Re: Web Server Crash
Hi Richard, I was in the same situation sometime back. Actually, there is ome bug in jdk1.2.2 because of which, the garbage collector attempts to collect some of the valid objects in memory. Try upgrading to jdk 1.3. I did that and the problem was resolved. Regards Ashish -Original Message- From: Boston Richard [mailto:[EMAIL PROTECTED]] Sent: Saturday, July 15, 2000 12:19 AM To: [EMAIL PROTECTED] Subject: Web Server Crash this question may be suitable for several list groups but I'll start here. I've got a very simple JSP file (A.JSP) that contains a link to another JSP file (B.JSP). B.JSP contains some Java Code that instantiates an object. (It is NOT bean oriented at this point, I just imported.) <% MyObject theObject = new MyObject(); %> some html code. NOTE: This is the only java code in the ServerPage at this point. After going back and forth between A.JSP and B.JSP a couple of times from A.JSP I get an error that java.exe has crashed and can't read memory. My configuration is as follows: Java Web Server 2.0 (patch included) using jdk1.2.2 If anyone has seen this before that would be great. thanks Richard === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

JSWDK server crashing...Urgent
Hi,
I am developing a site using JSPs and .java files (No beans being
created for now). The JSWDK server crashes after it executes and displays
Screen.jsp file (sequence shown below)
Environment:
NT 4.0, JDK 1.2.2, JSWDK 2.1
Scenario:
Login.jsp ---> Project.jsp ---> Screen.jsp ---> Control.jsp
As soon as a request for a JSP file is received by the web server,
it invokes the constructor in the respective .class file and creates a
connection to the SQL 7.0 database. The code for the Screen processing is
given for reference.
I am unable to find valid a reason for this. Has anybody ever faced a
similar situation...? Where am I going wrong?
//Code for processing screen.jsp file
public class WebPage
private Connection con=null;
private Statement stmt;
public WebPage() {
try {
getConnection();
if(con==null) {
msg("Connection for screen could not be
created...");
return;
}
} catch (SQLException e) {
System.out.println(e.getMessage());
}
}
private void getConnection() throws SQLException
{
try {
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:TEST";
con = DriverManager.getConnection(url);
} catch(Exception CNFE){
System.out.println(CNFE.getMessage());
}
}
protected void finalize() throws Throwable
{
if (stmt != null) {
try {
stmt.close();
} catch(SQLException ex) {
msg(ex.getMessage());
} catch(Exception ex) {
msg(ex.getMessage());
}
}
if (con != null) {
try {
con.close();
} catch(SQLException ex) {
msg(ex.getMessage());
} catch(Exception ex) {
msg(ex.getMessage());
}
}
}
//Other business specific methods go here...
}
Regards
Ashish

Re: Client side selection
I believe XML would be the best choice for this. Using XML, you can download the entire information(including Country-City relationship) at one go. This would help in three ways: 1. Eliminate the need to get back to the server for getting cities related to a country 2. No array manipulation needs to be done. 3. No need to reload the full page again.

mail using JSP
Hi, In my application being developed in JSP, I have a hyperlink for contacting the web admn. When the user clicks on the hyperlink, an outlook form should open. I have done this using the mailto tag. Now, as a next step, I would like the mail form to have the following fields filled in: 1. To: 2. CC: 3. Subject: 4. Body: I am able to open the mail form with all the fields filled in except the mail body. The text that should appear in the mail body should have blank lines between paragraphs. I am unable to insert blank lines in the body text. Does anybody have an idea as to how blank lines can be inserted in the body of a mail message.

Variable declaration
Hi, What is the difference in declaring the variables as %> Vs. <% %> as far as concurrent users are concerned.
