LOC counter

[Karau, Joe]

One of my managers was recently asking about the size of our project.

So, I started looking around on the web and I could not find a good LOC
counter.

Does anyone know of a tool (freeware preferable) that will count the lines
of code for java source and JSP's, or even one for each.
Thanks.

Re: Word API

[Karau, Joe]

There is support for reading and writing microsoft formatted documents (.doc
and .xsl for sure) on the jakarta web-site.  Don't recall the names of the
api's right now (POI?). I haven't started using them yet, but from what I
read about them I am planning on using the .xsl one api in a similar manner.

Hope that helps.

Subject: Word API


Just to see if there is anyway to do this.  I am needing to create an
application that will display a Microsoft Word document that has fields
defined in it.  Then the user can modify these fields, and then save these
fields back to a database.  I know you can do this using Active X and such,
but can I do this anyway in JSP/Java?

Re: File not found???

[Karau, Joe]

Not sure if a type or not, but you are using two different file names.

myfile01.txt and file01.txt.

May want to double-check that.

CL,
You need to use the getRealPath() method in the ServletContext class in
order to get the path to the file in your web application.

String myPath =
getServletConfig().getServletContext().getRealPath(/WEB-INF/files/myfile01.
txt);
br = new BufferedReader(new FileReader(path));

In order to check to see if your path string is correct, you should check
and make sure myPath is not null. If it is null, then the path is incorrect.

This problem can also be found in the archives of the servlet-interest
mailing list.

Not sure how you would do it to a JSP.  However, you could open a URL
connection to a servlet and send the serializable object to the servlet.

HttpServletRequest characterEncoding

[Karau, Joe]

Hi,
I'm working on internationalizing our site.  So far, every thing is
coming from the server in UTF-8 fine.  However, when a user sends a request
to our server, the HttpServletRequest.getCharaceterEncoding method is
returning the encoding of iso-8859-1.  I've found that in the newer
Servlet spec, I still have to use 2.2, there is a method for setting the
character encoding on the request object, but I have not found any way of
doing it in 2.2.

Any help, tips, or ideas would be greatly appreciated.  Thanks.

Yes, this is a problem caused by browsers not complying with the
HTTP spec. Most of them don't send a Content-Type request header
with the charset used for encoding the parameters.

 Servlet spec, I still have to use 2.2, there is a method for setting the

In 2.2 you have to do the conversion yourself, like this:

   String requestCharset = UTF-8;
   String encodedValue = request.getParameter(myParam);
   String decodedValue =
 new String(encodedValue.getBytes(8859_1), requestCharset);

Re: Column index out of range ???

[Karau, Joe]

try using the query:

select distinct(user) as user from pcinfo order by user

... just using select disinct user as user from pcinfo order by user
is most likely returning a column named distinct user  I'm not sure if
that is part of the SQL standard or not, however it is very common among
relational databases.

Re: Column index out of range ???

Yes, sorry about previous comment, didn't look closely enough at the code.
You'd have to do what I suggested if you were retrieving the column by name
instead of by position.

That's because you're asking for column 2.  When you use the *, it's
returning enough columns.  When you only ask for User, you have to change

 What's the code for where you build your SQL, retrieve the columns after
 executing the query, and the table definition(s) for the table(s) that
you
 are querying?

Most probably there is a type somewhere between you form's fields, and the
name of the parameters you are trying to retrieve.

Re: change html form elements within a %@ include file fileex.ht ml

[Karau, Joe]

input type=text name=[element_name] value=

where

* is either %=request.getParameter([some_parm_value_name])%
or
%= (String)request.getAttribte([some_att_value_name])%

or

%= [some_string_object] %

otherwise, if it must be done dynamically, you can use javascript...

script language=JavaScript

document.[form_name].[element_name].value = [value to set to];
/script

hope one of these is what you need.

Re: change html form elements within a %@ include file fileex.ht ml

[Karau, Joe]

Please ignore the majority of my previous reply, did not read the message
close enough. sorry.

