Strange behaviour when passing many input parameters to web service

Hello!!!
I developed a web service with 52 input parameters using tomcat+axis!
While testing it in my development enviroment everything was working fine
(LAN consisted of three windows 2000 server machines!!!)
When i deployed it in my customer enviroment (VPN with 200 isdn connections) i get a very strange error:
AxisFault
faultCode: {http://xml.apache.org/axis/}HTTP
faultSubcode:
faultString: (0)null
faultActor:
faultNode:
faultDetail:
{}string: return code: 0
(0)null
when i used tcptracer in order to understand what is going on,
I realised that the error occurs when the http request is more than 1350 bytes.
Can someone explain this behaviour?
thanks in advance!

Hi Sarantos,
I think, there is nothing wrong in the axis engine nor the http request limits as you said. I tried the same passing a 60 kb String as an argument to an operation , getting the results perfectly.
So problem could be with the method capacity size of your implementation. (I think default it is 64kb)

Strange behaviour when looping MIDI

Hi,
I encounter a strange behaviour when looping MIDI:
1) Created a new MIDI track
2) Recorded two bars of MIDI drum track (e.g. just a bass drum with Indie Kit Live) via my EDIROL and MIDI piano.
3) played it back: works
4) checked the "Loop" box
5) played it back: after the 4th repeat the drum pattern changes. either it misses two beats or does not play the bass drum but the hihat for two beats.
I'm using Logic Pro 8.
Can someone tell me what's going on and how this can be resolved?
Also on some occasions I have the following behaviour:
1) Recorded MIDI in loop mode (a few takes).
2) Played it back: Did not produce any sound.
3) Tried a different take from the take folder: Did not produce any sound.
4) Tried to mute/unmute track and different take from the folder: Did not produce any sound.
5) Tried to MIDI mute/unmute different takes from the folder: Did not produce any sound.
6) Closed/reopened project and MIDI unmuted the take: Played fine.
Thanks a lot for some help with those two problems.
Alex

Did not happen again in Logic 9 and after starting a fresh project.

How to Specify Metadata When Adding Content Using iTunes U Web Service?

I've been developing Java applications using iTunes U Web service and uploaded content to iTunes U site using iTunes U Web service without problem. Now I want to add metadata fields (name, artist name, album name, etc.) for the tracks I uploaded. It seems to me that "AddTrack" will do. So I tested it but it neither adds a track under the specified group nor updates metadata fields for an existing track. It turned out "MergeTrack" actually updates metadata fields for an existing track. So is there any way to specify metadata at the time of adding content using iTunes U Web service? And what exactly does AddTrack do? This is all about contents hosted by iTunes U site and no RSS is involved.
I'm referring to the "AddTrack" method in iTunes U Web service:
http://deimos.apple.com/rsrc/doc/iTunesUAdministrationGuide/iTunesUWebServices/c hapter18_section_21.html#//appleref/doc/uid/AdminGuide-CH13-SW26

Thanks for all the replies. My question is whether there is any way to specify metadata WHEN adding content using iTunes U Web service. Specifying metadata AFTER adding content can be achieved by MergeTrack (weird naming) and it does work.
As for setting track level meta-data in the media file and then upload it, there're several reasons against that, among which are:
1. Some track metadata are context-dependent. A video about buildings on Michigan Ave in Chicago can be track #2 in a history course and described as "historic view of the Magnificent Mile", but the same media can also be track #5 in a landscape design course and described as something like "contemporary architecture". Setting these metadata in the media file itself is not the preferred way to do it since it implies maintaining a version of the same media for any course/group it gets uploaded to.
2. Setting metadata in a location separate from the media file helps track the metadata change and search for media without digging into the media itself.
3. If MergeTrack "updates" metadata, there got to be some other method that "creates" metadata - that's what a well-designed API should look like. And setting metadata in the media file is not an equivalent to a "create metadata" method call. In rickwolf's term, that implicit AddTrack should actually be made explicit so the party uploading content can explicitly specify metadata instead of having iTunes U extract metadata from the media.
It is still not clear what "AddTrack" does exactly, maybe rickwolf is right - it's only relevant to tracks created through RSS.
So it seems to me there is no other way to specify metadata WHEN adding content using iTunes U Web service than setting metadata in the media file. To me it is more like a design flaw.

