Xellerate Adapter Compilation : IOException
Hi
When I try to build an adapter using the thick client, an IOException is encountered. I am using OIM 9.0.1 with JBoss 4.0.2
Any input would be appreciated.
Thanks in advance.
The logs are as follows

Thanks Rajiv. I, in fact, did same for resolution as there was a reference to a directory in logs under /tmp but I wasn't able to find it. Cleaning up /tmp did the trick.

OIM 11.1.1.3 Adapter compilation problem, missing classpath entries
Hi all,
I have installed MSAD connector 9.1.1.7.0 to my OIM 11.1.1.3 box. All the check-marks on the installation page were green.
But in the logs I see no adapters were successfully compiled:

As you may see, neither import com.thortech.xl.dataobj nor import com.thortech.xl.remotemanager are defined in classpath.
Does anybody know where could I configure the adapter compilation classpath?adding the following line to the server launch script did the trick:
export CLASSPATH=$CLASSPATH:$OIM_ORACLE_HOME/server/lib/xlDataObjects.jar:$OIM_ORACLE_HOME/server/lib/xlRemoteManager.jar -
Hi Experts,
I am trying to create a simple adapter with only one 'SET VARIABLE' task which is returning a literal '0'. But I am getting compilation error.

I checked few forums for this and have set XL.CompilerPath to jdk/bin. Also, JAVA_HOME has been set to jdk6 (not bin).
Please provide some pointers for resolution.
Thanks,
RahulThanks Rajiv. I, in fact, did same for resolution as there was a reference to a directory in logs under /tmp but I wasn't able to find it. Cleaning up /tmp did the trick.

Java Adapter Compile Error - Missing Libraries
I am trying to convert my project from being deployed on Flex Data Services 2 To LiveCycle Data Services. I dont know very much about java and have hit a snag when trying to recompile my custom java adaptor.
It compiles fine under a FDS2 project, but when compiled under a LCDS deployment on JRun, Eclipse gives me the following error when trying to compile:
Project PTSChat_Java is missing required library: lib/commons-codec.jar
Project PTSChat_Java is missing required library: lib/commons-httpclient.jar
The project cannot be built until build path errors are resolved
It appears that the libraries have been renamed to commons-codec-1.3.jar & commons-httpclient-3.0.1.jar in LCDS, but I am not sure where to update these references? They are not direct library imports in my java code.
As a shot in the dark, I tried just copying the old FDS2 libraries back over to the WEB-INF\lib\ DIR since there are named differently. It resolved the missing library error, but then I got a compile error with service cannot be resolved in references to my MessageService msgService = (MessageService) service; java code. I quickly realized this is not the correct path to head down.
Does anyone have any clues what I may be doing wrong? Any help is much appreciated.
Thanks!I resovled the problems I was having.
I was able to figure out how to change the library linking in eclipse and switched the commons-codec-1.3.jar & commons-httpclient-3.0.1.jar in the place of commons-codec.jar & commons-httpclient.jar libraries previously used with the project (properties:libraries).
I was not able to correct the service cannot be resolved. Everything I did kept crashing and dropping my connection tot he channel. I ended up just switching the code in my java adapter from:
MessageService msgService = (MessageService) service
to
MessageBroker broker = MessageBroker.getMessageBroker(null);
MessageService msgService = (MessageService) broker.getService("message-service");
This appears to be working as desired for my use of the java adapter for the session management & logging. I am not really certain why the "service" became undefined between FDS2 & LCDS, something must have been depreciated or changed around. -
ORM OIM Integration, adapter compile error.
Hi there,
I tried to set up ORM OIM integration. After importing ormoimBase.xml, I noticed the 'CODE GEN ERROR. See notes.' in the Compile Status for the two adpaters imported (orm_create_update_123 and orm_adpt_delete_123).
Anyone had the same issue? suggestions?
Thanks.I have the same issue in OIM-ORM integration error and the strange thing is that user details from OIM to ORM are reflecting fine but when i make any change in User detail in ORM it is not reflecting...is this the way integration works or i have some error in configuration?

Hi,
We are facing issue during compile of adeptor which is dependent on jar file(suppose A.jar) in javatasks folder.
There is one more adaptor which is dependent on this same A.jar file which is compiling fine,it means there is no issue with A.jar file.
please tell me what other issue could be possible forcompilation error if jar file is working fine.

then it shows complete java file(xellerate/adeptors folder) which generally get create when we compile any adaptor.
for e.g if adaptor name is "tree" then it will create adptree.java file in adaptor folder.
please help me out to get me out of it.
Regrads
Vinayak GargHi,
it is not mandatory both adapter compiled because you are using different method in adapter.
As per your log you are connecting to database in that method that creates problem.

