[google-appengine] Protocol Buffers
is there any support in appengine for using protocol buffers for data transfer (eg. through RPCs). If not, what recommended practices do people have for minimizing latency between AppEngine and clients, when clients are spread across the globe? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

NoClassDef ReadPolicy$Consistency? (was Re: [appengine-java] using an Objectify query filter with IN -- IllegalArgumentException)
I just upgraded - thanks for the amazingly quick turnaround on my bug btw!! Unfortunately, I'm now getting java.lang.NoClassDefFoundError: com/google/appengine/api/datastore/ReadPolicy$Consistency at com.googlecode.objectify.ObjectifyOpts.init(ObjectifyOpts.java:25) at com.googlecode.objectify.ObjectifyFactory.begin(ObjectifyFactory.java:105) at com.googlecode.objectify.ObjectifyService.begin(ObjectifyService.java:29) I thought it might be because I was using a slightly older version of the AppEngine, so I updated that to 1.3.3, but still get the same result. Now my assumption is that there's something wrong with my configuration (I'm missing a jar I need?) but don't know which one. Can anyone tell me what jar com/google/appengine/api/datastore/ReadPolicy$Consistency is in? On Wed, Apr 21, 2010 at 11:10 PM, Jeff Schnitzer j...@infohazard.orgwrote: Fixed.

Re: NoClassDef ReadPolicy$Consistency? (was Re: [appengine-java] using an Objectify query filter with IN -- IllegalArgumentException)
Ok, So I can reliably recreate the issue. My app works fine with Objectify 2.02 and 2.1 but fails on the first DB read with 2.2. Any help would be appreciated.

[appengine-java] Re: noob question: HTML rendering as escaped in HTML widget
doh. I was setting the HTML content with setText() instead of setHTML(). so, uh, nevermind. thanks On Thu, Apr 22, 2010 at 5:54 PM, Larry White ljw1...@gmail.com wrote: I have a text string created in the RichTextArea widget. When viewed in that widget it shows as HTML with all the expected formatting (bold,etc.) When viewed in my com.google.gwt.user.client.ui.HTML widget it renders as if escaped, with all the markup visible. I've checked in Firebug and it doesn't appear that there's anything interesting going on with stylesheets - just setting widths, alignment and size. I never added a gwt-HTML class to my stylesheets so the actual div representing the HTML widget shows as having no style set. Any thoughts, etc. much appreciated. thank you! -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
