我在JSF上传文件.我正在使用Tomahawk <t:inputFileUpload>,但同样的问题适用于例如PrimeFaces <p:fileUpload>和JSF 2.2 <h:inputFile>.

我有以下支持bean代码:

private UploadedFile uploadedFile; // +getter+setter

public String save() throws IOException {
    String name = uploadedFile.getName();
    System.out.println("File name: " + name);

    String type = uploadedFile.getContentType();
    System.out.println("File type: " + type);

    long size = uploadedFile.getSize();
    System.out.println("File size: " + size);  

    InputStream stream = uploadedFile.getInputStream();
    byte[] buffer = new byte[(int) size];  
    stream.read(buffer, 0, (int) size);  
    stream.close();  
}

我能够获取文件名,类型和大小,但我无法将此文件保存在特定路径中.我无法找出保存上传文件的正确方法.我怎样才能做到这一点？

我正在使用JSF1.1,我想从第一个更新第二个selectOneMenu并拥有此代码_

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://www.azureworlds.org" prefix="azure"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="x"%>
<%@ taglib uri="http://www.asifqamar.com/jsf/asif" prefix="a"%>

...

<h:outputText value="State* " />
<x:selectOneMenu value="#{hotelBean.state}">
                    <f:selectItem itemLabel="Select One" itemValue="" />
                    <f:selectItem value="#{hotelBean.mapStates }" />
                    <x:ajax update="city" listener="#{hotelBean.handleCityChange}" />

</x:selectOneMenu>

                <h:outputText value="City* " />
                <x:selectOneMenu id="city" value="#{hotelBean.city}">

                    <f:selectItem itemLabel="Select One" itemValue="" />

                    <f:selectItem value="#{hotelBean.mapCities }" />
                </x:selectOneMenu>

第x行:ajax update ="city"listener ="#{hotelBean.handleCityChange}" 无法正常工作,我搜索但JSF1.1不支持Ajax.

那我该怎么办呢,我怎么能用javascript？我对JS的了解较少.感谢名单

我正在使用<p:dataTable>我使用的HTML <table>.我想<p:inputText>在<h:selectOneMenu>更改事件上禁用/ readonly PrimeFaces .

我使用的是JavaScript,但它没有使用它.

<script type="text/javascript">
 function change(val)
 {          
     //alert(val);
     if(val=="Check")
      {

         document.getElementById('bankName').readonly=false;
         document.getElementById('receiptNo').readonly=true;

      }
      if(val=="Cash")
      {

          forms.elements["mainForm:chkNo"].readonly=true;
          document.getElementById('chkNo').readonly=true;
          document.getElementById('bankName').readonly=true;
          document.getElementById('receiptNo').readonly=false;              

      }
}
</script>

JSF代码

<h:column>
                            <p:dataTable id="paymentHistoryDataTable" var="due" 
                                         >

                                <p:column>
                                    .......

                                    <table id="paymentProcess">
                                        <tr>                                                
                                            <td style="width: 80px;">
                                        <h:selectOneMenu value="#{adminActionController.tempBean.selectType}" id="type" onchange="change(this.value);">
                                            <f:selectItem itemLabel="Check" itemValue="Check"/>
                                            <f:selectItem itemLabel="Cash" itemValue="Cash"/>
                                        </h:selectOneMenu>
                                        </td>
                                        </tr>
                                        <tr id="check">
                                            <td></td>
