How does weblogic render portal skeleton jsps?

Hi,
how does weblogic render shell?
below is my shell file fragment,
<netuix:head/>
<netuix:body>
<netuix:header>
<netuix:jspContent contentUri="/framework/skeletons/header/pageHeader.jsp"/>
</netuix:header>
<netuix:jspContent contentUri="/framework/skeletons/navigation/topMenu.jsp" />

<netuix:footer>
<netuix:jspContent contentUri="/framework/skeletons/footer/pageFooter.jsp"/>
</netuix:footer>
</netuix:body>
Do all jsp (pageHeader.jsp, topMenu.jsp, leftMenu.jsp, pageFooter.jsp) rendered parallaly or they rendered as per the flow (as they defined in shell)?
If I set any request attribute in head.jsp or pageHeader.jsp, will it be available in topMenu.jsp or leftMenu.jsp?

Ellen,
I am not clear about your question.
User A will only see the data which is retrieved based on it's principal
name (I assume you use principal name as an argument to retrieve the data
from DB).
If you are using p13n cache make sure the principal name is part of the key.
Please provide more details if you see that I did not understand your
question.

Michael Goldverg

My application has multiple portlets which need to display very sensitiveuser
data.
These portlets read user principles from session (e.g. <weblogic:getproperty>)
and make calls to an EJB to retrieve data from database and display theseuser
specific data.
I didn't specify any synchronize in my code. My concern is when two useraccess
the portlet at the exact same time, will user A see user B's data?
Any suggestions or general guide lines about synchronize in portal will bevery
helpful.

The test-frequency-seconds property specifies the number of seconds between tests of unused connections. WebLogic Server tests unused connection and reopens any faulty connections. You must also set the Test Table Name.
The seconds-to-trust-an-idle-pool-connection property specifies the number of seconds within a connection use that WebLogic Server trusts that the connection is still viable and will skip the connection test during the periodic connection testing process.

How does WebLogic 8.1 get the BASE HREF value?

We have a WebLogic 8.1 SP4 server with a Juniper DX load balancer in front. We are trying to get Juniper to handle all the SSL traffic for the WebLogic application. Between Juniper and WebLogic, it would be just HTTP and between Juniper and web clients it would be HTTPS. One of the main issues we are seeing is that Struts HTML:BASE tag is returning the Juniper address as we expected, with the correct SSL port and application context/paths. However, the protocol for this base href is set to HTTP and not HTTPS. Consequently, our pages do not load properly.
I am trying to understand where this value comes from. The underlying code uses request.getScheme() to get the protocol. So, we could "customize" the tags to work around this, but that is a hack that I am trying to avoid. I assume that the HTTP stack that WebLogic 8.1 uses is providing this info from the HTTP request. Does this come from the web browser? How does WebLogic get this to put it into the request object in the web container? We have sniffed the HTTP headers on the web client side and we cannot see where this is coming from.

I remember facing a similar issue with webloigc 8.1 and apache
I dont think its a problem with the tag..
I think i have changed the transport-guarantee in web.xml
If you have NONE try setting that to CONFIDENTIAL and vice versa

How does weblogic maintain idle JDBC connection

I see weblogic maintaining connections even when they are idle. (unless we explicity mention to remove)
How does weblogic maintain the socket on DB under idle condition? Does webogic do ping kind of activity to maintain/renew the socket for all idle connections in the pool.

The test-frequency-seconds property specifies the number of seconds between tests of unused connections. WebLogic Server tests unused connection and reopens any faulty connections. You must also set the Test Table Name.
The seconds-to-trust-an-idle-pool-connection property specifies the number of seconds within a connection use that WebLogic Server trusts that the connection is still viable and will skip the connection test during the periodic connection testing process.

