Problems JSP / Tomcat
Hello,
When I create a new JSP page, I have error message about the compiler Tomcat, Jasper.
Nevertheless, when I use the JSP pages of Tomcat, I have not problem. Why ? Must I configure Jasper. If yes, how ?
Thanks a lot,
[email protected]
More likely there is a syntax error in your JSP that is preventing it from compiling. Please post the error message.

Session problems in tomcat 5.0.28
Even I shutdown the tomcat 5.0.28 server the session variable is still existing and it is showing the old values. What I have to do to disable the old values? Is it the problem with tomcat 5.0.28 or with JSP coding!
Tomcat serializes sessions to the hard drive when it shutsdown. If you don't want this you have three choices:
1: you can disable this functionality in the server.xml. Check the documentation.
2: you could just delete the session.ser file when you shut down tomcat. This file is under work/standalone/{webapp name}
3: you could close and re-open the browser so that the old jsessionid will not be sent and a new session will be created. The old session will eventually time out.
The third option is probably the easiest. -
Catching jsp/tomcat/java SQL error
I have been trying to get the sample code to work from an old book. I was finally able to get it to run under tomcat 4.1.31 but there is one bug I just cannot figure out how to handle. I am a beginner to Java/JSP/Tomcat and have about 16+ hours invested in this problem so far.
The delFruit.jsp calls methods from FruitConnect.java.
I found that if the fruit chosen for deletion was not involved in a referential integrity link to a FruitMonth file the code works fine. But if it is linked the delFruit.jsp just displays a blank screen and nothing is deleted. It is fine for it not to be deleted but I cannot find anyway to handle it. I tried to add the checkFruitForSale bandaid below but it causes me a blank screen as well.
Any help would be appreciated.
It would be great if I could just see what is happening when FruitConnect is processing code. I get no errors, just a blank screen. I'm going to try using NetBeans and their debugger next.
Here is delFruit:
<%@ page import="java.sql.*" %>
<jsp:include page="adminHeader.html" flush="true" />
<jsp:useBean id="fruitConnect" class="fruit1.FruitConnect" />
<%
String msg = "The following fruits have been deleted:<br> ";
//Build the list of fruits to delete
String delFruit[] = request.getParameterValues("delFruit");
//WE WILL ONLY GET CHECKBOXES THAT WERE CHECKED
String fruitList = "";
if (delFruit != null){
int len = delFruit.length;
fruitConnect.dbConnect();
for (int i = 0; i < len; i++) {
String passfruit = delFruit;
if (fruitConnect.checkFruitForSale(passfruit)) {}
else{
fruitList = fruitList + "'" + delFruit[i] + "',";
msg = msg + delFruit[i] + "<br>";
out.print(msg);
out.print(msg);
fruitList = fruitList + "'nonsense'";
if (fruitConnect.deleteFruit(fruitList) < 1) {
msg = "There was an error deleting the fruits from the database.";
else{
msg = "Deletion was successful";
fruitConnect.dbDisconnect();
else {
msg = "You must select some fruit to delete.";

It would be great if I could just see what is happening when
FruitConnect is processing code.For that sort of thing, you want to use a logger. Either Log4J or the standard Java1.4 logger would help. Basically configure it to log statements to file as your program runs.
I get no errors, just a blank screenThat could indicate that the page ran enough to fill up the page buffer, and then failed. When you view source, do you see anything on the page at all? -

