Debuging servlet on weblogic
I am trying to learn to debug servlet on weblogic . In one of the site it is written as
Locate startWSL.cmd and add the following variable DEBUG_OPTS:
set DEBUG_OPTS = -Xdebug -Xrunjdwp:transport= dt_socket,address=1044,server=y,suspend=n
I am confused with this .Please tell me why is this necessary for debugging.
Thank you
Java uses the Java Platform Debugger Architecture to define how a Java debugger connects to a running Java application for the purpose of debugging that application. To enable an application for debugging, you have to add some parameters to the command line to specify a few things, like what transport will be used to transfer data, and if a socket-based transport, what port number should be used. Once you define those parameters on the command line and the application is running, you can specify the port number in the debug configuration of your debugger to make a connection to that running application.
You can read more about the various debugging-related command line options on the following page, which is just part of the larger JPDA documentation:
[http://java.sun.com/javase/6/docs/technotes/guides/jpda/conninv.html]
If you peruse the documentation for your favorite debugger, you can find information about connecting to remote Java applications, and it should give you similar information.

Hi,
Does weblogic provide a debug environment like IBM Websphere which can
be used in some Java IDE, like Visual Age or Visaul Cafe?
If does, please tell me the URL link to documentation.
Thanks

{Q} Debuging Servlets with VCafe 4.0 using WebLogic as WEB server
Hi,
I am trying to set up VCafe 4.0 to debug servlets deployed on WebLogic 5.1.
I don't have any problem with default servlet debugging, but I don't know
how to tell VCafe that my WEB Server isWebLogic. Any ideas?
Greg Mirsky
What edition of VCafe is required?
Enterprise, Professional or standard. I am now using JBuilder and anyone has
experience comparing it with VCafe.

Does WLS support Debugging Servlets with JBuilder 3 ?
I have read all the news groups and it appears that WLS 4.5.1 does not
support debugging Servlets with Jbuilder 3.0.
I am using the trial version, does this matter ?
Or should I just buy another web server ?
JoeI think below documents will be helpful to you.
http://docs.oracle.com/cd/E23943_01/apirefs.1111/e13952/taskhelp/webservices/webservicesecurity/CreateDefaultWSSConfig.html
This document tell you that you can attach a weblogic webservice configuration using weblogic admin console.
After creating this configuration you need to updated this configuration as per the steps given under :
Use X.509 certificates to establish identity

Error while calling servlet in WebLogic
Hi,
We are trying to call servlet in WebLogic by using http://scrmskr.apac.nsroot.net:7801/forms/HelloWorldServlet URL and getting
below error.
========================================================================
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.