The best method would be to use the javascript, unless you want to change
the html into a jsp and do a
jsp:incude page=/altera_senha_colegio.jsp /

instead of doing the include file directive.

Re: Connection pooling problem

[Karau, Joe]

Yes, you should wrap it in a try catch finally construct.  And return the
connection in the finally.  That way, you are GUARANTEED (as long as the
server is not killed in the middle of the code) that the connection will be
returned.

It would be possible to allow the error page to return it, but then you'd
have to place the connection in the session, get it out on the error page,
and return it.  Possible, but not good coding practice.

Subject: Connection pooling problem


Hi gurus, this is the typical layout of my page:

%@ page ... errorPage=error.jsp %
...
%

SQLManager myMan = SQLManager.getInstance();
Connection myConn = myMan.requestConnection();

...
...
...

myMan.returnConnection(myConn);
%

Now, if an exception occurs after requesting a connection to the pool and
before releasing it, that connection is open and is not gonna be closed till
PoolMan timeout. In a production environment with an average of 100 active
sessions this cannot be acceptable. If a page has errors in it after a
product release, all the connection objects in the pool are gonna be open
and unusable in seconds.

Now my question: how can I handle this? Do I need to put everything in
try/catch blocks? Is there any way to pass parameters to the error page?
Thanks. Cheers, Vittorio

Re: SCROLLABLE TABLE IN JSP

[Karau, Joe]

We've run into the same problem.  What we did to solve was use an iframe
to hold the table contents and put the headers on top.  This did however,
cause the header column widths, and table column widths to be slightly
mismatched though.  Definitely not the most elegant solutions, but it did
work.

(If you run across anything better, would appreciate it if you'd let me
know)

Just get your data, build the two dimensional array per method spec, and

Re: Urgent help needed

[Karau, Joe]

I'm not sure if it is the same problem but...

We use VA Java as a development IDE, and in the past we had a problem where
a class that we exported from VA Java could not be loaded by any other JVM.
After working with IBM we found that it is because VA Java had a bug and it
was exporting a java class with invalid byte codes.  The error we'd recieve
when trying to load this class was very similar to what you are getting.
I'd try writing a small test stub that uses the class loaded to load the
class, and test on a couple of different JVM's.  The class file that you
have may be corrupt.  If it fails to load in other JVM's as well, you'll
have to contact the authors of the class and see what can be done.

Hope this helps.

Subject: apache + tomcat ??


 Hi,
 I installed Apache to work with tomcat, if I wok from tomcat directly:
 when I type http://mil2wwds10:8080/jetspeed/
 I got http://mil2wwds10:8080/jetspeed/index.jsp
 and everything works fine.

 But if I call from Apache port :
 http://mil2wwds10:80/jetspeed/
 I got only a page that show all the files and directories under jetspeed,
 then I have to click in index.jsp to be shown, and when I click in a link
in
 the index.jsp file, if the link is an html file it works fine, but if it's
a
 jsp or servlet it does not work.

If you try to use Swing in an applet, it is going to require the browser to

Re: Jsp and Swing??

[Karau, Joe]

tried what exactly, you really need to be more specific.  If you are talking
about using Swing components to create the GUI for the client...
You can, but shouldn't unless you have a small number of users that will be
using your app, and/or until browsers start shipping with a Java2 JVM.  The
JVM's that currently ship with browsers do not have Swing components
available, so users will have to download a plug-in that allows Java2 code
to be run in applets.  Possible, but not adviseable for apps where you have
no control over who is going to be using it.

As far as using Swing components for the GUI.  It can be done, but only as
an applet, which is why I mention the browser's JVM above.

If you were asking if Swing components could be used in the Java Scriptlets
of your JSP page.  Of course they can, you can write just about any Java
code in the Java Scriptlets of JSP pages, because when everything is said
and done, they are basically transformed into little itty bitty prorams.
However, when a user calls the JSP page using the Swing components the Swing
GUI will appear on the SERVER machine, not the client.  This will not only
happen the first time that the page is called, but EVERY time the page is
called.  Meaning that if the page that contains the Swing components is
falled 100 times, you will have 100 Swing windows open on your server
machine.  Which in turn will gobble up the resources like a mad man.

