Prolog in Java. (does it exists ?)

I�m working with first order predicates unification and I had implemented a simple inference machine here....
Do you know if is there any 100% Java Prolog-like code available at any place in the web ?

Hi,
why not bringup a search engine like yahoo.com and enter java prolog and press the search button? - There is at least one, but search by yourself, I can't decide, what you need and what not.

Java.lang.IllegalArgumentException: Session: null does not exist

These days I am getting an exception (java.lang.IllegalArgumentException: Session: null does not exist) when I restart the weblogic managed server. I have a work around to get away with this error. I completely delete the dataspace from ALDSP console and redeploy the artifacts jar file. This is a tedious process. Can anyone suggest a permanent fix to resolve this issue.
ALDSP version: 3.01

Thanks.

Java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist while invoking a DBAdapter

I have a WebService which is invoked , the request is routed through the mideator to the DBAdapter .DBAdapter interacts with the database and replies the result.
I send in the CreditCardNumber in the request and recieve its Status (VALID,INVALID). i get this error every time . i have tried almost every thing to fix this . Please help me with same .
Below is the complete error stacktrace.
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'getCreditValidationSelect' failed due to: DBReadInteractionSpec Execute Failed Exception. Query name: [getCreditValidationSelect], Descriptor name: [getCreditValidation.Creditcardinfo]. Caused by java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist . See root exception for the specific exception. This exception is considered retriable, likely due to a communication failure. To classify it as non-retriable instead add property nonRetriableErrorCodes with value "942" to your deployment descriptor (i.e. weblogic-ra.xml). To auto retry a retriable fault set these composite.xml properties for this invoke: jca.retry.interval, jca.retry.count, and jca.retry.backoff. All properties are integers. ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
Thanks in advance

Can you please check the following
a. check the JNDI Configuration. ( check for the value used for XADatasourceName )
b. check the Data source created for the User.
c. Incase you have updated the existing JNDI then you need to update the adapter with the New Deployment Plan.
Thanks,

Keytool error: java.lang.Exception: Keystore file does not exist:

Hi All,
While listing the keystore using the command keytool -list, I got the error message that
keytool error: java.lang.Exception: Keystore file does not exist: C:\Documents and Settings\subramanian.arivalag\.keystore
I noticed there is no file .keystore in the above mentioned directory. What's this .keystore file? Will it be created automatically or should we create manually?
Already I created a keystore using -genkey command and received CA authority also.
Kindly provide me more details about .keystore file and how to handle this error.

If you specified a keystore filename when you created the keystore
i.e. keytool -genkey -alias jboss-ssl -keyalg RSA -keystore my_name.keystore -validity 3650
then you need to specify the same keystore when you export the cert
i.e. keytool -export -alias jboss-ssl -keystore my_name.keystore file my_name.cer

WD Java - Type does not exists

Hi folks,
we use the RFC Import in WebDynpro JAVA and import a function module of name like /tyed/myFunction where /tyed/ is a namespace.
when running that application we get an error on a structure which is of name like /tyed/myStructure and in JAVA the namespaces are translated from /tyed/ to __tyed__
The dump says com.sap.dictionary.runtime.DdException: Type ordmon.types.__Tyed__Atcp_S_Ordmon does not exist
But these data-types do exist? are there any known problems with namespaces ???? or what could that be.
kind regards
oliver

Hi Oliver,
The most likely reason for this kind of an error could be the follows
The backend to which to connect at Runtime is not the same as the backend from which you imported the model. This could cause inconsistencies. You need to run with the same backend from where you imported your model or the version of the RFC in the backend used at runtime must be compatible to the one used to import the model.
Data types have changed in the backend, such that the Type you imported earlier no longer exists. You need to re-import the model again.

Arun

"package java.xml.registry does not exist" error in NetBeans

Hi all
I'm using netbeans for developing webservices and and have to use JAXR. I have downloaded and installed jwsdp1.5.
When I view the source code for the JAXR sample java files that accompany the java EE tutorial in the NetBeans IDE Source Editor, I get the error : package java.xml.registry does not exist.
However, the release note for NetBeans says that it supports JAXR.
Also, when I compile and run the same files using DOS and the ant command, the files work.
Can someone please tell me what to do and how to work on JAXR clients in NetBeans because the Help files don't have any documentation on it nor does the NeBeans Field Guide?

