Replacement of Session in Java application.

Hi all,
I am from the JSP world. In JSP one can use Session to save data which needs to be stored till the user logs out. If I am writing a standalone application how I could store details such as user ID etc.. till the application dies.
Antony Paul

Actually I want to do nothing. I was thinking of how stand alone application can store the user id of a user so that it can be accessed from all objects in that application. Is this legitimate ?
How does applets and Swing applications work. Such applications definitely need to store user id and other details.

JCO-Java application unable to open a Frontend GUI session

Hello,

I am having a problem opening a GUI session on a client PC through the JCo java call. It works on some PC's when I am logged in, but not on my PC. But other persons who login on my PC do not have a problem with the application opening a GUI session. I am at a loss. I have had a basis consultant look into this and he could not find a reason for the problem. I have submitted a customer message to SAP and am being told to file this issue in the forum, so here it is. If this is the wrong forum, please let me know which forum would be the correct one.


Problem:
For test purposes, I have created a Java application using the SAP standalone SAPJCO3 vers. 3.0.1. The R/3 backend is 4.6C. The SAPGui version is 7.1 patch level 13 installed on a Windows XP Pro client PC. The application is supposed to start a Frontend GUI session as part of the initial process. This is not working on all PCu2019s for all users. The following are scenarios for two different users on two different PCu2019s, logged on and executing the Java application. The parameters for the Java application are: User, Password, and System Id in this order on the command line after the Java applicationu2019s name. The system Id in our example is PRP in uppercase. This problem happens while connecting to any of our R/3 instances.


Testing of the issue:
Scenario 1:
User gmcghie: This user is the primary user of his/her PC. This PC has not had its registry entries cleaned up for a long time. Starting the Java application from the Windows command line with the supplied parameters, the program is executed and makes the initial connection with the R/3 backend. When the R/3 system sends back a request to start the GUI session, the SAP Logon is executed and opens on the PC. Nothing seems to happen after this.

Here is the JCO exception from the log file:
JCoException eDest: (136)com.sap.conn.jco.JCoException: (136) JCO_ERROR_ILLEGAL_STATE: Launching SAP GUI failed, though it was requested (error message: Communication with SAPGUI timed out)


When you right click on the SAP Logon icon that is in the Windows System Tray on the PC you see an entry that shows a session for Client 000. This is the wrong client being called by the application. The client being called is 600 in this particular scenario.


Here is the connection string sent to backend for scenario 1:
TYPE=A DEST=PRP USER="gmcghie" PASSWD=********** CLIENT=600 LANG=E ASHOST=10.212.120.53 SYSNR=00 TRACE=1 PCS=1 USE_SAPGUI=2


Scenario 2:
User mshin: This user is the primary user of his/her PC. This PC has had the OS re-installed on it within the last few years, hence the registry is likely more clean. Starting the Java application from the Windows command line with the supplied parameters, the program is executed and makes the initial connection with the R/3 backend. When the R/3 system sends back a request to start the GUI session, the SAP Logon is executed and opens on the PC. The connection is made to Client 600 and the process ends. The screens that appear above for the other scenario are not present when the connection is successful. The log file is not included for this as it was empty because it succeeded.


Here is the connection string sent to backend for scenario 2:
TYPE=A DEST=PRP USER="mshin" PASSWD=********** CLIENT=600 LANG=E ASHOST=10.212.120.53 SYSNR=00 TRACE=1 PCS=1 USE_SAPGUI=2

I have the same issue on my PC as the first scenario.
The steps I took to try to get this to work are as follows.
1. Un-installed and re-installed the SAPGui, several times with no change.
2. Compared the registry settings of SAPGui between working and non-working PCu2019s. These were essentially the same.
3. Compared the system variables between working and non-working PCu2019s. These were essentially the same.
It should also be noted that if user u2018gmcghieu2019 from scenario #1 logs into another PC, the program executes correctly (for most other PCs but not all). Finally, if user u2018mshinu2019 from scenario #2 (certain other users as well) logs into Windows on the primary PC for user u2018gmcghieu2019 from scenario #1, and user u2018gmcghieu2019 is used to connect to SAP using the Java program, the program executes correctly. It seems that this would indicate some problem with the useru2019s Windows account on certain PCs.
Why is the connection information being dropped? How is the process of opening the SAPGui on the frontend done?
Any help with this issue is greatly appreciated.
Thanks,
Mark Shirkey

Created Customer Message and got answer. There were settings in Windows Registry for starting the SAP Logon Launch Pad which had to have a value of 1.

