Hi, I noticed that some users on the forum still don't get the advantages of using jax-ws instead of jax-rpc, so I tried to summarize them a bit and wrote them in the wiki. In case someone would like to fix something or contribute, the url is http://jbws.dyndns.org/mediawiki/index.php?title=JAX-WS_vs_JAX-RPC (you can reach this also from the FAQ). While writing that page, I found a performance analysis that compares jax-ws and jax-rpc using the Sun's WSTest project on Glassfish: http://java.sun.com/developer/technicalArticles/WebServices/high_performa... Do you think this also could be useful and might be linked in the comparison page? Actually I saw a page on the wiki about performance analysis, but as far as I see it's related to jbossws 1.2 only... Cheers Alessio
