我目前正在将GWT应用程序从JBoss 5.1迁移到JBoss 7.0 EAP服务器.
我在部署到服务器的战争中捆绑了gwt-servlet.jar
我收到以下错误.

我没有最新的源代码,但在服务器上部署了war(最新)文件.

请建议最好的方法
1)从war/ear中检索源代码
2)比较和合并/更新可用的源代码与war/ear中的代码但可用源代码中缺少(我使用的是ECLIPSE IDE)

我正在将我的应用程序从Weblogic 9迁移到12c.

连接池 - 为我的应用程序创建的cvSybasepool在Web逻辑9上正常工作.
我使用com.sybase.jdbc.SybDriver连接到Weblogic 9上的Sybase数据库.

在Weblogic 12c上复制连接池(cvSybasepool)后,出现以下错误:

下面是我的代码(客户端),通过JQUERY Ajax调用以JSON格式发送表单数据

$(document).ready(function(){
    var contextroot = "/services/"
    $("#customerForm").submit(function(e){
        e.preventDefault();
        var form = $(this);
        var action = form.attr("action");
        var data = form.serializeArray();

        $.ajax({
                    url: contextroot+action,
                    dataType: 'json',
                    type: 'POST',
                    contentType: 'application/json',
                    data: JSON.stringify(data),
                    success: function(data){
                        console.log("DATA POSTED SUCCESSFULLY"+data);
                    },
                    error: function( jqXhr, textStatus, errorThrown ){
                        console.log( errorThrown );
                    }
        });
});
});

下面是接受JSON数据的SPRING控制器(服务)

@RequestMapping(value="/customer/create", method = RequestMethod.POST)
    public CustomerDTO create(@RequestBody CustomerDTO customerDTO) {
        return customerService.create(customerDTO);
    }

在提交表单时,我收到以下错误
HTTP400:BAD REQUEST - 由于语法无效,服务器无法处理请求.

我想这个错误是因为表单数据被序列化为JSON对象的数组,而不仅仅是请求体中的JSON对象,如下所示

[{ "Name": "名字", "值": "约翰"},{ "名": "姓氏", "值": "米勒"},{ …

我需要在 JBOSS EAP 7.0 服务器中创建一个 oracle 数据源

我使用以下命令从 JBOSS 管理 CLI（命令行界面）部署了ojdbc6.jar

deploy <PATH_TO_ORACLE_DRIVER_JAR>

部署驱动程序后，我可以看到服务器日志如下

01:25:53,338 INFO  [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-1) WFLYJCA0018: Started Driver service with driver-name = ojdbc6.jar

但是当我尝试从 Jboss 管理控制台创建 oracle 数据源（oracle.jdbc.driver.OracleDriver 作为驱动程序类）时，出现以下错误

我正在使用 Jsch(Jcraft) 库与 SSH 服务器建立 SSH 连接，如下所示：

        int port = 22;
        String privateKey = "***.ppk";//Path to private key(The file is in .ppk format)
        try 
        {
            jsch.addIdentity(privateKey);
            Session session = jsch.getSession(user, host, port);
            java.util.Properties config = new java.util.Properties(); 
            config.put("StrictHostKeyChecking", "no");
            session.setConfig(config);
            session.connect();
            ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
            sftpChannel.connect();
            /*file transfer code*/
            sftpChannel.disconnect();
            session.disconnect();
        }
        catch (Exception e) 
        {
            e.printStackTrace();