How to combinate JSP+Tomcat+mysql??
Hi,guys. My question is as the above subject.
I have installed JDK, Tomcat, mysql, and my OS is WinXP, I am trying to develop a JSP site in my computer.
For JDK, the commands javac, java, ...... work OK;
For Tomcat, http://localhost:8080 works OK, meaning the cat page appears.
For mysql, I can login, and sql statements work OK;
And I download mysql-connector-java-3.1.8a.
What I should do further to combinate JSP+Tomcat+mysql, so my JSP site can work? Any advice?
I need help.
Thanks in advance!Thanks,duffymo!
As you said, I am learning more about those things.
Actually I am trying to open a JSP webpage to show the connection JSP+Tomcat+mysql works OK.
I copied the mysql-connector-java-3.1.8-bin.jar to ...Tomcat 5.0\common\lib,
created a datebase, named test in MySQL, and wrote a JSP as the below:
<%@ page contentType="text/html; charset=gb2312" %>
<%@ page language="java" %>
<%@ page import="com.mysql.jdbc.Driver" %>
<%@ page import="java.sql.*" %>
<%
//driver
String driverName="com.mysql.jdbc.Driver";
//username
String userName="test";
//code
String userPasswd="123";
//database
String dbName="test";
//table name
String tableName="mytab";
//connection string
String url="jdbc:mysql://localhost/"+dbName+"?user="+userName+"&password="+userPasswd;
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
String sql="SELECT * FROM "+tableName;
ResultSet rs = statement.executeQuery(sql);
ResultSetMetaData rmeta = rs.getMetaData();
int numColumns=rmeta.getColumnCount();
// output
out.print("id");
out.print("|");
out.print("num");
out.print("<br>");
while(rs.next()) {
out.print(rs.getString(1)+" ");
out.print("|");
out.print(rs.getString(2));
out.print("<br>");
out.print("<br>");
out.print("successful!");
rs.close();
statement.close();
connection.close();
%>
How can I test the connection JSP+Tomcat+mysql works OK?
Thanks again! -
I'm using Linux with Tomcat 4.0. I found that the counter of session has something wrong. The time counter is not reset when the user access the session.
I try to use Tomcat 3.2.3 and my programs work fine. Is this the problem of Tomcat 4.0 ? anyone have the same problem ?
plse, help.I'm using Tomcat 4.0 and Linux.
I have a problem about the session.
timeout = 600;
session.setMaxInactiveInterval(timeout);
...When the user active the session, the "timeout" should be reset to 600. In fact, the session is still die even the user active the session.
And this problem does not occurred in Tomcat 3.2.3.
I guess is the bug of Tomcat 4.0.
Is anyone use Tomcat 4.0 and Linux. Can anyone help me to check the timer of session is correct or not ?
Thank you !
Tomcat 3.2.3 is ok.
The problem occurred in Tomcat 4.0.1 and 4.0.2.
Please help ! -
Problems with Tomcat & Eclipse on MacOSX
Hi everybody. I have a problem with Tomcat and Eclipse. I must make an application with JSF for my dissertation and i even become a new Mac user so i have some problems. I have installed Eclipse 3,3 Europe on Mac OSX 10,4, also I have installed Tomcat 5,5 setting up environment variable and users of Tomcat. Well, when I try to connect them creating a new server in Eclipse and select Tomcat as server and relative folder of origin, the problems begin. When I try to run on server a JSF project(naturally I have imported all the necessary libraries) it give this error to me: Could not load the Tomcat incomplete serveur configuration at /Servers/Tomcat v5.5 serveur at localhost-config.The configurator mau be corrupt or. Reason: Could not load the Tomcat incomplete serveur configuration at /Servers/Tomcat v5.5 serveur at localhost-config.The configurator mau be corrupt or incomplete. On what it can depend? It is possible that is a JRE problem? I do not find the folder jre on my file system(are novice with the mac). Thanks to all.
This seems like a question that would be better put to an Eclipse forum.

Im having problems getting tomcat to work in IE6 in Windows XP. Following the set of instructions i have, i successfully managed to configure tamcat 3.2.3 in windows 2K and IE5.5, but now i have put XP on, i cant get it to work using the same proceedure. In 2K, when i typed http://localhost i got a tomcat page some up. in XP i just get a blank page saying "Directory Listing for:/ Tomcat Web Server v3.2.3". when ive tried out a few of the examples, i cant get them to work properly either. Is there something i should have done differently for XP/IE6 ??
Any help greatly appreciated. thanksType in http://localhost:8080/
Tomcat also caches webpages in the work folder. Delete this folder and restart tomcat.
Also make sure that web.xml points to the right files.
In IE, go to Tools -> Internet Options -> Click Settings and make sure that the 'Every visit to page' radio button is checked. -

Problems with Tomcat 4.0 and jdk 1.3.1 (jsp:include) Help Gurus...
Im running examples of the include:
<jsp:include page="xxx.jsp" flush="true">
and received error:
org.apache.jasper.JasperException: No se puede compilar la clase para JSP
An error occurred at line: 17 in the jsp file: /jsp/include/include.jsp
Generated servlet error:
/Programas/Tomcat4/work/localhost/examples/jsp/include/include$jsp.java:79: Method include(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.String, javax.servlet.jsp.JspWriter, boolean) not found in class org.apache.jasper.runtime.JspRuntimeLibrary.
JspRuntimeLibrary.include(request, response, "/jsp/include/foo.html" + jspxqStr, out, true);
^
Please Help me Im running this equal with:
<%@ include file="xxx.jsp" %>
and runnig fine....The two means of including files are different in their approach.
Using <jsp:include .../> compilation of the included jsp is done at run -time not during compilation.
Using <%@ include .../> compiles at compile time.
Looking at the error it seems that the method JspRuntimeLibrary.include is not being found which suggests that you may have a classpath problem. Check that there is not a servlet.jar in the classpath that is from a earlier spec than the one provided with Tomcat.

