http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22226 Tomcat throws JasperException instead of NumberFormatException when parameter can't convert to bean property Summary: Tomcat throws JasperException instead of NumberFormatException when parameter can't convert to bean property Product: Tomcat 4 Version: 4.1.24 Platform: Macintosh OS/Version: MacOS X Status: NEW Severity: Normal Priority: Other Component: Jasper AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Tomcat throws a JasperException instead of NumberFormatException when an input parameter can't be properly converted to a bean property. This makes it impossible to write an application portably, since it has to catch a Tomcat-specific exception. My JSP: -------- <jsp:useBean id="bean" class="test.TestBean"> <jsp:setProperty name="bean" property="height"/> </jsp:useBean> <html> <head><title>Bean Test</title></head> <body> <p>The height is <jsp:getProperty name="bean" property="height"/>.</p> </body> </html> ---------- My bean: ---------- package test; public class TestBean { private int height; public void setHeight (int h) {height=h;} public int getHeight() {return height;} } -------- To test: invoke it with "?height=foo" . You'll get: org.apache.jasper.JasperException: For input string: "foo" at org.apache.jasper.runtime.JspRuntimeLibrary.internalIntrospecthelper(JspRuntimeLibrary.java:274) at org.apache.jasper.runtime.JspRuntimeLibrary.introspecthelper(JspRuntimeLibrary.java:220) at org.apache.jsp.index_jsp._jspService(index_jsp.java:54) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:210) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) ... root cause org.apache.jasper.JasperException: For input string: "foo" at org.apache.jasper.runtime.JspRuntimeLibrary.convert(JspRuntimeLibrary.java:185) at org.apache.jasper.runtime.JspRuntimeLibrary.internalIntrospecthelper(JspRuntimeLibrary.java:268) at org.apache.jasper.runtime.JspRuntimeLibrary.introspecthelper(JspRuntimeLibrary.java:220) at org.apache.jsp.index_jsp._jspService(index_jsp.java:54) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:210) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) ... --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
