Subject TAG Lib problem
Date Mon, 02 Aug 2004 05:59:00 GMT
Hi all,

I have a problem with the Jasper compiler when I try to compile a JSP using
TagLibs.

The configuration is:

Tomcat 5.0.19, JSDK 1.4.2.

I have a simple application with:

.- 1 TLD:

	<tag>
		<name>Operacion</name>
		<tag-class>com.kutxa.kn.comun.tags.TituloOperacionTag</tag-class>
		<attribute>
			<name>MasInfo</name>
			<required>false</required>
		</attribute>
		<attribute>
			<name>Titulo</name>
			<required>false</required>
			<rtexprvalue>true</rtexprvalue>
		</attribute>
		<attribute>
			<name>Ancho</name>
			<required>false</required>
			<rtexprvalue>true</rtexprvalue>
		</attribute>
		<attribute>
			<name>Salto</name>
			<required>false</required>
		</attribute>
		<attribute>
			<name>VolverInicio</name>
			<required>false</required>
			<rtexprvalue>true</rtexprvalue>
		</attribute>

	</tag>



JSP:  With on reference to the TLD:
       <cod:Operacion Titulo="_T_DETALLE" Salto="false" VolverInicio="false">


JAVA TAG CLASS: With one attribute and method:
       - String Titulo
       - public void setTitulo(...){
         }
       - public String getTitulo(...){
         }


When the jasper compile the JSP I have one error:

    "...Unable to find setter method for attribute"


org.apache.jasper.JasperException: /jkn_opkn/tmpl/es/posglobal.jsp(433,0)
