Servlet in WebLogic Server 6.0

I am trying to run a servlet from WebLogic Server 6.0
 Copied servlet class file into the following directory:
 config/mydomain/applications/
 DefaultWebApp_myserver/
 WEB-INF/classes
 Modified the web.xml file located in the config/mydomain/applications/
 DefaultWebApp_myserver/
 WEB-INF/ directory
 <web-app>
 <servlet>
 <servlet-name>
 CustLogin
 </servlet-name>
 <servlet-class>
 lawson.servlet.CustLogin
 </servlet-class>
 <init-param>
 <param-name>url</param-name>
 <param-value> http:/localhost:7001/CustLogin/custaddr.html</param-value>
 </init-param>
 </servlet>
 <servlet-mapping>
 <servlet-name>
 CustLogin
 </servlet-name>
 <url-pattern>
 /CustLogin/*
 </url-pattern>
 </servlet-mapping>
 </web-app>
 Run servlet from a Web browser with URL:
 http://localhost:7001/CustLogin
 Servlet Exception
 <<Error> <HTTP> <saluki2> <myserver> <ExecuteThread-11> <> <> <101018>
 <[WebAppServletContext(944251,DefaultWebApp_myserver)] Servlet
 failed with ServletException>
 javax.servlet.ServletException: Servlet class: 'lawson.servlet.CustLogin'
 could not be resolved - a class upon which this class depends wasn't
 found

Deepak,
 Are all the classes used by CustLogin in System Classpath or under
 web-inf\classes directory?

Using servlet in weblogic server

hi, guys,
I have done quite a few research about using servlet in weblogic server, but still can't get it work, hope you guys can provide some suggestion. Thank you in advance.
I have a folder structure like this:
There is a "Jsp" folder under the "WebContent", and there is a configJsp.jsp file inside this folder, which is: 
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
<title>Insert title here </title> 
</head> 
<body> 
<form method="POST" action="Config"> 
<input type="text" name="myText"/> 
<input type="submit" name="mySubmit" value="submit"> 
</form> 
</body> 
</html> 
And then under the "Java Resources", there is a "servlet" package, there is a ConfigServlet.java file inside, which is like this:
 
package servlet; 
 
import java.io.*; 
import javax.servlet.*; 
import javax.servlet.http.*; 
public class ConfigServlet extends HttpServlet 
{ 
public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException 
{ 
doPost(request, response); 
} 
 
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException 
{ 
String textContent=request.getParameter("myText"); 
response.setContentType("text/html"); 
PrintWriter out = response.getWriter(); 
out.println(" <html>"); 
out.println(" <head> <title>ServletCommit </title> </head>"); 
out.println(" <body>"); 
out.println(textContent); 
out.println(" </body> </html>"); 
} 
} 
and I add the following mapping configuration into web.xml:
<servlet> 
<servlet-name>Config </servlet-name> 
<servlet-class>servlet.ConfigServlet </servlet-class> 
</servlet> 
<servlet-mapping> 
<servlet-name>Config </servlet-name> 
<url-pattern>/Jsp/* </url-pattern> 
</servlet-mapping> 
I run the application, click "submit", and got the following error message: 
Error 404--Not Found 
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found 
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. 
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. 
I guess there might be something wrong with the jsp and servlet mapping, but don't know what exactly it is, and have tried to change some configuration as well, but they don't work. This has annoyed me for a few days, hope there is someone who can be so kind to help me out of this. Thank you again.

to james.bayer: 
I tried modifying my web.xml like the following: 
<servlet> 
<servlet-name>Config</servlet-name> 
<servlet-class>servlet.ConfigServlet</servlet-class> 
</servlet> 
<servlet-mapping> 
<servlet-name>Config</servlet-name> 
<url-pattern>/Config</url-pattern> 
</servlet-mapping> 
is that what you mean? but the same error appear again, it doesn't seem to be able to find the servlet. 
I am using an BEA workshop for weblogic platform 10.0. Actually, I am trying to develop a portal, and I need a jsp to be included in it, and will need to deal with the form submit. The jsp is under a portal application, does it matter? Or is it different with a normal dynamic web application? Thank you for your advice.

Servlet on weblogic server

hi,

Your code does not seems to contain any reference to a file - see http://docs.oracle.com/cd/E23943_01/doc.1111/e10807/c23_ridc.htm#CIHCHACB on how CHECKIN_UNIVERSAL can be called. Are you trying to check-in a metadata-only item?
It'd also help if you share what parameters contain 'null' values (apparently, security group must contain something else).
Finally, I don't think it is a UCM-related problem. if you don't use a binder (requestBinder), but store values to standard strings, and try to trace them before ServiceResponse binderResponse;
try {
binderResponse = client.sendRequest(context, requestBinder);
requestBinder = binderResponse.getResponseAsBinder();
documentId = requestBinder.getLocalData().getInteger("dID");
} (before any UCM code is called, actually) it'll have the same values.

How to deploy a war file on Weblogic Server 7.0??

