Error number 3202 in 3: Exception while reading document XWiki.XWikiPreferences Wrapped Exception: could not load an entity

Hi I have some issues impeding me to test the latest svn version of xwiki. Do you know a fix? I want to run xwiki with jetty/hsql using xwiki_start.sh. I started my investigations by downloading the freshest xwiki version on svn. For the rest of the story I am using Eclipse, where I imported the project and I specifed the sources I just downloaded. So far so good. tips - I had to manually add junit from the /lib directory to ant classpath (run as would always complain about a missing junit class for the cactus target. Now I can run ant targets. I find the "standalone" target and I run it. It unzipped the release of jetty stored somewhere (above) and copied the xwiki files under webapps. That's fine. I find the script/batch_files to start the wiki, and so do I. Apparently the database is created but it stops there. I get the following message in the browser: --- HTTP ERROR: 500 Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3202 in 3: Exception while reading document XWiki.XWikiPreferences Wrapped Exception: could not load an entity: [com.xpn.xwiki.doc.XWikiDocument#104408758] --- and then in the logs: --- 02:15:05,297 ERROR P1-19 http://lijour:8080/xwiki/bin/view/Main/WebHome GraphVizPlugin:init:90 - Cannot find graphiz dot program at c:/Program Files/ATT/GraphViz/bin/dot.exe 02:15:05,298 ERROR P1-19 http://lijour:8080/xwiki/bin/view/Main/WebHome GraphVizPlugin:init:99 - Cannot find graphiz neato program at c:/Program Files/ATT/GraphViz/bin/neato.exe 02:15:05,848 WARN P1-19 http://lijour:8080/xwiki/bin/view/Main/WebHome JDBCExceptionReporter:logExceptions:71 - SQL Error: 0, SQLState: null 02:15:05,849 ERROR P1-19 http://lijour:8080/xwiki/bin/view/Main/WebHome JDBCExceptionReporter:logExceptions:72 - Borrow prepareStatement from pool failed 02:15:05,850 WARN P1-19 http://lijour:8080/xwiki/bin/view/Main/WebHome JDBCExceptionReporter:logExceptions:71 - SQL Error: 0, SQLState: null 02:15:05,851 ERROR P1-19 http://lijour:8080/xwiki/bin/view/Main/WebHome JDBCExceptionReporter:logExceptions:72 - Borrow prepareStatement from pool failed com.xpn.xwiki.XWikiException: Error number 3202 in 3: Exception while reading document XWiki.XWikiPreferences Wrapped Exception: could not load an entity: [com.xpn.xwiki.doc.XWikiDocument#104408758] at com.xpn.xwiki.store.XWikiHibernateStore.loadXWikiDoc(XWikiHibernateStore.java:462) at com.xpn.xwiki.store.XWikiCacheStore.loadXWikiDoc(XWikiCacheStore.java:157) at com.xpn.xwiki.XWiki.getDocument(XWiki.java:819) at com.xpn.xwiki.XWiki.getDocument(XWiki.java:850) at com.xpn.xwiki.XWiki.getPrefsClass(XWiki.java:1854) at com.xpn.xwiki.XWiki.initXWiki(XWiki.java:590) at com.xpn.xwiki.XWiki.<init>(XWiki.java:504) at com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:248) at com.xpn.xwiki.XWiki.getXWiki(XWiki.java:336) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:98) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:596) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:428) at org.mortbay.jetty.servlet.WebApplicationHandler$CachedChain.doFilter(WebApplicationHandler.java:830) at com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:127) at org.mortbay.jetty.servlet.WebApplicationHandler$CachedChain.doFilter(WebApplicationHandler.java:821) at org.mortbay.jetty.servlet.WebApplicationHandler.dispatch(WebApplicationHandler.java:471) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:568) at org.mortbay.http.HttpContext.handle(HttpContext.java:1565) at org.mortbay.jetty.servlet.WebApplicationContext.handle(WebApplicationContext.java:633) at org.mortbay.http.HttpContext.handle(HttpContext.java:1517) at org.mortbay.http.HttpServer.service(HttpServer.java:954) at org.mortbay.http.HttpConnection.service(HttpConnection.java:816) at org.mortbay.http.HttpConnection.handleNext(HttpConnection.java:983) at org.mortbay.http.HttpConnection.handle(HttpConnection.java:833) at org.mortbay.http.SocketListener.handleConnection(SocketListener.java:244) at org.mortbay.util.ThreadedServer.handle(ThreadedServer.java:357) at org.mortbay.util.ThreadPool$PoolThread.run(ThreadPool.java:534) --- Thanks. marc