How does *.jsf extension map to *.jsp extension and where it is mapped

Hi ,
How does *.jsf extension map to *.jsp extension and where it is mapped ?
Thanks

How does *.jsf extension map to *.jsp extension and where it is mapped ?It is mapped in the web.xml.
If you add the following in your web.xml:
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>
The *.jsf will be mapped to the file with the same name, but xhtml as extention.
if you the javax.faces.DEFAULT_SUFFIX is not defined in the web.xml, the default suffix comes from the one of the constant of javax.faces.application.ViewHandler . This constant names DEFAULT_SUFFIX and equals to ".jsp"
Look at:

How does WebLogic know it needs XA transaction?

I've been informed that Weblogic 8.1 "knows" whether it needs to start a global XA transaction or not when it starts a transaction...sparing the overhead of an XA transaction if it is not needed.
          Is this a true statement?...and if so...how does it know that distributed resources will be used in the transaction when it is starting the transaction?
          The main reason I ask is that we are wondering if there is any way to avoid using the XA driver for "every" transaction, when we only need it less than 1% of the time. We would like to avoid the overhead that is introduced with XA.

WebLogic always performs XA operations, it looks at the resource and checks if it implements the XAResource interface, if it does it uses the XA operations with that resource otherwise the operations will just be a null op.
          So it depends on what resources you use in the tx. If you mix, XA and Non-XA resources in the tx, you may hit heuristic exceptions and inconsistentcies in your data which you will have to manually correct. Also you loose the ability to recover any transactions.

How does OBIEE render international character sets?

Hi.
Our OBIEE Oracle Business Intelligence 11.1.1.5 application running on Linux x86 (64-bit) and a 11.2.0.2.0 database is using the AL32UTF8 Unicode character.
So our database will support languages such as Japanese, Spanish etc.
But how does OBIEE deal with these? How do the webpages know that the content is UTF8 also?
Thanks for any tips -

How does WebLogic clean up stuck threads?

Hi,
Using WebLogic 9.2.2 on Linux OS. In our logs, we are finding some stuck threads and it seems to be due to something WebLogic is doing. While we don't understand the cause (maybe the stack trace helps), does WebLogic do anything to remove stuck threads from its pool, or is there anything we can do to configure it to?

You can configure these actions to occur when not all threads are stuck, but the number of stuck threads have exceeded a configured threshold:
* Shut down the Work Manager if it has stuck threads. A Work Manager that is shut down will refuse new work and reject existing work in
the queue by sending a rejection message. In a cluster, clustered clients will fail over to another cluster member.
* Shut down the application if there are stuck threads in the application. The application is shutdown by bringing it into admin mode. All
Work Managers belonging to the application are shut down, and behave as described above.
* Mark the server instance as failed and shut it down it down if there are stuck threads in the server. In a cluster, clustered clients that
are connected or attempting to connect will fail over to another cluster member.

How does LabVIEW Render the data in 2D Intensity Graphs?

Hello,
I was hoping someone could explain to me how LabVIEW renders it's 2D intensity data. For instance, in the attachment I have included an image that I get from LabVIEW's intensity graph. The array that went into the intensity graph is 90000x896 and the width/height of the image in pixels is 1056x636.
Something I know from zooming in on these images as well as viewing the data in other programs (e.g. Matlab) is that LabVIEW is not simply decimating the data, it is doing something more intelligent. Some of our 90000 lines have great signal to noise, but a lot of them do not. If LabVIEW was simply decimating then our image would be primarily black but instead there are very obvious features we can track.
The reason I am asking is we are trying to do a "Live Acquistion" type program. I know that updating the intensity graph and forcing LabVIEW to choose how to render our data gives us a huge performance hit. We are already doing some processing of the data and if we can be intelligent and help LabVIEW out so that it doesn't have to figure out how to render everything and we still can get the gorgeous images that LabVIEW generates then that would be great!
Any help would be appreciated! Thanks in advance!

