Could there be a session tracking problem when an HTTP client that runs in a servlet tries to read an HTTP response from a remote webservice? I wrote a servlet that calls a remote webservice via an HTTP client. The HTTP client is posting the correct XML to the webservice but in the HTTP resonse I am getting an html response liek the one at the end of this message. Runtime Error body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px} b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px} H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red } H2 { font-family:"Verdana";font-weight:normal;font-size:14pt;color:maroon } pre {font-family:"Lucida Console";font-size: .9em} .marker {font-weight: bold; color: black;text-decoration: none;} .version {color: gray;} .error {margin-bottom: 10px;} .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; } <H1>Server Error in '/PBSITest' Application.<hr width=100% size=1 color=silver></H1> <h2> Runtime Error </h2> Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". <table width=100% bgcolor="#ffffcc"> <!-- Web.Config Configuration File --> <system.web> </system.web> Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. <table width=100% bgcolor="#ffffcc"> <!-- Web.Config Configuration File --> <system.web> </system.web> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4188105#...