Strange behaviour when running parameterized test

Hello,
I am using Flex 4.5 and FlexUnit 4.1 inside of the Flashdevelop IDE and I am experiencing some very strange behaviour.
If I have 5 parameters to my test the test runs fine. When I add a sixth parameter of the type Array, I get the following error:
"TypeError: Error #1009: Cannot access a property or method of a null object reference."
Please see below for my example code.
The following parameterized test case runs without a problem:
package {
    import org.flexunit.runners.Parameterized;
    [RunWith('org.flexunit.runners.Parameterized')]
    public class ParameterizedTest {
        [Parameters]
        public static var testData:Array = [
            [1,1,new Array(),1,1]
        public function ParameterizedTest(
            param1:uint,
            param2:uint,
            param3:Array,
            param4:uint,
            param5:uint
        ):void {
        [Test]
        public function testOne():void {
            // Test to go here.
When I add an Array as the sixth parameter :
package {
    import org.flexunit.runners.Parameterized;
    [RunWith('org.flexunit.runners.Parameterized')]
    public class ParameterizedTest {
        [Parameters]
        public static var testData:Array = [
            [1,1,new Array(),1,1,new Array()]
        public function ParameterizedTest(
            param1:uint,
            param2:uint,
            param3:Array,
            param4:uint,
            param5:uint,
            param6:Array
        ):void {
        [Test]
        public function testOne():void {
            // Test to go here.
I get this error :

Can anyone help me?

Actually, I do see what's wrong.
When you call a method in the ActionScript universe, you can can usually do a function.apply() and pass it a variable number of args. Unfortunately, constructors are the one type of method where this doesn't work. You can't actually do an apply() so we have to fake it by having a map of static functions which each know how to apply a given number of arguments to the constructor. There is a check in the code that tests if the number of arguments you have exceeds what our static map knows how to apply.
It looks like that check should have thrown the error:
throw new ArgumentError("Sorry, we can't support constructors with more than " + argMap.length + " args out of the box... yes, its dumb, take a look at Constructor.as to modify on your own");
It didn't and I am guessing its because there is a border condition here. So, what happening is that we only support up to 5 arguments right now. That number is arbitrary. When it was written it just seemed like a reasonable number, however, this class was written before Parameterized testing was introduced.
Your three choices right now would be to use the TestNG style of Parameterized testing, which uses functions and not constructor args so it will not suffer this same fate, change the code and compile flexunit for yourself, or we could put a patched Constructor class in your project which fixes it. Longer term, I would like you to file a bug that we should increase the number to 10 or some other quasi-reasonable number. We will never be able to support an infinite number and we will always need to pick som arbitrary line in the sand. It just seems our line should be farther out.

How to bind/pass multiple input parameters to sql query in BPEL Process

Hi,
I have a requirement to invoke a query on a database table to fetch the records based on the few input values or bind variables?
I have created a Partner link using the DBAdapter service and have used custom SQL, how can i bind and pass multiple bind/input parameters for these queries.
foreg: if i have to query employee records based on name , desgination and age, these three params would be my input parameter that i will pass when i invoke the BPEL process, bow how can i pass these parameters to the partner link using DBADAPTER service.
Please help
Regards

If the parameter-value is not known beforehand and cannot be determined based on the process instance data at that time, there are 2 options. Either invoke the PL/SQL procedure you named using a DB adapter service to get the value and pass it to the other DB adapter service. Or create a single service (e.g. PL/SQL procedure) that determines the parameter value, executes the query and returns the result. However, this is more a design issue. Does it makes sense to combine these actions in a separate service and use it or are these actions not related? You furthermore state that additional (DB adapter) services make the process heavier. Do you have strict requirements on the time process-instances may run or other such requirements? If not, I think the design-choice on whether combining these actions in a single service should have more priority.