Hi Cole,
Thank you for your understanding. I do have a few tips and tricks you may find helpful, though as I mentioned in my previous post - optimization for images or image-like data types (e.g. 2D array of numbers) may best be discussed in the Machine Vision Forum. That forum is monitored by our vision team (this one is not) who may have more input.
Here are some things to try:
Try adjusting the VI's priority (File»VI Properties»Category: Execution»Change Priority to "time critical priority")
Make sure Synchronous Display is diasbled on your indicators (right-click indicator»Advanced»Synchronous Display)
Try some benchmarking to see where the most time is being taken in your code so you can focus on optimizing that (download evaluation of our Desktop Execution Trace Toolkit)
Try putting an array constant into your graph and looping updates on your Front Panel as if you were viewing real-time data. What is the performance of this? Any better?
The first few tips there come from some larger sets of general performance improvement tips that we have online, which are located at the following links:
Tips and Tricks to Speed NI LabVIEW Performance
How Can I Improve Performance in a Front Panel with Many Controls and Indicators?
Beyond that, I'd need to take a look at your code to see if there's anything we can make changes to. Are you able to post your VI here?

How does weblogic work on JView ????

Hi,
The startweblogic.cmd file has options where I can use Microsoft's JVM
for weblogic.
But How could this be ?? because Microsoft's JVM does not support RMI
... but weblogic can deploy EJBs which is based on RMI ??
Has anyone thought about this ?
regards,
Abhishek.

WebLogic uses its own RMI implementation so it does not depend on the
JVM for this.
However, I would not recommend using Jview unless you have to do it.
It's still a JDK 1.1 JVM.

How does Weblogic find out which webservice method to invoke?

Hi!
I developed a webservice which is currently running on weblogic & everything is fine ;). Yesterday I tried to get it running on a different app server (jboss) and it simply would not work. I always got an error, that the operation requested does not exist on the endpoint. I investigated the issue & came to the conclusion that it is correct...the operation requested does really not exist. Now...why does it work on weblogic?!?
Here a few details on the application:
important part from the wsdl & xsds:
<wsdl:message name="performTransactionSearch">
<wsdl:part name="parameters" element="tns:performTransactionSearchRequest" />
</wsdl:message>
<wsdl:portType name="TransactionService">
<wsdl:operation name="performTransactionSearch">
<wsdl:input message="tns:performTransactionSearch" />
<wsdl:output message="tns:performTransactionSearchResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="O2HWOnlyJournalServicePortBinding" type="tns:O2HWOnlyJournalService">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http"
style="document" />
<wsdl:operation name="performTransactionSearch">
<soap:operation soapAction="" />
<wsdl:input>
<soap:body use="literal" />
</wsdl:input>
<wsdl:output>
<soap:body use="literal" />
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
And here the xsd type:
<xs:element name="performTransactionSearchRequest" type="tns:performTransactionSearchRequest"/>
<xs:element name="performTransactionSearchResponse" type="tns:performTransactionSearchResponse"/>
<xs:complexType name="performTransactionSearchRequest">
<xs:all>
<xs:element name="RequestHeader" type="base:requestHeader" minOccurs="0"/>
<xs:element name="TransactionSearchCriteria" type="wstypes:transactionSearchCriteria" minOccurs="1"/>
</xs:all>
</xs:complexType>
<xs:complexType name="performTransactionSearchResponse">
<xs:sequence>
<xs:element name="SearchResponseItem" type="wstypes:searchResponseItem" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
Last but not least, the method:
public List<SearchResponseItem> performTransactionSearch(RequestHeader header, TransactionSearchCriteria criteria) { ... }
The difference in the soap request messages differs in the outer tag. Weblogic expects what is defined in the xsd -> <performTransactionSearchRequest>, whereas jboss expects the operation/method <performTransactionSearch>.
With jboss it only works w/o the 'Request'-suffix....with Weblogic it only works with the suffix.
In a last attempt I adjusted the xsd, and changed the name for the tag to 'performTransactionSearch'. In that case, both app servers accept the same request (the one w/o the 'Request'-suffix) & it works fine.
Now...long story short ;) ... why is that? I understand why Jboss is not able to work with the "wrong" tag, even though it is strange that it accepts a tag that is not even defined in the xsd.
But, at least to me, I found it even stranger, that weblogic "knows" which operation to invoke. Can anyone give a little insight how a soap message gets processed in wl & how wl finds out which operation to invoke?
Many thanks in advance :).

