I have tried all possible configurations of classpath with mysqlconnectorj and Tomcat, but i could not find any solution. Plz help urgently. Thankz a lot.

Your DB connection is probably failing
As a result your result set "rs" is null when you get to it later on, causing a null pointer exception.
Do you need to provide a username/password for your database?
Have you configured your database to allow connections from localhost?
If you haven't already figured it out, doing SQL programming in a JSP is bad practice. Put your SQL code into a java bean / class where it belongs.

Java Server Page

Good Day, Gentleman and Ladies
I need help in Java Server Pages (JSP)
I using Weblogic 6.1 as Development Environment.
Developing in Macromedia Dreamweaver 4.
When I preview using Dreamweaver, It can be display properly.
But when viewing in Internet Explorer, it give following error
unreachable statement - out.print("\r\n\t\t\t
uses or override a deprecated API.
Following is the statement in JSP Code
<input name="<%=ParamName%>" type="text" value="" size="8">
<a href = "javascript:show_calendar('parameterInputForm.<%=ParamName%>');"><img src="images/toolbar/calendar.gif" border=0 alt="Click to see calendar" align="abmiddle"></a>
Could any kind souls please help me in it.
Thank you very much, your help is deeply appreciated
Luo_Sha_Zong_Zu

Hi
First, dont put msg with subjects like "Java Server Page". Put msg with subject showing the problem, like "unreachable statement - out.print("\r\n\t\t\t uses or override a deprecated API"
Your problem is with the value of the var "ParamName". It has something with "return" and "tab". Check it

Using Java Beans in Java Server Pages

Can we not use a method of Java Bean in a Java Server Page ?
I am trying to retrieve the user email from a java bean method "getUserEmail". I am instantiating the class, but when I try to use that in JSP tags, I am getting an error.
<jsp:useBean class = "formjavabean.application" id = "applicationId" scope = "session" />
<%@ page import="java.io.*, java.lang.*" %>
<%!
String user = applicationId.getUserEmail() ;
String f3 = "ftn03" ;
String f3not = "ftn03 file not uploaded";
...........I am failing in debugging that, can anyone help plz ?

Here is my whole code in parts:
First the head section:
<head>
<title> Fastran </title>
<jsp:useBean class = "formjavabean.application" id = "applicationId" scope = "session" />
</head>JSP part in the body section :
<%@ page import="java.lang.*, java.io.*" %>
<%!
private String f3 = "ftn03";
private String f3not = "ftn03 file not uploaded";
private String f7 = "ftn07";
private String f7not = "ftn07 file not uploaded";
private String f9 = "ftn09";
private String f9not = "ftn09 file not uploaded";
public String checkFile3()
    File ch3 = new File("C:\\JBoss\\jboss-4.0.5.GA\\bin\\Fastran\\ftn03") ;
    if (ch3.exists() == true)
        return f3 ;
    else
        return f3not ;
public String checkFile7()
    File ch7 = new File("C:\\JBoss\\jboss-4.0.5.GA\\bin\\Fastran\\ftn07") ;
    if (ch7.exists() == true)
        return f7 ;
    else
        return f7not ;
public String checkFile9()
    File ch9 = new File("C:\\JBoss\\jboss-4.0.5.GA\\bin\\Fastran\\ftn09") ;
    if (ch9.exists() == true)
        return f9 ;
    else
        return f9not ;
%>Java Script in the body section, using methods defined in the JSP part:
<script type="text/javascript">
        function validate_file ( )
                var file3 = "<%= checkFile3() %>" ;
                var file7 = "<%= checkFile7() %>" ;
                var file9 = "<%= checkFile9() %>" ;
                if ( file3 != "ftn03" || file7 != "ftn07" || file9 != "ftn09" )
                    alert("Please upload the required file") ;
                    return ("fastran.jsp") ;
                else
                    return ("processForm.jsp") ;
        function validate_upload ( )
                valid = true;
                if ( document.val_file.filefield.value == "")
                        alert("Please select a file for upload") ;
                        valid = false;
                return valid;
    </script>Finally the form and button part of the page, in the body section:
<form name = "val_file" method="post" action="upload.jsp" name="submit" enctype="multipart/form-data" onSubmit = "return validate_upload();">
Upload Files: <input type="file" name="filefield" >&nbsp&nbsp<input type="submit" name="submit" value="Upload"><br>
<font color = "Red"><h5>(ftn03,ftn07, and ftn09)</h5></font><br><br><br>
Files on the server :<br><br>
<font color = "Green"><h5>
<%= checkFile3() %><br>
<%= checkFile7() %><br>
<%= checkFile9() %><br>
</h5></font>
<br><br><br><br><br><br><br><br><br>
<input type=button onClick="location.href='logintest.jsp'" value='Home'> <input type=button onClick="location.href=validate_file()" value='Proceed' ><br>
</form>Now try this:
Change <%! to <%, or try using bean method as:
String userEmail = applicationId.getUserEmail() ;..........and that is my problem. I would really appreciate any help, thanks

Displaying a picture or image in a java server page

I am using tomcat to load my java server pages. I need to display a picture in the page. Can somebody help?

