JDeveloper 3.1 and JSP problems

Hello everybody.
I present myself. I am a French student in computer sciences who makes a training course in a French company. (You will excuse the bad quality of my English)
I have some difficulties in the use of Oracle JDeveloper tool.
1st problem:
I encountered this problem during the creation of a JSP page for a simple Intranet application connected to an Oracle database.
JDeveloper doesnt want to take into account the fact that one of my tables has two primary (composite) keys;(Each of these two keys is primary key of another table). That results on the one hand in an error during the loading of the default edition form (" JBO-25030: Failed to find or invalidate owning entity ") and in addition by impossibility of consulting the recordings of this table according to one of the two key parameters (selected in RowSetBrowser). Nevertheless, this last aspect works within the Oracle Business Component Browser.
2nd problem:
Imagine, for example, the following simplified conceptual diagram:
Racks ---> Files ---> Sheets (they are tables)
How on a JSP page, can I display in the easiest way (with a JSNavigatorTab and a RowSetBrowser), the recordings of the table Sheets of a particular File, without to use a selection at the table Racks level.
(You choose directly, with a ComboBox or a RowSetBrowser, a File to display all the corresponding Sheets, without to choose a Rack before.)
In fact, I try to have an application as simple and ergonomic as possible.
I thank all those who will be able to inform me on these obscure points which slow down my project considerably.
Regards.

Hi,
* For your 1st problem, try to uncheck the "composite association" checkbox in the association object linking your tables together, should work better.
* For the second one,
when you create the application module containing the rack/file and sheet views, add the file view at root level (i.e do not use the view link relationship, which would include it as a detail view for the racks view), then add the sheet view through the file/sheet viewLink.
This way you'll be able to browse the entire file and sheet list in a basic master/detail view.
Good luck, Remi

Taglib and JSP problem

Hi!
I cannot determine why I'm getting the following error:
I've installed Apache Tomcat/4.0.6
"PARSE error at line 6 column 19
org.xml.sax.SAXParseException: Element type "taglib" must be declared."
Can you tell why the parser does not recognize it?
Appreciate any help.

this is a wild guess, but make sure the taglib text you added to your web.xml doens't contain funky characters you may have copied from some web page. i.e. retype it by hand if you copied it.
If that isn't it.. sorry i don't see a problem.

Struts and JSP problem..help needed

Hi,
I am trying to use request.setParameter("formatName") from the JSP page into the ACtion class to display the user entered values.
I have my struts action classes tagged to be in session scope since the UI is a wizard and i want the values to be carried on until they click finish. on the wizard.
I want the formatName floating across the wizard, I have another value called."Category" floating since its a dynamically generated variable using the formbean.

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.

Jsp and JPanel problem

Hello. I've been to this forum many times, but have always been a bit gunshy about posting anything of my own. Now I have a problem I haven't seen before, so here goes. I have a JPanel in a java program that has all sorts of other componants added to it. I am trying to display the whole thing in a jsp page. This is what I am doing in the java file to return the image ("display" is the JPanel):
public byte[] getImage(){
    int w = display.getWidth();
    int h = display.getHeight();
    BufferedImage img = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
    display.paint(img.createGraphics());
    ByteArrayOutputStream os = new ByteArrayOutputStream();
    ImageIO.write(img, "jpeg", os);
    return os.toByteArray();
}and then in the jsp page I say:
<%@ page contentType="image/jpeg" %>
<%@ page import="myPackage.MyClass" %>
<%
     MyClass picture = new MyClass();
     byte[] b = picture.getImage();
     OutputStream os;
     os = response.getOutputStream();
     os.write(b);
     os.flush();
%>And the problem is that the page is displaying a blank JPanel and none of the componants that were added to it. If I save the the JPanel as a jpeg in the java program, though, it does contain all the componants, so I am not sure what I am doing wrong here. If there is some way to get the all the JPanel componants returned, that would be great to know. Thanks for any help.

nope, that didn't work.
Maybe I am going about solving the problem all wrong. The JPanel and its componants are kind of like a template. When a user of the system submits their information it automatically puts the data into the template and displays it on screen as a jpg. It works when I save the jpg as a file from the java program but not when i send the byte array to the jsp server. It just shows the blank panel....
Is there a better way to go about doing this?

