我在liferay 中有.jsp，并在applet 中使用javascript，但是在将表单发送到portlet 之后，在服务器端，portlet 不会捕获表单，并且不会在日志中显示其他消息。
jsp页面的片段：
<script type="text/javascript">
function processSigning(){
var applet = document.applets["SignApplet"];
var path_to_certificate = document.getElementById("certificate").value;
var pass = document.getElementById("password").value;
var filePath = document.getElementById("documentSign").value;
applet.filePath = document.getElementById("documentSign").value;
applet.profileTestPKCS12(path_to_certificate, pass);
document.getElementById("file").value = applet.getDocumentString(filePath);
document.getElementById("sign").value = applet.getSignString();
document.getElementById("cert").value = applet.getCertificateString();
document.getElementById("mainForm").submit();
}
</script>
<form id="mainForm" action="<portlet:actionURL>
<portlet:param name="COMMAND" value="LOAD"/>
</portlet:actionURL>">
<hidden id="file" value="asdf"></hidden>
<hidden id="cert" value="asdf"></hidden>
<hidden id="sign" value="asdf"></hidden>
<input type="button" onClick="processSigning();" value="click here!" >
</form>
小门户片段：
public void processAction(ActionRequest request, ActionResponse response) throws PortletException {
session = request.getPortletSession(true);
String command = request.getParameter("COMMAND");
System.out.println("command=" + command);
log.info("command=" + command);
if ("LOAD".equals(command)) {
{
System.out.println("file");
log.info("file");
String fileBase64 = request.getParameter("file");
System.out.println(request.getParameter("file"));
log.info(request.getParameter("file"));
}
}
}
