BEA Responses to Newsgroup
Does BEA staff look at this newsgroup at all? If not how can I get my
question answered:
"Any information on the purpose of the GC threshold setting? There seems to
be universal agreement that setting the GC threshold is at best pointless.
Looking for any clarification on this issue.
TIA"
I am curious to know as much about BEA specific issues (very familiar with
how the GC works so not looking for boiler plate information) regarding
memory since it seems to be extremely unreliable versus other platforms.
Anybody have any helpful hints in that regard?
TIA, again
I don't quite understand. Do you want to view the responses in more of a record view? Go to the View Responses tab, select the View menu and click Detail View. Is this what you are looking for?

Installing another WLS 6.0 instance in same root /bea directory
I have a running WLS 6x instance in /bea/wls6***. I want to put another
instance in /bea directory as a totally separate instance (/bea/wls6trn
e.g.) Is this a valid way to do this or do I need to go ahead and install to
another separate filesystem.
darylDaryl,
What is it you are trying to accomplish? You do not need to install the software
multiple times to have multiple instances running on the same machine. In fact, I
always recommend to our customers that they never use the BEA-HOME directory
structure to store ther application-specific data. If all you want to do is create
two separate domains on the same machine, do the following:
1.) Install the WebLogic Server 6.1 (or 6.0) software (it will go under
$BEA_HOME/wlserver6.1).
2.) Create some other directory somewhere outside of the $BEA_HOME directory
structure (e.g., /usr/myApp1).
3.) Copy the $BEA_HOME/wlserver6.1/config directory to /usr/myApp1 (you can delete
the examples and PetStore directories under /usr/myApp1/config directory).
4.) Edit the /usr/myApp1/config/mydomain/startWebLogic.sh script to reflect the
fact that the WebLogic software is installed elsewhere.
5.) Repeat steps 2 through 4 as many times as you want to create as many instances
as you want...
Hope this helps,
Robert

Hi Daryl
That is a weblogic 6.x design constraint. Weblogic 6.x keeps the history of
versions under BEA-HOME, in the registry.xml file. So, if you have already
installed same weblogic version with same service pack level then the installer
won't allow you to install it second time. You should have different bea-homes.
I hope this clarifies your query.
Thanks & Regards

Hi Daryl
Greetings...!
How are you doing?.
You can have different versions under same BEA-HOME. For example
BEA-HOME is /bea
----/wlserver6.1(weblogic6.1 build)
----/wlserver6.1sp1 (weblogic 6.1 with sp1build)
----/wlserver6.0sp2 (weblogic6.0 with sp2 build)
But you can't have more than one wls instance of same version under one
BEA-HOME. You have to choose different BEA-HOME, /beatrans

Ejb security role & bea implementation
A role has been defined in ejb-jar as following:
<security-role>
<description><![CDATA[Deployer User]]></description>
<role-name>deployer</role-name>
</security-role>
<method-permission>
<description><![CDATA[Deployer Method Permission]]></description>
<role-name>deployer</role-name>
<method>
<description><![CDATA[All method for CCPStateBean]]></description>
<ejb-name>CCPStateBean</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>
If the principal is included in the weblogic-ejb-jar as below, and the jndi lookup
includes the SECURITY_PRINCIPAL (e.g., jzhu), the code works fine.
<security-role-assignment>
<role-name>deployer</role-name>
<principal-name>jzhu</principal-name>
</security-role-assignment>
The problem comes when the principal is not included as above weblogic-ejb-jar
instead a role "deployer" is defined in WLS's, The user ("jzhu") is defined in
the deployer group. And the deployer group belongs to deployer role. The defaultRoleMapper
is enabled. In this scenario, the access failed due to insufficient permission.
Can ejb-jar's role relates to WLS's role. Please advise. THX.

