Executing Servlets thru Tomcat 5.5.17.

I have just installet Tomcat 5.5.17 in order to execute Servlets.
Though the service is running,I am unable to access it.
When I say:
http://localhost:8080
it prompts me with a username and password screen:
I enter 'admin' as the user name and password is blank:
but am unable to go to the tomcat page.
Has anyone encountered this before?
I even tried entering 'tomcat' as user and 'tomcat' as password.

I enter 'admin' as the user name and password is
blank:
but am unable to go to the tomcat page.
Has anyone encountered this before?
I even tried entering 'tomcat' as user and 'tomcat'
as password.How about admin/admin?
Anyway, those credentials should be there, in some xml configuration file (admin.xml ? -- don't remember).

Dear Group,
I am using Tomcat 4.1 and have the following directory structure:

Hello all,
Thank you for answering the question now the servlet gets executed.

servlet. If anyone have different idea pls post. Im

Steps to create your directory and work in Tomcat 4.1
1.     Create your directory in Tomcat�s webapps Directory.
-----If your tomcat is in d:\ the your directory may look
----- D:\tomcat\webapps\<your directory>
     ------E.g. �d:\tomcat\webapps\test�
2.     In the test directory you can your html files directly or you can create a
directory to hold html files.
     --------E.g. �d:\tomcat\webapps\test\first.html (OR)
-------E.g. �d:\tomcat\webapps\test\html-files\first.html�
3.     Create a folder called WEB-INF inside test
-------E.g. �d:\tomcat\webapps\test\WEB-INF
------ Under the WEB-INF folder put your web.xml file
4.     Create another folder named classes under the same test
----- E.g. �d:\tomcat\webapps\test\classes
----- Here you need to place your servlet classes
----- E.g. �d:\tomcat\webapps\test\classes\testServlet.class
5.     Start any browser that are java enabled
6.     Type �http://<machine name (or) IP add.>:8080/<your folder
name>/<html file>�
----     E.g. http://localhost:8080/test/ html-files/first.html
-----E.g.http://127.0.0.1:8080/test/html-files/first.html
7.     Click the component (button, label�) to enable servlet
8.     That�s all! Now you should get your servlet executed.

How to execute servlets in tomcat?

Hi,
I have compiled servlet file and tried to execute that file from root i.e. (http://localhost/'filename'....)as class file is in web-inf/classes.But it is executing from "http://localhost/servlet/" where is that servlet directory?
why all servlets executes from "servlet/" directory?
Please reply....
Thanx in advance.

I has the same problem, and my solution was to include a line in the tomcat-auto file foreach servlet i had.
Under
JkMount /MyApp/servlet/* ajp13
I set a line
JkMount /MyApp/MyServlet ajp13
and in the web.xml of my webapp i included a servlet mapping for the servlet:
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>MyPackage.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/MyServlet</url-pattern>
</servlet-mapping>
Then restarting tomcat and apache it worked.
One question i have is that tomcat-auto file it is supposed to be auto-generated by tomcat, but in my case it is not, each time i add an app in the webapps dir i have to add all the stuff in tomcat-auto file. Does anyone know how to autogenerate this file?

One thing struck me though:

Execute a servlet in tomcat

hai friends,
I am trying to execute a simple servlet in tomcat but I couldn't..
please help me

Can you execute the default Servlets in Tomcat which are found in the "Examples" folder ? http://localhost:<PORT NO>/examples/
If yes then try deploying your servlet in the examples folder and find out a file called "servlet.jar " in your server and set its classpath.
I hope that will work.

Exception while executing JSP in TOMCAT

Hi,
I am new to Tomcat 5.0. I saved the JSP file in webapps/root folder. I have JDK1.3.1 and JRE 1.4.1. When I am executing the jsp, I am getting the following exception.

