Unable to Compile EJB Sample

Environment: Windows NT4, sp5, WLS 5.1/sp 2, Sun JDK1.2.2
As illustrated in 'Introduction to BEA Weblogic Server', pp 101-102, I'm
compiling the Emp EJB sample. I successfully compiled the java programs,
moved the XML files, and created the initial JAR file. Next the sample says
to run ejbc on the JAR file. When I do I get the following error:
G:\weblogic\examples\intro\ejbtemp>java -Dweblogic.home=%WL_HOME%
weblogic.ejbc Emp.jar -d %WL_HOME%\myserver\Emp.jar

Any idea what may be causing this?

try to use the build script in the examples directory..
It is available for all examples.
so after running setenv
go the example u want and run the build.cmd
it should work

Unable to compile EJB client program

Hi, I developed a simple client program to an entity bean and I am not able to compile. Following are the few lines picked up from the code: (all my ejb,home and remote classes are under "test" package)
import test.*;
import java.util.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
public class TestClient {
public static void main(String[] args) {
try {
Context initial = new InitialContext();
Object objRef = initial.lookup("MyTestBean");
TestHome home = (TestHome) PortableRemoteObject.narrow(objRef, TestHome.class);
... etc.
I am getting the following compilation error
TestClient.java:13: inconvertible types found : java.lang.Object required: TestHome
TestHome home = (TestHome) PortableRemoteObject.narrow(objRef, TestHome.cl
ass);
The classpath is set to j2ee.jar and the local working directory in which the package "test" resides.
Any help in this matter is greatly appreciated.
Thanks.

Greetings,
Hi there,
Did pengjuc's answer help you to solve this problem?
I'd be really interested to know if it did.Unlikely, since the error reported is not with the object reference but with the specified class type. Additionally, this approach is not recommended since it assumes the underlying protocol is always (RMI-)IIOP and not vendor specific - portability is lost.
Thanks

Error in starting an EAR containing EJBs : Unable to prepare EJB

I am using ANT build script to create and deploy EAR on WAS server.
This EAR file packages EJB jar file inside it.
I am using WAS 5.1.1 Test Environment from IBM RAD 6.0.
When deployment is done, the application is not in Started status.
If I try to start it from web-based admin console, I get error given below.
I examined the missing classes.
Error CNTR0075E could not find: EJSStatelessSurveyManagerHomeBean_a1e88e5e
Error WSVR0209E could not find: EJSStatelessSurveyManagerHomeBean_00693296
When I checked the deployed EAR file, I could locate EJSStatelessSurveyManagerHomeBean_a1e88e5e in the EJB jar file inside the EAR file. I carefully checked the full qualified name. It is there.
But the other one (classname ending with 00693296) is not there.
What are these numbers? Are these any ref ids in some xml file (web.xml, ejb-jar.xml, etc)?
When I searched web based forums for these error codes, I tried varius solutions [e.g. Generate Deploy Code and RMIC, etc] but nothing seems to work :-(
Is there any solution to it?
Thanking in advance.

Hi,
It seems one of your ejb jar is missing from the current file location.
D:\dev\workspaces\.metadata\.plugins\org.eclipse.core.resources\.projects\itr-ear\beadep\citron_domain\itr-ear\split_src
you can make it manually copied to this location and build the project again so that it can able to deploy propertly.
Now one more thing you can do open a ticket with oracle support for better assistance.

Kal

Unable to deploy EJB application

Hi iam getting the following exception while deploying an EJB application in WebLogic 8.1
Exception:weblogic.management.ApplicationException: prepare failed for Addition
Module: Addition Error: Exception preparing module: EJBModule(Addition,status=NEW)
Unable to deploy EJB: Addition.jar from Addition.jar:
Compiler failed executable.exec
at weblogic.ejb20.ejbc.EJBCompiler.doCompile(EJBCompiler.java:274)
at weblogic.ejb20.ejbc.EJBCompiler.compileEJB(EJBCompiler.java:468)

at weblogic.ejb20.deployer.EJBDeployer.runEJBC(EJBDeployer.java:493)
at weblogic.ejb20.deployer.EJBDeployer.compileJar(EJBDeployer.java:763)
what might be the reason for this exception ????

