[appengine-java] Re: App instance recycling and response times - is there solution?
If you are experiencing failed requests on your long-running /
requests, consider performing some kind of "pre-warming" procedure of
your own... If you are getting timeout errors, Ping a do-nothing url,
and wait for it to return before running the big job. If it's a big
job, users should expect to wait anyway {and you should tell them they
are waiting!}, so the ping ensures {almost} that a warm JVM is running
in the server nearest said users, and then the big /request can
{usually} avoid getting killed with extra spin up time. Very unlucky
users would get a /ping on an old JVM, and /request a new one, but...
Technology isn't perfect... YET!

[appengine-java] Re: One-to-many querying for a child instance
The thread
http://groups.google.com/group/google-appengine-java/browse_thread/thread/2acea43161d8ac5/96c77de6c686526d?lnk=gst
is dealing with the same kind of problem. Basically it's not possible
to filter on the name property. So I guess I have two ways of doing
it.
1/ Creating the key by hand bu I have to know the parent key.
Key key = new KeyFactory.Builder("A", "A").addChild("B",
"B").getKey();
B bp = pm.getObjectById(B.class, key);
2/ Using an extent and filter the name property if I don't know the
parent key
B bp = null;
Extent e = pm.getExtent(B.class);
Iterator it = e.iterator();
while (it.hasNext()) {
B rsb = it.next();
if ("B".equals(rsb.getName())) {
bp = rsb;
break;
}
}
e.closeAll();

Re: [appengine-java] java.security.AccessControlException: access denied java.net.NetPermission specifyStreamHandler
In the htmlunit it's use java.net.URL,so you must check the port of the request url! It's a little limit in the GAE: The URL must use the standard ports for HTTP (80) and HTTPS (443). The port is implied by the scheme, but may also be mentioned in the URL as long as the port is standard for the scheme (https://...:443/). An app cannot connect to an arbitrary port of a remote host, nor can it use a non-standard port for a scheme. detail see:http://code.google.com/appengine/docs/java/urlfetch/overview.html 2010/1/30 Andreas Blomqvist > Ok! > > its a htmlunit package that gets the error > >[java] Jan 30, 2010 11:38:45 AM > com.google.apphosting.utils.jetty.JettyLogger warn > [java] WARNING: Error for /myservlet > [java] java.lang.ExceptionInInitializerError > [java] at > com.xxx.fs.FSServlet.processRequest(FSServlet.java:93) > [java] at com.xxx.fs.FSServlet.doGet(FSServlet.java:257) > [java] at > javax.servlet.http.HttpServlet.service(HttpServlet.java:693) > [java] at > javax.servlet.http.HttpServlet.service(HttpServlet.java:806) > [java] at > org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) > [java] at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1093) > [java] at > com.google.appengine.api.blobstore.dev.ServeBlobFilter.doFilter(ServeBlobFilter.java:51) > [java] at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) > [java] at > com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java:43) > [java] at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) > [java] at > com.google.appengine.tools.development.StaticFileFilter.doFilter(StaticFileFilter.java:121) > [java] at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) > [java] at > org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:360) > [java] at > org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) > [java] at > org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) > [java] at > org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:712) > [java] at > org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) > [java] at > com.google.apphosting.utils.jetty.DevAppEngineWebAppContext.handle(DevAppEngineWebAppContext.java:70) > [java] at > org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:139) > [java] at > com.google.appengine.tools.development.JettyContainerService$ApiProxyHandler.handle(JettyContainerService.java:352) > [java] at > org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:139) > [java] at org.mortbay.jetty.Server.handle(Server.java:313) > [java] at > org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:506) > [java] at > org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:830) > [java] at > org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:514) > [java] at > org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:211) > [java] at > org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:381) > [java] at > org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:396) > [java] at > org.mortbay.thread.BoundedThreadPool$PoolThread.run(BoundedThreadPool.java:442) > [java] Caused by: java.security.AccessControlException: access denied > (java.net.NetPermission specifyStreamHandler) > [java] at > java.security.AccessControlContext.checkPermission(AccessControlContext.java:323) > [java] at > java.security.AccessController.checkPermission(AccessController.java:546) > [java] at > java.lang.SecurityManager.checkPermission(SecurityManager.java:532) > [java] at > com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkPermission(DevAppServerFactory.java:151) > [java] at java.net.URL.checkSpecifyHandler(URL.java:629) > [java] at java.net.URL.(URL.java:501) > [java] at > com.gargoylesoftware.htmlunit.util.UrlUtils.toUrlUnsafe(UrlUtils.java:91) > [java] at > com.gargoylesoftware.htmlunit.util.UrlUtils.toUrlSafe(UrlUtils.java:62) > [java] at > com.gargoylesoftware.htmlunit.WebClient.(WebClient.java:161) > [java] ... 29 more > [java] Jan 30, 2010 11:38:45 AM > com.google.apphosting.utils.jetty.JettyLogger warn > [java] WARNING: Nested in java.lang.ExceptionInInitializerError: > [java] java.securi
