Integrate a JSP in Java?

i know you can do it the other way round..
but now i wonder, if you can also integrate/import a .jsp in a java-file.
thanks for help

getServletContext().getRequestDispatcher("/myPage.jsp").forward(request,response);
This line is taken out of a servlet, but you should be able to apply it just fine :)

Problem with JSP and Java Servlet Web Application....

Hi every body....
I av developed a web based application with java (jsp and Java Servlets)....

But when i upload on internet with unix package my servlets and Java Beans are not working .....

Plz gave me solution...
Thanx looking forward Adnan

You need to elaborate "not working" in developer's perspective instead of in user's perspective.

Is it possible to call the SQL Server DB from jsp to java?

im doing a configurable system where you can create your own table using the system. i can do the creation of table by running the statement CREATE TABLE...........(with attributes) in java.
Let's say i have created tblST1 with attributes st_ID, st_Name, st_Description.
My problem is i dont know if it's possible to retrieve all the attributes from jsp to java.

jverd: i need your help. Iv read all the links u posted but im having a hard time in understanding them.
For the site http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSetMetaData.html , there's a code there which is...
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
what i did was, i inserted it in my java code which is :
public boolean checkFieldTable2()
          boolean checked = false;
          try
               IRMS_DBConnect db = new IRMS_DBConnect();
               db.openCon();
               ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
          ResultSetMetaData rsmd = rs.getMetaData();
          int numberOfColumns = rsmd.getColumnCount();
          boolean b = rsmd.isSearchable(1);
               db.closeCon();
               checked = true;
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return checked;
and i compiled it and there was an error that the variable stmt was not initialized. Am i doing the right way?
Can anyone help me pls? pls pls pls

Questions/answers from jsp to java bean

Hi
This is what i need to do .
I am showing some questions, say 4 of them , and radio buttons(yes/no) as answers in the JSP.
Now how do i transfer these questions and their answers from jsp to java bean .
I did try hashmap ,but not quite working .
any help?
thanks

Name each radiobutton differently, and then provide 1 property and accessor methods for each of your four answers in the JavaBean, with the same name as specified in the HTML FORM.
So in the HTML:
<input type="radio" name="answerOne" value="true"...>
and then have a property named answerOne with accessor methods in the javaBean...

What's the relationship between JSP and Java?

hi,dear friends here.......^_^ I'm a graphic/web designer,
cause the needed of internet web design, I started to learn html and Java server page.But I never have experience of JAVA programs. It's kind of hard for me to know and use JSP now.Should i need to learn Java first? Or can anyone tell me what's the good way for me to
learn JSP?
I also want to learn how do make a web page as the first page of java.sun.com about "Industry News ".
Thanks !!grace from Taipei,Taiwan

Hi! JSPs allow Java code together with HTML in one document. The servlet engine "compiles" a JSP into a servlet prior to executing it. So, one must know Java prior to dealing with JSPs.
IMVHO, "Thinking In Java" by Bruce Eckel is a very good book for introduction to Java. You can download the electronic version at no charge from http://www.bruceeckel.com.
After you get a good handle on Java, "Professional Java Server Programming" (Wrox Press) can give you good information on servlets and JSPs, along with some other related topics.
Hope this helps!
Cheers!

Can we integrate .swf file in java script ?

Hello Friends,
We implemented one concept in Flex and now would like to integrate with JavaScript. Earlier we integrated an Applet code but now, we developed the concept in Flex, however, I am unable to integrate the concept in java script.
Can anyone help me out with the procedure to integrate flex swf file in java script ?
Here is my earlier java script code :
var file=gup('query');
//document.write(file);
var prevFile=gup('prevFileName');
//document.write(prevFile);
document.write("<table align=\"center\"><tr><td><applet code=\"MyApplet.class\" archive=\"Visual.jar\" width=1000 height=500>");
document.write("</applet></td></tr></table>");
function gup( name )
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return results[1];
Thanks in advance.

What version of FlashPro are you using? If you want a self contained app that doesn't load external resources, publish an AIR app, which will work on Windows or OSX. I'm using OSX so I can't really help with .exe projector files, but it looks like the latest version of FlashPro no longer outputs projector files—I think everything is AIR now.
If you really want to go the projector route, I'm guessing Jeffrey Smith's suggestion of finding an older version of Flash Player would be simpler.
So for AIR, set your Publishing target to AIR for Desktop. Then under File>AIR settings:
Output as: Application with runtime embedded
Include files: Add all of your resources—the swf ID generated and it's resource folder
In the Signature tab click New to create a self-signing Certificate (if you were developing commercial software you would need a third party certificate). You can save the certificate anywhere.
When you publish you should find an AIR application file (.app) file in the directory with your .fla

