JSP Portlet Returns 404 HTTP Error

Hello,
I have a portlet provider that is a simple JSP page that passes a select query string to a table in the database, straight forward. In JDeveloper the JSP and related Classes work fine. As a portlet the provider is registered and the JSP page where the query is entered all function fine, but when a query string is entered and the submit button is pressed the result is a blank page or 404 error. Any thoughts?
Thanks,
Jeff

i would guess the action parameter in your form is the problem.
in a standard JSP, called "myPage.jsp", if you want to page to post to itself,
you simply use <form action="mypage.jsp" method="post">
however, a portlet is simply a content region on a PL/SQL page.
your JSP needs to use the Java Portlet APIs to determine what page it's on,
and then post to that page, listening for params on the refresh.
in other words, the JSP does not exist as a unique entity,
and therefore would be expected to generate a 404 on request.
see the Parameter Passing Java Portlet sample for details.
good luck,
rich

A 404 error is a server error and can only be 'cured' by the mainatiner of that server not by you.

DMM 5.1 - 404 HTTP Error

Hi,
I am trying to connect to DMM5.1 admin page for the first time and yet getting a 404 error. I am sure I can ping the hostname of the DMM and it matches the same one configure on DMM applicance. I am using the URL http://<DMM Hostname>:8080 and no luck. I am getting the following error:
Any ideas?
HTTP Status 404 - /dmsadmin/main.jsp
type Status report
message /dmsadmin/main.jsp
description The requested resource (/dmsadmin/main.jsp) is not available.
Thanks

Glad to see someone else is having this issue. I've used VMs of the demo 5.1 without a problem, and on several different machines. Now I'm trying to set up a server from scratch and get the same issue as the previous post.
I know my DNS is working, I can ping the hostname of the server fine, and I can access another DMM that is running as a VM fine, but not this machine. I have restarted everything and flushed DNS on the computer I am trying to use to http to the DMM (when I had the same IP address for one physical and one virtual DMM, and tried to disconnect one and switch between the two).
I have reloaded a new ISO, one I downloaded and one was downloaded by a coworker, and both do exactly the same thing. My next step will be to try to download and run the 5.2 ISO. If that doesn't work, I don't know what to do.

ICal Server 404 HTTP Error

Hi all,
I'm having a perplexing issue with iCal server. Every now and again, iCal reports that it encountered an HTTP 404 error with my iCal account on one of my Lion servers. I can't seem to figure it out. Anyone else having this issue? Any suggestions?
Chris

Do you ever get 404 errors accessing server.example.com/webcal ?
If you are using SSL check that your SSL sertificat is correctly set for iCal. In Server app go to Hardware => Server => Settings => SSL Certificate.
You can try enabling the webcal manually by doing this:
iCal with SSL:
sudo webappctl start com.apple.webapp.webcalssl
iCal without SSL:
sudo webappctl start com.apple.webapp.webcal
This rebuilds you apache httpd.conf and restarts apache which suppressing often solves problems in Lion Server. Alternatively you might try to disable all services, change your servers hostname (just go through the process but change the hostname to what the hostname already is) and then re-enable all your services.

Error in Webservice Call HTTP error (return code 404, message conn failed)

Hi
We wish to call a standard EP7 webservice through ABAP.
When we try to create consumer proxy , we get the following error.
HTTP error (return code 404, message "conn failed")
Message no. SPRX090
==> Display Error Document
If you want to generate a proxy for an external WSDL document by specifying a URL, check that the proxy settings of the system are correct (transaction SICF - Client - Proxy Settings). If you want to generate a proxy for an XI Repository object, check the connection to the Enterprise Services Builder as follows:
Check List for Setting Up a Connection to the Service Repository
1. The address of the Enterprise Services Repository must be known in the SAP system
Check with report SPROX_CHECK_IFR_ADDRESS
The address is taken from the following parameters in the exchange profile ('Connections' section):
com.sap.aii.connect.repository.name: Server (for example,pwdf0436)
com.sap.aii.connect.repository.httpport: Port (for example, 1080)
com.sap.aii.connect.repository.contextroot: Root (for example,rep)
The logon data is also read from the exchange profile ('ApplicationSystem' section):
com.sap.aii.applicationsystem.serviceuser.name: User
com.sap.aii.applicationsystem.serviceuser.pwd: Password
As an alternative to using the exchange profile, you can maintain the RFC destination SAP_PROXY_ESR. If this RFC destination is maintained it will be used by the proxy generation in place of data from the exchange profile to access the Service Repository. In this case, the Exchange Profile will even not be read.
The RFC destination has to be set up using transaction SM59 and should look like this:
RFC Destination: SAP_PROXY_ESR
Connection Type: G (HTTP Connection to External Serv)
Description1: ESR for Proxy Generation
Target Host: esr_host
Service No: 1080
Path Prefix: rep
Logon and Security:
Basic Authentication: active
User: esr_user
Password: esr_password
2. The HTTP Framework of the Web Application Server must function
Check with report SPROX_CHECK_HTTP_COMMUNICATION
If necessary, contact your system administrator. Please be aware of the fact, that the HTTP framework is depending on the application server. Thus the result of the report may differ for different application servers.
3. Proxy generation must interpret the data of the Enterprise Services Repository correctly
Check with report SPROX_CHECK_IFR_RESPONSE
you can also login in dev and go to Xn se91
enter msg id SPRX and msg no 090
select the message and click on long text..
you get the same message in a formatted manner..
How to get rid of this ?

