Http and ftp protocol extremely slow (pop working well though)

Hello. Starting today, on one of my macs, http and ftp protocol are extremely slow (page load 90 sec. instead of 2) (pop working well though). Provider finds nothing, on second mac all is fine (same cable, same settings … ). Cable connection, checked both sockets, changed cable, no change. Since pop3 protocol seems to work fine, this does look like a software problem to me. (Repaired permissions, no other tests or means. All used software up to date (OSX10.6.8 etc.))
I'd be thankful for any idea.

Not at all. Then I turned on NetBarrier, for testing and to avoid any damage (piece of software I don't employ in vain), and all slowed down again, but not quite as badly as before. Restarted, and now it seems back to normal with all extensions loaded. (I had done that before, obviously, and with no outcome, so it can't very well have been just that. But what?)
I'll watch and learn, and report back; unless you have any further suggestions for the moment. Either way, thankyou very much so far.

Maintaining Sessions between http and https

I have a web application in which I want my users to view the login page over SSL and send the login request via SSL also, but then I want to revert back to http://
My problem is, and i've seen this problem on loads of boards with no real resolution, during the login I set some objects with in the session that are used to display information in other parts of the site... but the session object is being lost!!!
I am using Tomcat as my web server, I saw an article on JavaWorld titled "mix protocols transparently in web applications", and apparently to over come this problem if you are using WebLogic 6.1 there is a parameter in the weblogic.xml file that must be configured, but I cant find a similar one on Tomcat!!!
Thanks in advance

Thanks a million for the answer, I have got it working now, but I had to do something a little different for any one else who experiances this problem I'll go through it... I set an attribute in the context which was named the the value of the current session id and contianed the session object. Then when leaving the login handeling in my dispatcher servlet I apended the session id to the url of the next jsp called. In this jsp then I retrived the "secure session" object from the context, this so far is what you suggested.
But then I had to loop through "non secure session" object's attributes and set them in the "non secure session" object, that is I was not just able to reset the "non secure session" object equal to the "secure session" object as when I went on to the next page it was reset to the "non secure session" object again!
The fact that the session object is changed when moving between http and https is (according to Tomcat buglist) a bug of Tomcat 4.1 and did not occur in tomcat 3.2

JSF / Switch between HTTP and HTTPS

Hello!
I want to switch between HTTP and HTTPS using JSF.
Under Apache Struts framework I can use struts extension "sslext.jar" to configure switching between http and https in one web application.
e.g. Login-jsp should be secured, all other jsp's should run unsecured.
Any ideas?
regards
Harald.

Thanks,
I made the necessary enhancement for the second phase, password confirmation required when return to SSL zone after leaving it after a succesful login.
I did the following:
1) create a class in the application scope and/or singleton class with the servlet paths that require SSL
2) create a plugin that reads ActionConfigs from the ModuleConfig
3) create a filter that sets a request scope flag that says that password must re-entered.
Code Extracts:
1) MainshopContainer application level parameter singleton class:
private static HashMap sslZoneMap = new HashMap(50); // key = servlet path of request, example /login.do
public boolean isInSSLZone(String servletPath)
return this.sslZoneMap.containsKey(servletPath);
public void addToSSLZone(String servletPath)
this.sslZoneMap.put(servletPath,null);
public int getNumberOfActionsInSSLZone()
return this.sslZoneMap.size();
2) Struts plugin
add a call to loadSSLZoneMap in plugin init method:
loadSSLZoneMap(config, mainshopContainer);
private void loadSSLZoneMap(ModuleConfig config, MainshopContainer mainshopContainer)
throws ServletException
try {
ActionConfig[] actionConfigs = config.findActionConfigs();
for (int i = 0; i < actionConfigs.length; i++)
if (actionConfigs.getParameter().indexOf("/jsp/account/") < 0) // /account/* = URL path for SSL zone
// not found = not ssl zone
System.out.println("loadSSLZoneMap, following actionConfigs excluded from SSL Zone: "+actionConfigs[i].getPath());
else
// found = ssl zone
String servletPath = actionConfigs[i].getPath()+".do";
mainshopContainer.addToSSLZone(servletPath);
System.out.println("loadSSLZoneMap, following servletPath added to SSL Zone: "+servletPath);
System.out.println("loadSSLZoneMap, number of actions in SSL Zone: "+mainshopContainer.getNumberOfActionsInSSLZone());
catch (Exception ex)
ex.printStackTrace();
throw new ServletException("Exception caught in loadSSLZoneMap: "+ex.toString()+" Initialization aborted.",ex);
3)
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
String servletPath = req.getServletPath();
boolean secure= this.mainshopContainer.isInSSLZone(servletPath);
The wole picture:
The filter adds a RequestDTO object that includes all request parameters, one of them is the secure flag.
I have a session scope class UserContainer that includes all the session parameters, one of them is the lastRequestDTO.(last made request)
At the end of all my jsp's I set the lastRequestDTO variable.
In that method I set the passwordConfirmationRequired flag if needed:
public void setLastRequestDTO(RequestDTO _lastRequestDTO)
if (this.lastRequestDTO != null && this.lastRequestDTO.isSecure() != _lastRequestDTO.isSecure())
this.setPasswordConfirmationRequired(true);
this.lastRequestDTO = _lastRequestDTO;
I read the passwordConfirmationRequired in all my jsp's in the SSL zone that allow editing or deleting and if that flag is true, a valid password must be re-entered in order to make the updates.
When the password is OK I reset the passwordConfirmationRequired to false.
I need some help for the first phase, that is SSL setup for all actions related to jsp's with url path /account/*
I tought I could define it in the web.xml:
<security-constraint>
<web-resource-collection>
<web-resource-name>All Account Related Pages</web-resource-name>
<url-pattern>/account/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
but that doesn't work and finnaly understood why:
Example: /WEB-INF/jsp/account/login.jsp corresponds to /login.do
The url pattern /account/* at the container level is never encountered.
Is it allowed to declare the following action path: /account/login instead of /login?
If yes I could add following prefix /account to all my action paths and forward paths and this could resolve my problem.
What's your opinion?
If no, would your library resolve this?
Will all the Struts/JSP/JSTL url generating tags pick-up the required protocol (http/https) according to your configuration file?

