Weblogic 6.1 SP2 Caching Java Bean
Hi,
It seems like Weblogic 6.1 SP2 caches Java Bean, because any changes in Java Bean requires restart of the Instance. Is there any alternative to it , i am sure there will be..
waiting for reply .
Nope don't think so.
Any time you change the code of your javabeans, you need to redeploy them on the server - that normally requires a restart to pick up the changes.
Its the same with Tomcat and JRUN.

Hi
I'm new to the Java Beans concept. I'm going through the documentation for EJB on Sun website, but I feel that it's not complete. I'm searching for some tutorial that expalins how to use Beans in Servlets and JSP pages. Please post some useful links on how to use Java Beans in web applications. Also please suggest some useful books in Java Beans which I can use for reference.
Thanks.Thanks a lot for the information. But I have a doubt regarding hosting the Java Beans.
I'm using Apache Tomcat 5.0 for my Java Servlets and JSP pages. Can I use the same server to host Java Beans also ?. Or do I have to download the weblogic server separately to put Java Beans in it and then have Tomcat applications access the Beans from weblogic ?.
I can see the latter requires some process to be done, as I'm not familiar with weblogic server. Please advise me.
Thanks. -
Problems with a java bean in Weblogic 5.1
Hello,
I am having a problem deploying a java bean in Weblogic 5.1:
I have been given a .class and a .jar file for a java bean (not an EJB). I
placed the .class file into e:\temp\WEB-INF\classes and added the following
line to my weblogic.properties file:
weblogic.httpd.webApp.testApp=e:/temp/
I have also updated the web.xml file in the WEB-INF directory as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web
Application 1.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<servlet>
<servlet-name>EdIface</servlet-name>
<jsp-file>test.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>EdIface</servlet-name>
<url-pattern>EdIface</url-pattern>
</servlet-mapping>
</web-app>
When I try to access my http:\\server:port\testApp\test I get an "Error
500 - internal server error".
Has anyone had experice with deploying a java bean with jsut the .class and
.jar file? Where should I put the .jar file?
I appreciate any advice!

Can't deploy a SINGLE bean in weblogic 6.1 SP2 w/o application reload
Anyone know how to update a single bean in an application without
redeploying the entire application?
We have a project containing 101 beans (session and entity) and 372
jsps which we are deploying on weblogic 6.1, SP2 as a single
application. The project is deployed in an exploded directory format
as follows:
trader/
META-INF/application.xml
lib/
third-party.jar
third-party.jar (etc.)
SessionBean.jar
EntityBean.jar (etc.)
trader/
WEB-INF/web.xml
META-INF/MANIFEST.MF (contains Class-Path: entry to lib dir)
jsp/html/gif's reside below this point.
Each bean jar has a META-INF/MANIFEST.MF to resolve third-party
library dependencies through the use of the Class-Path entry.
When we we try to update a single bean's implementation, the
entire application reloads, which can take between 10 - 30 minutes.
We have tried using the weblogic.deploy tool as well as undeploying
and redeploying the bean from the console. In both cases, the
entire application reloads.
When we use weblogic.deploy, we've tried the following:
weblogic.deploy
-url T3://localhost:7001
update weblogicpwd trader ~/trader/build/SessionBean.jar
and
weblogic.deploy
-url T3://localhost:7001
-component SessionBean:srvr1

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Hi, I have quick question about use of USEBEAN tag in SP2. When I
specify a scope of SESSION for the java bean, it does not keep the
values that I set for variable in the bean persistent.Thanks,Sonny

Unable to invoke WebLogic 8.1 sp2 web service from a java proxy client...
I am not able to invoke a web service deployed on WebLogic 8.1 SP2 via a client using the proxy jar provided by WebLogic's JWS > Overview > Generate Java Proxy tool.
I am getting a java.net.ConnectException.
Both the client and the WebService are on the same server.

