Hi,
Our PI is getting data from WebSphere MQ and pushing to SAP. So our sender CC is JMS and receiver is Proxy. Our PI version is 7.31.
Our connectivity between the MQ is success but getting the following error while trying to read the payload.

Hi Amarnath,
Where exactly you are getting this error?
If you are getting at JMS Sender communication channel, try to stop and start the JMS communication channel and see the status, also use XPI Inspector to get the exact error log.
for reference follow below blogs:

Approval task SP09: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'

Hi everyone,
I just installed SP09 and i was testing the solution. And I found a problem with the approvals tasks.
I configured a simple ROLE approval task for validate add event. And when the runtime executes the task, the dispatcher log shows a error:
ERROR: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'
And the notifications configured on approval task does not start either.
The approval goes to the ToDO tab of the approver, but when approved, also the ROLE stays in "Pending" State.
I downgraded the Runtime components to SP08 to test, and the approvals tasks works correctly.
Has anyone passed trough this situation in SP09?
I think there is an issue with the runtime components delivered with this initial package of SP09.
Suggestions?

Hi Kelvin,2016081
The issue is caused by a program error in the Dispatcher component. A fix will be provided in Identity Management SP9 Patch 2 for the Runtime component. I expect the patch will be delivered within a week or two.
For more info about the issue and the patch please refer to SAPNote 2016081.
@Michael Penn - I might be able to assist if you provide the ticket number

Odata JDBC Service: getting NullPointerException: while trying to invoke the method

Hi,
I am testing OData, for that I followed the steps given in this tutorial:
http://scn.sap.com/community/developer-center/mobility-platform/blog/2014/06/10/creating-an-odata-service-based-on-sap-gateway-soap-jdbc-and-jpa-data-sources-ba
It wasn't working as it should, so to understand it better, I created a new project with Stock table only.
Manually entered all it's properties and then deploy it.
Issue1: when I create a JDBC connection to connect with derby database, The driver field has maximum limit and whole driver string is not copied. Attached is the screen shot.
Where as I need to enter: org.apache.derby.jdbc.ClientDriver.
Issue 2: I can't test the connection from here, weather it's working fine or not ?
Issue 3:
When I deploy the project and test the result, I get the Stock Service, But when I try to run this, I get nullpointer exception.
URL: http://localhost:8080/gateway/odata/sap/WSTest1;v=1
Response:
<?xml version="1.0" encoding="utf-8"?>
<service xml:base="http://localhost:8080/gateway/odata/sap/WSTest1;v=1/" xmlns="http://www.w3.org/2007/app" xmlns:atom="http://www.w3.org/2005/Atom">
<workspace>
   <atom:title>Default</atom:title>
   <collection href="StockSet">
   <atom:title>StockSet</atom:title>
   </collection>
</workspace>
</service>
Now I need to run StockSet, so next url to access the stock list,
to get stocks:
http://localhost:8080/gateway/odata/sap/WSTest1;v=1/SAP/StockSet
Now I get the following response:
    <?xml version="1.0" ?>
    <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
    <code>
    </code>
    <message xml:lang="en">java.lang.NullPointerException: while trying to invoke the method java.lang.Object.hashCode() of a null object loaded from local variable 'k'</message>
    </error>
I am not able to figure out, why I am getting this error and how to fix it.
All I want is to create a ODAta on ESPM_STOCK sample table given in example.
Looking forward to hear from you.
Thanks.

Issue1: when I create a JDBC connection to connect with derby database, The driver field has maximum limit and whole driver string is not copied. Attached is the screen shot.
Are you working on SMP3.0 (lower version than SP03)?
If yes, then there is character restriction in SMP3.0 (SP00, SP01), maximum length for a database driver is 25 characters.
e.g. if driver name is oracle.jdbc.driver.OracleDriver but when you enter this, then you will see onlyoracle.jdbc.driver.Oracle
Until unless we pass the correct driver value things will not work. there is a workaround for this. You create a desitnation with restricted character length.
You would be seeing a property file for each created destination underC:\SAP\MobilePlatform3\Server\config_master\service.destinations\destinations
Go there and open the created "OracleDB" and edit the "DriverName" to the full string:oracle.jdbc.driver.OracleDriver
Please go through this blog for more understanding:
http://scn.sap.com/community/developer-center/mobility-platform/blog/2014/01/09/how-to-connect-an-oracle-db-with-integration-gateway-in-smp3
Note: seems this problem has been resolved in SMP3 SP03
Issue 2: I can't test the connection from here, weather it's working fine or not ?
I didnt find a way to test a destination. So you have to be sure about what all values you are entering.
Once you are done with Destination creation, map it to the respective deployed service under "services" tab.
Issue 3: When I deploy the project and test the result, I get the Stock Service, But when I try to run this, I get nullpointer exception
Make sure you have corrected "Database driver" name manually. And then check if you are facing same issue.
Does this URL expect any input parameters?

Error: while trying to invoke the method javax.xml.transform.Transformer.

Hi All,
I am working on Version 12.1.8 Build(20), I have referred SAP notes 1294013 and placed the following files
- serializer.jar
- xalan.jar
- xercesImpl.jar
- xml-apis.jar
- xsltc.jar
in the specified path.
now when i use XSLT transformation block using IllumRowsetTableWithPageBreaks.xsl i am getting an error
[ERROR] [XSL_Transformation_0]XSLTransform error: while trying to invoke the method javax.xml.transform.Transformer.transform(javax.xml.transform.Source, javax.xml.transform.Result) of an object loaded from local variable 'processor'
please guide me.

