Connection pooling problem

[Marino Vittorio]

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: Need your help on request.getParameter and Chinese encoding.

[Panayotou, Michael]

You have to translate the parameter from one character set to another. for
example :

String myparam = new
String(request.getParameter("name").getBytes("iso-8859-1"),"iso-8859-7");

Re: OutputStream insteat of an PrintWriter

[Hoorn, Michiel van]

This is our code. Maybe you can use some of it.

  // output stream
  java.io.StringWriter foStringWriter = new java.io.StringWriter();
  StreamResult foDoc = new StreamResult(foStringWriter);

  // Transform XML to FO-XML
  XMLTransformer transformer = new XMLTransformer();
  transformer.transform(_xml, _xslFilename, foDoc);

  // Setup FOP Driver
  Driver driver = new Driver();
  driver.setRenderer(Driver.RENDER_PDF);
  driver.setOutputStream(_outputStream);

  XMLReader reader = XMLReaderFactory.createXMLReader();

  System.out.println(foStringWriter.toString());

  InputSource foInputSource = new InputSource(new
StringReader(foStringWriter.toString()));
  driver.buildFOTree(reader, foInputSource);

  driver.format();
  driver.render();

Re: jsp - html editor

[Glenn Wearen]

Yes JRun is a container, but does JRun add additional functionality to
UltraDev? if I use Tomcat/iPortal/WebSphere instead of JRun will my JSP-HTML
development in UltraDev be the same or not?

Thanks for clarification

PS: Why anybody would want to strap JSP onto IIS I don't understand,
especially in light of recent IIS bugs.

Re: Browser Incompatibility

[Glenn Wearen]

I also have a problem in Browser inconsistency, I use a JSP scriptlet to
populate the options in a select list, the resultant HTML look like this...



 All Active Requests

 All closed
requests for my project

 All closed requests
for my team


in IE the select list looks fine, in NS4 the list contents appear one after
another in what look like a box.

Re: jsp - html editor -DB connectivity

[Glenn Wearen]

I I correct in my understanding that the DB connection wizard in UltraDev
generates JavaScript to do the DB fetches etc?
if so, aren't DB connections better done server-side with a JSP/Servlet?

Custom tag or beans?

[Glenn Wearen]

I'd like to hear the for and against arguments for which is better...

"Write your won JSP custom tags or create your own JavaBean".

To do things like get Data from a database, format db data in XML etc.

Glenn

PS: I've never seen CFML before, does it look like JSP custom tags?

Re: Custom Tags or Beans

[Glenn Wearen]

I forgot that most people in this list are not in my time zone, so I got the
low-down on Tags Vs Beans myself.

I found  http://java.oreilly.com/news/jsptips_1100.html 'Choosing Between
Beans and Custom Actions' had a fair discussion about it, also this lists
archive had some debate about the topic before, somebody pointed out that
one of best  reasons for using custom-tags is that it allows web-developers
who don't understand Java to write JSP.

apologies for anybody who took time to respond to my question, my minds made
up to stick with beans because it suits ME!

VERY VERY URGENT

[paramjit singh]

hi!
this is a very urgent so please reply withing 1- 2 days.
I have used java.util.Random.nextInt(upperlimit) function which generates
integer random numbers
form 0 to upperlimit specified. This function i am using inside an applet
which is emmbedded in an html page
when i use that html page with appletviewer then it works fine but when i use
it within internet explorer it gives 
following error:-
error:- java.lang.NoSuchMethod error : java/util/Random: method nextInt(I)I
not found 
in its status area
so my applet doesn't loads .

So which other function can do the same objective or what else i can use ??
I am using internet explorer 5.0

Thanks in advance.

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.

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: Custom Tags or Beans

[Bryan LaPlante]

One thing to Consider about custom tags that is not to do with programming
as much as communications. If any one is working in a team environment and
creates a component the matter of documentation is less complex if you are
describing a list of parameters as apposed to describing the methods and
properties of the component. One additional resource available to users of
the JRun or Cold Fusion Studio products is the ability to describe a
component in vtml (visual tool markup language). In the UltraDev family of
editors you can right click on a custom tag described in this manor and
choose a visual editor that displays the parameters and optionally has
inline help documentation if it was created that way.

I know it is a hassle to learn yet another markup language just for the
purposes of describing your controls so about a year ago I wrote a custom
tag wizard to help me quickly create those tag editors. The tag wizard was
written for Cold Fusion before I stated making the transition to JSP and as
soon as I get some additional time on my hands I plan to update it to
accommodate more of the JSP stuff. Below is a link to an article about it on
Allaire's site. The tag wizard is free to the public.

NOTE: to use the tag wizard to create xml style tags for your custom
taglib's you can still do it with these additional steps.

1. Enter the name of the tag without the prefix [ TEST ] not [ MYTAG:TEST ]

2. After you receive an email from the wizard with your custom tag disregard
the readme.txt file

3. Create a MYTAG directory under {%JRun Install%}:\Program
Files\Allaire\[%JRun% | %CF% ]\Extensions\TagDefs where %JRun Install%
refers to your install path of the editor and MYTAG refers to your custom
tag library name

4. Open the vtm file you created and edit the line.  where mytag refers to the name you chose for your
custom tag library.

