Como executar o google app engine no Netbeans

Assuntos Gerais
#1

É o seguinte baixei a sdk do google app engine e instalei o projeto de exemplo guestbook no netbeans…
porem qdo eu subo o tom cat me da o seguinte erro:

java.lang.NullPointerException
	com.google.appengine.api.users.UserServiceImpl.getCurrentUser(UserServiceImpl.java:79)
	org.apache.jsp.guestbook_jsp._jspService(guestbook_jsp.java:78)
	org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
	org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:374)
	org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:342)
	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
	org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)

Isto pq na jsp guestbook.jsp
tem o seguinte codigo:


UserService userService = UserServiceFactory.getUserService();
    User user = userService.getCurrentUser();

porem userService esta vindo nulo… e para rodar o exemplo necessita-se dele…
e esta UserServiceFactory esta no pacote do google engine… o qual esta fechado e não tenho como ver seu fonte…
minha duvida é pq esta factory do google engine esta me retornando null? como faço para ele funcionar?

#2

mais alguem?

#3

Cara, não sei se é bem isso , mas me parece que para usar os serviços do App Engine na maquina local é preciso que esteja rodando um ambiente local do App Engine. No Eclipse isso é realizado automaticamente pelo plugin, no Netbeans eu acho que é preciso passar alguns parâmetros para rodar.

#4

No Eclipse ele possui um plugin que já levanta o ambiente de execução do GAE.
No Netbeans você vai precisar meio que inserir manualmente este suporte, e executar no ambiente do GAE e não no Tomcat:

Instalei o plugin no Netbeans e fiz exatamente o mesmo exemplo do video porem da o seguinte erro qdo sobe o server:

HTTP ERROR: 500

O que pode ser?

Acredito que o problema esteja na versão do java…
pois quando eu vou adicionar a app só aparece a opção para Java 5 e o que tenho instalado é o 6… o App Engine não tem suporte para o 6?

#8

por alguma zica não achou o javac.
Quanto a versão não tem problema nenhum. Já utilizei o GAE com Java5 e Java6.

Por que você num usa o Eclipse?Nunca testei com o Netbeans, mas me parece tãoooo mais simples.

copia O COPILADOR javac desse diretorio - D:\Arquivos de programas\Java\jdk1.6.0_18\bin
no caso esse diretorio e da minha maquina vc vai copia da sua
e cola D:\Arquivos de programas\Java\jre6\bin

copia tambem desse diretorio - D:\Arquivos de programas\Java\jdk1.6.0_18\lib
o arquivos- TOOLS QUE É UM JAR

E COLA NESSE DIRETORIO - D:\Arquivos de programas\Java\jre6\lib
