Re: problem with msacess

[Ionel Condor]

MSAccess keeps its info in winnt\catroot directory.
Open that database and in options select to show also the system tables.
There is a table which contains accounts.
The mdb is called lcatalog.mdb.

Referrer URL

[Richard Brooks/JHC]

Is it possible to get the url of the referring page, that is, the page
before this one ?  I thought this was possible when I previously used
isapi.

What I am trying to do is to put a 'retry' link on my error page, and more
importantly to log the url of the page that generated the error.

Re: Writing long strings in Oracle

[wayne allison]

Jose,

  If you are getting an exception raised by Java, your
error should be on the Java side of the equation.

  Oracle 8i database "Longs" are up to 2 gig, but you
have to get into the database column.  What does Java
support for a long?  What version of Oracle are you
using?  What are you using on the Java side [front
end]?

  If you are on 8i [I hope], you should investigate
LOB types.

Sincerely,

Wayne Allison

JSP and frames

[Steingoetter, Jochen]

I'm using JSPs within frames and now I'm confronted with a strange behaviour
by IE 5 (seem to work right in Netscape).

In one of the frames my JSP runs a query with the help of a JavaBean and
displays the result in form of a table. The result is
returned in chunks of about 15 rows at a time (determined by a parameter
passed to the bean). The next block of rows is called
by requesting the same page with increased parameter. This works fine and
the page is always generated completely but the
browser seems to still to wait for one item (don't know what item, 'cause
pages looks complete and works fine). With every further
call of this page the number of items the browser seems to wait for is
increased by one.
Same JSP run without frames or in Netscape works without that behaviour.

Does anybody have any idea what causes this behaviour.
Any help is highly appreciated.

Thanks

Jochen

Re: Writing long strings in Oracle

1. do not use LONG, use CLOB instead.
2. look at the examples that come with Oracle for writing CLOBs via JDBC

Re: Writing long strings in Oracle

[Ellis Miller]

You should use a CLOB or BLOB. You should also check out Oracle
technet...there is a very good example of loading LOBs using jdbc. The
complete syntax is there. From the technet site, look for "code samples" or
something like that and you will see a link for using jdbc to load a BLOB
CLOB.

jsp:forward

[Raghavendra i Rao]

Hi,
 I have a jsp that shows a form (User.jsp)and on submitting the form , it goes to 
another page action.jsp. Now if there is any error in the form (which I check in 
action.jsp), I want to transfer control back to the first jsp page (User.jsp. 
Something like a loop ). I use

in action.jsp to do this ,but this does not display the page User.jsp and a blank 
screen is shown with the url showing the page action.jsp.
 Could somebody please let me know how can I get this accomplished.

In User.jsp I have :
document.rfUserMgmtform.action ="action.jsp";

In action.jsp I have


 It is some kind of a loop behavior. I am using jsp forward since I need to forward 
the request parameters from action.jsp to User.jsp .Any help is highly appreciated.

Thanks in advance.

Re: Proprtionate String Padding

Thanks a lot Santosh, Naresh & Richard for your invaluble input.

"Strings are constant; their values cannot be changed after they are

If a string is constant, I should not be able to change its value after it's

This should work, assuming you're using a JSP 1.0/1.1 container (as opposed to a
0.9x
container). If you are using 1.0/1.1, it sounds like a bug in the JSP container.
Which one is it?

Request parms need to be stored in the  session and retreived for next

also make sure both the jsp are in same path.

Re: [Re: Proprtionate String Padding]

[abhishek shodhan]

Java Strings are not advisable as far as possible as each new String Object
will need to be Created in the Memory, and hence will slow down the
Application/Page. and considering that we are programming on the web, we might
assume that we would get a lot of Hits on the JSP page. That will create even
more Threads of Code, and hence even more String Objects.

String Buffers, on the other hand are easier to manage and Easier on the
Server.

Why do you need to Pad the String anyway? Just thinking... why not Trim it?
(String.trim())

Love Always,
Abhishek Shodhan.

Re: Proprtionate String Padding

[Richard Yee]

Using a StringBuffer is more efficient than using a String because a
StringBuffer can be appended to.  If a String is used, all of the contents
in the String must be copied each time it is created.  With a StringBuffer,
you re-use the same object as you append to it.  When using a String, you
are creating (and destroying) String objects each time you do an append.
With a StringBuffer, you can also easily do a string insertion.

Moreover, a StringBuffer is used for doing the concatenation of two String.
So better save sometime and use the StringBuffer from the beginning.

