[JBoss-user] [Installation Configuration] - Re: package javax.servlet.jsp does not exist

2005-05-26 Thread nkkwok 
Komo, thank you for your advice.

After I have added the servlet.jar in my classpath, the mentioned problem was 
solved. My system variables now is set like this:

JAVA_Home: c:\Program Files\Java\jdk1.5.0_01 
JBOSS_HOME: C:\jboss-4.0.0

Path=c:\Program Files\Java\jdk1.5.0_01\bin 

Classpath=c;\ jboss-4.0.0\bin;C:\jboss-4.0.0\server\default\lib\servlet.jar

[JBoss-user] [Installation Configuration] - package javax.servlet.jsp does not exist

2005-05-09 Thread nkkwok 
I have encounter the following error when I compiled the Ex5AddTag.java which I 
put it under the following path:

C:\jboss-4.0.0\server\default\deploy\jsp.war\WEB-INF\classes

Error message:

Ex5AddTag.java:3: package javax.servlet.jsp does not exist

import javax.servlet.jsp.*;
Ex5AddTag.java:4: package javax.servlet.jsp.tagext does not exist
import javax.servlet.jsp.tagext.*;

Clearly, Java didn't find javax.servlet.jsp.* and  import 
javax.servlet.jsp.tagext.*. 

I understand that the javax.servlet package is not part of J2SE Java. I don't 
know how to get javac to use it and I don't know how to configure it to use 
include the javax.servlet .jar and the javax.servlet.jsp.tagext  in my 
classpath. 

I tried to add the following to my path, but it didn't work too:
C:\jboss-4.0.0\bin;C:\jboss-4.0.0\lib\servlet.jar;

Please advise and thanks in advance!


I checked that I have already have the following .jar files:
javax.servlet.jar
javax.servlet.jsp.jar
servlet.jar

C:\jboss-4.0.0\server\default\lib 

My computer environment as shown:

For your easy reference, the code of Ex5AddTag.java:

package it350;
  | 
  | import javax.servlet.jsp.*;
  | import javax.servlet.jsp.tagext.*;
  | import java.io.*;
  | 
  | public class Ex5AddTag extends TagSupport {
  | 
  | private int num1 = 0;
  | private int num2 = 0;
  | 
  | public int doStartTag() {
  | try {
  | JspWriter out = pageContext.getOut();
  | out.print(The sum of  + 
  |   num1 +  and  + 
  |   num2 +  is  +
  |   sum(num1, num2));
  | } catch (IOException e) {}
  | return (SKIP_BODY);
  | }
  | 
  | public void setNum1(int n1) {
  | num1 = n1;
  | }
  | 
  | public void setNum2(int n2) {
  | num2 = n2;
  | }
  | 
  | public int sum (int num1, int num2) {
  | return num1 + num2;
  | }
  | }

[JBoss-user] [Beginners Corner] - Jboss4.0_Jsp_page_errorPage_exception problem

%@ page isErrorPage=true %
  | Calculate2Error.jsp reported the following error:
  | I%= exception %/I.  
  | PA HREF=Calculate2.htmlClick here to try again/A

My problem:

One of the response of the above codes are like this:
When the calculate2html file is displayed on the browser, 
suppose when not entering any value or non-integer value 
in the input box, the Calculate2Error.jsp will be called via
 Calculate2.jsp to display exception error 
message: java.lang.NumberFormatException: null 
or any wrong input like:abcd

But we I do so, I got the following error reported:

ERROR:
Condition: When not puting value on Value1 text box...as shown:

http://localhost:8080/jsp/Calculate2.jsp?Value1=Value2=6

Result: The page cannot be displayed
 HTTP 500 - Internal server error
 Internet Explorer

Please advise why such problem occurs or any idea on the possible cause of it.
