Colegas, tenho as duas classes abaixo e o erro que está ocorrendo, por favor alguém já passou por essa dificuldade?

[code]package br.com.www.tags;

import javax.servlet.jsp.JspTagException;
import javax.servlet.jsp.tagext.TagSupport;

public class TagGerenciadorConteudo extends TagSupport {

private String uuid;

public String getUuid() {
	return uuid;
}

public void setUuid(String uuid) {
	this.uuid = uuid;
}

public int doStartTag() throws JspTagException {
	try {
		pageContext.setAttribute("search", getUuid(), 1);
	} catch (Exception e) {
		return 5;
	}
	return 6;
}

public int doEndTag() throws JspTagException {
	try {
		return 6;
	} catch (Exception e) {
		return 5;
	}
}

}

package br.com.www.tags;

import javax.servlet.jsp.tagext.*;

public class TagGerenciadorConteudoTransfer extends TagExtraInfo {

public TagGerenciadorConteudoTransfer() {
}

public VariableInfo[] getVariableInfo(TagData data) {
	return (new VariableInfo[] { new VariableInfo("search",
			"java.lang.String", true, 0) });
}

}
[/code]
