Re: Regexp utility classes..
I haven't tried these -- but here's a link to an existing package (that uses perl5-style regexps): http://www.win.net/~stevesoft/pat/

Hi, Syed,

Re: Swing: Can't find class ClassName
Since your class is inside a package, you'd need to refer to it this way:
java JFCBook.Chapter2.BasicFrame
(or get rid of the qualifying package name before compiling it)
Separately, do you have SWING_HOME set? (This may not be necessary under
Linux, but on Solaris and WinXX it is.)

Re: Slow loading on AMD Elan 486
The 1.1.7v1a JDK runs great on my AMD DX4-100 w/32Mb RAM. Since one can get something roughly 20x as fast as my machine for $500 these days, I'm not sure I understand why agonizing over the JDK's performance on a 486/33 is worthwhile. Linux itself, of course, will run great even on a 386/25 with 8Mb (I did this for a long time). But the JDK, particularly JDK 1.2 (a/k/a Java2), has a bit more bulk to it. JDK 1.2 for Linux arrives tomorrow (Thurs.), apparently. I can assure you it won't run well on a 486/33 -- but for a few bucks worth of hardware, you'll have a great JDK on a great OS. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: Java wrappers
You can use JNI (the Java Native Interface) to accomplish this.
a) your C/C++ functions have to be packaged in a shared library (which
you'd already anticipated)
b) the entry point for your C/C++ code has to use a Java
package-and-class-specific "mangled" name -- e.g., if your Java wrapper
class is "Wrapper" and that class is in package "Enclosure", you might have
a Java class such as:
package Enclosure;
public class Wrapper {
public Wrapper() {
// ...
}
// (only) declare in Java; implement in C/C++ code
public native String[] getKernelStuff();
}
which would result in a C function name for getKernelStuff() that includes
both the package and class names:
#include
JNIEXPORT jobjectArray JNICALL Java_Enclosure_Wrapper_getKernelStuff
(JNIEnv *env, jobject theObj) {
// ...
}
You can pass Java data types to your C code, and xfer/convert Java/C data
types in both directions.
Build your C/C++ code as a shared library, then load that library via Java
using the System.loadLibrary("shortLibName") function, as in:
public class TestTheWrapper {
public static void main(String[] argv) {
// this actually loads libWrap.so
// (name is platform neutral -- pre/suffixes
// are added implicitly
System.loadLibrary("Wrap");
Enclosure.Wrapper w = new Enclosure.Wrapper();
w.getKernelStuff();
}
}
