如何在Tomcat上进行午餐JSP项目？我将WebContent文件webapp夹复制到Apache的文件夹,但它找不到我的jsp页面,但如果我将jsp更改为jsf(index.jsf)工作正常.我怎么解决这个问题？

web.xml中:

    This parameter tells MyFaces if javascript code should be allowed in

在Windows 7 x64和PostgreSQL 9.0上安装pl/java时出错.

CREATE FUNCTION sqlj.java_call_handler()
  RETURNS language_handler AS 'pljava'
  LANGUAGE C;

错误:

错误:无法加载库"C:/ Program Files/PostgreSQL/9.0/lib/pljava.dll":找不到指定的模块.

*** 错误 ***

错误:无法加载库"C:/ Program Files/PostgreSQL/9.0/lib/pljava.dll":找不到指定的模块.SQL状态:58P01

但我确信pljava.dll存在于C:/ Program Files/PostgreSQL/9.0/lib中

问题是,当我将f:ajax的render属性设置为@form时,btnCreateCSV正确渲染.但是,如果我将其更改为按钮的ID,则不会发生任何事情.我想知道,我怎么能解决这个问题.这是我的xhtml代码:

<h:panelGrid layout="block">
            <h:commandButton value="View SQL" action="#{sparqlQueryBean.convert}" id="btnViewSql">
                <f:ajax execute="txtQuery btnCreateCSV" render="btnCreateCSV txtSqlQuery" onevent="waiting" listener="#{sparqlQueryBean.generateCommands}"></f:ajax>
            </h:commandButton>
            <h:commandButton value = "CSV" action = "#{sparqlQueryBean.createCSV}" id = "btnCreateCSV" rendered="#{sparqlQueryBean.showCSV == true}">
                <f:ajax execute="@none" render = "@none" onevent="waiting"></f:ajax>
            </h:commandButton>

这是我的豆类.在generateCommands方法中,showCSV的值设置为true.但它不起作用.

    public void generateCommands (AjaxBehaviorEvent event) {
    this.setShowCSV(true);
}
