If I were passing the INTEGER ARRAY alone that might have worked fine.
I am passing 4 parameters. One of them is an INTEGER ARRAY.
Here is the code that I have:
private String getValuePairString(String name, String value, boolean addAmpersand) { StringBuffer valuePair = new StringBuffer(); if(addAmpersand) valuePair.append(name).append("=").append(value).append("&"); else valuePair.append(name).append("=").append(value); return valuePair.toString(); } private String getValuePairStringForArray(String name, Array reportNums[], boolean addAmpersand) { System.out.println("You have invoked method with Array Object in it.."); StringBuffer valuePair = new StringBuffer(); if(addAmpersand) valuePair.append(name).append("=").append(value).append("&"); else valuePair.append(name).append("=").append(value); return valuePair.toString(); } public String sendRequest(String beginDate, String endDate, String custType, int reportNumbers[]) { try { StringBufferparameterStringBuffer = new StringBuffer(); parameterStringBuffer.append(getValuePairString("beginDate", beginDate, true)). append(getValuePairString("endDate", endDate, true)).append(getValuePairString("custType", custType, true)); parameterStringBuffer.append(getValuePairStringForArray("reportNumbers", reportNumbers[], false)); URL url = new URL(SERVER_URL + SERVLET_URL); URLConnection conn = url.openConnection(); conn.setDoInput(true); conn.setDoOutput(true); conn.setRequestProperty(_TYPE, _ENCODING); BufferedWriter out = new BufferedWriter( new OutputStreamWriter(conn.getOutputStream())); out.write(parameterStringBuffer.toString()); parameterStringBuffer.toString(); out.flush(); out.close(); BufferedReader in = new BufferedReader( new InputStreamReader(conn.getInputStream())); String responseLine = in.readLine(); StringBuffer response = new StringBuffer(responseLine); while (responseLine != null ) { response.append(responseLine); responseLine = in.readLine(); } in.close(); return response.toString(); } catch (MalformedURLException me) { System.out.println("Error occured while processing the URL connection"); me.printStackTrace(); return "MalformedURLException - ERROR"; } catch (IOException ioe) { System.out.println("Error occured while processing the URL connection"); ioe.printStackTrace(); return "IOException - ERROR"; } }

Hi,
I have a standalone client which invokes a Servlet.
I want to send an INTEGER ARRAY as a parameter to the Servlet. Can I do that?
If so, can anybody show me how??
Thanks

Yeah, you are correct. I was trying all different things to debug it.
OK..here it is. I am pasting a part of the main page. The main page doesn't have any JSP in it.
<%! String logout = "true"; %>
<table width="90%" height="80%" border="0" cellpadding="0" cellspacing="0" bordercolor="#003399" >
<tr>
<td height="31" align="center"><a href="LogOut.jsp?logout=<%=logout%>" ><font color="#FFFFFF" size="2" face="Verdana, Arial, Helvetica, sans-serif">Log Out </font></a></td>
</tr>
Thanks.

Please Phil, Do POST IT. I am right now, at the end of developing my application in JSP, TomCat4.1.18 and MySQl with JavaBeans.
I would like to host the application in IIS environment.
Thanks

I have a web application developed in JSP, TomCat 4.1.18.
In the application, I am logging a user and setting the userId in the session. After the user does whatever he needs to do, he would click on LogOut.
In the LogOut.jsp, I have the following code.
<%@ page language= "java" %>
<%@ page import="javax.servlet.http.HttpSession" %>
<%
if(request.getParameter("logout")!=null){
out.println("called Me");
session.removeValue("loginid");
session.removeValue("isadmin");
session.invalidate();
}
response.sendRedirect("login.jsp");
%>
My problem is that 'login.jsp' is never being called. Instead, it's staying on the screen from where I clicked 'LogOut'.

Can any body help me?? :roll:

Well, (I am a newbie) The only reason I put my question here was..
I am using Tomcat AppServer. I did not know if I needed to make any configuration changes too...
(even now, I am not sure if I have to make configuration changes. I guess I need not..)
thanks,

Could you please show me as an example??
Thanks.