If I remove JRE 1.4.1 and install previous version i.e. 1.3.1, the tomcat server is not starting. How do I proceed. I need help in executing servlets also. I copied the tools.jar file into the common/lib folder.
I am awaiting for the replies. Thanks in advance.
sampath

Hmmm. It seems that Tomcat is running on Java1.3, but trying to compile a JSP using Java1.4, which leads to problems.
What have you set your JAVA_HOME variables to?
Which version of Tools.jar did you copy to the common/lib folder?
How do you start up tomcat? Shortcut or service?
Copying Tools.jar is a bad thing to do in most cases (Yes, I know it told you to do that, but if it told you to format your harddrive would you do that too?) I would remove tools.jar, and see what happens then.
Good luck,

How to run a servlet in Tomcat 5.0 server

HI Everybody,
I want to know how to run the servlet file on my tomcat 5.0 server. that is where to place a class file and deployment details.

inside this create directories as follows :

                   |-----classes ( .class files. )[all of your java code should be placed here.](servlets / beans/ pojo )this is the general Directory structure of a web application. now you've to place the compiled .class file of your servlet in the "TestApp\WEB-INF\classes" directory. make sure that you've configured the servlet in Deploment Desctiptor, i.e, web.xml.
now start the server and type the url like : "http://localhost:8080/TestApp/TestServlet"
the port no. 8080 is the default port no. of tomcat. you have to give your port no. if u've modified it. and TestServlet is the <url-pattern> of your servlet.
go through some tutorials .. then you can easily know that

Error in executing servlet JSPRunner: java.lang.NullPointerException

I have some problems with my jsp files.
I am using iAS6sp4 and iWS 6 on W2K.
I created a EJB jar file and an empty WAR file (No JSP, Servlet, just web.xml & ias-web.xml) and pack them into a ear file for deployment. It was successful.
Then I copy some jsp files to <iasinstall>/ias6/ias/APPS/<app name>/<war name>
and restart the ias and iws server.
When I try the URL: "http://myserver/NASApp/<app name>/myjsp.jsp", I got this error message from kjs.
JSPRunner: init

My jsp didn't include any java code, just pure htm code. I want to give it a test. But even though I tried with a proper jsp i still got this message. pls advise.

Servlet on tomcat 4.1.18

I am facing a problem of running servlets on Tomcat 4.1.18. The problem seems to be in the configuration. In the webapps folder, I created a folder greeting. In that, the WEB-Inf\classes folder has GreetingServlet.class.
webapp\greeting has index.html that has to FORM ACTION set to /greeting/servlet/GreetingServlet.
On clicking the submit button the message I get is that the resource /greeting/servlet/GreetingServlet is not found.
Can anybody help in configuring the server so that the above mentioned servlet gets recognized?
Thanks.
Amitabh.
[email protected]

My application is located at %TOMCAT_HOME%\webapps.
%TOMCAT_HOME%\webapps\greeting\WEB-INF\web.xml has the following:
<web-app>
<servlet>
<servlet-name>greeting</servlet-name>
<servlet-class>GreetingServlet</servlet-class>
</servlet>
</web-app>
%TOMCAT_HOME%\webapps\greeting\index.html has the following:
<FORM ACTION="/greeting/servlet/GreetingServlet" METHOD="POST">
<P> Your name <INPUT TYPE="text" SIZE="40" NAME="name"></P>
</FORM>
Yet the problem persists.
Have I missed some point?
Help/assistance will be appreciated.
Thanks.

Servlets in Tomcat

I am trying to run servlets using Tomcat. I have them working and displaying but as soon as I make a change to a servelt and re-compile and refresh the browser the change do not take effect. I have to shutdown and restart tocat. Surely this can't be right. can anyone help with correcting this problem?

Lesta,
For convenience there's a Tomcat admin console. The admin console runs through a web browser and allows you to restart an application, restart a context ect. I think you can also install or reinstall entire ears through it now.
There's some setup to do before you can use the admin console. I seem to remember there being an XML user/password file somewhere...
In a production environment you don't want to shutdown and restart the daemon like you are doing. It will just annoy the heck out of your users.
Hope this helps.