Has anyone tried using Apache's Cocoon for managing web publishing? I've
has a go with Xalan and Xerces, and been pleased with these to date. I've
now come across Apache's Cocoon, and would be interested to here the
opinions of anyone who has used it already.
Mark.I also managed to get cocoon and weblogic 451 working without too much
difficulty.
However I have't been able to suss out the mechanism for passing a default
file to the cocoon servlet.
Anybody know what to do?
Humphrey Sheil <[email protected]> wrote in message
news:[email protected]...
I got Cocoon 1.7.4 working with weblogic 5.1 very easily (apart from one
major issue which I'll detail and gripe about below ;-)).
I used the instructions posted on the Cocoon list by Philip Aston (which
I've included below) which worked but one change was required.
I got a problem (about 50% of the time) where weblogic would fail todeploy
my cocoon war and also complain about another process listening on ports
7001 / 7002 which simply wasn't true. Turns out that if weblogic isunable
to parse the web.xml that comes with cocoon, I had to replace it with an
example taken from the weblogic examples directory (with the relevant
information included). The way weblogic deals with this - cascading the
error in deploying to affect the port listening is not good.
Once I got this working, I hooked up security etc. in about 10 minutesusing
the servlet 2.2 form-based authentication and am generally very happy with
the weblogic-cocoon integration.
Here are the posted instructions and I'm also attaching my web.xml file asa
reference. I didn't have any problems getting XSP to work (although I'mnot
using it at all - just hitting the samples provided). Even given thepoints
Philip makes below about losing hot deploy abilities, your EJBs should
deploy fine with this turned off.
Regards,
Humphrey

I've been playing with using Cocoon 1.7.4 in conjunction with BEA
WebLogic Server 5.1. (Stefano and folks, feel free to add any or all
of this to the installation guide. You might also like to add a
success report for MS NT 4.0 SP4, BEA WebLogic Server 5.1 SP3, JDK
1.2.2.)
WLS 5.1 implements Servlet 2.2. so it plugs in easily. Here's a quick
recipe:
- Add the xerces, xalan, fop, servlet, and cocoon JAR files (from the
distribution) to your CLASSPATH. (See below). If you're using Java
2, you should also add the tools.jar file from the JDK distribution
to your CLASSPATH.
- Create a new subdirectory tree of your WLS run time directory
"cocoonwar/WEB-INF" and copy the default web.xml file (from the
src directory of the distribution) there.
- Copy the cocoon.properties from the conf directory of the
distribution to cocoonwar/WEB-INF and updated the web.xml file to
refer to it.
- Copy the samples directory from the distribution to cocoonwar
- Map the web application into the WLS URI name space by adding the
following line to your weblogic.properties file:
weblogic.httpd.webApp.cocoon=cocoonwar
Start WLS, point your browser at
"http://localhost:7001/cocoon/samples/index.xml" and away you go.
Classpaths and XSP:
To support hot deployment of EJB's and Servlets, WebLogic Server
uses its own class loader with its own classpath (the "WebLogic
classpath"). Normally you'd put all the WebLogic Server container
code, JDBC drivers, etc. in your Java CLASSPATH (so that WebLogic
Server can start up) and add all your application code (stuff that
needs to be able to be redeployable) to the WebLogic classpath.
Cocoon is effectively "container" code, and the XSP processor uses
dynamic classloading which only understands the Java CLASSPATH, so
you should put all of the Cocoon jars in CLASSPATH.
The big problem with this is that you can't use any code that loads
from the WebLogic classpath within XSP's. This includes all of the
WebLogic API, so is a PITA. To overcome this, either the way Cocoon
loads classes needs to be modified (Stefano, is this easy?), or the
WebLogic Server class loader needs to be disabled (in which case you
have to be willing to live without hot redeployment).
To disable the WebLogic class loader, put your application classes,
the Cocoon jars and all of the WebLogic Server stuff into the Java
CLASSPATH add -Dweblogic.system.disableWeblogicClassPath=true to the
Java command at the end of you WebLogic start script.

you need to do is usethe -Dweblogic.system.disableWeblogicClassPath=true

that some of my EJBs won't deploy.
If you don't want XSP Cocoon works well.