Fred

Difference Between Transport and message protocols in XI

Hi,
Can u please explain with some example , Difference Between Transport and message protocols in XI.
thanks
dhanush

Hi dhanush,
This two can have different attributes which were assigned in the adapter metadata. Please see this help for some info on this:
http://help.sap.com/saphelp_nw04/helpdata/en/79/e462405c910272e10000000a155106/content.htm
Go to SAP BASIS 6.40 or 7.00 software compoenent and open namespace http://sap.com/xi/XI/System. Go to Adapter objects and open Adapter metadata. Then open any adapter. Here you can see all the properties of your adapter which support.
Transport protocol gives information about outside of message details, kind of system, security details.
A transport protocol is a network protocol that has the capability of transferring some payload from one node to another, thus providing some level of transparency from the underlying network.
Transport protocols are used as a mechanism to move payloads around a network. Typically, a payload will have a transport binding associated with it. For example, SOAP (acting as a payload) has a predetermined binding for HTTP (a transport protocol).
Some common transport protocols include: HTTP, HTTP-R, SMTP and BEEP.
Message protocol gives you an idea of message type XI payload

Types of DTP , Diff between Standard and Error DTP

Hi experts,
What is DTP , are the Types of DTP , Diff between Standard and Error DTP , how it works in BI 7.0.
I will assign points for your valuable answers.

Hello ,
Data transfer process (DTP) to transfer data within BI from one persistent object to another object, in accordance with certain transformations and filters. In this respect, it replaces the data mart interface and the InfoPackage. As of SAP NetWeaver 7.0, the InfoPackage only loads data to the entry layer of BI (PSA).
The data transfer process makes the transfer processes in the data warehousing layer more transparent. Optimized parallel processing improves the performance of the transfer process (the data transfer process determines the processing mode). You can use the data transfer process to separate delta processes for different targets and you can use filter options between the persistent objects on various levels. For example, you can use filters between a DataStore object and an InfoCube.
Data transfer processes are used for standard data transfer, for real-time data acquisition, and for accessing data directly.
1.Benefit: Data Distributionwithin BI Capabilities (from PSA or InfoProviders to InfoProviders)
2.Improved transparency of staging processes across data warehouselayers (PSA, DWH layer, ODS layer, Architected Data Marts)
3.Improved performance and high scalability
4.Separation of delta mechanism for different data targets: delta capability is controlledby the DTP
5.Enhanced filtering in dataflow
6.Repair modus based on temporary buffers (buffers keep complete set of data)
See these docs for more info

Switching between https and http requests

Hi,
Our application is built using ADF 10.1.3
This application need to be integrated with an in house built single sign on system. ( SSO system is built in C# and .NET)
This single sign on system only understand https request. Once user is validated against single sign on system, our application's authorization page is called in HTTPS mode. Once the user is authorized, he is forwarded to home page. While forwarding to home page, we want to convert the HTTPS request to HTTP.
Currently once the user is authenticated, all requests are happening in HTTPS mode.
We do not know how to make http request from existing https requested page.
Any help is appreciated.
Thanks
Ranajit

