将表单数据从jsp发送到Web服务客户端（SOAP）
[英]Sending form data from a jsp to a web service client (SOAP)
问题描述
Basically I have a web service connected to a database, that has an insert method. 
基本上，我有一个连接到数据库的Web服务，该服务具有insert方法。 I've created a registration form in a jsp and I need to send data the user inserted in the registration.jsp form to my web service. 我已经在jsp中创建了一个注册表单，并且需要将用户在registration.jsp表单中插入的数据发送到我的Web服务。 So I used a web service client invocation as the action to the registration.jsp when clicking the submit button. 因此，当单击“提交”按钮时，我将Web服务客户端调用用作对registration.jsp的操作。
I dont know how to get the data the user entered in the form and pass it to the web client who in turn insert it in my web service database. 我不知道如何获取用户在表单中输入的数据并将其传递给Web客户端，Web客户端又将其插入我的Web服务数据库中。
Here are my codes: 这是我的代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title> Registration</title>
</head>
<body>
<h1> Welcome</h1>
<form name="test" action="Wclient2.jsp" method="POST" enctype="multipart/formdata">
<table border="0">
<thead>
<tr>
<th>Register Here</th>
<th></th>
</tr>
</thead>
<tbody>
<tr>
<td>First Name:</td>
<td><input type="text" name="fname" value="" size="50" /></td>
</tr>
<tr>
<td>Last Name:</td>
<td><input type="text" name="lname" value="" size="50" /></td>
</tr>
<tr>
<td>Email:</td>
<td><input type="text" name="email" value="" size="50" /></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="password" value="" size="50"/> </td>
</tr>
<tr>
<td></td>
<td> <input type="submit" value="submit" name="submit" /> </td>
</tr>
</tbody>
</table>
</form>
</body>
</html>
And this is the code for the web client upon clicking the submit button of the 这是Web客户端上单击“提交”按钮的代码。
registration( action="Wclient2.jsp" method="POST")
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title> Enroll</title>
</head>
<body>
<h1> Welcome</h1>
<form name="test"<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<%-- start web service invocation --%><hr/>

try {
mypack.Bioweb_Service service = new mypack.Bioweb_Service();
mypack.Bioweb port = service.getBiowebPort();

java.lang.String password = "";

out.println("Result = " + result);
} catch (Exception ex) {
// TODO handle custom exceptions here

<%-- end web service invocation --%><hr/>
</body>
</html>
I dont know how to get the parameters for fname from the registration.jsp to put in the web client. 我不知道如何从registration.jsp获取fname的参数以放入Web客户端。 When I write: 当我写：
java.lang.String fname = request.getParameter("fname");
to get the value of textfield fname into my web service, in my database a row is created but NULL is inserted instead of the values my user entered in the form. 为了将文本字段fname的值输入到我的Web服务中，在数据库中创建了一行，但是插入了NULL，而不是用户在表单中输入的值。
Please help. 请帮忙。

I dont see any issue with your client side code(html/jsp) if you use request.getParameter("fname") as long you provide input to FirstName. 如果您使用request.getParameter（“ fname”），只要您向FirstName提供输入，我的客户端代码（html / jsp）就不会出现任何问题。 To isolate the issue, print the value of fname in your jsp 为了找出问题所在，请在您的jsp中打印fname的值
String fname =request.getParameter("fname") ;
System.out.println("Value of first name " +fname) // this will print your console
java.lang.String result = port.insert(fname, lname, email, password);
If this prints your input correctly, you would need to see service implementation to check it reads and process the input correctly. 如果这样可以正确打印您的输入，则需要查看服务实现以检查它的读取并正确处理输入。 If it is fname is null , then we can come back to the HTML/JSP to have second look. 如果fname为null，那么我们可以回到HTML / JSP进行第二次查看。
Update: To see the request in details, you could use below code 更新：要查看请求的详细信息，可以使用以下代码
Enumeration reqParams= request.getParameterNames();
while (reqParams.hasMoreElements()) {
String key= (String) reqParams.nextElement();
String val = request.getParameter(element);
System.out.println(" Key ==> "+key+" , Value ==> "+val);
}
Try this and lets see if you get values for any of the input your enterd in your html form. 试试这个，让我们看看您是否获得了在html表单中输入的任何输入的值。

This isn't really my area of expertise, but instead of calling action="Wclient2.jsp" you could call action="pass.php" then create a php file to grab the variables and redirect to Wclient2.jsp passing your variables in a query string. 这实际上不是我的专业领域，但是您可以调用action =“ pass.php”而不是调用action =“ Wclient2.jsp”，然后创建一个php文件来获取变量并重定向到Wclient2.jsp，并在其中传递变量查询字符串。
For example in the pass.php file: 例如在pass.php文件中：
$fname = $_POST['fname'];
$lname = $_POST['lname'];
header( 'Location: http://www.yoursite.com/path/Wclient2.jsp?fname=' .fname. '&lname=' .lname );
That might be a really weird (or newbie) way to accomplish it, but just of the top of my head I do know that it works. 那可能是一种很奇怪（或新手）的实现方式，但是我的头顶上我确实知道它有效。 Hopefully someone else will have a more appropriate answer, but in case no one replies quickly enough, I hope this helps a little bit :) 希望其他人会有一个更合适的答案，但是如果没有人足够迅速地答复，我希望这会有所帮助:)
