Develope complex WebService with JDeveloper and deploy to tomcat

Hello,
I am thinking of developing a complex WebService with JDeveloper and deploy it to tomcat.
The WebService should retrieve a few "normal" datatypes and a pdf and a few images. I try to store the pdf and the image in an Oracle DB as BLOB.
My idea ist to create a Package which selects the values, pdf and the image and retrieve them as the output paramter.
Then I want to create a WebService with the JDeveloper which calls this Package. This WebService should be published on a Tomcat.
My first question is if that is possible?
I think there are few problems.
I searched the forum about deploying a JDeveloper WebService to Tomcat, but I can not find a whole solution which is going to work. I read something about JAX-RPC, but I am new to this topic. So it would be very nice, if anyone could tell me where I can find the solution or post a quick guide to solve that.
Another question is how I have to decode the images and the pdf to provide those files in a WebService?
I would be very glad if anyone can help me or tell me where I can find information about that, becaus I am new to this topic!
Thank you,
Tim

Hi,
does anybody have an idea about that?
Thanks,
Tim

Webservices with Jdeveloper and Omni Porlet

I am trying to make a portlet that can read xml from a webservice
I first pull the webservice from the server....
<env:Body xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<ns0:getPreviousChargesDataStringResponse xmlns:ns0="http://assessment/" env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<rowset><row><Assessment_Group> etc...
</return>
</ns0:getPreviousChargesDataStringResponse>
</env:Body>
then I use the xsl to make it in the <rowset><row> form.
My xsl translation looks like this...
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:value-of select="." />
</xsl:template>
</xsl:stylesheet>
my problem is my output comes out something like this
<rowset>
<row>
<Assessment_Group>A </Assessment_Group>
The omni port wizard doesnt understand what the &lt means.
How can I fix this?

I have still not figured this one out. Any help please?

Developing Portable WebServices using Jdeveloper

I am currently using Jdeveloper 10.1.3.2 and I have developed WebServices from my existing WSDL files and deployed the WebServices in OC4J. Everything is working fine now. I noticed that Jdeveloper has created some OC4J specific files like oracle-webservice.xml. Now I want this working WebService Application to be deployed to another Application Server. I am sure it would fail.
My Question is,
1) How can I devlop Web Services using Jdeveloper which can be deployed in any App Server?
2) Will Jdev 11g with JAX-WS will be helpful?
3) Is there any tutorial for developing portable webservices which can be deployed across any App Server.

Hi Frank
Thanks for your response.
So If I remove my oracle-webservices.xml and deploy my Project, Will it work in any App Server.
Also where can I put the contents in oracle-webservices.xml file like
<oracle-webservices xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/oracle-webservices-10_0.xsd">
<webservice-description name="''''''''">
<port-component name="''''''''">
<operations>
</operations>
</port-component>
</port-component>
</webservice-description>
</oracle-webservices>
Thanks

Developing Large Projects with JDeveloper

i have 2 questins :
1 - i don't know is it possible to develop large project such as a total system
with about 20 subsystems and 1000 forms and reports with jdeveloper?
2 - we have planed to build a webapp for each subsystem that it contains MODEL and VIEWCONTROLLER project.with this idea we cann't link from one VIEWCONTROLLER to anather in anather project, for example user can not go to another page from anather project without logon again.
now my very immportant problem is comunication between pages in different projectsand maintain different objects such as USER object between pages.
do you think that building such project with only one application with one MODEL and one VIEWCONTROLLER is correct or building it in differt project is better?
could you please tell me that what is your idea to develop large project with jdeveloper?

dear jan,
I want my users to authenticate once, and have access to the subsystems they are authorized for.
but there is a problem in development and that is with this type of large projects you will have in Model Proj. a lot of AM , EO , VO and in View Proj. a lot of JSPX and XML file. and if i make only one App with one Project for Model and One Project for View, during development for example i want work on one subsystem and others on other susystem. and when i change 1 jspx file i should deploy TOTAL SYSTEM with 20 subsystems completely and i think this is'nt strategy for development.
i think it's good to develop any subsystem in one app with Model and View and finally deploy any subsystem separately.
thanks for your reply

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

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

Deployment of Java WebService with OC4J and JDeveloper

Hi,
I have created a sample java webservice following instructions given in one OTN tutorial (Developing, Deploying and Managing Web Services Using JDeveloper and Oracle Application Server ) at http://www.oracle.com/technology/obe/obe1013jdev/ws/wsandascontrol.htm
We were able to create the webservice as shown in the tutorial but are facing problem while deploying it. The deployment message console in JDeveloper shows one "Deployment failed : ClassCastException".
Some of the lines from Jdeveloper console are ::
"Binding WebServices web-module for application JavaWebService-GetDates-WS to site default-web-site under context root JavaWebService-GetDates-context-root failed"
I have gone through the stack trace in the OC4J console but couldnt figure out much out of it as all the culprit classes are from different jar files...Here is the Stack trace for your ref::

2006-05-05 19:07:12.713 WARNING java.lang.ClassCastException
I am using J2SE1.4.2_08 version. Earlier when I used java 5 version I got an error something like "Found runtime environment 49.0 expected environment is 48.0"....so I moved over to J2SE1.4.2_08 version but now I am getting above error as shown in the stack trace.
Looking at the success message shown in the OTN tutorial it seems that only step that failed while this deployment is Initialization of servlet : Oracle.j2ee.ws.server.JAXRPCServlet for webapplication Webservices.

