[appengine-java] Re: JAXB Support
I was facing similar issue and use of 2.1.12 version of JAXB reference implementaion fixed the issue..Thanks On Apr 6, 10:41 pm, Toby Reyelts to...@google.com wrote: It looks like you're bundling the latest 2.2 JAXB RI. Apparently they made a change in that release which requires access to the protected method, ClassLoader.findLoadedClass. This makes it incompatible with App Engine. If you can use the previous release (2.1.2), a built-in version of JAXB, or even possibly a different implementation of 2.2, then you shouldn't see this problem anymore.

The local environment is just a simulation of the production environment. We put a lot of effort into emulating it, but there are some edge-cases that are much more difficult to handle than others.

[appengine-java] JSP problem with forced naming when trying to pass init-param to JSP
In volume 2 of CoreServlets and JavaServer Pages, Marty Hall
recommends using a url-pattern for the JSP to match its original URL.
However, I cannot do this in Appengine and provide init-param for the
JSP page.
If I have a InitPage.jsp shown below in the war folder, (war/
InitPage.jsp) and if I have a url-pattern of /InitPage.jsp shown in
below web.xml then I will get a 500 Server Error each time with a
error log description of java.lang.IllegalStateException: No forced
path servlet for /InitPage.jsp
Is there any way that I can have a jsp in the war folder with the same
name for a URL-Pattern and pass intialization parameters to the page.
Thanks
Dave

[appengine-java] Hibernate support for Google App Engine (Cloud2db)
Hi Everyone, Cloud2db http://www.cloud2db.com/ is pleased to announce the availability of Hibernate framework on Google App Engine. Now you can use Hibernate to access Cloud2db instances running on Google App Engine (Bigtable Datastore). You can also use Hibernate tools like database reverse engineering plugin directly against Cloud2db instances running on Google App Engine. You will need to install Cloud2db and register your appspot prior to deploying the Hibernate framework. Here are links to Download http://cloud2db.appspot.com/website/download.htmland Registrationhttp://cloud2db.appspot.com/website/registration.html . Here are the links to Hibernate distribution and a code sample. http://cloud2db.appspot.com/website/distributions/hibernate_dist.zip http://cloud2db.appspot.com/website/distributions/hibernate_sample.zip Please deploy Hibernate JAR files and sample code in your GAE environment. Please run the TestServer.java Servlet from the sample code to test the Hibernate functionality. Please make sure that this Servlet is accessed as an Admin resource by using the following entry in your web.xml file (use your servlet URL in url-pattern tag). security-constraint web-resource-collection url-pattern/url-pattern /web-resource-collection auth-constraint role-nameadmin/role-name /auth-constraint /security-constraint Thanks, Sandeep Sathaye Founder and Chief Architect Cloud2db -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
