My Java Dev. System Has No Class

I'm installing j2sdk1.4.2_03 and it's NOT creating a class directory.
Took me a bit of time to figure that out.
Any clues? (This is on a Win XP Home system).

Here is the directory structure that is created by an install of the current SDK on a Windows machine. There is no folder named "classes". (This information is from the Sun installation document, viewable from where you downloaded the SDK
Installed Directory Tree
The Java 2 SDK has the directory structure shown below.

Java.lang.system and InputStream

java.lang.system has 3 fields defined:
static PrintStream err;
static InputStream in;
static PrintStream out;
As InputStream is a abstract class, can it be used to declare a variable? If so, how to instantiate?
Thanks

java.lang.system has 3 fields defined:

As InputStream is a abstract class, can it be used to declare a variable? If so, how to instantiate?You cannot create an object from an abstract class; you can create an object from a sub class of
that abstract class, and that's exactly what that Stystem.in is refering to, an object from a sub
class of the abstract class InputStream. This sub class still IS-A Inputstream and all you have
to know that it behaves exacty as an InputStream.
Think of it this way -- 'birds' by themselves do not exist; sparrows exist and parrots and penguins exist.
Still you can point to a penguin and say "hey! That's a bird". And so is the object refered to by the
System.in variable an InputStream.

CE 7.30, CM Services/CTS+: Error when creating DEV system in STMS

Hi,
first of all: Happy new year
This is our scenario:
CM Services are running under CE 7.30 and CTS+ is running on PI 7.11 system (Support Package 7).
I followed this guide to configure CTS+ on our PI 7.11 system:
[http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b08abb67-0e34-2d10-78b8-e7246ad93fb2|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b08abb67-0e34-2d10-78b8-e7246ad93fb2]
When we create the DEV system in STMS, we tick the checkbox "Development configuration" and give the URL to the SLD of our CE system (http://sapt62.xxx.com:56200/sld/).
But when the changes are distributed (I guess that's the time when the CM development configuration is created in the CE system), we get the following error message:
com.sap.di.cts.config.service.core.exception.DIConfReadNameServerException: "Unable to read name server from landscape directory "http://sapt62.xxx.com:56200/sld" using user "NWDI_CMSADM" [DICONF_READNAMESERVER]: Received response is not a CIM Operation Response! Check "http://sapt62.xxx.com:56200/sld/" is the correct URL for the SLD CIM Object Manager (default is "http://sapt62.xxx.com:56200/sld/cimom") and that user "NWDI_CMSADM" has access to the SLD via http and is not required to change his/her password.
What can be the reason for that?
The password for user NWDI_CMSADM is configured correctly on the CTS+ system.
Could it be that the username/password for NWDI_CMSADM is configured somewhere in SLD?
After the DEV system has been created we click on the "Development Configuration" button in STMS, the browser pops up with the CM Services and the following message:
Missing application ID
Thanks in advance!

I've seen now that a Development configuration has been created in our CE system.
But I cannot open it from STMS on our CTS+ system, because it gives me the "Missing application ID" message in the popping up browser.
Is that normal?
Another thing I've discovered:
When I try to use the "Synchronize service" functionality for my CTS Dev Conf to load the missing SCA files, I always get this message when I click on "next":
Failed to process the request: Request refers to an unknown session
When I use the "Import service" instead, it gives me a NullPointer exception:
java.lang.NullPointerException: while trying to invoke the method java.lang.String.hashCode() of an object loaded from field com.sap.engine.session.AbstractSessionHolder.sessionId of an object loaded from local variable 'this'

Clients in DEV system

Dear experts! We have standard 3-tiers SAP landscape: DEV- QAS - PRD systems in separate servers. My question is about DEV system clients. By now we have 3 clients in DEV system: 100 client (only Customizing, transport allowed, "Golden" client without any data),300 client (Sandbox) and 500 client (ABAP programming, some application data present, transport allowed). Now we're implementing Change Management with SAP Solution Manager. CHaRM supposes only one dev client with "transport allowed". So, we decided that our ABAP-programmers have to develop their programs in 100 client. But they are not very happy to develop programs in the client without any data! I 've read in SAP Help that DEV system has to consist of Golden(Customizing) client, Sandbox and Unit Test. But I can't find out the answer: where ABAP programmers have to work? Please, suggest me the right answer. Thanks.

If this modification is included in a transport request:
In STMS you will need to add the transport to the DEV buffer by opening up the DEV buffer first, then choosing Extras -> Other Requests -> Add (input the transport number that contains the client-specific changes)
Then highlight that transport in the buffer and hit the import button (little truck) and specify the client you need it to go to in the dialog box.
If the request also needs to go to other clients inside the same system, then choose the options "Leave transport in queue for later import" and "import transport request again" and that will prevent you from having to add the request to the buffer again.

