JDeveloper and JSP

I am a new person to JDeveloper technology.
I wanted to know that if I create JSP using JDeveloper 3.0, and then upload the JSP pages on a UNIX server, will I need application server.
What is JServer ?

Anny,
You can developer Java Server Pages using JDeveloper and deploy them to any platform.
If your deployment platform is UNIX, you will need an application server that supports the Servlet API. Apache plus Tomcat is a good option. You can learn more about it at www.apache.org.
JServer is the VM that runs inside the Oracle8i database. You can learn more about it on the Oracle8i page of OTN.

JDeveloper and JSP 1.1

Hallo,
I'm using JDeveloper 3.1 for my JSP projects.
This version of the product was deployed with OracleJSP (ojsp.jar) version 1.0.
Now, I have the need to use some JSP 1.1 feature, but I have found no hints (Technet, Metalink) to upgrade OracleJSP at version 1.1. I downloaded 3.1.1.2, but this version have not JSP 1.1 support,too.
I discovered that iAS 1.0.1 I downloaded and tried is deployed with OracleJSP 1.1.
I copied libraries ojsp.jar and ojsputil.jar from iAS to JDeveloper\lib (before I backuped my original ojsp.jar).
I tried with a simple JSP test application and all seemed ok.
But, when I tried with a production application I had this problem: some pages weren't compiled with this error:
"JDeveloper could not insert new character. 1024 line limit exceeded"
Apparently my jsp pages seemed to be syntattically correct. Also, there was a page with .jsp suffix, but integrally composed of HTML (no scriptlet).
Well I checked the .java generated from jsp and I discovered than OracleJSP 1.1 compiler has a different behaviour from the same one in release 1.0.
Pratically, OracleJSP 1.0 compiler generate an istruction out.println("...") for every text line in a JSP page.
OracleJSP 1.1 compiler generates an entry in an array char text[][] for every block in a JSP page, where a block is a sequence of istructions separated by scriptlet marks (<%...%>).
Then for every block there is a corresponding out.print(...).
What happens ? It's simple. If I have a flat HTML jsp page, I have only a "one line structure" text[0] and if all text is greater than 1024 characters, JDeveloper generate a compile error.
The same happens if I have blocks of text or scriplets greater than 1024 chars.
A simple workaround is to insert an empty scriptlet block <% %> between blocks too long, but I don't like this!
Well, could anyone help me ?
Is there an official Oracle upgrade to JDeveloper, so I could use JSP1.1 features ?
Thanks.

from a sept 14th posting by the jdev team ...
Hi,
This is a good question that you ask and I am glad to say that JDeveloper 3.2 which should be available sometime in November, will be fully J2EE compliant in that we will support JSP 1.1 (with taglibs), Servlet 2.2 and EJB 1.1.
Thanks,

Import statement in .java files and .jsp files

Guys I have few mysteries about this import statement.
Please correct me if I am wrong.
1)Suppose if I have a folder c:\SourceFolder it has one.java and two.java files.If I compile one.java then one.class files is created in c:\ClassFolder .Now two.java uses one of the method of one.java,and without using import statement I am able to compile two.java, and two.class file is created in c:\ClassFolder.I assume that the path of one.class was taken from the CLASSPATH environment variable,hence I there was no need for import statement .........am i right ?
BUT... in My.jsp,which is in C:\JspFolder, if I want to use one.class,then I have to specifically import the class I want to use.That is i have to say
<%@page import="one"%>
and since the classpath is C:\ClassFolder ,it finds one.class in the C:\ClassFolder.(Note that My.class is created in a folder different from c:\ClassFolder )
But I am wondering why was there no need for me to import one.class in two.java.
(Note I am using JDeveloper and Apache server)
Please help.
In this case the pSo I am wondering in JSP why it doesn't take the class I am looking for from the classpath .
Help.

You have to understand Java scoping rules. In the 1st scenario with the two Java files I am guessing neither one of them begins with a package statement. This means that they belong to the default package. When you compile the compiler uses the classpath to resolve method calls looking in the default package since there was no import statement specified in two.java. JSP is a little different. Now I just read this here in these forums a couple of days ago. Since the classfiles generated from the JSP files are not in the CLASSPATH they are loaded by a different classloader. This is why you have to import all references to all classes in the default package.

(Note I am using JDeveloper and Apache server)
Please help.