Scanner

[Philip Moschovas]

Hi, I'm doing a web project using a hand held scanner that reads barcodes.
I don't have the scanner yet and I was wondering if anyone has any
experience with one of these.  I need to know what sort of event is
triggered when the barcode is scanned into a textbox.  I need to get a jump
on this project and i'd like to know before hand if possible what event to
code for.

Thanks,
Philip Moschovas

Tomcat and Date

[krishna Patel]

i am using tomcat, sqlserver 7.0, servlets
it messes up date time

Re: Scanner

[Hu Jeff]

As far as I know, a barcode scann reads an image and stores the string (The
string is what that image represents). I think you have to download the
barcode info to your computer first.

Re: Scanner

[Gutman, Larry]

I believe it just fills in the text just as if you were typing it in.  At
least that is my experience.  There is no special action that is done.

I try the hand-held scanner b4, it just like a keyboard but it will

JSP + Servlets and getLastModified()

[Stuart Maclean]

In the HTTPServlet world, the servlet container gives my servlet the
chance build a response based around the '304 Not Modified' message,
via a long valued integer specifying a last modified time
(getLastModified()).  Great stuff, invaluable for servlets which
format some data once and then serve it forever.

Hmm, now I'm into JSP,  if I have a JSP page with static HTML and a
single  of a servlet, there seems no way for the JSP page
implementation class to handle this notion of lastModified().

Hmm, the HttpJspPage doesn't even extend HttpServlet so I guess this
functionality isn't planned?

I have perused the JSP 1.1 spec, nothing.

I'm tempted to wrap all my JSP pages inside servlets, using
requestDispatcher.includes()s, so I'll get the 304 options back...

Anyone any comments?

Re: Scanner

[Arun Thomas]

Most barcode scans also tend to be number oriented - there are coding
schemes
that allow letters, but the basic translation is into a number.  Your
scanner
will probably be responsible for transforming the barcode into an
(alpha)numeric
string, which will be the value inserted in the web form field by the
scanner.
The event triggered should be no different that when a value is typed into
the
textbox.

Re: Error in catching Param Variables

[John Luk]

You  should also check for nulls on the request.getParameter.  If you are passing
in null values it will give you the error.

Re: Compilation

[B R Nair]

Dear Manish,
Thanks for your input. I changed your first command a little bit because the
first command that you gave me (javac -J-Djavac.pipe.output=true
*.java>error.txt) was not working.

Sorry for disturbing you. Your revised command
javac -J-Djavac.pipe.output=true Hello.java>error.txt
runs but it always gives an empty error.txt, eventhough errors are reported
on the screen. Is it a bug in 1.3 candidate version? I am still using 1.3
candidate version!

Thanks and regards
BRN.

JSP and ASP

[V.Vasant]

hi,
Can someone point out to me how does jsp perform better than
asp.I am a newcomer to jsp even though I've worked with java for quite
some time.Apart from the portability issue , I don't find something
convincing in using jsp than learning asp. Please help.

Re: JSP and ASP

[Alex Amies]

1. COM components referenced from ASP's hang the web server and
   possibly the system if they have fatal errors.
2. COM components made from VB are not thread safe.
3. Programming COM components in C++ involves some hairy ATL
   programming with multiple inheritance and template classes.
4. The VB script language used to program ASP's has serious
   limitations including no notion of variable scope.
5. You cannot have custom tags in ASP's.  It will be difficult
   to make them into XML documents in order to manipulate content
   in other tools.

Despite these limitations ASP's are the easiest way for new
programmers to author web pages that create dynamic content from
a SQL database.  Thus the popularity of ASP pages.

Nested JavaBeans

[Drake Pyrosius]

Hello all,

Does anyone have any recommendations on handling nested JavaBeans in a JSP?
For example:

public class Address
{
private String firstLine, secondLine;
private String city, state, zip;

set/get() ...
}

public class Person
{
private String name;

getName/setName() ...
}

And in the JSP:



The tag  will only return Strings and as such getting to
the nested Address object's individual properties is difficult.

Attempting the following on Tomcat fails:


<%! Address address = person.getAddress(); %>


Apparently in the generated source another instance of Address is
initialized which hides the one that is manually declared.

Another attempted workaround also fails:


<% address = person.getAddress(); %>


Similar problems crop up in the generated source as the first hack.

I seem to recall a NESTED modifier to the bean tag in 0.92 though I don't
recall it's use and can find no mention of it in 1.1.

