SQLJ and JSP

Hello,
I have generated a sqlj wrapper class for a package, and now I want to execute a method that calls the pl/sql procedure inside the .sqlj program thru JSP. How do I do that?
I tried <%=methodgenerated() %>, but doesn't work.
It's a stored procedure not a function. I looked for an example and I just found the runQuery() example everywhere, but didn't find an example about running a procedure from JSP.
I also did the steps about language="sqlj" and import.... but I need an example about doing this action.
Could you please help me with this?
Thanks in advance.

I will answer myself, so people that has the same problem can see this:
Make a jsp page (callingprogram.jsp) that calls the following file: EXECUTESQLJ.jsp (the file name could be whatever):
-- CALLINGPROGRAM.JSP --
<%@ page contentType="text/html;charset=windows-1252"%>
<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=windows-1252">
<TITLE>
jsp to execute a pl/sql (sqlj)
</TITLE>
</HEAD>
<BODY>
Ejecutar un PL/SQL es cuestion de colocar el codigo en JAVA respectivo:
<FORM method="post" action="executesqlj.jsp" onreset="alert('LA FORMA ES REINICIADA')">
Presione el boton --><INPUT type="submit" value="Ejecutar">
<BR>
Para Reiniciar valores presione ---> <INPUT type="reset" value="Reiniciar"></TD>
</FORM>
</BODY>
</HTML>
Then, the file EXECUTESQLJ.JSP should has a look like this:
<%@ page language="sqlj"
contentType="text/html;charset=windows-1252"
import="oracle.jbo.*,
java.sql.SQLException,sqlj.runtime.ref.DefaultContext,
sqlj.runtime.ConnectionContext,java.sql.Connection,
oracle.sqlj.runtime.Oracle,mypackage1.java2" %>
<-- mypackage1.java2 is the wrapper sqlj that the JDEV has created with the option GENERATE JAVA... -->
<HTML>
<HEAD>
<TITLE>
Executing sqlj....
</TITLE>
</HEAD>
<BODY>
<% // Codificacion de Java para llamar el procedimiento.
Oracle.connect(new java2().getClass(), "connect.properties");
<% /* remember creating the file connect.properties in your package directory
The file has to be like this:
sqlj.url=jdbc:oracle:thin:@servidor:1521:ORCL
# User name and password here (edit to use different user/password)
sqlj.user=scott
sqlj.password=tiger
*/ %>
java2 execsql = new java2();
execsql.testjava();
%>
<jsp:forward page="callingprogram.jsp" />
</BODY>
</HTML>
Hope this could help the jdevs guys!.

Using SQLJ in JSP files ... ?

Hi,
has anyone used oracle 8.1.5 SQLJ with JSP pages? In partucilar, with Apache Tomcat 3.0?
Help much appreciated, direct mails ([email protected]) preferred!
Cheers, all - keep up the good work!

Hi,
Yes, OJSP inside JDeveloper cannot currently handle the language="sqlj" extension. A workaround is to name your file Foo.sqljsp.
Before running the JSP on a webserver you will need to map the sqljsp extension to the class oracle.jsp.JspServlet, just as for OJSP setup, and then you can hit the page directly:
http://<host>:<port>/SQLJQuery.sqljsp
Let us know if you have problems..

Sqlj and jdbc for linux

Hi All,
I am currently set up the (tomcat) jsp engine on top of apache web server.
And now i would like to install both sqlj and a jdbc driver such
that I can query our oracle database. In all of the options for downloads
there is a windoze option and a solaris option. Do I have to wait for specific
"linux" version to get them to work. Or is the solaris option alright
for linux ??
slightly confused,
Chris

Unfortunately, this description is still rather unspecific.
It sounds, as if there might be an issue with the way database connections are established for the SQLJ and JDBC parts of your program. Could you provide more information on that, specifically on how you obtain JDBC connections and SQLJ connection contexts.

Jdeveloper, SQLJ and connection manager

Hello,
My question is wether it is possible (and if yes how), to use the connection manager within JSP and SQLJ pages, without using the Bussiness Components.
At this moment the sqlj or jsp program gives a class not found fault. I do not know how to get or where to find the connectionmanager class.

