Basta utilizar o método split do próprio Java.
Lembrando que como o caractere "+" é especial, este deve ser precedido pelos caracteres de escape "\\"

Exemplo:

Resolvi...

Transformo o objeto num mapa e envio o mapa no servlet...
Na minha aplicação JME pego o mapa transformo num objeto e recupero as propriedades.

Dúvida de iniciante em JSON...

é o seguinte, tenho o seguinte código...

Como posso recuperar o objeto novamente ou melhor ainda como recuperar as propriedades desse objeto?

Era como o Leonardo falou, o eclipse não estava colocando as libs no diretório web-inf/lib

Oi Leonardo fiz o que você sugeriu e mesmo assim não rodou...
Criei um projeto desktop e coloquei o código e rodou sem problemas sem nem precisar fazer o que você disse.
Mas, estou precisando rodar dentro de um servlet

...

Pessoal estou tentando rodar um exemplo de um servlet gerando um documento JSON.
Segue o código abaixo.

Adiciono as libs necessárias...
Nenhum erro ocorre em tempo de compilação.
Quando eu rodo o código obtenho o seguinte erro...

java.lang.NoClassDefFoundError: net/sf/json/JSONArray

Alguém já passou por este problema?

Pessoal estou precisando trocar dados entre um servlet e uma aplicação J2ME.
Estou pensando em trocar dados através de xml, usando a api do JDOM, é viável eu ficar trocando um arquivo xml de um lado para outro?
Alguém já fez isto?

Pessoal, segue o erro que estou obtendo.

Alguém sabe como resolver?

ok resolvido.
Estava criando uma outra instância e não aproveitando a instância criada pelo spring.

Achei o erro, faltava o "3" depois do hibernate...

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref local="mySessionFactory"/>
</property>
</bean>

Só que acabei voltando para o mesmo problema de antes, não estou conseguindo criar instâncias através do spring...

Pessoal estou tentando colocar o spring para controlar minhas transações do hibernate, mas estou tento o seguinte problema...
Aparentemente é como se alguma lib faltasse no meu classpath, mas pelo que vi está tudo ok.

Alguém saberia dizer porque este erro está acontecendo? ou alguém já teve este problema?

Pessoal alguém tem um bom tutorial ou exemplo mesmo que seja simples da comunicação de uma aplicação j2me com um servlet?

Desde já agradeço.

ALguém tem algum exemplo de uma aplicação seam que faz persistencia de dados sem usar ejb?
