Can't connect to Java Engine

I cannot log into my j2ee administration tool. I think it has something to do with the ports being incorrect. Orginially the clustermanager port was set for JoinPort=20020, however I changed it to 31077 according to SAP note 542592. The clustermanager is still not starting up when the SAP system and the j2ee engine start up. Does anybody know of a port issue that may be accuring here? Or possibly some other issue? Urgent help is needed, thanks.

The J2EE Engine Cluster Manager is responsible for handling the elements in the cluster. It updates the information about the status of each cluster element and the services running on it.
Features
Cluster Elements
There are two different cluster element types dispatcher and server. These elements can be organized in groups according to their GroupID.
You can use the Cluster Manager to configure the properties of each element in the cluster. For more information, see Configuring Cluster Elements.
Barriers
The startup/shutdown logic of the J2EE Engine service framework is developed in the manner of a full parallelism, which means that the cluster elements starting up and shutting down immediately without waiting for each other. An option is provided to configure the startup/shutdown of the J2EE Engine cluster to be serialized. This means that there is a designed barrier in the Cluster Manager that permits only one cluster element to start up or shut down at a single moment. The barrier is developed to be customizable. It can be configured from one extreme to another, that is, from serialized startup/shutdown to fully parallel functionality.

File adapter can't connect to xi-engine

Hello,
I have a problem running the file copy scenario from tutorial. The file adapter reads the file and removes it from the source directory but the message never receives the mapping engine.
The adapter throws the error message (sorry it's a german installation):
'Fehler beim Übertragen der Message zum Endpunkt https://hpsaps01.inveos.com:8001/sap/xi/engine?type=entry über die Verbindung AFW. Grund: com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.RuntimeException: Error while silently connecting: org.w3c.www.protocol.http.HttpException: java.io.EOFException: Connection closed by remote host.'
Translated to english this would mean: Error by sending message to endpoint over connection AFW.
The status of the ist wait and changed after some time to system error.

Hi Volker,
I think it is a problem with Cache refresh. SO go to SXI_CACHE and try to refresh the mapping.

If the above doesnt work, Just try to restart AFW and AFxxx services (from Visual Admin)
Steps to restart AFW and AFxxx services are:
Start the Visual Admin tool. Connect to your XI J2EE Engine (640).
Go to Server->Services.
Try to restart such services as "SAP XI AF Messaging", "SAP XI AF Core", "SAP XI Adapter: XI", etc.
It hope it helps.

Can't connect shared variable engine

HI All,
LabVIEW 2009 + DSC
We have one test laptop on our local network. Other developers read values of some variables from that laptop. Now we have a new developer and computer. When we try to browse test laptop from network it can be found but we can't see any libraries there. This is done by using distributed system manager. PING is ok, and there is "no" firewall or virusradars. Other developers can connect that laptop well and there is no problems. Does anyone have good advices to solve this issue?
BR, Jim
Solved!

Re-installation solved this.

Do you need a Java Engine to print W-2?

We are in the process of upgrading our system to ERP 2005 ... in testing, the HR department said they can't print W-2 because the Java engine wasn't installed. Can anyone confirm the java engine is a requirment for W2s to be printed in ERP2005?
Thanks in Advance!

Hi Dawn. We tried doing that when we first ran into this problem a few months ago. It does allow us to print the sapscript forms, but we would still have the issue of the sapscript no longer being supported by SAP for ERP2005. So if we were to have problems with our sapscript later on we wouldn't have any help from SAP. Therefore our plan is still to migrate to the PDF forms, since those will have SAP support. We're viewing the workaround as a sort of temporary last resort in case we need it, just to get the W-2s out for this year.

How do I change the instance number 00 that Java Engine trys to connect to?

Hi All,
I hope you may be able to advise me here....
I have a Solution Manager 4 installation that the Java Engine / Server 0 does not start on.

as show in the error info below. All the other connection info is correct.

When I look at other logs in the system this error is repeated in lots of places.
I can also see that the connection details used to be 00 but somwhere along the line it was changed by someone to 01 which is incorrect. I dont why it was changed.
Does anyone know where I tell / configure the Java Engine Server0 that it should try and connect to SAP Instance 01 to get access.
Hope you can help
Thanks
Alex

Its OK, Ive fixed it.
I went into the offline Config tool, selected Global Services, then fine the service:
ume.r3.connection.master.sysnr
com.sap.security.core.ume.service and change the details for otpion:
ume.r3.connection.master.sysnr
All sorted.
Thanks

JAVA ENGINE is not connected to Data Base using JDBC in XI 3.0?

