Problem in synching multiple web applications
I have a domain called myDomain. In this domain I have 2 enterprise applications
say
ent1App with ent1App-project and ent2App with its ent2App-project. Each enterpsrise
application has one web application
(webApp1 and webApp2 respectively). I have the same set of webflow files (.wf
files) in both
ent1App-project/application-sync/web-apps/webApp1 and ent2App-project/application-sync/web-apps/webApp2
directories.
Now suppose I synchronize my webflows (using EBCC) for say ent1App. The synchronization
is accomplished without any problems
and this is confirmed when the entries get updated in the Master Data Repository
where all the webflows for ent1App get
stored. This is as viewd using the datasyncservlet.
If I now do a synchronization on the other enterprise application called ent2App,
the synchronization takes place
successfully but when viewed in the datasyncservlet, it shows up the entries for
the webflows of ent2App. i.e. the entries
for all the weblows of ent1App which were shown in the Master Data repository
are not shown.
We looked up the Cloudscape database to ensure that the entries for both the enterprise
applications are present and it does
contain the records for both the applications. This however does not show up in
the datasync servlet. Due to this we get a
namespace not found error whenever we try to access the application whose entries
are missing in the master data repository.
I have separate names for my datasync folder for each of the applications in my
config.xml as shown below
ent1App
<Application Deployed="true" Name="ent1App"
Path=".\config\myDomain\applications\ent1App" StagedTargets="iden_staging">
<WebAppComponent DeploymentOrder="1002" Name="datasync" Targets="iden_staging"
URI="datasync"/>
ent2App
<Application Deployed="true" Name="ent2App"
Path=".\config\myDomain\applications\ent2App" StagedTargets="iden_staging">
<WebAppComponent DeploymentOrder="1002" Name="datasyncDev"
Targets="iden_staging" URI="datasyncDev"/>
I am using WLS6.1 SP4 and WLP 4.0 SP3
Can someone please tell me what could be the problem?
Thanks

When you peform a data sync you are updating the data_sync_item table
with the EBCC xml files. For those files that are not present in the
EBCC project they will be deleted from the table.
You can not use multiple enterprise applications that contain Portals.
Try using using multiple domains that contain separate databases for
datasyncs.
Here is a snippet I recently sent out in a support case:
Unfortunately there is not a documented best practice for maintaining
multiple projects and enterprise applications. In my opinion if you
plan to create multiple enterprise applications they will need to
maintain separate application components and web applications. The
enterprise applications will need to use the same portal resources
(pools) and therefore same tables. The synchronization modes documented
at http://e-docs.bea.com/wlp/docs40/deploygd/appdata.htm explain the
limitations in data sync -- either all files are deleted and updated or
only modified files are updated. Either mode will delete files from the
data_sync_item table that do not exist in the current project.
Therefore one project will need to be used per domain.

Multiple Web Applications WLS 7.0
Hi,
I am trying to configure multiple web applications on the same WL 7.0 server and
am having trouble doing the following.
I would like to be able to use the following URLS:
Application #1:
http://myserver/st/aems - where st/aems maps to the path X:\SimpleTrade2\AEMS\ui\source\htdocs
Application #2:
http://myserver/st/acms - where st/aems maps to the path X:\SimpleTrade2\ACMS\ui\source\htdocs
Root - Default web application - This would be left empty with the idea that our
company could sell our web applications and we would deploy them on someone elses
WLS and we would not conflict in any way.
The problem with the above is that when I look at the DTD and try and configure
config.xml in the following way:
<Application Deployed="true" Name="AEMS"
Path="X:\SimpleTrade2\AEMS\ui\source\htdocs" TwoPhase="true">
<WebAppComponent DeploymentOrder="2000" Name="aems"
Targets="simpletradeserver" URI="st/aems"/>
WLS blows up on startup because it tries to POST-Pend the URI to the path... If
I change it to:
<Application Deployed="true" Name="AEMS"
Path="X:\SimpleTrade2\AEMS\ui\source" TwoPhase="true">
<WebAppComponent DeploymentOrder="2000" Name="aems"
Targets="simpletradeserver" URI="htdocs"/>
This will work but then my URL is not what I want it becomes http://myserver/htdocs
Is there anyway around this or a way to get what I want?
Another piece of information, I am developing in Exploded directory format when
we deploy it will be as an ear.
Thanks in advance for any ideas!!!
-Jerry RodgersThanks for the info Christian.
I thought I would pass along a bit more inforation for others who might be trying
to do something similar. In case they run across this message.
I did determine that if you are using a .WAR file the name attribute of the xml
node WebAppComponent will allow you to create a different context path than the
URI. I did not test to see if it allowed you to use a name like "st/aems" I am
sure "st.aems" would work or any name that may be different than the URI. The
weird thinhg is that when using the EXPLODED DIRECTORY format the URI is the name
of the folder under the path and the name property appears to be ignored no matter
what you change it to you can only get to your web app using the URI.
Hope this helps someone who comes after me and is looking for the same thing,
maybe they won't spend 6 hours on it like I did ;>

