yes they are right ,

bea.home=${env.BEA_HOME} weblogic.home=${bea.home}/wlserver_10.3
are set in "env.properties" & "env.properties" is in main folder(where all files are present).

Paul Sturrock wrote:I'm assuming the typo in the second one is not in the real file, yes?

can't get it , please elaborate

i am a bit confused , how to set a path.
i set as in the code below but still i cannot use the classes bundled in the "weblogic.jar" and "com.bea.core.descriptor.wl_1.1.0.0.jar" .

after googling , i got the below two code snippets but neither is working for me:

<path id="j2ee.classpath"> <pathelement location="${weblogic.home}/server/lib/weblogic.jar"/> <pathelement location="${bea.home}/modules/com.bea.core.descriptor.wl_1.1.0.0.jar" /> </path>

and


<path id="j2ee.classpath"> <fileset dir="${bea.home}/wlserver_10.3/server/lib"> <include name="*.jar" /> </fileset> </path>

weblogic.home and bea.home are set correctly.

it looks as if fileset & pathelement location does the same work.
i know the code is right but in my case its not working ,can anyone figure out why its not working in my case.

i migrated from Bea Weblogic 8.1 to Oracle Weblogic 10.3 . i could not find weblogic builder tool.
Is it there in 10.3 version or not ???

i was unable to find a install file for sun studio creator for windows XP.is there no install for XP.

i checked out there but no option for XP os.

apart from this other jars are needed and are placed in lib folder of the web-container/server you are using .

i wrote this code so that "cachedrowset -- crs" (i got from the "resultset -- rs") can be changed according to the condn specified and the modified cachedrowset will be updated in the oracle database.

condn. is when " name=sanjiv" it will change it to "rajiv" both in cachedrowset and database , it is changed in the cachedrowset (according to output below) but NOT changed in the database.

the output is

tushar--100000 sanjiv--890000 rajesh--790000 tushar--100000 rajiv--7900 rajesh--790000

strange thing is it is not reflected in oracle database even after line 39

I was trying to execute the jaasacn application provided here:
http://java.sun.com/javase/6/docs/technotes/guides/security/jgss/tutorials/AcnOnly.html#RunAc

i am stuck with the realm & kdc . how can i find the realm & kdc

my code is :
"welcome2.java"
import java.io.* ; import javax.servlet.* ; import javax.servlet.http.*; public class welcome2 extends HttpServlet{ public void doPost(HttpServletRequest request,HttpServletResponse response)throws IOException,ServletException{ response.setContentType("text/html"); PrintWriter out=response.getWriter(); RequestDispatcher dispatcher = request.getRequestDispatcher("/servlet/myspace"); dispatcher.forward(request,response); } }

whenever i am calling this servlet code from my jsp file :
"welcome1.jsp"
<html> <form action="/servlet/welcome2" method="Post"> <input type="submit" name="submit" value="clickme"/> </form> </html>

it is showing "servlet exception"

javax.servlet.ServletException: Servlet execution threw an exception welcome2.doPost(welcome2.java:10) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

showing this a 100-200 times then a "stackoverflow error".

if i put a stacktrace , it is giving :


at welcome2.doPost(welcome2.java:10) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:646) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:436) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:374) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:302)

is there a method to get the root cause of the servlet exception , how can i know the exact cause of the exception.
it looks as if a infinite loop is at line 10 in the servlet .
please help me.

i am testing so i have put it there.


in logfiles @line 14 ,it says "exception starting filter logfilter". i think something is here..(not sure)

i was trying out an example on filter but got a few errors that said:
SEVERE: Error filterStart Dec 22, 2009 4:56:23 PM org.apache.catalina.core.StandardContext start SEVERE: Context [] startup failed due to previous errors

i checked the log files and got this :

as the error says i do not have "LogFilter" class in "net.tushar" directory , but i have it.


my "web.xml" code is:

"LogFilter" code

package net.tushar; import javax.servlet.*; import javax.servlet.http.*; import javax.servlet.Filter; import javax.servlet.FilterConfig; import javax.servlet.FilterChain; import java.io.*; import java.util.*; public class LogFilter implements Filter { public void doFilter(ServletRequest req,ServletResponse res,FilterChain chain)throws ServletException,IOException{ try{ HttpServletRequest request = (HttpServletRequest) req; String ip = request.getRemoteAddr(); System.out.println("remote addr:"+ip+"date is :"+new Date().toString()); System.out.println("within request"); System.out.println("filtering request"); chain.doFilter(req,res); System.out.println("remote addr:"+ip+"date is :"+new Date().toString()); System.out.println("within response"); System.out.println("filtering response"); } catch(IOException ioe){ System.out.println("IOException raised :"); } catch(ServletException se){ System.out.println("ServletException raised"); } } public void init(FilterConfig config)throws ServletException{ String testParam = config.getInitParameter("test-param"); System.out.println("Test Param: " + testParam); } public void destroy(){ } }

i am not sure but i think the culprit is "filter-class" declaration.

you can , but its an older way .

matias casal wrote:How should I call the session in the jsp ?

by using custom tags,jstl or by scriptlets(not preferred)
using EL : simply put ${variablename} - you get the session variable

using scriplets(again not preferred but you can do it)

<% String var1 = session.getAttribute("variablename");%>

matias casal wrote: I am using this in a jsp page ; request.sendRedirect("other.jsp");

its not "request.sendRedirect("other.jsp");" it is "response.sendRedirect("other.jsp");"

you can use this in your head instead :<meta http-equiv="refresh" content="3;url=yourpage.jsp">
