[appengine-java] Diagnosing problems with backends that are freezing

2012-01-19 Thread steveb
Are are using backends to parallelize large batches of work for our users. This involves adding 100's of tasks to a dedicated queue which spreads the tasks across 5 dynamic backends. Many of these tasks do a url fetch to external web services. When we run this for one user it seems to work fine bu

We used Janrain which has the added advantage of supporting N networks instead of just one. One caveat is that it makes the login slower because you go through Janrain redirects during login so test this to ensure it's fast enough for you if you try it. Steve On May 15, 12:35 am, Ravi Sharma wr

I've got an application that just started producing the following error from servlets. javax.servlet.ServletException: Content-Length must be specified at com.google.gwt.user.server.rpc.RPCServletUtils.readContentAsUtf8(RPCServletUtils.java: 168) at com.google.gwt.user.server.rpc.A

I have the answer. With help from the folks at Google I was told that the underlying problem was a ClassNotFoundException for isSerializable from the GWT toolkit. This explains why my other app worked ok, because it contained the GWT jar. This also means that the true problem was being masked by

The plot thickens. I just uploaded another version of my app with similar code, including the offending MappingUtils class. This version has no troubles with it. This means that the MappingUtils class is not really the problem - there is something specific to the version that is manifesting a Secur

OK, so I'm still digging and don't have answer yet but I thought I'd give an update in case it sparks an idea and it'll be useful as a future reference. Firstly getting to the real error is a challenge because Guice on Appengine does a lot of recursion when creating dependency trees. In this case

Hi, I've started to see a new exception for my application and I'm hoping that a kind Googler can look this up for me. My appid is catapult-lb and here's the stack trace. I'd be grateful for any help as this has been working for more than 6 months and now (probably due to a code change of mine) I'

I'm also very interested in this feature. I'm looking at plugging in Lucene ( http://www.kimchy.org/searchable-google-appengine-with-compass ) to achieve search but I can imagine that there will be lots of issues with storage, indexing, security, CPU use etc with this solution. If we can get an in
