<p><b><font size=+2>Q</font>.</b> <i>How do I create a Java array from
|
|
JavaScript?</i>
|
|
<p><b><font size=+2>A.</font></b> You must use Java reflection. For instance,
|
|
to create an array of java.lang.String of length five, do
|
|
<blockquote><tt>var stringArray = java.lang.reflect.Array.newInstance(java.lang.String,
|
|
5);</tt></blockquote>
|
|
Then if you wish to assign the string "hi" to the first element, simply
|
|
execute <tt>stringArray[0] = "hi"</tt>.
|
|
<p>Creating arrays of primitive types is slightly different: you must use
|
|
the TYPE field. For example, creating an array of seven ints can be done
|
|
with the code
|
|
<blockquote><tt>var intArray = java.lang.reflect.Array.newInstance(java.lang.Integer.TYPE,
|
|
7);</tt></blockquote>
|
|
|
|
<p><br><b><font size=+2>Q</font>.</b> <i>When I try to execute a script
|
|
I get the exception </i><tt>Required security context missing</tt><i>.
|
|
What's going on?</i>
|
|
<p><b><font size=+2>A.</font></b> You've likely missed placing the <tt>Security.properties</tt>
|
|
file in your class path at <tt>org.mozilla.javascript.resources</tt>.
