Error 66 and error 18500 using HTTP GET control: SOLVED

Hello, I'm new as a member and as a LabView user but I spent many hours trying to get the URL_Get_HTTP vi to play nicely with my code, and as a courtesy I thought I would post the problems I was having and the resolution(s).
First of all, I was receiving an Error 66 every time I would attempt to make a connection. This implies that the server terminated the connection, but I knew that this was not the case as I could connect just fine in other manners (browsers, PHP, etc)...
1) I changed the "bytes to read" input of the "TCP Read" control residing in the middle of the "TCP Buffered Read.vi" from a constant of 1024 to 1. I have not confirmed that this step is required and you may want to apply step #2 on its own.
2) I stripped the Error 66 from the "URL Get HTTP Document.vi" inbetween the "TCP Buffered Read" control and the "TCP Read Stream" control. You can do this by disconnecting the wire, adding a "Clear Error" control on that wire, or perhaps least offensively using my attached control which selectively removes only Error 66. You should review my control before using it, as I am a new LabView user! If you think this is "bad form" to strip and ignore an error I would completely agree, but I'm going to classify this as a bug in the control itself, and would also point out that the 4th post of the following thread concluded the same thing.
http://forums.ni.com/t5/LabVIEW/Can-t-read-page-containing-XML-using-GET-HTTP-Document/m-p/1191803#M...
3) To this point the Error 66 is no longer showing up, but now Error 18500 is, which is labeled as "undocumented" which was not very helpful. Most people will probably not suffer from this problem, but ultimately the cause was that my URL string ended in a carriage return. The HTTP control does not appreciate this in any way, and a simple Trim on the string before sending it resolved this issue.
Anyway, good luck!

Try to send some valid data in COMP_CODE.
It seems that SAP is returning some reply which is not fitting your response Schema.
SAP Call is made and problem is in generating response document.
Use the design console to test the view again. and try to see the XML resquest document and response document. Compare your request xml with that in design console.

Retrieve data from a non-peoplesoft application using HTTP Get

I need to retrieve data from a non-peoplesoft application. They want us to submit a HTTP GET request to their URL with a series of parameters. I am thinking about using HTTP Targert connector to accomplish this. Does anyone have sample peoplecode?
Currently we are on 8.51.10 Tools...
If there is any better way .. please let me know ..

I have used HTTP Get to get XML file from a government sanction list by hitting URL http://www.treasury.gov/ofac/downloads/sdn.xml
There is a delivered PS program that does that for vendor sanctions. I had to get the online setup correctly by creating a new custom Node with HTTP Target Connector. The program name is BSP_IMPORT. The below code is responsible for the calling the node and retrieving the data. Play around with the code below see if you can get it to meet your needs.
BSP_IMPORT_AET.BANKNODE.Value is just the custom external code that I created.

Is it possible to use HTTP GET navigation links?

Hi,
I'm learing JSF technology, I found it very powerful.
But I'm not able to understand how generate navigation links that use HTTP GET method. Do anyone Help me?
It seems impossilbe, but I don't want believe that it is true.
Building a web site using only HTTP POST methods is out of the W3C for Web Site suggestions.
A "good" serach engine for example dosen't take in cosideration HTTP POST Links.
I hope that someone tell me how generate using JSF HTTP GET links for navigation.
Bye

Balusc, thanks for you help.
The blog is very good!
I make help classe (FacesUtils) who you show in blog, but not find the property on request context map, but I use the param variable on faces-config.xml and Request Managed Bean and all work fine.
thanks.
I'm wrong where I think the Request Managed Bean is create for each request on all pages, the Request Managed Bean is create only on requeste page reference its.
Parte of my faces-config where I put the Request Managed Bean:
<managed-bean>
          <managed-bean-name>uuidParamManager</managed-bean-name>
          <managed-bean-class>
               br.srv.full.virtual.managers.request.UUIDParamManager

          <managed-bean-scope>request</managed-bean-scope>
               <managed-property>
               <property-name>loginManager</property-name>
               <property-class>
                    br.srv.full.virtual.managers.LoginManager

               <value>#{param.UUID}</value>
          </managed-property>
     </managed-bean>Where UUIDParamManager is create on request its receive first the LoginManager Instance, and later its receive the UUID param.
I put the prototype of project on virtual.full.srv.br.

