ?

  - by Alan B

  I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?

• Graceful way to exit a dm_job ? System.exit()?

  - by Ayrad

  If I want to properly exit a documentum java job (if params are invalid for example), should I use a system.exit() or is there another way to do it. As far as I know system.exit closes the virtual machine, does it have an effect on other jobs running?

• What is the recommended way to set GET parameters on a Restlet request?

  - by Simon Nickerson

  What is the recommended way of setting GET query parameters on a Restlet Request object? I think I can see how to get them out of the request using getQueryAsForm(), but how do they get set in the first place? At the moment, I am adding them manually to the URL using a StringBuilder and java.net.URLEncoder, but it seems like there should be a better way.

• Is it possible to create a DateFormatter which converts a two-digit year into a four-digit year?

  - by DR

  In my Java application I use a DateFormat instance to parse date inputs. DateFormat fmt; fmt = DateFormat.getDateInstance(DateFormat.DEFAULT) // dd.MM.yyyy for de_DE The problem is that the user insists to enter dates in the form 31.12.11. Unfortunately this is parsed to 31.12.11. (0011-12-31 in ISO format) Instead I want the parsed date to become 31.12.2011 (2011-12-31 in ISO format). Can I modify the date format to somehow parse inputs that way?

• Formatting a long timestamp into a Date with JSTL

  - by scubabbl

  I am pulling a long timestamp from a database, but want to present it as a Date using Tags only, no embedded java in the JSP. I've created my own tag to do this because I was unable to get the parseDate and formatDate tags to work, but that's not to say they don't work. Any advice? Thanks.