404 error while invoking servlet in weblogic 6.0
Hi,
When I try to invoke a servlet from weblogic 6.0, I am getting
404 error. I have copied the HelloWorldServlet class into defaultWebAppl_Server/WEB_INF/CLASSES
directory and when I invoke the HelloWorldservlet, its giving file
not found(404) error. I am doing exactly what has been given in
the "quick start to servlets" in weblogic 6.0. I am using Windows
NT.
I have also another problem when I use java utils.dbping to test
the connection to my oracle8.1.8, its giving licence file not found.
Could some one help me out from this.
Thanks in advance,
Ramu
Hi kumar,
I have been keep trying to solve that. After some time Suddenly
"Error 404" disappeared and instead "Error 500" came. Okay kumar,
here is what I am doing...
I have installed weblogic6.0(eval), oracle 8.1.6 on Windows NT4.0.
I have installed oracle Enterprise edition from CD "ORACLE 8.1.6
for NT".
I installed the weblogic under D: drive.
I did class path settings as given in documentation. But Iam not
sure whether I need to do any other class path settings.
I was able to run pet store application given in weblogic server.
I went to "quick start" section and ran HelloWorld.jsp page from
"DefaultWebApp_myServer" directory.
I was not able to run servlet program as per given in the "quick
start". I am getting
"Error 500---Internal server error"
The server encountered an unexpected condition which prevented
it from fulfilling the request"
I have modified the web.xml under WEB-INF of DefaultWebApp_myServer
as per given in the quick start.
Here is the quick start link For you reference(as what I talking
about)
http://edocs.beasys.com/wls/docs60/quickstart/quick_start.html
In the web.xml, I have given <servlet-class> as just HelloWorldServlet,
since I directly copied the file from some other examples directory.
But still I am getting 500 error.
Here is the url that I am invoking...Http://ramup:7001/quickStartServlet
Coming to your oracle connection test, I did exactly what you said.
kumar, I have executed the command
"D:\bea\wlserver6.0\config\mydomain>java -classpath %classpath%;D:\bea
utils.dbping ORACLE
>scott tiger TestDB"
Where TestDB is the database that I have created while installing,
but I am not aware of the instance you said.
Here is what I got after executing the command.
--------*******-------Pasting the ms-dos command results----**-
// This mode is superior, especially in serverside classes because
// it avoids DriverManager calls are class synchronized, and will
// bottleneck any other JDBC in the server, even already-running
// connections, because all JDBC drivers use DriverManager.println()
// to log info and exceptions, and that call is also class synchronized.
// For repeated connecting, a single driver instance can be re-used.
**** or ****
Class.forName("weblogic.jdbc.oci.Driver").newInstance();
java.sql.Connection conn =
DriverManager.getConnection("jdbc:weblogic:oracle:TestDB", "scott",
"tiger")
**** or ****
java.util.Properties props = new java.util.Properties();
props.put("user", "scott");
props.put("password", "tiger");
props.put("server", "TestDB");
Class.forName("weblogic.jdbc.oci.Driver").newInstance();
java.sql.Connection conn =
DriverManager.getConnection("jdbc:weblogic:oracle", props);
D:\bea\wlserver6.0\config\mydomain>
--------*******-------Pasting the ms-dos command results----**-
I think I have connection to database, thanks for your suggestion.
Kumar, I have not seen weblogic.properties file any where in D:\bea
directory.
Kumar, if you have some time can you jot down the classpath settings
and path settings for executing SERVLETS/EJB programs.
Thanks for helping me out..,

A problem with servlets with WebLogic 4.5.1 SP11
Hello,
We have developed a client that connects to servlets in WebLogic 4.5.1. Some of the servlets use sessions to store data, and they receive some parameters from the client to retrieve information from a database.
When we use WebLogic 4.5.1, everything works fine. However, when we upgrade it to Service Pack 11, we find a problem. If we make a servlet that receives some parameters, but it does no use sessions, everything is correct. If we make a servlet that does not receive any parameter, and we use sessions, we find no problem either. But if we make a servlet that receives parameters and uses sessions within the doPost() method, there is an exception when we call the method Request.getSession(true).
I would thank any help about this point, since I'm not sure if this is the result of a bug, or if there is a new parameter that we have to set in the file weblogic.properties, or any other reason.
The code of our servlet is as simple as follows:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException {
ObjectInputStream in = new ObjectInputStream(request.getInputStream());
String arg = null;
String arg2 = null;
String arg3 = null;
try{
arg = (String)in.readObject();
arg2 = (String)in.readObject();
arg3 = (String)in.readObject();
}catch(Exception e){
// Get the session and the counter param attribute
HttpSession session = request.getSession(true);
// WE GET THE EXCEPTION AT THIS POINT.
Integer ival = (Integer) session.getValue("simplesession.counter");
if (ival == null)
// Initialize the counter
ival = new Integer(1);
else
// Increment the counter
ival = new Integer(ival.intValue() + 1);
// Set the new attribute value in the session
session.putValue("simplesession.counter", ival);
// Output data
ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());
out.writeObject(ival);
out.close();
On the other hand, the client invokes the serlvets using the following code:
public int servletClient(String usuario,String password) {
int numero = 0;
try{
// Input parameters
Serializable[] objs = {"login",usuario, password};
// Invokes the servlet
ObjectInputStream in = ServletWriter.postObjects(urlServlet, objs); // SEE BELOW...
// Get the results
numero = ((Integer)in.readObject()).intValue();
in.close();
}catch(Exception e){
e.printStackTrace();
static public ObjectInputStream postObjects(URL servlet, Serializable objs[]) throws Exception
URLConnection con = servlet.openConnection();
con.setDoInput(true);
con.setDoOutput(true);
con.setUseCaches(false);
con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
// Write the arguments as post data
ObjectOutputStream out = new ObjectOutputStream(con.getOutputStream());
int numObjects = objs.length;
for (int x = 0; x < numObjects; x++) {
out.writeObject(objs[x]);
out.flush();
out.close();
return new ObjectInputStream( con.getInputStream() );
// THE CLIENT CODE FINISHES HERE
The exception we get is the following:
Mon Feb 21 13:47:41 GMT-02:00 2000:<E> <ServletContext-Servlets> Servlet failed with RuntimeException

