How to Set environment variable ?

[Jack Dong]

Hi, sirs   the instructions of installing cocoon to tomcat4.0.4 below , that provided by apache group.   Build the Cocoon webapp as described above. Copy xml-cocoon2/build/cocoon/cocoon.war into tomcat/webapps directory. Set environment variable CATALINA_OPTS=-Djava.awt.headless=true Start Tomcat: Go to the tomcat/bin directory, and run the startup script. Open the Cocoon welcome page: http://localhost:8080/cocoon/ Congratulations! You should see the Cocoon welcome page. The third Step, I did not know how to do it and I use win2000 pro. Because it have three segments and in win2000 environment vairiable only has two segments, one is key and the other is value.   I did not do the third step, and I build cocoon has option target "installwar", and build sucessful. But when I browser httP://localhost:8080/cocoon/ , I got message below:   type fatal message SAX2 driver class org.apache.xerces.parsers.SAXParser does not implement XMLReader description java.lang.ClassCastException: org.apache.xerces.parsers.StandardParserConfiguration sender org.apache.cocoon.servlet.CocoonServlet source Cocoon servlet request-uri /cocoon/ path-info stack-trace java.lang.ClassCastException: org.apache.xerces.parsers.StandardParserConfiguration at org.xml.sax.helpers.XMLReaderFactory.createXMLReader(Unknown Source) at org.xml.sax.helpers.XMLReaderFactory.createXMLReader(Unknown Source) at org.apache.cocoon.components.language.markup.AbstractMarkupLanguage.generateCode(AbstractMarkupLanguage.java:377) at org.apache.cocoon.components.language.generator.ProgramGeneratorImpl.generateResource(ProgramGeneratorImpl.java:365) at org.apache.cocoon.components.language.generator.ProgramGeneratorImpl.createResource(ProgramGeneratorImpl.java:328) at org.apache.cocoon.components.language.generator.ProgramGeneratorImpl.load(ProgramGeneratorImpl.java:291) at org.apache.cocoon.sitemap.Handler.run(Handler.java:270) at java.lang.Thread.run(Thread.java:536) What wrong I did? cheers Jack Dong
