Hi Di, I would like to ask you to register to the mailing list, so you are able to follow the mails that are exchanged. This will beneficial for you, because someone else might have encountered the same problem and a solution has already been provided by us or other users. You need to follow the instructions in the following site:
http://listes.epfl.ch/doc_en.cgi?liste=cloudsuite Regarding your question, try the following: a) Build the search agent according to the documentation, if you haven't done so. b) Use Java 1.6 and repeat the steps to set up the client. Please let us know if this solved your problem. Regards, -Stavros. ________________________________________ From: [email protected] [[email protected]] on behalf of di wang [[email protected]] Sent: Wednesday, March 28, 2012 8:33 PM To: [email protected] Subject: [cloudsuite] issues about running web search benchmark Hi, It is still me :) Since it is about another benchmark, so I started a new thread. I am trying to setup and run the web search benchmark. It all works fine for me (I can run curl "http://130.203.37.148:8080/search.jsp?query=google"; and it will give results say how many matches, etc) until I tried to use faban for running the benchmark. It mainly complains about java.lang.NoSuchMethodError ... , the error messages are in the following. My JDK version is 1.7.0 and ant version is 1.8.2. Any idea what went wrong?
