我的标签类如下:package org.tag.image;import java.io.IOException;import javax.servlet.jsp.JspContext;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.JspWriter;
import javax.servlet.jsp.tagext.JspFragment;
import javax.servlet.jsp.tagext.SimpleTagSupport;public class ImageTag extends SimpleTagSupport {
private JspFragment body;
private Image image;
public void setImage(Image image) {
this.image = image;
} public void doTag() throws JspException, IOException {
JspContext jspCtx = getJspContext();
JspWriter out = jspCtx.getOut();
out.println("<img src="+image.getPath()+"/>");
body.invoke(null);
} protected void getJspBody(JspFragment jspBody) {
this.body = jspBody;
}
}tld如下: <tag>
<name>logo</name>
<tag-class>org.tag.image.ImageTag</tag-class>
<body-content>tagdependent</body-content>
<attribute>
<name>image</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
JSP页面: <body>
<jsp:useBean id="image" scope="page" class="org.tag.image.Image"></jsp:useBean> <%image.setName("123");
image.setPath("./style/image/bg0.jsp");%>
<div id = "container">
<div id = "header">
<div id = "logo">
<my:logo image="image"></my:logo>
</div>
</div>
</div>
</body>运行后抛出异常:ServletException raised in SimpleFilter Unable to convert string "image" to class "org.tag.image.Image" for attribute "image": Property Editor not registered with the PropertyEditorManager
请问这个问题怎么解决,我就是想把一个image对象传入标签,让它在界面上显示。