Error 500 while deploying Servlets using Weblogic 5.1
hi,
i have followed all the intructions on how to run servlets in weblogic 5.1 server.
till yesterday i have done nearly 10 servlets which worked perfectly. but today
when i coded a new servlet and started running using internet explorer it gave
"Error 500--Internal Server Error
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.5.1 500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling
the request. "
can u please give me the solution .
regards,
anitha
how this newly coded servlet is different from the other servlets?
Http 500 errror means some "internal error" happened while processing your request.
Do you see any error messages or stack trace on the server console?

Patchset3 (11.1.1.4/wls 10.3.4) Remote debugging JDPA in weblogic cluster
Hi,
I am using Patchset3 (JDeveloper 11.1.1.4/ weblogic server 10.3.4). I was wondering how i can remote debug with
a) weblogic managed server that is part of a weblogic cluster
b) the cluster itself that contains multiple managed servers.
Note that i do understand how to remote debug against a weblogic server (e.g. http://jdeveloperfaq.blogspot.com/2009/12/faq-4-how-to-remote-debug-adf.html), but have not been able to find out how i can achieve this against a cluster that has multiple managed servers. Any directions will be appreciated.
Thanks,Hi,
haven't tried it but here are some suggestions that might be of help:
1) Each managed server for each cluster node should be setup for remote debugging. This means that each managed server must be started with the -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n* options in the WebLogic start-up script. Also Tunneling must be enabled for each managed server for each cluster node.
2) Make sure that you specify a different connection port for each managed server. This is indicated by the address* specifier above.
3) It seems logical to me that you will need to start separate instances of JDeveloper - one for each managed server that you need to attach to.
Let us know how it turns out,

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

Deploying Servlets in Weblogic 8.1
Hi,
I have deployed servlets in Weblogic 8.1 server. The deployment was successful, but when I try to access the servlet it gives me java.lang.UnsupportedClassVersionError. It also says that it is unable to find the servlet class.
Can anyone help me with this?
Regards
Ushahi
can u check your supported configuration
this might because of incompatable JDK
a method writeObject(ObjectOutputStream) must be implemented in UTCDate to cover the JDK implementation difference of java.util.TimeZone between jdk 1.3.x and jdk 1.4.x. This is required to cover the member 'localeTimeZone' in UTCDate. Please refer to the source code of java.util.Calendar.writeObject(ObjectOutputStream) for an equivalent implementation for the member 'zone'.

Remote debugging the Oracle weblogic 10.3.3 from eclipse
As I see the startWeblogic.cml, I am finding it totally different frim the earlier scripts. I need to do remote debugging of the weblogic 10.3.3 from eclipse. Can someone guide me. Here below is the script of startweblogic.cmd I am finding on the oracle weblogic server. Need help as I need to do the remote debugging.

6. @rem JAVA_HOME - Location of the version of Java used to start WebLogic
7. @rem Server. This variable must point to the root directory of a
