unable to deploy the application on google app engine : appengine-web.xml does not contain a element

Question

When i click to deploy the application on google app engine in netbeans ,these are the error messages produced. Let me tell you that initially, probably i entered the wrong password and the application failed to deploy. But now when i click to deploy the application it doesn't ask me the email or the password.

Anyway how can i resolve these errors ?

Damn, have you even read lines 1-3 of your error msg? It even includes a link to the docs. — alex, May 28 '12 at 07:36

To build on what @alex said....

You have in your first error log

Bad configuration: appengine-web.xml does not contain a <threadsafe> element. See http://code.google.com/appengine/docs/java/config/appconfig.html#Using_Concurrent_Requests for more information.

The first line

Bad configuration: appengine-web.xml does not contain a <threadsafe> element.

tells you what is wrong. The second line

See http://code.google.com/appengine/docs/java/config/appconfig.html#Using_Concurrent_Requests for more information.

indicates what part of the GAE documentation to study to fix your problem.

I must admit, the error log entries are very clear and helpful. I wish more could follow the example made for you here. If you are still stuck, please would you specify exactly what you are stuck on?

You can no longer put true in web.xml, it will result in the following compilation error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'threadsafe'. One of '{"http:// java.sun.com/xml/ns/javaee":description, "http://java.sun.com/xml/ns/javaee":display-name, "http:// java.sun.com/xml/ns/javaee":icon, "http://java.sun.com/xml/ns/javaee":distributable, "http://java.sun.com/xml/ ns/javaee":context-param, "http://java.sun.com/xml/ns/javaee":filter, "http://java.sun.com/xml/ns/javaee":filter- mapping, "http://java.sun.com/xml/ns/javaee" – IgorGanapolsky Dec 12 '12 at 18:15

@IgorGanapolsky You mention "web.xml". We were talking here about "appengine-web.xml". – Ian Marshall Dec 13 '12 at 10:08

Simply add

<threadsafe>true</threadsafe>

to your war/WEB-INF/appengine-web.xml

Like this:

    <?xml version="1.0" encoding="UTF-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
<application></application>
<version>1</version>
<threadsafe>true</threadsafe>

I think you have added this threadsafe property to web.xml instead of appengin-web.xml. Make sure it is added to appenginweb.xml. Thanks.
