Bom gente, estou a algum tempo mexendo em um ambiente web e ontem me deparei com um problema que creio ser besta, mas que não resolvi graças a minha inexperiencia com o TomCat. O problema é simples, tenho uma JSP que i…

isso ta me parecendo problema de import cara…sei la talvez vc nao tenha colocado o caminho completo do pacote pacote.app.suaclasse…

<%@page import = "TOOL.GAG.BUSINESS.*,java.util.*, UTILITY.*,DATABASE.*,COPSE.*, java.sql.*"%>

<jsp:useBean id="GAGPieJFC" scope="session" class="TOOL.GAG.BUSINESS.GAGPieJFC" />

Como vocês podem ver no code acima…

A exception que o Apache gera é…

org.apache.jasper.JasperException: Unable to compile class for JSPerror: Invalid class file format in C:\CopseWeb\jakarta-tomcat-4.0.4\webapps\ROOT\WEB-INF\classes\TOOL\GAG\BUSINESS\GAGPieJFC.class. The major.minor version ‘48.0’ is too recent for this tool to understand.

Eu dei uma pesquisada e me falaram que é sobre o meu JDK…
E que era necessária a instalação de um patch na pasta ROOT_JAKARTA/Commons/lib do jar “tools”. Que eu não consigo encontrar de jeito nenhum…

Please, Help!

acabei de mudar a JDK no meu JAVA_HOME para a versão 1.5

e tive uma mudança nas Exceptions
de 4 agora só tenho 2…

org.apache.jasper.JasperException: Unable to compile class for JSPerror: Invalid class file format in C:\Arquivos de programas\Java\jdk1.5.0_07\jre\lib\rt.jar(java/lang/Object.class). The major.minor version ‘49.0’ is too recent for this tool to understand.

Bom… to correndo atrás pra entender esse 2 erro da exception
Mas pelo visto ele já consegue compilar as minhas JSP.
O que é um alívio :?
Entretanto surgiu 2 novos…
rt.jar
e
Class java.lang.Object not found in class javax.servlet.GenericServlet.
package org.apache.jsp;

Ajudem este desesperado