Hi,
this is not possible.
The URI field contains the directory name of the WebApplication, which
normally
is the same name as the directory where you put the webapplication in.

Authentication Across Multiple Web Applications (Revisited)
Its been an ongoing battle, but I've made some insight into this situation. The problem stands as it seems impossible to authenticate against one web application deployed as a WAR archive and have that authentication carry across to another web application with the same security constraints. I've been told by BEA that, quote:
"It seems to me that we are violating section 11.6 of the servlet 2.2 spec which talks about webapps"
I've also been told that this is fixed in WLS 6.0, reference issue #38732.
For those of us building production environments using 5.1 instead of 6.0 XML based configuration, this does NOT solve our problem.
I've dug further into the bowels of 5.1 and found that if you manually set the realm name in the login-config of the security constraint in the web.xml file in each WAR deployment as such:
<login-config>
<auth-method> [whichever method] </auth-method>
<realm-name>WebLogic Server</realm-name>
</login-config>
Authentication will carry across web applications. However, I've noted that the session management then becomes unpredictable. For example:
I log into the application TESTAPP1 which contains a protected servlet that outputs the session ID and attempts to get the authenticated principal name from the "_wl_authuser_" session variable. Upon first load of the page (after the login dialog box), the session is null [can be fixed with .getSession(true) call instead] and the "_wl_authuser_" object does not exist. Reload the page and the session appears as well as the "_wl_authuser_" object. Strange.
I then move to TESTAPP2, which does not prompt me for authentication but also is missing the session in the same manner. Upon browser reload, the session is created with a different ID and the "_wl_authuser_" object is now available with the appropriate principal name.
Upon moving back to TESTAPP1, I am not prompted for authentication however, I am assigned yet another session ID after browser reload, different from the first.
So it seems that although authentication is carried across web applications, the session IDs as you move from TESTAPP1 to TESTAPP2 change, and then change again but not back to the original when going back to TESTAPP1.
This is a particular problem since we are using Vignette's V5 as our main client and tracking sessions through V5 - this would quickly become unmanageable if a single page view access three or four different application components with three or four different session ids.
I'm wondering if we can expect the same behavior from WLS 6.0?
Ideally, I'd like to see WebLogic use a single session ID to track users across multiple web applications but still have session independence between applications. So if I store something in session in TESTAPP1, its not available in TESTAPP2. Does this outline the behaviour in WLS 6.0? Can anyone verify this?
Some food for thought. Thanks!

Problem with ClassCastException in web application
Hello,
I'm trying to deploy a web application in WLS 5.1 and I'm getting the
"dreaded" ClassCastException every time when JSP tries to read a bean
from the request or session. Under my architecture (actually it's just
the regular "model 2" ) bean is populated by a servlet, set on the
request and then retrieved by JSP (servlet forwards to JSP). Everything
work fine when I register servlets in weblogic.properties, but
ClassCastException is thrown on any attempt to read from the request if
the same JSPs and servlets are deployed as web application.
Has anybody come across the same problem?
Thanks in advance for help.
Alexander
Hello,
This is all well and good as a temporary bug, but it's totally unrealistic for
the future. Two points:
* The ClassLoader doesn't need to be discarded, it just needs to be cleared.
* Other servlet engines seem to be able to handle this.
Hope it's on its way to resolution!

