JSP FAQ Resource Information
This is a weekly informative posting to the jsp-interest list. Before asking questions of a general nature, please check out the resources available online to see if your question already has an answer. The best place to start is our web site: http://java.sun.com/products/jsp Some FAQs that may help you http://java.sun.com/products/jsp/faq.html http://www.esperanto.org.nz/jsp/jspfaq.html http://www.jguru.com/jguru/faq/faqpage.jsp?name=JSP http://www.jguru.com/jguru/faq/faqpage.jsp?name=Servlets The archives of this list are available at: http://archives.java.sun.com/archives/jsp-interest.html Tomcat is the reference implementation for the latest JSP and Servlet specs. You can download Tomcat from the Jakarta project's website: http://jakarta.apache.org. For feedback and discussion on Tomcat, please use the mailing list [EMAIL PROTECTED] A few notes about the use of this list. We at Sun enjoy hosting this list to give everyone a forum to discuss JSP, servlets and related technology. There are a few things that we ask of you, the list members: Please don't engage in advertising. We like to hear when new products are announced and a link for all the information. What we don't like are lengthy press releases, advertisements, and other material which falls under the umbrella term "marketing". There is no problem in stating how your product compares to another, but remember, this isn't run by Sun to be an advertising forum -- but as a technical forum. Please don't post attachments to the list. The use of VCards and S/MIME is not really needed on a list like this and is annoying to some whose readers don't support them. More serious is the posting of .zip files and other larger items. You might get flamed a little bit for S/MIME or posting in HTML. You will be removed from the list for posting a .zip or other archive file. If you need technical support from a vendor, please contact that vendor directly.

Subject: Pass Parameters and Nested Jsp Question
Hi all
I have a question as the following
I have three jsp files , they are 1.jsp, 2.jsp, 3.jsp. 1.jsp will include
2.jsp and 2.jsp will include 3.jsp.
In 1.jsp
jsp:include page="2.jsp"
jsp:param name="aaa" value="AAA"
/jsp:include
In 2.jsp
jsp:include page="3.jsp"
jsp:param name="bbb" value="BBB"
/jsp:include
So in 3.jsp, we can use request.getParameter("bbb") to get the parameter
value,
if we still can use request.getParameter("aaa") to get the parameter value
passed by 1.jsp. Thanks.

I have implemented a solution similar to that, create a table to store details such as sessionId, User Ip, User's unique login id, session created time etc., check the table for login id, if not found, create a new session, add the loginid to that table and deny new session if the login id is found in the table. so, if the same user or anybody with the same loginid tries to sign again is redirected to another page which shows the details such the session details from the table This method works as long the user signs out using another jsp page which removes all cookies and invalidates the session, but the probelm is that if the user closes the browser window without signing out, those details are never removed from the table and he will not be able to login at all unless someone removes his details from the table Here, I am looking for a mechanism 1. which allows the tomcat container to remove all expired sessions from using sessions Ids, 2.

Hi,
I created a connection pool under weblogic 5.1 server as below.
weblogic.jdbc.connectionPool.bscsPool=\
url=jdbc:weblogic:oracle:IPAdd:Port,\
driver=weblogic.jdbc.oci.Driver,\
initialCapacity=4,\

weblogic.allow.reserve.weblogic.jdbc.connectionPool.bscsPool=everyone
weblogic.allow.reset.weblogic.jdbc.connectionPool.oraclePool=everyone
weblogic.allow.shrink.weblogic.jdbc.connectionPool.oraclePool=everyone
The connection pool is created. When I am trying to access it from my
JSP
as
below.
try
{
Context ctx = null;
System.setProperty("java.naming.factory.initial",
"weblogic.jndi.WLInitialContextFactory");
System.setProperty("java.naming.provider.url",
"t3://127.0.0.1:7001");
ctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource)
ctx.lookup
("bscsPool");
conn=ds.getConnection();
stmt = conn.createStatement();
System.out.println(conn);
}
catch(Exception e)
{
out.println("Could not connect to the database"+e);
}
I am getting the error as
java.security.AccessControlException: access denied
(java.util.PropertyPermission java.naming.factory.initial write)
Should I set some permission for the JSPs?
Thank You