Yes it is possible. The connectionManager classes are in "connectionmanager.zip" in the /lib directory under where JDeveloper is installed. The library is "Connection Manager" within the JDeveloper IDE.
Hope this helps,

Ideas pls for a small application on java and jsp?

hi ,
I would like to create an application which for resume. I would like to codify the java code . The java code should be able to autogenerate jsp file's since the output of the resume would be on an jsp page. To add it simply a wizard for dynamic resume creation using java swings and jsp. Code for jsp should be autogenerated please note it.
Ideas please!
Thanks in advance

I'd like to add more information to Patreck's suggestion.
JSP pages are wonderful if you need the web server to perform some actions before sending you the final web page.
Here, you don't need the web server to do anything because your Swing application can do it for you. As Patreck implies, Swing can make a connection to the database, retrieve any information you want, perform whatever logic you need, and write the output to an HTML file.
To give you an example, you can use Internet Explorer to view a basic web page on your hard disk. You can also use Microsoft Word to view the same basic web page. They both do the same task and there is no need to force IE to use its Word plug-in in order to view the web page.
JSPs are not necessary because Swing will do all of the work for you. You only need JSPs if you want people to use your program through a web browser because they can't do Swing inside a web browser. You should only use one or the other, not both. Understand now?
If you really really must generate JSP code from a Swing application, then just write out the JSP stuff in the file. For example...
public void createWebPage( Printwriter pw, String myName ) {
   pw.println( "<% String myJSPName = \"" + myName + "\" %>" );
   pw.println( "<HTML>");
   pw.println( "<HEAD>");
   pw.println( "<TITLE>My Resume</TITLE>" );
   pw.println( "</HEAD>");
   pw.println( "<BODY>" );
   pw.println( "<H1>My name is " + myName + " and my JSP name is <%= myJSPName %></H1>" );
   pw.println( "</BODY>" );
   pw.println( "</HTML>" );
}As you can see, it's pointless to embed JSP when you can do all the programming within Swing first and just write out the correct response.

Cannot checkin/checkout html, js, txt, and jsp files in MS Sharepoint Workspace 2010

I am having issues checkin/checkout html, js and jsp files in Microsoft Sharepoint Workspace 2010. I can access (checkin/checkout) any files in the actual Sharepoint site, but when I am synchronized to the site in Sharepoint Workspace 2010 I cannot access
html, js, and jsp files. When I try to checkout a html file, a message pops up saying:
"Can not perform this operation. This document has been checked out or may no longer exist."
Could this be a synchronization issue, or was Sharepoint Workspace 2010 not design to work with html, js, txt, and jsp files?

Hi everyone,
Is there a good resource that explains how to build a forum using servlets and JSP technology?
Regards,

please let me know here if you find any useful resources...I am in the process of writing my own searchable threaded forum for my company with JSP's/servlets. It's a very slow process at the moment though...if I ever finish it, I'll gladly share it.

How to master good design with EJB and JSP?

I use JSP to calling EJB. But the .jsp file is complex and it's difficult to maintain...I just want to work higher efficent with EJB,JSP and JavaBean. I want to know is there a good design with EJB and JSP? and is there any good material about MVC for EJB,JSP and JavaBean?

You should read the J2EE blueprint available on this website. Better download the PDF, and print it for yourself so you can read it anytime.

WL vs. WL-express and JSP vs. javascript/SQL

folks-
i am trying to convince a certain party to
disband a web-based job tracking system being
written in ASP, javascript, html, css and SQL.
it will be hosted on MS webserver running NT.
i am trying to convince them to use JSP and
WL express. i have done two years of EJB
component work on weblogic, however, i have not
done work with JSP or thin-clients. i was mostly
business-logic.
anyway i have some questions and need some
direction. i already know JSP is better than
ASP/javascript etc. because:
* ASP is proprietary. ditto for VBscript
* with an IDE creating JSP is easy and JSP
automatically creates servlets which is way
faster than by hand
* JSP is JAVA based and hence benefits from
all the portability pluses of JAVA
but here are the more difficult questions:
* why is WL express better than an MS
web server? (not including WL market share
and size. after all MS can claim that)
* since WL express does not have an EJB
container, how do you access the database?
via JDBC? does one just have JDBC code
floating around?
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
* if a web app grows beyond JSP with WL express
into the need for an EJB container, i would
think that most of the app needs to re-written
as business-logic must be refactored into EJBs
and all JDBC code will be replaced by container
managed beans. this sounds a like a lot of
rework.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and
force across the network?
with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?