This problem is caused by the way WebLogic calls javac to compile the generated classes for the EJBs deployment. This became a big problem for our project with 50 Entity EJBs 2.0 with CMP/CMR, about 15 EJB-QL statements, 3 MDB and 8 Session EJB. I think that these numbers are limits, so exceeding any of these numbers cause javac to exhaust the memory it allocates by default. Even the WebLogic 8.1.Server's administarion console allows you to supply additional parameters for RMI and EJB compilers, it does not allow to supply the -J-Xmx256M (or more) option needed to increase the memory javac allocates.
Thus:
1. In the active $JAVA_HOME/bin of the Server create the file:
Windows:
javac1.cmd Containing:
javac -J-Xmx256M %*
Linux:
javac1.sh Containing:
#!/bin/bash
javac -J-Xmx256M $*
make it "executable"
NOTE: startWeblogic script sets it own JAVA_HOME, so check it first.
2. In the administraitve console of WebLogic 8.1 Server select the server in the left frame under the
<Domain> / Servers branch. In the right frame select the General tab.
3. In the Java Compiler box change javac to javac1.cmd or javac1.sh respectively. No restart is needed.
This solved our problem.
I could not find any solution published, hopefully this will help other colleagues.

}I read in one blog (actually - the only page which was returned by yahoo - so - this should be very rare error!!!) to try to use Sun server's verifier.bat - and - it reported 0 errors and 0 warning. Build was succesfull as well and also - deployment was without errors - but - above mentioned error appeared during the automatic compilation of jsp pages/servlet when newly deployed jsps are first accessed from remote browser.
So - is it possible, please, to receive some advice - what to do further? I feel that my invoice.jsp page can be with errors, - however - the original welcomeJSF.jsp should be working without errors even the erronwous JFS jsp page is added to web application.
Thans for any adice or hint in advance!!!

OK - I have made 'clean and build main project' from NB menu and the deployed the resulting *.war and the error messages have disappeared... So - it seems to be bug...

Unable to deploy EJB: CxAccount from apollo_adapter.jar: There is a mismatc

Hi all
We are using code compiled on wl8 sp3 on wl6 envt
Few days it worked fine then suddenly we are getting the below exception while restart of the server .The same code is working fine in other wl6 instance .
We cleared the cache and tried to restart the server but still getting the same exception.Just was wondering how come the same code works in one envt and gives this exception in other even though both have same environmental settings and DB.This code runs well in wl8 envt.I would appreciate any help in this regard

Unable to deploy EJB - NullPointerException

Hello,
We are migrating our application from WebLogic 8.1 to WebLogic 10.0.
We changed the deployment descriptors according WL 10.0 specs. The application deploys and activates seamlessly. The problem comes when we try to start it (for "Servicing all requests"):

The application worked just fine on WL 8.1. There are no changes in the code. The changes in the deployment descriptors are the minimum required to deploy the application on WL 10.0.
Any idea what can be the reason for this error?

Hello auspost_simon,
Thank you for your answer.
We always compile our project with Sun's Java (JDK) compiler. Up to now our application had to be compatible with other app.servers and we used only the WL Builder tool from v.8.1 to build the specific deployment descriptors. We searched for a similar tool in WL 10.0 but we didn't managed to find one.
We tried the migration tools supplied with WL 10.0 to migrate the deployment descriptors. The result of the EAR (EJB) with the migrated DDs is the same as the demonstrated.
Please be more specific - what do you mean by "WL 10.0 compilers and builders"? To be honest we are migrating to WL 10.0 on the fly - we have almost no time to read the docs, so any clue on "WL 10.0 compilers and builders" is appreciate.

Javax.naming.NameNotFoundException: Unable to resolve ejb-link.

