http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7356 Jasper cannot find setter for Custom JSP Tag attribute 'returns' in Tomcat 4.0.3 Summary: Jasper cannot find setter for Custom JSP Tag attribute 'returns' in Tomcat 4.0.3 Product: Tomcat 4 Version: 4.0.3 Final Platform: PC URL: http://131.94.143.135:8080/cop4540/editall.jsp OS/Version: Linux Status: NEW Severity: Major Priority: Other Component: Jasper AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] For some reason, when trying to use Custom JSP Tag libraries with Tomcat 4.0.3 Jasper throws a CompileException complaining that the setter for the attribute named 'returns' cannot be found. The error does not occur in Tomcat 4.0, it used to compile and work properly on that version. The JSP page calls the tag as follows: <PC:SQLForEach returns="true" sql="SELECT Name FROM CHARACTERISTICS" connection="charconnection"> //content </PC:SQLForEach> The section of the TLD that defines the tag is: <?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_2.dtd";> <taglib> <!-- some stuff --> <tag> <name>SQLForEach</name> <tag-class>jsptags.SQLForEach</tag-class> <body-content>JSP</body-content> <description> some description here </description> <attribute> <name>returns</name> <required>false</required> <rtexprvalue>true</rtexprvalue> </attribute> <attribute> <name>sql</name> <required>true</required> <rtexprvalue>true</rtexprvalue> </attribute> <attribute> <name>connection</name> <required>true</required> <rtexprvalue>true</rtexprvalue> </attribute> <attribute> <name>maxCount</name> <required>false</required> <rtexprvalue>true</rtexprvalue> </attribute> <attribute> <name>minCount</name> <required>false</required> <rtexprvalue>true</rtexprvalue> </attribute> </tag> <!-- some stuff --> </taglib> The tag in question, SQLForEach, contains the methods: public void setReturns(boolean b) { //code } public boolean getReturns() { //code } The error has been replicated in Tomcat 4.0.3 on Linux Mandrake 7.0 (Intel Pentium II, 64MB RAM), Win98 (Intel Pentium2 233, 64MB RAM) and Win2K (AMD Duron 600, 128MB RAM). Included is the url of a JSP page that uses the tag.
