The system variables: JAVA_HOME, JBOSS_HOME, JWSDP_HOME and ANT_HOME are all OK. My Installation procedure are: I decompress jboss-4.2.0.GA.zip into "c:\jboss-4.2.0.GA" I decompress jbossws-1.2.1.GA.zip into "c:\jbossws" I decompress JBossIDE-2.0.0.Beta2-Bundle-win32.zip into "c:\eclipse" I put JWSDP into JWSDP 2.0 into C:\jwsdp-2.0 ...................................................................................... Into c:\jbossws I rename ant.properties.example in "ant.properties" I also modify "ant.properties" and uncomment the line below: jboss42.home=c:/jboss-4.2.0.GA I launch Ant from a console as below: ant deploy-jboss42 All is ok and Ant says build succesfully------ I test the JBoss installation with "http://localhost:8080/jbossws" and the page appears correctly. ....................................................................................
