Does anyone knows this ..

In your deploy message it says that it can't initialize your servlet because it is missing a java class from the logging framework that is used by hibernate. It might also be possible that that logging framework ([SL4J|http://www.slf4j.org/]) is configured to use a logger that is not available in your Netweaver 7.3 installation. Maybe check the documentation of sl4j for details. There is also a [document|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/bf0d57db-0c01-0010-6fa3-83503981eed4] about Hibernate on Netweaver but that was back when Hibernate did not use sl4j. Probably you just need to add the sl4j library to your libs.

A web developer problem while running a web application

Hi all,
I'm novice to J2EE.
I've encountered a problem while accessing the deployed module in weblogic 8.1 server.
I'm sure that the webapplication module is deployed as i saw my module in administration console & also the status said that it is deployed.
when i access my web application by specifying the proper server and port no and context root it is showing
either 505 - resource not found error(http://localhost:7001/Suresh-2/Suresh) or 404 - not found error.( http://localhost:7001/Suresh-2/Suresh)
Now let me elaborate what i've done till now.
My webapplication folder structure is : C:\bea\user_projects\domains\mydomain\applications\Suresh\WEB-INF\classes\Sai\ServExamp.class
My servlet is ServExamp.java
I created a folder called "Suresh". In that folder created another folder called "WEB-INF". In WEB-INF created a folder called "Classes".
Since my servlet is in package "Sai", the .class file reside in \Suresh\WEB-INF\Classes\Sai\ServExamp.class
The source code is :
package Sai;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class ServExamp extends HttpServlet
public void doPost(HttpServletRequest req,HttpServletResponse res)throws IOException
PrintWriter out=res.getWriter();
java.util.Date today=new java.util.Date();
out.println("<html>"+"<body>"+
"<h1 align=center>HF\'s Chapter1 Servlet </h1>"
+"<br>"+today+"</body>"+"</html>");
Now i'm almost done creating a web application. Next, I constructed a simple web.xml descriptor that gives a web friendly name for my servlet, and points to the servlet. I constructed web.xml descriptor file in the WEB-INF folder (C:\bea\user_projects\domains\mydomain\applications\Suresh\WEB-INF\).
The web.xml file source is :
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Hello World Web Application</display-name>
<description>Test Servlet</description>
<servlet>
<servlet-name>ServExamp</servlet-name>
<servlet-class>Sai.ServExamp</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServExamp</servlet-name>
<url-pattern>/Suresh</url-pattern>
</servlet-mapping>
</web-app>
Now I have told Weblogic that the URI /Suresh corresponds to my servlet "Sai.ServExamp".
My Web Application is ready to be deployed at this point. I logged onto Weblogic's admin console,
1) clicked on deployments, then navigated to "Web Application Modules" .
2) Clicked "Deploy new Web Application Module"
3) Navigated to the location of your web application folder (Suresh). There was a radio button next to it indicating that I can select that folder as a valid web application.
4) I Clicked that radio button and clicked "Target Module".
5) It informed that my web application "Suresh" will be deployed to myServer.It asked a name for my web application deployment. By default it was "Suresh"
I clicked Deploy.
6) After deployment, my web application "Suresh" appeared in the "Web Application Modules" tree on the left.
I Clicked on "Suresh"( my web application) then clicked the testing tab, then clicked the link shown there(http://localhost:7001/Suresh-2).
It was not showing my servlet (showed a 403 error)
Error - 403
This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
I think so it came b'coz I don't have an index.html or index.jsp page.
7)Instead,I added my servlet on to the URL it provided.
http://localhost:7001/Suresh-2/Suresh
It is showing these error code: Http: 505 resource not allowed
The page cannot be displayed
The page you are looking for cannot be displayed because the address is incorrect.
Please try the following:
If you typed the page address in the Address bar, check that it is entered correctly.
Open the localhost:7001 home page and then look for links to the information you want.
Click Search to look for information on the Internet.
when i just type : http://localhost:7001/ -> Error 404 not found error
it's showing
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
I want to run my web application & any help would be appreciated.
Thanks in advance.
with regards,
S.SayeeNarayanan.
Note: I even deployed my war file, which i got by execution of (jar cv0f webapp.war . ) command from the root directory of my web application i.e. Suresh
Then executed my webapplication it is showing
error-505 resource not allowed.

Problems about deploying Oracle web application (Forms, Reports)

I am going to deploy Oracle web applications (Forms and Reports) and plan to use the same server machine for both Application web server and Database server.
1. How can I enable SSL (for data encryption) on Application web server for Oracle Forms ?
2. Since both Application web server and Database server will use the same machine, do I still need Oracle Advanced Security for data transmission between Application web server and Database server if data encryption for transmission is required ?
3. Can I user Oracle Forms to call Oracle Report on web as I did in Client/Server in the past ?
Experts like you may have come across such problems. Would you please give me some opinions/ideas ?
Regards,
Richard

1. check the paper about the Forms servlet architecture on otn forms section for SSL tips.
3. Check the reports and forms integration paper on otn too.

Integrating a Java web application into the SAP NetWeaver Portal

Hello experts,
We have a requirement to integrate a Java based web application into the SAP NetWeaver Portal using iView/iFrame technology. The Java based web application is completely independent from the SAP environment but should be displayed as part of the SAP Portal environment. The other requirement is the main navigation menu for the Java based web application should be configured and provided in the SAP Portal.
Any pointers on how exactly this can be done would be of great help.
Also how can the SSO (Single-Sign-On) to the Java application be implemented so that the user can logon to the java application through the portal without providing the user credentials again.
Thanks in advance.