One Search service application for multiple web applications in a single server
We are planning to host 17 Web applications in a single Server. Do I need to create search service application for each web application or I need to create one Search service application , create a Content source for each web
application and create a Result source for filtering. Which is the best approach. And which approach takes more RAM memory.
In my application I am using Search web part, "Recently Changed Items", "Popular Items" web parts. when I created only one one Search Service application for all web applications and using Result sources ,
I am not getting the results. What could be the problem.Hi,
One SSA is ok, but you should think about access rights. If the access is clear cut between all the web apps you should be ok with one SSA. Multiple result sources limiting on content source also works, but could easily be bypassed.
Multiple SSA's will eat up RAM/CPU like a mother :)
As for popular etc.. it could be due to how those sources are set up, but haven't investigated or tested this much.

Problems access to a web application (Web Interface or Web report)
Hi,
We found problems with the access to web application. Some users have problems with direct links to the web applications(Web Interface or Web reporting), when they click on the link an error message appears, the message displays the following text:
"Cannot open file Bex?sap-language=ENbsplanguge=ENcmd=idoc_TE.."
Clicking in details the message is "No Access to specified file"
For this users the access to excel reporting is correct, the message appears when they click on the direct web links through the browser or directly in BW system, but if they type the URL they can access. Other users can use the direct web link without problems.
I highly appreciate any help or idea about how to solve this issue.
Thanks in advance.HI,
please ask to your basis that check the language of every single user on su01 tx.
This is the problem i think.

A web developer problem while running a web application
Hi all,
I'm novice to J2EE.
I've encountered a problem while accessing the deployed module in weblogic 8.1 server.
I'm sure that the webapplication module is deployed as i saw my module in administration console & also the status said that it is deployed.
when i access my web application by specifying the proper server and port no and context root it is showing
either 505 - resource not found error(http://localhost:7001/Suresh-2/Suresh) or 404 - not found error.( http://localhost:7001/Suresh-2/Suresh)
Now let me elaborate what i've done till now.
My webapplication folder structure is : C:\bea\user_projects\domains\mydomain\applications\Suresh\WEB-INF\classes\Sai\ServExamp.class
My servlet is ServExamp.java
I created a folder called "Suresh". In that folder created another folder called "WEB-INF". In WEB-INF created a folder called "Classes".
Since my servlet is in package "Sai", the .class file reside in \Suresh\WEB-INF\Classes\Sai\ServExamp.class
The source code is :
package Sai;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class ServExamp extends HttpServlet
public void doPost(HttpServletRequest req,HttpServletResponse res)throws IOException
PrintWriter out=res.getWriter();
java.util.Date today=new java.util.Date();
out.println("<html>"+"<body>"+
"<h1 align=center>HF\'s Chapter1 Servlet </h1>"
+"<br>"+today+"</body>"+"</html>");
Now i'm almost done creating a web application. Next, I constructed a simple web.xml descriptor that gives a web friendly name for my servlet, and points to the servlet. I constructed web.xml descriptor file in the WEB-INF folder (C:\bea\user_projects\domains\mydomain\applications\Suresh\WEB-INF\).
The web.xml file source is :
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Hello World Web Application</display-name>
<description>Test Servlet</description>
<servlet>
<servlet-name>ServExamp</servlet-name>
<servlet-class>Sai.ServExamp</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServExamp</servlet-name>
<url-pattern>/Suresh</url-pattern>
</servlet-mapping>
</web-app>
Now I have told Weblogic that the URI /Suresh corresponds to my servlet "Sai.ServExamp".
My Web Application is ready to be deployed at this point. I logged onto Weblogic's admin console,
1) clicked on deployments, then navigated to "Web Application Modules" .
2) Clicked "Deploy new Web Application Module"
3) Navigated to the location of your web application folder (Suresh). There was a radio button next to it indicating that I can select that folder as a valid web application.
4) I Clicked that radio button and clicked "Target Module".
5) It informed that my web application "Suresh" will be deployed to myServer.It asked a name for my web application deployment. By default it was "Suresh"
I clicked Deploy.
6) After deployment, my web application "Suresh" appeared in the "Web Application Modules" tree on the left.
I Clicked on "Suresh"( my web application) then clicked the testing tab, then clicked the link shown there(http://localhost:7001/Suresh-2).
It was not showing my servlet (showed a 403 error)
Error - 403
This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
I think so it came b'coz I don't have an index.html or index.jsp page.
7)Instead,I added my servlet on to the URL it provided.
http://localhost:7001/Suresh-2/Suresh
It is showing these error code: Http: 505 resource not allowed
The page cannot be displayed
The page you are looking for cannot be displayed because the address is incorrect.
Please try the following:
If you typed the page address in the Address bar, check that it is entered correctly.
Open the localhost:7001 home page and then look for links to the information you want.
Click Search to look for information on the Internet.
when i just type : http://localhost:7001/ -> Error 404 not found error
it's showing
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
I want to run my web application & any help would be appreciated.
Thanks in advance.
with regards,
S.SayeeNarayanan.
Note: I even deployed my war file, which i got by execution of (jar cv0f webapp.war . ) command from the root directory of my web application i.e. Suresh
Then executed my webapplication it is showing
error-505 resource not allowed.