Create an API to Launch an LabVIEW Built Executable and Pass it Input Parameters

Hello,
I'm looking for a way to create an API to Launch/Close an executable, created with LabVIEW, which in additional to Launching/Closing tht executable, will also allow me to pass input parameters.
To give you some background, I'm working on a logging utility, basically a background dameon, which I currently have implemented as a LabVIEW packed library and my API is a few VIs to launch that daemon and pass it a filename and a logging rate. Functionally it works just fine however is executes within LabVIEW not as an independent process. So instead of using a packed library, I would like to compile my logging daemon down to an executable but I still need a way to launch it and pass it parameters from an external application (such as Teststand).
I know you can launch executables and pass parameters using windows command lines, but I'm wondering if there is a more direct method such as a DLL that I could call in Teststand? Thanks.
Post CLD and when I'm a CLA when someone asks who I am, I can spin around in my chair and say "I am... the architect."

When Teststand Launches the Logger, it does so by opening a reference to the logger daemon using the "Open VI Reference" primitive and then it launches an instance of the dameon using the "Start Asynchronous Call" node.
This currently, launches the logger within labview not teststand. If I were to directly call the logger daemon VI itself as a step in TestStand, then it could run in a new teststand thread. At that point I would need a way to stop that logger which I should be able to do by storing a reference to its control queue within the teststand thread that it is running in. Since teststand let's you specify VI execution in the runtime engine instead of LabVIEW that might do the job.
The one catch is once the sequence completes, the logger does some cleanup, post processing, etc that depending on the amount of data captured can take some time so if a set of sequences needs to be executed, this could hang up teststand until that post processing is completed. That is one reason why I wanted it to execute outside of testtand so that additonal sequences could continue to run while the daemon finishes up in the background.
But, it's something I'll have to look into.

Strange behaviour when placing text frame on top of image

Hi,
Win XP, FM 8.04
I have a front cover that consists of a TIF image that bleeds off the page. On top of that image I want to put a text frame with the book title.
The strange thing is that when I create the text frame and use the toolbar buttons to nudge it down on the page, the text (but not the frame) suddenly jumps to a totally different place way down on the page, despite only nudging it, say, 10 mm.
Any ideas why this is happening?
/Mats

Hi,
Partly solved:
After some tests, it seems FM does not like when you try to move a text frame over a transparent area in an image. The image in question was made by importing a PDF into Photoshop, then saving as TIF. Since the PDF contained an area that was had full transparency in InDesign (i.e. "Paper"), that area was also in the TIF image.
The strange behaviour starts exactly at the border where the transparency starts. In non-transparent areas, there is no problem.
Seems like a bug.

Strange behaviour when setting client_info and module in v$session

Hello,
I've tried to set the CLIENT_INFO field in V$SESSION using DBMS_APPLICATION_INFO.SET_CLIENT_INFO but found a strange behaviour.
Normally the forms modules seems to set the field MODULE in V$SESSION to its name. If I use DBMS_APPLICATION_INFO.SET_CLIENT_INFO the CLIENT_INFO field is set correctly but the MODULE field is set to 'frmweb.exe' instead of the forms modules name.
I also tried to set the MODULE using DBMS_APPLICATION_INFO.SET_MODULE but then strangely the MODULE and MODULE_HASH field of the original frmweb.exe (the main applet?) entry and the entry for the forms module were the same (set to the new module name). From now on every newly opened module had 'frmweb.exe' as the module entry until I closed the forms application.
Example:
Entries in V$SESSION:
-- After start of forms application there is only one entry for the process:
PROCESS           MODULE            MODULE_HASH            CLIENT_INFO
1596:7204         frmweb.exe        854945150
-- When a new forms module is opened it looks like this:
PROCESS           MODULE            MODULE_HASH            CLIENT_INFO
1596:7204         frmweb.exe        854945150
1596:7204         my_module         1929284615
-- When the modified forms module that sets the client_info/module is opened this happens:

The following code is responsible for the changes of CLIENT_INFO and MODULE:
    -- get client info
    client_info :=
        webutil_clientinfo.get_ip_address
        || ' (' ||
        webutil_clientinfo.get_user_name
        || ')'

    DBMS_APPLICATION_INFO.SET_CLIENT_INFO(client_info);
    -- get module (set action to '')
    DBMS_APPLICATION_INFO.SET_MODULE(name_in('system.current_form'),''); I really don't understand, why it does not work properly.
Any help is appreciated!
Thanks in advance.

