One important question: What container are you targeting this for? If this is a JSP 2.0 container, there's an easier way to do this. Assuming you use the Servlet 2.4 schema in your web.xml, your JSP line would look like this:
<JavaComponents:calendar prevMonth="${param.prevMonth}" /> In this case, there's no need to declare variables or write any scriptlets. > -----Original Message----- > From: A mailing list about Java Server Pages specification > and reference [mailto:[EMAIL PROTECTED] On Behalf Of > Graeme McLaren > Sent: Wednesday, March 07, 2007 2:45 PM > To: JSP-INTEREST@JAVA.SUN.COM > Subject: custom tag - param passing prob > > Hi all, I am building my first custom tag and I want to pass > a value to variable around from a jsp to the custom tag: > > <JavaComponents:calendar prevMonth="<%= prevMonth %>" /> > > When I try to to run the JSP I get an error: > > org.apache.jasper.JasperException: Unable to compile class for JSP > > An error occurred at line: 23 in the jsp file: /calendarTag.jsp > > Generated servlet error: > [javac] Compiling 1 source file > > C:\Tomcat\work\Catalina\localhost\_\org\apache\jsp\calendarTag _jsp.java:90: > cannot resolve symbol > symbol : variable prevMonth > location: class org.apache.jsp.calendarTag_jsp > _jspx_th_JavaComponents_calendar_1.setPrevMonth( prevMonth ); > ^ > 1 error > > > Can anyone suggest anything to help get this working? > > > Cheers in advance, > > Graeme :) > > ============================================================== > ============= > To unsubscribe: mailto [EMAIL PROTECTED] with body: > "signoff JSP-INTEREST". > For digest: mailto [EMAIL PROTECTED] with body: "set > JSP-INTEREST DIGEST". > > Some relevant archives, FAQs and Forums on JSPs can be found at: > > http://java.sun.com/products/jsp > http://archives.java.sun.com/jsp-interest.html > http://forums.java.sun.com > http://www.jspinsider.com > =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
