no class def found when using regexp

[jtnews <jt...@bellatlantic.net>]

I'm having problems. I'm not sure why...if someone can give me a
clue.....

first I built the jar file with

export JAVA_HOME=/usr/java/jdk1.3 && sh build-regexp.sh

Then I compiled the following simple test program....

import org.apache.regexp.*;

class RegexTest {
    static void main(String [] args) throws Exception {
        int i = 0;
        String regex = args[i++];
 for (;i < args.length; ++i) {
     String string = args[i];
            System.out.print("RE(\"" + regex + "\").match(\"" +
                      string + "\")=");
            RE r = new RE(regex);
            if (r.match(string))
  System.out.println("true");
            else
                System.out.println("false");
        }
    }
}

Then I compiled with......

javac -g -O -classpath .:/sw/java/lib/jakarta-regexp-1.1.jar
RegexTest.java

Then I ran with....

export LD_LIBRARY_PATH=.:/sw/gcc/2.95.2/lib && java RegexTest "aa*.*"
"alpha"

and got....


RE("aa*.*").match("alpha")=Exception in thread "main"
java.lang.NoClassDefFoundError: org/apache/regexp/RE
 at RegexTest.main(RegexTest.java:11)

Can someone send me a small example?
Thanks.

Not exactly - 

-classpath and CLASSPATH are interchangable (mostly, see the docs for
details).  But yeah, you have to always say the classpath, whether
compiling or running the VM.

Ok, I know what I did wrong, I have to specify both -classpath on the compile line
AND
CLASSPATH when I run java.  I thought it was one or the other, but you have to do
both.

Thanks!

no. javac just is for compiling. you still need to put your .jar's into your
execution classpath. java doesn't static compile stuff.

The LD_LIBRARY_PATH is there to load a shared library from a
JNI. javac -classpath .... is supposed to take care of the classpath
issue.  I tried CLASSPATH too but that didn't work either.

Why are you putting gcc into your LD_LIB_PATH? You need to put the
jakarta-regexp-1.1.jar into your CLASSPATH.
