I think the tag <@page > contains some invalid directive, just check it out, if didn't get any, then if possible copy and paste the jsp file content in reply

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

Exception when running WLST in Eclipse - Please Help!!!

Hello,
I am trying to get get a WLST online connection via a java class, but I am getting an exception when trying to connect to an admin server instance:
<br>
<br><b>javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:

<br>
<br>
I am basically trying to run the following WLST command in java:
<b>connect('weblogic','weblogic','t3://localhost:7201')</b>
<br>
<br>
Here is the java block that I call to create the connection with the WLSTIterpreter:
<br>
<br>
<b>StringBuffer buffer = new StringBuffer();
buffer.append("connect('weblogic','weblogic','t3://localhost:7201')\n");     System.out.println(buffer.toString());
<br>
INTERPRETER.exec(buffer.toString());</b>
<br>
<br>
My admin server is running at this address and the CompatabilityMBeanServer is enabled. The strange thing this is that I am able to run the WLST via the command line and the connection is successful with no problems. This leads me to believe that there is something wrong with my classpath/environment that I have setup in Eclipse but I am not sure.
Any ideas on where I went wrong??? Please help!
Thanks :)
PS. I am running WebLogic 9.1 and java 150_06

i get an error saying ,unable to compile java compiler
iam able to compile servlets & execute them.
i have already set the paths for JAVA_HOME & CATALINA_HOME
please guide me accordingly
regards ,
shailesh

the same code gets executed in other system in which there is only one jdk.
the system which iam using has got many jre s due to
1) netbeans IDE
2)Weblogic server
3) jdk 1.4 was previously installed
4) jdk 1.5 was also installed
but i have set JAVA_HOME =jdk1.6
I doubt the compiler is trying to compile itself or another compiler

Try downloading any free app (you can delete it later). This will re-authorize the iTunes account on your phone and will often fix this issue.

Am not able to run the java program - pls help

1. I installed java in the below path
     c:\program files\java\jdk1.5.0
     c:\program files\java\jre1.5.0
I set the path in
     User variable i. variable name: path
          ii. variable value: c:\program files\java\jdk1.5.0\bin
when I compile it in command prompt-applying javac ? it performed successfully-shows
options like ?g create all debug info, -g : new Generate no debug info etc.,
But am not able to run the file. It shows error msg.
2. I specified the same name for file name & class name.
3. Java <class name>
     Exception in thread ?main?java.lang.NoclassDeffoundError: <class name>

     Exception in thread ?main?java.lang.NoclassDeffoundError: <class name>
7. I re-installed the java, but still the problem continuing.
pls help... its very urgent

Is the java class you compiled/calling in the default package? If it is not, you will have to call it by the fully qualified name.
e.g.
package com.mycompany.myproject;
public class MyClass {
    public static void main(String[] args) { }
}This would be called as "Java com.mycompany.myproject.MyClass" and must contain a main method with signature as above.
You would have to call this from folder where the compiled classes are located. If using package, you would call from directory at level of top most package so com folder in this example as Java will look at each package name in qualified name and try to traverse directories with those same names to get to .class file matching class name specified. To avoid this, your newly compiled .class files must also be in your classpath.
Hopefully that helps.

If you mean can you run it as a windows 2000 service so the user doesn't see it yes you can.
I recommend the following Java Service wrapper program:
http://www.eworksmart.com/JNT/
It's quite simple to set up and will start when the user logs in (so long as the service is set to start automatically).
Hope that helps,

How to run JSP in Tomcat

Hi i am new to java web application, i am running JSP(edited in notepad) in tomcat

i saved this jsp as first.jsp and D:\shyam\Apache Software Foundation\Tomcat 5.0\webapps\ROOT putting jsp in this folder.
then started tomcat webserver
then opeand browser giving URL: http://localhost:8080/first.jsp
the error coming like--> HTTP status 500
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
root cause:
unable to find a javac compiler;

Perhaps JAVA_HOME does not point to the JDK
Error coming like this, plz tell how to rectify this, I want to set any thing in web.xml, tell where i did mistake.

hi,
your problem is you didn't set java home in your path..
before running your application create a ".bat" file like,
set JAVA_HOME="path where you installed jdk eg: c:\jdk1.5";

Yes I have YemuZip & it works but need something that is either menu or automated. I have tried to use automator to automatically archive a .dat file when I add it to the folder where these files are stored...but can't get it to work. I haven't used automator before.
I have the workflow done but it will only run when I go to the menu & select the workflow - I though the whoel point was that it was automatic?
Anyway if YemuZip is the only way I can do it I guess I will have to wear it - I thought it may be a simple thing to alter the way OS X handles the compression...
Thanks!