Hi,
I am copying the DATA BASE from a old DATABASE.
Then i got an error like
Error: java.io.FileNotFoundException: JdbcCon.log (Permission denied)
J2EE Database is not available via test
i.e while i try to connect to the Java Visual Administrator by Command Prompt it shows the above error.
Can anyone suggest me to solve this problem.

Hi,
Your Java engine is not up.
Check the log files under work directory.
Paste the log file here std_bootstrap and jvm_bootstrap files.

Can no longer connect to j2ee engine

I recently posted about an XI 3.0 Demo problem that was fixed by changing the icm/host_name_full parameter in the instance profile to a FQDN (thanks again for the help Alwin!). However, without being able to actually determine why, as we didnt change anything else, we lost connection to the j2ee engine, as we cannot connect to the Integration Builder, nor the SLD, etc. Now when we browse to http://server_name:50000/rep/start/index.jsp we get a server not found error and cannot determine what has changed to cause ths problem. Any suggestions?
Thanks, Eric

Eric,
As you are saying you can't access the J2ee engine. Have you tried to access http://servername:50000
Do you get the opening page then. If not, I suppose your j2ee stack isn't started.
Are the necessary parameters for starting it still there in the instance profile:
rdisp/j2ee_start
exe/j2ee
rdisp/j2ee_start_control
If so, restart the system, and search for the logs of the J2ee. There must be a failure in there.
Best regards,
Alwin

Can't we pass java.sql.Connection as parameter toDatum() method

I am in mid of java 1.3 to 1.4 migration, now I am getting the below error.can't we pass java.sql.Connection as a param to toDatum(), but I did the same before for another module and it worked fine, now I am getting the error.
any changes need to be done?
[b]toDatum(oracle.jdbc.driver.OracleConnection,java.lang.String) in oracle.jpub.runtime.MutableArray cannot be applied to (java.sql.Connection,java.lang.String)
return array.toDatum(c, SQL_NAME);
^
1 error
I changed to use
import oracle.sql.ORAData;
import oracle.sql.ORADataFactory;
instead of
import oracle.sql.CustomDatum;
import oracle.sql.CustomDatumFactory;

In general, it's bad practice to be that "open" with regards to parameters to methods, especially when using remote invocations. However, if you really, really, really, really need to - and I doubt you do - you can use Serializable for the type of parameter. But that's still inelegant and, well, raises all sorts of issues, starting with your design...

How i can make my own connection in java source of a jsp page

How i can make my own connection in java source of a jsp page (How to get connection from JNDI datasource address) ?
imagine that i have a rowset in a web page , now i want to do some operation using
plain JDBC , so i will need a connection object.
I tried to get one of my rowsets connection but it return null ?
what is best way to retrive a connection from JNDI datasource that we define for our project?
for example if i have
myRowSet.setDataSourceName("java:comp/env/jdbc/be");
in web page constructor
now i want a pure connection from the same datasource ? JNDI
Thank you

It is not hard to get your own connection from datasource.
in your case you need to do like the the following code.
i provide sample to show you how to catch the exception and create an statement .
Connection con =null;
try{
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/be");
con = ds.getConnection();
java.sql.Statement st =con.createStatement();
}catch(SQLException sqlex){
sqlex.printStackTrace();
sqlex.getNextException().printStackTrace();
catch(NamingException nex){
nex.printStackTrace();

Financial Reports error message Java API can't connect to olap

Hi,
On version 11.1.1.3, after reapplication of 11.1.1.3 because of other problems with shared services, get the following message on the diagnostics for the financial reporting server.
Launch external checker with next command: E:\Hyperion\common\validation\9.5.0.0\launchEssbaseJavaAPI.bat EssbaseJAPIConnect admin ****** hypolap.msj.org http://hypapp2.msj.org:13080/aps/JAPI
Error: Result: -1; Error message: Cannot connect to olap service. Cannot connect to Essbase Server. Error:Essbase Error(1051293): Login fails due to invalid login credentials
Recommended Action: Make sure external checker is working.
Financial reports over the Web can not connect to the essbase server. Financial reports through the studio works fine. Any suggestions how to troubleshoot or resolve the issue with the login credentials for the Java API to essbase?
Anne

Things to check -
1) Does the user you specified in the connection have the role OLAP_USER
2) Does the user you specified in the connection have access to an OLAP schema (analytic workspace or CWM2 ROLAP schema)
3) Have you installed the correct JDBC files from your database instance into the BI Beans JDBC directory

Can I connect to Oracle server7.1 through Java-JDBC using the latest thin drivers???