How to check if a user session is active in Java application server

Hi Experts,
We have a online scenario with a third party system by which a portal user will launch the third party application in a new window from portal. The SSO will work at the third party web application with the dynamic key that is generated by calling a webservice for that user. Now, as the user works on the launched screen, they will have to check whether the user (logged in portal) session is still active. ie., they will be periodically calling a service hosted by SAP java application server to find out whether the corresponding user who launched the session is still logged in or logged out.
So, my question is, how can i find out programatically whether a user/user's session is still logged in/active in SAP Netweaver Java AS? We are in version 7.3.
Kindly help me in this regard.
Regards
Vijay.K

Hi Vijay,
Could you check below links

How to open JSP session from a java application or an applet?

Hi,
My problem is a bit challenging (at least for me) and its not about JSP but it is about a web application..
I couldnt find a better place to post this question I am sorry if this is not the right place to post it..
I need to enable users log into my website by checking username and password and reading and checking the data from a usb device located in client computer.
I can read from the device thorough JNI using the third party DLL file for the device... I have no problem with that..
Since I need to make native calls I am planning to develop a java application so I let the users open the application using web start.. Once my application is running on client side after reading the device and getting login password information (assuming login information correct), How can I open a web session for the that spesific user and a web browser and let the user browse the web site on his/her own session?
I would appreciate any guidance..
Thanks..

add the values in the header using...
response.addHeader("userNmae","XXXX");use it in all ur pages like say..
if(!request.getHeader("userName")!=null && request.getParameter("userName").equlas(""))
String username=request.getParameter("userName");
}

Hi all, i have one problem. I need to pass some
session to a java bean for processing.. Can i know are
there any possible ways of passing? thanks.if i understand you correctly, and you mean passing a session object
to a bean from a jsp page, do this:
have in your bean:
import javax.servlet.http.HttpSession;
private HttpSession session = null;
public void setSession (HttpSession sessionFromJsp) {
session = sessionFromJsp;
in your jsp:
beanname.setSession(session);
the variable named session is available is jsp pages,
it is an instance of the javax.servlet.http.HttpSession class,
and provides access to the client session information.

I need java application to read session and cookie requests

Hi
I have a java application that can the HTML and links etc but is there a way for the application to
a. retrieve cookies when they are given and
b. know when the cookie is requested
c. present the cookie when when they are requested
d. retrieve session variables when they are given and
e. know when the cookie is requested
f. present them when they are requested
Or is there a component out there where i can look at the code if it's complex
stev

Sure, the cookie is in the HTTP headers, so you don't really need anything special to handle cookies.

How to get Formatted Mail Content through Java Application

I am using a mail sending function in my applet code which is listed below:
Main content is fetched from a format tool bar in JSP Page and it is passed as parameter to applet and it is used inside the mail content.
Same content when passed and executed in a JSP page, the formatted content is not lost and it is included in mail content as what it is fetched from Format Tool Bar.

Unicode characters in the mail content are replaced by ?.
In the function listed above I have used the MIME Setting as
Multipart multipart = new MimeMultipart("alternative");
I have tried by using relative MIME format also as
Multipart multipart = new MimeMultipart("relative");
But I am not getting the actual format passed as input to the Java Application in the mail content.
Can anybody let us know how to overcome this problem?
Thanks in advance.

You need to really understand how the different multiparts work instead of just guessing.
But for your application, you don't need a multipart at all. Just use msg.setText(msgText, null, "html");
Although that doesn't explain your problem, it will simplify your program.
How are you determining that the mail received doesn't have the formatting? Are you viewing it in a
mail reader (e.g., Outlook)? Or are you fetching it with JavaMail?
Are you using an Exchange server? Exchange will often reformat your message to what it thinks you meant.

Acessing EJB from standard java applications

Hello,
What is the best way to access Enterprise Java Beans from a standard java Application? Any suggestions, documentation, links, ... are welcome.
To illustrate the problem, take the shopping cart example (http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Session.html). Suppose I now want to create a shopping cart from another swing application started with the 'java' command and not the 'runclient' command. Is this possible? Has it been done before? What is the best thing to do ? Both the J2EE application (like the shopping cart) and the plain java application are already used by customers and cannot be fundamentally changed (the java command cannot be replaced by runclient).
Thank you.

Several options are available.
The easiest is to have the java app call the EJB via RMI/IIOP. You should wrap that process in the "ejb-home factory" and "business delegate" design pattern. I recommend downloading this design pattern book and reading it through.

