Problems in using tag libraries with JRun3.1

Hi,
I am new to JRun app server. I have a custom tag library named download. This tag library is used to download the files from the web server.
First i want to know, where i have to put my tag library in the JRun?
Second is there any configuration is needed to access it thru my jsp page?
I copy the jar file and paste it in WEB-INF/lib directory of the JRun server.
When i access my jsp page it gives the following error:
/test.jsp:
javax.servlet.ServletException: Parse Error in JSP page: The taglib directive on line 1 is not valid. The tag library descriptor 'download' could not be found.
allaire.jrun.jsp.ParseException: The taglib directive on line 1 is not valid. The tag library descriptor 'download' could not be found.

The jsp page contains the following code:
<%@ taglib uri="dloadtag" prefix="do" %>
<do:download file="Doc1.rtf"/>
The Doc1.rtf file is in the root directory of the web server.
Please give ur suggestions for this,
Adv. Thanks,
Sundar.

There should be some tld files that came with the tag lib. These need to be placed in the web inf folder.

Problem using JSTL tag libraries with OC4J 9.0.3

Hi
I'm using the JSTL tag libraries with OC4J 9.0.3. I'm using JDeveloper10.1.2. I put the fmt.tld and c.tld in the WEB-INF directory and I'm adding the jstl.jar and standard.jar library to the EAR file. Both tlds have:
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
And OC4J 9.0.3 is compatible with tlib version 1.0 and jsp version 1.2. When I run the web app I get:

Problems in using Windows Explorer with VPC Virtual PC?

Has anybody experienced problems in using Windows Explorer with VPC Virtual PC?
Lacking any "forbidden" or "appropriate usage" guidelines, I regularly use Windows Explorer (Windows 2000) to transfer file from the desktop. I have occasionally sensed that this might be wrong. Today I inadvertently clicked the MAC harddrive instead of the Desktop (within Windows Explorer) and caused all manner of mischief.
Any other views please?

Let me correct this:
I regularly use Windows Explorer (Windows 2000) to transfer files from the "Mac" desktop
Any ideas please Virtual PC VPC users?

Using external libraries with Developer Studio 7.1 Composition Environment

Hi,
I downloaded DS 7.1 CE and tried to develop a simple application which uses an external library.
I created a development component for "external library" for the local development -> MyComponent, giving it the name "test2" (for the domain basis).
I imported the external library file using Import -> File System , then selecting the .jar file.
In the component properties browser I added a public part naming it "mylib2" setting the purpose to "ASSEMBLY" (my intention was that the libarry will be transferred during the deployment to the application server).
I right clicked on the public part to "managed entities". I selected the archive tree and checked the library file shown there (the one I imported before). #
Then I opended component properties of my web dynpro project and clicked on "Dependencies". The I chose "Add..." and selected the "test2" development component I created before (see above).
Then I tried to deploy the project (which uses this external library) using "Deploy Archive and Run"
After deployment the browser window opens and shows the ClassNotFoundException
So what did I oversee or do wrong?
BTW: Is it necessary for using external libraries to use a full fletched NWDI? Or can I use external libs also with netweaver development environments freely available for download on sdn.sap.com?
Any hints?
Thanks a lot
Hannes

Hannes,
If you want to use external libraries with DCs then you should follow the NWDI completely.
Check this step, otheways of using external libraries is mentioned <a href="http://help.sap.com/saphelp_nw70/helpdata/en/e3/de813e77d46245e10000000a114084/frameset.htm">here.</a>

Can someone help me with this?
Thanks

Hi,
not sure if coincidence or the same question, but the same question got asked internally. The seeded option is required to get the OJSP filter installed. Here's the internal response
ADF View integration with MDS not configured
In web.xml, you need to have mds-ojsp intg enabled to load jspx base + customizations from MDS. In your web project in Jdev, go to ADFv project properties and select “Seeded customization” property. It would enable mds-jsp engine configuration in web.xml. If you want to use user personalization feature at runtime, you would need to select “User customization” property as well which would enable ADFv change persistence config in web.xml.
Warning: Some of the metadata under ... is packaged as part of both WAR and MAR. This metadata cannot be accessed from WAR using MDS.
For these two packages, you are including the files in both WAR & MAR. This warning conveys that since these base files are being put in MAR, at runtime they would be read from mds repository & not from WAR.

Problems with JSP - using tag library with Weblogic 8.1

I am getting the following error when I try to run a web application called "regain":
/searchinput.jsp(2): Error in using tag library uri='regain-search.tld' prefix='search': cannot find tag class: 'net.sf.regain.ui.server.taglib.MsgTag'
probably occurred due to an error in /searchinput.jsp line 2:
<%@taglib uri="regain-search.tld" prefix="search" %>
The classes that the .tld file points to are in the web applications WEB-INF/classes directory and I have put this path into my classpath environment variable (running Windows 2000 Server).
This application runs fine on Tomcat.
I can't not figure out whether is error is masking another error or what. I've tried using JDK and Jrockit for my web app - no luck.
Please help! Thanks!

anyone? :/

Problems in using Labview DLL with TestStand!