Peter Pilgrim wrote: How do get a JSP to write a properly formatted CSV file? Is there a way to make JSP stop adding new lines or spaces? Can JSP pack spaces tightly between % .. % and tag .../tag? JSP follows the lead from XML with regards to line feeds: they are preserved but ignored. So the trick is to make sure you don't add any line feeds in the JSP page where you don't want them. In your sample, you have a line feed character after all JSP directives and action elements. When the JSP container processes the page, it consumes the JSP elements but adds the line feed characters to the response. By placing ending and starting the JSP elements on the same line, you get rid of all of the unwanted line feeds: %@ taglib uri="/orataglib" prefix="ora" %%@ taglib uri="/emistaglib" prefix="emis" %%@ page import="com.ora.jsp.util.*" %%@ page import="com.ora.jsp.sql.*" %%@ page language="java" contentType="application/vnd.ms-excel" %jsp:useBean id="detailBean" class="com.db.gdd3.emis.report.ReportDetailBean" scope="request" / ... and so on for all JSP elements. I describe this in Chapter 12 of my book, in relation to WML since WML browsers are sometimes picky about this stuff. Conversely can JSP be to told print a new line directly ( java.io.PrintStream.println() )? Any line feed in the JSP page is preserved, so just put a line feed where you need it. In a custom action tag handler or a bean that writes to the response, you can use JspWriter.newLine(); --CUT-- -- This e-mail may contain confidential and/or privileged information.

Pointers on JavaDoc-ing JSPs
Hi. I'm wondering if anyone has any pointers about how to document and comment code in JSPs so that they can be read and parsed by JavaDoc. I don't think you can have the JavaDoc tool examine JSPs themselves but perhaps it's possible to generate JavaDoc from the servlet code generated by the servlet/JSP engine... but that would require JavaDoc comments being included in the JSPs in some ways. Does anybody have any experience on that? Don't you think JavaDoc should be able to generate from JSPs as well as pure Java code files?

Re: jsp object(Param) and javascript
Javascript code on the client cannot access Java objects that were created in the JSP page on the server! The link that I gave you shows you how to create javascript code using jsp, BUT the jsp code itself is only executed at the server and the javascript code that is dynamically built by the jsp code is only executed on the client, so the two technologies cannot share objects (I think the web article clearly explains this). I you want the client to access Java objects, I think you'll have to use applets instead somehow. So, if you want the browser to send back data to the jsp on the server, here's how Hans says you need to do it in the article: "To only way to pass data from the browser to a JSP page is to pass the data as HTTP request parameters.

refresh of Session scoped beans
Hi all, A recent thread out here has me playing with the "scope" attribute of the jsp:useBean tag. Unfortunately, I have hit a wall. When using a bean of scope="session", which is populated from an HTML form using a jsp:setProperty name="foo" property="*"/. The initial population of the bean is OK, however when I hit "back" on the browser to make corrections to the form data, subsequent updates of the beans information are not successful. This is alleviated by using a bean of scope="request", however that is not what I need. Anyone encounter this problem and have a solution???

Re: jsp object(Param) and javascript
The point is any JavaScript code can get the value of Java object, but you
can not alter those java objects by javascript. if you like to do the work
like
% String name = javaObject1.getName(); %
function myFunction()
{ var name = %= name%;
name = name+" test";
if (document.yourForm.yourName.value != name) return false;
return true;
}
it's legal for you to do it, but if you try to change %= name% by
javascript, it's not possbile, because it's already processed by the server.
use "view source", you will see %= name % part has been replaced by real
value.
I guess it's how you interpreted "access". Using Applet is another story,
the fact is how many application still using applet

Re: jsp object(Param) and javascript
I think we're getting confused on what i mean by 'access'. When I mean 'access' I'm talking about directly getting a pointer to the object's address in memory, not about evaluating a expression and assigning that value to some other variable or expression. Hans' article talks about passing a variable's VALUE from jsp code to javascript code, BUT not the object(i.e., variable) itself. Do not get confused between a value returned by a method in a Java object with the Java object itself - they're not the same thing. -Original Message- From: Yan Zhu [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 01, 2001 8:46 AM To: [EMAIL PROTECTED] Subject: Re: jsp object(Param) and javascript Hung Yee wrote: Javascript code on the client cannot access Java objects that were created in the JSP page on the server! but I did.

