Disable servlet reload

          I need to disable servlet reload(WLS 7 SP4) for performance reason. I set the
          servlet-reload-check-secs to -1 in the container-descriptor of the web.xml of
          my war file. However when I deploy my war file, from the admin console the "Reload
          Period" is set to 1. Is there a way to make the deployment set the default "Reload
          Period" to -1 during deployment? I hate to deploy, change "Reload Period" from
          console, shutdown server, them restart server. Thanks.

 You can use the following in your web.xml
 <context-param>
 <param-name>weblogic.servlet.reloadCheckSecs</param-name>
 <param-value>-1</param-value>
 </context-param>

How to make servlets reloadable in iplanet web server in solaris??

hi all,
does anyone know how to make servlets reloadable in iplanet ??? Thanks for help

Hi there,
I think your question is about "Dynamic Class Reloading", also named as Hot deployment. and the following lines may be helpful.
iAS 6.0 SP3 and later version supports new hot deployment features through dynamic class
reloading of EJBs.By default, dynamic servlet, EJB and registered JSP reloading is disabled in iPlanet Application Server.
To enable dynamic reloading of servlets, EJBs and registered JSPs, perform the following steps:
1.Start iPlanet Registry Editor, kregedit, and modify the Disable value under the Versioning key:
SOFTWARE/iPlanet/Application Server/6.0/CCS0/SYSTEM_JAVA/Versioning
2.Set the Disable value to 0 (By default, the Disable value is set to 1)
3.Restart iPlanet Application Server to enable the change
To hot deploy your application, simply compile and replace the file in the appropriate directory or, use iasdeploy to redeploy
applications.
I recommand you to check out the iAS's release notes (http://docs.iplanet.com/docs/manuals/ias/60/sp3/rn_sp3.html#20766) for more infomation.
Good luck

Disabling dynamic reloading

Hi, i'm using iWS 6.0 SP2 on solaris 8 and i don't know how to disable dynamic reloading of classes. I have tried to set the reload-interval parameter to a negative number, to set the class-loader classpath parameter to "", but it still reloads the classes.
The only thing i can think of is setting the reload-interval to a huge number, but there must be another way.
Juan

It's always Microsoft who gets blaimed ;-)
          First, I am almost certain that any OS will not let you copy a file if there
          is an opened file descriptor of the file owned by some other process.
          Second, luckily the class loader code that handles this is pure Java, so it
          takes advantage of garbage collection here: if there is a live reference to
          an object, it's not going to be freed under you.
          Hope this helps.

Disable servlet autodeploy in nostage mode

We're running Weblogic 8.1 SP5 on Solaris. The documentation for staging mode nostage includes the following:
 
"With nostage deployments of exploded archive directories, WebLogic Server automatically detects changes to a deployment's JSPs or Servlets and refreshes the deployment. (This behavior can be disabled if necessary.)"
 
Questions: 
1) How does one disable the behavior (Note: We tested and the behavior exists by default in both Production and Development modes)?
 
2) Is there any way to disable auto-refresh for Servlets but not JSP?

I believe you should be able to set servlet-reload-check-seconds to -1 and set the JSP reload parameter to something else.

How do I disable the reload on the back button of Firefox and have it display the cached/prior page version?

Every time I click the "back" button, Firefox reloads the previous page I was on. How do I disable the reload and have Firefox display the cached/prior page version? The whole point of going "back" is to see what we were just looking at.. I don't want a refreshed version of it. Any help would be greatly appreciated! I am running version 3.6.12.

No problem. It's not a request that's been seen much if at all to be honest. I rely on them myself.
You can always feel free to provide feedback to Apple though.

Servlet reloading doesn't work

Running WL 5.1 SP6 and can't get servlet reloading to work. Have the
 necessary lines in weblogic.properties:
 weblogic.httpd.servlet.classpath=<my classpath>
 weblogic.httpd.servlet.reloadCheckSecs=1
 The servlets are in a web app so I have the web app's WEB-INF/classes, where
 the servlets reside, in weblogic.httpd.servlet.classpath.
 Possibly this is a problem only with web apps? Anyone else run into this?
 Thanks.


