  • Can I change the default variable delimiter in Freemarker?

    - by JamesD
    I am working on a project where I am generating some code/scripts (specifically Perl scripts) via Java and Freemarker. I have it working for now, but was wondering if there was some way to change the default variable delimiter ($) in Freemarker? Or is there a different Java template engine that would use a variable delimiter more suitable for generating a Perl script?

  • Why are there magic attributes exposed in the Servlet spec?

    - by Brabster
    It's always seemed a little at odds with the principles of Java that the Java Servlet Spec (2.5 version here) includes a set of magic attributes containing info about included resources, namely: javax.servlet.include.request_uri javax.servlet.include.context_path javax.servlet.include.servlet_path javax.servlet.include.path_info javax.servlet.include.query_string It's not even specifically pointed out in the API documentation, only in the spec where it is a must for correct implementation. This approach feels very wrong, an exposed implementation detail that clients will use and depend on. Why is this information exposed in this way?

  • Meaning of message "operations coalesced during safepoint"

    - by elec
    A java app runs with the following flag: -XX:+PrintSafepointStatistics, and then produces the following line on the standard output console: 2 VM operations coalesced during safepoint Anyone cares to explain what this mean ? More generally - is there a Java reference manual somewhere detailling all JVM flags, their use and, most importantly, the expected output, with relevant explanations ?

    - by Juliano
    I'm trying to bind a jar library (jCIFS) on MFA, but i'm stuck on some errors, like this one: 'Jcifs.Util.MD4' does not implement inherited abstract member 'Java.Security.MessageDigestSpi.EngineDigest() After some research, i found some topics about this, telling to edit the metadata to change the permissions of the classes, like this: <attr path="/api/package[@name='java.security']/class[@name='MessageDigestSpi']/method[@name='engineDigest']" name="visibility">public</attr> But the error didn't change, and a still won't get what this error means. Anyone ? Thanks.

  • Deep clone utility recomendation

    - by Supowski
    Is there any utility for deep cloning for java collections: Arrays Lists Maps NOTE: prefer some solution without usage of serialization, but with use of Object.clone() method.

  • Why maven requires so many options to create a hello world project,can you recommend a more dedicate

It seems that maven isn't satisfied to be just a Java build tool,but want to control all aspect of developing... Can someone recommend a really dedicated build tool for Java?

  • How to launch from Eclipse in Low priority under Windows?

    - by adum
    I'm running programs from Eclipse (on Windows) that eat a lot of CPU time. To avoid bogging down my whole machine, I set the priority to Low with the Task Manager. However, this is a cumbersome manual process. Is there a way Eclipse can set this priority automatically? EDIT: I realized that each particular launcher (Java, Python etc) has its own configuration method, so I will restrict this question to the Java domain, which is what I need most.

  • How do I make a rectangle move in an image?

    - by alicedimarco
    Basically I have an image loaded, and when I click a portion of the image, a rectangle (with no fill) shows up. If I click another part of the image again, that rectangle will show up once more. With each click, the same rectangle should appear. So far I have this code, now I don't know how to make the image appear. My image from my file directory. I have already made the code to get the image from my file directory. import java.awt.Color; import java.awt.Graphics; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.JPanel; public class MP2 extends JPanel implements MouseListener{ JFrame frame; JPanel panel; int x = 0; int y = 0; String input; public MP2(){ } public static void main(String[] args){ JFrame frame = new JFrame(); MP2 panel = new MP2(); panel.addMouseListener(panel); frame.add(panel); frame.setSize(200,200); frame.setVisible(true); } public void mouseClicked(MouseEvent event) { // TODO Auto-generated method stub this.x = event.getX(); this.y = event.getY(); this.repaint(); input = JOptionPane.showInputDialog("Something pops out"); System.out.println(input); } public void mouseEntered(MouseEvent arg0) { // TODO Auto-generated method stub } public void mouseExited(MouseEvent arg0) { // TODO Auto-generated method stub } public void mousePressed(MouseEvent arg0) { // TODO Auto-generated method stub } public void mouseReleased(MouseEvent arg0) { // TODO Auto-generated method stub } public void paintComponent(Graphics g){ super.paintComponent(g); // this.setBackground(Color.white); *Sets the bg color of the panel g.setColor(new Color(255,0,0)); g.drawRect(x, y, 100, 100); } }

  • apache httpclient and spawning a browser that will share the session

    - by Nick
    I'm have a java program that uses Apache httpclient api. This is used to login to and communicate to a webapp. Once logged in, there's a situation in which the program issues an execute process to open up firefox to hit the webapp and allow the user to see data in the browser. Since the java program is already logged in, is there a way to share that current session PHPSESSID so that the spawned firefox is already logged in and working in that same session?

    - by HJ-INCPP
    Hello, I have been working with java and python, so I found a nice web host which has support for these. But my question is, why can you find so hard such hosts? I understand that php is easy, I also understand that oracle host is hard to find ($$$ of course), but what do they have against some good open-source, completely free java spring, jsp, django, python, ror, perl etc etc .... So rare to find hosts ... not to mention freelancer bids Thank you.

  • google app engine proxy workaround

    I am trying to build a google app engine app in Java. The app is trying to get information from another site. On my computer I am behind a firewall and need to connect to the site through a proxy. Google app engine does not allow the use of java.net.proxy. Is there a way to configure eclipse so it knows that when I use URL.getContent() my local host will connect to that url through a proxy??

  • Why does C# not allow const and static on the same line?

    - by Cuga
    Why does C# not allow const and static on the same line? In Java, you must declare a field as 'static' and 'final' to act as a constant. Why does C# not let you declare const's as final? I make the further distinction that in Java, every interface is public and abstract, whether this is explicitly declared or not. Aren't const's effectively static in nature? WHy does C# balk at this?