This was an application module pooling, activation / passivation issue.
After view objects had been set-up correctly, the problem disappeared.

Strange behaviour when using connection pooling with proxy authentication

All
I have developed an ASP.NET 1.1 Web application that uses ODP.NET 9.2.0.4 accessing Oracle Database 8i (which is to be upgraded to 10g in the coming months). I have enabled connection pooling and implemented proxy authentication.
I am observing a strange behaviour in the live environment. If two users (User 1 and User 2) are executing SQL statements at the same time (concurrent threads in IIS), the following is occurring:
* User 1 opens a new connection, executes a SELECT statement, and closes this connection. The audit log, which uses the USER function, shows User 1 executed this statement.
* User 2 opens the same connection (before it is released to the connection pool?), excutes an INSERT statement, and closes this connection. The audit log shows User 1, not User 2, executed this statement.
Is this a known issue when using connection pooling with proxy authentication? I appreciate your help.
Regards,
Chris

Hi Chris,
I tried to reproduce your complaint, but was unable to. I didnt use auditting however, just a series of "select user from dual" with proxy authentication. You might want to see if you can put together a small complete testcase for this and open a sr with support.

Queue with callback function - strange behaviour when using max_retries

Hi,
I hope someone can tell me what is wrong or can explain the following strange behaviour to me.
I am using one queue with a registered callback function. To test the behavoiur in case of an error I tested different settings, with or without explicit exception queue and with or without parameter max_retries.
Database Version is 11.2.0.2.   Enterprise Edition
I enqueue 10 messages in a loop.
I define no exception queue and do not set max_retries
==> all messages stay in the queuetable with q_name = AQ$_... (implicit exception queue) and retry_count = 5
I define no exception queue and set max_retries = 4
==> 1 message stays in the queuetable with q_name = AQ$_... (implicit exception queue) and retry_count = 4
       9 messages stay in the queuetable with q_name = nomal queue name and retry_count = 0
I define an exception queue and set max_retries = 4
==> 1 message is transfered to the Exception Queuetable with retry_count = 4
       9 messages stay in the normal Queuetable and retry_count = 0
I define an exception queue and do not set max_retries
==> all 10 messages are transferred to the Exception Queuetable with retry_count = 5
I have no explanation for the behaviour in case 2 and case 3.
To create the queue and the callback I use this code (reduced to minimum):
begin
   DBMS_AQADM.CREATE_QUEUE_TABLE(Queue_table        => 'TESTUSER.TEST_TABELLE'
                               , Queue_payload_type => 'SYS.AQ$_JMS_TEXT_MESSAGE'
                               , sort_list          => 'enq_time'

Using interfaces as input or output parameters in web service

hello
I searched the web looking for a clear answer wether my web service
can return or receive an interface (when using rpc), but i haven't got one.
My web application methods were designed to return interfaces, so now
i'm having a problem creating web services from those methods.
Do i have to change my application to fit the web services spec?
Amir

Hello,
If your backend components use non-built-in data types as parameters or
return values, you must create the Java code of the data type and then
create or generate the serialization class that converts the data
between XML and Java. See:
http://edocs.bea.com/wls/docs81/webserv/implement.html#1068229
The supported Java non-built-in data types are listed here:
http://edocs.bea.com/wls/docs81/webserv/assemble.html#1068595
If you have a short example would be helpful to see what you are
building.
Regards,
Bruce

Error passing bool/categorical parameter into web service

I am working on publishing a web service to produce a prediction based on a model. One of my parameters is whether or not a given day is a holiday, which was a boolean (TRUE / FALSE) that was calculated during an R script. When I preview the
output of my input data, I see lowercase "true" and "false". When I try to pass this into the web service, I get the following error.
InputParseError: Parsing of input vector failed. Verify the input vector has the correct number of columns and data types. Additional details: Value "bool" is not defined in enum. Line 1, position 2167.., Error code: BadArgument, Http status code:
400, Request id: 338eb834-b195-4a09-b6b2-47a0b91e80f1, Timestamp: Fri, 23 Jan 2015 20:51:09 GMT
I have tried passing in true, 1, TRUE.
Does anyone know how I can successfully pass in a value for this parameter to get the service to execute?
Thanks,
Jeff