Tomcat config problem: jsp can't find a bean class
I've been working within a JSP/Javabeans/JDBC/MySQL architecture with Windows XP and Websphere. So far everything works perfectly. Now I need to get the same project and make it run with a Tomcat server.
I've already set the Tomcat server but its not working properly. I have a problem when a jsp tries to access any class inside my project's package.
For example, when I make the next call:
<jsp:useBean id="ctrl" class="myPack.myBean" scope="page"/>
I get an error saying:
Error: 500
Location: /myproj/login.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile C:\Program Files\jakarta-tomcat-3.3.1\work\DEFAULT\myproj\login_1.java:64: Class myPack.myBean not found.
myPack.myBean ctrl = null;
^
I believe that my problem cames when setting the Tomcat environment. So far what I have done is:
* install j2sdk-1.3.1.03
* install jakarta-tomcat-3.3.1
* install mysql-max-3.23.51-win
* set the environment variable JAVA_HOME
* set the environment variable TOMCAT_HOME
* set the environment variable MYSQL_HOME
* add the %JAVA_HOME%\bin to the PATH
* create 'myproj' directory inside TOMCAT_HOME\webapps
* create into 'myproj' the subdirectory WEB-INF\classes and copy into it the jar file with my java classes (myPack.jar).
* copy into TOMCAT_HOME\lib\apps the JDBC driver for MySQL.
* copy my project files (jsp, html, images, etc.) and its structure into 'myproj' directory.
I haven't include anything into the CLASSPATH because so far I've read that Tomcat will automatically include all the classes that are inside the directories TOMCAT_HOME\myproj\WEB-INF\classes and TOMCAT_HOME\lib\apps.
I really don't have a clue about what I'm doing wrong. I'd apreciate if anyone can help me out with this one ;) ... I thank you in advance!Hi, it's me again!.
Since nobody replied to me I'm replying myself :D
Ok, seriously is just to let you know that I have solved my problem and I would like to tell you how I solved it ... somebody might be doing the same mistake than I was doing and could found this helpful. I just forgot to mention that I was using Tomcat 3.3.
Well, first of all let me tell you that there was nothing wrong with the previous configuration that I post in my first message. Everything is ok except that in the TOMCAT_HOME\webapps\myproj\WEB-INF\classes directory I was putting my classes as a jar file, so I deleted it and instead I put the directory myPack with its unpacked class files. THIS SOLVED MY PROBLEM!!!
First I was trying to do some complicated things editing bat and xml files, but as a matter of fact I found it's quite simple. Furthermore, I was really surprised by the performance of Tomcat. I'm relly happy for that !! ;)
Hope it works for you,

What is wrong ?
I have Windows NT and Tomcat 5 (from jwsdp 1.2).
Thank you,
Alex.I just tried to reproduce the problem with old version of Tomcat (4.0.2) and ... it works. It is definitely specific for Tomcat 5 (or may be one of the late Tomcat 4 as well). There is another related difference:
With Tomcat 4 I could create javabean in class subdirectory (default package) and use
<%@ page import="ex01" %>
Now with Tomcat 5 I have syntax error in this line.
This syntax error disappeared when I moved javabean into package pack01. -

Hope is only the love of life.hi,
FIrst make one thing clear. By classes.jar you mean either classes111.jar or classes12.jar.Right?If not,please check tht.
Also,u needn't set any classpaths for Tomcat.

Eclipse problem with Tomcat when running jsp
when I start tomcat from CMD, it starts normally and display http://localhost:8080/ properly
but when I start tomcat from Eclipse, it starts the server normally,
but it can't display http://localhost:8080/ properly,
I guess that the problem with the java classpath isn't defined correctly in Eclipse
but but I've tried it before, and it doesn't work
