Hi ,
I am also facing the same problem for compiling JSP Pages.
If the Flow of J2EE logic is HTM->JSP page then this works fine after deployement.
But if the presentation starts from JSP page then SUN Application Server8 is showing -
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.
     org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:132)

Can anyone kindly help in this ?

Urgent! Serious problem with J2EE Classloader!

Hi all,
I'm having a serious problem with j2ee Classloading.
I have "inherited" a J2EE application where all business classes (invoked by the EJB) are placed in the Application's Server classpath (Weblogic 8.1.4).
Very bad because every time a class is changed the a.s. must be restarted.
So I re-enginereed the package putting the business classes in a jar that is referenced by the EJB's MANIFEST file.
This way all the classes would be loaded by the EJB classloader and no need to start/stop weblogic.
Unfortunately it's not such !! I discovered that all business classes are loaded via REFLECTION
Object objCommand = objClass.newInstance();
Object[] param = new Object[1];
param[0] = aDataContainer;
objDataContainerReturn = (DataContainer) objMethod.invoke(objCommand,param);
and the application server cannot find them using the standard J2EE Classloader mechanism.
java.lang.reflect.InvocationTargetException

at irma.business.service.LoginService.login(LoginService.java:79)
On the other hand they're found if I put the classes on the application server classpath.
Has anybody got advice for this ? Should I refactor the application giving up reflection ?
Thanks a lot in advance.

Reflection uses the classloader as well so it should work fine.
A common cause of a NoClassDefFoundError is something in a parent classloader that refers to something only available in a child loader.
For instance, do you have any of your application classes which are in the $CLASSPATH but reference something that is only (now) in the business.jar in your ear?

Problem About J2EE RI and PetStore Demo

Hello ^^
I have a problem about j2ee & petstore.
I trird to set up sun j2ee RI 1.3.1 + pet store on win2000 or redhat.
Everything run ok. But when I changed web port 8000 to any port (included
80),
j2ee ri server showed the error message below :
java.net.ConnectException: Connection refused: connect
java.security.PrivilegedActionException: javax.servlet.ServletException:
An error occurred while evaluating custom action attribute "items" with
value "${catalog.categories.list}": An error occurred while getting
property "categories" from an instance of class
com.sun.j2ee.blueprints.catalog.client.CatalogHelper
I used root to start j2ee & cloudscape on linux,
and changed database to postgresql, too.
but the error is the same.
How to solve this problem ??
Thank you ~~
Jovi

Hi,
I dont know how useful my reply would be since the question was posted about 2 yrs back, but just wanted to reply in case somebody faces the same problem.
If you change the web port to some other port (other than 8000) then please check the sun-j2ee-ri.xml files. Actually the CatalogDAOSQL.xml is read using a url which includes the port you are running the server on. So, you need to change the port even in the sun-j2ee-ri.xml file.
One of the sun-j2ee-ri.xml files, where you need to make the change is in the $PETSTORE_HOME/src/apps/petstore/src/sun-j2ee-ri.xml file.
Other one is in $PETSTORE_HOME/src/apps/supplier/src/sun-j2ee-ri.xml file.
Look for other sun-j2ee-ri.xml files where the url is hardcoded. (I think the two sun-j2ee-ri.xml files mentioned above, are the only places you need to make the change, but still look for other files in case i have missed)
Change those urls and redeploy the ears.
Hope this solves the problem.

It appears that there is a file that is @ $J2EE_HOME/lib/security/secure.seed that is corrupted or empty. THE RI doesn't check if the file is valid. The solution is to delete the file and allow the RI to recreate the file.

WebSAPconsole - problem with J2EE

I am trying to install WebSAPconsole (GUI 6.40), but I have some problems with J2EE (SAPJ2EE620C_39-10001433.sar). OS is Win XP Pro Polish.
After instalation of J2EE I've tried to start dispatcher and server, and next check HTTP service - but there is no listening on 80 port, and there is no listening on p4 port (3011 - because of this no possibility to start visual administrator).
Dispatcher and server are listening on ports 2055 and 2077, and I have 2 java.exe processes in Task Manager...
No any other software occupying 80 and 3011 ports.
Any suggestions?