Hello Jeff,
This is the error observed in our log:
Code: InputParseError, Target: ClientID,Location,Procedure,Month,DayOfWeek,Holiday, Message: Parsing of
input vector failed. Verify the input vector has the correct number of columns and data types. Additional details: Value "bool" is not defined in enum
You have tried to pass "true"/"TRUE"/1 as input value for "Holiday" right? Do you mind sending us more information to help troubleshoot? I'd like to request 1) your sample R code 2) your sample input. Could you please
send to my email address?
Thanks

Trying to pass xml data to a web service

I'm working on an Apex application that is required to pass data to a web service for loading into another (non Oracle) system. The web service expects two stings as input, the first string is simply an ID, the second string is an xml document. I generate an xml 'string' using PL/SQL in an on-submit process prior to invoking the web service. If I pass regular text for the second parameter, the web service returns an error message which is stored in the response collection and displayed on the page as expected. When I pass the the xml data, I get a no data found error and the response collection is empty. I have tried this in our development environment on Apex 3.1.2 (database version 10.2). I also tried this on our Apex 4.0.2 sandbox (with the same Oracle 10.2 database). I have found that once I have nested xml, I get the no data found message, if I pass partial xml data, I get the error response from the web service. Perhaps I am not generating the xml correctly to pass to the web service (this only just occurred to me as I write this)? Or is there an issue passing xml data from Apex to the web service? Any help will be greatly appreciated! here is the code I use to generate the xml string:

The user reviews the data in a sql report region. When the use clicks on the Upload (SUBMIT) button, the xml string is generated first and then the web service is invoked. I have tried passing a simple string as the second parameter ("dummydata") and partial data in the xml string ("<sendingPerson>Test, Christine</sendingPerson>") the web service returns this error in both cases:
Error[Validate Data]: (XML) = Data at the root level is invalid. Line 1, position 1.. Cannot validate the XML! Data Exchange not accepted!Once I pass the entire xml string above, I get an Oracle-01403: no data found error. I have opened the web service in IE and pasted my xml input string and received a valid, verified result, so I am sure that the generated xml is correct. I have spoken with the web service developer; there are no log entries created by the web service when I submit the full xml string, so I suspect the failure is in the Apex application.
Thanks,
Christine
I should add that once I have nested tags in the xml, I get the Oracle no data found error ("<header xmlns=""> <stdXmlVer>2.0</stdXmlVer> <sendingUnit>10</sendingUnit> </header>"). I f I do not have nested tags in the xml ("<notification>[email protected]</notification> <creationDate>2011-12-20</creationDate>"), I get the web service response (error).

Ok, I think I'm getting closer to thinking this all the way through. When I have used clobs in the past, I've always used the DBMS_CLOB package. I use this to create a temp clob and then make the above calls. I had to go find an example in my own code to remember all of this. So, here is another suggestion... feel free to disregard all the previous code snippets..

end;This code will use the Database to construct your clob and then convert it back to a varchar2 for output to your webservice. This makes more sense to me now and hopefully you can follow what the process is doing.
You don't technically need the two varchar2(36767) variables. I used two for naming convention clarity sake. You could use just one multipurpose variable instead.
If you have any questions, just ask. I'll help if I can.

Problem in passing/returning objects over dynamic web service call

Hi Friends,
I am beginner in java web service.
Here is the problem I am facing when I pass/return user defined objects to remote web service method using dynamic we service call.
The client can call the remote web service method in 2 ways.
1. By generating client stubs using WSDL file
- In this case, I am able to pass/return the user defined objects to remote method without any issue only when the server side web services are deployed in any server(jboss)
- But in java 1.6 & above, the web services can be deployed without server using endpoint. In this case, I am not able to pass/return objects over web service calls.
2. Without generating client stubs (dynamic web service call)
- This will establish a connection at run time using the given WSDL file (I have attached the document). I have to form an XML(This will contain API name, arguments) string as input at run time
- In this case, it allows only string as argument while passing & returning.
Please let me know if you can help me on this.
Regards,
pani
