java util package

[Chris Davies]

hi
i want to use the stringtokenizer class from the java util package but dont want to downalod j2se to do this - can anyone point me to a smaller jar file which contains the java util package as a downalodable jar, so that i can just put in my web-inf/lib file ?
cheers

StringTokenizer is part of the core Java APIs. By definition, if you're running Java code, it can "import java.util.StringTokenizer" and just use it. You don't have to download anything else.

[Layne Lund]

How are you programming in Java without a full version of the Java API available? What environment are you using? As Ernest mentions, you can just import the StringTokenizer class in order to use it. As part of the core Java API, it should already be available from within whatever development environment you are using.

thanks, i confused myself.
i'm trying to compile the file using the unix (os -sun solaris)command

 javac -classpath ".;$WEBTOP/../../lib/basisjdbc.jar;$WEBTOP/../../lib/basiswebtop.jar;$tom1/lib/servlet.jar;"
 -d $WEBTOP/../../classes $WEBTOP/../../../../examples/listclass/list.java 

but its giving me the following error

 error: cannot read: /../../../../examples/listclass/list.java   

here is the class

 import java.util.StringTokenizer;
import webtop.beans.legalist;
public class list
{
public static void main( String[] args )
{
// declares legalist constructor and assigns list variable
legallist ls = new legallist();
list = ls.getParameterNames();
String input = "list";
// remove those brackets
input = input.substring(1, input.length()-1);
// example use of StringTokenizer
StringTokenizer st = new StringTokenizer(input, ",");
while(st.hasMoreTokens())
{
System.out.println(st.nextToken());
}
}
} 

and an extract showing the structure of the api which the legallist comes from

 com.opentext.basis.webtop.beans 
Class LegalListBean
java.lang.Object
  |
  +--com.opentext.basis.webtop.beans.PageBean
        |
        +--com.opentext.basis.webtop.beans.LegalListBean
 

is it the end of the file or could the compiler error be anywhere in the compilation command ?

Given the error message, I'd say that "WEBTOP" variable is not defined, and so javac simply can't find your source file.

[Layne Lund]

The problem is that the javac command can't find your source file in the directory indicated. As mentioned, it looks like the WEBTOP variable isn't even defined. You can use the following command to see its value:

> echo $WEBTOP

If you just get a blank line, then the variable isn't defined. If you set the value yourself in .bash_profile be sure you also have a line with something like

export WEBTOP

You can have more than one variable listed in the export command.
Other than that, I've run out of guess about what you can do to fix the problem. Perhaps you can explain the directory structure of the location of your .java files.

thanks.
the problem was my directory structure - the $WEBTOP variable was defined in the .profile file (i'm running the korn shell).
now i'm getting the error follwing messages

 list.java:2: cannot resolve symbol
symbol  : class legalist
location: package beans
import webtop.beans.legalist;
                    ^
list.java:9: cannot resolve symbol
symbol  : class legallist
location: class list
legallist ls = new legallist();
^
list.java:9: cannot resolve symbol
symbol  : class legallist
location: class list
legallist ls = new legallist();
                   ^
list.java:10: cannot resolve symbol
symbol  : variable list
location: class list
list = ls.getParameterNames(); 

in the compilation command i specify the webtop.jar file which contains the class named legallistbean, this is then referenced in the list class by the command - import webtop.beans.legalist;
here is the class - i've changed the call to the LegalList class to the correct case but i can't see what else

 mport java.util.StringTokenizer;
import webtop.beans.LegalList;
public class list
{
public static void main( String[] args )
{
// declares legalist constructor and assigns list variable
LegalList ls = new LegalList();
list = ls.getParameterNames();
String input = "list";
// remove those brackets
input = input.substring(1, input.length()-1);
// example use of StringTokenizer
StringTokenizer st = new StringTokenizer(input, ",");
while(st.hasMoreTokens())
{
System.out.println(st.nextToken());
}
}
}
