Bug ID: 69570
Summary: The URL construction error of the tag <JSP:include>
Product: Tomcat 10
Version: 10.1.30
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org
Reporter: gon...@huiqing-sh.com
Target Milestone: ------
For JSP code like this:
<jsp:include page="/appmenu.do?method=tinit" flush="true">
<jsp:param name="linkto" value="Something"/>
</jsp:include>
In 10.1.30 and higher(includes 10.1.34), It will be compiled to:
String _jspx_temp1_url = "/appmenu.do?method=tinit";
String _jspx_temp1_requestEncoding = request.getCharacterEncoding();
org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response,
_jspx_temp1_url + "?" +
org.apache.jasper.runtime.JspRuntimeLibrary.URLEncode("linkto",
_jspx_temp1_requestEncoding)+ "=" +
org.apache.jasper.runtime.JspRuntimeLibrary.URLEncode("Something",
_jspx_temp1_requestEncoding), out, true);
In summary, when the parameter "page" of the tag <jsp:include> already contains
character "?", compiler still uses "?" to append the parameter of the tag
<jsp:param>.
For reference:
In 10.1.28, The compiled result of the JSP code mentioned above is:
org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response,
"/appmenu.do?method=tinit" + "&" +
org.apache.jasper.runtime.JspRuntimeLibrary.URLEncode("linkto",
request.getCharacterEncoding())+ "=" +
org.apache.jasper.runtime.JspRuntimeLibrary.URLEncode("Something",
request.getCharacterEncoding()), out, true);