Problem with layout in Web Application Designer
Hi all,
I am working with the BEx Web Application Designer. Well, I execute a web template in the browser, click on right button and choose enhanced menu, query properties and mark the check box Display Rows as Hierarchy and Expand to and from the list of values (combo-box) choose the last field that can be expanded.
Once all the lines have been expanded and the layout of the template is longer than a page, we look for a line that is not in the first page and contract it. The problem is that when we contract the line, the layout shows the first page, instead of the page where the line had been contracted. I have tried to solve this changing the properties that appear when the template is designed, but I haven´t found the solution. Is there any way so that i can solve it?
Thanks in advance,
Mª del Mar Bonilla.Bonilla,
Welcome to SDN...
Try this out...
In the Query designer view , right click on the rows structure and select display as hierarchy. In case this option works fine , the behavior pointed out by you could be a possible bug.
Just update the result of what I have mentioned above...

How to use a tag library in multiple web applications?
Morning all,
Environment: Tomcat 5 on Apache2 using Mod_JK connector on Windows XP
I have developed a custom tag library and tested it out and its working great.
Now, How do I use in my other web applications? Do I need to copy the JAR file to webapps\app1\WEB-INF\lib, webapps\app2\WEB-INF\lib etc directories?
The problem with this approach is, if I happen to change the tag library code, I will have to make sure that I remember to copy the new JAR file to the above mentioned directories. Ofcourse I can write a simple ant script that would do it for me, but I was wondering if there was an efficient and yet simple way of achieving the same.
Thanks in advance,
JoeThanks Vidyut! You've answered my question.
I placed the jar file in the $CATALINA_HOME/shared/lib directory. But where should I place the taglib TLD file? And how should I reference it in web.xml?
Currently, my web.xml is as follows and it doesn't work.
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<taglib-uri>http://abc.com</taglib-uri>
<taglib-location>c:\Tomcat\shared\lib\mytags-taglib.tld</taglib-location>
</taglib>
</web-app>
Thanks again!