Hi,
the way to do this is by redirecting the call from a PhaseListener or command button. The solution Avrom refers to is a PhaseListener that uses XML configuration file to determine whether or not the page you are navigating to requires https or http. The code that handles the protocol switch is printed below
* Determines if the requested page requires SSL and if the current protocol
* meets this need. If not the protocol is switched between http and https
* @param viewId
* @param pageRequiresSSL
public void handleProtocolSwitch(String viewId, boolean pageRequiresSSL)
    ExternalContext exctx = FacesContext.getCurrentInstance().getExternalContext();
    boolean isSecureSSLChannel = ((HttpServletRequest)exctx.getRequest()).isSecure();
    // pages that require SSL and SSL is on, or pages that don't require
    // SSL but SSL is on and should be kept
    if (pageRequiresSSL && isSecureSSLChannel || !pageRequiresSSL && isSecureSSLChannel && isKeepSSLMode) {
    printDebugMessage("Page requires SSL = "+pageRequiresSSL+", channel is secure = "+isSecureSSLChannel+", is keep SSL = "+isKeepSSLMode);
    printDebugMessage("No protocol change required");
    // page requires SSL and SSL is not active. Switch to SSL.
    if (pageRequiresSSL && !isSecureSSLChannel) {
      printDebugMessage("Page requires SSL = "+pageRequiresSSL+", channel is secure = "+isSecureSSLChannel);
      printDebugMessage("Protocol change required to use https");
      switchToHttps(viewId);
    // switch to HTTP is page doesn't require SSL and channel isn't secure
    // and isKeepSSLMode is false
    if (!pageRequiresSSL && !isKeepSSLMode && isSecureSSLChannel) {
      printDebugMessage("Page requires SSL = "+pageRequiresSSL+", channel is secure = "+isSecureSSLChannel+", is keep SSL = "+isKeepSSLMode);
      printDebugMessage("Protocol change required to use http");
      switchToHttp(viewId);
    if (!pageRequiresSSL && !isSecureSSLChannel) {
      printDebugMessage("Page requires SSL = "+pageRequiresSSL+", channel is secure = "+isSecureSSLChannel);
      printDebugMessage("No protocol change required");
* Switches from https to http using a redirect call
* @param viewId
private void switchToHttp(String viewId) {
      FacesContext facesContext = FacesContext.getCurrentInstance();
      ExternalContext exctx = facesContext.getExternalContext();
      ViewHandler vh = facesContext.getApplication().getViewHandler();
      String pageURI = vh.getActionURL(FacesContext.getCurrentInstance(), viewId);
      //redirect to http URL
      String remoteHost = getHostNameFromRequest();
      printDebugMessage("Switch to http on host "+ remoteHost);
      try {
          String port = httpPort.equalsIgnoreCase("80") ? "" : ":" + httpPort;
          String url = "http://" + remoteHost + port + pageURI;
          printDebugMessage("Redirecting to http URL "+ url);
          //TODO check request Map
           this.printDebugMessage(" Content size of RequestMap before redirect "+exctx.getRequestMap().size());
          exctx.redirect(url);
      } catch (IOException e) {
          printDebugMessage("Redirect to http port failed "+ e.getMessage());
* switches to https using a redirect call
* @param viewId
private void switchToHttps(String viewId) {
      FacesContext facesContext = FacesContext.getCurrentInstance();
      ExternalContext exctx = facesContext.getExternalContext();
      ViewHandler vh = facesContext.getApplication().getViewHandler();
      String pageURI = vh.getActionURL(FacesContext.getCurrentInstance(), viewId);
      //redirect to https URL
      String remoteHost = getHostNameFromRequest();
      printDebugMessage("Switch to SLL/https on host "+ remoteHost);
      try {
          String port = httpsPort.equalsIgnoreCase("443") ? "" : ":" + httpsPort;
          String url = "https://" + remoteHost + port + pageURI;
          printDebugMessage("Redirecting to https URL "+ url);
          //TODO check request Map
          this.printDebugMessage(" Content of RequestMap before redirect "+exctx.getRequestMap().size());
          exctx.redirect(url);
      } catch (Exception e) {
          printDebugMessage("Redirect to http port failed "+ e.getMessage());
* @return the hostname of the page request
private String getHostNameFromRequest() {
      ExternalContext exctx = FacesContext.getCurrentInstance().getExternalContext();
      String requestUrlString = ((HttpServletRequest)exctx.getRequest()).getRequestURL().toString();
      URL requestUrl = null;
      try {
          requestUrl = new URL(requestUrlString);
      } catch (MalformedURLException e) {
          e.printStackTrace();
      String remoteHost = requestUrl.getHost();
      return remoteHost;
}If your container doesn't support session sharing between http and https then the session is renewed. In OC4J you will have to configure this.

