Order of startup servlets in WLS 5.1

          Is there any way to set the order in which servlets are started up using ServletStartup.
          I have something similar to this in my weblogic.properties file -
          weblogic.system.startupClass.StartServletA=weblogic.servlet.utils.ServletStartup
          weblogic.system.startupArgs.StartServletA=servlet=ServletA weblogic.system.startupClass.StartServletB=weblogic.servlet.utils.ServletStartup
          weblogic.system.startupArgs.StartServletB=servlet=ServletB
          I'd like ServletA to load first and then ServletB, but ServletB always seems to
          load first.
          Any ideas?
          Thanks...
          ps - using WLS 5.1, SP6

If, for some reason, you do not deploy your application as a webapp,
          you can use ServletStartup:

Servlets as Startup classes in WLS 5.1

Hi,
I would like to know if:
1) a servlet can be used as a startup class in WLS 5.1. If so,
are there any restriction on what can be done inside this servlet?
Or
2) can we load a servlet from a startup class? if so? how?
any ideas?
regards,
Modou.

Not sure if this is what you are looking for, but you can mark a servlet to
be pre-loaded when the servlet runner starts.

"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.

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.

When i look into the directories weblogic created after deployment, there is a

Any idea on why this is happening or what i am doing wrong?

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.

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.

          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.

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

          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.

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
          Santhosh.

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

GetInitParameter in startup servlet throwing NullPointerException

          I understand that if your Init Parameter contains nothing, getInitParameter will
          return null. Well, I'm checking for that, and I'm getting the NullPointerException
          while I'm trying to check for it?!?! Here's my code:
          excerpt from web.xml:
          <servlet>
          <servlet-name>startupServlet</servlet-name>
          <servlet-class>vw.action.startupServlet</servlet-class>
          <load-on-startup>1</load-on-startup>
          <init-param>
                    <param-name>applicationPath</param-name>
                    <param-value>hint_production</param-value>
                    <description>applicationPath</description>
          </init-param>
          </servlet>
          yes, I have a servlet mapping element
          code:
          public class startupServlet extends GenericServlet
          public void init( ServletConfig config ) throws ServletException {
               so("\n\t startupservlet 1 \n\t");
               try {
          // null is being thrown here, neither line below is output
               if ( getInitParameter( "applicationPath" ) == null )
               so(" null applicationPath initParameter ");
               else
               so(" applicationPath initParameter is NOT Null ");
          } catch ( NullPointerException npe ) {
               so( "\n\t setting blank path \n\t" );
               Constants.setPath( "" );
          public void service( ServletRequest req, ServletResponse res ) throws ServletException,
          java.io.IOException {
               public static void so( String output ) {
          System.out.println( output );


          I forgot to mention that I'm using WLS 6.1 (SP2)
          ps how 'bout that domain name? Marketing genius...

Problem in servlet engine (WLS 7.0) with the chunked transfer

Hi,
          While using jakarta-slide on weblogic 7.0, I encountered the following
          problem while uploading files using WebDAV servlet deployed on WLS:
          "**** This file has a corrupted %%EOF marker, or garbage after the
          %%EOF."
          Is this is a problem with the way that WLS servlet engine is handling
          chunked transfers ?
          According to the change request 084847, "For chunked
          transfer, WebLogic Server was including a hexadecimal number which
          other
          servlet engines used to ignore. This has been fixed WLS 6.1 sp 4."
          Is this fixed in WLS 7.0 ? I could not find this in the resolved bugs
          list for WLS 7 SP1. If this has not been fixed in 7.0, any idea when
          this fix would make it to WLS 7.0 ?
          Any pointers would be of great help.
          Thanks,
          Jeeji.

Is it possible to connect a servlet on WLS 6.1 to a server WLE 4.5?

Hi all,
Is it possible to connect a servlet java client on WLS 6.1 to a server CORBA
on WLE 4.5?
I have many problem, this connection doesn't!
The configuration is ok! But when the client java call
Tobj_Bootstrap bootstrap = BootstrapFactory.getClientContext("mypool");
the return is always null...
in the config.xml I define
<WLECConnectionPool MaximumPoolSize="5" MinimumPoolSize="2"
Name="mypool" PrimaryAddresses="//host:1570"
UserName="wrap" WLEDomain="wrap"/>
..the same code worked perfectly on the Web Logic Server 4.5...
Please help me!!!
Thank you very much!

These 'warnings' are usually pop-unders from a web page you've visited (i.e. they stay behind the page you're viewing so you don't see them until later).
They claim to have scanned your computer and found viruses: this is complete rubbish and a scam - aimed really at Windows users (the details given are often applicable only to windows).
You don't have any viruses: there are no Mac viruses in the wild. There are trojans and malware, but in all cases you have to actually install them (usually they try to make you think you are installing something else) and you would have had to give your admin password to do so.
You were right to stop the download. Never ever download or click any links on anything of this nature. Unless you have specific anti-virus software installed (which would identify itself in any warning) no warning of this nature can be genuine: it's an attempt to get you to install malware, some of which can be very nasty.

On Startup - Servlet to be invoked

Hi
When a Servlet is configured as load-on-startup, what is the life cycle it follows ? is it that only init() gets called?
How to invoke a Servlet/JSP when the Tomcat is started wihtout any user(manual) interaction? ie. would like to invoke on Startup.
Thanks in Advance

Yes, only the init() method gets called. What do you want to get called? It wouldn't make sense to call doPost() or doGet() as they would be expecting some context from the client site - i.e. the HttpServletRequest.
Would it be possible to call whatever you need at startup in the init() method?
Need Java help? Want to help people who do? Sit down with a cup of Java at the hotjoe forums.
Sure they're new - come get them started!

Weblogic startup servlet loading

Hi
I am encountering problems in loading a Servlet on Weblogic
server startup.
The steps to be followed to load 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 load my servlet on startup.
Any suggestions,solutions for the above problem
will be most welcome.
Thanx
Tapan.