Re: refresh of Session scoped beans
Hi, Thanks for the response. The exact syntax of the page is: jsp:useBean id="foo" class="Bar" scope="session" jsp:setProperty name="foo" property="*"/ /jsp:useBean So I think the bean is created correctly (?). This initial form/bean combination is then forwarded on to a confirmation page where the user can validate that what was entered is correct (at this point, the data entered into the form is retrived from the bean, so the intial creation/loading appears to be OK). The problem occurs when the user hits "back", updates the form and hits submit for the second time. The confirmation page does not reflect the changes made to the session beans properties. -Pete -Original Message- From: Kevin Jones [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 01, 2001 12:31 PM To: [EMAIL PROTECTED] Subject: Re: refresh of Session scoped beans Where are your setProperty elements If your page looks like this jsp:useBean scope="session... jsp:setProperty ... / /jsp:useBean That's exactly what I'd expect.

In fact, I have a ejb created on a totally different server, and I got the remote interface, persisted that in http session, and called it from javascript, and got the right value! Most likely, what you really did was generate the JavaScript code in a JSP page, and a part of the JavaScript you generated was a statement that assigns a value to a JavaScript variable, using JSP scriptlets to get the value from a Java object. Something like this: script language="JavaScript" // JavaScript code var myVar = "%= someSessionBean.getSomeValue() %"; /script As far as JSP is concerned, this is just template text (all the JavaScript code) and a JSP expression. When the JSP page is processed, all template text is sent as is to the browser, along with the result of executing the JSP expression (on the server). The result could look like this: script language="JavaScript" // JavaScript code var myVar = "foo"; /script Note how the JSP expression has been replaced with the value resulting from executing the Java code in the expression. When this response reaches the browser, the browser executes it and myVar gets the value "foo". Even though it may appear that you assign the value of a a Java object directly to a JavaScript variable, the fact is that you don't, as this example shows; you generate parts of the JavaScript code, containing Java object values, on the server, and the real assignment takes place in the browser when the result is executed. And by then, it's just a simple string assignment. I hope this makes it clearer what's going on.

Re: jsp object(Param) and javascript
Don't be too dispointed, I may have a solution for your problem. I think you
can have an input field in the form and have your parameter in that field
and the request will send it for you, on the javaside, use
request.getParameter to get it, look like that, at client site:
function assignValue()
{
//do some other job
var changeTo = "value";
document.myform.name.value = changeTo; // do your script logic here
return true;
}
form method="post" action="..." name="myform" onsubmit="return
assignValue()"
input type="text" name="name" value="%=whateverhere%"
On the java side, you simplely need as you always to with others:
String name = (String)request.getParameter("name");
you can get what ever value you have assigned in your javascript function.
So if your question is how to pass a dynamic value to the server, I guess
the trick is reset the value in your script function right before you submit
the form. Therefore, although you see the value of the form looks "3", but
the value may be well changed to whatever you want when it arrives the
server.
Hope it answer your question

A recent thread out here has me playing with the "scope" attribute of the
jsp:useBean tag. Unfortunately, I have hit a wall. When using a bean of
scope="session", which is populated from an HTML form using a
jsp:setProperty name="foo" property="*"/. The initial population of the

I solved the problem "resetting" the bean.
Instead of the useBean tag, i use:
myBeanClass bean = new myBeanClass();
session.setAttribute("id bean istance", bean)
So each time u acces to this page, the bean is resetted to the deafult
value.
After this, u'll have to put the setProperty * tag to initialize the bean
with the new values submitted.
P.S.: Remember that using the setProperty * feature, the corresponding set
methods are called only if the corresponding form field is not empty. I
mean, if u fill submit the form, then u come back, delete a field and then
submit again, the field u deleted won't be set to a null value in the bean
but it will keep the old value. It's better to use manually the set property
methods: bean.setProperty1("value") for each fields of the form.
Thanks for the reply.
I agree that this will solve the problem, but at the same time doesn't that
defeat alot of the "convenience" associated with the JSP/Beans combo? For a
large form, that is alot of bean.setProperty... calls.
I wonder if there is a better way?
Thanks for the heads up on the blank form fields are not set to null thing.

