CATS Setup - Lab #1 - XML Parsing

If you are performing this assignment on the CATS machines, you need to perform the following setup steps before starting your work:

1. Make sure you're using the most recent version of the Java SDK running on the CATS machines by adding /usr/local/java/j2sdk/bin into your PATH environment variable. This can be accomplished by adding the following line to the end of your .cshrc file (located in your home directory):
   
   

   set path=(. /usr/local/java/j2sdk/bin $path )

2. Load these changes into your active shell:
   
   

   unix> source .cshrc

3. Verify the changes were made:
   
   

   unix> printenv PATH
   
   .:/usr/local/java/j2sdk/bin:/local/bin:/usr/afsws/bin:/...

4. Now add the Xerces parser into your CLASSPATH environment variable. This is done by adding the following lines to the end of your .cshrc file.
   
   

   setenv XERCES /afs/cats.ucsc.edu/class/cmps183-jw.s03/xerces-2_4_0/
   setenv CLASSPATH .:$XERCES/xercesImpl.jar:$XERCES/xercesSamples.jar:$XERCES/xmlParserAPIs.jar

   
   
5. Load these changes into your active shell:
   
   

   unix> source .cshrc

6. Verify the changes were made:
   
   

   unix> printenv CLASSPATH
   .:/afs/cats.ucsc.edu/class/cmps183-jw.s03/xerces-2_4_0/xercesImpl.jar:
        /afs/cats.ucsc.edu/class/cmps183-jw.s03/xerces-2_4_0/xercesSamples.jar:
        /afs/cats.ucsc.edu/class/cmps183-jw.s03/xerces-2_4_0/xmlParserAPIs.jar

7. Verify that Xerces is set up correctly by running a sample program that comes with the Xerces distribution:
   
   

   unix> cd $XERCES
   unix> java sax.Counter data/personal.xml
   data/personal.xml: 148 ms (37 elems, 18 attrs, 140 spaces, 128 chars)

   
   (Note that the execution time reported--the value before the "ms"--will vary, but the other values should match exactly. Also note that the upper case "C" is important in sax.Counter above.)
