Question : SAP xMII 11.5 Servlet Exec Stack / Unresponsive

Hello SAP xMII Master,
I need your suggestion and assist.
Since migrated from Lighthammer Illuminator 10.0 to SAP xMII 11.5, we frequently having problem Servlet Exec stack/unresponsive and looks like hang. If happened, fast solution usually to restart the services of Servlet Exec and situation will back to normal. But, there will happen again and until now we don't know what the root cause.
ServletExec.log is clean for error messages. We already tried increase xml memory up to 1.5 GB. But, there not much help.
Please for any suggestion to resolve those problem.

Hi Mike,

  • IChart Query in SAP xMII

    Hi
    We have an ichart object and the chart type is CUSTOM.
    pen 1 is a bar type and pen 2 is a Line type.
    Questions are:
    1. How can we set the pen 1 be set as a horizontal bar? and still maintain pen 2 as a line?
    2. On the bar shown, how do we display values. I.E. values are displayed on the BARS and not on the X-Axis or Y Axis.
    3. How to make the X-Axis lable Vertical instead of horizontal text?
    We are using SAP xMII version 11.5
    Regards
    Chethan Sreedharan

    Chetan,
    Unfortunately you can not display a horizontal bar in a custom chart. All it allows you is a bar or a stacked bar in addition to Line.
    Rotating labels is part of the 12.1 release and I am not sure on the "display data on the bar" part , may be that is availbale with 12.1 as well.
    There may be other Chart solutions available that might help you. One example being http://www.fusioncharts.com/ Have never used these myself so not sure on the technicalities of this solution.

  • Com.sap.xmii.Illuminator.logging.LHException: java.lang.NoClassDefFoundErro

    Hello,
    Intermittently users get the following error when logging into the application which is built upon xmii:
    com.microsoft.sqlserver.jdbc.SQLServerResource
    At this point in the application it is trying to read information which is stored in a SQLServer database.
    We see the following errors in trace files:
    application [XMII] Processing HTTP request to servlet [Illuminator] finished with error.
    The error is: com.sap.xmii.Illuminator.logging.LHException: com.sap.xmii.Illuminator.logging.LHException: java.lang.NoClassDefFoundError: com.microsoft.sqlserver.jdbc.SQLServerResource
    Exception id: [00145E4D6... [see details]
    This is running on a NW JavaAs 7.0 SP18, MII 12.0 SP8.
    We've replaced the JDBC driver with one which SAP support told us would work, but that did not fix the problem either.
    We can get the problem to go away for a period of time by simply disabling and then re-enabling the Data Server connection.  It is using the IDBC Connector with a SQL connector type.  STATUS shows No. Connections Used 0, No. Connections Available 1, Max No. Connections Used 2.  Max. Wait Time 0.0.
    Ideas?

    Hi John,
    Before connecting SQL server with SAP MII, try connecting SQL server independently.
    It helps to narrow down the problem.
    If the independent connection works fine, try connecting with SAP MII with proper JDBC drivers
    Go through the SAP Note 1109274 & forum MII 12.1 - connection to MS SQL2005 database
    for more information on JDBC drivers.
    Thanks

  • Calling Webservice from Netweaver Portal to SAP XMII 12.0 using SSO

    Hello,
    we have a Netweaver 2004s based Portal and a Netweaver-based SAP XMII (v12.0) System providing Webservices.
    What we try to do is to call a webservice out of the Portal EAR Application using SSO.
    SSO-Konfiguration between Portal and XMII is done and works fine. I tested this using an URL-iView, which calls a https-URL on XMII and SSO-Authentification is done in the background.
    Now I want to call a Webservice using SSO.
    Without SSO (prodiving UID/PW), the webservice-call works fine.
    In order to use SSO with Webservice, I created a "Deployable Webservice Proxy" with "HTTP-Authentication" and "use SAP Logon Ticket" turned on.
    Then I remove Login/Password from my SOAP-Request and unfortunately it doesn't work.
    What do I have to consider in addition to the topics above?
    Can you provide any useful links with tutorials, hints, documentation, ...?
    Thanks in advance
    Andreas