Hi
I am seeing frequent FULL GC This is because you are creating and destroying objects VERY frequently. Try to look at your design and see where you can reuse objects (i.e. object pooling) if possible, that is if this is adversely affecting performance.
and not able to locate
which particular class/method is calling the
System.gc(). Classes don't call GC. The VM handles that automagically.
I have disabled it using
-XX:DisableExplicitGC and performance issues have
been resolved. Also, I noticed that it does not
happen periodically, so it is not RMI GC. How to find
out who exactly is doing this? Does any of of the
profilers like Optimizeit/Jprobe help find out this.OptimizeIt will tell you everything you need to know. However, NetBeans offers a free profiler now!

How does Weblogic 7 check for well-formed xmls

Hello,
I am having trouble deploying my applications with WLS 7.0. The error I am getting
is that my web.xml is not well-formed, but I have double-checked everything and
I think it is correct.
I have read that weblogic 7.00 does not deploy an application which xmls are not
well-formed (whereas earlier versions of weblogic would do so).
My question is: against what dtds does WLS 7 check the web.xml, the weblogic.xml
, etc.? I would think that it would check it against the dtd in the head of the
xnl file, i.e., http://java.sun.com/dtd/web-app_2_3.dtd for the web.xml, is this
correct?
If this was true, what about intranet applications that are not connected to the
Internet? could this be the reason?
TIA Cristina Ceballos

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader(xmlString)));try/catch this ugly line, if no parse exception and a non -null doc exists then your XML is well-formed.
of course if your XML contains namespaces, you would have to setup correctly the document builder.

Where does WebLogic search the compiled JSP files?

Hi,
          I have done several tests with WebLogic and JSP files.
          I have observed that when the JSP is requested the first time it is
          compiled and saved in c:\weblogic\myserver\classfiles\jsp_servlet
          If I request the same JSP again, it won't be compiled again. I
          suppoussed it was because the compiled JSP (*.class) was created. Then I
          deleted the compiled JSP and when I call the JSP again it run perfectly
          without a new compilation.
          Where are really those JSPs?
          Thanks in advance,
          Chemi.

          No clue. But as somebody else has said, touching the jsp files WILL
          force recompilation if you gor your JSP engine setting correct (check
          seconds set to zero).
          My guess is that all AppSrv would have this feature, because it comes
          for free with usual classloaders, i.e. it would be MORE trouble to not
          have this feature than to have it.

Which DDL does Weblogic use?

How does weblogic determine which DDL to use when creating JMS persistent store?

How does weblogic determine which DDL to use when          > creating JMS persistent store?
          The DDL is stored in the weblogic.jar, and a particular DDL is chosen automically based on driver meta-data.
          Version 9.0 (out in beta), provides the option of administratively configuring the DDL file location.
          For unsupported drivers, versions prior to 9.0 require manually running a DDL file to create the JDBC store's backing tables (see JMS doc).

Does Weblogic Portal Server provides caching services and multilingual support

I wanted to know whether Weblogic Portal Server 8.1 has got the facility for caching
services and multilingual support?

is this JSF-portlet.jar bridge file used to create .portlet file from the JSF file so that the portlet file may be added in the portal?
And if you were able to solve the issue by removing the bridge jar file itself, how does that help? if that is the one that would help in creating portlets.
If anyone have been able to create a .portlet file from JSF and deploy in Weblogic 8.1, let me know.
Thanks,
-RAJIV.