DESCRIPTION:
When a platform domain is created, the admin server can be started without
any issues and a managed server can also be started without any errors if
using startManagedWebLogic.sh. But when a managed server is started using the
nodemanager, the managed server fails to start with the following error.
The WebLogic Server did not start up properly.
java.lang.NoClassDefFoundError: com/bea/wsrp/util/debug/Debug
(Complete stack trace with be added as a note)
The reason for this is that:
startWebLogic.sh(cmd) and startManagedWebLogic.sh(cmd) for platform domains
call <User domain>/setDomainEnv.sh which includes all the jars necessary for
a platform domain in the CLASSPATH.
Whereas startNodeManager.sh calls <WL_HOME>/common/bin/commEnv.sh, which is
the same for both platform and server installations of weblogic and has only
weblogic.jar in the CLASSPATH.
Looking at historical cases, the steps to start NodeManager successfully in a
platform domain are:
1.
a. Copy admin server classpath (from <user Domain>/startWebLogic.sh) to
that of all managed servers in the 'Remote Start' tab of the WLS Console
OR
b. Copy admin server classpath to <WL_HOME>/server/bin/startNodeManager.sh
(If the same nodemanager is used to manage server domain servers and platform
domain servers, will there be any issue with this approach??)
2. Copy the wsrpKeystore.jks file from your domain directory to the
nodemanager directory (the parent of the directory where all the server
directories are replicated in the node manager. By default: <WL
HOME>/common/nodemanager)
But these steps are not publicly documented in edocs.
CONFIGURATION:
Weblogic Platform Domain 8.1 (all service packs)
WORKAROUND:
Steps 1 and 2 above. -
CAN I DO DATA CACHING by JAVA BEAN persistence?
I need to keep Objects cached in the server side. so in order to make it persistence can i use JAVA BEANS.
I am not interested to do for EJB.
I need a cache component build in the server side .
how can i do it in JAVA / J2EE platform?Your cache doesn't necessarily need to be persistant unless you're doing something like calculating the size or keeping it between server restarts.
A simple cache is very easy to do but can get quite complex very quickly. Search for Caching on javaworld.com there's a pretty good article on it there.
Also take a look for JCache on jcp.org, it's a request for a cacheing spec to be built into Java. Some interesting stuff there.
Basically all you need is a HashMap to hold, keys and objects. -

Java.lang.OutOfMemory error when transforming xml using xsl with Weblogic 6.1 sp2
Hello,
I have an OutOfMemoryError when applying an xsl transformation to generate html
code in a web page. I'm running Weblogic 6.1 sp2
I think the problem comes from the objectin which th html is stored during the
transformation. The problem only occurs from a minimal xml size. I could fix
it by increasing JVM allocated size but I would like to find a more flexible solution.
If I know an other way to solve this problem, I really would appreciate !
Thanl you,
Laurent.
[AgentsGeres.jsp]Hello,
You might try asking your question in the JSP newsgroup:
http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=xover&group=weblogic.developer.interest.jsp
There just may not be a more flexible solution :-)
This doc may be of some value, see chapter 2:

Using JSTL on Weblogic 8.1 SP2
I'm trying to create a web app running on Weblogic 8.1 SP2 that uses JSTL tags.
I've downloaded the Apache 1.0.5 Reference Implementation of the JSTL 1.0 spec,
but I can't get the sample web-app (standard-examples.war) to work correctly.
When I go to the "General Purpose Tag Examples" and try to view the Out example
JSP, I get a large exception saying that java.lang.NoClassDefFoundError: javax/servlet/jsp/el/ELException
(full stack trace at bottom). This also happens when I try to view the JSP source
and pretty much any other example. I found that the German example in "I18N &
Formatting" works, but running the Italian example gives a new exception:
Parsing of JSP File '/format/ItalianLocale.jsp' failed:
/format/ItalianLocale.jsp(12): for tag 'message', property 'bundle' of tag handler
class 'org.apache.taglibs.standard.tag.rt.fmt.MessageTag', the value must be a
runtime expression "<%=...%>", since we cannot do an automatic conversion from
"${itBundle}" to type 'javax.servlet.jsp.jstl.fmt.LocalizationContext' and there
is no custom property editor for that type
probably occurred due to an error in /format/ItalianLocale.jsp line 12:
<fmt:message key="greetingMorning" bundle="${itBundle}"/>
I can, however, get this to work on Tomcat 5.0. Has any else had this problem?
Is there something that I'm doing incorrectly?
Thanks in advance.

Weblogic 6.0 sp2: War deployment not working !!
Hi,
I'm using weblogic 6.0 sp2, and it seems as though the war deployment is not
working. My war consists of jsps, images, and under the WEB-INF/classes
directory, Struts classes (i.e. Form and Action classes). When I try to run
a jsp, i get the following error :
<Jul 30, 2001 11:48:10 AM PDT> <Error> <HTTP>
<[WebAppServletContext(4655498,ati
nera)] Root cause of ServletException
javax.servlet.jsp.JspException: Exception creating bean of class
com.atinera.log
in.web.LoginForm: java.lang.ClassNotFoundException:
com.atinera.login.web.LoginF
orm
But if you look in the war, that class is in there.
What gives ?
Thanks,
JamieThat's right - ActionServlet does Class.forName(actionClass) to load action
class, and this uses ClassLoader which loaded the current class (ActionServlet)
ClassLoaders always delegate to their parent before attempting to load
the class themselves, so it wasn't working until you moved struts.jar to your
WEB-INF/lib.
BTW, Struts doc mentions this problem:
lib/struts.jar - This JAR file contains all of the Java classes included
in Struts. It should be copied into the WEB-INF/lib directory of your web
application. WARNING - If you are going to be hosting multiple Struts based
applications on the same servlet container, you will be tempted to place the
struts.jar file into the shared repository supported by your container. Be
advised that this will like cause you to encounter ClassNotFoundException
problems unless all of your application classes are stored in the shared
repository.
Jamie Tsao <[email protected]> wrote:
So I found the solution to this problem, but it doesn't really make sense to
me.
I originally had struts.jar outside of the WAR file, but in my CLASSPATH.
Weblogic was able to load Strut's ActionServlet (controller), but when the
ActionServlet was looking for the LoginForm (which was inside the WAR), it
couldn't find it.
I solved the problem by putting struts.jar inside the WAR (under
WEB-INF/lib) instead that other directory. Now it works cause apparently
ActionServlet is now in the same classloader as LoginForm, the classloader
which loaded the WAR.
I'm confused because original way should have worked since the classloader
that loaded struts.jar from outside the war is the parent classloader for
the classloader that loaded the WAR. did that make any sense ?
anyone know why ?
thanks,
jamie