Hi, thanks for your quick help.
Shay, I agree with you that the specific tutorial uses JDeveloper 10.1.3 and I need to use JDK 5 to run that version of JDeveloper.
Earlier when I used JDK 5 with JDeveloper 10.1.3, I got different error saying "Found runtime environment 49.0 expected environment is 48.0".....so I moved over to J2SE1.4.2_08 version but now I am getting an error as shown in the stack trace given in the very first post to this thread.

Database call out webservices with JDeveloper - help

Hi all,
I am using JDeveloper 10.1.3.0 to generate java proxies for web services and deploy them to my Oracle 10g Enterprise Edition database.
I am able to create the proxy and test the web service, it works fine. When I create a deployment profile and deploy, everything succeeds, I am able to see the PL/SQL wrapper function in the database. However, when I execute the function, I get an error class name <my java classname> not found. This is a case when I execute a web service that runs on our server and requires authentication. I have provided the authentication in the setUsername and setPassword methods of the java proxy.
When I try to do the same with a stock quote web service, I do not get an error, but there is no output either. It returns nothing.
Is this an issue because of the jdk version problem? My database jvm is jdk1.4 compliant and the JDeveloper is 1.5 compliant. But I think there is somehting very basic that I am missing. Can experts please help me with this, I have been struggling for long!
Thank you very much. Any help is greatly appreciated.

Developing Enterprise Apps with Weblogic and WebGain-Studio

Hi everybody,
Is anybody experienced in developing with Weblogic Server and WebGain-Studio
What could be a good environment for working with these components ?
Thanx,
Markus.

Thanks for your prompt reply. I have another question. I am very new to Java development.
In our environment, WebLogic 10.3.6 and JDK1.7 are both 64-bit. However, developers' machine are 32-bit windows. They will have Weblogic server installed locally in their machines for development. Later, the codes will be deployed and run in the 64-bit environment.
Thus, we are developing java program with 32-bit java and compile/run it with 64-bit java. Is it the right way to do it or do our developers need to use 64-bit windows?

WebDev Install with JDeveloper and WLS

I'm familiar with the installation of a JDE WebDev Client and now I've been tasked with a JDeveloper 11.1.1.2 and WLS install. Is there any good guides on how to set this up?
EnterpriseOne 811
Tools 8.98.3.1
Any help would be greatly appreciated.
Thank you,
Al

Hi Al,
Try this:
https://support.us.oracle.com/oip/faces/secure/km/DocumentDisplay.jspx?id=1302209.1
This doc explains what components you need to have on a E1 Client that will be used to build and deploy BSSV Packages to a Bus Services Server. The Combination of JDeveloper and WLS probably indicates that you are intending to setup a Bus Services Server. However, this is only supported as of 811SP1.
If you are running 811SP1, the process of setting up a Bus Services Server involves:
- defining a BSSV instance via Server Manager
- setting up a E1 Client with JDeveloper that will be used to build and deploy a Business Services Package
The following doc has useful links to the MTRs for Bus Services Server as well as other useful resources on BSSV.

Problem with packageing and deploying a sample application

HI,
I have tried to download and install the server in my system. I am able to deploy a sample application using autodeploy utility.
But when i tried to package a new sample application and deploy i am getting 404 error. For application server i have used 7070 port and not the default 8080 port will this a problem to package & deploy sample application provided with this software.
The error is as below:
HTTP Status 404 - /hello1
type Status report
message /hello1
description The requested resource (/hello1) is not available.
Sun-Java-System/Application-Server

Btw, verify that the url you are trying to access is correct. For instance, assuming you deploy app. without --contextroot option. By default, the url is http://<host>:<port>/<web module name>/<value of url-pattern in web.xml> if your app contains servlet. If your app has jsp then it's http://<host>:<port>/<web module name>/<value of url-pattern in web.xml>/<name of jsp>

How to develop a webservice with SAML on Weblogic 8.1

I will develop some webservices on Weblogic 8.1. On the security part, we will
use SAML. Is there somebody who can tell me how to do it? Do I need third party
product? And where I can find samples?
Thanks.
Jian

I will develop some webservices on Weblogic 8.1. On the security part,
we will use SAML. Is there somebody who can tell me how to do it? Do I
need third party product? And where I can find samples?Currently, we don't offer any support for SAML in WLS -- so you would
have to use a third party product. Depending on how you want to use it,
you may be able to use a third party product to create a handler for your
service or client.
However, if you want to use the handler in the server to set the subject
for the invoke, the handler architecture will prevent you from doing
this -- the API you use to set the user
(weblogic.security.service.SecurityManager.runAs() -- see
http://edocs.bea.com/wls/docs81/javadocs/weblogic/security/service/SecurityManager.html)
cannot be successfully used in handler methods. If you wish to do this,
I'm afraid the only way we have to support this is to use a servlet filter.
