Invoke a call to Muse in Axis
Hello,
I want to add identification function and maintain sessions in the Muse
service. Now I have deployed one Muse service and one Axis service. I invoke
a call to Muse service from Axis implemention file.(e.g. Once the Axis
service receives a GetResourceProperty soap request, it will do the
invocation to Muse service to get the required resource property.)
The following is the code of method getResourceProperty in the Axis
generated impl file. But it dose not work, it returns a NullPointer
Exception. I don't know where the problem is. Can anyone help?
Thanks in advance.
I attach as well the WSDL file, the GetResourceProperty.soap and
GetResourceProperty.xml.

Invoke a call to Muse in Axis
Posted by ZHAO <zh...@gmail.com>.
Hello,
I want to add identification function and maintain sessions in the Muse
service. Now I have deployed one Muse service and one Axis service. I invoke
a call to Muse service from Axis implemention file.(e.g. Once the Axis
service receives a GetResourceProperty soap request, it will do the
invocation to Muse service to get the required resource property.)
The following is the code of method getResourceProperty in the Axis
generated impl file. But it dose not work, it returns a NullPointer
Exception. I don't know where the problem is. Can anyone help?
Thanks in advance.
I attach as well the WSDL file, the GetResourceProperty.soap and
GetResourceProperty.xml.

Invoke a call to Muse in Axis
Posted by ZHAO <zh...@gmail.com>.
Hello,
I want to add identification function and maintain sessions in the Muse
service. Now I have deployed one Muse service and one Axis service. I invoke
a call to Muse service from Axis implemention file.(e.g. Once the Axis
service receives a GetResourceProperty soap request, it will do the
invocation to Muse service to get the required resource property.)
The following is the code of method getResourceProperty in the Axis
generated impl file. But it dose not work, it returns a NullPointer
Exception. I don't know where the problem is. Can anyone help?
Thanks in advance.
I attach as well the WSDL file, the GetResourceProperty.soap and
GetResourceProperty.xml.
