Hello all, Is there a way a method in a soap service can return an object (java.util.List) as attachment with out using soap specific classes. I was looking at the mime example in soap samples and it was using ByteArrayDatasource which is soap specific class. The example I saw looked like this: DataSource ds = new ByteArrayDataSource(new File(fname[i]), null);
I think my question probably is "Is there any way to build a DataHandler object w/o using apache soap tool on the server side?" I am trying send the java.util.List as an attachment. the list has strings in it. The reason I want to send it as attachment is because the list has 1000s of strings and sending it as List will fillup the soap envelop and putting overhead of parsing the huge xml which in turn is filling up all my memory with the parsed document. If I send the same list as an attchment, I am assuming that I will not have this problem. The size of the list itself is not a problem I think. Its the size of the soap envelop thats killing the app. Am I right? The reason I do not want to use soap specific classes is because our soap services are plain java classes and designed such a way that we can swith to any soap tool in the future. Thanks.