Do you have the jaxrpc-api.jar and jaxprc-ri.jar in your classpath?
They are in <wspack1.1 installation>/jaxrpc-1.0.2/lib

Java.media.* does not exist

Hello friends,
I am adding a new project in the netbeans5.0 using the
Java Project with Existing sources.
Then i add the source file.
Before doing this i am using the library manager and add the jmf.jar files and also i am setting the CLASSPATH in the home directory.
Then at last i am giving the build it tells the problem of java.media.* does not exist.
I don't know what to do further.
I am also setting the JMFHOME,CLASSPATH,PATH ,LD_LIBRARY_PATH.
After that also it tells the same problem.
Kindly tell what to do next for solving this problem
With Regards,
deepthi

Hello friends,
I found the problem of javax.media.* does not exist.
You had to add the library path to your projects,
I here tell how to add the library path for you netbeans 5.5,
In netbeans 5.5
In the left panel, it list your projects,
Steps to add :
1.Click on the project.
2.Now it displays the tree list of source packages,library,
3.Right click on the library ,
4.click on the Add Jar/projects,
5.Then enter the jar files [ jmf.jar,sound.jar ,etc ].
Now you compile and run .
It works fine for me try for yours.
If you place the javax directory in you source file remove that directory from the source package.
With Regards,
Rohini [ deepthi ]

Error : java:6: package com.crystaldecisions.sdk.framework does not exist

Hi All,
I am using BO XI R2 version.
I am facing issues with BOE Java SDK web application.
In this application, I have just by-passed login page(jsp page) and logout from BO. But, it is throwing errors as mentioned below:
Generated servlet error:
E:\BusinessObjects\Tomcat\work\Catalina\localhost\_\org\apache\jsp\BO_005fHello_005fWorld\login_jsp.java:6: package com.crystaldecisions.sdk.framework does not exist
import com.crystaldecisions.sdk.framework.CrystalEnterprise;
Application gives errors for these two packages:
package com.crystaldecisions.sdk.framework
package com.crystaldecisions.sdk.exception
Can anyone please tell me the solution?
From where I can get the jar files to resolves these problems?
I tried to search these jar files in BO installation folder but was not able to get.
Can anyone tell the exact folder path for these jar files, if it is there.
Or any link to download jar files.
Thanks in advance.

Hello ,
-In order to run your application, please copy the Business Objects JAR files from the installed location.
-For example : If you have installed Business Objects on C:
then , go to the path :
C:\Program Files\Business Objects\common\3.5\Java\Lib and copy all the Jar files from that location including JAR files that are present in the external folder.
-Paste these JAR files inside lib folder of your application.
-The class com.crystaldecisions.sdk.framework comes under cesession.jar
Thanks,

When compiling servlets etc, you need to include in your classpath a jar file with all the javax.* classes defined in it.
For Tomcat this is called servlet.jar and is in (I think) [TOMCAT_HOME]/shared/lib or /common/lib
For J2EE 1.4 Server, the jar is [J2EE_HOME]/lib/j2ee.jar
Where the _HOME directory is the directory where you installed J2EE.
Include this jar file in your classpath when compiling.
Good luck,

System configuration is EP7, Oracle database.
Could you please assist me to resolve this issue.
Thanks & regards,
Pavan.

Hi,
you have to map the EP user to an employee at the backend for the ESS services to work.
Go to transaction HRUSER and check whether an employee is connected to this USER_ID.
If it is not there, go to transaction pa30,select an employee and create a new record for the infotype 105 ( subtype 0001) with the USER_ID.
Check the start DATE and the END date of the same PERNR of infotype 105 subtype 0001
This will solve the issue.

Java.math package does not exist!!!

hi java experts, i really desperately need some help. ihave been trying to compile a java program i have written that imports the java.math package as i am using the BigInteger class. I am using SUN ONE STUDIO ME 4 and have j2se SDk installed. when i try to build the program in the IDE, it gives me an error message saying the java.math package does not exist. i can't understand why. i think it's an IDE problem. i tried mounting the filesystem and i mounted almost a million times in diff ways but it still can't compile. i can't find the directory of the java.math to mount into. anyway i tried to compile it at the command prompt and it can compile but with errors... so i figure that i do have the java.math class on my system just that the IDE jsut can't recognise it. i am at my wits end and gonna go mad if someone doesn't please help me.

java.math package will be there in jdk_dir\jre\lib\rt.jar. You need to set the classpath variable in your IDE for this jar file. There must be some means to edit the IDE's classpath variable.
i mounted almost a million times in diff ways but it still can't compileIf it takes one minute for each mount then total time you have taken = 10000000 minutes = 166666 hours = 6944 days = 19 years (roughly). Java was not there 19 years ago.