I see two alternatives, but I hope someone can suggest better ways:

1) Having the forwarding servlet (model 2) place the nested bean in the
Request object along with the enclosing bean. e.g.
req.setAttribute("person", personObj);
req.setAttribute("address", personObj.getAddress());
This doesn't make much sense considering person contains an
address. They don't belong on the same level structure-wise and just from an
intuitive standpoint one should be able to navigate down the tree of
JavaBean properties.

2) Create a custom tag along the lines of

This seems an extraordinary and non-standard thing to do. It's bad enough
that iteration tags have to be implemented in a proprietary fashion.

In any case, if anyone has any suggestions I would be appreciative.

Thanks,
Anthony Yu

Not true. Web Development with JavaServer Pages, by Fields & Kolb (perhaps

Dear Manish,
Thanks for your input. I changed your first command a little bit because the
first command that you gave me (javac -J-Djavac.pipe.output=true
*.java>error.txt) was not working.

Sorry for disturbing you. Your revised command
javac -J-Djavac.pipe.output=true Hello.java>error.txt
runs but it always gives an empty error.txt, eventhough errors are reported
on the screen. Is it a bug in 1.3 candidate version? I am still using 1.3
candidate version!

Thanks and regards
BRN.

Re: JSP + Servlets and getLastModified()

[Oleg V Alexeev]

Try to use one of listed below methods:
1. Insert code to JSP
 <% response.reset();
response.sendError(SC_NOT_MODIFIED);
   %>
2. Write any tag implementation as
 class TestMidifiedTag extends TagSupport {
  ...

  public int doStartTag() throws JspException {
   HttpServletResponse resp = (HttpServletResponse)pageContext.getResponse();

   if() {
resp.reset();
resp.sendError(SC_NOT_MODIFIED);
   }
   return SKIP_BODY
  }

  ...
 }

 and use it in JSP as

 

 with all needed actions for tag library registration and tag definitions
 for it.

SM> In the HTTPServlet world, the servlet container gives my servlet the
SM> chance build a response based around the '304 Not Modified' message,
SM> via a long valued integer specifying a last modified time
SM> (getLastModified()).  Great stuff, invaluable for servlets which
SM> format some data once and then serve it forever.

SM> Hmm, now I'm into JSP,  if I have a JSP page with static HTML and a

SM> Hmm, the HttpJspPage doesn't even extend HttpServlet so I guess this

SM> I have perused the JSP 1.1 spec, nothing.

SM> I'm tempted to wrap all my JSP pages inside servlets, using

It's not beautiful, but this should work:

  <%@ page import="Person, Address" %>

  
  <%
Address address = person.getAddress();
pageContext.setAttribute("address", address);
  %>
  

Two things differ from your example:

1) I use a JSP scriptlet as opposed to a JSP declaration to retrieve
   the Address bean from the Person bean. JSP declarations end up
   outside the _jspService() method in the generated servlets, so
   variables declared in a declaration become instance variables
   instead of local variables.

2) I add the Address bean to the page scope, by calling setAttribute()
   on the pageContext object. The  and 
   actions (as well as custom actions) can only get access to objects
   available in one of the JSP scopes; they don't have access to
   scripting variables.

I also added a page directive to import the Person and Address classes,
since classes that do not belong to a package are not automcatically
visible in a class that does belong to a package (such as the generated
servlet class in most JSP containers).

Passing Query String with URL

[B.V.Murali Krishna]

hi all,
   I am using a javascript function in Jsp, where i am calling another Jsp
and passing a query string with it. The problem is that the query string
paramater values which are javascript variables are not converted to their
values.

onclick="go_to(user.value,pwd.value)">
function go_to(u,p) {
 alert(u);
 alert(p);

document.location.href="http://localhost:8181/LoginCRMPrj/Change_Pwd.jsp?use
r=u&pwd=p"
 }

The values are user is retrieving as u and not the values same for pwd.

Can someone please help me.

Thank in advance,

The beans use properties files - which are also stored in the servlet
directory.  When I make changes to the properties files Websphere seems the
reload the Servlets! Is there a way to stop Websphere reloading Servlets
when I change properties files??

Note JSP pages instantiate and call the beans.

Regards

Marc

Writing long strings in Oracle

[José Antonio Quiles]

Hello,
we are trying to insert a huge string in an Oracle LONG field via JDBC; we
are using PreparedStatement.setString().
However, when the string length is longer than 2000 characters, a JDBC
exception is raised.
We thought that Oracle LONG field supports any string length...
What is the problem?