The images are not located on my site, or computer, but rather they are located on different websites. This is what the browser recieves when the jsp runs:
<IMG SRC="http://www.thesite.com/images/theimage.gif"/>
and the site that is running the JSP is:
www.mysite.com/jsp/PicPage.jsp
Is this what you think maybe happening when the browser tries to process the linked image:
www.mysite.com/images/theimage.gif
I don't really understand the nuances of HTML, but if I specify a web address completely in the HTML then wouldn't that specified website be queried for the pictures by the web browser?
Thank you for any help you can provide.

How do I set a breakpoint in a Java Server page (.jsp)?

I have set up an application for remote debugging and am able to connect to it from JDeveloper. When the code execution comes to breakpoints that I have set in java (.java) files they work and the application stops so I can debug etc.
This also applies to breakpoints set in java code that is called from Java Server pages.
However if I set breakpoints directly in a java server page whether it is in html code or in java code (such as scriplets) the execution does not stop and the breakpoints are ignored.
Why? Is there some extra thing I have to do? I have tried in Project Properties/Run/Debug/Profile/Edit/Launch Settings to choose server as Virtual Machine for instance but that does not change anything.
Comment. I do not know if this is of interest but I am going to add some java server pages to an application and they are defined in a directory like this:
. . . src\org\yawlfoundation\yawl\resourcing\jsf\jsp
but when the tomcat deploys the .war file they end up here:
. . . apache-tomcat-6.0.18\webapps\resourceService
As I can find no package declaration in a .jsp file this should not matter but I mention it anyway.

Hi user10477024,
thanks for explaining your background on what you are trying to do and I do understand the approach you are taking. Unlike user10689900's completely random post.
I've tried to convey why there is no support for JSP debugging in JDev, but again the main reason is that the current frameworks do not code Java directly into a JSP. The JSP is purely used to position the components on the page aiding visual design and real Java classes in tag libs do the rest.
So the evolution has been:
Servlets (Java classes writing HTML logic and intermingling presentation and business logic)
JSP 1.0 JSP (HTML looking) files where you can add scriptlets enclosed in <% ... %> <- you are here
JSP 1.1 Introduction of Tags and Tag libraries, tag libraries are true java classes and the JSP controls layout and simpler more elegant design.
Really JSP 1.1 is all about building reusable components together in tag libraries that can be reused across pages and improving design by not mixing presentation and business logic code together.
If I had inherited something as you have, my advice (if you can) would be to code up some tag libraries because it would be a good learning experience and would be very helpful for moving to more advanced frameworks like JSF.
regards,
Brenden

Integration of PL/SQL and JSP (Java Server Pages)

I need to match a web application developed with PL/SQL with another developed in JSP (Java Server Pages) the problem is that the two apps interact with the same databese, an share de same users, I need to know how to get the user and password loged into pl/sql when the user want to use same of de .jsp pages running on another application server?

Hi Michael Vstling,
Did you try the java classes library (SDOAPI) that can be downloaded from OTN?
It may provide you with a better alternative when manipulating geometries in the Java space. There is an adapter in SDOAPI which can convert a JDBC STRUCT object into Java Geometry object defined in SDOAPI, and vice versa.
There are at least two ways in mixing PL/SQL and Java. The first one, as you mentioned, is to define your custom function in terms of PL/SQL and call it from within your Java program. With SDOAPI, you have the second option, which is to define your own functions in Java using SDOAPI and deploy them as Java stored procedures in db. You can then call them from within your PL/SQL code. In either way performance depends on a lot of things and generally it requires a "try and improve" approach.
About JPublisher and sdo_ordinate_array it may not be a spatial related problem. Did you try search the Java-related forums first?

Books Java Server Pages. I would like to learn

I have been using PHP for the last 4 years, but would love to learn Java Server Pages, .jsp Can anyone recommend good books that can teach me the basics of .jsp so that I can start creating webpages with webforms etc....
I see .jsp as a logical progression.

Hi,
You will get lot of books on JSP written by some of the best brains in Java / J2EE. However, there is nothing that substitues exposure / experience.
I would suggest that you use Google & check out some of the web sites that offer helps for beginners in JSP. You can also download OC4J, develop your JSPs & start playing with it.
And, if you have any problems, the forums are always there...:)

Sandeep

Java server pages+ database

res sir,
I want to ask you a qestion regarding a java server page sir pls. can you tell me the answer of my question. i will be pleased to know about my answer.
Q1:- Can Java Server Pages help to communicate With Databaseand Can I put any informatin in databse through JSP?

yes jsp pages can communicate with databases, done with jdbc. people use it all the time, like in a login page, you can connect to a database and check the user and password before allowing the user into your site.

WHAT ARE JAVA SERVER PAGES?

Right now I am learning java on my own, and I have a question.
What are Java Server Pages(JSP)?
Thanks

In short, they're standard HTML pages with embedded Java code to dynamically create pages based on values from the user, a database, or some other source. Search the java.sun.com site for a more detailed explanation, and examples too. Or, pick up a book.

Hi Saru,
It seems u dont have the correct sdm password or someone has changed the sdm password.It has not accepted the credentials u have given during deployment.
Check with all Sap enterprise portal settings in the prefernces/NWDS
The host name,alias,port
If not done with
Try to change the sdm password using this Password trouble in SDM
restart server again after changes
even try
- Stop nd restart the sdm from yor NWDS and deploy once again
