[RESOLVIDO] Hospedar WebService

PauloAugusto · Setembro 19, 2016, 8:50pm

Como faço para hospedar um WebService Rest Java?
É a primeira vez que estou desenvolvendo um e não sei como disponibilizá-lo. Tenho que desenvolver alguma interface ou algo do tipo, ou é apenas gerar um arquivo .WAR e fazer upload?
Estou utilizando o NetBeans.

Desde já agradeço

Boa noite Paulo,

Cara você normalmente precisa apenas gerar o war. Tenta montar uma instância free no Amazon AWS, e coloca um Tomcat/JBoss para colocar o teu war.

PauloAugusto · Setembro 20, 2016, 11:55am

Eu tenho uma conta no KingHost com Tomcat. Fiz o upload do war mas nao consigo acessar as funções. Para acessar as funções é da mesma forma que no localhost?

aresmaverick · Setembro 20, 2016, 12:25pm

Deveria ser. Eu nunca usei o KingHost, mas o ideal é ver o que está acontecendo pelos logs do Tomcat. Normalmente os erros mais gritantes aparecem no catalina.out.

Talvez a sua aplicação não esteja subindo por algum problema de Build Path, falta de um jar, etc.

PauloAugusto · Setembro 20, 2016, 12:52pm

Conferi tudo e parece está tudo normal. Criei até um index.html para teste e ele está sendo executado. Não estou conseguindo é acessar as funções

aresmaverick · Setembro 20, 2016, 1:40pm

Realmente é muito estranho Paulo,

Quando você roda o projeto de dentro da IDE e deploya num Container, ele funciona localmente? Qual implementação do jax-rs você está usando? Pode colar o web.xml aqui?

PauloAugusto · Setembro 20, 2016, 1:54pm

Utilizo a implementação jax-rs da JBoss e meu web.xml é o padrão do NetBeans:

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
	 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
	 version="3.1">
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
</web-app>

aresmaverick · Setembro 20, 2016, 2:17pm

E esse cara está funcionando localmente? Normalmente temos uma definição sobre o servlet que vai responder as requisições. Vou tentar ler sobre o jax-rs da JBoss para ver se pode ser algum problema de configuração.

PauloAugusto · Setembro 20, 2016, 2:21pm

Sim. Ao clicar em testar projeto Rest no NetBeans, ele abre uma página com todas funções que programei e todas executam sem nenhum erro.
Lhe agradeço muito pela vontade de ajudar

aresmaverick · Setembro 20, 2016, 2:27pm

Sem problema Paulo,

Eu estou estranhando por que já fiz alguns WS e não tive todos esses problemas. Talvez o teu Netbeans esteja fazendo alguma coisa por debaixo dos panos que não estamos vendo. Dá uma olhada nesse site: http://howtodoinjava.com/resteasy/resteasy-tomcat-hello-world-application/

Repara como o web.xml dele tem o mapeamento do servlet. Tenta alinhar a tua aplicação com a desse tutorial e vê se funciona. Estou supondo que você está usando o RESTEasy, que é a implementação do jax-rs da JBoss.

Fico na torcida pelo funcionamento do sistema.

PauloAugusto · Setembro 20, 2016, 2:31pm

Irei ler e pesquisar mais sobre o assunto. Estou tendo dificuldades pois até então, nunca tinha desenvolvido um web service. Suas dicas foram de grande ajuda. Muito obrigado

Ola @PauloAugusto,

chegou a inserir a nova aplicação la no gerenciador de aplicações no painel da kinghost? ele aplica para um contexto geralmente seu.dominio.com/suaApp

PauloAugusto · Setembro 20, 2016, 2:58pm

Sim. Inseri a aplicação com o mesmo nome do arquivo .war

aix · Setembro 20, 2016, 2:59pm

como o colega acima falou, e no log nenhum erro ?

PauloAugusto · Setembro 20, 2016, 4:49pm

Teve alguns erros de recursos, acredito eu que seja em função da configuração falha do web.xml

Na realidade ele ta dizendo que o teu war está corrompido.[quote=“PauloAugusto, post:15, topic:335632”]

Alguém sabe o que pode estar causando esse erro? Já tentei verificar essa classe PedidoItem, só que ela está normal, exatamente como as outras e além disso funciona localmente.

Consegui resolver o problema!

Mudei a implementação do WebService para Jersey, adicionando os jar’s baixados no site oficial, seguindo o artigo desse link: http://www.k19.com.br/artigos/criando-um-webservice-restful-em-java/

Configurei meu web.xml da seguinte maneira:

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
             version="3.1">
        <display-name>WebService Ports</display-name>
        <servlet> 
            <servlet-name>Jersey REST Service</servlet-name> 
            <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> 
            <init-param> 
                <param-name>com.sun.jersey.config.property.packages</param-name> 
                <param-value>br.com.suitesistemas</param-value> 
            </init-param> 
            <load-on-startup>1</load-on-startup> 
        </servlet> 
        <servlet-mapping> 
            <servlet-name>Jersey REST Service</servlet-name> 
            <url-pattern>/*</url-pattern> 
        </servlet-mapping>
    </web-app>

Por fim, esse último erro que postei, foi devido ao JDK de compilação. Ele estava na versão mais nova (JDK 8), mudei para JDK 7 nas propriedades do projeto, gerei o arquivo .war novamente, fiz o upload e deu certinho.
Muito obrigado a todos que me ajudaram!
