An abstract database api for java

hi there
does somebody know if there is something like this around - I mean, an API, that works with abstract objects like tables, fields, rows, where-conditions, joins and so on, and then automatically generates the appropriate SQL-statements ?
java.sql is a quite low-level and implementation dependent API, I'd be glad to see an abstracter framework. anybody seen something like that ?

JDO? Though it provides for more than just portable queries, and doesn't provide any of the niceness of something like the RogueWave DBtools.h++ in terms of being able to build up a query procedurally, but it's a big step..

Data Warehouse:java.lang.NoClassDefFound Error while using OWB API for Java

I was writing code to use the OWB APIs for Java:
I have imported the folowing files:
oracle.owb.connection.RepositoryManager;
oracle.owb.connection.OWBConnection;
oracle.owb.connection.ConnectionFailureException;
when jvm tries to get instance of Repositary Manger by the following code
reposManager = RepositoryManager.getInstance();
I get the following exception:
Exception in thread main
java.lang.NoClassDefFoundError: com/objectspace/jgl/HashMap
I have checked my OWB and Java environment but I cant locate com/objectspace/jgl.jar file. Can some one tell me were this jar is located in so i can import it.

Either use some criteria you develop related to one of the keys on the table or use some sort of record limiting method.
Note the method of limiting will vary related to the database you are using. You will have to look at the documentation.
For example I am told this will work in MySQL to get 200 records starting at record 100.
SELECT * FROM myTable ORDER BY whatever ASC LIMIT 100,200
Because you are running out of memroy I assume the table is large,
I am not sure what the impact of the above will have on performance because if in the above if the order by is not based on an index at the server level all the records will be selected and sorted before the records are limited.
I would make sure you have an appropriate index.
If you use the advanced search over the user forums using "resultset paging" and possibility the database you are using you should be able to get some ideas.
I hope this makes sense to you.

JAXB as standard API for Java Mappings in XI?

Hi there,
Has anyone on this forum implemented Java mappings in XI using JAXB (reference implementation for XML/JAVA data bindings of SUN)?
If Yes, can you please share any experiences?
We're considering to use this API for Java Mappings in XI but first would like to get more background info.
Cheers,
Rob.

Hi Roberto,
Have tried implementing Java mapping using JAXB technique couple of years ago. However I was not able to test the mapping in XI/PI environment.
<ul>
<li>There is no in built support for JAXB from SAP XI.</li>
<li>There is no documentation available from SAP on JAXB hence it is difficult to implement the mapping.</li>
<li>We have to import JAXB specific jars along with the mapping code. my attempt to execute the mapping test in IR tool was unsuccessful It was running fine in standalone mode in local PC </li>
</ul>
[My question on SDN on same topic..|Java Mapping Using JAXB [Java Arch for XML Binding];
Thanks and regards,

Do you have JAVA_HOME set in your environment?
What's the result of

Make sure DBCA is calling the java under $ORACLE_HOME not from other installation.

Is there any Sun Java's official SVG API for Java SE?

Hi, I'm still learning Java and SVG.
Currently I want to build a kind of client-server application transferring SVG files.
I'm using JSR 226 to parse SVG files in my Java ME client, but I dont know what API I should use to parse SVG files in my Java SE server.
I want the server to read a large SVG image file and then parse it and divide it into some small linked SVG image parts before it can transferred to the client.
Does Java SE have a standard API for SVG? Bcause I only found Batik..
thnks in advance.

Hello,
I am using SVG Salamander... it is a nice small library.

Database statistics for Java system in CCMS (RZ20)

Hi All,
We have configured CCMS for JAVA system, but unable to view the Database statistics like Tablespace size, Free space, Backup, Performance etc., for it.
We are able to see these statistics for ABAP stack.
Is there any possible method (or) class to view these statistics?
We have even created a new rule-based monitor with class CCMS_DB_mcmtc and CCMS_DB_space_mscl but in vain.
Even if we cannot view these in RZ20, do we have any other methods like Netweaver administrator or Introscope or some other means....?
Waiting for some help......
Regards,
Phani.

I don't think there is any separation between CCMS and other systems, all use one database. If you use MaxDB use Database Manager, if smth like SQL Server or Oracle use standard tools of this vendors, like Enterprise Manager third party tools also helps you, cause I don't see any difference between

Require MS WORD API for Java

I am looking for a way to access only the attributes of a Word document. I don't need to access the document content, no reading or writing. Just read the attributes. Is there an API out there for this?
I've heard you can do this using a com-bridge, but I have no experience with this - is it easily done and should I venture it - is it worth the effort and can it actually done what I need?
I've heard from someone about a JWord interface, but couldn't find any info on it.
Thanks.

you could use a combination of a word macro and the ActiveX bridge. the activex bridge is for accessing java and the macro for reading the attributes and pass it over the activx bridge to java. btw: the activex bridge is removed in the latest J2SE.

SMD database monitoring for Java MSCS cluster system

Dear All,
We have install SAP netweaver 7.0 EHP1 java stack on oracle 10.2.0.5 with windows 2008 R2 MSCS cluster enviornmant.
now we are configuring SMD
From SMD, while configuring Managed system(JAVA ONLY system)--> database monitoring I am getting following error
DB connection Id :%_SID_virtualhost_SAPSR3DB
Connectivity test :
Database history :This connection could not be tested, thus the DB performance warehouse was not set up
Extractors activation :This connection could not be tested, thus the DB extractors were not set up
Connectivity test details :
Database connection %_SID_virtualhost_SAPSR3DB : SQL error 12505 ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
Database connection :%_SID_virtualhost_SAPSR3DB could not be established
System Details
Solman - SAP EHP 1 for SAP Solution Manager 7.0
managed system - Netweaver 7.0 ehp1AS JAVA(New Installation)
Connection parameters
Database Name: SID
Database Host :virtual host
TNS Name:SID.WORLD
User Name:SAPSR3DB
Password:xxxxxxxxxxx
Tns ping command is also not working when we give host name as virtual host of JAVA system
but when we change it to phyiscal IP address of the cluster server it is working fine.
Could you please let me know any setting need to be done
Sincerely
Paresh

Hi Paresh,
>> Tns ping command is also not working when we give host name as virtual host of JAVA system

>> SQL error 12505 ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
Virtual hostname must be resolved on both hosts while configuring SMD. Otherwise you'll not able to access Oracle Listener.

Need API for Java communicating with RS232

Dear All,
I am a newbie to Java. I have a sensor connected to a microcontroller, and this microcontroller is also connected to a PC through the RS232 (COM 1). I have installed the Java Communications API "Javax.comm" on my PC and was able to run the "BlackBox" sample program. What I require is a simple Java program that will read and show the bytes comming through the COM1 port. If anyone has done anything similar or has an idea of how to go about it, could they please send me some example code, I would be very grateful. Or if anyone knows about any website with such similar examples i would be very grateful.
Thank you very much.

Xquery API for JAVA

I have the following error in imports:

Where can i download the necessary jar files?
Best regards,

The Oracle databases, since 9 (and certainly 10) have an embedded Java VM in them.
That VM supports functionality that is not available elsewhere. Certainly not available in the standard Java VM (the one created by Sun and the one that the vast majority of posts in the java forums refer to.)
The root of your post appears at the following and looking through all of it may help.