    > Can you please list all the options that we have in order to implement SSO for EP and SAP GUI?
    >
    > I could not find any info in regards to the advantages and disadvantages of each SSO solution. Do you have any links that gives this information?
    If you search the forum here for the terms you have used, then you will find many of them and interesting discussions about advantages and disadvantages from different views. I think that in 1 or 2 hours you will be a guru
    > I am thinking more of using Kerberos authentication for SAP GUI and using OpenSSO (Sun's product)solution for EP 7.0.
    >
    > Do you know what SSO technologies are other companies implementing these days?
    I only know which solutions I have been involved in doing the security evaluations for and implementation support.
    I don't want to do any direct or indirect comparative advertizing here, but only wanted to point out to you that there is plenty of information if you use the search. What you need to understand is that other that SAP proprietary mechanisms and newer standards based initiatives (search for 'SAML'), this is often a 3rd party vendor question (and resulting discussion...).
    If you find a solution and want to specifically discuss it here, then this can most of the time be done in a civilized way...

  • Upgrade JAXP 1.2 to JAXP 1.3 in SAP xMII

    Hi All,
    I need a favour regarding JAXP (Java API for XML Processing).
    I am currently using SAP xMII 11.5 it uses both DOM as well as SAX parser to parse the xml. Also it uses JAXP to talk with DOM and SAX.
    Now the issue is it uses JAXP 1.2 which is not handling big xml. It makes a performance issue when the size of the xml is large.
    So I need to upgrade the JAXP in xMII system.
    Also I am using J2SE 1.4.2.
    So I can’t use JAXP 1.4 or more as it is not compatible with J2SE 1.4.2. JAXP1.4 uses J2SE 5.0 or more.
    I cant upgrade Java version rather I can upgrade from JAXP 1.2 to JAXP 1.3 or some other but lower than JAXP 1.3 & it should be compatible with J2SE 1.4.2 & windows.
    Now the need is to how to implement JAXP 1.3 in an existing system which is already using JAXP 1.2
    Thanks,
    Murugappan.

    Mark:
    Welcome to Apple Discussions.
    You can try using Pacifist to extract Safari from your install disk and install it. You may then be able to upgrade it more easily, although I can't promise that for sure.
    Unless you are absolutely wedded to Safari, I find Camino to be at least as good (I think better) as Safari, and looks almost identical, so that there should not be much of a learning curve. I also use Firefox and especially like it for the measure of security it provides.
    Please do not hesitate to post back with further questions or comments.
    Good luck.

  • Java.lang.StackOverflowError in SAP xMII 11.5

    Hi All,
    I am using SAP xMII 11.5 and Java 1.4. I am trying to display a large iGrid using irpt file. But it is not displaying the grid. I checked log in servletExec folder,it have java.lang.StackOverflowError. How can i solve this issued? Can it be resolved by setting -Xms parameter in Java Run-time environment in server(I am using Windows 2003 Server)? Or should I need to set it in any conf file or pref file inside servletExec folder? Please advice. Thanks in advance.
    Regards,
    Subin

    Hi Thomas,
    MII display applets are nothing else than standard applets. They are executed in the client VM mostly provided by the JavaPlugin in the browser. To give the applets more RAM use the -Xmx parameter and set it in the command line for the JavaPlugin VM. In Windows this can be found in systemcontrol->Java. 64M ist standard. Give it 250M for testing.
    Oh, sorry. Just saw that you found the exception in the server log. Same holds for the server. So try to increase RAM for server VM with -Xmx. Server VM can easily be set to 1GB (but not more than about 1.5G in a 32 bit system).
    Do you have the stack trace for this StackOverflow? Normally this points to endless recursion.
    Good luck,
    Matthias

  • Servlet Exec Thread Monitor - MII 11.5

    We have some reports that get "stuck", and they consume CPU usage, so we have to go into Servlet Exec's Thread Monitor to kill these reports.
    Currently, we go into MII to manually check to see if there are any stuck reports.  It would be nice if we could have MII load these log files automatically and send us an eMail when a report is stuck, so I thought we could use the HTML loader to do this.  The problem is Servlet Exec has security, and it requires an ID and Password.  I thought I could use the HTTP Post action block to get around this, but for the life of me, I can't get it to work.
    Is it possible to use Logic Editor to open Servlet Exec's Thread Monitor screen, and if so, how?