Storing SessionManager or Server for multiple web applications
We currently have one enterprise application with 2 web applications installed. These 2 web applications must share the same session cache.
Toplink is installed as a shared library for both of these web applications.
What I am wondering is how Server and SessionManager should be utilized.
In our servlet initialization of web application one we get an instance of the SessionManager and assign the SessionManager to a static instance variable.
static SessionManager sessionManager;
sessionManager = SessionManager.getManager();
Now whenever we want to get a client session from either web application we make the call
Server serverSession = (Server) sessionManager.getSession("XXX");
From looking at the code for the sessionManager.getSession("XXX") I see that this
results in a synchronized method invocation which is in turn bottlenecking our database access code.
My question is should we not just be storing the Server in a static instance variable to distribute client sessions to both web applications and not the SessionManager.Hi,
One SSA is ok, but you should think about access rights. If the access is clear cut between all the web apps you should be ok with one SSA. Multiple result sources limiting on content source also works, but could easily be bypassed.
Multiple SSA's will eat up RAM/CPU like a mother :)
As for popular etc.. it could be due to how those sources are set up, but haven't investigated or tested this much.

Problem in installing SAP Web Application Server
Hi,
I have downloaded 90 days evaluation copy of "SAP Web
Application Java Server 6.40 SP7 for MS SQL Server". I
tried to install the same but invain. I am getting the
error as :
"MDB-05505 Look up in the check table returned no
result. ()".
The operating system that i am working is Win 2000
server.I have also installed JDK 4.1.2,MS SQL Server-7
and IE 5.5.
Please help me in resolving the problem.
Regards
Rajiv. VHi Rajiv,
The problem is most likely due to you needing to have SQL 2000 installed not SQL7.
In addition to this you need to ensure that your SQL has been installed with the correct collation and had the appropriate service packs applied.
Please let me know if you require further clarification.
Regards

IMAP/SSL: problem connecting from a web application
Hi,
I try to connect to a IMAP/SSL server (with a self-signed certificate) from a web application. I followed http://www.javaworld.com/javatips/jw-javatip115.html.
When I try to connect from a java application it works fine. But when I try it from a servlet, it fails:
javax.mail.MessagingException: gaeron.gcrm.test.mail.DummySSLSocketFactory;
nested exception is:
java.net.SocketException: gaeron.gcrm.test.mail.DummySSLSocketFactory
at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:461)
at javax.mail.Service.connect(Service.java:236)I use Tomcat 5.5, jdk1.5.0_06 and javamail-1_3_3_01. Here is my code:
Security.setProperty( "ssl.SocketFactory.provider", "gaeron.gcrm.test.mail.DummySSLSocketFactory");
Properties props = new Properties();
Session session = Session.getDefaultInstance(props);
Store store = session.getStore("imaps");
store.connect(server, 993, username, password);
store.close();Can anybody help me?
Thanks,
Előd.I am not sure there is a class called MBoxSSLFactory. Is that a typo? We are in the same boat. We have a web application running on Tomcat that needs to connect to the IMAP store on the MS Exchange 2003 Server. It was working fine until we enabled Basic Authentication - SSL/TLS required setting on it.
In order to eliminate any complications due to Tomcat and all we are trying to get a simple standalone program that talks to IMAP server (using the DummySSLSocketFactory, DummyTrustManager etc) working.
I am stuck on the same error: (shown below is the stack trace and the code we are running). I have tried all the suggestions that have been posted on this "Unconnected Sockets not implemented" issue. I have tried it with both Jdk 1.4.2_08 and JDK 1.5.0.
The JavaMail version is 1.4. If I use JavaMail version 1.3.1 it complains that there is no store type "imaps". If I use "imap" and not "imaps" as the store type I end up getting "Authentication Failed" exception.
Instead of a DummyTrustManager I even tried importing a certificate. We have deployed a Verisign trial certificate on the EXchange server side. So when we run the InstallCert program (http://blogs.sun.com/andreas/entry/no_more_unable_to_find) it allows us to add the valid certificates to our keystore. Once that is done we have tried to create TrustManager based on that keystore. But NOPE..No success. same problem.
We have been stuck on this one for the last 4 days and we have a very critical client deployment that is hampered by this one. I know it is turkey time now..but would really appreciate it if some one can help us out.
