However it it a good investment for the resume?

Hi all, do/did you use Websphere plataform in any project?

I've correctly setup Glassfish v3 in Eclipse and I've created a server in the Servers console. I created a project and then copied 3 files of the chapter 1 example from the book website www.manning.com/panda

HelloUser.java
package ejb3inaction.example; import javax.ejb.Remote; @Remote public interface HelloUser { public void sayHello(String name); }

HelloUserBean.java
package ejb3inaction.example; import javax.ejb.Stateless; @Stateless public class HelloUserBean implements HelloUser { public void sayHello(String name) { System.out.println("Hello " + name + " welcome to EJB 3 In Action!"); } }

HelloUserClient.java
package ejb3inaction.example; import javax.ejb.EJB; public class HelloUserClient { @EJB private static HelloUser helloUser; public static void main(String[] args) { helloUser.sayHello("Curious George"); System.out.println("Invoked EJB successfully ... see server console for output"); } }

I deploy the ejb in Glassfish successfully, but when I running HelloUserClient, I got NullPointerException
Exception in thread "main" java.lang.NullPointerException at ejb3inaction.example.HelloUserClient.main(HelloUserClient.java:9)

I know it's because helloUser reference to null. However, is it supposed to be right for this example? or Did I miss anything else? or I can't just copy and paste the sample code into eclipse and run from there? (the book examples are run in command line). I have no clue. Please help. Thanks

To skip out that code error try on:

package modelo; import javax.ejb.EJB; import appinterface.HelloUser; public class HelloUserClient { @EJB private static HelloUser helloUser = new HelloUserBean(); public static void main(String[] args) { helloUser.sayHello("Curious George"); } }

Does anybody have any exemple that use web interface?

Prithvi Sehgal, worked!

thanks a lot...

now I am facing trouble applying CSS look at:

<h:column headerClass="cabecalho"> <f:facet name="header"> <h:outputText value="Código Produto"></h:outputText> </f:facet> <font size="2" color="black" face="verdana">#{resultadoPesquisa.codigo_produto}</font> </h:column>


cabecalho is a CSS but does not apply for the grid's hearder...

Hi everyone, how are you?

I would like to color my dataGrid's rows, I set this way:

<br /> <h:panelGrid columns="4" rendered="#{not empty epubVersionamentoBean.voEpubVersionamentoList}"> <h:dataTable id="lista" value="#{epubVersionamentoBean.voEpubVersionamentoList}" var="resultadoPesquisa" rowClasses="tableOddRow, tableEvenRow"> <h:column> <a href="xhtml/upload_epub.xhtml?#{resultadoPesquisa.ISBN_Livro_Impresso}"><img src="imagem/setinha.jpg"></img></a> </h:column> <h:column> <f:facet name="header"> <h:outputText value="Título"></h:outputText> </f:facet> #{resultadoPesquisa.titulo} </h:column> <h:column> <f:facet name="header"> <h:outputText value="Autor"></h:outputText> </f:facet> #{resultadoPesquisa.autor} </h:column> <h:column> <f:facet name="header"> <h:outputText value="Código Produto"></h:outputText> </f:facet> #{resultadoPesquisa.codigo_produto} </h:column> <h:column> <f:facet name="header"> <h:outputText value="ISBN"></h:outputText> </f:facet> #{resultadoPesquisa.ISBN_Livro_Impresso} </h:column> </h:dataTable> </h:panelGrid>


Where can I put the color?

sorry that works but not 100% right... let me explain better:

exemple:
if you try to compress a folder named exemple folder1 that has a child named file1 together another file named file2 that compresses but when you descompress the result is -> file1 and file2 instead of folder1/file1 and file2.

Could you help me with this method it crashed when reading a folder:

//método para compactar arquivo e ou diretorio public static void compactarParaZip(String arqSaida,String[] arqEntrada) throws IOException{ int cont; byte[] dados = new byte[TAMANHO_BUFFER]; BufferedInputStream origem = null; FileInputStream streamDeEntrada = null; FileOutputStream destino = null; ZipOutputStream saida = null; ZipEntry entry = null; try { destino = new FileOutputStream(new File(arqSaida)); saida = new ZipOutputStream(new BufferedOutputStream(destino)); for (int i = 0; i < arqEntrada.length; i++) { File file = new File(arqEntrada[i]); if(file.isDirectory()){ for (File arquivos : file.listFiles()) { streamDeEntrada = new FileInputStream(arquivos); //crashed here!!! origem = new BufferedInputStream(streamDeEntrada, TAMANHO_BUFFER); entry = new ZipEntry(arquivos.getName()); saida.putNextEntry(entry); while((cont = origem.read(dados, 0, TAMANHO_BUFFER)) != -1) { saida.write(dados, 0, cont); } } }else{ streamDeEntrada = new FileInputStream(file); origem = new BufferedInputStream(streamDeEntrada, TAMANHO_BUFFER); entry = new ZipEntry(file.getName()); saida.putNextEntry(entry); while((cont = origem.read(dados, 0, TAMANHO_BUFFER)) != -1) { saida.write(dados, 0, cont); } } } origem.close(); saida.close(); } catch(IOException e) { throw new IOException(e.getMessage()); } }

I got it...

So, I would like to get a complete method that works that, a method that compressess folders/directories beucase I was just trying... only an attempt...

Could you help me please?

I am trying but facing difficult, look at:

Throws IOException:
else { // Add ZIP entry to output stream. to.putNextEntry(new ZipEntry(to.toString())); // Transfer bytes from the file to the ZIP file int len; FileInputStream in = new FileInputStream(from); while ((len = in.read()) > 0) { to.write(len); } // Complete the entry to.closeEntry(); in.close(); }

I think the method is not complete...