So, my advice is do not use Swing components in JSP unless you understand
the implications.

Re: deploy issue

[Karau, Joe]

not only does it use the last change date of the jsp file to see if it must
recompile the page.  But the majority of servlet/JSP engines actually use
the file to get the static text.  In other words, anything that is not
enclosed in JSP tags or scriptlets is read from the file when the jsp is
called by the server.  So, the chances that you will be able to distribute
JUST the class files is almost 0.  If you must just distribute class files,
and not the JSP source itself, you'll probably have to do something evil
like implement the entire app as servlets.

JRun stores the class files for JSPs in
servers/yourserver/yourapp/Web-Inf/jsp.
However, I believe that the 1.1 specification requires that the container
check the
actual *.jsp file to see if it has been modified since the last *.jsp to
*.class
translation and compilation. This means that the *.jsp file must exist.

If there is a work around I would love to hear about it. I'll look forward

 I don't want to give the JSP code to the clients, as i am building this

 So, how can the things be resolved. If in place i would have used =3D

 Is there some tool so that we can convert .jsp into class file for once.

 Pls let me know how to get out of this situation.

 I am using IIS, and JRun for it.

Re: Jsp and Swing??

[Karau, Joe]

By the nature of JSP and Swing, you can not really use them together.
Technically you can of course, except any swing components created in the
JSP will appear on the server, but if multiple requests are made to the same
JSP multiple windows will open.  (not the greatest idea)  If you want the
client to see Swing components, you have to write an applet that uses them,
but you should note that the user will have to download a plug-in from sun
in order to display an applet that uses Swng components. This can be done,
but is usually not an optimal solution, depending upon how many users will
be using the applet.  You don't want hundreds of people to have to download
a separate plug-in in order to access functionality of your site.

Re: Printing problem in JSP

[Karau, Joe]

well, if you are talking about the output of the jsp (which I'm assuming you
are) not really.  Most browsers will print as much of the page as they can,
and then truncate the rest (speaking about width of course).  The best you
can do is try to design the page so that it will fit onto one page when
printed.

Re: jdbc taglib question ?????

[Karau, Joe]

you'll probably want to put the %= request.getParameter(name) % in single
quotes, and use wild card characters.

example:
select * from [table name] where [column name] like '%=
request.getParameter(name)%[rdbms wild card]'

this would find any results where the column name had a value that started
with the parameter, it will be able to make use
of an index, if one is built on the column name.  However, if you would like
to find records where the parameter
is found anywhere within the value of the column name put the wild card
before the parameter as well.  (index won't be used though)

Re: Hidden field NULL values after POST

[Karau, Joe]

If you are setting the value of pSHIP with javascript, I've seen the same
type of problem.  To fix I gave an initial value to pSHIP of an empty
string, such as:
input type="hidden" name="pSHIP" value=""

That seemed to fix it for me.  Hope this helps.

Subject: Hidden field NULL values after POST


I have encountered a very strange issue with JSP when I submit a form with
hidden field.
The value of the hidden field is displayed as null when I do a
request.getParameter("pSHIP") after submitting the form for the first time.

But when I click on Back (on the browser) to go back and submit the form
again, the value is correctly displayed!

1. I have a Form with input type="hidden" name="pSHIP"
2. When I submit the form I set pSHIP.value to "OCEAN2001"
3. JSP displays value of pSHIP as null
4. Go back  submit the form again
5. JSP displays value of pSHIP as "OCEAN2001"

Anyone has any ideas why this happens? I'm working from JDeveloper 3.1.

Regards
Willy

 Do a google search, any search. Do a "View Page Source",
or just move your mouse across the page number links.
Look at the format of the URLs: that's how the client side
works. How the server side works depends on your
application. If you're trying to page around through
database results, there's been some dicusssion over in
servlet-interest. Try searching the archives[1] with terms

Re: PRINT UTILITY PROGRAM

[Karau, Joe]

A print module would have to be a java applet, and I believe (but I very
well may be mistaken) that it would not be able to get the entire graphics
context of the page that the applet is embedded in.  Even if it could, in
order to use the printer the applet would have to be a signed applet, not
really an issue bet something that should be noted.