    Hi Lino,
    Keep the original code of the applet.
    <APPLET NAME="myChart" CODEBASE="/Illuminator/Classes" CODE="iChart" ARCHIVE="illum8.zip" WIDTH="840" HEIGHT="400">
    <PARAM NAME="DisplayTemplate" VALUE="Demo_Project/Vale_POC/SampleChart.xml">
    <PARAM NAME="QueryTemplate" VALUE="Demo_Project/Vale_POC/QryValePOC.xml">
    <PARAM Name="TagName.1" VALUE="CylTemp1">
    </APPLET>
    In 11.5 existis guest user. add two parameters in you applet.
    <PARAM NAME="IllumLoginName" VALUE="Guest">
    <PARAM NAME="IllumLoginPassword" VALUE="Guest">
    I believe the best solution would be to use the SAP MII portal for developing your application and not the. NET. In SAP MII already have a lot tools ready for development of application.
    If you use frame follow the link.

  • Problem in retrieving multiple records SAP xMII from SAP using BAPIS

    Hi friends,
             In SAP xMII i called BAPI_USER_GETLIST by passing import parameters 10 and y.In r/3 BAPI returned 10 rows but In xMII it was returned only one Record.
    i want to display 10 records in sap xmii
    1) I created to connection ECC5 in Dataservices-->SAPSERVERConfiguration
    2)In BLS we placed JCO Interface inside Sequence
    3)In BLS I used ECC5 connectrion(using JCO Interface) and called  BAPI_USER_GELLIST
    4)In Links-->Transaction created two input values for "maxnoofrows","withusername" and output value is "userid".
    Input what i mapped 
    Transaction>"maxnoofrows" =====SAPJCOINTERFACE->Request>BAPI_USER_GETLIST>INPUT-->MAX_ROWS
    Transaction>"withusername" =====SAPJCOINTERFACE->Request>BAPI_USER_GETLIST>INPUT-->WITH_USERNAME
    Output what i mapped 
    SAPJCOINTERFACE->Response>BAPI_USER_GETLIST>TABELS>USERLITS >ITEM>USERNAME=====Transaction-->userid
    5)Saved the Transaction.
    6)In Query Template -->xactuateQuery selected
    7)In Datasource Query mode was selected ,Inputrarams i passed 10 and y as parameters.
    It was returned one user id from R/3 inSAP xMII
    please help me to retrive all  10 rows from r/3
    Regards
    Srikanth

    hi,
    What is the data type of Transaction output (userid)?
    Make this as XML type.
    The format which BAPI returns the result does not match with xMII XML format.
    Create a xMII XML document and configure with column name as userid. and by using repeater and XML row add all tho values to the document. Then assign whole doument to transaction output.
    Hope this will help to resolve the issue.

  • How to find Traces in SAP PI 7.3 java only stack

    Hello Experts,
    How to find the trace logs and pipeline steps in sap pi 7.31 java only stack, which we will get in below areas,
    1. In sap pi dual stack , SXMB_MONI (abap stack) in window 1
    2. In sap pi dual stack , monitoring--->integration engine--->message monitoring----> xml messages(data base)
    I  already found some blog related to the logging but i doesn't help to find the traces which we get in SXMB_MONI (window 1, trace)
    http://scn.sap.com/community/pi-and-soa-middleware/blog/2013/09/18/tracing-in-sap-pi-731-single-stack
    Your suggestions are highly appreciated.
    Thanks & Regards,
    Venkat

    Hi,
    In Single stack we go for ICO instead of classical configurations(Pipe line steps(SA,RA,RD,ID)).
    Link you are referring is to find the display of traces that you put in your UDF or Java mapping or XSLT mapping .
    If you want to see the traces/payloads of end to end flow ,then you can see the same either in your communication channel monitoring/receiver channel or via message monitoring/adapter engine-->message log
    If you want to see payloads in the below steps .you can also do so by following the below link.
    Message Staging and Logging Options in Advanced Adapter Engine of PI 7.3x

  • Career Prospects in SAP xMII

    Hi All,
    I want few suggestions from you guys. I am basically a Java Professional. I have 2 years experience in Java, and now, I have been working in SAP xMII for only 1 n half months. I find xMII very interesting. Can anybody please tell me about the career prospects in xMII? I am thinking of proceeding in this line. Do you people find this as a sensible decision? If yes, then how should I proceed? Any kind of suggestion or information regarding this is most welcome.
    Thanks in Advance,
    Lipsa.

