Servlet Error

Hi everyone, I cant sort this error I'm getting. It occurs when I make a call to read in an xml file from a servlet. Is is something to do with missing jar files? However when I call it from an ordinary java class it works fine. Therefore is it a server problem. I'm currently using tomcat
java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester
Thanking you in advance

The directory structure looks something like this (from Tomcat):
webapps -> app1
                  -> app2 (publicly accessible files in the document root)
                     |->WEB-INF (not publicly accessible)
                         |->classes (servlet & JSP classes that support the web app)
                         |->lib (supporting zip and jar files)
                         |->web.xml (deployment descriptor)

Any idea ???

Hello,
sorry for the late reply.
I have installed Apex Listener.1.0.2.238.15.24 on Oracle Containers for J2EE 10g standalone (10.1.3.1.1) That's a pretty old version of OC4J, and a pretty old one of APEX Listener, too. Is there any reason for not choosing a more recent release?
Despite that, your OC4J might also be using an unsupported (and outdated) Java version. APEX Listener needs at least a JDK 1.6 Update 20.
Please check whether your OC4J is using an appropriate JDK.

Report printing failed with "Servlet error: An exception occurred. "

Hi,
I use Apex 3.1 in Oracle Express edition develop few applications. In one of the application, when I enable report printing in stardard reports and try to print to PDF/Excel, the servlet error occur.
I had configured FOP in my server and I can download PDF in "interative report", but for stardard report, the report printing failed.
I can successfully print the reports in my others applications. Anyone know what could be the reason which cause an application failed to print the report.
Thanks
Vincent

Does your application name have special characters? I heard that the app name has to be just letters and numbers for this to work...actually testing right now.

Generated servlet error: method is undefined for type

Hi,
I keep getting the following error when I attempt to run my JSP:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /jsp-examples/JSPandMySQL/loginuser.jsp
Generated servlet error:
The method getValidUser() is undefined for the type LoginDetails
In my JSP file I have the code:
<%
boolean validName = login.getValidUser();
if(validName == false) {
out.println("Invalid Username");
} else {
out.println("Valid Username");
%>
and the method getValidUser(); is in a Java Bean that I have created and the code for that method is just :
public boolean getValidUser() {
return valid;
I've tried searching the net for some answers but none of the solutions given work for mine, I would be grateful for any advice on how to solve this program.

DId you import the class at the top of the jSP? Does the method exist? Is the class compiled properly?

500 Internal Server Error Servlet error: An exception occurred.

Hi All,
I was trying to access oracle applications. I installated R12 on Linux through VM Ware. I started Database Listener , Database and Finally Application Tier using adstrtal.sh. Every thing went fine with exit status as zero. I installed mozillla firefox and jre 1.6.0_07 but when I gave URL and tried to access applications i was getting 500 Internal server error.
Below is the error
500 Internal Server Error
Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details.

I've a situation that, we have to add some pages into the APPS environment. For that, what we generally do is,
1. Stop the Apache server.
2. Add the pages.
3. Start the Apache server again
And it should start.
But, In our case it's giving an internal server error.
And as we run autoconfig its working fine.But as it is a test server, we've got to add the pages several times. Each and every time we add pages we have to run autoconfig.
our environment is
OS: IBM AIX 6
APPS: release 11.5.10.2
we can't understand what the problem is!!!
Is the there any solution for that?
Please do suggest, if any one experienced the same...

OEM app server interface - Renderer failed: servlet error and NoClassDefFoundError

Hello, I am having problems accessing my OEM (running on Sun Solaris) in an XSession/ssh terminal window on my Windows machine. It was working fine for months, and now I get the following errors on the OEM web browser interface page. I was wondering if anyone has had this problem, or if someone from Oracle can suggest a fix for us? We are currently unable to re-start our live app server while this connection option is not working.
Thanks!

We also see this error message in the OEM webpage interface:
Servlet error: Renderer failed: java.lang.InternalError: Can't connect to X11 window server using '64.52.70.36:0.0' as the value of the DISPLAY variable
I am hoping this extra info might help someone who would like to give us a suggestion of how we can get the OEM to appear in our browser again. Thanks!!

Servlet Error An unexpected servlet error was encountered

I am getting the following error when I go to Oracle Application Server Welcome page and when I try to click on Logon to Oracle Application Server Portal I get the following error it was just working fine couple minutes ago... what may be the reason???
Servlet Error
An unexpected servlet error was encountered.
Please check the log file for more details

Hi,
It seems to be problem with your changed password of SSO/portal schema.
Could you be able to connect OEM.
http://<hostname_oem_is_up>:1810/ (default)
user name : ias_admin
password : xxxx
select your portal instance.
In bottom you can find the "Configure schema" link.
Change ur portal schema password over tre.
Imp :
Go back and click HTTP server --> PL/SQL Properties --> mod_plsql services --> DAD status --> Portal
Edit DAD: Database Connection --> Apply the same password u applied for portal schema
AT last restart ur HTTP server and try connecting to portal.

Interactive Reports: Servlet error when saving as Excel

Hi All
Environment: Apex 3.1, Database 10g 10.1.0.5, Oracle HTTP Server: OAS 10g Release 2 (10.1.2)
I'm getting the following error when trying to download an interactive report in Excel format.
Servlet error: An exception occurred.
The current application deployment descriptors do not allow for including it in this response.
Please consult the application log for details.
Can anyone shed light on this, I can't find any reference in the documentation?
Is there additional configuration needed on the HTTP Server?
Thanks
Mark

Check KM article id 1504257.1.
It says following solution :
1. On the FR server, navigate to Oracle \ Middleware \ EPMSystem11R1 \ products \ financialreporting \ bin.
2. Double-click FRConfig.cmd.
3. When the Java window (Java Monitoring & Management Console) pops up, click on the MBeans tab.
4. Expand com.hyperion > Financial Reporting > Attributes.
5. Locate the PrintServers entry. Remove any invalid server names from the Value field.
6. Stop and start the Hyperion Financial Reporting Web Application.