Env: JDK 1.3.1_08
Weblogic: 7.0
We are attempting to use EJB's (session) and have it all localized in a jar.
The Business and Custom Logic is all compiled to WEB-INF/classes. All the jars including the EJB jar is under WEB-INF/lib.
On Startup Weblogic throws the error message
weblogic.management.ApplicationException: activate failed for application
Module Name: application, Error: weblogic.j2ee.DeploymentException: Could not setup environment - with nested exception:
[javax.naming.NameNotFoundException: Unable to resolve ejb-link. Appejb.jar#AppServerBean is not in the context. The context includes the following link bindings: {} Make sure the link reference is relative to the URI of the referencing module.]
I have tried using the ../ notation before the Appejb.jar in the web.xml and what not, but that does not work either.
I have sucesfully deployed the EJB jar through the weblogic console.
Any Clues or suggestions will be most appreciated..
thanks

Create a ear application from the ejb jar and web application war.
Copy ear application to the applications directory.
In the ejb-link element in web.xml specify the relative path to the ejb jar.
<ejb-link>../Appejb.jar</ejb-link>
thanks,
Deepak

Unable to compile class for JSP

Please can anyone help me to solve this.
Actually,this is the condition.
In my db,there is a table called UserPassword, which has 4
fields(empNo,UserName,password,level). Now I want to do these things:
When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
1)To check the empNo,if it is already exist in the DB,
     if empNo =exist then display error.(record already exist)
     if empNo =notexist then do task 2).
2)check the UserName,if it is already exist in the db,
     if UserName=exist then display error.(because it's a primary key)
     if UserName=notexist then do task 3).
3)Create a new user account and save it to the db.
To do these tasks,I never create a new objects for the tasks 1) and 2).
only for task 3)create an object.
Is it the right way?
Here is the file CreateAcc.jsp
<%@ page language="java" %>
<%@ page import="core.UserAccManager" %>
<%@ page import="data.UserPassword" %>
<jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
<jsp:setProperty name="UserAccManager" property="*"/>
<jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
<jsp:setProperty name="UserPassword" property="*"/>
<%
String nextPage ="MainForm.jsp";
if(UserPassword.verifyEmpno()){
     if(UserPassword.verifyUsername()){
          if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
      }else{
           nextPage="UserNameExist.jsp";
      else{
          nextPage="UserAccError.jsp";
%>
<jsp:forward page="<%=nextPage%>"/>The directory structure:
UserPassword.java- F:/Project/core/data/UserPassword.java
UserAccManager.java - F:/Project/core/UserAccManager.java
Now both are compiling.I put the class files into the TOMCAT,as follows.

Are there any mistakes? If so tell me where is it and how to change them.Please help.

I try it that way, but it don't compile.
Error:core\data\UserPassword.java:package javax.servlet does not exist
import javax.servlet.*;
core\data\UserPassword.java:package javax.servlet.http does not exist
import javax.servlet.http.*;
So,I comment them only in the UserPassword.java file,and compile it again.
Then it compile well.I goto the directory to get the .class files.
But there is only UserPassword.class inside the data folder. There is not
UserAccManager.class in the core folder.
Then I try this way,I put my 2 java files in to a new folder,
F:\SystemName\com
When I try it that way, but it don't compile.
javac -classpath . -d . com\*.javaError:com\UserPassword.java:package javax.servlet does not exist
import javax.servlet.*;
com\UserPassword.java:package javax.servlet.http does not exist
import javax.servlet.http.*;
So,I comment them only in the UserPassword.java file,and compile it again.
Now both are compiling well.There was 2 class files.
I put them in to the WEB-INF/classes/com directory.
Start the server.But it gave errors:

ER unable to compile using javac with java 1.3.1 library (JDEV 10.1.3.0.4)

Hi !
When I try to compile in JDev with javac and the java 1.3.1 library, I get the following error :
Error: javac: invalid flag: -source
The command line generated by JDev looks like :
C:\jdk1.3.1_03\bin\javac.exe -J-mx512m -verbose -deprecation -source 1.3 -target 1.3 -encoding Cp1252 -g -classpath [...] -sourcepath [...] -d [...] @C:\DOCUME~1\user\LOCALS~1\Temp\javac54193.tmp
It seems that -source and -target flags do not exist in this version of javac.
But it does not seem possible to remove these flags generated by JDev, so I'm unable to compile with javac 1.3.1 and JDev.
So i'm looking for :
- A workaround to prevent JDev from adding the -source and -target flags.
- A future release of JDev where you could disable these flags, or, much better, where JDev automatically disables these flags when it detects a 1.3.1 library (there may be other incompatible flags I did not mention).
Thank you for your answers :)