Java can't find main class when manifest has certain JARs on it

I recently wrote an Ant script that builds my application and jars it up, creating a manifest in the process. The manifest specifies the main class and a classpath that mentions other jars that exist in the same directory. Everything works as expected and I am able to run the program using "java -jar abc.jar".
However, I recently started using classes in my program that come from a jar that should (according to the company I work for) reside in a central location rather than each application having its own copy. So, I changed my build script to reference those shared jars in a common location. But now when I run "java -jar abc.jar", I get a java.lang.ClassNotFoundException: com.example.Main. If I edit the jar's manifest and manually remove the new jars from the classpath, the ClassNotFoundException error goes away (although obviously that causes other problems.) Is there something about adding those new jars to the manifest classpath that would prevent Java from finding my main class? My manifest looks something like this and the last two jars (the ones with the absolute paths) are the jars that seem to be the root of the problem.
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 1.5.0_04-b05 (Sun Microsystems Inc.)

\java\jms.jar C:\software\tibco\ems\clients\java\tibjms.jarAny ideas?
Brandon

I still don't know why giving the absolute classpath entry like that would cause Java to be unable to find the jar's main class, but I did make an interesting discovery. If I give the absolute path without the drive letter, is able to find the main class again. Something like this won't work...
Class-Path: C:\software\tibco\ems\clients\java\tibjms.jarBut something like this will...
Class-Path: \software\tibco\ems\clients\java\tibjms.jarBut I'd still like to know why Java doesn't accept drive letters when running on a Windows machine. After all, what if my manifest needed to reference a jar that was on a different drive, like a network drive (since this whole problem came up as a result of shared common jars that need to exist outside of the project.)

Is there a java class which i can use to access the system registry Not really no. You should use Google to search for something. You'll need native code and it will only work on Windows.
and make changes to it. for the time being, assume i have admin access to a system.Regardless this does not seem like a very good idea for a Java project at all. Why do you feel you want to do this? If you want to make a Windows registry editor you would be better off doing it C# or something.

I also get the same problem, this is very tedious but if you edit the song somehow and re-save it then it will copy. Not sure what the problem is at all, tried contacting Apple about this to no avail.

I have found a lot of threads here, but no one help me.
The parameter idleStart is configured to false.
I try to keep BUILD_TOOL_JDK_HOME and JDK_HOME_PATHS as default, and try to set to java 6.
The build variant in CMS was configured too.
After the changes i restated the CBS service and try to import again in DEV system. But nothing happens.
If i import just one or all the components, it get a long time and catch the error showed above.
I have restarted the server a lot of time too.
Can someone have any idea how to fiz it?
Best Regards
Marcos Brandão

Hi Marcos,
changing the domain user might have consequences, please take a look at the note:
#896427 - NWDI Admin User/Password update
What I suggest in short is this:
1. restart the server
2. once the server is up and running, re-save the track in question in cms webui
3. restore system state on dev and cons tabs of cms webui
4. trigger first re-import of SCs on dev tab (import SCs one by one, and do not care of broken DCs until everything is imported).
When I mean one by one I mean that you select an SC on developent tab of the cms webui, press Import, wait what happens to it, and if it failed, let me know. If not, then select the next SC for import.
5. wait until it finishes (depending on the size of your development it can be hours, even up to 4 hours).
If you still got long import and broken DCs, then let me know, this case also take a look at the
1. Import logs which is usually at /usr/sap/JTrans/CMS/log/*
Notice, this can be different in your case, check the location of the transport folder under the CMS WebUI (/devinf – Landscape Configurator – Domain Data Tab)
2. the latest defaultTrace you find at
-...\j2ee\cluster\server<n>\log\defaultTrace.<n>.trc
I also send you another guide for Broken DCs, here you go:

How to check wether local system has blocked by firewall from program.

i am a user in my LAN area. i don't have admin rights. in our LAN few system has blocked by firewall others not blocked .
how can i check wether local host is blocked or not by firewall from java network program ?.

You can execute some kind of firewall util (if any) and parse output to receive configuration and check is address blocked or no. But if you have no admin rights - it will not help you.
Actually there is no clear way to detect was packet blocked by FW or just lost somethere.

Error in import-check of ESS SC in dev system CMS

Hi all,
Im facing some error msgs while performing an import-check of the ESS SC in Dev system of cms. i had no probs in importing other scs for sap-jtech, pcui_gp and others. i downladed ESS 600 SP 10 frm servicemktplace. however the file downloads as a .zip file. after placing this zip file in the cms\inbox folder, i was unable to view the sc in cms/check-iin..i tried renaming the file to .sca. i was then able to view the SC in check-in..my qn is what is the right procedure to convert the .zip -->.sca? i did not encounter this issue when downloading the other files like pcui_gp, they saved as .sca files...would really appreciate any inputs on this. Thanks!

