Problem in converting Lejos Class file into WSDL

[rahat khan]

Hi all,
I am Working on Bpel Workflows and for that i need Web services (WSDL) files and before that i've been generating those WSDL files from java class files and when i switched to lejos Api I wanted to alse generate wsdl files for lejos generated java class files but while i am writing command on console for the WSDL files generation of lejos Based JAVA Class files its giving me "NoClassDefFound Error" that is its not being converted into WSDLs kindly help me out if anyone can

There really is no difference between a leJOS class file and any other Java class file, so I suspect that the problem here may be something like the class path being used. Which leJOS classes are you trying to convert?

Thank Alot for your reply Actually i was making a mistake that i didn't write the package correctly when i went through the whole process again , i found it

And can you please help me out in finding that LEGO NXT robo will either work with web services called in Bpel Workflow SOA (Service oriented architecture)

Note: These web services which are created are of Java Code (Lejos)

Sorry no idea, have never used Bpel...

It is highly likely, that you cannot run webservices on the NXT itself, if that is what you're asking.
It should work if you run webservices on the PC, and remote control the NXT. LeJOS provides an API to connect and remote control the NXT.

Thanks a lot for your replies cheers for you guys

Yeah we cant run web services on NXT ... But you are talking about that it will work as if i do run web services in PC and then connect to the NXT ..
Now there is another question that to invoke web services me must have a client .. and currently that client is my BPEL Workflow which invokes those web services .. Will it work with BPEL ???
Or i should create a JAVA based Client ??
another question its too foolish but can you guide me regarding that API which you've talked abt connecting NXT Remotely ?? Thanking you in Anticipation

I have no clue about WSDL. However, when using leJOS to communicate with an NXT, leJOS is just another library, like any other library. You may have to write your own classes that implement the webservices. But those classes can rely on the leJOS library when it comes to communication with the NXT.

Thank You very much for the replies , my queries are almost solved thanks again Cheers for you guyz

Hi,

we did that; let's say, we implemented our own workflow engine (as BPEL engines are not powerful enough - it is another story) that invokes Web Services operations. Such WS operations wrapp LeJOS API (we are not wrapping all LeJOS API operations but those that interest us). Web services are deployed on Axis2 (or Tomcat+Axis2 container). It works on a 32 bit Windows machine (i.e. Win XP). We have also implemented those infrastructure on virtual machines (virtual windows guest hosts on linux servers). I am now working on porting such infrastructure to OSX Lion platform. It currently fails with USB communication (but painfully more or less works with Bluetooth).

Cheers.
