Eclipse and JDeveloper

Somebody knows what is the purpose of eclipse with jdevelper? Do I need to install eclipse? I cant find the version that the guide is talking about eclipse SDK 3.0 from the eclipse web site - anyone knows where i can get this?

Parrwez,
If you have the latest JDeveloper (10.1.3.1 or 10.1.3.2), it already has support for editing BPEL services. You need not install Eclipse.

OpenEJB ,Tomcat and JDeveloper 11g

I developed a session bean 3 and export it as jar and put it in web application under lib folder then exported it as war then deployed it in Tomcat integrated with openEJB
I call the session bean through servlet using injection,but the openEJB didn't deploy the beans to the container.
I used this steps in eclipse and netbeans the openEJB deployed the bean.
Does JDeveloper add something to bytecode of the bean makes the openEJB can't deploy the bean?
the following is my code.
session bean:
package model;
import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
public class PrintSessionEJBBean implements PrintSessionEJBLocal {
public PrintSessionEJBBean() {
public String printName(String name){
return "The Name is:" + name;
Servlet:
package view;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.ejb.EJB;
import model.PrintSessionEJBLocal;
public class Servlet1 extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
@EJB
PrintSessionEJBLocal local;
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head><title>Servlet1</title></head>");
out.println("<body>");
out.println("<p>The servlet has received a GET. This is the reply.</p>");
out.println("<p>The servlet has received a GET." + local.printName("Temp") + ".</p>");
out.println("</body></html>");
out.close();
thx.

What specific error did you get when you deployed?
The code seems quite generic - how is the Eclipse version different from the JDev version?

Oracle Service Bus (OSB), Eclipse --- and statement of direction

More specifically: what will happen to the Eclipse OSB plugin/workshop once the JDeveloper port is complete?

B) will it remain as is, without keeping the functionality in synch with new stuff in JDev?
C) will it continue to evolve side-by-side with JDev?
Thx,

I think it is clear that Oracle will remain commited to Eclipse in terms of deploying java applications to WebLogic, they will provide some plugins for some time to come. You will however see oracle specific products, such as OSB, Portal, etc removed from Eclipse and ported to JDev. The reason for this is that Oracle can release new releases within their timeframe. If Oracle rely on Eclipse to deliver some functionality before they can release new products then they will be doing their customers a disservice.
This statement in the SOD clearly states that JDev is the strategic platform and the Eclipse IP will be ported to JDev in the future:
Design-Time Environment
JDeveloper is the IDE of choice for SOA development at Oracle. AquaLogic Service Bus users have traditionally been using the web-based console to design, manage and monitor ESB flows. The web console is a key differentiator for ALSB (now Oracle Service Bus) and will therefore remain a primary design
environment moving forward.
The web-based console was complemented in the 3.0 release with full IDE support in Eclipse. The Eclipse capabilities will be ported to Oracle JDeveloper to provide a
one-stop IDE for all SOA design needs. Until that port is complete, customers will still be able to use the Eclipse environment as IDE (in addition to the web-based

Oracle Coherence Examples with Oracle SOA suite 11.1.1.4.0 and JDeveloper.

Hi,
I am new to Oracle Coherence. I was looking for examples implementing Oracle Coherence step by step so as to get a basic understanding using JDeveloper but most of the examples available are using Oracle Service Bus and Eclipse.
Could anyone please help me in providing link with examples using Oracle Coherence with Oracle SOA suite 11.1.1.4.0 and JDeveloper.
Thanks for the needful.
Cheers,
Varun

Hi Varun,
Please find the answers to your questions below:
1) Could you please let me know how to use this system property -Dtangosol.coherence.override in my application so that I can coordinate between the cluster used by my application and the one started for using Coherence Node.
You need to specify this property in the Java Options of your server or cache node startup script.
2) I was trying to understand how to use this tangosol-coherence-override.xml but the document is pretty confusing. I am not able to understand that whether I am suppose to use it at server level or at application level.
I would suggest extract the coherence.jar and you it would be important for you to have a look at the tangosol-coherence.xml and tangosol-coherence-override.xml. This file is used to override any of the properties specified in tangosol-coherence.xml for your cluster configuration for example, clustername, multicast ip and port or WKA for unicast, logging and so on.
3) Another point is how to coordinate among tangosol-coherence-override.xml, coherence-cache-config.xml and -Dtangosol.coherence.override system property from my application
Ideally you should specify in the java options of your application startup but you can also sepcify using System.setProperty("property", "value") in you code for specifying the various properties
4) How to use the cache updating mechanisms from an application?
I am not clear what do you mean by cache updating mechanisms? If you mean how you can update the cache from application then you can use simple Put, Entry Processor and so on. Refer NamedCache APIs to start with for operations but there many other ways to update the cache from within application or otherwise
Hope this helps!