It has to do with packages. Most java classes are in a package, the name of which must conform to its place on the filesystem relative to the classpath. By that I mean that if you have com.mystuff.One.java, it must be in a folder com/mystuff where com is located somewhere in the classpath.
What you've done is a little different. I'm assuming a couple of things:
1. you have no package declaration at the top of one.java or two.java
2. you have the current directory "." in your classpath.
Java has the concept of the "default package", which covers classes without a declared package, and in your case is the current directory.
So when you're in c:\sourcefolder and run the compiler, then "."="c:\sourcefolder", and that directory is part of the default package. No import statements are necessary for classes that are in the same package. This is why two.java can call methods in one.java without an import statement.
When you run your jsp, the "current directory" part of your classpath is not c:\sourcefolder, but some other value (probably the directory you start your jsp engine from) You will have to import all non-java-library classes because the jsp itself becomes a java class, with a package that is determined by the jsp engine.

HELP: include another page in with JDeveloper and ADF

Hi all,
I am trying to make a layout page with JDeveloper and ADF. But I just can't make things work. I have the pre-coded header and footer html pages and want to include them in a jspx somehow. I tried panelPage too, but the rendering style is away from our pre-coded header and footer.
1. Use jsp:include.
header works fine but footer is rendered before the page content, even if the footer is placed after the page content. Is there a way to customize the position?
<f:facet name="footerFacet">
<f:subview id="footerView"
binding="#{backing_welcomePage.footerView}">
<jsp:include page="/footer.jspf"/>
</f:subview>
</f:facet>
2. Use frameBorderLayout.
I followed the doc and use the document tag. But the frame page is rendered but none of included pages are rendered. So I got a blank page.

<f:view>
<afh:html>
<afh:head title="my frame page">
<meta http-equiv="Content-Type"
content="text/html; charset=windows-1252"/>
</afh:head>
<afh:body>
<afh:frameBorderLayout height="100%" width="100%">
<f:facet name="center">
<afh:frame source="topPage.jspx" name="topPage3"/>
</f:facet>
<f:facet name="top">
<afh:frame source="topPage.jspx" height="200" name="topPage2"/>
</f:facet>
<f:facet name="bottom">
<afh:frame source="topPage.jspx" height="200" name="topPage1"/>
</f:facet>
</afh:frameBorderLayout>
</afh:body>
</afh:html>
</f:view>

<f:view>
<af:document title="FrameBorderLayout Demo">
<af:form>
<af:panelGroup layout="vertical">
<f:facet name="separator">
<af:objectSeparator />
</f:facet>
<af:outputFormatted styleUsage="instruction" value="<b>A frameBorderLayout</b>"/>
</af:panelGroup>
</af:form>
</af:document>
</f:view>

for #1 have you tried throwing a verbatim tag around your includes like:
<f:verbatim>
<jsp:directive.include file="/includes/footer.jsp"/>
</f:verbatim>
it's how we got around intermixing html and jsf

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?

Are Oracle Java Serlet and JSP samples working in Oracle9i?

Oracle web site provides many good Servlet and JSP samples. All
the instructions talk about Oracle8i. Does anybody know for sure
they are working under Oracle9i or not?
Thanks!
H.

OTN has sample applications that demonstrate a range of JSP techniques, from basic to advanced. OTN provides two versions of the samples: one version is built to the Servlet 2.0 specification and runs under Oracle9iAS-JServ or JDeveloper, the other verion is built to the Servlet 2.2 specification and runs under the Oracle Servlet Engine (OSE) built into the Oracle8i database or the mod_ose module of Oracle9iAS.

InterMedia Java Classes for Servlets and JSPs and Netscape

I am using the interMedia Java Classes for Servlets and JSPs to upload and retrieve multimedia data. I have found that it is much more performant in Internet Explorer (5.5) than in Netscape Communicator (4.7). In fact, I cannot upload images larger than 10K at all using netscape. However, the same image can be uploaded into the same application using IE. Is this a known issue?
Thanks in advance.