Hi,
I think you can use URL iviews to integrate your java web application with EP. you have the option of doing SSO with the application as well.
Have a look at the sap help material

WEB.XML gives me an error while deploying a Web Application in Weblogic 5.1

I have a Web.xml which I copied the one from their documentation and edited for my servlet specific data. When I try to deploy it I am getting the following error.

          /webapps/La/'

          Can you throw some light on this? I have included the first three lines from the WEB,XML file where weblogic is choking.

          Hi Jacek,
          Thank you for your suggestion. I changed the Web App version to 1.2 instead of 2.2. It worked. Thanks once again for the timely response. I really do appreciate it.

JBO-33001 bc4j.xcfg CLASSPATH problem in deployed java web service

Hi
I have deployed a web service that uses a simple java class to update some BC4J EO's.
I have included the deployed jar files in the OC4J Classpath.
I have also deployed the web service to the application server.
I then call the web service from BPEL.
During the web service call, I'm getting the following exception:
exception on JaxRpc invoke:
start fault message:
oracle.jbo.ConfigException: JBO-33001: Cannot find the configuration file /cb/test/peoplebc/common/bc4j.xcfg in the classpath at oracle.jbo.client.Configuration.loadFromClassPath(Configuration.java:367)
I've checked that the file is deployed in the MiddleTier jar file, so not sure what to do.
Any ideas most appreciated.
Cheers
Chris

Hi,
This may sound a bit stupid, but as a quick and dirty solution i just copied the common directory with the bc4j.xcfg file where it is looking for it. This makes it at least work. Any updates to the xcfg file done will of course not be reflected.

Hi,
We did that earlier, too (modified existing domain).
Also, after that, we created new domain and extended it according to you suggestions but no change.

Deploying Java Web Application (WAR-File) into a cluster environment

Hi,
we have a web application which has to read from and write to the file system.
Since a short time we have a cluster environment (2 parallel servers) and since thisa time we have the problem, that files are worked double in the cluster. The application is working on both servers now and so we have this problem.
Does anybody know how we have to deploy the application correctly in a cluster environment or do we have to change anything in our source code of the application?
I didn't find any documentation about this.
At the moment we have deployed the application on one of the two servers only, but I think there must be a better way to solve this problem.
Thanks for your replies.
Regards
Thorsten

Hi,
I think first you need to wrap it into an EAR file, then you can deploy it.
As far as I know standalone deployment of WAR is deprecated as of 640.

Hopefully this tutorial also gives some idea:

Hi,
This is a problem with your DNS settings (or lack of), not with Sun Java System Application Server/Access Manager.
You will need to setup DNS before installing.

Problem deploying a web application (war)

Hello,
I am having a problem deploying a web application in Tomcat.
Here is what happens:
-I copied the war file into the webapps directory.
-I started Tomcat.
-Tomcat automatically expanded the war file into a directory of the same name.
The problem is that I get the following error: "The requested resource (/jadmin) is not available." when I try to access my web application
Can anyone please help?
Thanks in advance,
Balteo.

Hi,
check the Tomcat log file <tomcat_dir>/logs/localhost_log.yyyy-mm-dd.txt and see if there is an error corresponding to the deployement of the (/jadmin) context.

Problem while deploying WD application thru SDM

Hi friends ,facing problem while deploying webdynpro application on SDM.It takes much time deployment but for the past 1 or 2 day its not working properly ..i..e error is coming while deploying WD application................................................"Cannot login to the SAP J2EE Engine using user and password as provided in the Filesystem Secure Store. Enter valid login information in the Filesystem Secure Store using the SAP J2EE Engine Config Tool. For more information, see SAP note 701654.."
If how know how to resolve this then waiting for ur response..
Thanx in advance
Hanif

Hi Hanif,
The SDM password should be reset if it is not the same as mentioned in your Filesystem Secure Store or vice versa.
If you have changed your administrator password, kindly do change the same in secure store as well via the config tool.
Use the Config Tool to change the entry in secure storage as follows:
1. Start the Config Tool.
           (Go to <drive>:\usr\sap\<SID>\<instance>\j2ee\configtool --> configtool.bat.)
2. Select the secure store node.
           The configuration for the secure storage in the file system appears.
3. Select the admin/password/<SID> entry.
4. Enter the administrator user's new password in the "Value" field and choose "Add".
5. Choose "File" --> "Apply" to save the data.
          Note: Contrary to the message that appears, you do not need to restart the server or cluster for this change to take effect.
6. Finally restart SDM server.

Anagha

Problem with ClassCastException in web application

Hello,
          I'm trying to deploy a web application in WLS 5.1 and I'm getting the
          "dreaded" ClassCastException every time when JSP tries to read a bean
          from the request or session. Under my architecture (actually it's just
          the regular "model 2" ) bean is populated by a servlet, set on the
          request and then retrieved by JSP (servlet forwards to JSP). Everything
          work fine when I register servlets in weblogic.properties, but
          ClassCastException is thrown on any attempt to read from the request if
          the same JSPs and servlets are deployed as web application.
          Has anybody come across the same problem?
          Thanks in advance for help.
          Alexander


Hello,
          This is all well and good as a temporary bug, but it's totally unrealistic for
          the future. Two points:
          * The ClassLoader doesn't need to be discarded, it just needs to be cleared.
          * Other servlet engines seem to be able to handle this.
          Hope it's on its way to resolution!

Hi,
I think you are trying to test the Hello world EJB example shipped with the product. As a first
step I would recomend you to go through every line of the document on deploying this application,
since, I too have experienced many errors while trying to deploy the sample applications, but on
following the documentation, I subsequently overcame all the errors and have been working with the
applications. So please follow the steps in documentation and let me know, if you still encounter any
issues.
Regards
Raj