BPEL Designer and JDeveloper 10.1.3.3

Hi,
I've installed BPEL Process Manager and JDeveloper 10.1.3.3 and started looking at the tutorials. I don't have the BPEL Process Designer on any program menus and I tried following the links to get the Eclipse plug-in but without success. From reading these forums, I believe the designer is now incorporated in JDeveloper but the tutorials all seem to relate the Process Designer and bear no resemblance to what I can see in JDeveloper.
So, can anyone tell me whether there is something else I need to install?
Thanks,
Ian

Hi Ian,
You need to create a new application workspace from application navigator in Jdev.
After that right clicking on the application created will give you an option to create a new project, further into which you will see options to create BPEL project.
Anyhow its better you follow this "http://download-uk.oracle.com/docs/cd/B14099_15/integrate.1012/b15813/ordintro.htm" tutorial as it will help you in
getting familiar with Oracle JDev environment.

Problem launching a jsp page with eclipse and tomcat

Hi,
I have just started using eclipse and tomcat for creating dynamic web pages. I tried to launch a jsp page after starting the tomcat server with the URL: http://locahost:8080/HelloWorld/, an error page was displayed as below:
HTTP Status 404 -/
type Status report
message /_
description The requested resource (-) is not available
Apache Tomcat/5.5.17
I didn't get any error at the console and when i just typed http://localhost, a pop up menu saying that the connection was refused when attempting to contact localhost.
I'm not sure what is the problem here. Could it be the permssion to the localhost is not granted by the system as the eclipse IDE is running using linux?
Hope someone can help.
Thanks.

Crystal Reports for Eclipse and CR2008

SQL-Server 2005
CR 2008, Ver.12.0.0.683
Crystal Reports for Eclipse Plug-in Details:
all Plug-in-files from Business Objects have the Versions 1.0.4.v1094 or 11.8.0.v20060727 except "CR for Eclipse Dev.Guide": Ver. 1.0.0.v1094
I created a report with CR 2008 and load this report with eclipse. A preview in CR and eclipse is running perfect.
When I bind this report to a jsp I get the error "Es wurde keine Rowsetspalte für das SQL-Ausdrucksfeld "strRefNo" gefunden", in english
"no rowset-column for sql-statement "strRefNo""
General this kind of SQL-statement is not working. This statement is a function which needs first a value from the database.
When this value is fixed in the statement, the report is running in the jsp otherwise I get the error.
When I delete this statement in eclispe, save this report, redo my delete and save the report again, the report is running with jsp!
May be, there is a version conflict between CR and eclipse.
I have to create the reports in CR2008 but I can not save the report in CR2008 to an older version.
Is there a newer version for eclipse, which works with CR2008? I could not find any other version.
Do you have other ideas?
Thanks!
Jens

Hi Bryan,
thank you for your good informations.
I have downloaded the complete new eclipse and I don't get this error anymore.
But in the next step, I tried a report with subreports. This is complete not working in Eclipse. When I load this report to Eclipse Ican see and click into the subreports. Each subreport is working in Preview, but the whole reports does not work (black screen), I get the error

Soa 11g and jdeveloper 11g user defined extension function

I have developed a set of extension functions,
in design time for the previous version, I can put the deployment file (jar file) that contains the extension functions in the %JDEV_HOME%\jdev\lib\ext directory and jdeveloper recognizes the set of extension functions if previously i have defined an xml descriptor with every one of the functions i need to include in the panel.
Now, with the jdeveloper 11g i have tried the same, and jdev recognizes the functions, but when I am going to test one transformation that includes the extension function, the parser is not founding the jar file; the error (in spanish) is:
XML-22045: (Error) Error de funcion de extension: No se ha encontrado la clase '
Falta la clase: aac._shared.extensions.xsl.XmlW3cDomFunctions
Clase Dependiente: oracle.xml.xpath.XSLExtFunctions
Cargador: main:11.0

Configuraci≤n: system property PCLMain.createExtensionManagerLoader()
Esta carga se ha iniciado en main:11.0 mediante el mΘtodo loadClass().
La clase que falta no esta disponible desde ningun origen de codigo o cargador del sistema.
my dude is:
+ at design time, where can I put the jars with extension functions to make one transformation function used in a mediator component can works fine?
+ at runtime, where can I put those libraries? (in the previous version, we can put this libraries in the %APP_SERVER%\j2ee\home\applib, or create one shared library and reference it in the oracle.bpel.common shared library declaration of the server.xml configuration file).

