the code i am using is

call.invoke(new Object[] { request });





This is the code to download that

// create a call object

org.apache.axis.client.Call call = (Call) actuateAPI.createCall();



// set the parameters

prepareDownloadFileCall(call);



// set download message

com.actuate.schemas.DownloadFile request =

new com.actuate.schemas.DownloadFile();

request.setDecomposeCompoundDocument(decomposeCompoundDocument);

request.setDownloadEmbedded(downloadEmbedded);

request.setFileName(filename);



// invoke the call object

Object resp = call.invoke(new Object[] { request });



And it continues ?the error is in the last line specified here
