JSPs using Custom Tag with Boolean attribute cannot compile

Question

Hi,
In Oracle9iAS(9.0.3), a jsp using a tag extension, which has a Boolean attribute, caused the following compile error, although the jsp is valid in other web containers.
ERROR:
/opt/oracle/j2ee/home/application-deployments/simple/simple/persistence/_pages/_test.java:56: Method toBoolean(java.lang.Boolean) not found in class _test.
__jsp_taghandler_1.setExists( OracleJspRuntime.toBooleanObject( toBoolean( b)));
JSP:
<%@ page language="java" %>
<%@ page errorPage="error.jsp" %>
<%@ taglib prefix="jnpr" uri="/WEB-INF/testtag.tld" %>
<%
Boolean b = Boolean.valueOf("true");
%>
<jnpr:TestTag exists="<%= b%>"/>
The boolean value is <%= b %>
Tag Handler:
package defaultpak;
import javax.servlet.jsp.tagext.*;
import javax.servlet.jsp.*;
public class TestTag extends TagSupport{
private Boolean exists = null;
private java.lang.Boolean getExists() {
return exists;
public void setExists(java.lang.Boolean newExists) {
exists = newExists;
public int doStartTag() throws JspException {
return super.doStartTag();
Is this a known problem? Is there a way to get around this?
Thanks in advance.
Fred

This is a known issue with 903, fixed in coming 904.
In 903 the workaround is to use primitive type "boolean" instead of Object type "java.lang.Boolean" in user's getter and setter code for the taglib.
