Tomcat 4.1.12: "java:comp not bound"?

[Sergei Batiuk]

Hello,

I have just downloaded the 4.1.12 version of Tomcat an trying to run an
web-app that was successfully run on Tomcat 4.0.3. However, during
datasource and environment entries lookups() from jndi I get the following
error:

org.apache.jasper.JasperException: Name java:comp is not bound in this
Context
at
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:2
48)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:289)
at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:240)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)


Does Tomcat 4.1.12 has broken jndi? What's wrong? Is there any solution?

Sincerely,
Sergei Batiuk.

As far as I know, -Djava.endorsed.dirs=... works only with jdk1.4, but you
seem to be using jdk 1.3.1_03.

Hi,

I am new to Jsp and Java stuff.  I installed Tomcat 4.0.4 following
instructions http://jakarta.apache.org/tomcat/tomcat-4.0-doc/RUNNING.txt

When I try to startup tomcat, I get the following:
C:\jakarta-tomcat-4.0.4\bin>startup
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
The system cannot find the batch label specified - end
Using CATALINA_BASE:   ..
Using CATALINA_HOME:   ..
Using CATALINA_TMPDIR: ..\temp
Using JAVA_HOME:   c:\jdk1.3.1_03\bin;
The system cannot find the file -Djava.endorsed.dirs=.

I have tried setting up environment variables for JAVA_HOME and
CATALINA_HOME but still get same error.
Please help.  Thanks in advance.

Manisha

RE: Closing Connections.

[Sergei Batiuk]

Hello,

It is a good practice to close all open connections with a JSP. Event though
connections will be eventually closed by Java garbage collector, while open
they consume valuable resources, such as memory and network traffic. To me
it not an option if I should close db connections - I always do that.

Sincerely,
Sergei Batiuk.

Hi All,

 Is it neccesary for us to close the connetions for the database. Is the
java garbage collector gonna do the job for us.

If that is not the case please tell me how to close the connections. We have
a application containing 800 pages . Every page has a connection open . Do
we require to close all the applications.

Regards, Hari Yellina.

RE: ASP and JSP with no redirection

[Sergei Batiuk]

There is an option:

You can use the io taglib from http://jakarta.apache.org/taglibs, which
makes it possible
to make up a page from various sources. Your JSP should look like:
<%@ taglib uri="iotags" prefix="io"%>

<%
myEJB.myMethod();
%>
http://iisServer/m$Page.asp"/>
<%
java().stuff().again();
%>

This way you can create a single page from any http/ftp/file resources you
can think of.

Sincerely,
Sergei Batiuk.

Subject: ASP and JSP with no redirection


Hi All,

Just wondering if there is another way to integrate both JSP and ASP
together in the one page without redirection through a specific port.

Is it possible to combine both an ASP and JSP page together thus giving you
the ability to access a COM and EJB object on the same page ?

I know this sounds crazy but if it is possible then I would imagine its
something that needs to  be configured at the web server level such that
each Object method request is handled by its respective web server.

foo.JSP
<%

 ... myEJBBean.Method() ...
 ...myASPObj.Method()...

%>

Lets say our example is implemented on a JSP page then Tomcat/Apache will
need to know about IIS such that it passes the processing of
"myASPObj.Method() " to IIS. (no redirection)

Many thanks in advance for any feedback.

Regards,
George Shafik

RE: Custom Authentication

[Sergei Batiuk]

Hello,


If you mean a 'Login API', it doesn't exist in Tomcat You need to use
form-based login instead.


There is "InitialContext" in Tomcat. This is how I used it to set up
DataSource ( Tomcat 4.1.0) :



  
  

useryour_login

passwordyour_password
driverClassName
  sun.jdbc.odbc.JdbcOdbcDriver
driverName
  jdbc:odbc:OkeanTest
  

    


Sincerely,
Sergei Batiuk.

Subject: Custom Authentication


Hi all! ;)

I have to migrate a Web Application from Allaire JRun to Tomcat 4.0.1.

I have a custom Authentication created by us. How can i use it under TomCat
4.0.1? Information is very non-existant or I'm just to dumb to find it!
:))

Another question: Do i have a "InitialContext" ? If i have so... where is
it? If it doesn't exist, it's no problemat all. I'll simply use the usual
method to access the MySQL database without aquiring the DataSources from
InitialContext (wich maybe it's something from J2EE).

Sorry for my poor English.

Thanks for any help you can give me! :)

Dynamic XML/XSLT with Tomcat 4.0

[Sergei Batiuk]

Hello,

I would like to use XML/XSLT in my project. The problem is that my XML pages
(and possibly XSLT pages) will be dynamic not static. I think, JSPs should
generate the content, but how do I tell Tomcat to process them with the XSLT
processor?

RE: Programmatic login with Tomcat 4.0.1

[Sergei Batiuk]

Well, but what about programmatic login, i. e. something like

  Context ctx = new InitialContext();
  UserManager um = ( UserManager )ctx.lookup( "java:comp/UserManager" );
  um.login( login, password );

Does Tomcat have an API similar to this? The thing is I have a login form on
my first page, where a user should login to access protected functions (they
are not displayed by default, and become available only after a user has
logged in).

If you use BASIC authentication, user/password are contained in the
"Authorization" HTTP 1.1 Header (in Base64 encoded form).
Never tried, but should work when supplying correct data into your HTTP
request (including headers).

Hello people,

I need to programmatically login my session into Tomcat 4.0.1 servlet

this goal.

How do I programmatically login into TC 4.0.1?