Is java a compiled language - part 2
yamm_v6.6_6 said
Again, I think you are confusing the compilation process and the interpretation process with the meaning of "compiled language" and "interpreted language", mr. jschell. Compilation process and interpretation process have definitions very well established in the Computer Science, as you said, and I agree with you. There are no controversies in those definitions. On the other hand, the meaning of "compiled language" and "interpreted language" might vary, because in this case there are controversiesNo.
Compilers are one of the most well studied and well defined aspects of computer science more so than any other part of computer science.
And the Dragon book is now, and has been for at least 20 years, the recognized authoratative source of that part of computer science.
And there is nothing in there that supports your conclusion nor nothing that supports your term definitions.
A language in of itself is never compiled nor interpreted. That book specifically defines the process under which a language must be processed to become either compiled and/or interpreted.
If you wish to disagree with that then state something from that book or first demonstrate that that book is no longer the authorative source.
Finally note that in terms of computer science none of the java documents (specifications or otherwise) are suitable authoratative sources. The java specifications although adequate are far from precise in the adherence to definitions in computer science, or even in the definition of java itself.Wow! I was just googling, and then look at what I found! This thread! Thanks, mr jschell, for your replies. I really appreciate them.

How about this:
[_CLDC HotSpot Implementation Architecture Guide Chapter 10_|http://java.sun.com/javame/reference/docs/cldc-hi-2.0-web/doc[_CLDC HotSpot Implementation Architecture Guide Chapter 10_|http://java.sun.com/javame/reference/docs/cldc-hi-2.0-web/doc/architecture/html/VFP.html]
+The 1.1.3 release of CLDC HotSpot Implementation included limited VFP support. This feature was supported only when running in interpreted mode. In this release, full vector floating point support is provided when the virtual machine is running in compiled mode.+
[_Java Virtual Machines_|http://java.sun.com/j2se/1.4.2/docs/guide/vm/index.html]
+Adaptive compiler - Applications are launched using a standard interpreter, but the code is then analyzed as it runs to detect performance bottlenecks, or "hot spots". The Java HotSpot VMs compile those performance-critical portions of the code for a boost in performance, while avoiding unnecessary compilation of seldom-used code (most of the program). The Java HotSpot VMs also usesthe adaptive compiler to decide, on the fly, how best to optimize compiled code with techniques such as in-lining. The runtime analysis performed by the compiler allows it to eliminate guesswork in determining which optimizations will yield the largest performance benefit.+
[_CLDC HotSpot Implementation Architecture Guide Chapter 4_|http://java.sun.com/javame/reference/docs/cldc-hi-2.0-web/doc/architecture/html/DynamicCompiler.html]
+Two different compilers are contained in the CLDC HotSpot Implementation virtual machine: an adaptive, just-in-time (JIT) compiler and an ahead-of-time compiler. The JIT compiler is an adaptive compiler, because it uses data gathered at runtime to decide which methods to compile. Only the methods that execute most frequently are compiled. The other methods are interpreted by the virtual machine.+
[_Java Tuning White Paper_|http://java.sun.com/performance/reference/whitepapers/tuning.html]
+One of the reasons that it's challenging to measure Java performance is that it changes over time. At startup, the JVM typically spends some time "warming up". Depending on the JVM implementation, it may spend some time in interpreted mode while it is profiled to find the 'hot' methods. When a method gets sufficiently hot, it may be compiled and optimized into native code.+
[_Frequently Asked Questions About the Java HotSpot VM_|http://java.sun.com/docs/hotspot/HotSpotFAQ.html]
+Remember how HotSpot works. It starts by running your program with an interpreter. When it discovers that some method is "hot" -- that is, executed a lot, either because it is called a lot or because it contains loops that loop a lot -- it sends that method off to be compiled. After that one of two things will happen, either the next time the method is called the compiled version will be invoked (instead of the interpreted version) or the currently long running loop will be replaced, while still running, with the compiled method. The latter is known as "on stack replacement", or OSR.+

