Change package names of java files

to shell java by ducleotide on Aug 15, 2008
changes the package names of java classes.

For example, if you have a bunch of java files in a package and you need to move them to a new package.

#!/bin/sh
                          
for file in `ls *.java` 
do
  sed -e "s/old.package.name/new.package.name/" $file > /tmp/tempfile.tmp
  mv /tmp/tempfile.tmp $file
done

To get past the problem of java programs showing up as grey squares on your screen when you are using a non-standard window manager, simply prefix the program name or "java -jar ..." with "AWT_TOOLKIT=MToolkit"

$HTTP["url"] =~ "^/tomcat/" {
  proxy-core.balancer = "round-robin"
  proxy-core.protocol = "ajp13"
  proxy-core.backends = ( "localhost:8009" )

Make your JSP an XHTML

to xhtml java jsp xforms by kemo on Aug 02, 2007
By default, a JSP file won't be considered as an XHTML stream by the web browser. This will make things such as XForms not being rendered since the browser XForms plugins/addons render Xforms only for XHTML pages. To make a JSP file as XHTML, put this at the beginning of the JSP file

<?xml version="1.0" encoding="utf-8"?>
<% response.setContentType("application/xhtml+xml"); %>


Note that the XML declaration has to be in the first line for a valid XHTML. Of course, after doing this, you need to make all your tags valid XML in your JSP as well.

How to use JSTL fmt:message and resource bundle

to java tomcat jstl jsp by kemo on Aug 02, 2007 2 Comments
To use JSTL fmt:message tags with a message bundle, there are two ways.

First, if there is only one properties file, use, the following code in web.xml file. 

  <context-param>
    <param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>
    <param-value>class.path.to.your.resources.bundle</param-value>
  </context-param>


Use <fmt:message key="your.message.key"/> in the JSP.

Second, if there are multiple properties files, and there are different locales, use
<fmt:setBundle basename="class.path.to.your.resources.bundle"/>

before <fmt:message key="your.message.key"/>

Or you can write

<fmt:bundle basename="class.path.to.your.resource.bundle">
  <fmt:message key="your.message.key"/>
</fmt:bundle>

Utilização de arquivo temporario em java

to java TempFile createTempFile by hfornazari on Aug 01, 2006
Gerar um arquivo temporario com extensao definida e retornar sua localização e nome, o prefixo para o nome do arquivo é temp.
retorno = null caso nao consiga criar o arquivo.
A criação será no local default da JVM.

  public String getTemp(String extension) {
    File f = null;
    try {
      if (extension == null) extension = ".tmp";
      f = File.createTempFile("temp", extension);
      FileOutputStream fi = new FileOutputStream(f);
      // salvo o arquivo recebido
      fi.write(getListFile().getBytes());
      fi.flush();
      fi.close();
      return f.getAbsolutePath();
    }
    catch (IOException e) {
