Resources for developing java UDFs used in XI

I am with some Java background working in XI
for developing Java UDFs used in XI are there any online resources or books other than from the SAP help and SAP certification material.

Hi Kalyan
You can get a lot of UDF already discussed in Forum and Blogs, Wiki
As you said you are familiar with Java then you wont find any difficulty

Can't find resource for bundle java.util.PropertyResourceBundle, key Summar

While invoking a specific reprot file using JRC API, i am getting the below exception. Can you anybody tell me what jar file or properties files are requried to be placed in the lib folder? I can send the total stack trace if requried.
- Failed to load the resource 'SummaryOnNonRecurringField' from the bundle java.util.PropertyResourceBundle@5e9d7a.

Hello Srinivasa,
-Have you used any database connectivity for your report (like JDBC or ODBC)? Does your report work fine from designer ?
-The reason you are getting this error might be that the u201Cojdbc14.jaru201D or the JDBC driver type jar file you are using might not be present in the u201CCRConfig.xmlu201D class path location.
-For resolving this error message, please add the u201Cojdbc14.jaru201D to the CRConfig.xml file class path present in the folder u201CC:\Program Files\Common Files\Business Objects\3.0\javau201D for CR XI.
-Also, please make sure whether you have copied the JDBC driver to the WEB-INF\lib folder.
-Apart from this.please make sure that you have copied all the JAR files from business objects lib folder inside lib folder of your application.
Thanks,
Chinmay

Hi Vijay,
Thanks for the quick reply.
I have gone through the notes 1535201 & now on 1606563 after your advise.
Both the notes says the fix is available on 7.01 after SP 07 and we are on SP 14 already.
Also just in case I did checked with our basis and they confirmed we are a head and we have the above notes in our release already.
Unfortunately the notes are not the solution to the investigation till date.
Thanks,

Which is the best and user freindly IDE for developing Java GUI application

Please advice me if there is any good IDE for developing all kind of Java applications.
I m confused about which IDE to use.
I have Searched on Net also. and most of the answers i found was for JBuilder and JBoss.
But cant confirm until u guys suggest me.
Because i think this is the best place to ask questions about java.
Please advice

If you're developing JSPs and Servlets....
I've found that using Eclipse (which is free) coupled with the MyEclipse plug-in (an advanced J2EE specific plug-in which costs $29.99USD/year) was the best for me. I've tried several free J2EE Eclipse plug-ins, didn't like them. Wasn't a big fan of NetBeans either, but I liked it tons better than the other Eclipse plug-ins.
Therefore, IMHO for free I'd go with NetBeans, for a small fee I'd go with Eclipse/MyEclipse plug-in.
If you are new to J2EE but not to Java, you may want to consider going straight to JSF and Sun's Java Studio Creator. This is not free, but the fee is one-time and development is (mostly) visual using Java Studio Creator.

Coding standards for developing java iviews

Hi All,
Are there any coding standards to be explicitly followed to develop Java iviews in SAP Enterprise Portal ? Does SAP has any specific java coding standards to get the SAP certification for the developed iviews ?
regards,
sreeram

Hi Sreeram,
> Are there any coding standards to be explicitly
> followed to develop Java iviews in SAP Enterprise
> Portal ?
No. What you can find (for example within the PDK doc or partially created by wizards) are templates for the different kind of iViews, especially for JSPDynPages. But you have to care - even these templates are not really "clean" - there are objects used to store data which shouldn't...
> Does SAP has any specific java coding standards to get
> the SAP certification for the developed iviews ?
No. What is needed is the proper use of namespaces, but this primarily concerns portal objects within the PCD. Some implementation things are to be considered, for example if i18n is offered, it really has to work. But SAP does not care about the source code of the iViews.
Hope it helps

Resource for developing custom scripts

I am looking for a resource to develop some custom scripts in illustrator to automate the creation of production files from design mock-ups. If anyone is an expert or knows an expert in scripting I would love to connect.

here's the official documentation

Resources for first java soap client/server endeavour?

Hello community,
Im looking for some good resources for setting up a soap server, on apache tomcat, to handle incoming soap messages and send a soap response to the client.
Any links to examples/sample code are greatly appreciated. I am completely new to webservices.
your help is appreciated, thank you.

