Server returned response code 500 for the url

I have an applet which connects to a servlet.I have just upgraded from Java 1.5_06 to Java 1.6_027.
I have a login.html which opens up when i hit the url http://localhost:80/test/testlogin.html.
The IIS 7 opens this page and then when I provide login credentials it should connect to the testServlet but I get
an IOException at the line
ObjectOutputStream out = new ObjectOutputStream(conn.getOutputStream());
saying 'Server returned code 500 for the url http://localhost:80/test/testServlet.class
I am using the following lines of code
conn = servletURL.openConnection();
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestProperty("Content-Type", "application/octet-stream");
ObjectOutputStream out = new ObjectOutputStream(conn.getOutputStream());
This code use to work fine with Java 1.5 but it doesnt work after the upgrade.
I am not sure if it is a Java problem or IIS or Weblogic.
Please help
Thanks,

Thanks,Well, HTTP 500 is Server Exception, look at the server logs and find out why it threw a 500.

IOEXCEPTION:sever returned response code 500:for url:-----

hello sir we are developing a project for a transportation company in java with tomcat server 4.1 and the backend used is the sql server 7.0.In this software we are getting a problem while entering a particular date such as 24/04/2003 for storing it in the database for further processing. While entering other dates for processing we are not getting any problem. The error what we are getting is
ioexception:http response code 500 for specified url.
sun.httpconnectionurl.this project is mainly based on the accouting years we are storing for example an accounting year may be in this form like 01/04/2003 to 31/03/2004. so please find a solution as early as possible for me.

Generally, if you're getting a 500 error on a JSP/Servlet, it's because an Exception is being thrown and not caught. If you are using a JSP, you can make a generic errorPage to handle all errors. For a quick fix for debugging purposes, though, just put all your code in a try {} block, and catch all Exceptions and print out the error message.

Segmentation Error : Server returned HTTP response code: 500 for URL

Hi,
when we do customer segmentation in Applet Java Builder, we create a target group using 2 or more criterion, then it prompts us an error "Communication Error" - Server returned HTTP response code: 500 for URL: http//xxxxxxxxxxx/bc/bsp/sap/CRM_MKTTG_SEGAP/communication.do
we're in CRM 7.0 SP 6.
What we have done
- activated the service CRM_MKTTG_SEGAP
- implement sap note 1481289, 1359890, 1161753
any info is really appreciated.
Thanks
JD

HI ,
Communication error occurs because of two active versions of segment builder jar files are appearing , deletion of older version resolves this issue .
Go to SE80 u2013 Select the BSP Application - CRM_MKTTG_SEGAP and check segmentbuilder.jar Segment Builder Applet under MIME folder and check the size and delete the older version .

Windows Azure Pack - Server returned HTTP response code: 500 error while accessing the public tenant API

Hi,
We are facing the following error while trying to access the given Windows Azure Pack Public tenant API to query the virtual machines list along with network adaper details -
java.io.IOException: Server returned HTTP response code: 500 for URL: https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines?$expand=VirtualNetworkAdapters&$top=10000&$skip=0
The response is proper when we access the following URL -
https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines
Only on adding the $expand=VirtualNetworkAdapters, url parameter we are getting the above error.
Where can we check for the error logs on the Azure Pack server ? We checked for the logs using Windows Event Viewer but did not find any for the public tenant API.
What should be the cause for such an error and how can we fix this to get the proper data?
Thanks in advance.

Yes, we tried this, $top=10&$skip=0 works for the following url
https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines?$top=10&$skip=0
It is only when we add $expand=VirtualNetworkAdapters,
the server returns the mentioned error response -
URL for which the server returns the 500 error -
https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines?$expand=VirtualNetworkAdapters&$top=10&$skip=0
Can
you point to the error logs for Windows Azure Pack and SPF ?

