Standard Javabean inside a JSP/EJB application

Hello!
I want to use a JSP-file as a graphical user interface for a j2EE-application. I want to use a standard Javabean as an intermediate connector between the JSP and the Enterprise Java Beans.
Deployment details:
- 2 bean-Jars inside a EJB-module
- A JSP-file inside a .WAR-file
But what about the standard Javabean, where shall I put it?
What are the correct settings in the deployment tool?....
bye from
G�ran, Stockholm

You just need the standard JavaBean available to the EJB as well as the JSP. One nice way is to package such beans into a JAR and include the JAR in the EJB module as well as the WAR as a library.

Standard method of storing config info in an EJB application

HI,
What is the standard way of storing config information in an EJB application?

Using JavaBeans in a JSP Page

I wan't to know the advantages and disadvantages of using JavaBeans in a JSP page.
Like for example general traditional approach for a database connection
is to create a connection and access the database from that and close the connection
at the end of the page, instead of the If I use a common connection bean for making connections,
is that suggestable and then when should i close the connection then.
One good application of JavaBeans is using a Set and Get methods for form fields in
a registration form to get back the values.
So may i know how best can we use the JavaBeans other than this application.
ThanX in advance,
kiran

I believe putting processing and query code in the JavaBean was one of the reasons for putting JavaBeans support in JSP in the first place. The original idea was to use the setXXX methods to populate the bean's data from the posted form, then do the processing (or database query), then use the getXXX methods to display the bean's data.
Efficiency-wise, it's exactly the same as putting all the code in-line in the JSP page (actually, it might be a bit slower, because of the reflection required to do it.) Code-wise though, it makes the JSP easier to read.
Of course, we have EJBs now too, which tie very closely and can match database queries almost one-to-one, one way to incorporate these is inside the JavaBean you reference from the JSP, another way from a servlet you redirect the JSP to, etc...

I used tag to show PDF file inside my JSP page, It is working properly in IE but nothing shows in Mozilla. What should I do?

I've used to display a PDF file inside my JSP page. It is working fine in IE. However, many of users of this application are using Mozilla and the platform is Ubuntu so it is vital that the file is shown in Mozilla as well. How can I solve this problem.
== This happened ==
Every time Firefox opened
== I run my jsp page

Such conditional code will only work in IE and not in other browsers like Firefox.

What is the directory structure of EJB applications?

I am new to EJB program. I know that after the development is done, we package the EJB components into .jar file, and package the Web components (HTML/JSP/Servlets/JavaBeans) into .war file, and then together we package .jar file and .war file into a single .ear file. Then we just deploy the .ear file into WebLogic's application directory.
But, before the deployment, I mean during the development, what kind of directory structure is good for us to develop our EJB, HTML, JSP, Servlets, and JavaBean components?
Previously, when I was doing JSP/Servlets applications, my directoy structure is:
webapps\
--------myapplication\
-----------------------*.html
-----------------------images\
------------------------------*.jpeg, *.gif
-----------------------jsp\
------------------------------*.jsp
-----------------------WEB-INF\
------------------------------web.xml
------------------------------classes\
-------------------------------------Java Servlets located here
-------------------------------------beans\
-------------------------------------------JavaBeans are located here
Now, I am doing EJB applications, what should be the directory structure?
Thank you very much for your help!

I have been involved in a few enterprise applications but have not been happy with the packaging structures used and am starting a new one now and am looking for other examples.
this is what I've used before.
web/
classes/
client/
server/
but if a class was used in the client and server it was put under the server/ package. I feel that more separation is needed.

Frame issue in jsp/struts application

I have a problem with jsp struts application .
i have a jsp page which is inside a frame .
The action class which receives the request from this page redirects the request to another jsp page.
I want this new jsp page to be displayed without any frame , but it is getting displayed from inside the frame .
can anybody help me out ...
regards,
slam

Possibly:
1. Browser could be caching the page.
2. If you use a proxy, the proxy may be caching the page.
3. The page is not getting recompiled.