    I agree with Ryan - I see lots of demand for xMII skills, and the product is pushed considerably by SAP - I see a reference to xMII in every second SAP PowerPoint presentation (ok, maybe that's a slight exaggeration...)
    I also think that some knowledge/proficiency in the technologies surrounding xMII will be very useful. Some examples of this in the SAP space could include XI/PI, Enterprise Portal, ERP, CAF, Visual Composer, etc. Some understanding of MES concepts and products would also be useful.
    In my opinion, a broad knowledge of the above would help since xMII is an integration product and thus has touch points to a variety of other (non-SAP) systems...
    But I guess a lot depends on how xMII is implemented...

  • Problem in integrating Dreamweaver MX with  SAP xMII

    hi all,
    i am using Dreamweaver MX and xMII 11.5
    i have followed the steps for  <a href="http://help.sap.com/saphelp_xmii115/helpdata/en/Getting_Started/InstallationGuide.htm#Installing_the_Dreamweaver_Add_in">Installing the Dreamweaver Add-in</a>
    <b>i am unable to find the path "http://<servername>/Lighthammer/WizardInstall/IlluminatorWizard.exe" in the server</b>

    Regards,
    Art Team

    Hello Art Tech
    You may need to register the DWWizardGUI.dll.  Here is a snippet from the help documentation:
    If selecting SAP xMII Object does not display the plug-in, open a command prompt and type "cd\Lighthammer\Illuminator\Wizards" to navigate to the folder where the DLLs are located. Then type "regsvr32 IllumDWWizardGUI.dll" which should register the dll. Dreamweaver should then prompt you for the SAP xMII server name or internet protocol (IP) address (it defaults to localhost) when calling up the plug-in; this is similar to the standalone version of the plug-in.
    I may be wrong, but as I recall, you don't have to be in any particular mode to use the plugin in Dreamweaver as you do in Frontpage.
    Kind Regards,
    Diana Hoppe

  • Error while using SAP-XMII 12.1.5 in WINDOWS 7

    Hi All,
    Iam using SAP-XMII 12.1.5 in Windows7 OS.
    Some times I face NULLPOINTER Error in javascript.It was automatically cleared when i restart the system.
    Due to this my MII screens are not working properly.Can any one tell how to clear this Error.

    This error arises in Javascript if any of your variable is not assigned and if we try to access/compare that variable with something.
    If you can share the portion of javascript or the line number which you can see in Window 7 on double clicking at the botton left hand side error icon when u run the application.Than I can tell you the exact solution for it.
    Note : You just need to initial the javascript variable before using it.

  • How to caluculate standarard deviation in SAP xMII

    Hi friends,

    Thats right. there is an Action Block called <b>Simple Statistics</b>, whose function is much different from that of <b>Aggregate Statistics</b> in the usage of BLS.
    <b>Aggregate Statistics</b>
    This is used to return Statistical Calculation Values for a set of Values at one time. This is used with XPath Target (Value Source) hitting a Column in an XML Result. In turn, this gives the Statistical Calculation for the set of values in that column.
    <b>Simple Statistics</b>
    This is used to return Statistical Calculation Values for a dataset which dynamically gets updated with newly added value. So this Action Block is used inside a Repeater Action block, which in turn gets the value from an XML Source, sets that value with ValueSource Property in Simple Statistics. Hence, the calculated statistical value will be dynamically updated with newly added value while looping the XML Source.

  • SAP xMII on a Mac?

    I have been able to access SAP xMII pages and development tools on a Mac using Firefox and Safari browsers. And I was able to do some Business Logic Development on a Mac using the Mac OS.
    Has anyone ever tried installing SAP xMII on the Mac OS? What web server did you use?  Were there any special settings or tweaks that needed to be done?
    The curiosity started a couple weeks ago for me while I was at an emerging tech conference in Philly.  There, to my surprise, the majority of presenters and attendees were using Macs.  I've been on a PC for a number of years, mostly becase of the software that I was using required it (Baan ERP and SAP xMII).

    You could try Apache Web Server and Tomcat.  I've had them working on multiple platforms, but not the Mac - though it should work fine.  The key to making it all work is getting your webapps configured properly and then tweaking the cmsconfig file, located at Lighthammer\WEB-INF\classes.
