JavaWeb java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

问题

我在尝试使用Glassfish 5.0运行JavaWeb项目时遇到了错误。每次它试图从我的SQL数据库中获取数据时，都会出现以下错误。 <br>
StandardWrapperValve[ListadoPersonas]: Servlet.service() for servlet ListadoPersonas threw exception
java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

以下是调用从数据库获取数据的函数的servlet ListadoEstadosCiviles：

  1. GestorPersonas g = new GestorPersonas();
  2. ArrayList&lt;EstadoCivil&gt; lista = g.obtenerEstadosCiviles();
  3. for (EstadoCivil estadoCivil : lista) {
  4.     out.println("&lt;tr&gt;&lt;td&gt;" + estadoCivil.getId() + "&lt;/td&gt;&lt;td&gt;" + estadoCivil.getNombre() + "&lt;/td&gt;&lt;/tr&gt;");
  5. }

以下是GestorPersonas() 构造函数：

  1. public GestorPersonas() {
  2.     try {
  3.         Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
  4.     } catch (ClassNotFoundException ex) {
  5.         Logger.getLogger(GestorPersonas.class.getName()).log(Level.SEVERE, null, ex);
  6.     }
  7. }

以下是obtenerEstadosCiviles() 方法：

  1. public ArrayList&lt;EstadoCivil&gt; obtenerEstadosCiviles() {
  2.     ArrayList&lt;EstadoCivil&gt; lista = new ArrayList&lt;&gt;();
  3.     
  4.     try {
  5.         Connection conn = DriverManager.getConnection(CONN,USER,PASS);
  6.         Statement st = conn.createStatement();
  7.         ResultSet rs = st.executeQuery("select * from EstadosCiviles");
  8.         // 如果select语句只返回一行记录，使用if而不是while
  9.         while (rs.next()) {
  10.             int id = rs.getInt("id");
  11.             String nombre = rs.getString("nombre");
  12.             EstadoCivil ec = new EstadoCivil(id, nombre);
  13.             lista.add(ec);
  14.         }
  15.         
  16.         rs.close();
  17.         st.close();
  18.         conn.close();
  19.     } catch (SQLException ex) {
  20.         Logger.getLogger(GestorPersonas.class.getName()).log(Level.SEVERE, null, ex);
  21.     }
  22.     
  23.     return lista;
  24. }

我没有问题将我的Java应用程序连接到SQL，我认为问题出在Glassfish上，但我无法弄清楚为什么它不起作用。

这是调用obtenerEstadosCiviles()函数的servlet，我期望表中充满数据。

期望效果：
JavaWeb java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

更新

我刚刚检查了我的插件，发现Java Web和EE已经激活，但"Active"标志似乎没有激活。这可能是问题的一部分吗？
JavaWeb java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

英文:

I'm getting an error when trying to use a JavaWeb project using Glassfish 5.0. Everytime it tries to bring data from my SQL Database it gives me this error. <br>
StandardWrapperValve[ListadoPersonas]: Servlet.service() for servlet ListadoPersonas threw exception
java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

Here is the servlet ListadoEstadosCiviles where I call the function which brings the data back from my database

  1. GestorPersonas g = new GestorPersonas();
  2. ArrayList&lt;EstadoCivil&gt; lista = g.obtenerEstadosCiviles();
  3. for (EstadoCivil estadoCivil : lista) {
  4.     out.println(&quot;&lt;tr&gt;&lt;td&gt;&quot; + estadoCivil.getId() + &quot;&lt;/td&gt;&lt;td&gt;&quot; + estadoCivil.getNombre() + &quot;&lt;/td&gt;&lt;/tr&gt;&quot;);
  5. }

Here is GestorPersonas() constructor:

  1.  public GestorPersonas() {
  2.         try {
  3.             Class.forName(&quot;com.microsoft.sqlserver.jdbc.SQLServerDriver&quot;);
  4.         } catch (ClassNotFoundException ex) {
  5.             Logger.getLogger(GestorPersonas.class.getName()).log(Level.SEVERE, null, ex);
  6.         }
  7.     }

Here is obtenerEstadosCiviles() method

  1. public ArrayList&lt;EstadoCivil&gt; obtenerEstadosCiviles() {
  2.     ArrayList&lt;EstadoCivil&gt; lista = new ArrayList&lt;&gt;();
  3.     
  4.     try {
  5.         Connection conn = DriverManager.getConnection(CONN,USER,PASS);
  6.         Statement st = conn.createStatement();
  7.         ResultSet rs = st.executeQuery(&quot;select * from EstadosCiviles&quot;);
  8.         // Si el select devuelve una &#250;nica fila, en lugar de while, se usa un if
  9.         while (rs.next()) {
  10.             int id = rs.getInt(&quot;id&quot;);
  11.             String nombre = rs.getString(&quot;nombre&quot;);
  12.             EstadoCivil ec = new EstadoCivil(id, nombre);
  13.             lista.add(ec);
  14.         }
  15.         
  16.         rs.close();
  17.         st.close();
  18.         conn.close();
  19.     } catch (SQLException ex) {
  20.         Logger.getLogger(GestorPersonas.class.getName()).log(Level.SEVERE, null, ex);
  21.     }
  22.     
  23.     return lista;
  24. }

I have no problem connecting my java application to sql, I think the problem is with glassfish but i cant figure out why it is not working

This is the servlet that is calling obtenerEstadosCiviles() function, I expect that table full with data

What I expect:
JavaWeb java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

UPDATE

I've just checked my plugins and it appears that Java Web and EE it´s activated but the "Active" symbol doesnt appears active. Could this be part of the problem?
JavaWeb java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

答案1

得分: 6

基本上是相同的问题，最终通过这个解决方案解决了。

在你的glassfish文件夹中，进入glassfish5/glassfish/modules/endorsed/目录，用WinRAR或你偏好的解压工具打开grizzly-npn-bootstrap.jar文件。

删除sun文件夹，然后尝试重新运行你的程序。

英文:

Had basically the same problem, eventually solved it with this solution here.

In your glassfish folder go to glassfish5/glassfish/modules/endorsed/ and open the grizzly-npn-bootstrap.jar file with winrar or your preferred unzipper.

Delete the sun folder and try running your program again.
