Hi,
How can JAVA application can interact with wM (how can they call our service directly? apart from calling our webServices).
Do wM application team needs to send any of their jar files to Java application team?
Thanks in advance,
Sam
Using http you can call a wm service directly.
Use http://servername:port/invoke/Service_FullyQualifiedName
You can also exchange data using FTP.

You can call the service directly using code like this from a java program:
Context context = new Context();
IData input= IDataFactory.create();
IDataCursor idc = input.getCursor();
idc.insertAfter("myVariable", "Hello!");
idc.destroy();
context.connect("distantHost", "login", "password");
IData output = context.invoke("folderName", "serviceName", input);
//manage outputyou just have to send your application team the client.jar which contains the right classes (IData etc.)
And may I suggest some documents on how to use services and messaging instead of RPC based calls. 
Both of which are very easy to do from Java.

Am seeing “ws-isclient.jar” file not “client.jar” file (do we have any other client jar file to be included?)
Any correction please.

Hi All,
It worked now when tried as below from command prompt
C:>java -classpath .;C:\webMethods7\common\lib\ext\mail.jar;C:\webMethods7\common\lib\wm-isclient.jar temp1
But don’t know the reason why it didn’t work earlier(because I have set classpath the same as typed in command prompt, CLASSPATH=.;C:\jdk1.5.0_19\jre;C:\webMethods7\common\lib;C:\webMethods7\common\lib\ext;
)
Thank you all.
Sam.
As per the other thread on this topic, IMO, this is not the way to go. Using the IS Java API ties the Java app to IS and isn’t any simpler than using XML over HTTP (you’ll find many more developers know how to do that than use the IS Java API).
The first attempt didn’t work because the jar file wasn’t on the classpath. When class files are in a jar/zip, that jar/zip must be explicitly on the classpath. Having the directory in which it is located is not sufficient.
Hi Rob,
Thanks for your information.
Regards,
Sam.
