[appengine-java] Springframework - problem with session forms in GAE for Java 1.3.0

This happens:

Can you elaborate on this part a bit more? What are you seeing that makes
you think it's initializing the datastore? Are you restarting the entire
dev_appserver after modifying the jsp? How large is your datastore (e.g. how
many entities, how many properties per entity, average size of each
property).
If you can file an issue with a very simple webapp that reproduces the
problem, that would be the best way for us to track the problem down.
Alternatively, you could hook a profiler up to the dev_appserver yourself
(for example, visualvm, hprof, or jprofiler). With three minutes of
execution time, there should be a pretty obvious hotspot.
I tried to set --jvm_flag=-Xmx1G in my dev_appserver.cmd file but it
does not seem to help much (i don't use eclipse)
Another other advice?

Wow, that sounds bad. You're saying that this happens while running the

using Eclipse, set -Xmx1G in the JVM arguments for your launch config. If

[appengine-java] Servlet filter not being called?
Hello! I'm new to App Engine and am jumping straight in and learning via writing an app, as you do. I figured that a good thing to do was to create a servlet filter that checks the user's login status, forwarding to the login page if they haven't got a login, or allowing the request through if they are logged in. I've created a filter and added it to web.xml with a url-pattern of / *. However, when I load my app's html page, the doFilter method isn't called. My logging output shows the filter being inited OK, but the doFilter doesn't get called. Is there something else I need to do to get this working? Thanks!

[appengine-java] Incoming mail handler runs slow
I've written an incoming mail handler and it works, that is, it does what I want it to do, but it runs slow, very slow. However, I'm not sure why it's so slow because I'm using the QuotaService to time how long the doPost() method of my email handler servlet is running and it's returning 0.00 CPU seconds and 0.04 API seconds, yet the logs routinely report the requests taking over 1ms. I notice that if I fire two emails in rapid succession at my app then usually the first one reports as taking 1+ ms to run then the second one will run in under 150ms, which is confusing me even more. It's almost like the app is having to spin up on every email it receives, but 10+ seconds for the spin up seems way too long.

Can you elaborate on this part a bit more? What are you seeing that makes
you think it's initializing the datastore? Are you restarting the entire
dev_appserver after modifying the jsp? How large is your datastore (e.g. how
many entities, how many properties per entity, average size of each
property).
If you can file an issue with a very simple webapp that reproduces the
problem, that would be the best way for us to track the problem down.
Alternatively, you could hook a profiler up to the dev_appserver yourself
(for example, visualvm, hprof, or jprofiler). With three minutes of
execution time, there should be a pretty obvious hotspot.
I tried to set --jvm_flag=-Xmx1G in my dev_appserver.cmd file but it
does not seem to help much (i don't use eclipse)
Another other advice?

Wow, that sounds bad. You're saying that this happens while running the

that
JSP file huge? Try raising the heap size of your JVM. For example, if
you're
using Eclipse, set -Xmx1G in the JVM arguments for your launch config.
If
you're running the dev_appserver from the command line, use
--jvm_flag=-Xmx1G.On Fri, Nov 13, 2009 at 12:51 PM, Steph

Is there a way that the JSP compile time can be speed up? This

[appengine-java] Creating an app with Fusion tables an Visualization
Hi App Engine community I am wanting to get some advice on an app I am looking to create. Basically the app is going to show analytics (google visualizations) to an authenticated user. These are the components that I am looking to employ. -send structured data from an external source into a google fusion table. -based on the user that logs in, query the data and display visualizations to them. Would fusion tables, GWT, GAE, Visualizations be the best components to use and are there any good code examples out there? I have stepped through a few other examples Stockwatcher example, gdata example, message board example, so have a basic grasp of the technologies Any thoughts? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Simple one to many problem!!!
The difference between your code and the code in the blog post is that
you're calling em.persist() on the child object but the blog post is calling
em.persist() on the parent object. If you want to take advantage of
implicit entity group assignment it's important to manage children via their
parents. If you switch em.persist(search) to em.persist(member) you should
be fine.