Diff. between table and template in smartforms

hi there,
please tell me what the diff. between table and template options available in smartforms

HI
GOOD
TABLES=>
In forms of business procedures you usually want to list details such as open items of an invoice. You can use a Smart Form to display this data in a table. You can design the layout of the table independent of the number of lines it will contain. The size of the table depends on how much data the application program passes to the form at runtime (unlike with templates, where you specify the number of columns and lines explicitly). The table can cover one or more pages, depending on the number of lines. This is why you display tables in the main window.
TEMPLATES=>
Use node type Template to display a table whose layout and size (number of lines and columns) is determined before the runtime of the application program. For this reason, a template is also called a static table.
To create a template, define a table layout to determine the cell structure for each line. The cells are used to display the contents of the inferior nodes of the template node. This allows you to position text and a graphic side by side (see Displaying Graphics in Templates).
The template node is also suited for label printing.

Whats the diff between express and pro??

Just wondering what the main diff between the two are. I've used pro at school, but cant afford to get it at home. Will i still be able to use the same audio instruments like the same synths and plug ins??? Also, would i be able to run the program on a mac mini (top of the line)?

Matt Mac 63, "Whats the diff between express and pro??" #5, 10:33pm Oct 18, 2005 CDT
All I was saying is that if a person can afford to get Pro, they definitely should. The difference in features adds up to at least the difference in price, if not very much more.
Having said that, Express is good value compared to most other DAW software at that pricepoint, but it is only intended as a 'Lite' version.
Some examples, off the top of my head, of differences not made really clear in the comparison list.
Input Objects:
In Pro you can use Input Objects to monitor incoming signal without rec-enabling a track. That doesn't sound much, on the face of it, but what it means is you can use external FX units (hardware) as inserts in tracks (or busses) just like plugins, and bounce them with the mix. it also means you acn monitor what you are playing into Logic Pro with plugin FX applied, but record dry so you can hear your guitar with the reverb, or whatever, but still have the recorded dry signal so you can change the FX settings later.
Pro has some very handy environment objects. The main one being the Trabsformer object. But also another extremely useful object is TouchTracks.
If you've ever played with Ableton Live you would have noticed you can triger clips with the keyboard in all different ways (loop, gate loop, one shot etc.) Well TouchTracks does that with MIDI regions.(I have a feeling that feature in Live was modeled after Logic's TouchTracks' as it is incredibly similar.)
They are only a few examples of a whole range of differences. If all the differences were itemized in the 'comparison chart' it would be about 3 pages long.
All I am saying is, don't take the comparison chart as the definitive list of differences.
yes, Express is a good basic tool and you can do a lot with it, with some imagination.
The SOS author's claim that:
you're paying less than a third of the price of Logic Pro and getting over 90 percent of the functionality."
is not true in totality.
It may be true to someone who has never dabbled in audio software before, because it takes literally years to become fully conversant with every function in Logic Pro, and no-one uses absolutely everything.
But for serious users, who have big demands, in my opinion, Express is less than 30% of Pro's functionality.

=========================
what is diff between billing and invoice?
From the help for cash order, it says that the invoice will print immediately after order created, the billing will be done seperately by transaction after delivery. Can anyone explain more detail.
=================
based on ur query.. Billing and Invoice are one and the same.. the difference is that in general business terminology Billing means the process of crediting the customer to the certain sum of money either by cash or credit, for the goods or services purchased by him... this process consists of many other documents like credit note, debit note, invoice, etc.
Invoice is the Printed format of the Bill ie, the sum of amount the customer is credited is made available in the printiable format....
dont get confused by the Billing and Invoice words.. in simple way invoice is one of the documents generated during the billing process.. Billing is a process which consists of various different documents which are generated depending on the business requirements...
Reward if USeful
Thanx & regards.

Diff Between Interfaces and API

Hi to all.
Can anybody tell me , What is the basic diff between API and Interfaces ?
Thanks in advance

Hi Lalit,
Both place validation will happen. In Interface table as well as in API.
The difference you can say..for interface you have to load the data in and invoke the import program by which it will populate data in oracle apps base table. So you have to write some DML.
While in API you can simply use PLSQL record type and using that invoke API by which it will populate record in oracle apps base table.
Keep in mind both ways the validation happens. It is just the approach and some part is just for legacy data conversion.