Hi Prachi,
Instead of renaming the zip file to sca, try unzipping the file. It might contain the SCA you are looking for.

Configuring Outbound and Inbound SMTP mails with SUN Java messaging system

hi all,
i am new to Solaris i have deployed SUN java comuunication Suite. How do i configure my messaging server to send outgoing mails through existing gateway and recieve inbound mails from the same gateway?
Currently my server is connected to the internet directly i am able to send a mail to an external domain for example gmail. Can anyone help me out in understanding the default functioning of external mail routing and how do i point to a gateway?
Thanks,
Zafrul

How do i configure my messaging server to send outgoing mails through existing gateway and recieve inbound mails from the same gateway?There is two steps to this.
To configure outgoing emails to be relayed through a gateway, you need to modify the <msg_base>/config/imta.cnf MTA configuration file and add "deamon <gateway hostname>" to your tcp_local channel configuration e.g.
! tcp_local
tcp_local smtp mx single_sys remotehost inner switchchannel identnonenumeric subdirs 20 maxjobs 7
pool SMTP_POOL maytlsserver maysaslserver saslswitchchannel tcp_auth missingrecipientpolicy 0
loopcheck daemon mygateway.com
tcp-daemonTo allow the gateway system to send emails to your host unconditionally, modify the <msg_base>/config/mappings MTA configuration fail and add the gateway's IP address to the INTERNAL_IP mapping table e.g. (where the gateway has an IP of 1.2.3.4 and your system has an IP of 192.168.1.20)
INTERNAL_IP
$(192.168.1.20/24) $Y
$(1.2.3.4/32) $Y
127.0.0.1 $Y
* $NOnce you have done this you will need to rebuild the MTA configuration cache and restart the MTA processes.

<msg_base>/sbin/imsimta restart
Currently my server is connected to the internet directly i am able to send a mail to an external domain for example gmail. Can anyone help me out in understanding the default functioning of external mail routing and how do i point to a gateway?For the understanding, you will need to read-up the manuals. Messaging server is a flexible and powerful product for sending/processing emails, but with that flexibility comes complexity. I suggest you start by reading the Messaging Server Administration Guide:

Java stored procedures and referencing classes

We are referencing to some classes/libraries which are not present in the database. In normal java world, you specify the libraries/classes needed to run your piece of code in the CLASSPATH and that forms part of your complete code.
Can java stored procedures in the database refer to libraries or class files it requires on the file system rather than the database? Is it possible to make this happen?
Thanks

pshiva,
Posting the same question to multiple forums usually doesn't increase your chances of getting an answer, and it just frustrates those wishing to answer you with the result being that any future questions you post may have less chance of being answered -- because of your uncourteous, initial behaviour.
I have answered your other thread:
java stored procedures and referencing classes
In my opinion, that forum (the Database JVM forum) is the most appropriate for your question.

How to import corrections in to DEV system ?

Hi All,
I have to apply the corrections for FI module to my DEV system.
FI Consultant has downloaded that SAP NOTE in to DEV system thru SNOTE, and its status = can be implemented.
NOTE = 1015410 has SAR files as attachements and I have downloaded the corrections [SAR files].
The correctin is for = "Additional Field added for withholding tax codes"
It has 3 SAR files which contains some new Screens and Screen Elements introduced in the Program = J_1IEWT_PROVISIONS.
In the Note = 1015410, it is mentioned that " to apply SAR files, refer to Related notes= 480180,13719. "
Note 480180 says that if it is a correction, " you must follow the installation instructions in the long text of the
respective SAP note in order to implement the correction in your system ".
In the NOTE - 13719, it says we need to open the ftp connection to sapservX [userid/pswd=sapservX] and download the data,
cofiles ?
Iam not sure how we can do this.
And i have Uncared the 3 SAR files and i got the following files :
k003805.CVD - cofile
R003805.CVD - datafile
K087494.P7D
R087494.P7D
K906169.Q3A
R906169.Q3A
In the R/3 DEV server, in /usr/sap/trans,i have a old SAR file = TDS_SAPScript_470.SAR. It had 2 files in it =
K209581.P6B - cofile
R209581.P6B - data file
And K209581.P6B is found in /usr/sap/trans/cofiles/
But R209581.P6B is not found.
Does this means that i have to copy the files of the SAR files to /usr/sap/trans/cofiles/ and /usr/sap/trans/data/ ???
Do i have to copy these files to /usr/sap/trans, and then " tp ADDTOBUFFER ","tp Import ".
And if i go to correction instruction in the SAP NOTE, i have a Transport Request = CVDK003805 in it. Now what do i have to
do with that ?
I have access to OS [hp unix] as root user and also i got access SAP in 000 client.
Please guide me how i can apply these corrections.