Calling an EJB application in webdynpro

Dear SDN's,
I am trying to call an EJB application from a webdynpro application and is succeded in storing values to database via Java Bean Model.
I want to retrieve all records from table via EJB and all the records should be displayed in Webdynpro Table UI element.
How can we do it?
The problem here is, how to return a set of records to webdynpro from EJB via a javabean.
I am not clear in using Collection Framework! i.e, which collection class i have to use to store the retrieved records.
Your help will be appreciated.
Regards,
Sireesha.B

Hi Sireesha,
Instead of adding resultset, create a EMP cinstance and add it.
Ex : Consider you have created a EMP class
class EMP
String empname;
int id;
public void setEmpname(String name);
public String getEmpname();
Now
ResultSet rs=statement.executeQuery(select * from emp);
Vector v=new Vector();
while(rs.next)
Emp e=new EMP()l
e.setEmpName(rs.getString(0));
e.setID(rs.getInt(1)));
v.add(emp);
Iterator i=v.iterator();
while(i.hasNext())
Emp e1=(EMP)i.next()l
System.out.println(e1.getempName());
System.out.println(e1.getID);

Multiple form inside one jsp file

I have to use nested jsp forms in my latest project
ex:-
<html>
<head>
</head>
<body>
<form id="form1" name="form1" method="post" action="ex.htm">
<form id="form2" name="form2" method="post" action="ex2.htm">
</form>
<form id="form3" name="form3" method="post" action="ex3.htm">
</form>
</form>
</body>
</html>
Can some one tell me, is there a way to submit the each forms seperatly?
-----------------------------------------------------------------More on problem-----------------------------------------------------------------
I am developing e-savings application.
When the customer enter the accountno i need to display details - for this i use "form1"
When the customer enter the withdrawal amount i need to display the balance - for this i use "form2"
Finally i use "form3" to submit the data.
I have done all the things inside one jsp page.
I think you are now clear in my problem and hope best solution....
Thank you........

According to the HTML specification, you may not nest forms.
You can use multiple forms as long as you don´t nest them.

How can I import a servlet inside a JSP?

Hi! I have seen tons of instructions on importing beans inside a JSP page but I want to use servlets instead. This question might be stupid, but I'm not really adept with JSPs yet and I hope you can help me.
I need to import classes inside my JSP page so that I can use the methods and manipulate them through the JSP.
Thank you!
lauramos

I'm curious, have you looked into using the MVC or Struts framework? One idea would be to map the Servlet you created to a JSP via XML (or any other mapping you want #?.jhtml for all that matters) and jsp:include as needed. Just a few mappings needed in WEB-INF/web.xml for instance...
<servlet>
��<servlet-name>HeaderPageHandler</servlet-name>
��<servlet-class>packagename.HeaderPageHandler</servlet-class>
</servlet>
<servlet-mapping>
��<servlet-name>HeaderPageHandler</servlet-name>
��<url-pattern>/header_page.jsp</url-pattern>
</servlet-mapping>
In the JSP:
<jsp:include page = "header_page.jsp" flush = "true" />
The Servlet could forward the information over to another page using the getRequestDispatcher(String url).include(req, resp); From there, use the application or request scope to handle the jsp:useBean to output what you need. You could take that further and customize some of your own TLDs so you could state simple tags like <tag:output class="text">some text here</tag:output>

Missing EJB application and tutorial sample in workshop 8.1

HI,
I just installed workshop 8.1 from the BEA CD. I wanted to follow the EJB tutorial
that's available in e-docs on the web, however, i don't see the Enterprise JavaBeans
tutorial (the Band example) in the list of new Applications (under tutorial).
I also don't see a new application template of Enterprise javaBeans under 'All'
(not sure if there should be one).
Could someone please let me know why I'm missing the Enterprise javaBeans tutorial
and how I can get it? Also, why don't I see an application template for EJB Application?
Thanks,
Prab

My ejb application can't see jar files

I am using JBoss 2.4.3 as my EJB server. I have followed the instructions in the documentation about making jar files visible to my ejb application. ie, I have an ear file with the following contents:
meta-inf/application.xml
meta-inf/Manifest.mf
myEJB.jar
myWAR.war
lib/myUtilities.jar
The classes inside myEJB.jar reference classes inside myUtilities.jar. The myEJB.jar contains a manifest file that looks like this:
Manifest-Version: 1.0
Created-By: Ant 1.4
Class-Path: lib/myUtilities.jar
But the classLoader spits a dummy and gives me a NoClassDefFoundError when the a method is called in the ejb that references the classes in myUtilities.jar. And yes, there is a carriage return after the Class-Path line. I've also tried it with ./lib/myUtilities.jar but with no luck. And I've tried putting it into the myEJB.jar, which (expectedly) didn't work.
The only way the classes in myUtilities.jar can be visible is by putting the jar into the jboss lib/ext directory, which is not recommended.
Any help is desperately appreciated.
Thanks

ThanksHi
Can you please try placing your "myUtilities.jar" in the root.
I mean your ear file with
myEJB.jar
myUtilities.jar
And dont forget to add the following entry in
meta-inf/Manifest.mf in your myEJB.jar
Your meta-inf/Manifest.mf shld consist of
Class-Path: ./myUtilities.jar
I think this can solve your problem
