Weblogic startup servlet load

          Hi,
          I am encountering problems in running a Servlet on Weblogic
          server startup.
          The steps to be followed to execute a servlet on webLogic
          Server startup are as follows
          Register the following in the Weblogic properties
          file.
          1.register the servlet
          weblogic.httpd.register.MyServlet=\
          examples.servlets.myservletclass
          2.weblogic.system.startupClass.StartMyServlet=\
          weblogic.servlet.utils.ServletStartup
          3.weblogic.system.startupArgs.StartMyServlet=\
          servlet=MyServlet
          where MyServlet is the synonym used for registering the
          servlet in the file and myservletclass is the Actual
          name of the servlet.
          I have followed the steps accordingly but the server
          is failing to execute my servlet on startup.
          Any suggestions,solutions for the above problem
          will be most welcome.
          Thanx
          Tapan.

HOw did you specified the load-on-startup? and what error you get
          upon startup/deployment time?

load-on-startup 1 /load-on-startup not working in Weblogic 9.1

Hi
          I have the following xml tag in web.xml file
          <load-on-startup>1</load-on-startup> for some servlets, i have given then sequence 1 to 5, but for some reason 5 is loading first and the whole application crashes because of this.
          do i have to mention anything in weblogic.xml?
          Any ideas how do i fix this

You're right, your situation is very similar to the situation the other poster describes. However, the main similarity is that neither of you have given us any information about what is going wrong. We can't read minds or read what's on your screen. We need to see specific error messages, stack traces, and specific code that shows what you are trying to do.
          However, it's likely that you're running into problems with the issues with "tag reuse" and "tag pooling". You should first read the JSP specification in the areas that talk about this issue, although this will probably leave you with more questions than you started with.
          I'm guessing that your "<gui:button>" element doesn't have any attributes. It's possible that WebLogic is reusing a single "<gui:button>" tag instance for each occurrence in your page. You may have to figure out how to turn off tag pooling in the JSP compiler, but I'm not sure how to do that.
          It's possible that Websphere doesn't give you an issue with this because perhaps they didn't bother with the tag pooling optimization (it is a good thing to have it available).

How long load-on-startup servlet stays in weblogic6.1 sp2

does anybody know how long a load-on-startup servlet exists (before
          gets destroyed) in weblogic6.1 sp2. What i want is in load-on-startup
          servlet, I want to schedule a java.util.Timer and when application
          gets undeployed, i want to cancel that timer. if load-on-startup
          servlet exists for the whole application life span then i could do
          timer.cancel() on the destroy method of load-on-startup servlet.
          any suggestion?
          thanks in adv,
          soumik


You can simply use ServletContextListener instead - that way you do not
          have to worry if (or when) WebLogic decides to destroy the servlet.

Weblogic 7.0 startup servlet problem

I have added a new startup servlet to my existing web application.
          While deploying the same, weblogic is throwing the following
          exception.
          I'm very sure that class (com/lbx/util/LbxProperties) is part of
          webapp war file I created. Can somebody please throw some light about
          this.
          I'm trying to do the .ear file deployment.
          Thank you very much

          Hi Santhosh,
          Yeah , if its part of the system class path, it should find it. How are u referencing
          the file? Try wrapping the code that gets the Resource and see what exception
          you get.

Servlet load on server startup ?

With WebLogic 4.5.1 can you specify a servlet to load when the server
          starts ?.
          Thanks
          Peter.


          Hi Kumar
          I have installed BEA Weblogic through Webgain Studio. I remember to have chosen to install Weblogic with the Service Packs.
          How do I know if I have installed the correct service packs.
          I still have this problem that 'main not found' in a startup servlet.
          Thanks

Load on startup servlet and references

          Weblogic 6.1 SP2
          No jars specified in the classpath. A Singleton is located in a utility.jar file
          inside a .ear file.
          If I create a Singleton from a load on startup servlet, how long will the singleton
          be around? I know that if I undeploy the application, the singleton will be destroyed
          since the classloader is unloaded. However, if I never undeploy my application,
          will the Singleton always be around? Does Weblogic keep a reference alive to
          this Singleton forever?
          Please provide some more details on this!
          Thanks.
          Dan

          A class object is not an instance object. If the class object has been loaded by the
          classloader, it will not be unloaded or garbage collected, regardless of whether or not
          it has static methods. If an instance of a class is instatiated on the heap, and a
          reference to that object is placed in a static member of its associated class object,
          also referred to as a class member, then the instance will not be garbage collected.

