Re: help with byte[]

Thu, 09 Mar 2006 01:06:10 -0800
i've written a class with 2 methods in it compress and uncompress and i've used the examples from java almanac 


http://javaalmanac.com/egs/java.util.zip/CompArray.html

and

http://javaalmanac.com/egs/java.util.zip/DecompArray.html


I've then done java2wsdl to create the wsdl file


Now i'm trying to cal lthe 2 methods using the web service

To call the compress method i'm just using this

String uncompressed = "some string in here to compress";

Service service = new Service();

Call call = (Call) service.createCall();

call.setTargetEndpointAddress(endpoint);

call.setOperationName("compress");

byte[] a = ((String)call.invoke(new Object[] {uncompressed})).getBytes();



Then i'm using 'a' to pass to the uncompress method like this

Service service1 = new Service();

Call call1 = (Call) service1.createCall();

call1.setTargetEndpointAddress(endpoint);

call1.setOperationName("uncompress");

String st = (String) call1.invoke(new Object[] {a});


But the 2nd call just hangs




<element name="compress">
   <complexType>
    <sequence>
     <element name="string" type="xsd:string"/>
    </sequence>
   </complexType>
  </element>
  <element name="compressResponse">
   <complexType>
    <sequence>
     <element name="compressReturn" type="xsd:base64Binary"/>
    </sequence>
   </complexType>
  </element>
  <element name="uncompress">
   <complexType>
    <sequence>
     <element name="bytes" type="xsd:base64Binary"/>
    </sequence>
   </complexType>
  </element>
  <element name="uncompressResponse">
   <complexType>
    <sequence>
     <element name="uncompressReturn" type="xsd:string"/>
    </sequence>
   </complexType>
  </element>

thanks for any help

I'm having a hard time following what you're trying to do. You could try:

1) Showing the entire wsdl.

2) List the steps of execution, ie, compressing / uncompressing, order of 
web

services calls etc.

Are you using the code from the java almanac I posted a few days ago?


Lastly, if the call is hanging, try putting the soap monitor or tcpmon on 
the

client / server to see where it hangs. Also try turning on logging on the
client and server side.

HTH,