Christ, how did I mange to make those typos?
You need a webserver to accept the requests, and something like Tomcat to run your web service. Since Tomcat has a webserver (doesn't it include Apache?) already, Tomcat is all you need, but it won't really care whether you send some XML using HTTP or HTML form data using HTTP. It's still HTTP.

Good resources for learning how to use Aperture's adjustments

I'm a long-time visual artist who is just now getting into photography. I own both Lightroom and Aperture, and I must say that, for me, Aperture's interface and philosophy are my favorites. I love the way it handles photo organization. I have one problem, however. Being a relative photographic newbie, I have a terrible time with the adjustments. I seem to have a much easier time making good-looking adjustments in Lightroom. In Aperture, I just aimlessly noodle around, make a mess, and undo all my changes regularly.
I just found the Apple manual on making adjustments. I was wondering what other resources you more experienced photographers used to learn your way around.
Thanks,
Mark

Thanks I have that one on order from Amazon even as we speak. As an update, I've also found some information on bagelturf.com, and it looks as though Aperture Users Professional Network is going to start a 7-part series on Adjustments in Aperture. That sounds just like what the doctor ordered.
O'Reilly's "Inside Aperture" site also seems worthwhile. I'm sure you all know about these. I'm glad they're there. I've subscribed to a couple of podcasts as well.

Good Resource for Finding Java Developer for Startup?

Not sure if this is the appropriate to place to post but we are looking for an interested Java developer to come onboard our very small (2 man) startup to help us with our networked Java application.
I have looked around a little online and not found much so does anybody know where is a good place to scout out such persons? Admittedly we are not flush with $ but we do have some and we would be providing equity along with ongoing cash payment. Of course we also understand we won't be getting the best Java guru out there but then we don't really need that either, just someone capable of simple socket programming, swing and basic SQL stuff. Not rocket science, and we would even consider less experienced developers with a keen interest to learn and use this as an opportunity to develop some new real-world skill so their own. We are very laid back.
Any help appreciated.

I'd try one of:
Your local Entrepreneurs meetup
- there's bound to be one, and people who go along to this sort of thing will either be able to recommend someone or you might even meet the right sort of Java dev there.
The Joel On Software jobs board
- because the right sort of people read Joel On Software
Personal recommendations
- because that's always best; if you're not asking around like crazy, you should be.

Resources for developing a web crawler

Where can I find resources or sample codes on how to develop web crawlers or bots to extract key sentences from online forums? Thanks

You should really learn how to google. You'll never become a good developer unless you know how to search for information.

System copy for ABAP+JAVA system using SAPINST method

Dear support,
We have recently upgraded to ECC 6.0 system and we have been still doing system copy by using backup and restore method. I know its wrong.
which involves below steps , this old methos works fine for ABAP engine and evreything looks ok.But java engine will not work.
So we need to use SAPINST method as described in note 785848 and system copy guide available on OSS. But i am really not able to understand sequence
for tasks to be carried out in this SAPINST method.
Can anybody list few sequence along with step by step procedure as i mentioned below for old system copy procedure.
Is it really difficult to make that for SAPINST as everybody says refer to standard guide and note ?
Anybody if possible can make the same way as i did below , i think it would rather be small as far as my understanding after reading those docs.
Simple old system copy procedure works for ABAP is as:
Run the following command on source system.
a. Login as <sid>adm
b. svrmgrl
c. connect internal
d. alter database backup controlfile to trace;
e. exit;
f. Above command will generate a .trc file in /oracle/P01/saptrance/usertrace directory.
g. Copy the text from CREATE CONTROLFILE until the ( and paste it in to any new .sql or controlfile.sql file.
h. Copy the controlfile.sql to target system.
i. Edit the file and replace the entire source SID to target SID.
j. Edit the reuse database command with the set database command
Copy the aft generated during the backup file from the source system to target system. (/oracle/<SID>/sapbackup)
a. Change all the source <SID> to target <SID>.
b. Only don't change the backup volume name it must be target system <SID>.
c. Copy the above aft file name line from the source back<SID>.log to target<SID>.log file.
5. Shutdown the target server instance.
6. From this onwards all the command on the target system only.
a. Login as <SID>adm
b. run the SAPDBA
c. select J (Restore/Recovery)
d. select B (Full restore and recovery)
e. select A (Select backup of type)
f. Select the offline backup which you want to restore.
g. It will take some time to restore.
h. Once the database is restored login as <SID>adm and run the
i. svrmgrl
j. connect internal;
k. startup nomount (if the database is already mounted shutdown it using the shutdown command)
l. run the following command
m. @controlfile.sql (file name of the control file contains the CREATE CONTROLFILE statement)
n. After the run the above command it should give the "Statement Processed)
o. alter database open resetlogs.
I am really looking forward to see anybody take some time out to prepare this kind of step by step procedure.
It would be of greate help for all of us for performing system copy with sapinst method.
Looking forward for your support.
Best Regards,
AjitR