"load-on-startup" servlet configuration

Dear All,
I am trying to load a servlet "SettingServlet" at the startup of the application, the configuration I am using inside the web.xml file is as following:
<web-app>
     <servlet>
     <servlet-name>SettingsServlet</servlet-name>
     <servlet-class>com.myPack.SettingsServlet</servlet-class>
     <init-param>
     <param-name>fichierConfig</param-name>
     <param-value>D:/tomcat41/webapps/init.conf</param-value>
     </init-param>
     <load-on-startup>5</load-on-startup>
     </servlet>
</web-app>
It seems that the "SettingsServlet" servlet is not started at the startup.Even it's started in the tomcat window I am getting something like
(SEVERE: Parse error at line......column...:Element type ....not declared ..)
and that for the servlet-name, parma-name,servlet-class, init-param...etc
Do I missed something in the configuration?, please tcheck the few lines above. because Simply I got stuck ! ,,,,,Please help me to fix it, I am waiting for you reply guys.
Thanks and Regards,
kifwet

Take a look at the header of your web.xml file, the part about:<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd"> And go check the dtd for your version.
Some versions are very picky about the order of parameters.
Hope this helps.

When i look into the directories weblogic created after deployment, there is a
cls2372.jar at 1 level above the web-inf folder and it has all the servlets in
the correct package structure i.e. com/abc/servlets/startup
Any idea on why this is happening or what i am doing wrong?

also posting to servlet newsgroup.

Weblogic startup class (urgent)

Hi All,
I need a java program (weblogic startup class) which should fetch data from the database and instantiate another one class (it will be the data holder) and store that object into a webapplication context. Anyone tried this? Since its urgent any help will be appreciated.
Thanks in advance
Cheers,
Pandiaraj

Do this in the init() method of a servlet and start
the servlet when you start your weblogic server
second that. just give a value of 1 for <load-on-startup> in web.xml

Startup servlet problem in weblogic81

Hi
I created one web application in weblogic81 and it contains one servlet and act as startup servlet.When i m trying to get jndi context to connect to DataSource in init method, i m getting the following exception
javax.naming.CommunicationException [Root exception is java.net.ConnectException: t3://16.138.181.88:7501: Dest
ination unreachable; nested exception is:
        java.net.ConnectException: Connection refused; No available router to de
stination]
init method
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL,"t3://16.138.181.88:7501" );
jndiContext = new InitialContext(env);
web.xml
<servlet>
<servlet-name>MyServlet</servlet-name>
          <servlet-class>com.MyServlet</servlet-class>
          <load-on-startup>0</load-on-startup>
</servlet>
Please help me out.

Chandra

To use the /servlet/ notaton you will need to enable the invoker servlet. To do this open the conf/web.xml and search on "invoker". Follow the directions.
An alternative would be to map the servlet to a url and use that url to call the servlet
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/TestServlet</url-pattern>
</servlet-mapping>
now you should be able to access the servlet with /Fortune/TestServlet

Problem setting up startup servlets in iWS 4.x

I have configured iPlanet Web Server(iWS) 4.1 SP9 to use a startup servlet. However, the error log does not show that the servlet has been initialized. Instead, it shows only the following entries:
Loading Simple Session Manager by default. Specify MMapSessionManager in servlets.properties to load persistent session manager
I found in the Knowledgebase that we need to copy the the configuration entry that was created in context.properties file into the servlets.properties file
My question that ...do we need to copy all the contents of the context.properties file or some portion of that file to servlets.properties .
Please suggest asap, I cant take a risk as this is a live server.
Thanks.

Hi,
You need not to copy entry file. In your servlets.properties file at the end of the file you can see the parameters settings of servlet which you have been configured as a servlet.
For example the below setting are for "HelloWorldServlet" servlet configuration. You need to copy that line only.
servlet.HelloWorldServlet.classpath=/export/home/41sp9/docs/servlet
servlet.HelloWorldServlet.code=HelloWorldServlet.class
Note: Make sure that before changing(copying)any changes in file take backup of the old file(present).
Regards,
Dakshin.

What will happen if i mention like load-on-startup -1 /load-on-startup ?

Hi All,
In my web.xml what will happen if i mention like <load-on-startup>
-1</load-on-startup> ?

It's not WebLogic-specific, the load-on-startup web.xml element is a standard common component to all application servers.
As for what it does, then yes, the BEA link explains it well enough. So that explanation applies to WAS too.

What does this mean ---- load-on-startup 1 /load-on-startup

Hi All,
Anybody please tell me what does this mean:
<load-on-startup>1</load-on-startup>
Thanks in advance
amitindia

From the dtd :
The load-on-startup element indicates that this servlet should be
loaded (instantiated and have its init() called) on the startup
of the web application. The optional contents of
these element must be an integer indicating the order in which
the servlet should be loaded. If the value is a negative integer,
or the element is not present, the container is free to load the
servlet whenever it chooses. If the value is a positive integer
or 0, the container must load and initialize the servlet as the
application is deployed. The container must guarantee that
servlets marked with lower integers are loaded before servlets
marked with higher integers. The container may choose the order
of loading of servlets with the same load-on-start-up value.

Servlet load balancing

I am testing load balancing of servlet on Weblogic 6.0 with Netscape
          Enterprise Server 3.6. I can hit both weblogic servers if I try to hit
          them heavily. However no matter what I do I can not get the round robin
          work.
          Has any one got load balancing work for servlets with 3rd party web
          server? As I understand weblogic only supports round robin for servlets
          load balancing because of DNS rotatioin, am I right?
          Thanks,
          Yong


          Yes. I even see this behavior from clients on different hosts.
