Re: [appengine-java] Re: periodic downtimes
Well, I've submitted 2 or 3 tickets to their support team last week and haven't heard back yet. Perhaps I'm doing something wrong. As far as how our app did on the app-engine: it was pretty smooth. I think the main issue we ran into was the 10 writes per entity group per second. I think that restriction may force us onto a different platform. I think we could have worked around that restriction by employing more clever memcache usage, especially now that there is CAS enabled on the memcache, but I'd be slightly nervous about updates living in memcache and getting dropped before we wrote them to the datastore. My clients pretty much decided they want to try another hosting solution, so I guess that's my only option lol. Thanks for the reply!

My users wind up getting a 500 error on requests that just read data, usually even if the datastore has issues, you can still read from it. I'd be comfortable using memcache, but I'd want to ensure it had the same data integrity as the datastore (or something close anyhow). The nice thing about the datastore is that there is optimistic locking, so I know when there's contention. Currently, our users collectively modify data at about the same time (like 7-12 updates in a single second from several users), it's pretty important that I keep them in order, so I currently have my writes wrapped in a datastore transaction with a loop that runs about 5 times or until the transaction succeeds. Has anyone managed that type of contention in the memcache? If so, I'd love to hear some techniques that can ensure no update tramples a previous concurrent update. I've submitted inquiries to the billing and CPU request form, but haven't heard back. Does it usually take longer than 24 hours to hear back from the app-engine support team?

[appengine-java] Re: GAEJ app on a local GWT -noserver equivalent setup?
BTW, the MaintainJ webapp doesn't write anything on the server-side, so I doubt it will have trouble running on the GAEJ-configured Embedded Jetty server. Plus locally it runs on the NORMAL default SUN- ORacle JRE, and thus not on the specific/limited environment available in the GAEJ clouds! Could someone at least point out what the path of the GAEJ local Embedded Jetty server is? I want to try to deploy a second War in to be loaded for each server-instance. On Feb 14, 3:19 am, b4l4nc3r b4l4n...@gmx.com wrote: Yeah, I see, and agree with your point. And I did try it myself, although I mentioned it cryptically with Googled tested. And from the feedback from your perception, I mis-communicated it, because I didn't intend to take the indicated complex approach. Btw, MaintainJ is a tracing tool, to trace Java call-flows for a specific use-case, like logging-in/authentication for instance, to generate automated Sequence Diagrams, which then are easily usable in Eclipse to navigate to linked source-code and have instant flow- insight on a case-to-case basis. It also shows which Strings are being communicated during the call, and recently one can even see the complete SQL prepared statement generated by any persistence layer, like JPA implementations, etc.. To use the tool, however, one has to set it up on the same server (servlet container) on which the webapp --targeted to trace its Java calls-- will run/debug from. GAEJ comes with its own embedded Jetty one, of which I couldn't find the location to pull-off the setup. I need to deploy a second war file containing the MaintainJ tracing webapp, to run it on the same server-instance as the GAEJ app I'm building/debugging locally. The Eclipse GAEJ launch configuration tab doesn't offer any relevant options, nor could I find an argument switch. So I thought to use a fresh one I could setup myself. GWT offers the -noserver switch so that one could use another (non- embedded) server. I couldn't find the same option for GAEJ. I mentioned MaintainJ to point out my use-case for what I'm asking. My concrete questions are: 1. Is it possible to test/debug/run a GAEJ app locally on a different server than the embedded Jetty one? It can even be another Jetty configuration, but it has to be an external one rather then the embedded one. So that I deploy another webapp to be loaded in the same server-instance, and add specific libraries to the server lib dir/ path. 2. Otherwise can one do the same on the default GAEJ local embedded Jetty server? In both cases, if yes, how can one do that exactly? Or where should I look for more relevant information? Thanks so far.

What you're asking for is so specific so probably nobody has exactly tried what you're asking for. So, people are careful: if they don't know, they will not answer. 1 main point for that: gae made quite a few changes of the jre (See the while list of emulated classes) and added very specific stuff to its dev env (datastore, tasks, namespace, etc.). SO, it's hard to tell if it works elsewhere or not unless you try it. Something I can propose though: why don't you work the other round: you respect servlet api + you have DAOs (matching your databases9 for you data access. Then, you can do what you want with maintainj and then moving the app to gae should be pretty staightforward (you replace your DAOs with their gae datastore version). gae brings its own philosophy: most developers respect it (i.e develop with the sdk and local server) to then leverage the real live environment as soon as possible.

Hi, Oh yeah, I understand that blobstore is the way to go for storage aspects. No issue there. However, our customers have automated ftp scripts which posts these files out to ftp servers. It would have been helpful to atleast fetch files from ftp servers from within GAE, if not post to it. (although technically they are akin) Now, I will need to host another application outside GAE to do the dirty work and feed it to GAE using http. Architecturally, introduces more pieces and risk..

As a temporary stopgap, if you're using URLFetch service, you can use the doNotValidateCertificate() method in FetchOptions (http://code.google.com/appengine/docs/java/javadoc/com/ google/appengine/api/urlfetch/FetchOptions.html) to disable validation. -Fred On Feb 13, 5:02 am, harri mauria hmau...@googlemail.com wrote: I am having similar problems with the recently released version com.google.appengine.eclipse.sdkbundle.1.4.2_1.4.2.v201102111811 Problems happen with the development server, not in production.

When I call the URLFetchService.fetch API with a https URL I get a javax.net.ssl.SSLHandshakeException. for example when I fetch https://spreadsheets.google.com/feeds/ list/ I get javax.net.ssl.SSLHandshakeException: Could not verify SSL certificate for:https://spreadsheets.google.com/feeds/list/... When I switch back to an older SDK this doesn't happen. Is there a Help us test Prerelease SDK 1.4.2 thread I can post this to? Can anyone confirm this bug reproduces?

We did this because sometimes we want to develop with live data. However after upgrading to 1.4.2, https outbound call starts failing (see below). If we change to http, then it works again. It seems like some class is marked as restricted in this release. Is it intentional? What's the reason behind not allowing outbound https call? Thanks. java.lang.NoClassDefFoundError: javax.net.ssl.SSLHandshakeException is a restricted class.