Weblogic 6.1 SP2 hangs up at database command, PATCH needed!
Hello,
I use weblogic 6.1 SP2 on Windows and Solaris
DB-Driver: Oracle Thin Driver for Oracle 9i
Database OP System: Win2000
My application runs fine. After some time (about 15.000 db operations)
at load tests, the weblogic 6.1 server hangs up without an error message
in the logs at a any desired database command.
I use the database pool from weblogic.
The database operations are made with the TX-Datasource.
The main database operation is a call of an oracle stored
procedure.
I suppose, that the weblogic hangs up in a synchronized
block of the pool, but the crash could also have an other reason.
After the crash, the whole instance is dead and must be restarted.
I can reconstruct the crash on windows and solaris.
I always thought, weblogic is reliably?
Is there any patch to fix this problem?
I am very thankful for every help to fix this problem.
Thank you in advance
MarkusHi,
here is the source code of the the stateless session bean (S1), which
calles the oracle stored procedure.The commit or rollback is done in
the main interface (stateless session bean with user managed
transactions).
java.sql.CallableStatement stmt=null;
java.sql.Connection conn = null;
try {
javax.sql.DataSource ds =
at.one.bmw.system.SystemConfig.getDataSource();
conn=ds.getConnection();
stmt=conn.prepareCall("{call routeChargingRecord(?,?,?,?,?,
int i=1;
stmt.setString(i++,seq_number);
stmt.setInt(i++,custTypeID.intValue());
stmt.setString(i++,msisdn.toString());

try { stmt.close(); } catch (Exception en) {}
try { conn.close(); } catch (Exception eb) {}
conn=null; stmt=null;
} // end try
catch (Exception e) {
this.sessionContext.setRollbackOnly();
try { stmt.close(); } catch (Exception en) {}
try { conn.close(); } catch (Exception eb) {}
throw new EJBAppException(msg+"\n"+e.getMessage());
} // end catch

WebLogic 6.1 SP2 stateful EJB handle serialization problem
I try to serialize and later deserialize the handle of a stateful
session bean in WebLogic 6.1 SP2. This works on the client, but not on
the server. In WebLogic 6.1 SP1, it worked on both server and client.
The test code:
try {
InitialContext context = new InitialContext();
InfSessionHome sessionHome = (InfSessionHome)
InfEJBUtil.getInfEJBHome
(context, InfJNDINames.INFSESSION_EJBHOME,
InfSessionHome.class);
infSession1 = sessionHome.create();
// serialize
ObjectOutputStream objector = new ObjectOutputStream(byteStream);
objector.writeObject(infSession1.getHandle());
objector.flush();
objector.close();
byte[] ejbKeyBytes = byteStream.toByteArray();
// deserialize
ByteArrayInputStream byteInStream = new
ByteArrayInputStream(ejbKeyBytes);
ObjectInputStream objStream = new ObjectInputStream(byteInStream);
Handle ejbHandle = (Handle) objStream.readObject();
objStream.close();
InfSession infSession2 = (InfSession) ejbHandle.getEJBObject();
if (!infSession2.equals(infSession1)) {
throw new IllegalStateException("not equal: " + infSession2);
} catch (Exception e) {
e.printStackTrace();
I get the following stack trace in the readObject() call:
java.io.InvalidClassException:

at java.io.ObjectInputStream.readObject(ObjectInputStream.java:236)
I suppose that WebLogic uses a different handle on the server
(LocalServerRef class, handle local to it's EJB) than on the client.
I took the routine from Apache SOAP 2.2 StatefulEJBProvider. So I
suppose that more people are running into the same problem.
Does anybody know of a workaround?
TomJust a small addition/clarification to what Cameron said on serialization.
- The no argument constructor is required in the first non-serializable class in the object hierarchy for de-serialization process. If your class extends form Object class(which has a no arg constructor), you need not have a no-arg constructor. refere to http://64.49.216.133/faq/view.jsp?EID=251942 for more details.
- Also I suggest using the api
isIdentical(...)
instead of equals method in the code if you are trying to establish whether the two objects represent the same EJBObject or not
- Rajeev
Cameron Purdy <[email protected]> wrote in message news:[email protected]...
A no-argument constructor is required for a class to be deserialized. It
sounds like a BEA bug from the stack trace, but make sure you don't have
something extra that you are serializing on something of yours that should
be transient. (It's hard to imagine how, but you never know ...)
Peace,