Java.io.IOException: Server returned HTTP response code: 500

Hi,
I am connecting to a servlet from an applet to send and receive data using the following code.
try
URL servletURL = new URL("http://www.progressivecoding.com/servlet/gatesqlang");
               URLConnection servletConnection = null;
               URLConnection servletConnection = servletURL.openConnection();
               servletConnection.setDoOutput(true);
               servletConnection.setUseCaches(false);
               PrintStream out = new PrintStream(servletConnection.getOutputStream());
               out.println("hhd8836gh828dhhskjdhn38847gosf747");
               out.close();
               InputStream in = servletConnection.getInputStream();
               StringBuffer response = new StringBuffer();
               int chr;
               while ((chr=in.read())!=-1)
                    response.append((char) chr);
               in.close();
               return response.toString();
          catch (IOException e)
          e.printStackTrace();
          tfTxtFile.setText(e.toString());
          return "An error occurred: " + e.toString();
Everything was working well and fine. All of a sudden without any change of code. It began to return this error to applet
An error occurred: java.io.IOException: Server returned HTTP response code: 500 for URL: http://www.progressivecoding.com/servlet/gatesqlang
But I am able to access the same URL from a browser.
Someone please tell me what could be the problem

hi, that error got solved, the SessID i was receiving in that code had some leading or trailing white spaces. so SessID = SessID.trim() did the job.
But i have a question. This program workd fine when i compile and run from my local system. But when i port this on to the oracle server (JAVA_TOP) and access this from a JSP, then the program performs very un-reliably.
The first data transfer works fine, i get the SessID, when i pass that SessID along with the DTSSessionID to the server, the server says that i doesn't recognise my SessID, and throws a client.Authentication Error.
So there goes the parsing out of the window for the data in the second iteration.

http response 505: http://libraries.ucsd.edu/about/tools/http-response-codes.html
This would indicate nothing is wrong with your applet but with your http server (not supporting http 1.1??)
A full trace might help:
To turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
if you cannot start the java console check here:
C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
add or change the following line:
javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
When you catch the exception you should print the stacktrace: (e.printStackTrace()).

Java.io.IOException: Server returned HTTP response code: 405 for URL

I'm trying write to a file using a combination of CGI and Java. I am following this website:
http://www.webdeveloper.com/java/java_jj_read_write.html
However, when I try to write out to the file, I keep getting the error in the title: HTTP response code: 405 for URL: .....
I was wondering if anyone knew what this mean? I searched the forum and found a post from 2 years ago that was exactly the same problem I was having, only thing is that there were no responses to it. Hopefully I'll have a bit more luck.

.and suddenly java.io.IOException: Server returned HTTP response code: 500

I have this code for a long time and it always works:
     URL url = new URL("http://www.infoamistades.net/load.do");
          URLConnection urlConnection = null;
          urlConnection = url.openConnection();
          urlConnection.setRequestProperty("Content-Type","text/html; charset=utf-8");
urlConnection.setRequestProperty("Accept-Charset","utf-8");
BufferedReader bin = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(),"utf-8"));
but....suddenly I always have the java.io.IOException: Server returned HTTP response code: 500 (?!?!?)
using this URL works properly
URL url = new URL("http://www.infoamistades.net/");
but now it doesn't works with URL url = new URL("http://www.infoamistades.net/load.do");
and putting thia addrees to the browser it works, of course..
no changes at the server, not firewalls.. (?!?!)
thanks,

Hi,
Actually I am also having exactly same problem that you mentioned, I am new to the world of servlets. I could not get what you mean by "put variable in the request" Please tell me exactly what to do to solve this problem.
Someone please help.........

Error:unknown error has occured;server returned http response code :500

Hi,
   I deployed one custom action block on 12.0 server.
   It creates a pdf doc and saves it under c:\sample on MII server.
   But when I run the action block in a trax, an error was logged: unknown error has occurred; server returned http response code :500 <server URL>
Need immediate help on this.
Thanks

Does the failure occur within the action, and if so can you identify where? It is always a good idea to put some logging at the debug level in your actions to help identify exactly where a failure is occuring.

Server returned response code 500 for the url