Thank you in advance,

Re: Writing long strings in Oracle

[Lakshminarayanan.A, AMB Chennai.]

Hi,

If you insert your string values thru' SQL query the maximum
allowable string size is 4000 chars( Oracle 8.x).

Solution :
Use oracle bind variables.(please refer Oracle documentation )


ORA-01704 string literal too long

Cause: The string literal is longer than 4000 characters.

Action: Use a string literal of at most 4000 characters. Longer values may
only be entered using bind variables.



hope this helps

JSP & DB2

[Ionel Condor]

Hi,
If someone uses IBM DB2 as his DBMS for JSP here is a question:

I have two databases, each with a few tables.
Somewhere in a bean I write a query which must use a table from DB1
and a table from DB2 is a select statement.
Does anyone know how to configure DB2 (grant statements I suppose) in
order to succeed... I mean one of the DB to see also the tables from the
other DB.

I have done the same thing in Oracle by allowing rights on a scheme
but I don't know how can be done in DB2. Please give me an example.

Thanks,
Ionel Condor.

Re: Accessing (only) form parameters.

[SANDIPAN DUTTA]

I have tried all that.

But the problem is that I have to get (ALL) the form parameters only and
store it. If I do request.getParameterNames and then try to loop through
it, it gives me stuff like query-strings, HTTP headers like Host ,
gx_session_id etc.

I need something like request.getParameterNames("formname")

Any pointers here would be greatly appreciated.

Thanks
Sandipan.

Re: How to refresh a JSP-Page

[TODD HARNEY]

Yes, I forgot to mention that I do have a Boolean stored in the session variable that 
is false initially and then set to true before I send the refresh meta tag...I then 
remove it that next time through. Yes, if you just send this meta tag as is, it will 
loop endlessly...sorry about that.

Todd

>>> [EMAIL PROTECTED] 7/27/00 5:48 >>>
Just like to point out..doing it on a JSP page might cause an endless loop.
As it refreshes, it sees the header again and again each refresh. If you do
want to do this, I suggest putting a counter variable in the http session
and only refresh if it doesn't exist. The second time around it would see
the var is there and NOT return the  tag, but remove the session var
as well.

Re: Accessing (only) form parameters.

[TODD HARNEY]

You could employ a naming convention for your form parameters such that if you have a 
form named "myForm" and a field named "userName", you could change the field name (ion 
this example) to "myForm.userName", then call request.getParameterNames() and in your 
form loop, filter for names beginning with your form name. You could also make the 
form name a property in a property file so that it is not hardcoded in your JSP 
source. Just a thought.

Todd

Connection to a database - failure

Hi all,

Can somebody please help me with this problem.
When I compile this source-code, for making a connection to a database,
I'll receive the error "type expected" in the first TRY-statement.
How can I solve this and what does it mean?
Thanks,
Marcel van Kooy

import java.sql.*;

public class TestBean {

try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}

catch( Exception e ) {
System.out.println("Failed to load JdbcOdbcDriver.");
return;
}

try {
Connection con =
DriverManager.getConnection("jdbc:odbc:Studio_Bezoekers", "", "");
Statement select = con.createStatement();
ResultSet result = select.executeQuery
("...A query...");

Hey, but notepad is quick and easy. What more do you *want?* An editor
that doesn't load or save, but runs slowly? (Sounds like a Java editor to
me *run*)

Re: Connection to a database - failure

[TODD HARNEY]

The code needs to be inside of a method...you have no method defined.

Re: Connection to a database - failure

[Kumail Rizvi]

Hi
  I think u r using JDBC-ODBC bridge.
If it is, its mean Studio_Bezoekers is ur DSN.

now it depends on what data base u r using
if Oracle then define user name and password in DSN and is Access then no
need for User
name and Password.
just use

DriverManager.getConnection("jdbc:odbc:Studio_Bezoekers");

this will run fine


Best Regards

Kumail Rizvi

Re: problem with database

[Oren Klichevsky]

what do you mean by that ?
passwords are a way to keep your information secured, so if someone defined
a password for the database, you need to use the regular user name +
password security system of the database.
you should ask for the password or define a new DB user that will be granted
the rights to access the desired tables.

Re: JSP editor

[Geert Van Damme]

The time you win in faster loading, you lose in lack of features that make
life easier.
Don't compare it with the big dinosaur IDE's. They can be very annoying at
times (e.g. during startup), but there are a lot of good editors that fall
in between.
