Allocate exception for servlet jsp

Hi everybody. I'm using appserver 7 2004q2UR3 on a linux box (RHEL 3). Sometimes, when we change some class or jsp included in a webapp, that application fails with the next error:
javax.servlet.ServletException: Cannot allocate servlet jsp because it is being unloaded
     at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:647)
     at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:229)

     at com.iplanet.ias.web.WebContainer.service(WebContainer.java:856)
This error sometimes makes the whole instance become unavailable.
When I get this error, I can oly stop and start the instance, but when I try to stop the instance I get:
[appserv@itaul4601 logs]$ asadmin stop-instance j2ee_server
Could not stop the instance
server failed to stop: abnormal subprocess termination
In spite of this error, the instance stops, and I can restart it without problems, but the problem may arise again after a while.
I don't know why this happens, and how to solve it. Any help would be appreciated.
Thanks in advance.

I have a similar problem and error. The only solution that work for me is restarting the PC and then starting tomcat.

Thanks for your help...
My servlet returns files, it has been working fine all the time but now I added the code below so I am getting an "Allocate exception for servlet" I have no idea what is this about as the servlet compiles successfully, could you help me to find the error?

                         baos.writeTo(out);
                         out.flush();


Here it is...

hi,
I just found that this exception is thrown from function
public UIViewRoot createView(FacesContext context, String viewId) {
UIViewRoot viewRoot = handler.createView(context, viewId);
context.getExternalContext().getRequestMap().put(CREATED_VIEW, viewId);
setupPageBean(context, viewRoot);
return viewRoot;
in viewHandlerImpl.java.
Has anyone got ideas about this???
Any help will be greatly appreciated.
cheers

No servlet class has been specified for servlet null

Hi,
I�m trying to bend tomcat in my own application. Therefore I�m using the Embedded Tomcat version 5.5.23.
I have started only a server, engine, host and context, so I have a server without the sockets etc. this because it has to become a test-application for the web-app of the company.
The server starts gracefully, but when I call context.invoke(request,response) I get this error:
SEVERE: Allocate exception for servlet null
With this stacktrace:
javax.servlet.ServletException: No servlet class has been specified for servlet null

at nl.realworks.embedTomcat.StartEmbedTomcat.main(StartEmbedTomcat.java:29)
does anyone has a idea what the cause of this problem is? The request I send is �GET /index.jsp� using a MockHttpServletRequest of the spring framework. I convert the mockhttpservletrequest to a org.apache.cataline.connecor.Request. and that works.
The code in tomcat where the error is caused by:
// Complain if no servlet class has been specified
if (actualClass == null) {
unavailable(null);
throw new ServletException
(sm.getString("standardWrapper.notClass", getName()));
Thanks in advance.

Yes , you are correct. We dont need to replicate DDIC tables for direct BW replication. This was the first time we were working with BW on Hana and never installed DMIS component on that system. The error was gone after we put the addon.

Hi,
Apparently changig the CLASSPATH did the trick.(changing path to servlet-api.jar)
We can view the JSP's in the WAR file now without exceptions, able to use the Logon.jsp page now.
Else, Thanks for the insight to looking inside the WAR file...
[root@msnweb webapps]# jar tvf optix-web.war | grep -i "api"

I just looked in the /Webapps dir where Tomcat extracted the *.war file and put the JSP's, that correct as well?

Hi,
I have an application which is executing properly in jboss 3.2.5 but as we are trying to upgrade the jboss version i am getting above mentioned error.

My guess would be that you have some of the servlet classes deployed with your application.
Yes.
Any jar files that contain the javax.servlet.* packages should NOT be part of a web application, but are intended to be on the server.
First up all there is no such jar files.
Common candidates:
servlet.jar
servlet-api.jar
j2ee.jar
All those jars are in lib directory of my app server. I have jsp-api and servlet-api.jar as i am using embedded tomcat 6 in jboss appsever.
Check the WEB-INF/lib directory of your web application to see that there are none of those there.
Nothing similar deployed in your ear file?I have extracted my application ear , jar and war then when i checked i found one jar file inside the war but in that no servlet*.jarr files. It is my application oriented files only. I have deleted this ar files and then i executedi am getting same error. Is there any way to find out the exact issue ????.

