same problme with http://wiki.jboss.org/wiki/attach?page=JbpmBpelDesigner%2FJBossBPEL_Designer_GettingStarted.pdf
i think its because the author of this wiki has an eclipse project with the .classpath an .project files from eclipse, so he or she can import it in eclipse with "Existing Project into Workspace"
but if you download the jbpm-bpel-1.1-Beta3.zip file you dont get this .classpath and .project files, so you cant import it like the wiki say
(maybe i am wrong?)
i try to import it with New-> Java project -> Create project from existing source, but then eclipse show me a lot of errors and i dont know why
maybe somebody will help or tell us how to import it in eclipse without the eclipse project files and without errors ? ;)