It may be much more time efficient, though not as elegant as what you are
envisioning, to simply use javascript to bring up the browser's print dialog
when the user presses the print button.

Re: login servlet ??

[Karau, Joe]

Sufi, you could encode the url of the servlet, and pass the url of the
servletA as a parameter.
Example href=/servlets/YourLoginServlet?ToServlet=SerlvetA

Then, in your login servlet simply do a
String forwardTo = request.getParameter("ToServlet");

and the "forwardTo" String will be the url of the servlet that you
originally linked to.

To be on the safe side though, you may wish to encode the URL of servletA
using:

href=/servlets/YourLoginServlet?ToServlet=%=java.net.URLEncoder.encode(stri
ng_of_servletA_url)%

Re: sendRedirect ??

[Karau, Joe]

because response.sendRedirect takes a string, look, copied straight from the
documentatation:

sendRedirect
public void sendRedirect(java.lang.String location)
  throws java.io.IOException

Sends a temporary redirect response to the client using the specified
redirect location URL. This method can accept relative URLs; the servlet
container will convert the relative URL to an absolute URL before sending
the response to the client.
If the response has already been committed, this method throws an
IllegalStateException. After using this method, the response should be
considered to be committed and should not be written to.

Parameters:
location - the redirect location URL
Throws:
java.io.IOException - If an input or output exception occurs
java.lang.IllegalStateException - If the response was committed

Joseph Ottinger

[Karau, Joe]

I agree with Joseph as well.  There are way to many subscribers to this list
asking either off-topic, or "simple" questions.  They are, in my opinion,
being quite lazy.

Those asking off-topic questions should probably try to find the appropriate
forum for their questions, they would probably get more responses, and those
that they received would also probably be better.

Those asking the "simple" questions, the questions themselves may not really
be simple, but if they would try to spend time searching for the appropriate
reference and answering it themselves they will learn much more than if
somebody else just answers the question for them.

Mailing lists such as this are an excellent way for programmers to probe the
knowledge and experience of other programmers who have experienced similar
problems.  However, by simply answering all of these off-topic posts, and
"simple" questions without at least suggesting that they find the right
place to ask them, or spend some time trying to figure it out themselves,
will only increase the frequency that such questions are posted.  Thus,
bringing down the usefulness of the list.

As far as the personal attacks on Joseph whenever he posts a reply that may
be less than utterly polite, why?  OK, his replies may seem very abrupt,
sometimes condescending, and a little less than professional.  However, is
it professional to go ask your secretary how to execute a simple SQL
statement, no because she would be the wrong person to ask and that is
fundamentally what the people that are posting off-topic questions are
doing, asking the wrong person.  So, if you don't like his relies, don't
read them, but there is no need to constantly flame him.

By the way Joseph, I'd be more than interested in joining a JSP list that
focuses more on JSP.

Re: How jsp applet communicate ???

[Karau, Joe]

Sufi, a JSP file is a source file that contains bits of JAVA code, and HTML.
When the user requests a JSP file, it is first parsed into a regular *.java
source file, then compiled into a *.class file (which by the way is a
servlet), and finally the servlet executes providing the user's browser with
HTML. (overly simplified, but basically correct)

An applet is basically a JAVA application that runs within the browser
instance, you declare the name of it, and any PARAMETERS that you want to
pass it in the HTML.  View your favorite HTML reference for details.

Therefore, unless you are going to do some special work to allow the applet
to communicate with a servlet (have not been able to get it to work with a
JSP).  You have to pass the parameters to the applet based on output from
your JSP.

Yes, but I am sure there is a way that you can pass a parameter from

remember where.