Hi,
We have successfully uploaded multimedia data in the giga-byte range (Quicktime and AVI files) at the same speed with both the Netscape (4.7n) and MS IE (4.n and 5.n) browsers. One thing we have noticed is that its very important to set the manual proxy settings correctly if you have an environment with a proxy server. If you don't, then uploads can go via the proxy server and, for some reason, that seems to take considerably longer. For example, suppose you are in the www.xyzco.com domain and are connecting to a host named webserver.www.xyzco.com, then specify webserver and webserver.www.xyzco.com (to cover both cases) in the "Do not use proxy servers for..." box in the manual proxy server configuration screen. Also, if you're using a tool such as JDeveloper that uses the host IP address in the debugger environment, then you also need to add the numeric-based (nnn.nnn.nnn.nnn) IP address to this list.
Hope this helps.
In order to better understand the variety of ways in which our customers are using interMedia, we'd be very interested in knowing a little more about your application, the interMedia functionality that you are using, and how you are developing and deploying your application. If you are able to help us, please send a short email message with some information about your application, together with any comments you may have, to the Oracle interMedia Product Manager, Joe Mauro, at [email protected] Thank you!

JDeveloper and CVS and TeamWork

Hi,
we have a small team with 4 members and are developing in JDeveloper 10.1.2 with CVS plug-in (struts, toplink, jsp).
We are beginners and are frustrated now: every commit/update causes problems.
Always are problems with
- project.jpr files (synchronization among developers)
- sessions.xml (we cannot really add this file to cvs)
- state of offline tables (and digrams) are sometimes wrong show: restart of JDeveloper is necessary
- many JDevelopers files are unvisible, but must be added to cvs
- and more and more
Please - are somebody using JDeveloper & CVS in team with satisfaction? Are our problems beginner-problems or is this way wrong?
Thanks for your experience.
Jara

My biggests issues with JDeveloper and CVS are as follows:
1. Oracle puts out an article that talks about Version controllable XML and the biggest culprits of violators of this rule are the Oracle project files: StrutsPAgeFlow.oxd_struts, ViewController.jpr, and Model.jpr. Not nice when you can no longer open your Struts-config.xml file due to all the <==== lines in the file! In almost all instances, since we've built most of the files and aren't adding/removing much from the project as a whole, we can easily correct these problems then commit again, or just issue a clean update on them, and disregard (especially when it appears to be an ordering issue)
2. Also, we've seen model.jpr files switch contents (areas look like they are swapped around) in between versions. Why? The files are identical except the position of the nodes.
3. I really want to know my OUT-OF-SYNC files BEFORE I do an update. Kind of like the Uncommitted files window, I'd like: Hey, how out of sync am I?
4. The COMPARE utility is very nice, however, once CVS takes over and does the automatic MERGE, you're really left with a mess (at times). Any time we get a "failure to update" message, we issue a compare against the current reposistory version verses version on disk and see what the differences are. Then we search for whether our stuff was merged properly.
5. The only docs I've seen on Jdeveloper and CVS are "introductory" type documentation. Don't put out a document that talks about issues that are "out-of-scope" when these are the very issues that people need to deal with every day, and are looking for answers. The "oracle jdeveloper 10g" handbook is no better, offering about 4 pages of an "overview of CVS".
6. People have asked before about CVS, even on Metalink and an answer from Oracle is to look at an OTN post. I'm sorry, but that really doesn't cut it, especially when your support bill is over $500K/year.
enough rambling...
CVS and Jdeveloper 10.1.2 are working at our shop with 3-4 developers on the project, but it can be paintful during the "conflicts during merge" times.

Timesten with JDeveloper and ADF

Hello,
I'm using Timesten with Jdeveloper and ADF and have noticed some problems which I allready posted in the JDevloper Forum:
Re: ADF TimesTen
These problems arise from using Identifiers with reserved words, which is not forbidden with Ora DB.
The settings in Jdev are to generate SQL92 conform code. This is the only way it works.
I'm wondering if there is a setting to make TT behave syntactical 1:1 like a Ora DB.
I even tried to change the Type Mode to Oracle and restarting TT but this doesn't help eighter.
Maybe someone of the TT pro's has a solution for this? TT is used as a cache in front of an Ora DB so it should understand the Ora Syntax ??
Thanks

Difference between facelets and jsp xml in Document Type

I want difference between facelets and jsp in Document Type in JDeveloper 11gR2 (11.1.2)
Thanks
Edited by: Amr Ahmed on Jun 8, 2011 7:46 AM

Let's see.
Facelets creates a facelets page
JSP creates a JSP page
{noformat}:){noformat}
Facelets is the "official" view language for JSF 2.0
http://www.realdevelopers.com/blog/development/facelets-vs-jsp should give you some more insight as well.

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.
