I am looking at the UploadTest servlet from Jason Hunter's Java Servlet
Programming. This works fine using a html form like this ...
<FORM ACTION="/wpe/servlet/UploadTest" ENCTYPE="multipart/form-data"
METHOD=post>
What is your name? <INPUT TYPE=TEXT NAME=submitter> <BR>
Which file do you want to upload? <INPUT TYPE=FILE NAME=file> <BR>
<INPUT TYPE=SUBMIT>
</FORM>
However, I would like to call this servlet from within a Java program.
I tried to use Oreilly's HttpMessage class to call the servlet...
urlStr = "http://localhost:8080/wpe/servlet/UploadTest";
URL url = new URL(urlStr);
HttpMessage msg = new HttpMessage(url);
Properties props = new Properties();
props.put("submitter", "wayne");
props.put("file", "c:\\kuz7.jpg");
InputStream in = msg.sendPostMessage(props);
At this point I get an exception regarding it not being
multipart/form-data.
I tried modifying HttpMessage (where the Netscape bug fix code is)
to get the content type right. Then I go a "missing boundary" error.
I then tried setting the content type in HttpMessage thus
con.setRequestProperty(
"Content-Type", "multipart/form-data;
boundary=---------------------------2799030872219");
At this point the java app just hangs there, ruminating on its purpose.
The multipart aspect of the called servlet seems to be the problem.
If I could just understand what information the form is sending, perhaps
I could emulate it better from within Java.
I feel I am loitering in hack city, drifting further and further away
from the simple truth I need to proceed. Can someone explain what needs
doing to get this app to work.