Sufi, a JSP file is a source file that contains bits of JAVA code, and
HTML.
When the user requests a JSP file, it is first parsed into a regular *.java
source file, then compiled into a *.class file (which by the way is a
servlet), and finally the servlet executes providing the user's browser
with
HTML. (overly simplified, but basically correct)

An applet is basically a JAVA application that runs within the browser
instance, you declare the name of it, and any PARAMETERS that you want to
pass it in the HTML.  View your favorite HTML reference for details.

Therefore, unless you are going to do some special work to allow the applet
to communicate with a servlet (have not been able to get it to work with a
JSP).  You have to pass the parameters to the applet based on output from
your JSP.

Re: Can't convert int to boolean. ??

[Karau, Joe]

you also want to user == (which is the comparison operator) instead of =
(which is the assignment operator).  Two suggestions for you.
1. Spend a little more time reviewing syntax (and all other options) before
asking for help.
2. To prevent problems similar to this in the future do null == whatever,
therefore when you forget one of the equal signs and code this null =
whatever, it will help you to realize that you missed an equal sign because
you can not assign anything to null.

OFFTOPIC - Problem with HTTPServletResponse.sendRedirect(String) on only one environment

[Karau, Joe]

Hi, this is both on and off topic, but more off topic than on I feel.
Here is the situation:
We have a JSP in the root directory that allows a user to enter
their username and password, and this JSP posts to a servlet to do the
processing.  When the servlet completes the processing is does a
response.sendRedirect to an HTML page.  This HTML page is nothing but a
frameset that references a head.html, and two JSPs that are also in the root
directory of our server.

Environments:
It works fine in our development machines VAJava 3.02, and AS/400
v4r5 running WebSphere 2.0.
It works fine on our production machine, running AS/400 v4r4 and
WebSphere 2.0.
It is failing (only for our subscribers) on our disaster recovery
machine that is also running AS/400 v4r4 and WebSphere 2.0.
The HTTP configuration, and our application are identical on our
production machine, and disaster recovery machine.

Problem:
While attempting to test our disaster recovery machine, we found
that our subscribers are getting 404's for all the frames in our home
frameset.
It appears that after they log on that the servlet does the send
redirect, they are requesting the header, and JSPs that make up the frameset
from, the root/servlet/
directory, not the root directory as they should be.  Also, after the
servlet does the sendRedirect the url or our logon servlet is being
displayed in the client's URL field of their browser, however this does not
happen in any of our other environments AND it does not happen when we try
to access the application from within our own intranet.

Maybe I'm mistaken, but from what I've been able to tell from the API specs,
is the behavior the client is seeing on our disaster recover machine is
closer to the behavior that should be expected from a request.forward(), not
a response.sendRedirect().  I was under the assumption that a
response.sendRedirect() would cause the client's browser to behave as if the
user themselves had typed the URL in their browser, whereas a forward would
simply leave the browser url that of the page/servlet doing the forward,
even though the HTML that would be displayed would be that of the page that
was forwarded to.

Any comments, ideas, or other resources to look at would be greatly
appreciated.

Re: Diff bet asp jsp

[Karau, Joe]

A JSP is only compiled, and thus parsed, when the source JSP is newer than
the compiled java source, and class file it generates.  When this parsing is
completed, a JAVA source file is created, following which a JAVA class file
is compiled based on the generated source.

Even if the content is changing, like in a forum to use your example, the
JSP will not have to be recompiled. Unless, the author has actually coded
the JSP to change its own source code as more messages are added, doubtful.
No, instead the messages are stored through some other type of persistence
mechanism, most probably a database.  Thus, when the page is served to the
user the servlet (which is the compiled version of the JSP) queries the
database, and uses the query to generate the HTML, which is then sent to the
client.

Handling the browser going back

[Karau, Joe]

I understand that disabling the "Back" feature of a browser (whether the
user uses the back button, right click - back, etc) is not really a valid
option in most web-applications.  However, we are having problems with the
user choosing to go back to previous pages, and I was wondering how others
are handling this.

Any ideas, advice, or sources to check would greatly be appreciated, thanks.

Re: How to access JSP variable from javascript?