5. To refresh the editor and load the custom dialog press CTRL+SHFT+ALT+C

6. Type in the name of your tag in the editor like  then right
click and choose edit tag.

AW: VERY VERY URGENT

[Michael Jager]

The java.util.Random.nextInt(int n)-method came with JDK 1.2 (Java 2).
Microsofts IE use a JVM 1.1.4 and so they are ignorant of this method!

You can use java.util.Random.nextFloat() multiplied with your upper limit
instead.

And allways remember when you are programming applets: don't use methods
that came with JDK 1.2 or later because IE won't show them!

By the way: This is a mailing list about Java Server Pages specification and
reference.
So maybe next time you would like to ask your questions about applets in an
appropiate list because you are more likely to get a quick answer there.

Re: Browser Incompatibility

[Jann VanOver]

Did you open and close the  tag correctly?  IE is will show you 
elements even with no  tag.  NS will not.  I think NS will even insist
on a valid "action" attribute in the  tag.

By the way, this STILL isn't a JSP problem.  This is basic HTML forms.

No. Use the right tool for each task: JSP is strictly for text output, servlets
can be used for both binary and text. So in this case you should use a servlet.

You *can* wrap your scripting code in try/catch/finally to deal with the
exception cases, but I don't recommend it. Too much code in JSP pages causes
both debugging problems and a maintenance nightmare down the line.

A better approach is to use either a servlet to do all database access
and forward to a JSP page for generating the response, or use JSP custom
actions for the database access in the JSP pages. There are plenty of
custom tag libraries for this available, so you don't have to roll your
own. A couple of examples of implementations you can use for free, with
source code available:
* The example tag library for my JSP book:
  
* The DbTags library from Jakarta:
  

A commercial example is the InstantOnline Basic product my company sells:
* 

And if you search the web, I'm sure you can find a lot more.

User authentication/session management with JSPs/Resin

[Abhijit Hiremagalur]

Hi All,

Has anyone used the Authenticator in Resin 2.0.0?

If you have could you please briefly explain to a complete novice at
JSP(though I am familiar with java itself), a good approach to user
authentication, possibly using this Authenticator interface providen in
Resin.

Are there any other alternatives that are not container specific?

Am I way off track here? If so could you direct me to a webpage/resource
where some simple user authentication and session management with JSP is
demonstrated.

Thanks in advance, This group has been most helpful in the past. My
apologies for crowding the list with such basic questions.

Cheers

Abhijit.

Re: cannot resolve symbol

[c2yh]

Actually Java does not care how you name your classes!
As long as you call the java class with its EXACT name.

so, if you name it "DefaultXYDataSource", you must use it as
"DefaultXYDataSource".
The "DefaultXYDataSource.class" must be put in your CLASSPATH folder.

There are 2 main reasons for "cannot resolve symbol" error:

1. the "DefaultXYDataSource.class" is not in your CLASSPATH folder.

2. You name it as "DefaultXYDataSource" but you call the class by some
other names in your script.

Yes, this is a real bitch in Servlet 2.2. The best you can do is use
different URI patterns: one for all links in your applications that
maps to the authentication servlet, and another that maps to your
real servlets (and/or JSP pages). For instance, use this for mapping for
your EntryServlet:

  
entry
/protected
  

and something like this for all your real servlets:

  
myRealServlet
/real/myRealServlet
  

Now a request for /protected/myRealServlet is handled by your entry
servlet, and the entry servlet can use the RD to forward to
/real/myRealServlet.

To prevent your real servlets to be accessed directly, define a
security constraint for "/real" so that they only can be accessed
by a role that is not assigned to anybody. Access through the RD is
not subject to access control, so your servlet can still forward
to the real servlets.

I know, this is not what you wanted. But it's all you can get in Servlet 2.2
if you stick to the standard API.

The solution you're looking for is provided by filters in Servlet 2.3. They
were added for exactly this purpose (plus a lot of similar scenarios). You
can read about filters in Jason Hunter's JavaWorld articles:

I'm not sure I follow. The ServletContext.getRequestDispatcher() method
takes a context-relative path (starting with a slash) so it's not relative
to the request URI at all. The ServletRequest.getRequestDispatcher()
method takes a path that is relative to the current request URI. But in
neither case is there a file name involved; only URIs.

I hope this helped.

Javadoc for TagLibs?

[Mattias Jiderhamn]

Bryan LaPlante just told us about his tool for making vtml descriptions
for JSP custom tags/taglibs.
Does anyone know of (or has made for their own use) a tool for creating
documentation for the tablibs? Like a JavaDoc for taglibs.

It would be nice if the tool read the JavaDoc in the tag source and the
tld and created (or outlined) something like the Jakarta taglib docs,
such as http://jakarta.apache.org/taglibs/doc/dbtags-doc/index.html
Does anyone know how these are made? By tool or manually?

OutputStream insteat of an PrintWriter

[Thomas Wittpahl]

I want to send a PDF - File, which is generated by a Bean, to the Client. I have to 
send an byte[] back, but only an OutputStream can handle this.

--- JSP - CODE ---

response.setContentType("application/pdf");
ServletOutputStream out = res.getOutputStream();
out.write(eng.getPageData(1));

--

eng.getPageData(1) -> byte[]

Can I generate an OutputStream instead of a PrintWriter? - It does not work to 
generate an OutputStream and an PrintWriter!

Is it possible give the JSPCompiler a parameter, that generates an OutputStream 
instead of the PrintWriter?

Thanks.
