PreparedStatement Unicode MySQL
Hi, I am having trouble inserting and retrieving Asian characters in my MySQL DB using PreparedStatement. I have set up my table thus: CREATE TABLE `messages` ( `id` int(10) unsigned NOT NULL auto_increment, `message_body` text NOT NULL, `sender_number` text NOT NULL, `shortcode` text NOT NULL, `image` longblob, PRIMARY KEY (`id`) ) CHARACTER SET utf8 TYPE=MyISAM; and am inserting using a PreparedStatement - pstmt.setString(indexOfColumnInQuestion, asianTextString); to insert in to message_body. However, when viewing the column in the query browser, and retrieving it from a ResultSet, it reads ? ??? and so on (I am attempting to insert Thai characters in this instance). Is there a method of PreparedStatement I am missing? thanks and regards Paul. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
io.File relative path constructor
Hi, A should-be easy one - I do not wish to define an absolute path to a File as it will packaged in a JAR, therefore its path will change. How do I construct a File relative to my src root, something like File file = new File(/path/myFile.xml);? I tried passing in a URL, URI but am getting: Exception in thread main java.lang.IllegalArgumentException: URI is not hierarchical when I jar and run it. Am using Win XP + Java 1.5.

Input stream
Hi All, I have a socket receiving streams of XML. I receive an InputStream, but short of a dirty hack, do not know when (or how) I pass the stream/contents to be parsed. Any thoughts/resources on parsing streaming XML please? Thanks Paul.
RE: Input stream
Hi thanks, Parsing a file would not normally be a problem, but as it is a stream, there is no EOF and when I parse the stream into: DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder(); db.parse(in); I get: org.xml.sax.SAXParseException: The processing instruction target matching [xX][mM][lL] is not allowed. What I have read on this message means invalid XML. And if there were no EOF that would be expected? I have tried parsing the simplest of XML files. This is my dirty hack - I can delimit the 'packet' with some obscure character while populating say a StringBuffer, write it to File, and re-parse it (I did say it was dirty;). A packet is the contents of a complete XML file which are sent randomly. So my problem is not the parsing, but capturing the fragment of an inputstream that will parse as valid XML. All input appreciated rgds Paul. You can use different things, but directly programming you can use SAX2, XMLReader, and XMLReaderFactory.createXMLReadersee JDK javax.xml package documentation. You could use a DOM object, but I wouldn't recommend it because of memory usage. You can change the underlying XML parser impls for your JDK as well.

data push
Hi All, I would like server A (TC 5.5) to 'push' streams of data to server B (TC 5.5) at random points in time, and for server B to accept the data when it is received. This is not using request / response, hence I am new to this topic. A couple of questions - what protocol(s) can be used, HTTP? How does one push data, than than have it requested? Can anyone point me towards a resource of this nature please? I understand sockets are in the picture - also new to me. Thanks Paul. Paul Wallace BSc Hons.

control Array
Hi,
How might I request a series of checkboxes that all share the
same name? E.g:
form
input type=checkbox name=myCheck value=01
input type=checkbox name=myCheck value=02
input type=checkbox name=myCheck value=03
/form
I understand in VB something called a control array exists, that
retrieves the checked checkbox values and stores them in an array. This
is also possible in CFM. Is there the equivalent in Java/HTTP? Something
where I DON'T have to do:
input type=checkbox name=myCheck1 value=01
input type=checkbox name=myCheck2 value=02
input type=checkbox name=myCheck3 value=03
%
for (int i = 0;i noofCheckboxes; i++) {
myarr[i] = request.getParameter(myCheck + i);
}
%
Thanks for any replies, or direction towards doco re this.
Paul.

OK, Thanks for that. An interesting note however..after some testing, the session is not killed when run from another terminal i.e running the same instance of TC (same server) but from different terminals. That would suggest it is an IE configuration issue (at much annoyance to certain developers). I will at this stage bring this up on the user list!

session expiry
Hello All,
A simple one? I have my session defined in a servlet thus:
HttpSession session = req.getSession();
session.setAttribute(userSession, h); // (h = HashMap)
how or where do define session parameters such as expiry? I would
ideally like my session to die when I call a specified method e.g
close() {
// kill my session here
}
or failing that, how do I define a length of time for the session life?
Thanks
Paul.
oddity
Hello, Can someone please tell me how to configure (I am assuming it is a configuration issue) TC such that my servlets do not insist on persisting. Even when I clear IE history, delete temporary Internet files, cookies, delete the class its self! I literally removed the servlet class and it was still running and outputting to the browser! I eventually had to restart the server each time this happened. Obviously not an acceptable way to develop. Is it an entry in conf/server.xml?