Weblogic apache plugin and webservices
Can I use the weblogic plugin on a DMZ based Apache server and use a 3 tier architecture
to implement webservices.
Using this model can a external application contact my webservices running in
my internal network and can my weblogic/webservices server contact an external
application/webservices using the same route i.e through the apache webserver
and weblogic plugin.
Any documentation regarding the architecture?Hi Anil,
Not sure this is possible, unless you are using it as a proxy and setup
the proper host/port mappings, see:
http://edocs.bea.com/wls/docs81/webserv/client.html#1072224
We have a very responsive security newsgroup, you might ask your
configuration question there:

Strange Cluster Startup Timing Issues (Solaris 2.7)
When we start up our admin server for our WLS 6.0sp1 cluster (running on Solaris
2.7), then try to start all the managed servers approximately simultaneously,
the managed servers come up apparently normally (no errors in the logs) but no
EJBs ever deploy.
If we follow the same steps, but wait until each server is all the way up before
starting the next, everything is fine.
Has anyone else run into this?
-daniel
Hmm, I wonder if they "cannot" or "will not" supply you the patch...
Oh well, hopefully this won't get me in trouble! Here's the patch, stick it in your weblogic /lib
directory or in CLASSPATH, and add the following to your startup command:
-Dweblogic.rmi.queuesize=n
And if you are having problems, don't tell BEA who gave this to you! :-)

Hi all ,
I create a simple stateless ejb named LoginSession to manage the login task
, package it to a ejb jar file named login.jar , and then I want to explode
it as a wls7.0 webservice , the build.xml like this :
<project name="buildWebservice" default="ear">
<target name="ear">
<servicegen destEar="login.ear" contextURI="login">
<service ejbJar="login.jar" includeEJBs="LoginSession"
targetNamespace="http://www.ricobest.com/webservice/login"
serviceName="LoginSession" serviceURI="/LoginSession" generateTypes="True"
expandMethods="True"/>
</servicegen>
</target>
</project>
When after ant running successfully , ant generated login.ear file for me ,
but I find some ploblems :
1 , the ear file contains login jar and web-service.war file , similar with
wls6.1 webservice , but the web.xml file in web-service.war is different
from wls6.1 , the 7.0 file is black ! only the following 3 lines :
#1 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
#2 <web-app>
#3 </web-app>
2 , I can not file the wsdl.jsp file in the ear file , whick will contained
in 6.1 webservice .
3 , when I want to request http://localhost:7001/login/ , error message
list in my browser :

Hi all ,
I create a simple stateless ejb named LoginSession to manage the login task
, package it to a ejb jar file named login.jar , and then I want to explode
it as a wls7.0 webservice , the build.xml like this :
<project name="buildWebservice" default="ear">
<target name="ear">
<servicegen destEar="login.ear" contextURI="login">
<service ejbJar="login.jar" includeEJBs="LoginSession"
targetNamespace="http://www.ricobest.com/webservice/login"
serviceName="LoginSession" serviceURI="/LoginSession" generateTypes="True"
expandMethods="True"/>
</servicegen>
</target>
</project>
When after ant running successfully , ant generated login.ear file for me ,
but I find some ploblems :
1 , the ear file contains login jar and web-service.war file , similar with
wls6.1 webservice , but the web.xml file in web-service.war is different
from wls6.1 , the 7.0 file is black ! only the following 3 lines :
#1 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
#2 <web-app>
#3 </web-app>
In WLS 7.0 there is a new DD file for Web Service. Look for
web-services.xml file inside the WEB-INF dir. There is no
change needed to the web.xml file.
2 , I can not file the wsdl.jsp file in the ear file , whick will contained
in 6.1 webservice .
The WSDL is generated from the deployment information at
runtime.
3 , when I want to request http://localhost:7001/login/ , error message
list in my browser :
Error 403--Forbidden

I think the URL you need to hit is:
http://localhost:7001/login/LoginSession

You can use clientgen to generate the client.jar file
by pointing to the deployed WSDL.

Foreign JMS Providers with WebLogic Server does not close connection
Hello All,
We tried to use wlsmqseries.zip classes (specially JNDI Mapper) for integrating
WebLogic Server with MQ so that we can incorporate XA transactions. We use LDAP
context factory to bind MQ.
We found a number of LDAP connections are getting opened by JNDIMapper, but it's
not getting closed.
Can some one give some clue to this ?
Also any suggestion to serve the current purpose is welcome.
Thanks,
Sudarson
What version are you using? "wlsmqseries.zip" does enlisting of MQ JMS
sessions in XA transactions, but WLS 8.1 does that for you out of the box.
If you're using 8.1, it would be better to use the new 8.1 features for
foreign JMS providers.
A place to start is the "Using WebLogic JMS with EJBs and Servlets" section
of the JMS programming documentation for 8.1, and there have been many other
posts on this newsgroup with details. (There also appear to be quite a few
customers using this feature in their own systems, judging from the number
of posts.)

