Re: tomcat 4.1 displays a blank page when compiling a JSP with compilation errors
Hi Christos, Quick Question for you. Does your JSP page have an include in it? Example: Login.jsp This page includes another jsp page called LoginForm.jsp. Does your jsp page have this? If so, I've noticed that my pages will show up blank if there is an error, where there is an include. Is this your situation? If so... because you are developing, the easiest way would be to call the include jsp directly (http://localhost/xxx/LoginForm.jsp). This will then give you the error in the browser. I've noticed this in tomcat, as well as Java Web Server when i first used that ages ago... Hope this helps, ...Robin - Original Message - From: Christos Karras [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, November 18, 2002 1:49 PM Subject: tomcat 4.1 displays a blank page when compiling a JSP with compilation errors On one of our Tomcat 4.1.12 servers, when someone requests a JSP page that has compilation errors, he gets a blank page instead of getting a tomcat generated page showing the compilation error. So we have to look in tomcat's logs to get the error message. That's nice for a production server, but I would like to have errors directly in the browser when developping. How can I enable error messages to be sent to the browser? Is hiding the error pages the normal default behavior? I have some Tomcat 4.1.12 servers (one per machine, development done on NT and production servers on linux) which have always sent jsp compilation error messages to the browser by default, while others only write the messages to logs. I tried the following: - set debug=1 to everything which has a debug parameter in server.xml - set jasper's logVerbosityLevel init-param to DEBUG (and left default values for other parameters) but still no error message shown in browser. Am I missing something in the documentation?

Re: Large pages not completely displayed with IE 5.x and Tomcat 4 .0.x
Hi, I had the same problem as you did... One of my pages would not completely load... Using: Tomcat 4.02, j2sdk1.4. Windows 2K/NT, doesn't matter.. happens on both. At first I thought that it was because it was large. But it wasn't the problem. The page in question returned about 150K of html code. Another page returned 600K and that ALWAYS displayed in its entirety. So, after some checking and testing, i discovered it is because i had too many objects open. (Instantiated objects galore). One thing i did to make it work is to make sure that each object that i instantiate is opened ONCE... (I use a java mapping strategy to get data from the database). Once i did that, the rest of the data would show up with no problem... That is one thing i would check and see if there are too many objects being instantiated (same ones all the time). That's my suggestion. Good luck, If that's not it, then i'm not sure what else it could be. :) ...Robin - Original Message - From: Michael Gerdau [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Tuesday, March 12, 2002 7:08 AM Subject: RE: Large pages not completely displayed with IE 5.x and Tomcat 4 .0.x I think an obvious first couple of questions: 1. Is the page competing execution or is it throwing an exception or perhaps hanging up due to deadlock? Not that I'm aware of. I get the effect by simply logging onto the webapp from a different machine immediately after starting tomcat. No concurrent users on Tomcat. This happens both with HTTP/1.1 on port 8080 and HTTP/1.0 on 8082 (both using the default configuration as of server.xml) 2.

I have the following problem: I'm running Tomcat 4.0.x (x == 1, 2 or 3) standalone on a Win2000 machine. I have a WebApp (written with Struts) that accesses a RDBMS and creates pages which occasionally are 100+ kB in size. This takes some time (between 20-50 seconds).

When I'm trying to access those pages from another machine within the local network (e.g. the production environment) some of these pages don't display completely. Examining the HTML inside the browser reveals they are indeed incomplete. What could cause this ? What additional info would be needed to debug this ?

He was unable to log into our site using Internet Explorer 5 on OS 9. We still had an instance on a development machine that used Tomcat 3.3, on which he experienced no problems. It appears that his session is never getting established at all -- my first thought was that he might have cookies disabled (I do not do URL rewriting currently, although that would probably fix the problem). After having him try our Tomcat 3.3 instance, it was clear that cookies are enabled, so that isn't the problem. My only other thought is that the JSESSIONID is a lot larger on Tomcat 4 -- is it possible that Mac IE5 cannot accept cookies that are longer than a certain amount?

Re: integer value
I assume that these fields are coming from a form from a previous page (ie:
html/jsp)... And that you are submitting this information to a servlet, or
another jsp page.
One thing you are missing when testing for null is that, when coming from a
previous page, it may not be null, but BLANK (ie: ). You need to test for
both ...
if (number == null || number.equals())
OR
if (name == null || name.equals())
But because it is strictly a number, you need to convert the number field
to a pure integer # to test for a number.
int iNewNumber = Integer.parseInt(number);
Doing it this way allows you to make sure you don't have a null # because
Integer.parseInt will convert a string to a 0.
The code that has number = 00; cannot happen because it is assumed
number is a String, and you can't convert int to String.
I hope this helps... You can email me directly if you need more help with
this.