* since WL express does not have an EJB
container, how do you access the database?

Use JDO or an OR-mapper or embed JDBC into your own data access classes.
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
Presentation=JSP
Logic=Servlet
Data access=JDO or similar

You should be able to tell up front if it a tx-intensive app that requires
WLS.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and

They aren't exclusive. For dynamic pages, use Javascript on the front end,
JSP on the back.
* with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?
In the real world, and for most apps, while Java has the architectural edge,
they both have similar scalability and similar robustness. MS gives you no
choice though, and you rewrite every time they see a new buzzword. You can't
leave MS-land without abandoning almost everything. You can leave WLS in a
week if you have to.
It's an investment. Invest wisely.

Hot swap and JSP debugging for Weblogic in exploded format?

Hi,
I'm trying to use JDeveloper for JSF development to be deployed to a weblogic server.
I must say JDeveloper is a great tool for JSF development as none of the free IDE in the market can do what JDeveloper does.
However, I have a question on hot swap and JSP debugging.
I have managed to setup JDeveloper to debug my JSF application deploy to my Weblogic server's applications folder in exploded format.
I can step through the java code.
However, I didn't manage to do a hot swap and the break point set in the JSF-JSP does not seems to take effect.
I would appreciate any advice on the problem.
Thanks.
Han Ming

How did you setup the server to handle exploded format? Appreciate the help. Sorry can't help with your question though.
Thnx.

Servlet and JSP in OAS

I'm developing web application with OAS
4.0.8.1 and JDeveloper 3.0 and I want to call
JSP from servlet using "RequestDispatcher".
I downloaded JSP for OAS from www.olab.com.
In the Release note, there is a description
about RequestDispatcher, but I cannot
understand about details.
In what configuration can I use servlet and
JSP together with RequestDispatcher. Anyone
scceeded about that?

Javabeans and JSP

I am new to Beans and JSP. I would like to know how I can 'get' the resultset and output to a JSP? It would have a few records and each record will have field1,field2 and field3.
My question again: How to continue from here in Beans? How to write the code in JSP? Can anyone guide me with some simple codes as I would not be able to understand advance codes.
Thanks.
public String Login(String inputDep) throws SQLException
          String returnString = null;
          String dbUserid = "sa"; // Your Database user id
          String dbPassword = "" ; // Your Database password
          try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               Connection con = DriverManager.getConnection("jdbc:odbc:test", dbUserid ,dbPassword);
               Statement stmt = con.createStatement();
               String sql= "select * from Product where dept = '"+inputDep+"'";
               ResultSet rs = stmt.executeQuery(sql);

You could also try to read the resultset in your bean.
like:
=========== Bean ===============
public class myClass
public AccountData Login(String name, String password)
AccountData data = new AccountData ();
data.setName (resultset.getString ("name"));
//other setter methods
return data;
// use inner class to store values
public class AccountData
    AccountData ()
    private String name = null;
    //further attributes
    pubilic String getName ()
        return name;
    void setName (String name)
        this.name = name;
    //further getter and setter
}=========== JSP ===============
<jsp:useBean id="myBean" scope="session" class="classes.BeanClass"/>
<% MyClass.AccountData data = myBean.Login (name, password); %>
Name : <%= data.getName () %>Note > means %>

FLEX and JSP

so for my senior design project i designed a web project using java servlets and JSP pages. For one part of the project to visualize some data i used FLEX to create GANTT Charts. Now that it's done i was looking into how to embed that flex code into JSP page and i found on ADOBE website links for taglibs, however right now it redirects me into a page of Adobe LiveCycle , which cost a lot of money.
Is there another way to embed flex into jsp? or some other way to get just the taglib for flex?
Thank You

It depends on how Flex is getting the data, and how it's generated. If you refresh the page, then the Flex app will be reset, and won't have any knowledge of previous data. One thing you could do is store the data on the server and access it via some web-service calls (eg AMF or REST). The server could manage the user's session, store data, and generate or retrieve previous data.