Cannot make .war file using tomcat with eclipse and ant

i have made all necesary configuration for deploying application using eclipse and ant for the tomcat server.
when i start the server by clicking the tomcat icon on eclipse toolbar, the message is prompted that "missing application web.xml and using defaults". i have placed the web.xml file in the web/WEB-INF directory of the source project directory.
also when i use ant by right-clicking on the build.xml file and choose Run as ant.. the process creates a desired .war file in webapps folder of the tomcat server but that war file does not works.

So is context.xml actually overwriting the settings found in server.xml?I think so. The way I understand it is the the context.xml file saves you from having to edit server.xml. It is preferred for each web app to do its own config, rather than lumping them all together in server.xml.
And what would be the best way to create the war file? IAt its heart, a WAR is just a zip file with its contents laid out in according to the specification of a web application directory structure.
So the simplest way to make a war file is to zip up your directory structure with a tool like winzip, and rename it to be myApp.war.
Regarding ant, I would recommend you take a look through [url http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/index.html
]this tutorial. It explains the basics of website layout, configuration and deployment.
On [url http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/source.html] this page in particular, it includes a link to a basic ant file that you can use as a starting point.

Eclipse and Java EE 5

Hi all,
I'm going to develop an application based on Java EE 5.
I'd like to use webservices, EJB 3.0, GlassFish, Portlets and everything should be than connected with JBI, bussiness logic will be modeled with BPEL.
My question is which IDE would be better for me. I liked elipse for my JavaSE, Spring etc. development but I don't know the situation in JEE 5. Will be a problem to use these technologies with eclipse? Is eclipse (WTP?) ready for this project? With which plugins?
Thanks
P.S. I'm only deciding between eclipse and netbeans and I'm not interested in which IDE is little better but if eclipse is roughly on the same level with Java EE 5 and other technologies mentioned.

What do you mean by "I r click the server"? Do you mean in the Servers
view and choose Run or Debug?
Normally, Tomcat comes ready to use on port 8080. You can change this by
doing the following:
1) Expand Server in the Project Explorer view.
2) Exapnd Tomcat v6.0 Server at localhost-config
3) Double-click server.xml
4) Search for 8080
5) Verify that you have:
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1"
redirectPort="8443" />
This should mean that Tomcat is using 8080 not 80. If other, change to
8080 and try again.
(80 is usually what your browser is using.)

Question concerning Eclipse and Tomcat Plugin and JSP

I have a Tomcat-Project that I am working on in Eclipse and quite a few external JARs. Everything works fine, when I run my Test class within my project (in Eclipse). But as soon, as I am trying to call the jsp in my browser I get Exceptions: "java.lang.NoClassDefFoundError: org/apache/log4j/Logger" for example, which tells me that in the browser it can't find the JARs... I'm guessing something's wrong with the classpath but I was thinking that Eclipse would handle those things for me...
I've added the JARs to my project via Eclipse (Properties -> Java Build Path -> Libraries -> Add external JARs). And I've created a subdirectory for my jsp files and allowed my project to update the .xml file for the settings and all... Do I need to do anything else? What have I done wrong so far, have I forgotten to do?

I solved the problem...

Setting up eclipse and tomcat

Does anyone here have any expertise configuring these two products?(eclipse and tomcat)
I have my tomcat server running and it process them jsp pages just fine. I have also installed the plugin to get tomcat configured with eclispe.
I am just having problems running a jsp file directly from tomcat. it always points to a file on the hd and not to the webapps area like it's supposed to......

Sure - we use that combo for development all the time.
What's the problem specifically? Did you create a new Tomcat project in Eclipse? If you did, then it will automatically add the project's web path as a context to Tomcat, and you can browse directly to it using your browser.
FYI - note that the context that is created is going to point to the eclipse workspace directory - NOT the default webapps directory that you might have configured for Tomcat. That's OK.

Eclipse and Tomcat questions

Hi everyone,
Lastnight I setup Eclipse to work with Tomcat, which works very good, but there are something I don't understand.
1. My files are put in my workspace in (C:\Documents and Settings\...etc)
How does Tomcat (which is installed in C:\Tomcat) know that it should get the files from my workspace directory?
Because in the C:\Tomcat directory I can't find any .XML file that refers to my workspace directory.
2. How I developed my servlets till now, I had some other free editor, I needed to compile my servlets then restart Tomcat and then test it.
With Eclipse + Tomcat plugin, all I need to do save the servlet and apparently the source code is compiled automatically. All I need to do is refresh the servlet in my browsers (very handy and easy to develop like this). But my question is, does Eclipse compile the servlet automatically after saving? And why doesn't tomcat have to be restarted?
Just a few questions to understand it a bit better, I'm really happy with this setup as it makes everything a lot easier.
Regards,