Thank you Seyvet. I appreciate your help. You were right, I had to
change my
path to use java1.4.2. Now I run into another exception when I try to
configure
my authenticator from the console. Were you able to do this successfully?
Please
see my latest post if you think you can help. Thanks!! Sincerely,

I remembered that I had to sett eh following in ant to build:

And I suggest you check that ${java.class.path} is set properly.
<java classname="weblogic.management.commo.WebLogicMBeanMaker"
fork="true"
failonerror="true">
<jvmarg line="-Dfiles=${dir.mbean.temp} -DMDF=${dir.mbean.temp}/YourAuthenticator.xml

This may be a failure again, but did your check the java version you
are using
for compilation?
java -version
You should run JDK1.4.1_03 at least.
Personaly, I use 1.4.2_02-b03.

Null pointer exception when running OAF page

Hi
I am getting null pointer exception when i execute the code below.
OAApplicationModule am = oapagecontext.getRootApplicationModule();
OAApplicationModuleImpl childam = (OAApplicationModuleImpl)am.findApplicationModule("QuestAnswerAM");
oapagecontext.putDialogMessage(new OAException("PER", "XXOM_APPR_OVR_NULL_MSG"+am+childam, null, OAException.ERROR, null));
OAViewObjectImpl VO= (OAViewObjectImpl)childam.findViewObject("QuestDetailsVO") ;
OAViewRowImpl Dff1Row = (OAViewRowImpl)VO.getCurrentRow();
quest = Dff1Row.getAttribute("LastUpdateDate");
I later commented out the last 3 lines and used the code below to track the application module name.
OAApplicationModule am = oapagecontext.getRootApplicationModule();
OAApplicationModuleImpl childam = (OAApplicationModuleImpl)am.findApplicationModule("QuestAnswerAM");
oapagecontext.putDialogMessage(new OAException("PER", "XXOM_APPR_OVR_NULL_MSG"+am+childam, null, OAException.ERROR, null));
When i run the page i am getting this error:
Message not found. Application: PER, Message Name: XXOM_APPR_OVR_NULL_MSGoracle.apps.per.selfservice.appraisals.server.AppraisalsAMImpl@2982bfnull.
the above error indicates that the Root application module is AppraisalsAMImpl.
But the view i need that is QuestDetailsVO exists in a child AM that is QuestAnswerAM. However in the above diag message as you can see it returns child AM to be null.
When i click on About this page it clearly says that the QuestDetailsVO exists in QuestAnswerAM
Please help
Thanks

Hi
Thanks for the quick response.
I am fine with the error message:
Message not found. Application: PER, Message Name: XXOM_APPR_OVR_NULL_MSGoracle.apps.per.selfservice.appraisals.server.AppraisalsAMImpl@2982bfnull.
I am getting message not found becos I have registered only XXOM_APPR_OVR_NULL_MSG and am displaying '+am+childam' also in the exception which is not associated with the registered message.
See below.
oapagecontext.putDialogMessage(new OAException("PER", "XXOM_APPR_OVR_NULL_MSG"+am+childam, null, OAException.ERROR, null));
I am fine with that. My concern is in the error above for 'am' part i am getting the root appl module name. but for childam i am getting null
Message not found. Application: PER, Message Name: XXOM_APPR_OVR_NULL_MSGoracle.apps.per.selfservice.appraisals.server.AppraisalsAMImpl@2982bf*null*.
See the high lighted.
I will look into the current row returning -1 issue and get back to you./
Thanks

Exception when using RMI in tomcat 5.5, after reloading webapp

When I freshly start tomcat and deploy my web app, I can use RMI by creating a local registry and binding my objects.
However, as soon as I reload the web application, RMI no longer works and gives me this exception:

                    .getRMIResource("127.0.0.1", 1099));Trying set a RMISecurityManager breaks tomcat horribly by the way, but since RMI works with a fresh tomcat startup, I suppose there's no problems there.

Hi all!
I get the same Exception using Tomcat 5.5. When registering an object outside tomcat lookup works fine. Only when registering an object inside a webapp!
Would be great if anyone got a tip to solve it!
Greetings...

Exception when running JSP on Tomcat!Pls help me!