[Fwd: Client accessing MBeanHome for more than one domain receives SecurityException]
Fwd'ing to security newsgroup
-------- Original Message --------
Subject: Client accessing MBeanHome for more than one domain receives
SecurityException

Newsgroups: weblogic.developer.interest.management
Hi,
When a client accesses MBeans of more than one domains (Weblogic 8.1)
that have
different passwords, it receives a SecurityException. This occurs when
the MBeanHome
for each domain is looked up at initialization and reused for each
request ( to
access MBeans ). The security exception does not occur if the MBeanHome
for each
domain is looked up for each request. On initial review, this behavoir
seems inconsistent.
Looking up the MBeanHome for each request may introduce a significant
overhead.
I am not sure if concurrent lookups would also cause the same problem.
I have read on another post that we can work around this problem by
establishing
a trust relationship between the servers, but this may not be feasible
when one
is monitoring a lot of servers and the overhead of configuration may be
an issue.
I have attached code that can reproduce the problem.
Please advise on the correct approach.
Thanks

* Note: the exception is caused only when the MBeanHome for each domain is cached and used for subsequent

* would significant overhead in practice. Also the transactions across the various domains occurs serially, hence
* the effect of concurrent lookups has to be tested.
* Usage:
* This class has been tested with weblogic 8.1
* The class needs weblogic.jar in its classpath
* One can specify the weblogic details as System properties. The properties need to be specified in
* the following format:
* wls.host.n, wls.userId.n, wls.password.n where n is the weblogix instance number. Also specify
* the boolean system property reconnect.each.iteration to toggle between reconnecting or not reconnecting
* for each iteration. When not reconnecting for each iteration, the MBeanHome is reused and the Security Exception
* occurs.
* Following is the example of system properties
* -Dwls.host.0=localhost:7001 -Dwls.userId.0=weblogic -Dwls.password.0=weblogic
* -Dwls.host.1=localhost:7011 -Dwls.userId.1=weblogic -Dwls.password.1=weblogic1

Possible Bug? autotype + wsdl2service generates implementation that does not conform to the WSDL
Hey folks,
I've got some hand crafted, valid, WS-I compliant WSDL + imported XSD that I've
been using for awhile now to generate an Apache Axis 1.2 beta Document Literal
Web Service implementation. I'm now trying to use the same WSDL to generate a
BEA WL 8.1 SP2 Document Literal Web Service implementation and I'm running into
problems.
I've attached the WSDL, XSD, and build script that I'm using to generate the implementation.
It deploys fine, but notice that the autogenerated WSDL that is returned from
the deployed BEA Web Service contains two <xs:schema> sections: one for the imported
WSDL (as expected) and one for several new elements that seem to get substituted
for the elements used in the orignal WSDL message parts.
The results of this are two fold:
1) the autogenerated WSDL appears to be invalid when loaded into both XMLSpy and
SOAPscope
2) the SOAP requests to invoke the operations on the service do not conform to
the hand crafted original WSDL. I've attached examples of both a BEA generated
SOAP request and an EXPECTED SOAP request.
I've poured over both the types.xml and the web-services.xml, and I'll be damned
if I can see the problem. I'm wondering if the way I import schemas and reference
elements declared therein is somehow not supported by BEA's ant tasks?
Any advice or pointers at all would be appreciated.
Regards,

[BankService2.zip]I don't know if you already now this but if you are using <autotype> to generate
the types.xml from the XML Schema then you should first
1) autotype the imported schema first.
2) Then for the actual achema (that uses the imported xsd) <autotype> but with
the
typeMappingFile="importedSchemas/types.xml"
option set to the types.xml output from 1)
The types.xml will then contain all types from both Schemas. You can then pass
this final types.xml from 2) to <source2wsdd> via
typesInfo="types.xml"
Any help ?