No, it is asking you to register with your Amazon user id and password. Your Apple ID won't work.

Retrieving image using HTTP GET method?

I want to send a image to a client browser. My servlet's HTML response to the client browser contains the <img src="..."> tag. The client browser uses the HTTP GET method to call my servlet's DoGet method, and I must transfer the desired image to the client browser in this DoGet method at servlet. Now, the problem is that, what should be the source URL in the image(img) tag that is present in my servlet response to client?
For eg: the img tag should be like this
<img src="http://<hostname>:<portname>/<servletname>/...?[var1=value1]">
Now at the ellipsis that you see in the above source URI, I want to write the type of image file (something.jpg) ,so the browser knows what kind of image file it is.
To sum it up...how to get the image using DoGet method and <img src="...">
Regards,
Amit

To give you a better idea on what's happening, read the RFC:
(HTTP/1.0) http://ftp.ics.uci.edu/pub/ietf/http/rfc1945.html
(HTTP/1.1 - compressed data)
http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
If you for example execute the command by telnetting to port 80 on a server:
GET http://somewhere.com/some.jpg HTTP/1.0<cr>
<cr>You will get this header:
Trying 217.22.64.73...

The browser reads the header, and decides what to do with it, in combination with (X)HTML markup.

ACE keep probing real servers using "https get 302"

Hi all,
I got one problem with cisco ACE in my company. Currently, two ACE appliances are working as HA redundancy. Previously I enabled some https and http probing using get 302 for some servers and services. But then I was told to remove all https or http probing, and instead use tcp port 443 and 80. After that, one of the serverfarm (server groups) is receiving https get 302 and I already checked in the monitoring and see whether there's any https probing regarding the respected real servers. But I could not find any. Even I disable all probing to that serverfarm, all the server members still receiving https get 302. Is this behavior a bug?
The ACE version is A3(2.1). And the HA status is on standby cold. Can standby cold cause this kind of trouble?

Hi Daniel,
I just corrected the cert problem and made the state peer into standby hot. But still it still keep probing the get 302. And then I tried to restart both ACEs. The first step is to restart the second ACE (standby) and then switched over all context to the second one. The problem is that when I made the second one to be active, some services were not working, especially the ones with ssl terminated in ACE. I'm pretty sure that both ACEs were in sync.
Any idea what is the problem?

Sslv3 poodle vulnerability and sharepoint site using https

We have one web application accessible to users using HTTPS with a valid SSL from CA.

FIPS 140-2 is not supported by SharePoint and enforcing it will break SharePoint.

XMLHttpRequest crossdomain error when using restful GET glassfish

Hi,
I try to make a XMLHttpRequest call from my apache server to the apex listener under glassfish with a simple RESTFUL ressource named departement.
We use apache for static page and some php page. I put a Header set Access-Control-Allow-Origin * in my httpd-vhosts.conf to allow cross domain call.
When I make my call I get the following error:
XMLHttpRequest cannot load http://192.168.100.24:8080/apex/localite?departement=61. Origin http://sirius:8888 is not allowed by Access-Control-Allow-Origin.
Of course I could put allow my static page under the same virtual server of GlassFish and this case have only one domain, but it has many other constraints.
In my test I use the EXTJS class in the following manner
var store = Ext.create('Ext.data.Store', {
autoLoad: true,
autoSync: true,
model: 'Departement',
proxy: {
               limitParam: undefined,
               startParam: undefined,
               pageParam: undefined,
               noCache: false,
               api: {
                    create : 'http://192.168.100.24:8080/apex/localite?departement=61',
                    read : 'http://192.168.100.24:8080/apex/localite?departement=61',
                    update : 'http://192.168.100.24:8080/apex/localite/inse'//,
                    //destroy : '/controller/destroy_action'
type: 'rest',
url: 'http://192.168.100.24:8080/apex/localite?departement=61',
reader: {
type: 'json',
root: 'items'
writer: {
type: 'json'
Any help would be welcome. If anyone had an example of using ExtJS form with RESTful apex listener it would be a dream !
Frédéric