Null pointer exception when running JSP

I have recently configured a web application to run on a solaris 9 platform with an Oracle 10g database. I am using Sun One Web Server 6.1 SP4 as my web server. Most of my JSP's run fine but one of them is giving me the following error:
[29/Mar/2005:08:28:47] failure ( 961): for host 147.103.44.38 trying to GET /CI/searchSummary.jsp, service-j2ee reports: StandardWrapperValve[jsp]: WEB2792: Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at jsps.CI._searchSummary_jsp._jspService(_searchSummary_jsp.java:366) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at javax.servlet.http.HttpServlet.service(HttpServlet.java:908) at com.iplanet.ias.web.jsp.JspServlet$JspServletWrapper.service(JspServlet.java:675) at com.iplanet.ias.web.jsp.JspServlet.serviceJspFile(JspServlet.java:447) at com.iplanet.ias.web.jsp.JspServlet.service(JspServlet.java:363) at javax.servlet.http.HttpServlet.service(HttpServlet.java:908) at org.apache.catalina.core.StandardWrapperValve.invokeServletService(StandardWrapperValve.java:771) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:322) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:509) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:212) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:509) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:209) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:509) at com.iplanet.ias.web.connector.nsapi.NSAPIProcessor.process(NSAPIProcessor.java:161) at com.iplanet.ias.web.WebContainer.service(WebContainer.java:578)
I have not been able to determine the cause of this error since the line numbers in the error log refer to the servlet created when the JSP is interpreted insead of the line number in the JSP itself. Is there any way to correlate the error in the log with the actual JSP instead of the servlet that the interpreter creates? Any ideas as to what could cause this particular error? Any help would be greatly appreciated! Thanks!!!

Yes, you can look at the generated java servlet code under {http-instance}/ClassCache/{instance}/{web-app}/.../_searchSummary_jsp.java

Software Components Needed to Start Servlet/JSP development

Hi
Can you list what are the software components required to develop Servlets and JSP pages.

To practice with servlets and JSP pages you'll need:
- A server where you'll deploy your servlets and JSPs.
Download Tomcat: http://jakarta.apache.org/tomcat/index.html
- Tutorials for Servlets & JSPs: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
- Servlet API to compile your servlets. If using Tomcat look for the servlet.jar
in the installation directory under common/lib. You'll have to include this in your classpath.

Servlet-jsp.jar file

Hi
iam new to use jstl.i wrote on tag handler (java) class when i am compiling it is not identifying any of javax.jspexception ,java.jsp.tagext.
please help me what are all the jar files i have to have in class path or at any place and from where can i download them. i searched for servlet-jsp.jar,servlet-api.jar but i could not find anywhere in java.sun.com.any help is greatly appreciated
thanks

hi thanks for the reply. iam using tomcat 5.0
server. from where can i down load those jar files
please let me know
what jar files are needed if iam using tomcat 5.0 Like I said, Tomcat 5 uses Tomcat 5: servlet-api.jar jsp-api.jar. They will be in the server's classpath someplace. Look around were you installed TC. I am away from my machine at the moment so I can't say for sure, but it might be common/lib or shared/lib, something like that...
and
if weblogic 8.0Dunno. Look around the file structure.
Thanks for the help

Unwanted stack trace in weblogic.log for thrown JSP Exceptions

We are throwing a JSP exception within a custom tag when data validation
          errors occur; the errorPage for the JSP page is then invoked to show the
          appropriate errors. However, in the weblogic.log, a stack trace is shown
          indicating the exception (example below). We do not want this stack track
          shown unless there is a real "error" in our system vs. invoking the
          errorPage to show "application" errors. Is there any way to supress this,
          as we are not explicitly causing this to happen. It appears to be a
          weblogic feature. This causes us problems in finding true system errors
          that might be occurring due to these non-problems showing up in the
          weblogic.log.
          Thanks for the help.

The design of the data entry pages is such that the error page is the same
          page as the data entry page, and a validation JSP tag validates the data and
          if it finds a problem, it will set some variables and throw a JSP exception
          to redisplay the page. Unfortunately, we are forced to live with this
          design. Are you aware of any mechanism to suppress the automatic logging of
          thrown JSP exceptions in the weblogic log?

Need a good charting library (for use in a servlet/jsp environment)

Anyone know of a good charting library for use in a servlet/jsp environment.

Use JFreechart combined with cewolf.
www.object-refinery.com/jfreechart/
To use charts in a jsp page you can use cewolf ( a taglib) based on jfreechart.
http://cewolf.sourceforge.net/
Both are free.

Allocate exception for servlet jsp
