Fw: Applet Servlet communication in Tomcat 7
Hi Folks,
I have applet code for connecting servlet, It works fine in Tomcat 6, when i
upgraded the tomcat version to 7. it is not working.
Using this code for connecting Servlet. this will download a file to client
machine but it is not going to servlet itself.
URL servletURL = new URL(url);
URLConnection servletConnection = servletURL.openConnection( );
servletConnection.setDoOut put(true);
servletConnection.setUseCa ches(false );
InputStream in = servletConnection.getInput Stream();
StringBuffer response = new StringBuffer();
int chr;
while ((chr = in.read()) != -1) {
response.append((char) chr);
}
in.close();
Writer output = null;
File newfolder = new File(localPath);
boolean newflag = newfolder.isDirectory();
if (!newflag) {
newfolder.mkdirs();
}
File file = new File(localPath + fileName);
if(file.exists())
file.delete();
output = new BufferedWriter(new FileWriter(file));
output.write(response.toSt ring());
output.close();
the below one is applet code
<applet name="loadApps" code="com.utilapps.UtilApp lication.c lass"
codebase="../utilapps/" archive="../utilapps/utila pps.jar" width="300"
height="300" align="baseline">
<param name="fileName" value="<%=fileName%>">
</applet>
and the debugs got in console
basic: Applet made visible
basic: Starting applet
network: Connecting https://localhost/utilApp/ servlet/Ut ilAppsServ let?mode=0
& fileName= filea.ARA with proxy=DIRECT
network: Connecting https://localhost/utilApp/ servlet/Ut ilAppsServ let?mode=0
& fileName= fileb.ARA with cookie "user=help; ZP_CAL=%27........"
network: Server https://localhost/utilApp/ servlet/Ut ilAppsServ let?mode=0 &
fileName= filec.ARA requesting to set-cookie with "JSESSIONID=AC3E134CEAF903
20BA442DF8 81B8F5AD.t omcat7; Path=/utilApp; Secure; HttpOnly"
basic: Applet started
Eagerly waiting for your reply. Please let me know if i need to change any
settings in Tomcat 7
Thanks,
Ram Karthik.

Pretend I don't believe that the applet is broken in Tomcat 7.0. Please
prove that it is broken.
Producing log data from Tomcat which indicates an error would be a good
start.

Hi Warren,
Thanks for your response.
I didn't got any errors either in java console Or in tomcat 7 logs. actually the
code is working well in tomcat 6. the same code do not work with tomcat 7, also
want to know do we need to set any specific settings for applet servlet
communication in tomcat 7.
Thanks,
Ram Karthik.

You didn't specifically state what the actual error was and so without
giving more detailed information about what you expected to happen and
what happened instead I don't see what we can do.