When trying to download Acrobat Pro XI Student I only get this " http error: 404/support/downloads/dlm/main.jsp " warning.

Hi!
When trying to download Acrobat Pro XI Student I only get this " http error: 404/support/downloads/dlm/main.jsp " warning. This happens with Akamai and the altervative method too. I've paid it, is this because Adobe hasn't progressed my payment yet?
Kind regards, xpooler.

Luckily the problem seems to have vanished. I am not sure what happened but I think the reason was one of the browser extensions, thanks for the advice anyway!

[Error running JSP portlet in JDeveloper

I'm writing a JSP portlet with JDeveloper 9.0.3.
The "index.jsp" works OK, and I can see the registration URL for my new provider.
I deploy the application to Oracle9iAS 9.0.2.0.1 Application Server succesfully throught DCM servlet, register the new provier and I can run the portlet succesfully.
But if I try to run the "pasa_parametroShowPage.jsp" inside the Jdeveloper, I get an HTTP 500 Error :
java.lang.NullPointerException
     void htdocs.pasa__parametro._pasa__parametroShowPage._jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
     [htdocs/pasa_parametro/pasa_parametroShowPage.jsp]
          pasa_parametroShowPage.jsp:12
Line 12 is:
Hello <%= pReq.getUser().getName() %>
Thanks in advance.

In order to successfully run, "pasa_parametroShowPage.jsp" must be called in a portal context - JDeveloper does not do this.
Therefore, when called from JDeveloper, the PortletRenderRequest object is not present, hance the null pointer exception.
You shouldn't attempt to run this JSP directly from with in jdev. You'll notice that if you point a browser directly at that JSP, you will get the same null pointer exception.
If you need to debug this JSP in jdev, you can use a portal instance **or** the test harness (http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/TESTSUITE/PDKTEST/PDKTEST.ZIP)
to fire http requests at JDeveloper's embedded OC4J.

AdControl error: HTTP error status code: NotFound (404)

For over a week now, a Silverlight WP 8 app with an AdControl configured for "test_client" continues to report this error and thus no bing ad visible either while running from an emulator (8.1 512) or from a WP 8 device. If I change the AdUnit
to use a PubCenter ID it works fine on the device and ads are displayed. The emulator connects to the Internet just fine via IE.
Could the ad server not be responding to the "test_client"?
Could someone let me know if it has worked recently for them? I tried contacting MS and no one seems to have an app configured with the test ad... I could give MS so many helpful suggestions. But looking at the hundreds of un-answered posts here - I
suppose they're busy with Windows 10...and have they asked developers if they're willing to put up everything on the cloud? all the while people still waiting to see the 'start' button on Windows 9?
here's the trace
Ad Err: NetworkConnectionFailure,Microsoft.Advertising.Shared.AdException: HTTP error status code: NotFound (404) ---> System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned

Hi Ravi,
Reward points if this helps
The J2EE server might be overburdened and cannot accept the call. The 'Receive'servlet is not called. You will find further details on the HTTP status code definitions under "http://www.w3.org". Check the accessibility of the server by calling: http://<hostname>:<port>/MessagingSystem/receive/AFW/XI.
The Listener Beans of the affected connection (AFW, Marketplace, BC,see above) were not registered or the log-specific Event Handler was not found.
Check out this trouble shooting guide for SAP XI...Section 7.4.4.4 talks about exactly the same problem:-
