Down-/Upload files via Web Services using a NON-SAP system!?

Hello,
is it possible to down-/upload files via web services using a NON-SAP system!?
Regards,
Jens

Hi Jens,
I am not sure about your requirement here. What i could understand is that you want to check whether service could handle file processing?
1) Uploading file - You can build a Webservice which has import/export parameters as the file structures and implement the proxy class in such a way that the passed data is written to application server.
2) Downloading file - Same as uploading file, but the proxy class would have the code to extract data from the application server and pass them as output parameter.
Functionality of Non SAP system: The system which calls these services should be able to convert the output of proxy data into file in case of downloading the file and it should be able to convert the file data into export parameters in case of uploading file.
Hope this helps.

How to create a proxy to retrieve the xml file from web services

Hi Every one,
We have a requirment where we receive a xml file from Kenexa, a third party HR tool using a middleware tool. from SAP side We have to create a proxy to retrieve the xml file from web services by initiating call through middleware tool i used earlier.
these are the steps i intend to follow to accomlish the requirement.
1) middleware tool has to initiate the call to kenexa web services to receive the xml file when it is available.
2) On SAP we need to create a ABAP Proxy service provider to middleware where this file can be received.
Can any one guide me how i can create a proxy to retrieve the xml file from web services by initiating call through other middlewre (its not PI).
Any help would be really great, i am not a ABAP developer, so please help me with this. Thanks.

Thank for reply.
The computers are in different locations, but yes it's possible, the users in this enviroment are all local administrator of the machines, and we can distribute the script centrally from the DC automatically
Acrobat use Java, right? I'm not so expert in java, but something about it could not be so difficult to manage.
Do you know some place where i can get some info about JS and acrobat?

Sending audio files through web service

Hi,
How can we send audio (mp3,wmv) files through web services ? i have tried making a byte array of the file and then sending the byte array through the web service, but it give OutOfMemory error. so is there any better and practical way of doing it ?

Just read catalina.bat and find where $JAVA command is called, for NT it should be "%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% "
"%_EXECJAVA% is java
%JAVA_OPTS% and %CATALINA_OPTS% are enviroment parameter for java command. Just added one of them in your case.
By the way, " i am using a HP PDA on the client side, so i cannot increase the JVM heap size there", you should info. the client, otherwise the client may be get "out of memory".

Exception in sending message thru SOAP from java file to web service

Hi,
I am trying to invoke a web service from a java file.
But my code error out at particular statement where I am sending the message i.e. at
SOAPMessage reply = connection.call(message, destination);
The error message is
java.security.privilegedactionexception: javax.xml.soap.SOAPException: Message send failed: For Input string "".
I am using the wsdl link in destination variable-
String destination = "http://soad.xxxxxxxxxx.org:80/soa-infra/services/default/xxxxxx/xxxxxxx?WSDL";
Please help me with the solution.

Guys, any ideas because this is driving me a bit insane...
If you have any alternative implementations I'm open to them but I'd like to know why isn't this working really...
Thanks and regards

Loading *.txt files in web service

I have a running web service on Axis, and can communicate with it from a j2se client and a browser test client.
I'm attempting to load a txt file of data in the web service (stores a list of usernames). But the code can't locate the text file. Where are external resource placed if they're needed in a web service? I was assuming I could just place it next to my *.java files.
Thanks

I should add that I'm using Eclipse , and as such my web service seems to be self contained in my workspace for Eclipse. The structure is
EclipseWorkspace -> myProject -> projectNamespace -> *.java
I thought I could place my *.txt files inside the namespace directory with my Java files. I have also tried placing the *.txt file in the project directory, still no luck.

Modifying properties with a file for Web Service Stub used for Oracle Forms

I have created a stubbed-out web service in JDeveloper (10.1.3.4) and imported into Oracle Forms.
However, I would like to use a properties file to call the appropriate endpoint based on if the environment is dev, test, UAT or prod. I see that a properties file is referenced in the _Stub class. Here is a snippet of code from that class file:
public CriticalChangeWS_Soap11_Stub(HandlerChain handlerChain) {
super(handlerChain);
setProperty(ENDPOINTADDRESS_PROPERTY, "http://epw-01.gds.graebel.com:8087/CriticalChange.svc/Soap11");
setSoapVersion(SOAPVersion.SOAP_11);
setServiceName( new QName("http://tempuri.org/","CriticalChangeService"));
setPortName( new QName("http://tempuri.org/","CriticalChangeWS_Soap11"));
setupConfig("wsquery/proxy/runtime/CriticalChangeWS_Soap11_Stub.xml");
How can I use the XML file to set the ENDPOINT_ADDRESS_PROPERTY?
Thanks.

Hi Frank,
I got the following two lines of code just to check if WebServiceConnection was able to read the connections file alright.
            String urlString = wsc.getWsdlUrlStr();
            System.out.println("WSDL URL: "+urlString);
I am not using urlString for further processing.
The output is
WSDL URL: http://<host>/PSIGW/PeopleSoftServiceListeningConnector/MyService.1.wsdl
java.lang.NullPointerException
        at java.lang.Class.isAssignableFrom(Native Method)
        at oracle.j2ee.ws.common.jaxws.runtime.GenericJavaType.create(GenericJavaType.java:97)
        at oracle.j2ee.ws.common.jaxws.runtime.GenericJavaType.create(GenericJavaType.java:118)
The WSDL Url pointed to is the one that I configure in the connection while deploying the App.
Ran a test and WSDL Url is accessible by the app.

Out of memory when coverting large files using Web service call

I'm running into an out of memory error on the LiveCycle server when converting a 50 meg Word document with a Web service call. I've already tried increasing the heap size, but I'm at the limit for the 32 bit JVM on windows. I could upgrade to a 64 bit JVM, but it would be a pain and I'm trying to avoid it. I've tried converted the 50 meg document using the LiveCycle admin and it works fine, the issue only occurs when using a web service call. I have a test client and the memory spikes when it's generating the web service call taking over a gig of memory. I assume it takes a similar amount of memory on the receiving end which is why LiveCycle is running out of memory. Does any one have any insight on why passing over a 50 meg file requires so much memory? Is there anyway around this?
-Kelly

Hi,
You are correct that a complete 64bit environment would solve this. The problem is that you will get the out of memory error when the file is written to memory on the server. You can solve this by creating an interface which stores large files on the server harddisk instead, which allows you to convert as large files as LC can handle without any memory issue.