I have web application on TomCat 4.1.18. I am using a couple of images in my application.
I am setting the 'img' tags' src property as an absolute path..like:
file:///E:\folder1\images\sample_logo.gif

I want to use a relative path. How is it possible?
Please indicate if I need to make any configuration changes? OR
Is it only a change in the SRC attribute of IMG tag

Hi All,
I am new to this. I am trying to write a simple application in JSP to access MySQL on TomCat4.1.18.
I have downloaded the MySQL JDBC Driver from www.sourceforge.net/projects/mmmysql/.
I have copied the mm.mysql-2.0.14-bin.jar into 'lib' directory under my TomCat Default installation directory (E:/jakarta-tomcat-4.1.18/server/lib).
I have written this JSP :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> Employees List </TITLE>
</HEAD>
<@ page import="java.sql.*" %>
<BODY>
<TABLE border=1 width=75%>
<TR><TH>Last Name</TH><TH>First Name</TH></TR>
<%
Connection conn = null;
Statement st = null;
ResultSet rs = null;
try
{
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://localhost/cartapp");
st = conn.createStatement();
rs = st.executeQuery("select * from employees");
while(rs.next()){
%>
<TR><TD> <%= rs.getString("lname_txt") %> </TD>
<TD><%= rs.getString("fname_txt") %> </TR>
<%
}
%>
</TABLE>
<%
}catch(Exception ex) {
ex.printStackTrace();
%>
</TABLE>
Ooops, Something bad happened:
<%
}finally{
if(rs != null) rs.close();
if(st != null) st.close();
if(conn != null) conn.close();
}
%>
</BODY>
</HTML>

I have included the Context Path information in the 'server.xml' file.
<Context path="/JSPTestSamples" docBase="E:\JSPTestSamples" debug="1"
reloadable="true" crossContext="true"/>
When I execute in the browser, I get
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 10 in the jsp file: /employees_list.jsp
Generated servlet error:
[javac] Compiling 1 source file
E:\jakarta-tomcat-4.1.18\work\Standalone\localhost\JSPTestSamples\employees_list_jsp.java:57: cannot resolve symbol
symbol : class Connection
location: class org.apache.jsp.employees_list_jsp
Connection conn = null;
^
I AM UNABLE to RESOLVE....

Can any OF YOU tell me what's wrong??

I have ONLY TOMCAT4.1.18 installed on my machine. My machine is Win2k and I am using for development purposes ONLY. I do not have any WebServer (like apache).
My question is...
Is it possible that I can install and use JSPSmartFile tool on my machine and USE it ONLY with TOMCAT?? (without Apache??)
if so, could anyone can show this particular installation setup?? (or give links. I tried in www.jspsmart.com. this seems to indicate that I need Apache..!!!)
Thanks a bunch

Thank You guys....I got it working. Now, I understand why it was not finding earlier.

Hi,
I am new to this. I am running TomCat4.1.18 version. I am trying to run a sample JSP.
I created a folder called "inc" in e:/jakarta-tomcat-4.1.18/webapps/ROOT/inc. I have included "index1.jsp" in this folder.
In folder e:/jakarta-tomcat-4.1.18/conf/server.xml file, I have added
<Context path="/inc" docBase="inc" debug="1" reloadable="true"/>
I restatred the server and
When I execute http://localhost:8080/inc/index1.jsp,
I get "HTTP:404" server error.
I am pretty sure, I am missing something here.... Please correct me..
Could ANYONE PLEASE HELP ME??
Thank You.

My code is pretty simple. When I execute http://localhost:8080/examples/jsp/num/numbguess.jsp, I am able to see the webpage.
Now, I have a sample JSP "index.jsp" in "jakarta-tomcat-4.1.18/webapps/inc/. I have modified the server.xml file with
<Context path="/inc" docBase="inc" debug="0"
reloadable="true" crossContext="true"/>
INDEX.JSP Code:
<html>
<head>
<style>p { font-family:tahoma; font-size:14pt; }</style>
</head>
<body>
<%
String name = "World";
%>
<p>Hello <%= name %>!</p>
</body>
</html>

I know I am missing some part of configuration. But I am unable to figure it out....

Thanks,