var retrieval from checkbox (with single name)
Hi,
I wish to retrieve / store values of multiple checkboxes checked in the
previous page. The problem here is I dont know how many boxes (a dynamic
amount of them is output), and the checkboxes must have the same name. I
wish to do something similar to Hotmail where I check an amount of
checkboxes, then manipulate the values in the next page. The reason they all
must be name the same - chkboxarray - is to allow a Hotmail style
'check-all', 'uncheck all' facility (below).
The reason for this being that the check boxes checked contain email
recipient ID's (JSP) where I am concatonating email address as a String
value to add to a BCC field. I have tried retrieving and storing in an array
but all I get is the value for the first checkbox.
Any ideas how I can achieve what I'm trying to do while retrieveing the
values with a single checkbox name, or maybe there's someone with a better
solution out there?! Perhaps I need to assign the checkboxes different
names, and edit the JS? (I dont know how to do this)!
Thanks for all input
Paul.
script language= JavaScript
function modify_boxes(to_be_checked,total_boxes){
for ( i=0 ; i total_boxes ; i++ ) {
if (to_be_checked) {
document.forms[0].chkboxarray[i].checked=true;
}
else {
document.forms[0].chkboxarray[i].checked=false;
}
}
}

Tomcat in industry
Hello, I don't know where I heard it, or if indeed I heard it all, but can someone clarify if Tomcat can be used in industrial strength web applications? That is, is it able to handle for example, traffic of 100 hits p/s? Must it be integrated with the Apache web server to make it so? Where may I find such information regarding this please?

ResultSet
Hi,
For the brave, can anyone guess why with this rather unsociable code:
if ((res.getString(3) == null) || (res.getString(3) == )) {
out.println(tda href=takeDetails.jsp?timeSlot= +
res.getString(2) + myDate= + myDate + + res.getString(2) +
/a/td);
}
if ((res.getString(3) != null) || (res.getString(3) != )) {
out.println(td + res.getString(3)+ + res.getString(2) +
/td);
}
the first condition is NEVER satisfied, even though out.println of
res.getString(3) does not display anything! Ie res.getString(3) IS null,
empty or whatever, but the condition is never satisifed. Quickly again, this
is executed:
if ((res.getString(3) != null) || (res.getString(3) != )) {
out.println(td + res.getString(3)+ + res.getString(2) +
/td);
}
even though - out.println(td + res.getString(3)+ - shows it is
empty (no output)!
Thanks
Paul.

cookie retrieval II
Hello Everyone,
Similar to a previous posting, I have some code to make a cookie:
Cookie cook = new Cookie(memberCookie, userid);
cook.setPath(/mydir);
response.addCookie(cook);
and to retreive the cookie:
Cookie cookies[] = request.getCookies();
for(int i = 0; i cookies.length; i++) {
if (cookies[i].getName().equals(memberCookie)); {
out.println(Welcome: + cookies[i].getValue() + p);
}
}
to retrieve the cookie. It retrieves the value but with an additional
nuisance. I get the desired cookie, but also what appears to be the session
ID (output below).
Welcome: paul
Welcome: 61D0D4C3E11302B07308C3D960D13840
I am obviously looping through the length of the cookies array, retrieving
the value, but also this unwanted text. What can I do to retrieve just the
value please? It looks like my if condition is being satisified twice?!
Frustrated
Paul.

cookie retrieval
Hi, a have a JSP page to setup a cookie (Tomcat server):
cook = new Cookie(memberCookie, userid);
cook.setPath(c:/Program Files/jakarta-tomcat-4.0/webapps/mydir/login/);
response.addCookie(cook);
response.sendRedirect(http://myhost/somelocation/mydir/bookings/enterDate.j
sp);
and the page to retrieve the cookie (enterDate.jsp) is:
Cookie cookies[] = request.getCookies();
if(cookies != null) {
for(int i = 0; i cookies.length; i++) {
if (cookies[i].getName().equals(memberCookie));
out.println(Welcome: + cookies[i].getValue());
}
}
Here's the conundrum, if the cookie is retrieved from a page that is in a
DIFFERENT directory that setup the cookie , the output (getValue) returns
only a sessionID ie 8455352001D0C01849A2C480576723D8 and not the required
value. BUT, if the cookie is retrieved from a file in the SAME directory of
setup, the desired output is obtained, plus the same JSESSIONID info. How
may I simply obtain the value of the cookie from any directory, and not the
session ID? I have tried using setPath (above) pointing to the setup and
destination directories with same unwanted session ID output.
Perhaps my syntax of setPath is the problem here? Surely I do not have
to setup and retrieve cookies using files that are in the same directory?
Thanks for all input
Paul.