Hey Gurus,
Please help me .
MY Current requirement is to connect to multiple oracle 7.1( and other variants) servers running on different operating systems, through Java/JDBC.
My FIrst question is, can i connect to older versions of database using latest drivers?
I could connect to the server running on SCO-oracle 7.1 using SQLNet8.1.7 under windows. But the same is not happening when the client is on Linux.But I need to connect from linux
It says ORA-03113 - End of communication channel.
What may be th problem.
If any one could show some pointers where I can get more information about this problem would be helpfull
THanks
Lokesh

I tried the classpath suggestion above (not the one modifying the .xml file) , but it didnt work for me , I am using WLI 10.3.1 and trying to connect DB on 8.1.7 V . I downloaded the classes12.jar and the ojdbc14.jar file from the oracle and placed in lib and the even included the classpath , but i again got the same exception .
All this while i was selecting the option Oracle Driver Thin from the DataBase Driver when creating the connection pool from console . I tried with "BEA Oracle Driver (Type 4)" and it worked for me .. Although the option "BEA Oracle Driver (Type 4)" lists only the DBs from 9.0.1 to 11 G , but in my case using this driver i am able to connect to Oracle DB 8.1.7 . So all you guys if it classpath doesnt fix the issue try out by selecting Driver , "BEA Oracle Driver (Type 4)" .
Manoj , this will fix the Connection pool part of the ques, but for the java part Try to load the Driver class "weblogic.jdbc.oracle.OracleDriver" before connecting to DB with Class.forName.
Thx

How can i do a NW07 double stack system to standalone java engine

Hi all,
i need a hand to this task.
So i have an Abap (BI) + Java (EP) double stack system which connect to an other Abap (BI, this is the backend system). The abap system from the double stack is useless. So i would like to reduce the double stack to the standalone java. Is there anyboday have any experiance to how to do this?
I have tried to export as standalone and double stack too, the source system but at the install only JAVA i have got an error message:
"Importing the Java dump from a double stack system into a Java Only system is not supported."
So my question is , how can i export the java db from the double stack system for the new only java system?
I hope some of them have an idea....
Thank you very much for your help,
Beeekaa

Beeekaa,
You are trying something very interesting. I have never done it myself but I think below steps may work.
Source system: ABAP + Java system.
Export only java using database specific tools u2013 this will export only SDM content.
Take a database backup u2013 Here you will backup all the tablespaces including ABAP tablespaces.
Target system u2013 Java only.
Restore the database. Delete all the tablespaces other than SAPSR3DB.(this is where we have Java content)
Launch SAPINST and try to import java, so that you will get the SDM content and it runs Java migration tool and changes the JAVA ID that we see in configtool to new number.
Again I am just assuming here, I have not tried it.
Thanks,
Venkat.

export DISPLAY=ipaddress:0.0, but no luck.
Can you explain me what could be the reason.

You are probably creating images on the fly.
Due to a bug/annoyance in the JDK, it requires an X-display. This is not related to the Sun ONE Webserver but a general problem.
-Either install an X server, but this might not be possible because of a server security strip.
-install a virtual X xvfb or something alike to emulate this behaviour.
I thought it would be solved in newer JDK's but in which i'm not sure.

Can't connect to more then one server in a java appl.

Hi:
I'm connecting to OCS via java as the administrator without problems. But, even if I close the first connection
I can't open the second one without getting an user unknown error. If I connect only to one or the other everything works.
Here's part of the code:
// Get system properties
Properties props = System.getProperties();
props.setProperty("oracle.mail.sdk.esmail.encryption", "false");
props.setProperty("oracle.mail.sdk.esmail.driver_type", "thin");
props.setProperty("oracle.mail.ldap.connectssl","true");
props.setProperty("oracle.mail.ldap.sslport","636");
props.setProperty("oracle.mail.ldap.admin_dn","cn=xxxx");
props.setProperty("oracle.mail.ldap.admin_password",xxxx);
session = Session.getDefaultInstance(props, new OracleAuthenticator());
// Connect to the mailstore (Oracle)
OracleStore store = (OracleStore)session.getStore("esmail"); // esmail is the Oracle provider name
store.connect(owserver, -1, owuser, null);
store.close();
owserver="anothermachine";
owuser="anotheruser";
store.connect(owserver, -1, owuser, null);
System.exit(0);
Please help.