JSP vs Java Servelets

I realize that I'm probably in the wrong place, because I'm not a developer. However, I really don't know where else to turn for help. I used to work in the web dev industry in NYC, now I'm stuck in Little Rock, AR, and I don't know any "answer people."
I need some advice on whether to use JSP or Java Servelets for my ecommerce site.
I currently run my brick & mortar retail store on a Java-based Point of Sale (POS) system, with a MySQL relational database. It is a very upscale home furnishings/design store, so the design of the web site really matters.
My POS vendors have developed a web store interface using Java Servelets, but since the programmers developed it, there is little consideration for design.
It seems to me, based on my previous experience, that JSP would be the way to go here. I've got a great relational database - wouldn't it be best to have total flexibility in the way data is accessed & displayed?
If anyone out there can discuss this with me intelligently (without totally going over my head), won't you please help?
Many, many, many thanks!

myabigail, I dont know if you are still looking for an answer to your question. I read many good answers on the board already. Based on my many years of experience doing IT type work, I will say that there is a world of difference btw designing a page with servlets vs JSP's. While it is true that JSP's are eventually compiled into servlets, the difference btw them and servlets in syntax and use allows for true separation of concern. Most importantly for you as a business owner, using JSP allows you to create a web site that will be more easily maintained over time, for lower cost. This is because most time your business model will not change, whereas the look of your site will most likely update more frequently (as is typical with most sites). So after initially hiring a Java developer to write your business logic, and a web designer to build your web pages, you will thereafter only need the web designer for updates to your site. The main reason for this is that the bulk of JSP is implemented as a set of tags which look like the regular HTML that a web designer works with on a day to day basis. The learning curve for JSP is very short, most 'webbies' pick it up in a few months. I hope this (long) post helps you out in some useful way!

First use of jsp and java bean and "Unable to compile class for JSP" error

Hi,
I am trying to create my first jsp + java bean and I get a basic error (but I have no clue what it depends on exactly). Tomcat seems to cannot find my class file in the path. Maybe it is because I did not create a web.xml file. Did I forgot to put a line in my jsp file to import my bean?
Thank you very much for your help.
Here is my error:
An error occurred at line: 2 in the jsp file: /login.jsp
Generated servlet error:
[javac] Compiling 1 source file
/usr/local/tomcat/jakarta-tomcat-5/build/work/Catalina/localhost/test/org/apache/jsp/login_jsp.java:43: cannot resolve symbol

CMBConnect test = null;
I only have this in my directory:
test/login.jsp
test/WEB-INF/classes/CMBConnect.java
test/WEB-INF/classes/CMBConnect.class
Do I need to declare another directory in classes to put my class file in it and package my bean differently?
Here is my login.jsp:
<%@ page errorPage="error.jsp" %>
<jsp:useBean id="test" type="CMBConnect" scope="session" />

<title>my test</title>
</head>
<body>

</html>
and here is my CMBConnect.java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class CMBConnect
public CMBConnect () { }
public String openConnection(String id, String password) {
String returnText = "";
try {
Connection con = null;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
con = DriverManager.getConnection("jdbc:oracle:thin:@myserver.abc.com:1521:TEST", id, password);
if(con.isClosed())
returnText = "Cannot connect to Oracle server using TCP/IP...";
else
returnText = "Connection successful";
} catch (Exception e) { returnText = returnText + e; }
return returnText;
Thanks again!

Publishing JSP form JAVA stored procedure [Oracle8i 8.1.7]

Hi folks,
I wonder if anybody knows a way to publish JSP from JAVA stored procedure.
I know there is a way to load java class using PL/SQL package DBMS_JAVA.loadjava(), or
oracle.aurora.server.tools.loadjava.LoadJavaMain.serverMain() from java.
But I need somthing like publishjsp to translate the JSP.
Also would be nice if I can invoke this from a LOB where I have stored my JSP.
Any ideas?
Mitko

I case anyone is interested.
I managed to find out what I was doing wrong.
First when you call a stored procedure that is in a package and is a method of a class. You call it referencing the packagename.method. Leaving out the class name. Also, since this was a method that returns a value. The return value has to be assigned to a variable or used in an sql statement. Such as:
var x number;
call claimsprocedures.ip(19990033) into :x;call completed
print x;(then the value is displayed in sql*plus

Unable to compile JSP in Java Server

Hi:
I have installed Java Application Server Platform Edition 8 locally and attempting to run an application with a JSP. However, when it attempts to compile the JSP, I get the following message:
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.

I thought that Tomcat came with the implementation of the JAVA server. If so, why am I getting this message? Do I have to also install Tomcat separately? If yes, is there anything I need to know about port conflicts? Java Server is currently using 8080 for HTTP. Please advise as to how I can resolve this problem.

Jdeveloper toolbox - links fail with "Errors compiling:C:\jdevhome\jdev\myclasses\.jsps\\_OA.java"

Hi,
I'm running 12.1.3 in virtualbox and the OAF toolbox tutorials work after logging onto EBS.
After installing jdeveloper (on windows 8) and doing the documented setup, even the "Hello World" test fails when run in jdeveloper.
I've double checked the setup and that the jdeveloper patch version is right (p9879989_R12_GENERIC)
and have the "Default Local IP address" checkbox selected as well.
I guess some windows install/config is incorrect,but don't know what. Any ideas?
Thanks.
The exact browser error is -