Hello Everyone
I am trying to deploy a servlet on Weblogic Server 7.0 as a WAR file. Can anyone of u plz tell me the steps required to do that. I am posting this question on EJb forum and not on servlets coz this is not a servlet problem, rather this is something which is related to J2EE, ie how to deploy a war file on J2EE Server.
This is how i have done it, but this is not working---
(1) First i created a directory structure for the web application according to J2EE Specification.
C:\Work\
myServletWAR\
META-INF\
WEB-INF\
classes\
HelloServlet.class
web.xml
i.e within work directory, there is a dic called myServletWAR which is my application directory which contains 2 sub directories viz META-INF which contains the mainifest file being generated by the jar utility. the second directory in the myServletWAR application dir is WEB-INF, which contains one file called web.xml for servlet mapping and one directory classes which contains HelloServlet.class
(2) I used following command for creating war file from myServletWAR director(i.e from my web application's directory).
jar -cvf TestServletWAR.war .
This creates the TestServletWAR.war file in myServletWAR dir.
Here is how my Servlet and web.xml looks like...
Servlet code
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloServlet extends HttpServlet
public void doPost ( HttpServletRequest req, HttpServletResponse res )
throws IOException, ServletException
doGet( req, res );
public void doGet ( HttpServletRequest req, HttpServletResponse res )
throws IOException, ServletException
res.setContentType( "text/html" ); // Can also use "text/plain" or others.
PrintWriter out = res.getWriter();
// Get the requestor's IP address (See JavaDocs to see how to get other info):
String addr = req.getRemoteAddr();
// Create output (the response):
out.println( "<HTML><HEAD><TITLE>HelloServlet in myServletWAR</TITLE></HEAD>" );
out.println( "<BODY><H1 ALIGN=\"CENTER\">" );
out.println( "Hello " + addr + ", from HelloServlet in myServletWAR!" );
out.println( "</H1></BODY></HTML>" );
out.close();

http://localhost:7001/myServletWAR/myHello
I am getting the HTTP 404 Error, which is an indication that weblogic was unable to find the resourse, which it was requested for. Can anybody plz tell me what i m doing worng?? do i need to use weblogic related xml file (i.e weblogic.xml) also along with web.xml. If yes, then what all i need to include that. I m not very sure. A sample weblogic.xml file for this HelloWorld example will help me a lot.
Looking forward for your help
Thanx in advance

WebLogic Server vs Embedded Servlet Engine

We have licensing for WebLogic Server, and I was wondering if there were any benefits to using it over the embedded servlet engine for hosting Collaboration 4.5 or Publisher 6.4?

hi.
WebLogic Express supports the following:
Servlets, JSP, JDBC, JNDI, JTA, JAAS, JAXP, RMI, and clustering. You
can build a cluster of WLExpress instances.
Hope this helps,
Michael
Laurent PAILLARD wrote:
What are the differences between Server and Express. I've read that
Express does not implement EJB, JMS and two-phase commit protocol for
transaction. Nothing is said about clustering. As Servlet session can
be clustered, I wish to know if I can build a cluster with 2 Weblogic
Express instances.--

JoltConnectionPool can not start in weblogic server

Hi
I am trying to run the sample Tuxedo provided application which uses Servlets or Ejb.
Now the Tuxedo Server has been configured and running properly.
I have WebLogic Server installed and had created the JoltSessionPool with name "MAJoltConnectionPool" and had also defined the StartupClass & ShutdonClass.
While defining the JoltSessionPool i had given min services as 1 and max services as 5 and others as default,
and the JoltSessionPool's target is a weblogic managed server which named ct2.
Then i tryed to start the ct2 server on command line such as:
startManagedWebLogic.cmd ct2 http://localhost:7001
I got an error in starting "MAJoltConnectionPool" but the server ct2 is starting normally.
Anyone who can help me to find out the reason? Thanks a lot.
The Command Line window shown following in the Log:

Hi
To resolve this problem , you have 2 solutions:
- modify the config.xml file to add in the tag <security-configuration> the following line :
<clear-text-credential-access-enabled>true</clear-text-credential-access-enabled>
or
- check the checkbox "Clear Text Credential Access Enabled" in the settings for the domain / security / general / advanced
restart the weblogic server to activate this change if necessary (Normaly, no restarts are necessary with weblogic server v10.3.5.0)
Hope this reponse help you (if it's not too late ;-) )

Hi jmendelak,
In the warfile i have jsp,servlets,java classes.
In my working directory i have jsp and html files and in web-inf folder i have a folder by name classes in which i have the servlets and java classes.
I made the war file and when i tried to deploy i was getting this error.
I had previously deployed this war file on weblogic6.1 it was working fine.
I have upgraded my operating sytem to Windows2000 professional from WinNT 4.0.I reinstalled the weblogic again and had set up the environment variables.
After going through the error could you find out the reason?Is it because some seeting is missing?

Error when starting Weblogic server

Wizards,
I installed the OPA Siebel connector. I had it working just fine for a while. I even added a new rulebase into the war and it was fine. As part of the implementation I am trying to add a new plugin to automatically save data at the end of the interview. I looked at the documentation and found we have to implement a specific event handler. After I added my jar into the plugins directory in the WAR, I am getting the following error, which seems to have nothing to do with my plugin. Can someone please tell me why this is occurring and how I can get the Weblogic server to recognize the plugins directory within the WAR?

Ian,
Thanks for your response. I have the following in my application.properties file:
plugin.libraries=com.oracle.determinations.web.siebel.SiebelDataAdapter;com.oracle.determinations.web.siebel.PreseedOnSessionCreatedHandler;com.sample.userplugins.automation.SessionSubmitTrigger
Additionally, I have placed the SessionSubmitTrigger class within a JAR in the plugins directory within the war. I am using Oracle WebLogic 10.3 as the app server to deploy the war within the AdminServer. And I am using OPA 10.4.3.
I should mention that the first two entries in the plugin.libraries property were there already as part of the Siebel Connector install. I just added the third one for OnInvestigationEndedEventHandler implementation.
I don't understand why Weblogic complains about not finding the Plugins directory. it is in my war. And despite the warning, I can access and navigate through my rulebase. It just doesn't seem to handle the OnInvestigationEndedEvent.
Thanks.
Sam