Hi,
I have a doubt, I have a form that has name and his phone number, both
the fields are optional. I declared name as VARCHAR and number as
INTEGER in my SQL database. When the user leaves the fild empty, I get
an error with the number field as NumberFormatException.
So , What I need to do now is, when the user leaves the field null or
blank, I wanted to insert a default value into the database. For eg.
If(number == null)
{
number = 00;
}
if(name==null)
{
name=tomcat;
}
I know the number if statement will give error.But could you please help
me with this?

case it seems as though the jsp:forward is in some way causing the
behavior.
If anyone else has run across this situation, I would definitely like to
know what is going on and how to resolve this issue.
I'm also using IE 5.x, tomcat 3.2.x and linux. If code is needed, I'll
have to send tomorrow.
Thanks in advance

Well, that depends on which code you would like to see? The login code is
pretty basic...
Here's is my validateLoginServlet...
I am using a type4 jdbc driver (thinweb.tds driver).
import Common.dbfiles.*;
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ValidateLoginServlet extends HttpServlet
{
public void service(HttpServletRequest req, HttpServletResponse res)
throws IOException
{
String errorCode = ;
try
{
// get a connection
Class c = Class.forName(com.thinweb.tds.Driver);
Connection dbConn =
DriverManager.getConnection(jdbc:twtds:sqlserver://[removed];user
=[removed]
;password=[removed];TDS=7.0);
// instantiate data objects
DBCustomersSet customersSet = new DBCustomersSet(dbConn,Customers);
//DBCustomers customers = new DBCustomers();
// Now set the where clause to get the member (using setFilter)
customersSet.setFilter(LoginID=' +
req.getParameter(LoginID) + ');
Vector customersQuery = customersSet.query();
//Create a session.
HttpSession session = req.getSession(true);
//Now let's see if any records were returned.
if (customersQuery != null !customersQuery.isEmpty())
{
customersSet.firstRecord();
//DBCustomers cust = (DBCustomers) custSet.record();
DBCustomers theCustomer = (DBCustomers) customersSet.record();
//DBCustomers theCustomer = (DBCustomers)customersQuery.elementAt(0);
//Now we want to check the password.
if (theCustomer.getPassword().equals(req.getParameter(Password)))
{
session.setAttribute(theCustomer,theCustomer);
errorCode = 0;
System.out.println(UserID: + theCustomer.getLoginID() +
has logged in.);
customersSet.userLoggedIn();
}
else
{
//Wrong password, set the errorCode to 1.
errorCode = 1;
}
}
else
{
//Not found, set the errorCode to 2.
errorCode = 2;
}
session.setAttribute(errorCode,errorCode);
//System.out.println(ValidateLoginServlet errorCode: + errorCode);
dbConn.close();
}
catch (SQLException sqle)
{
System.out.println(Sql Exception: + sqle);
}
catch (ClassNotFoundException cnfe)
{
System.out.println(cnfe);
}
catch (ArrayIndexOutOfBoundsException aioobe)
{
System.out.println(aioobe);
}
}
}
In this case, it shows userid has logged in. At times it will do it
just
once, but other times it will do it twice... Did i add something in here
that shouldn't be?
Thanks.

Robin, there is no way to have any clue why this is happening without
seeing the code. Micael

Sharing Session between frame jsp's
Hi, This is how it works. I have a frame page with two frames (left.jsp and main.html). On the left, the user can login on the main frame by clicking on login (from the left.jsp). They can log in just fine. Session is created in the main frame. No problem. Problem is, I want to get the same session on the left frame so i can get their user information. Is there any way to make this possible? I've tried a few ways to share between the two frames, but nothing works in that regards. Does anyone have any ideas? Thanks. ...Robin -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Excel Problem
There doesn't seem to be a lot of requests about this problem that I am
having with Tomcat.
I am running tomcat 4, with jdk1.31_01.
I have an Excel file (called ULSExcel in the odbc source) as a default file.
I was able to change it so that when i copy the default file to a new file
name (LoginID.xls), i can change the file it refers to in the ULSExcel to
the new file (ULSExcel;dbq=LoginID.xls). This has worked previously with
tomcat 323 as well as JWS. This is the error I get.
Here's the set of the data source name:
ULSExcel;dbq= + excelFile + ;DriverID=22;READONLY=false
Here's another variation i tried...
{Microsoft Excel Driver (*.xls)};dbq= + excelFile +
;DriverID=22;READONLY=false
And here's the error I get in both cases.
[Microsoft][ODBC Driver Manager] Data source name not found and no default
driver specified
If I just use ULSExcel as my data source name, I get no problems
whatsoever. It saves it to the default file. Which is not what I wish to
do.
Considering the fact that this DID work prior to tomcat 4, does anyone have
any idea why this happened, or if there is another way to try and get this
to work?
Thanks to anyone who can help me out.