AD Connector Error on Weblogic Cluster
hia all,
I have clustered deployment of oim 11g(11.1.1.5) in four node weblogic cluster 10.3.5
While installing ADConnector 9.1.1.7.0 (copied on all 4 nodes at same location) we got following error
DOBJ.EVT_INTERNAL_ERROR
Adapter Compilation Failure Bulk Exception
and in description it says (for the third task)
X Compilation of Adapter Definitions >(Failed)
Is there any way to have it fixed? do we need to set the XL.compilerPath uptill the the \bin of the jrockit? (it is not getting unset / blank once its set, compulsory value). I have also set the limits.config settings in linux to max, since I get "Too many files open" error in the OIM diagnostic log. following is the log

any comments?Ok ... i have resolved the issue, the problem was traced back to the change of access permissions in the Linux. the weblogic "nodemanager" was being started as root user this was changing the permissions on the folders and files in the /home/oracle. so I changed the startup of nodemanager from root to oracle and with some other changes the objective was achieved..... :)

Is Java a compiled language?
Actually, Java is a compiled/interpreted language. See the links below. This is the best classification for the Java language, in my opinion.

[_CLDC HotSpot Implementation Architecture Guide Chapter 4_|http://java.sun.com/javame/reference/docs/cldc-hi-2.0-web/doc/architecture/html/DynamicCompiler.html]
+Two different compilers are contained in the CLDC HotSpot Implementation virtual machine: an adaptive, just-in-time (JIT) compiler and an ahead-of-time compiler. The JIT compiler is an adaptive compiler, because it uses data gathered at runtime to decide which methods to compile. Only the methods that execute most frequently are compiled. The other methods are interpreted by the virtual machine.+
[_Java Tuning White Paper_|http://java.sun.com/performance/reference/whitepapers/tuning.html]
+One of the reasons that it's challenging to measure Java performance is that it changes over time. At startup, the JVM typically spends some time "warming up". Depending on the JVM implementation, it may spend some time in interpreted mode while it is profiled to find the 'hot' methods. When a method gets sufficiently hot, it may be compiled and optimized into native code.+
[_Frequently Asked Questions About the Java HotSpot VM_|http://java.sun.com/docs/hotspot/HotSpotFAQ.html]
+Remember how HotSpot works. It starts by running your program with an interpreter. When it discovers that some method is "hot" -- that is, executed a lot, either because it is called a lot or because it contains loops that loop a lot -- it sends that method off to be compiled. After that one of two things will happen, either the next time the method is called the compiled version will be invoked (instead of the interpreted version) or the currently long running loop will be replaced, while still running, with the compiled method. The latter is known as "on stack replacement", or OSR.+

Problems while compiling a project that uses Database Adapter
Hi,
I am working on a small WebService that uses the Database Adapter to connect with the Oracle-Lite database. The process is a synchronous process which has client and DatabaseService as the partner link. The goal of this project is to get two inputs from the user and send it over to the DatabaseService for it to select the rows from the table based on the inputs sent. The process activity has an invoke function which had two varibles Invoke_1_inputVarible and Invoke_1_outputVarible. I have included the *.xds that contains the database schema. When I compile the project i get the following error
Error(38): [Error ORABPEL-10035]: wrong messageType [Description]: in line 38 of "D:\OraBPELPM_2\integration\jdev\jdev\mywork\Workspace1\Login\Login.bpel", messageType "{http://xmlns.oracle.com/pcbpel/adapter/db/ds/}EmployeeRole_msg" of variable "Invoke_1_dsSelect_InputVariable" does not match the expected messageType "{http://xmlns.oracle.com/pcbpel/adapter/db/ds/}dsSelect_inparameters" in <invoke>. [Potential fix]: make sure the correct variable is used in invoke.
My question is how do I assign correct messageType for the variables.

Hi,
I met the error that Weblogic can compile the jsp to a temporary java file but can
not compile the temporary java file to class file, it said java.io.IOException, anybody
can tell why?
Thanks a millon!
Your system does not have enough swap space to run the JSP compiler.
Add swap space.

SOAP Adapter: java.io.IOException: unable to create a socket
Hi,
I am trying to use the soap adapter to connect to a URL and post a document. When I try, the adapter throws the following
java.io.IOException: unable to create a socket
Does anyone know what causes this?
I get it both with the SOAP Envelope turned on and off.
I am trying to post to a URL that is usually used for straight HTTPS posts, could this cause an issue? The only reason we are using the SOAP adapter is to be able to send attachments! Hence, SOAP adapter, no SOAP envelope.
Kind Regard,
ChrisHi,
Had faced the same issue. The possible reasons were :
1. Either the target server might not be responding.
2. The Target URL configured in the communication channel might be wrong.
3. The port to which the message is being sent might not be opened which you need to cross-verify.
For me the issue was the port, which wasn't enabled from our end. The messages went past successfully once it was enabled.
Cheers!!
