[appengine-java] Problem with AppStats
Hey Everyone, I just downloaded the new SDK and i was excited to use app stats. After following the instructions to set it up, I tried testing it on my localdev server and I got a nullpointerexception WARNING: /appstats/stats java.lang.NullPointerException at java.io.Reader.init(Reader.java:61) at java.io.InputStreamReader.init(InputStreamReader.java:80) at com.google.appengine.tools.appstats.TemplateTool.loadTemplateSource(TemplateTool.java: 115) at com.google.appengine.tools.appstats.Renderer $1.loadTemplateSource(Renderer.java:41) at com.google.appengine.tools.appstats.TemplateTool.getTemplate(TemplateTool.java: 142) at com.google.appengine.tools.appstats.TemplateTool.format(TemplateTool.java: 100) at com.google.appengine.tools.appstats.Renderer $1.format(Renderer.java:51) at com.google.appengine.tools.appstats.Renderer.renderSummaries(Renderer.java: 66) at com.google.appengine.tools.appstats.AppstatsServlet.doGet(AppstatsServlet.java: 99) at javax.servlet.http.HttpServlet.service(HttpServlet.java:693) at javax.servlet.http.HttpServlet.service(HttpServlet.java:806) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java: 511) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1166) at com.google.appengine.tools.appstats.AppstatsFilter.doFilter(AppstatsFilter.java: 92) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.appengine.api.blobstore.dev.ServeBlobFilter.doFilter(ServeBlobFilter.java: 51) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java: 43) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.appengine.tools.development.StaticFileFilter.doFilter(StaticFileFilter.java: 122) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java: 388) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java: 216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java: 182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java: 765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java: 418) at com.google.apphosting.utils.jetty.DevAppEngineWebAppContext.handle(DevAppEngineWebAppContext.java: 70) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java: 152) at com.google.appengine.tools.development.JettyContainerService $ApiProxyHandler.handle(JettyContainerService.java:349) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java: 152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java: 542) at org.mortbay.jetty.HttpConnection $RequestHandler.headerComplete(HttpConnection.java:923) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:547) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java: 409) at org.mortbay.thread.QueuedThreadPool $PoolThread.run(QueuedThreadPool.java:582) Anyone have any idea why? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Problem with AppStats
Hi,
I tried.
After successfully running the following was added to the web.xml.
servlet
servlet-nameappstats/servlet-name
servlet-classcom.google.appengine.tools.appstats.AppstatsServlet/servlet-class
/servlet
servlet-mapping
servlet-nameappstats/servlet-name
url-pattern/appstats/*/url-pattern
/servlet-mapping
security-constraint
web-resource-collection
url-pattern/appstats/*/url-pattern
/web-resource-collection
auth-constraint
role-nameadmin/role-name
/auth-constraint
/security-constraint
filter
filter-nameappstats/filter-name
filter-classcom.google.appengine.tools.appstats.AppstatsFilter/filter-class
init-param
param-namelogMessage/param-name
param-valueAppstats available:
/appstats/details?time={ID}/param-value
/init-param
/filter
filter-mapping
filter-nameappstats/filter-name
url-pattern/*/url-pattern
/filter-mapping
I think that I should confirm the environment such as jar files
when there is no difference compared with your web.xml .
please try.
thanks.