[Karau, Joe]

You can not access JSP variables directly using javascript because of the
most basic difference between the two.  JSP is a server-side scripting
language.  The JSP engine builds source code for a servlet from the JSP
page, the servlet is executed and html is sent to the browser.  Whereas,
javascript is a scripting language that the client's browser interprets and
executes.  Thus, it is not possible to DIRECTLY access JSP variables.
However, you can use JSP to place String variables within javascript so that
the javscript can be created dynamically.

For example, the following code:

% String some_jsp_var = "This is a java variable instantiated in a
JSP."; %

script language="Javascript"
function callMessage(){
alert("%=some_jsp_var%");
}
/script

would produce the following html to be received by the client:

script language="JavaScript"
function callMessage(){
alert("This is a java variable instantiated in a JSP.");
}
/script

In short Ganesh, you can use the values of JSP String variables within
javascript, however remember that there is no way to change the value of JSP
variables from javascript because of the environments that each language
runs on.

Re: Stored Procedures

[Karau, Joe]

Stored procedures will be more efficient then using JDBC and directly
running queries.  However, the difference may not be noticed unless a large
and complex query was performed.  The reason that stored procedures are more
efficient, is that they are stored in the database as optimized queries.
Therefore, they do not need to go through the SQL optimizer, and often no
longer need to go through the SQL parser.

If using regular SQL however, the query will have to go through the SQL
parser, and the query optimizer before it is run.  Thus, taking more time
than stored procedures.  As I mentioned earlier, if the query is simple
there will be no noticeable difference.

Subject: Re: Stored Procedures


I'm just tryin the best solution between simple queries and Stored
Procedures.

So i placed 5 tables, integrally referenced each other, and the main table
has 100.000 records.

I tried a query that joins these tables and a stored procedure that does the
same thing.

The result was the same: 4 seconds to execute both the query and the stored
procedure. So we decided to use queries... there are less troubles in
deploying the application.

Hope this can help you...

Re: Urgent ! about downloading of GIF

[Karau, Joe]

You could use an applet, however I wouldn't.  If you are worried about the
time it takes a gif to download, than you should be more worried about the
time it would take to download the applet with the gifs.  With the applet it
will be done all at once, making it appear to the user that it takes
forever.  With the gif/page, at least the total download time will be split
across multiple pages.

Subject: Urgent ! about downloading of GIF


hi
my prob. is  that , every page in our site has got a gif image.
since we hve a number of gif's , it takes time to download. each page
has got a diff. gif images.
is there any possibility that if i use applets
(which will be stored in the RAM of client) to do this.
so for each page , i can use the Applet to show the picture
rather than downloading from the Server.

can anyone suggest me how to do this?


Thanks in advance

Re: Blank lines on JSP

[Karau, Joe]

Yes, the blank lines will increase the size of the documnt, but only by one
or two characters per blank line.  However, I believe those lines are
inevitable because they are placed there by the JSP processor.

blank lines will increase the size of your document (hence download
time:-), so
ideally you should always try to remove all these white characters.

 Hi all,
  I have an issue regarding JSPs.
  Most of my JSPs have many directive statements (jsp tags) at the
beginning
 of the file,
 and because which, the contents (html )are displayed  after a few blank
 lines !

 any idea to rectify it ??

 I have tried putting some html tags at the top of the jsp file , then
added
 the directives after them. but still the same result :(

 Thankx

Re: Ending line of code with ;

[Karau, Joe]

because what %= someVariable % is actually doing is:
% out.println(somVariable); %
therefore all you are doing is passing the argument for the out.println
method

Re: Order of parameters

[Karau, Joe]

Make sure the parameters are named, and then use a
request.getParameter(parmName) to get the value of the parameter.

Ex.
input type=hidden name=Parm1 value="Value1"

then, when processing the post/get do
String parm1 = request.getParameter("Parm1");

and parm1 will be equal to "Value1".

You will then be able to manipulate the values as you see fit.

Re: How to write functions and procedures in JSP?

[Karau, Joe]

Because of the system.out's you're probably outputing the data in the inner
functions to the web-server, instead of to the response's out stream.
