 <para>&Java; allows applications to be downloaded and run by a web
 browser, provided you have the necessary software installed on your
 machine. Many web sites make use of &Java; (for example, online
 banking services or interactive gaming sites). You should be aware
 that running programs from unknown sources could pose a threat to the
 security of your computer, even if the potential extent of the damage
 is not great.</para>
 
 <para>The check box <guilabel>Enable Java globally</guilabel> allows
 you to turn &Java; support on for all web sites by default. You can
 also select to turn &Java; on or off for specific hosts. To add a
 policy for a specific host, click the <guibutton>New...</guibutton>
 button to bring up a dialog in which you can type the host name and
 then choose to accept or reject &Java; code from that particular host,
 which will add the domain to the list on the left of the page.</para>
 
 <para>You can select a host in the list, and click the
 <guibutton>Change...</guibutton> button to choose a different policy for
 that host. Clicking the <guibutton>Delete</guibutton> button removes the
 policy for the selected host; after deletion, the global settings will
 then apply to that host.</para>
 
 <para>Finally, the group of controls labeled <guilabel>Java Runtime
 Settings</guilabel> allows you to set some options for the way in
 which &Java; should run.</para>
 
 <para><guilabel>Use security
 manager</guilabel> is normally enabled by default.  This setting will
 cause the <acronym>JVM</acronym> to run with a Security Manager in place. This will keep
 applets from being able to read and write to your file system, creating
 arbitrary sockets, and other actions which could be used to compromise
 your system. Disable this option at your own risk. You can modify your 
 <filename>$<envar>HOME</envar>/.java.policy</filename> file with the
 &Java; policytool utility to give code downloaded from certain sites
 more permissions.</para>
 
 <para><guilabel>Use KIO</guilabel> will cause the
 <acronym>JVM</acronym>to use &kde;'s own <acronym>KIO</acronym>
 transports for network connections.</para>
 
 <para>The <guilabel>Shutdown applet server when inactive for more than</guilabel>
 check box allows you to save resources by closing the &Java; Applet
 Server when it is not in use, rather than leaving it running in the
 background.  Leaving this disabled may make &Java; applets start up
 faster, but it will use system resources when you are not using a
 &Java; applet.  If you enable this, you can set a timeout.</para>
 
 <para>You can either opt to have &konqueror; automatically detect the
 &Java; installation on your system, or specify the path to the
 installation yourself by selecting <guilabel>Path to Java
 executable or 'java'</guilabel>. You may want to choose the latter method, for
 instance, if you have multiple &Java; installations on your system,
 and want to specify which one to use. If the &Java; Virtual Machine
 you are using requires any special startup options, you can type them
 in the text box labeled <guilabel>Additional Java
 arguments</guilabel>.</para>

 <sect2 id="kbrowse-javascript">
 <title>JavaScript</title>
 
 <para>Despite the name, JavaScript is not related at all to
 &Java;.</para>
 
 <para>The first part of this tab works the same as the &Java; settings.</para>
 
 <para>The checkbox <guilabel>Enable JavaScript globally</guilabel> allows
 you to turn JavaScript support on for all web sites by default. You
 can also select to turn JavaScript on or off for specific hosts. To
 add a policy for a specific host, click the
 <guibutton>New...</guibutton> button to bring up a dialog in which you
 can type the host name and then choose to accept or reject JavaScript
 code from that particular host, which will add the domain to the list
 on the left of the page.</para>
 
 <para>You can select a host in the list, and click the
 <guibutton>Change...</guibutton> button to choose a different policy for
 that host. Clicking the <guibutton>Delete</guibutton> button removes the
 policy for the selected host; after deletion, the global settings will
 then apply to that host.</para>
 <!-- missing section Debugging
 Enable debugger Enables builtin JavaScript debugger.
 Report errors Enables the reporting of errors that occur when JavaScript code is executed.
 How are errors reported? popup window? icon in status bar?
 -->
 <para>The final set of options in the section <guilabel>Global JavaScript 
 Policies</guilabel> determine what happens
 when a page uses JavaScript for specific actions.</para>
 
 <para>You can individually enable or disable the ability of JavaScript
 to manipulate your windows by moving, resizing or changing focus.  You
 can also disable JavaScript from changing the status bar text, so that
 for instance, you can always see where links will take you when
 clicked. The choices for these options are <guilabel>Allow</guilabel> and
 <guilabel>Ignore</guilabel>.</para>
 
 <para>For opening a new window, there is even more control.  You can
 set &konqueror; to <guilabel>Allow</guilabel> all such requests,
 <guilabel>Ask</guilabel> each time a request is made, or
 <guilabel>Deny</guilabel> all popup requests.</para>
 
 <para>The <guilabel>Smart</guilabel> setting will only allow
 JavaScript popup windows when you have explicitly chosen a link that
 creates one.</para>
