The class and TLD compiled fine, but after putting a test tag in my JSP page, Tomcat displays the following exception: exception javax.servlet.ServletException: javax.servlet.jsp.tagext.TagInfo.<init> (Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljavax/ servlet/jsp/tagext/TagLibraryInfo;Ljavax/servlet/jsp/tagext/TagExtraInfo; [Ljavax/servlet/jsp/tagext/TagAttributeInfo;Ljava/lang/String;Ljava/lang/String; Ljava/lang/String;[Ljavax/servlet/jsp/tagext/TagVariableInfo;Z)V org.apache.jasper.servlet.JspServlet.service(JspServlet.java:244) javax.servlet.http.HttpServlet.service(HttpServlet.java:853) com.cetacademicprograms.servlets.StudentAppFormServlet.dispatchToUrl (StudentAppFormServlet.java:249) com.cetacademicprograms.servlets.StudentAppFormServlet.actionDefaultHand ler(StudentAppFormServlet.java:149) com.cetacademicprograms.servlets.StudentAppFormServlet.doGet (StudentAppFormServlet.java:81) javax.servlet.http.HttpServlet.service(HttpServlet.java:740) javax.servlet.http.HttpServlet.service(HttpServlet.java:853) root cause java.lang.NoSuchMethodError: javax.servlet.jsp.tagext.TagInfo.<init> (Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljavax/ servlet/jsp/tagext/TagLibraryInfo;Ljavax/servlet/jsp/tagext/TagExtraInfo; [Ljavax/servlet/jsp/tagext/TagAttributeInfo;Ljava/lang/String;Ljava/lang/String; Ljava/lang/String;[Ljavax/servlet/jsp/tagext/TagVariableInfo;Z)V org.apache.jasper.compiler.TagLibraryInfoImpl.createTagInfo (TagLibraryInfoImpl.java:435) org.apache.jasper.compiler.TagLibraryInfoImpl.parseTLD (TagLibraryInfoImpl.java:248) org.apache.jasper.compiler.TagLibraryInfoImpl.<init> (TagLibraryInfoImpl.java:162) org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:418) org.apache.jasper.compiler.Parser.parseDirective(Parser.java:483) org.apache.jasper.compiler.Parser.parseElements(Parser.java:1539) org.apache.jasper.compiler.Parser.parse(Parser.java:126) org.apache.jasper.compiler.ParserController.doParse (ParserController.java:220) org.apache.jasper.compiler.ParserController.parse (ParserController.java:101) org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:203) org.apache.jasper.compiler.Compiler.compile(Compiler.java:470) org.apache.jasper.compiler.Compiler.compile(Compiler.java:451) org.apache.jasper.compiler.Compiler.compile(Compiler.java:439) org.apache.jasper.JspCompilationContext.compile (JspCompilationContext.java:511) org.apache.jasper.servlet.JspServletWrapper.service (JspServletWrapper.java:295) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) javax.servlet.http.HttpServlet.service(HttpServlet.java:853) com.cetacademicprograms.servlets.StudentAppFormServlet.dispatchToUrl (StudentAppFormServlet.java:249) com.cetacademicprograms.servlets.StudentAppFormServlet.actionDefaultHand ler(StudentAppFormServlet.java:149) com.cetacademicprograms.servlets.StudentAppFormServlet.doGet (StudentAppFormServlet.java:81) javax.servlet.http.HttpServlet.service(HttpServlet.java:740) javax.servlet.http.HttpServlet.service(HttpServlet.java:853) Some other newsgroups claim that this looks like a JAR file version mismatch. I downloaded the Tomcat installation from the jakarta.apache.org website and have not added any new JARs. This was not an upgrade. Can someone please look into this?