Hi,
I tried to put the VI's to create a TCP/IP Connection, read/write Data to it and close it inside a LabVIEW DLL and use these functions with TestStand.
The problem is to get access to the ConnectionID generated as TCP Network Refnum in LabVIEW.
I don't know how to specify the prototype entry for this Refnum in LabVIEW and how to read it with TestStand.
Another try to pass an ActiveXReference of SequenceContext and use the SetValIDispatch method to set a local variable (Type: ActiveXReference) to the returned ConnectionID of the TCPOpen.VI wasn't successful too.
It seems to me that the connectionID isn't a normal ActiveXReference.
Regards,
Sunny

Hi Sunny -
You should treat this parameter as a pointer to an int when calling the DLL from TestStand (or any language like C or C++). Note that you can't do anything with the value outside of LabVIEW since it only has meaning inside of LabVIEW. You can only pass it around for use in other VIs you call from TestStand.
Hope this helps....

Using Multiple Libraries With iTunes 7.5

I recently updated to 7.5, using multiple libraries does not work anymore. The dialog to choose library if holding the option key while opening itunes will not appear anymore. anyone having a similar problem? Multiple libraries are a necessity for me.

I am also having this problem. I tried to create a separate library, but when I followed the directions (hitting shift when I open iTunes) I did not get the option to do so. My regular account just opens. Have you resolved your problem yet?

Using Javascript libraries with OBIEE 11g

Hi,
I want to use javascript libraries like scriptaculous.js in OBIEE. I placed the libraries in the location {Middleware_Home}\Oracle_BI1\bifoundation\web\app\res\b_mozilla. But when I try to use the library I am getting the "Failed to load" error message. Is that the correct location for placing library files?
Thanks,
KK

You need to add the .js file in two locations
1. \MIDDLEWAREHOME\Oracle_BI1\bifoundation\web\app\res\b_mozilla
2. \MIDDLEWAREHOME\user_projects\domains\bifoundation_domain\servers\bi_server1\tmp\_WL_user\analytics_11.1.1\7dezjl\war\res\b_mozilla
Let me know if it works...

Problem with using J2EE libraries with a team enviroment

Hi all,
I've created two portal web projects one as a shared library to share portal resources.
I've followed the steps to create a J2EE shared library (for portlets for example) by modifying
META-INF/MANIFEST.MF file with the variables added to it and exporting the WAR file to be imported into the
second project (portal project).
I can see the portlets in the available portlots from the portal project but I can't use them as I get the following
error:
No such portlet with URI (Portlet Name).
Did I miss any steps to be able to use the portlets from the shared library into the portal project.
Any Help?
Many Thanks in advance.
Mohamed

Try the WLP forum:
WebLogic Portal
Also I would be more specific with your question showing the contents of the shared library with concrete names / URL's you are using, etc.

Problem in using socket streams with encryption and decryption

Hi,
I am developing a client/server program with encryption and decryption at both end. While sending a message from client it should be encrypted and at the receiving end(server) it should be decrypted and vice versa.
But while doing so i got a problem if i use both encryption and decryption at both ends. But If i use only encryption at one (only outputstream) and decryption at other end(only inputstream) there is no problem.
Here is client/server pair of programs in which i am encrypting the outputstream of the socket in client side and decrypting the inputstream of the socket in server side.

**** I know that the CInput tries to read some header stuff thats why i used two threads for input and output.
Waiting for the reply.
Thank you.

Do not ever post your code unless requested to. It is very annoying.
Try testing what key is being used. Just to test this out, build a copy of your program and loop the input and outputs together. Have them print the data stream onto the screen or a text file. Compare the 1st Output and the 2nd Output and the 1st Input with the 2nd Input and then do a static test of the chipher with sample data (same data which was outputted), then do another cipher test with the ciphertext created by the first test.
Everything should match - if it does not then follow the steps below.
Case 1: IO Loops do not match
Case 2: IO Loops match, but ciphertext 1st run does not match loop
Case 3: IO Loops match, 1st ciphertext 1st run matches, but 2nd run does not
Case 4: IO Loops match, both chiphertext runs do not match anything
Case 5: Ciphertext runs do not match eachother when decrypted correctly (outside of the test program)
Problems associated with the cases above:
Case 1: Private Key is changing on either side (likely the sender - output channel)
Case 2: Public Key is changing on either side (likely the sender - output channel)
Case 3: Private Key changed on receiver - input channel
Case 4: PKI failure, causing private key and public key mismatch only after a good combination was used
Case 5: Same as Case 4

Problems in using a certificate with different versions of JVM

Hi friends,
I am facing a typical problem:
I have to use a certificate which uses the sha1DSA signing algorithm to contact a web service(I am coding a client). I was using J2SDK_1.4.1_02 before. I added the certificate to keystore and it was working fine. But if I upgraded my JRE to 1.4.2_13 the same code doesn't work,. I got the following exception:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found

Hi Michal,
Keeping in mind the recommendations of the Production Checklist...
All other things being equal, homogenous deployments are usually less prone to surprises.
But JDK 1.6 is noticeably faster than JDK 1.4, and features much better JMX support as well, so it's a probably the better option.

Problem in using sybase drivers with JDK 1.5

hi all,
i have an app that is connecting to a sybase database.
so far i have run it using jdk 1.4 using sybase jconn2.jar , it has workedf ine.
Now, i haven't changed the code, i just recompiled it and re-run it using jdk 1.5 , and suddenly i am getting a classNotFoundException

and NOTHING has changed except that now i am runnign java 1.5 instead of 1.4
has anyone ever experienced a similar problem?
regards
marco

Hello,
well, yes it is.
Running the code with jdk 1.4 is absolutely fine.
if i run it like this
<myjdk14install>\bin\java -jar xxx.jar works fine
if i run it l ike this (which will use 1.5 by default)
java -jar xxx.jar it gives me that exception...
have the classloading mechanism changed between jdk 1.4 and jdk 1.5?
regards
marco