Hi Alex,
No, the case you have explained is not applicable to me. Sharing the code snippet for your reference. This is the code due to which my XSLT gives an error, if I remove these lines of code then the XSLT works fine.
<xsl:variable name="ENERGY" select="translate(ENERGY,',','')">
     <xsl:choose>
          <xsl:when test="ENERGY= ''">
               <xsl:value-of select="0.00"/>
          </xsl:when>
          <xsl:otherwise>
               <xsl:value-of select="ENERGY"/>
          </xsl:otherwise>
     </xsl:choose>
</xsl:variable>
Also, the same XSLT works absolutely fine in 12.1 but gives error in 14.0 SP05.

Hi,
If you can't see the login screen of the CMC then it's a problem of webapps and not EIM services.
Try cleaning the Tomcat cache for the BOE webapps and let Tomcat re cache it. Often it does the job.
- Stop Tomcat
- Rename the BOE folder to BOE-OLD in C:\Program Files (x86)\SAP BusinessObjects\tomcat\work\Catalina\localhost\
- Start Tomcat
When the Tomcat process in task manager is done working (it can take 10-20 min+) then try again.
When you're done, you can delete the BOE-OLD folder.
Let me know!

To solve this, just clean up your Java environment and align the versions. You can get version information of the Java compiler using javac -version and of the Java runtime using java -version.
That said, this problem is actually not related to servlets. You didn't get a root exception of javax.servlet package. You just got a root exception of java.lang package, which basically makes it a Java SE problem. Questions related to those actually belongs in the 'New to Java' forum.

Flickr Server Error - HTTP Status 500 - how to fix?

Hi,
Just upgraded to Photoshop Elements 11 on a x64 Dell running Win7. When trying to share photos using Flickr (which worked previously), I get the following:
Any idea what I can do to fix this? I've tried resetting accounts in Adobe Partner Services, Clearing Online Service Data, and refreshing the list of services - but makes no difference.

Hi,
Thanks - I've cleared my browser cache, and tried all the other things available here too, a couple of days ago:
http://kb2.adobe.com/cps/403/kb403064.html
When I tried it, it made no difference. Ironically, just using the Flickr service today 'just works'. Server side, as you say, so maybe something got restarted / fixed?
Given the entire forum web site wasn't accessible yesterday (and that appears to run on Tomcat, too) - perhaps the restart of the one is linked with the restart of the other.
Anyhow - problem solved - thanks for your support!

I am working with the Tomcat 5.5 on Eclipse, and is getting the error when my servlet calls the jsp using request dispatcher, the error is:

dispatcher.forward(request, response);
Any clarifications highly appreciated.
When I debug my code, I find that the config is null just before the RequestDispatcher line. What does that mean ?
thanks.

Looks like you have a space in "D ispatcher"?
RequestDispatcher dispatcher = getServletConfig().getServletContext().getRequestD ispatcher("/view.jsp");If that's not the solution than going by your error you need to check your variable because somehow you're pointing to nothing:

Hello Egor,
<ol><li>I see one error that seems to occur often on your server:
ORA-20867: ORA-12705: invalid or unknown NLS parameter value specified
ORA-02063: preceding line from WWW
ORA-06512: at "SYS.DBMS_SESSION", line 153
ORA-06512: at "APEX_040000.WWV_FLOW_LANG", line 387
ORA-06512: at "APEX_040000.WWV_FLOW", line 9328
ORA-06512: at "APEX_040000.F", line 267
ORA-06512: at "APEX_040000.F", line 294
ORA-06512: at line 2Probably you have some unsupported language or characterset configured for your application or APEX instance as default, which is not taken when you login to your application builder.
</li>
<li>What I see from your log as well: You still use APEX Listener version : 1.1.0.60.10.38, I'd recommend to update to the current 1.1.2 release.
</li>
<li>I see some other errors and warnings in your log, e.g.
WARNING|oracle-glassfish3.1|org.apache.catalina.connector.Request|_ThreadID=20;_ThreadName=Thread-1;|PWC4011: Unable to set request character encoding to UTF-8 from context /apex, because request parameters have already been read, or ServletRequest.getReader() has already been calledand
SEVERE|oracle-glassfish3.1|org.apache.tomcat.util.digester.Digester|_ThreadID=10;_ThreadName=Thread-1;|Digester.getParser:
javax.xml.parsers.ParserConfigurationException: The XDK supports only namespace-aware parsers.
[...]The warning can easily be ignored. I'd recommend to disable it to make keep your log file smaller and clear. See the [url http://wiki.glassfish.java.net/Wiki.jsp?page=FaqWebAppUnableToSetRequestCharEncoding]GlassFish FAQ for that warning.
The severe error is more interesting. There seems to be a problem concerning the XML parser, probably due to a library conflict. There was a thread on a similar issue concerning Tomcat ({thread:id=2174509}), but possibly such things can happen on GlassFish as well, especially when you have installed some global libraries. As you can see in the Tomcat-Thread, removing xmlparserv2-11.2.0.jar from +\apex\WEB-INF\lib+ solved the problem there.
</li>
</ol>
I hope these points help you to solve your problem. If not, can you post some additional information about your NLS/LC settings in GlassFish/Java/APEX environments?