Hi,
As per the guide you need to do source system Technical Preparations, in that running the export preparation is also one. You need to run this first before you start the export, if and only if export will successful if preparation is successful.
Yes you need to create the export directory to take the export copy of source system, it may be any where in your server. It should be having 6 to 8 GB free space.No need to create the export directory in target system, after export is completed in the source system you copy the export directory to the target system.
Target system
Yes you need to take the back up file system and delete all the contents of the directory.
Yes it can be considered as fresh system installation but copy of source system.
Yes the process follows after you giving the export directory path .
Next screen you will get the database drop and recreate screen chouse the drop and recreate method
Next J2EE user name and password
Next DDIC password
Next you have to give kernel and oracle client dvd path
Next Parameter checking screen here if you are selected database drop and recreate you have to revise the oracle database system option
If you are selecting review next screen is database advance option you have to select the advanced option
Next you have to select following option to recreate
1 Sapdata directory mapping
2 Database instance file system
3 Create database parameter
4 Create tablespace
Next screen sapdata directory creating
Next screen you can just click next no need to change any setting
Next table creation
Next screen specify oracle instance directories
Next again parameter checking and last this is last screen
Next will be the execution screen

Java.util.MissingResourceException: Can't find resource for bundle java.ut

Hi,
I am using a resource bundle and reading a properties file. This is working fine for the existing one. I am getting the exception after I add the new keys in the properties file and run my application.
Can anyone point my error?

AnanSmriti wrote:
Hi,
I appreciate your response. I am using eclipse and I have compiled the classes and copied the properties files and saved in the respective package and finally prepared a jar. Only this added key is not found. The remaining keys are workingThen you haven't done it correctly. If you are actually referencing the correct properties file in the code, and the correct properties file exists in the jarfile, then it will work. If not, not. That's all there is to it.

Need Help For Developing Java Network RPG

Greetings,
Did anyone develop any similar game?I'm developing one for my final year project and i need some guidelines on that.
Thanks for your help in advanced.
Cheers,
yc

Since you are making a 2D game I suppose that speed is not really important. Don't make it too hard on yourself and use objectstreams.
first thing you need is a class which holds all the variables you want to send (like position, health, whatever) and let it implement the "Serializable" interface.
next stop: the client side connection
socket = new Socket(ipaddress, port);
obi = new ObjectInputStream(socket.getInputStream());
obu = new ObjectOutputStream(socket.getOutputStream());and the server side connection:
ServerSocket s = new ServerSocket(port);
while(true) { // keep accepting new connections
socket = s.accept();
obu = new ObjectOutputStream(socket.getOutputStream());
obi = new ObjectInputStream(socket.getInputStream());
}make sure you turn around output and input. The server won't continue unless his output has input on the clientside.
with the objectoutputsstream you can send the objects:
obu.writeObject(netData);
obu.flush();
// make sure you flushreceiving the object:
netData = (YourNetData) oi.readObject();so what you need is a client side function that sends objects, a client side thread that handles received objects.
The easiest way to make a server is making an array of client threads and put the socket and the objectstreams in the thread. The thread can read an incoming object and send it to all clients in the array. This way you never have to change your server, you only have to change the object you send.