Problem reinstalling J2EE 1.4 on Windows XP

Hi everyone,
I installed once the j2ee 1.4 package without any problems, but I had to uninstall it.
Now during the last 3 days I've been trying to reinstall it, but everytime I try I got the same error during the installation process:
ERROR - default domain creation returned following exception: abnormal subprocess termination: Detailed Message:> was unexpected at this time.
was unexpected at this time.---------------------------------------------------------------------------------------
Can someone help me with this?
P.S.:
Everytime I have unistalled it, I have deleted the folder (C:\Sun) delete the "productregistry" and nothing seems to work.. Please help me!

Check your PATH environment variable - it is likely that > character referenced in the error message is coming from there. So, clean up that entry from the PATH and rerun the installation.

Crystal Report problem with J2EE - OutOfMemory

Please help .
Many Thanks

Hi,
It's a good idea to set the minimum and maximum heap size to the same value. In any case, don't let the minimum heap size exceed the maximum.
Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat.
Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used.
For example,
set CATALINA_OPTS="-Xms512m -Xmx512m" (Windows)
export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash)
setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh)
In catalina.bat or catallina.sh, you may have noticed CATALINA_OPTS, JAVA_OPTS,
or both can be used to specify Tomcat JVM options.
What is the difference between CATALINA_OPTS and JAVA_OPTS?
The name CATALINA_OPTS is specific for Tomcat servlet container,
whereas JAVA_OPTS may be used by other java applications (e.g., JBoss).
Since environment variables are shared by all applications, we don't want Tomcat to inadvertently pick up the JVM options intended for other apps. I prefer to use CATALINA_OPTS.
You have specified size by a capiital "M" ?(3072M) use "m".
Please let me know the results.

Neeraj

Problem creating j2ee web service

Hello. I'm having an issue deploying a given java class as a web service. I believe that problem is caused because, in the generated WSDL, the target namespace is set via the package name (i.e. http://myapplication.mycompany.com ), which is not a valid host. I tried changing every occurrence of that URL, in the WSDL, to the context root of my local host, but it still can't resolve the bindings. Given the following deployment message, what should my target namespace be:
(from OC4J startup):
Target URL -- http://localhost:8988/myApp-myProject-context-root/MyWebServiceSoapHttpPort
06/06/12 13:34:17 Web service MenuWebService has been started on the embedded server

Any help would be appreciated. Thanks. Take care.

here are the classes:

package com.test.service
public class MenuService {
    public MenuService() {
    public String echo(String payload) {
        return payload;

Jsp taglib problems in J2ee server of j2sdkee1.3

Fresh from solving the problems with usebean in jsp, I again got a problem with the custom tags of JSP
I am using Jdk1.3 and j2sdkee1.3, windows98

Pls help me to get through this hurdle
Thanks

1) To handle <bodycontent> you should inherit from BodyTagSupport
class
2) You should use your bean like: <td><atmjsp:ATM/></td>
with closing slash - it's bodyless tag - this mistake
causes JSP compiler to report error
Enjoy!

Hi Eray,
Congratulation!!! You got the solution!!!
The applications in Portal resides @ X:\usr\sap[SID]\JC00\j2ee\cluster\server0\apps\sap.com
Find your application there inside your application there will a WEB_INF directory.
Inside it there will be a folder named "classes" at this level create a folder named "lib" insert all your related lib files there and then after restarting the server you can check whether your problem is solved or not.
Let me know if the problem still exists!!!

Prashil

Double submission problem in J2EE application under Weblogic 8.1 SP2 server

Hi,
We are facing double submission problem in our J2EE application which is running under Weblogic 8.1 SP2 and for the same we already implemented or added the below preventive solutions.
1. We disable the SUBMIT button once the user clicks it.
2. We preventated pressing 'F5' button and clicking 'Refresh' button in the browser.
3. Also we tried to prevent by declaring the idempotent is 'true' under weblogic-ejb-jar.xml as below.
<stateless-bean-methods-are-idempotent>true</stateless-bean-methods-are-idempotent>
So please somebody help us on this issue like how to prevent in some other way.
Regards,
Dinesh.

I have no idea why you would think changing your EJB configuration would have anything to do with preventing double submission at your servlet layer.
One technique I've seen for preventing double submission was first used in the Struts framework several years ago. When a page is "prepared" for display, a token value is created and stored in the session. The page is displayed with a hidden field containing that value. When the page is submitted, the value of the hidden field is compared with the value stored in the session. If they're not equal, the submission is ignored.