Hi Frédéric,
though I can't help you with providing an example right now, I know that you need more headers for Ajax requests. It should (at least) be the following three:
1. Access-Control-Allow-Origin *
# which you've already got, though I won't use "*" for security reasons
2. Access-Control-Allow-Methods POST, GET, OPTIONS, STATUS
# perhaps additional methods are needed depending on your requests
3. Access-Control-Allow-Headers *
# where you might want to tweak the "*" as well and limit it to the ones you actually need.
There is a comprehensive article on that on [url https://developer.mozilla.org/en/http_access_control]Mozilla Developer Network.
I hope this helps you solve your problem.

Remote handle caching error when using HTTP session replication

          Using WL 7.0 Sp2 on Solaris, deployed apllication on a 2 instance wide cluster.Code
          attached -
          unzip testapp.zip to find a test.jar which is the stateless sesion ejb and test.war
          which is the applicaiton.
          I have this class - TestDelegate that looks up a stateless session EJB(TestEJB),
          and puts the remote handle as a member variable(Test bean).Test.jsp instantiates
          this delegate(TestDelegate ), and then via setAttribute puts the TestDelegate
          in the HTTPSession.Then it calls a couple of methods via the TestDelegate which
          has the remote handle of the TestEJB.
          Scenario 1 : We deploy the WAR on cluster A which is 2 instance wide,we deploy
          the TestEJB on
          cluster B, which is also 2 instance wide. All works fine, the delegate is able
          to lookup EJB and
          can add the remote handle as a member variable.
          Scenario 2: We deploy the WAR on cluster A which is 2 instance wide,we deploy
          the TestEJB on
          cluster B, which is also 2 instance wide. This time we put a weblogic.xml in the
          WAR which has tag for in-memory session replication.This time we get class cast
          exception for the same sequence that we have above.

To see the list of session IDs in the cache you can iterate over the keys of the cache returned from the following code:
NamedCache cacheCatalog = CacheFactory.getReplicatedCacheService("$FilterService$").ensureCache("CoherenceSession.CATALOG", getClass().getClassLoader());Then to see the contents of a session you can take a look a the cache returned from the following code:
String sId = // keys from cacheCatalog
NamedCache cacheDetails = cacheCatalog.getCacheService().ensureCache(sId, getClass().getClassLoader());Hope this helps.

How to set default value and after that , use it as control

Hello,
Currently i am making motor driver from labview, and i am facing one problem.
When i connect to my board via labview, it will relay last position to global variable. After that, i have to go to loop, where i can send back modified position to my motor control board
In short, i have to control number, but that number default value should be writtem by another function when i start vi.
any ideas how to do it ?

R/3 HTTP GET to external supplier - what are the options

Hello all
Our scenario is that we have to connect to an external supplier using HTTP GET to get our order responses in the return structure. I was wondering what the best/easiest way is to do this.
We cannot use the HTTP adapter since that only supports HTTP-POST. Additionally the RFC that lies behind it does not allow query strings in the definition, something we need to use.
we could make use of the HTTP_GET function module in the SFTP function group but how to do it then?
-we cannot create an abap proxy for this since the outbound WSDL contains invalid keywords (choice keyword not supported)
-we probably could use BPM that calls the HTTP_GET.
-we could write an ABAP that calls the HTTP_GET and puts the output into a directory where XI can pick it up.
-I also read that you could write a small java function that does the HTTP_GET . But i have no experience with this.
So what is the best option to accomplish this?
thanks
Tom