Error while running Java application using Crystal Reports 2011

Hello,
I would like to ask for your help.
Environment details:
Java based standalone application in Development environment.
Crystal Reports 2011 (no SP applied)
Oracle 11g ( 32 bit client installed)
Win7 64 bit OS.
Workflow:
While running the java application, which will display the reports I am getting the below mentioned error. I guess that is because I am missing the Crystal runtimes (Correct me if I am wrong).
I know that CR2011 do not have any sdks/ jar available for deployment. In this case, which runtimes should I be using? Does installing CR2011 be enough in the development box?
Please provide me the link from which I can download the same.
Let me know if I need to provide more details on this. Any suggestions are most welcome.
Thank You.

make sure J2EE_ADMIN user not locked.
Ans please check password in secure area. check password in secure store should be correct.
may be you can try with restart of SAP and DB.

Could not deserialize session data, java.io.InvalidClassException

Whenever I click on logout link from Liferay(Which deployed as application on Weblogic 10.3),It shows below Exception in the console however i am able to logout sucessfully.
Could not deserialize session data.
java.io.InvalidClassException: org.hibernate.proxy.pojo.javassist.SerializableProxy; local class incompatible: stream classdesc serialVersionUID = 1180036893511205383, local class serialVersionUID = -2265249369383210104 at java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:560)
It seems to be Classpath polluted with different hibernate jars.But still not able to figure it out.Below is the jar files which i have in classpath.
hibernate-annotations.jar
hibernate-commons-annotations.jar
hibernate-core.jar
hibernate3.jar
Application Server: Weblogic 10.3
Any Help would be much appreciated.

Sounds like you have two different versions of a class in the two applications.
If you change a class implementation and recompile - the updated class gets a new UID. Looks like maybe one app has a jar with the older class and the other app has a jar with the new class.

Debug a Web Dynpro Java Application.

Hi All,
I am trying to debug a Web Dynpro for java application, however I am getting this error whenever i try to do
Failed to connect to remote VM. connection refused.
I tried the following options that were suggested in few Threads
1) I have the J2EE server running in Debug mode,
2) I also ensured that there is no one else using the NWDS in debug mode
3) I restarted the NWDS and the portal server several time.
Are there any other suggestions apart from the ones mentioned above?
the following thread talks about locking of port [link|NWDS: Debug: Failed to connect to remote VM. Connection refused.;. I doubt if that could be the issue.
Can someone suggest how to identify the port is locked and how to unlock it?
Thanks

Hi Bharath,
1) Check if you are following the procedure as mentioned at the following link:
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/849170e3-0601-0010-d59e-ddfce735fac5
2) Please do check whether the Server Instance Debug Mode is "ON"
You can check it from NWDS >J2EE Engine View>Server Instance>server0
If its not then you need to change it and any Basis Team can help you.
3) If it is running in the debug mode then please ensure that there is no one else debugging on the same server node. Generally there is only one instance configured for debugging. If someone is using the same server node instance for debugging then you might have to ask for closing that debug session to continue with your debugging.
4) Check whether you are using the correct server for debugging. Most of the we make mistake while configuring the debug server
5) Check this discussion:
NWDS: Debug: Failed to connect to remote VM. Connection refused.
Regards.

Patching/updating Java Applications in the WebLogic environment.

Hi All,
I'd like to get some feedback on our process and hear if there is some better/different
ideas out there on how to handle patching/upgrading java applications in the WebLogic
environment.
Here is our process:
1) We build using ANT our Enterprise application.
2) We deploy our application using InstallAnywhere to drop the structure into
an environment.
If a patch or update is needed, we again build the Patch/Update using ANT, generating
checksums for each file in every ear/war/jar file as well as any supporting files
(.xml, .properties, .sh, etc.) used in the production structure. We then compare
checksums against what is in production and come up with PATCH_(ear/war/jar) files
with only the changed classes and duplicate production structure with the changed
supporting files.
Using ANT scripts and InstallAnywhere, we backup the files to be replaced in production,
overwrite supporting files, extract packages (ear/war/jar), overwrite classes
with new ones, re-package the ear/war/jar files into production environment and
restart the server.
We patch at a class level due to the configuration settings internal to the package
files (ear/war/jar) that we don't want the customer to have to re-configure everytime
we do a partial release.
Right now, the whole process is automated except the creation of the Patch ANT
script that extracts, overwrites updated classes, updates manifests, then re-packages.
Any ideas on improvements or complete re-engineering of our process to help so
we can get closer to 100% automation?
Thanks,
John

The chances of two applications running at exactly the same time are miniscule. If they each have a connection to the database, and are both trying to modify the same table, then chances are one will be slightly after the other its changes would be committed last. In the case where one might delete a row just before another tries to access that row, you're going to have some sort of problem. However, those circumstances are pretty rare, and even so, some small amount of exception handling can deal with them gracefully.
