I have been trying to install kosmos 0.2RC2 on Liferay 4.1.3 and Tomcat 5.20 on XP without success and have reached a brick wall despite reading all the manuals I can find. Much of which does not correspond to the files and directories I have. I have tried copying the liferay portal and server directories to tomcat webapps, but nothing happened, and the link in the reference to liferay hot deploy is invalid. I tried installing the generic .war download, and have had to edit the deploy files but have been able to build the .war file to install. however on deploy I get the following error: build: [mkdir] Created dir: C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\temp [unzip] Expanding: C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\kosmos-portlet.war into C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\temp [copy] Copying 2 files to C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\temp\WEB-INF [copy] Copying 1 file to C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\temp\WEB-INF\tld [delete] Deleting 1 files from C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\temp\WEB-INF\lib [copy] Copying 2 files to C:\Downloads\liferay\kosmos-0.2.0RC2\portlet\temp\WEB-INF\lib [replace] Replaced 16 occurrences in 16 files.