Hi,
when you open the project properties and choose the compiler option to tht the compiler to "javac" and then the "source" and "target" to 1.3, wouldn't this compile it for Java 3? I don't think that it is necesary to use JDK 1.3 for compiling the sources
Cross-Compilation Options
By default, classes are compiled against the bootstrap and extension classes of the platform that javac shipped with. But javac also supports cross-compiling, where classes are compiled against a bootstrap and extension classes of a different Java platform implementation. It is important to use -bootclasspath and -extdirs when cross-compiling; see Cross-Compilation Example below.
-target version
Generate class files that will work on VMs with the specified version. The default is to generate class files to be compatible with the 1.2 VM in the Java 2 SDK. The versions supported by javac in the Java 2 SDK are:
1.1
Ensure that generated class files will be compatible with 1.1 and VMs in the Java 2 SDK.
1.2
Generate class files that will run on VMs in the Java 2 SDK, v 1.2 and later, but will not run on 1.1 VMs. This is the default.
1.3
Generate class files that will run on VMs in the Java 2 SDK, v 1.3 and later, but will not run on 1.1 or 1.2 VMs.
1.4
Generate class files that are compatible only with 1.4 VMs.

Unable to compile servlet files in javac

i am unable to compile servlet *.java files in javac.as far as i can see my path is correct.
Kindly provide a solution as soon as possible.
My jdk1.3 is in my c drive and my tomcat in my d drive.
if you are able to compile kindly let me know your path.
it says symbol not resolved.i think that it is unable to import from javax

Assuming that your jdk is in c drive as c:\jdk1.3 set the path and the classpath like as shown below. Remember that you have to set the classpath for the classes in the javax.servlet and javax.servlet.http packages. I know how to do it for JavaWebServer. JavaWebServer has a jar called servlet.jar that contains all these classes. What you need to do is to put this jar file in your classpath. There will be a similar jar file for Tomcat server also. You need to refer the Tomcat server documentation for that.
The path and the classpath have to be set like this...
d:\>path=%path%;.;c:\jdk1.3\bin;
d:\>set classpath=%classpath%;.;c:\jdk1.3\lib;c:\JavaWebServer2.0\lib\servlet.jar;
assuming tht JWS is installed in c:\JavaWebServer2.0
Also note that there should be no spaces in between while setting the classpath. In your case you have to change the last part of the classpath to customize your requirement.
Hope that will help.

Jaydeep

Unable to compile class for JSP. apache-tomcat-6. What could be wrong?

Hello, I am new to JSP and I am trying a very basic jsp and class file on Windows XP. I get the Unable to compile class for JSP.
Steps that I have done:
javac ch06_01.java , placed the ch06_01.class under
C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes
Then grabbed the ch06_02.jsp and placed it under
C:\Apps\apache-tomcat-6.0.16\webapps\ch06\
When I run it (by placing this into Explorer or Firefox URL
http://localhost:8080/ch06/ch06_02.jsp) I get the error further
below. Things I have done and made sure they are in place are:
set up JAVA_HOME to C:\Apps\jdk1.6.0_06
Using CATALINA_BASE: C:\Apps\apache-tomcat-6.0.16
Using CATALINA_HOME: C:\Apps\apache-tomcat-6.0.16
Using CATALINA_TMPDIR: C:\Apps\apache-tomcat-6.0.16\temp
Using JRE_HOME: C:\Apps\jre1.6.0_06
I did a google on the error and I found people saying to place the
tools.jar from the jsk into the lib directory under CATALINA_HOME. But
the examples still don't work. What step could I be missing? Your help is greatly
appreciated.
This is the simple jsp file:
<%@ page import="ch06_01" %>

I just updated the directories of the variables to reflect the current status of my system.

What is wrong is that you are using an "old" jsp tutorial :-)
Since Java 1.4, JSPs have been unable to access classes in the "default" package.
What you need to do:
Put the java class ch06_01 in a package.
Steps to do this
- Edit ch06_01 and add the following to the very top of the file (without the quotes): "package mypackage;"
- create a folder "mypackage"
- move ch06_01.java into that folder
- compile that class (now in the mypackage package)
- place ch06_01.class under C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes\mypackage
In your jsp:
<%@ page import="mypackage.ch06_01" %>
I would suggest using a more up-to-date tutorial that uses JSTL.
Take a look at this [Apache Tomcat tutorial|http://www.coreservlets.com/Apache-Tomcat-Tutorial/index.html]