JSP and Tomcat Problem

Folks,
My apologies if this is off-topic for this forum, but I've been having this problem using Tomcat and JSP. I'm fairly new to Java.
Basically, I'm writing a webapp that uses servlets and JSP together. The servlet and backend classes all compile fine. Now, basic frontend page is called Console.jsp, and one of the commands that it runs is <%@ page import="DJUser">
Here's the problem: Console.jsp is in $CATALINA_HOME/webapp/
DJUser (and the rest of the classes I'm using) are in $CATALINA_HOME/webapp/WEB-INF/classes
When I attempt to run Console.jsp I get this error:
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
The import DJUser cannot be resolved
An error occurred at line: 9 in the jsp file: /Console.jsp

I'm running Tomcat 5.5.12 on Mac OS X 10.4. Could this be a permissions issue somehow? For right now (testing purposes only) I have tomcat running under my (non root) account.
I've been scouring the web for a while, and I can't really find anything on this. I'd appreciate any help you could give me.
Thanks!
Dylan

Put the DJUser java file in a package (say com.myClasses) and recompile. Then put the DJUser class file under the WEB-INF/classes directory in the proper package structure (WEB-INF/classes/com/myClasses/DJUser). Stop and restart the server to pick up the new classes. Make sure to change the jsp import statement ( <%@ page import="com.myClasses.DJUser">)

Upgrading JDeveloper 9052 to 1012 and centrino problems?

I have recently purchased a new laptop with the following specification:
Dell 9300
Centrino 1.8
1Gb DDR2
ATI x300 128Mb
60Gb Hard Drive
Windows XP SP2 + all updates
to replace my previous development machine.
I have experienced the following problems when running JDeveloper on it and I'd appreciate your assistance in rectifying them.
1. I installed JDeveloper 9052 on my laptop and tried to run an ADF based application that I have got running on many other development machines and a 904 server. When I ran the application on my laptop it worked fine until it reached the point within the application that created an inputStream from a URL - where it failed. I know that it fails exactly at this point after spending some time debugging the code. I found this very strange as I could successfully view the content of the URL in a web browser.
2. In an attempt to find a solution to point 1. (see above) I installed version 1012 of JDeveloper. I tried to open the existing project that I had created in 9052 and when prompted agreed to convert it to the new format. Then without opening or editing any of the files I successfully ran the applicaiton by right clicking on the view controller within the project (applicaiton navigator panel) and selecting run from the context menu. The application ran successfully without any problems at this stage.
HOWEVER, I then opened up the struts-config pageflow diagram and tried running it from there, the project failed.
After studying the struts-config file both before and after I had opened it within 1012 I found the following discrepancy:
BEFORE: - - - - -
<action path="/getParams" className="oracle.adf.controller.struts.actions.DataActionMapping" type="view.GetParamsAction" name="DataForm">
AFTER: - - - - -
<action path="/getParams" className="oracle.adf.controller.struts.actions.DataActionMapping" type="view.GetParamsAction" name="DataForm" parameter="unknown">
After manually removing this line of code I was able to get the application to run again. However every time I edit/view the struts config file or indeed save changes and reboot JDeveloper the parameter="unknown" line is added again and prevents the project from running.
3. After further investigative work following point 2. I came across what I believe to be a further bug.
When I reopened JDeveloper I noticed that the struts-config pageflow diagram had changed. A dataAction had been replaced by a dataPage as well as the extra line of code being added as described in point 2. The pageflow diagram should be dataPage --> dataAction --> dataPage but now it was dataPage --> dataPage --> dataPage.
After further investigation I found a descrepancy in the following file before and after I had opened it in 1012. The nominalHeaderXml4\ViewController\model\StrutsPageFlow.oxd_struts file changed from this ....
<shape name="/getParams">
<elemRef name="" value="3d2b2d0e-0104-1000-8008-c222e564ea8e::/getParams::StrutsDataAction" type="StrutsDataAction" class="o:b:CID"/>
</shape>
to this when I had opened it 1012.
<shape name="/getParams">
<elemRef name="" value="51d65a60-0104-1000-8003-c222e56470a8::/getParams::StrutsDataForwardAction" type="StrutsDataForwardAction" class="o:b:CID"/>
</shape>
I have speant the last 2 days looking into these problems. I have found that both points 2 and 3 happen consistantly when opening 9052 projects in the 1012 environment. And have elimated the following things when trying to get JDeveloper 9052 to work correctly, firewalls, antivirus, windows updates, and software conflicts. The only difference that I can identify is that my new machine uses a centrino chip and my old one used a P4.
I hope that someone will be able to shed some light on these problems for me as soon as possible. Thanks in advance for your help.

