问题描述
我正在定义一个自定义标签"htmlencoder".我有这些文件:
I am defining a custom tag "htmlencoder". I have These files:
WEB-INF/classes/HtmlEncoderTag.jar，具有如下所示的Java代码:
WEB-INF/classes/HtmlEncoderTag.jar ,with a java code like this:
import java.io.IOException;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyContent;
import javax.servlet.jsp.tagext.BodyTagSupport;
public class HtmlEncoderTag extends BodyTagSupport{
//....
}
WEB-INF/htmlencoder.tld:
WEB-INF/htmlencoder.tld :
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name></short-name>
<tag>
<name>htmlencode</name>
<tag-class>HtmlEncoderTag</tag-class>
<body-content>JSP</body-content>
</tag>
</taglib>
index.jsp:
index.jsp:
<%@ taglib uri="WEB-INF/htmlencoder.tld" prefix="htmlencoder"%>
<head>
<title>Watch out you sinners...</title>
</head>
<html>
<body bgcolor="white">
<htmlencoder:htmlencode><script <% //the error refers to this line %>
type="javascript">BadStuff()</script></htmlencoder:htmlencode>
</body>
</html>
运行页面时出现错误"HtmlEncoderTag无法解析为类型"，并且显示行index.jsp:7(如上所述).
I got the error "HtmlEncoderTag cannot be resolved to a type" when i run my page and it shows me the line index.jsp:7 ( I mentioned above).
我该怎么办?
推荐答案
我找到了答案.我不确定是否有必要，但是我的问题是通过以下方式解决的: 您必须将标签类放入包装中.例如，您的HtmlEncoderTag.jar文件应放置在WEB-INF/MyTag/中，并且应如下所示:
I found the answer. I'm not sure it is necessary, but my problem solved this way: You have to put your tag class in a package. for example, your HtmlEncoderTag.jar file should be placed in WEB-INF/MyTag/ and should be like this:
pckage MyTag;
import java.io.IOException;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyContent;
import javax.servlet.jsp.tagext.BodyTagSupport;
public class HtmlEncoderTag extends BodyTagSupport{
//....
}
您的tld文件将如下所示:
And your tld file will be like this:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name></short-name>
<tag>
<name>htmlencode</name>
<tag-class>MyTag.HtmlEncoderTag</tag-class>
<body-content>JSP</body-content>
</tag>
</taglib>
