I am trying to get a Java Servlet logged into an extranet system, pull down
search results, and logout. However, I keep getting weird results.
First I get a MUE when I first login, what I found out is the server takes
the login form and send the results to another URL as parameters. Now, the
forwarding URL string gets flagged as an MU exception. However, just to get
past it, I did a real no-no and put code in the exception to then forward to
the real URL with the parameters. OK, it looks as if I get in, then I set up
the search parameters, headers and the cookies and when I execute the
sendGetRequest, 8 out of 10 times nothing happens, but 2 times out of 10, I
get a socket error. I have tried to catch anything I can think of but
nothing works. Any ideas?
Here's the code:
try {
resServlet.tools.writeLog("Entering site");
URL url1 = new URL("http", "www.extranetsite.com",
"/client_login.asp");
//login
HttpMessage lmsg = new HttpMessage(url1);
Properties lprops = new Properties();
resServlet.tools.writeLog("Starting Login");
Cookie[] lcookies = request.getCookies();
if (lcookies!= null) {
for (int i=0; i < lcookies.length; i++) {
cname = lcookies<i>.getName();
cvalue = lcookies<i>.getValue();
resServlet.tools.writeLog("Cookies: " + cname +" ," +
cvalue);
if (cname.equals("JSESSIONID")) {jsession=cvalue;
resServlet.tools.writeLog("JSESSIONID" + jsession);}
}
}
lprops.put("username","[EMAIL PROTECTED]");

Any ideas? Any thing for me to try?