The struts-related observation is noted in the JDeveloper 10.1.2 Release Note Addendum:
http://www.oracle.com/technology/products/jdev/htdocs/10.1.2.0.0/readme_10.1.2.0.0_addendum.html#jan1
For the 1st issue, I'd recommend opening a TAR with metalink so our worldwide support engineers can help diagnose the problem. I've not heard of any Centrino specific issues to date.

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.

JDeveloper 10g: Preserving Translated JSP when making?

Hello,
Can anyone tell me how to get JDeveloper 10g to preserve JSP page translations (in the \classes\.jsps\ folder) when there is an error in the compile of the generated servlet?
I am new to JSP development and I am getting an error when making a JSP page that says that the request and session variables are not available when using something like:
<%! String var=(String) session.getAttribute("someAttribute"); %>
I have not dissabled sessions using a page directive.
I am hoping that I will gain a lot more insight by looking at the generated servlet code.
Thank you,
Rich

Hi, the compilation of the JSPs before building the WAR file is a there to help you finding problems/errors before deployment. You should take them serious and resolve them before the deployment.
What kind of errors do you get?

JDeveloper 10.1.3 encoding problem

Hi,
I'm from Brazil and while testing the new JDeveloper 10.1.3, this problem occurred when i started migration from JDeveloper 10.1.2.
All my JSPs suddenly became strange, with weird characters, where supposed to be special characters, (like accents). I'm using encoding default on JDev(10.1.2), which was CP1252, in the version 10.1.3 the java classes are ok, but the jsp not. I already tried modifying the encoding options of the JDev but none work. The only solution i found is to open all the JSPs and replace those characters, this way JDev recognize them, which i insist are ok in other tools. Only in 10.1.3 i found these problems. In the help i found something related to the encoding of the files, which must be preserved, but it was pointless since i couldn't find any options for doing such thing
thanks in advance

Just one more statement to the thread since I am having similar trouble with greek encoding on Linux.
First of all I think that it makes no difference how much you tamper with the environment --> encoding setting in JDev. In my case all parameters had the same value but the JSP text appeared mangled.
As far as I have tested I found out that the only safe way to migrate JSP's from pervious versions of JDeveloper is
a) Use a different editor (Kate from Linux KDE is just perfect) to verify that the encoding of the file is correct. In my case that would be Greek iso8859-7)
b) Modify the JSP so that the first line looks like <%@ page contentType="text/html;charset=iso8859-7" %>
c) Save the file making sure that it gets the right encoding.
After that the file may be opened and modified correctly in the JDeveloper editor. I have found that was to only way to make DataEditComponent.jsp pages created with JDev 9i for BC4J projects run on 10.1.3
The funny thing is that if you look at the property inspector, it still says that loadEncoding and saveEncoding have a value of UTF-8, which is probably false but ....

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?

I found a white paper 408newfead.pdf, that says under "Future

support
JSPs. I don't know if this release is out yet.
I wish Oracle would get with the times and put out a product that
is consistent with the technology they are touting as the
future.
Having us download Suns server to run servlets and JSP is
ridiculous for the worlds second largest software company!

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!
Regards,
Simon