Setting Isolation Level In A UserTransaction
We are having a problem where a class creates a UserTransaction from the InitialContext,
but does not see any database changes made by other EJBs even though they have
been committed. This "seems" like an isolation issue.
What is the default isolation level for UserTransaction? And since it appears
that it is not seeing committed data, what level should it be set to? (i.e. TRANSACTION_READ_COMMITTED
would be nice...)this is mirrored from the transaction newsgroup:
Joseph Weinstein <[email protected]> wrote:
>

Interesting, but it's not an isolation level issue. There is no DBMS
isolation level
that could cause a user not to see already-committed data.Well, we are using Oracle as our backend and it supports Read Uncommitted, Read
Committed and Serializable. The Serializable option would prevent a transaction
from seeing any committed data to a table (i.e. prevents unrepeatable reads).
The default isolation level of most DBMSes is READ_COMMITTED, and you
should
never have to change it, and you should be able to see already-committed
data.I agree, but that is not happening for us (and this gets somewhat complicated
with JMS). What is Weblogic 8.1's default isolation level for any transaction.
From the link below, I get the impression it is SERIALIZABLE which would explain
the behaviour I'm seeing. Athough the article seems to be talking about CMT (container
transation), I would suspect a BMT (bean managed transaction) be similar (just
manual).
If this only confuses things, please let me know the easiest way to communicate
this issue (code, etc..)

[Fwd: Re: rdbms realm and connection pool]
Hi,
One reason why I would like to use the connection pool for the RDBMS
realm is because there is the retry machanism built into the connection
pool. With this retry, I don't need to re-start WebLogic if the DB
server is somehow re-started. With the current implementation, all the
connections maintained by the realm will become invalid if the DB server
has been restarted independently.

I believe not- the realm restricts access to connection pools to those
who
are allowed it, so if the realm needs the connection pool to start up,
and
you can't open the connection pool without the realm then you have a bit
of
a no-chicken and no-egg situation, which is I believe one of the reasons
why
there is no use of connection pools, ejbs, jndi, servlets etc. in the
realm
(along with other reasons, like why would it be provided with a servlet)
The delegate pool acts somewhat similarly to a connection pool, and can
even
use the same database, so I'm not sure what the advantage would be

Sams Teach Yourself Javaserver Pages in 24 Hours
Hi.
I'm a new user of Weblogic and I'm presently learning JSP. Like most people do
I went out and bought a beginner's book on JSP.
The book I bought is Sams Teach Yourself Javaserver Pages in 24 Hours by Jose
Annunziato (DSc) and Stephanie Fesler Kaminaris.
Up to now I've spent the 5 first hours trying to run my first JSP on Weblogic
(seems like it's going to take more than 24 hours to complete the book!). The
problem was simply a wrong path for the compileCommand variable in the weblogic.properties
file.
the authors suggest the following:
compileCommand=c:/jdk1.2.2/javac.exe
when it should be:
compileCommand=c:/jdk1.2.2/bin/javac.exe
The point I want to make is that this type of error is far too frequent in computer
programming books, considering the prohibitive price they're sold at, and it shows
a lack of respect on the part of the authors and/or publishers for the people
who buy them. I encourage everyone to do like me and denounce these people on
newsgroups all over the Internet. When their sales go down they will surely take
action.
On the positive side, I want to congratulate BEA for their newsgroups. This is
how I finally got on the track to solving my problem. Otherwise, I probably would
have spent at least 24 hours hacking around just to get that first JSP to work
in Weblogic.

compileCommand=c:/jdk1.2.2/bin/javac.exe
The point I want to make is that this type of error is far too frequent in computer
programming books, considering the prohibitive price they're sold at, and it shows
a lack of respect on the part of the authors and/or publishers for the people
who buy them. I encourage everyone to do like me and denounce these people on
newsgroups all over the Internet. When their sales go down they will surely take
action.
On the positive side, I want to congratulate BEA for their newsgroups. This is
how I finally got on the track to solving my problem. Otherwise, I probably would
have spent at least 24 hours hacking around just to get that first JSP to work
in Weblogic.
Thanks.