Re-execution of servlet
Hi All, I am describing my situation below. I have a page called AddTicket.jsp, which sends all the ticket related data entered by the user to the servlet AddTicket.java. Now AddTicket.java creates a new ticket id by fecthing the maximum ticket id from the database and adding 1 to it. Then AddTicket.java inserts the record which consists of parameters received from the jsp as well as the ticket_id generated. If the insert is successful then it sends a message to the message page using the following code ServletContext sc=getServletContext(); RequestDispatcher rd = sc.getRequestDispatcher(/jsp/Message.jsp); rd.forward(req,res); Now when the record is inserted then the Message is displayed on the message page whereas the URL on the browser is still that of the servlet. When I press F5 at this juncture, the servlet AddTicket re-executes thus creating another record with the next ticket id but all the data is same as the previous one.

There is, and I believe someone else already suggested it: move the
jsp:setProperty element out of the body of your jsp:useBean action.
If you have it within the body, it's only executed when the bean is
created. Since you create a session bean, the bean exists on the second
request. Hence, jsp:setProperty is not executed the second time.
If you move it outside the body, it's executed even when the bean exists:
jsp:useBean id="userInfo" class="com.foo.UserInfoBean" scope="session" /
jsp:setProperty name="userInfo" property="*" /
Thanks for the heads up on the blank form fields are not set to null thing.
I'm sure that would have bothered me in the future.
One way to solve this is to add a setReset(String foo) method to your bean
that resets all bean property values to their default values (e.g. null).
Then add a jsp:setProperty action to call it before you set the properties
based on the new request parameters:
jsp:useBean id="userInfo" class="com.foo.UserInfoBean" scope="session" /
jsp:setProperty name="userInfo" property="reset" value="anything" /
jsp:setProperty name="userInfo" property="*" /

ZHU Jia [EMAIL PROTECTED] 01/31/01 07:56AM Hi there, we have used Perl/CGI for years in our company, now we are considering switch to JSP/Servlet. I've had some early experiments with JSP (Tomcat 3.2) and I'm convinced that this is better than CGI. Now my question is which JSP Engine/Java Application Server should we use in our production environment? I only tried out Tomcat, it's OK and it's free, but is there anything better out there, considering the stability/ease of configuration/feature/price?

Transaction Handling..
This might not be a JSP related issue. But however if anyone knows more
about this please respond. I've an application where in once use logs in
his connection object is stored in a session and this is fetched whenever he
inserts/deletes/updates the database. To control transactions I did the
following (as mentioned in Jason Hunter' Servlet Book)
conn.setAutoCommit(false);
try{
...
stmt.executeUpdate(sql1);
stmt.executeUpdate(sql2);
..
//If success
conn.commit();
}
catch {SQLException e) {
// Error
conn.rollback();
}
finally{
conn.setAutoCommit(true);
}
But when I try to issue a conn.setAutoCommit(true) it gives the following
error
"SET CHAINED command not allowed within multi-statement transaction)". I'm
using jConnect5.2 as the database driver. I've explored most of the avenues
and I really appreciate if anyone can suggest some method in which I can
turn the transaction back to "true". I'm using Apache/Tomcat setup.

Not to rain on your parade, but both these products only let you use JavaScript as the scripting language in a JSP page instead of Java. My understanding of what Yan wants to do is let code running in the browser call an object living on the server, so replacing one server-side language with another doesn't help him (probably it just adds to the confusion). The only way to let code in the browser invoke some object on the server is by making a new request. One way of doing this is through an applet, as someone else suggested, but it still requires a new HTTP request, served by a special servlet (or JSP page), or a remote call to an RMI server, or something similar. There's no way to assign a client-side JavaScript variable a direct reference to a server-side Java object, or a server-side JavaScript object for that matter (if you use Rhino or BSF). Something is always needed to bridge the two execution environments, And that's true no matter which language or server-side technology you use (Perl-CGI, ASP, ColdFusion, etc).

Re: Editable Combo Box

Thanks for the quick reply
you can enter values in combo box with Javascript:
function addValues(value,text) {
document.FORM_NAME.COMBO_NAME.options[document.FORM_NAME.COMBO_NAME.options.
length] = new Option(value, text);
}
But the requirement is that user should be able to type in some values
or
Select from the combo box using only one control...So we cannot
provide another text field and
then add to combo box. Actually there is no requirement to add into
the list of combo box...
Hope u understood the requirement
Is any other way to handle this.