From my understanding, putting the servlet classes in the WEB-INF/classes
 directory eliminates the need to put them into any classpath (servlet, weblogic,
 or otherwise). Put them back into the WEB-INF /classes directory and make sure
 that this directory is not in the weblogic or servlet classpath.
 Hope this helps,
 Robert

Servlet reloading not working with WLS 5.1 sp8

 I downloaded and installed WLS 5.1's sp8 to fix the "java.net.SocketException: Connection aborted by peer: socket write error"
 problem. Although that problem is fixed, I have found that, however, the servlet (automatic) reloading does not
 work anymore. If I remove the sp8 from my Java system classpath and WL classpath (i.e. not using sp8), then
 the servler reloading works fine.
 Does anybody experience similar problem or have I forgot to do something?
 WLS properties/env vars setting:
 - weblogic.httpd.servlet.reloadCheckSecs=0
 - WEBLOGIC_CLASSPATH=%WEBLOGIC_HOME%\lib\weblogic510sp8.jar;...
 - JAVA_CLASSPATH=%WEBLOGIC_HOME%\lib\weblogic510sp8boot.jar;...
 Thanks in advance for any help.


 I've experienced the same problem with both sp6 and sp8. In both cases I performed several test, including
 - varied the value of weblogic.httpd.servlet.reloadCheckSecs
 - changes to the package depth the servlet belonged to
 - changes to the string length of the package names the servlet belonged to
 At best, the servlet would reload sometimes. I've moved back to sp5 and the problem has subsided.
 Note: I did not try registering the servlet to see how that would effect the dynamic reloading.
 Hope this helps

How do I disable automatic reload of web pages when forced quit is uaed?

I ran across a web site that was part of a scam. It pretended to be one of the security programs on my computer and reported that my Computer had malware (it was the malware). The only way out and not activate the scam program was to use the Windows Task Manager to kill Firefox.
When you do this the next time Firefox is started it tries to reload the last pages visited including the bad web site. How do I disable this feature? Or force Firefox to ask me which pages to load every time.
Automatic should not be allowed because of these scams. Fortunately I had a work around, I pulled the network cable when I restarted Firefox causing a different failure that could be cleared.

Set the pref [http://kb.mozillazine.org/browser.sessionstore.max_resumed_crashes browser.sessionstore.max_resumed_crashes] to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.
That will allow you to deselect the tab(s) that you do not want to reopen, but will allow to reopen the other tabs.
See:
* http://kb.mozillazine.org/Session_Restore#Restoring_a_session_after_a_crash

Weblogic servlet reload won't work

Please help! I am using WLS 5.1 sp6 (NT) and trying to use the auto reload setting for the servlets but weblogic won't refresh the change dynamically. I have set the following entries in the weblogic.properties file:
 weblogic.httpd.servlet.classpath=D:/weblogic/myserver/servletclasses
 weblogic.httpd.servlet.reloadCheckSecs=1
 Thanks in advance.
 Peter


 It would be really nice if WL would report that with an error/warning message.

Servlet Reloading Problem!

JSP + Bean is OK!
But, Servlet + Bean occur a reloading problem.(Reloading does not happen)
For example,
1) TestClass.java (Bean)
public class TestClass {
private String txt;
public TestClass() {
txt = "Test!!"; ---(1)
public String getTxt() {
return txt;
2) Test.java (Servlet)
public class Test extends HttpServlet {
public void service(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
TestClass testClass = new TestClass();
PrintWriter out = res.getWriter();
out.println(testClass.getTxt());
In above examples, though I change txt String(number (1)) Bean reloading does not occur. So old txt String shows.
In Tomcat, such problem does not happen.
Is this a problem of OC4J?
Thanks.
null

Well, only servlets are supposed to be reloaded, not their dependent classes.
If you are using Tomcat 4.x, then there might be an explanation. It seems that Tomcat 4.x will simply reload the entire web app context if it detects that a servlet (not a JSP!) has changed. Just define a servlet context listener to see that.