From SP15 you may use Adapter-Specific Message Attributes.
To evaluate adapter attributes in the message header of the XI message, set the Use Adapter-Specific Message Attributes indicator.
     If you want missing message attributes to trigger an error message, set the Fail If Adapter-Specific Message Attributes Missing indicator. If the indicator is set and the header for adapter-specific message attributes or one of the set attributes is missing from the message, this leads to a system error (red flag).
If you do not set the indicator, and message attributes are missing, the adapter accesses information from the adapter configuration.
     If you want to use an HTTP destination or URL set by the mapping, set the URL or HTTP Destination indicator. (The indicator displayed depends on the Addressing Type you selected above). If you set the indicator, the URL or HTTP destination set dynamically is called by HTTP.
If the message header does not contain the URL or the HTTP destination, and you have set the Fail If Adapter-Specific Message Attributes Missing indicator, the XI message is set to status System Error. If you do not set the indicator, the URL or HTTP destination defined statically in the communication channel is used.
     If you want to use HTTP Header Fields, set the indicator and enter the fields in Field 1 to Field 6. The fields are embedded in the HTTP request under the names you enter here.
The technical names of the fields are HeaderFieldOne, .... HeaderFieldSix.
     If you want to use URL Parameters, set the indicator and enter the parameters in the fields Parameter 1 to Parameter 6. The parameters are embedded in the HTTP request under the names you enter here.
The technical names of the fields are URLParamOne, c, URLParamSix.
The attribute namespace for the adapter is http://sap.com/xi/XI/System/HTTP.

HANDLING HTTP "GET" IN SENDER ADAPTER

Hi,
I have a Scenario where I have to use HTTP GET Adapter to get data from a website daily to PI and Post the data from PI to SAP ECC.On the receiver end Idoc is being used.I need help on what to use (From sdn I came to know that Java Proxy or Adapter Module can be used ) and how to configure the sender adapter in this scenario.In case of Adpater module the steps needed to configure the scenario would be helpful.In case of Java Proxy sample code that would suit the scenario would be appreciated.

Only 7.3 version (Latest) supports HTTP GET method. All previous versions support only POST.
In your case java proxy is better choice.
Refer these standard links.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/7d4db211-0d01-0010-1e8e-9b07fc2113ab?quicklink=index&overridelayout=true
http://wiki.sdn.sap.com/wiki/display/Java/JavaProxyChangesinPI7.1fromPI7.0
http://help.sap.com/saphelp_nwesrce/helpdata/en/86/58cd3b11571962e10000000a11402f/content.htm
Basically you have to create java proxy for the outbound (sender) interface and use those proxy(stub) objects to code in java. Refer sender java proxy in the above link.

HTTP GET for sender adapter possible ?

I have to get XML-messages from third party webservice. I should use HTTP GET to get the data but is this possible in XI ? I mean like RFC->XI->HTTP(GET) and I would process the response from HTTP GET call.

Hi Jari,
For getting response from web service, you should use SOAP adapter.
Anyways,if it for web application, you can use HTTP get in XI for synchronous communication.
Have a look at these blogs for details -

Newbie: does Oracle BPEL Process Manager support http-get/post binding?

Hi all,
i'm a newbie in using bpel4ws. Two things i must know before using the Oracle BPEL Process Manager:
1. Does the manager support the sub-specification bpel4ws?
2. I want to orchestrate some services which aren't binded using http-SOAP or rpc. They are binded using http-GET and http-POST. Does the manager support these bindings too?

Hi Clemens,
thanks for answering.
Ähhm... as i told you, i'm newbie here. I searched for the content of
samples/tutorials/702.bindings/http
But i'm afraid i don't know where to start. Its no URL and i didn't find the source of this path. Can you add the full URL or tell me how to get to the source of these samples?
thanks
