JSP help: A bit off topic
Hi, This doesn't exactly relate to Tomcat, but it is a general JSP query. You see, I am using a set of Java classes, packaged as CTG (CICS Transaction Gateway) provided by IBM. My problem is, I am able to instantiate a CTG object inside the JSP. For example, in the JSP, if I write html blah blah blah % CTGClass ctgObject = blah blah blah . % b%=ctgObject.getSomeString()%b This works fine. But when I write all this code inside my class, and say html blah blah blah % myClass myObject; myObject.getSomeString() /* This will actually contain all the code in JSP, just to avoid the JSP page cluttered with Java Code */ But this doesn't work. This problem is not only with CTG but many other classes, too. One interesting observation is, if I add a main to myClass and run it from the command prompt, it works perfectly. Any help?

RE: JSP help: A bit off topic
Hi, You should not *have* to use a useBean in order to instantiate a class. I did not see in the example you posted, where you actually created an Object.. your code was : myClass myObject; myObject.getSomeString() /* This will actually contain all the code in JSP, just to avoid the JSP page cluttered with Java Code */ .. but no-where was there a myObject = new myClass(); ie : myClass myObject = new myClass(); myObject.getSomeString() until you do this, there is no object, just a ref, so you can't call methods on it.

RE: JSP help: A bit off topic
myObject.getSomeString() /* This will actually contain all the code in JSP, just to avoid the JSP page cluttered with Java Code */ If you expect getSomeString() to return *JSP* code (including tags and scriptlets and all), you can't do that. The JSP code is compiled the first time you execute this page -- you can't create it dynamically at runtime. At best, you could have getSomeString() return some static HTML code and write it to the output stream: % out.println(myObject.getSomeString()); % However, embedding *any* of this stuff is really a misuse of the technology, because you end up intermixing business logic (what data am I manipulating) with presentation logic (how do I want this data to look) in ways that will lead you into unmaintainable spaghetti code that is very difficult to update later. A far better strategy is to use some sort of MVC architecture (such as Struts, http://jakarta.apache.org/struts/) and put your business logic in Java classes, and your presentation logic in your JSP pages or whatever. Let your business logic deal with the *data* (getting it from the database or whatever) and your JSP page deal with the *UI* (how it appears to the user).

RE: JSP Help
No, you don't want another print writer, you want to flush the implicitly
created printwriter named out that jsp creates under the hood.
If this doesn't help, I'm afraid I can't suggest anything more. I avoid JSP
like the plague.

Hi,
Thanks for your response to my question. I hope you don't mind if i take
this question off of the mailing list. It will be easier to talk directly.
Unfortunatly - i couldn't get it to work any better. Here is what i did:
In the included servlet i added the following lines after the /HTML tag
HTML
Included tags
/HTML
try {
java.io.PrintWriter pw = response.getWriter ( );
pw.flush ( );
}
catch ( ... ) { }
The result turned out the same.
I am using: java 1.4 and tomcat 4.0.4
Is this what you had in mind?
Again - thanks for your response.

This might not be the correct forum - but I am porting my application from Tomcat 3 to Tomcat 4 and I am having trouble with the requestDispatch.include ( r, r ) method. What happens is thet the includedjsp file gets included above the output from the parent jsp page. The parent jsp creates the HTML form ... with a servlet action handler and the include directive inserts the HTML controls that are appropriate for the situation into the surrounding HTML form. As the page is rendered by Tomcat 4, the HTML controls are not within the scope of the HTML form and the application no longer works.

jsp help
Hi, this may sound remedial but I was hoping someone can clear jsp up for me. Java Servelets are executed by inputting the necessary information in the web.xml. This would include the servlet name, servlet class name, and the name you want it to be called as when called from browser. This much I know about the servlets. However because I am new to JSP I don't how to set it up and execute. Is it similar to the servlet process? Do you even have to put in an entry in the web.xml file. The examples given with jakarta does clarify much because all of the examples are executed by putting in the directory and .jsp file name in the browser url, obviously you couldn't put the directory name when executing by requesting like this: http://localhost:8080/examples/file_name.jsp I am doing my research by reading books and all but I would also appreciate some feedback from the public.
Re: jsp help
Hello, Jeremy: If you are familiar with servlets - there isn't much more to know about JSP. JSP is a short-hand for generating servlets. Just few tags to learn. The advantage of writing JSP tags is that (in our case) apache programs: parser, compilers, loaders parse these tags, generate servlets, already familiar to you and load generated classes into the JVM. So this is all there is to it.

[Basic] JSP help!
1. How do you "redirect" a page? I have code that
if string == a then
forward to page 1
else
forward to page 2
Unlike ASP, the forward tag just sort of INCLUDES the file! The file name in
the browser is the same..not that of the file that I am forwarding to! What
is the command to really REDIRECT the page by changing the URL of the
current browser window?
2. How can I get the current path of the script? I mean something like
REQUEST.SERVERVARIABLES("SCRIPT_NAME")
or REQUEST.SERVERVARIABLES("PATH_INFO")
3. I need to know some string manipulation functions like substr etc...most
JSP books assume you know Java, where can I find a good beginner's reference
to all these functions?
I would really appreciate if someone can help! Thanks!

RE: [Basic] JSP help!
1. In a jsp you can use response.sendRedirect("URL") to send the browser
an instruction to open another page. Forward does like you say - totally a
server thing.
2. I believe it is request.getContextPath
3. Go to the Java site (www.javasoft.com) and go to their tutorial or search
on google for Java Tutorial and you will find a wealth of tutorial info.

Subject: [Basic] JSP help!
1. How do you "redirect" a page? I have code that
if string == a then
forward to page 1
else
forward to page 2
Unlike ASP, the forward tag just sort of INCLUDES the file! The file name in
the browser is the same..not that of the file that I am forwarding to! What
is the command to really REDIRECT the page by changing the URL of the
current browser window?
2. How can I get the current path of the script? I mean something like
REQUEST.SERVERVARIABLES("SCRIPT_NAME")
or REQUEST.SERVERVARIABLES("PATH_INFO")
3. I need to know some string manipulation functions like substr etc...most
JSP books assume you know Java, where can I find a good beginner's reference
to all these functions?
I would really appreciate if someone can help! Thanks!
