  • Targeting Android with Scala 2.8 Trunk builds

    - by Kevin Wright
    The definitive reference for using Scala on android seems to be here: http://www.scala-lang.org/node/160 Unfortunately, all the references on using scala with android are based around Scala 2.7 and refer to a custom build android-library.jar, with a couple of cryptic references suggesting that this custom build isn't needed for later versions of android (I'm using 2.1 / API v7) So... What are the steps needed to use Scala 2.8 in an android project? Preferably using eclipse and the Android tools that Google supplies for that IDE.

  • How do you drop in substitute JRE classes?

    - by evilfred
    Hi, java.util.zip has well-known problems with native memory usage, so i'm trying to use a drop-in replacement called "jazzlib". unfortunately as is typical for sourceforge projects there is no documentation. If I add the jar to my classpath then Java freaks out and gives me "prohibited package name" errors because it replaced java.util.zip. How do I tell Java that this is what I want it to do?

  • Is there something like the OllyDbg / SoftICE disassembler + debugger for java?

    - by Ran Biron
    Is there a utility similar to OllyDbg / SoftICE for java? I.e. execute class (from jar / with class path) and, without source code, show the disassembly of the intermediate code with ability to step through / step over / search for references / edit specific intermediate code in memory / apply edit to file... If not, is it even possible to write something like this (assuming we're willing to live without hotspot for the debug duration)?

  • Failed to obtain JDBC Driver for MySQL under Tomcat environment

    - by Michael Mao
    Hi all: I've been trying to obtain the Driver class for JDBC connection to MySQL. The workstation is running on Linux, Fedora 10. I have manually set up the classpath variable for Java by CLI like this: bash-3.2$ echo $CLASSPATH /home/cmao/public_html/jsp/mysql-connector-java-5.1.12-bin.jar This shows that I've added the lastest mysql connection jar archive to my CLASSPATH variable. I've created a test JSP page which can be found here And source code for this page is: <%@page language="java"%> <%@page import="java.sql.*"%> <%@page import="java.util.*"%> <html> <head> <title>UTS JDBC MySQL connection test page</title> </head> <body> <% Connection con = null; out.print("Java version is : " + System.getProperty("java.version") + "<br />"); out.print("Tomcat version is : " + application.getServerInfo() + "<br />"); out.print("Servlet version is: " + application.getMajorVersion() + "<br />"); out.print("JSP version is : " + JspFactory.getDefaultFactory().getEngineInfo().getSpecificationVersion() +"<br />"); //out.print("Java classpath is : " + System.getProperty("java.class.path")+ "<br />"); //out.print("JSP classpath is : " + appliaction.getAttribute("org.apache.catalina.jsp_classpath") + "<br />"); //out.print("Tomcat classpath is : " + System.getProperty("org.apache.tomcat.common.classpath") + "<br />"); try { Class c = Class.forName("com.mysql.jdbc.Driver"); } catch(Exception e) { out.println("Error! Failed to obtain JDBC driver for MySQL... Missing class \"com.mysql.jdbc.Driver\"<br />"); } %> </body> </html> None of those commented out line would work, various Jsper Expetions would be thrown. You can check those Error pages from the following links: classpath Error page catalina Error page tomcat Error page It seems, from my limited knowledge of JSP and Servlet, the Tomcat environment "ignores" my Java CLASSPATH? In which case I cannot configure the MySQL JDBC package to let my Servlets(a JSP is but a Servlet anyway) work. I am not sure how to fix this issue. would it be better if I use an IDE like Eclipse or NetBeans and create a real Java "web app" so that everything can be "self-configured" by the usage of a web.config XML configuration file? So that I can certainly bypass this Tomcat environment restriction? Many thanks for the suggestions in advance.

  • taglib with constants functionality?

    - by jack
    I need to use some constants in my JSP. Now I'd like to use this without using scriptlets. (and adding getters is not an option, it's an external jar) Using the search I've seen that some people put them in a map. However I've seen that there's a constants function in the unstandard taglib but that is a few years old and so far I haven't found a maven repository with it. So are there any other taglibs with this functionality?

  • Unable to download jars using M2Eclipse (0.10.0, using Maven 3)

    - by DeepNightTwo
    I am using M2Eclipse (0.10.0, Maven 3)in projects. I can add Maven dependency using m2eclipse. But dependency jars couldn't be downloaded. Instead, it created a file in each local repo folder named [JAR_Name].jar.lastupdate. The content of this file is some thing like : http\://[REPO_URL]/central/=1276221188566 Even using Maven 3 command line. Jars couldn't be downloaded. Any idea about how could this happen?

  • Exploded (unpacked) EAR vs. Packaged EAR file?

    - by Adam
    In my office we use exploded EAR's (and inside them exploded WAR directories) for our test environments, and then a packaged one for production. I've yet to find a good explanation of the reason behind this though. I understand it's easier from a deployment perspective to push out a single file during builds, but it prevents us from doing things like property file changes without doing complete rebuilds (we could skip the compiles, but our environment currently binds the compile and jar processes together). What are the major advantages / disadvantages between these two configurations?

  • Creating a console in Java

    When I try to use java.lang.System.console(), I get a null pointer. I can still write to out and read from in, but this only works when I run straight from my IDE. When I run the .jar file directly, nothing happens. How can I create a console like I'd see using std::cout for use in Java?
