ClassNotFoundException: org.apache.commons.jxpath.JXPathContext while refering IdfWorkitemEx class

Hello All,

I have created job and deployed as module in repository (CS 6.7). Job is working fine, but when it tries to access IdfWorkiemEX classes , it throws following error.

If I place commons-jxpath-1.2.jar serverapps/lib of method server, i do not get this error. But as per Mehod server policy and EMC I do not copy this JAR to ServerAppsEar/lib, if I keep on ServerApps/lib location it throws Lifecycle apply error

Question :

1. No one can use IDFWorkiemEX API in custom job for setting Sructured Data type ?

2. If yes, what is the alternate way to do , apart from copy of jar to ServerApps/lib ? I tried with JAVA LIB in Composer artifacts but still it gives error of java.lang.ClassNotFoundException: org.apache.commons.jxpath.JXPathContext

3. Can some one provide any pointer to resolve referrence of JXPathContext or workaround for DM_POLICY_E_ERROR_1800 for setAtrName ?

Thanks to EMC , finally they identified issue was with , method artifact job method was not selected as workflow method, After selecting checkbox of use as workflow method it started to refer bpm.ear in which requried jar is already placed.

In my project i am using JAVA LIB for external jar that i am using for my module

its working fine for me

i hope you are follow correct steps to define JAVA LIB but still i am sumrize some steps

1.you need to define JAR definition in composer

2.pack that jars definition in JAVA LIB

3.when u difine module that time in deployment tab u need to select that JAVA-LIB

Please let me know if you have any questions on it

Kothari

I already done above steps (considering Composer feature of external jar will work), problem is something related to class loader.. still getting issue. Now I have removed the JAR from ServerApps lib and by adding as exernal jar as per above no working getting class no found (cleared all he cache of content server)

manishanandswami

I hope you did all correct steps ,but normally developers did mistake to when they create JAR DEFINITIONS

Please cross check following steps

1.when you create jar definition that time please make sure you Select correct Type (Implementation,Interface..)

2.Once your jar deployed in to repository then you can cross check with following

DQL select * from dmc_jar where object_name like 'sbo_services' here sbo_services is custom name of your jar artifacts Please check out the content of jar in local temp file and make sure your class or interface is there in jar file for both implementation jar and interface jar

3.because in my project I am using lot of third party jars for my module ..and its working fine there are no issue with composer and DCTM.

4. Hope this trouble shoot will work for you ,if still you are facing same issue then please attach screen shot or some document how you are doing ..so it will give some idea where are you missing some step

Thanks

Swami

-> Already following all the steps of Composer Artifacts. Please find the image for your reference.

-> Query to dmc_jar also giving the expected result.

Now is there any alternate way ?

manishanandswami

can you please check following DQL

select * from dmc_jar where object_name like 'commons_jxpath'

at checkout the content of this jar and check is that correct version or not

also try to open jar def artifact in composer in text editor mode

and check the following entry

<value filePath="content/lib/commons-jxpath-1.2.jar"/>

</contentEntries>

</contentStore>

and check is the jar is correct version or not

its strange ..becuase i am also using same jar files its working fine for me

once u done above stesp ..please install the core dar in to reposiotry

and then stop CS and JMS and delete the cache ..and then test ..

hope this time everything will work

Kothari

Able to get jar content from repository and composer artifact same version.

Still issue persist.

Few question :

1. You are using for Workflow Method module / Custom job method module ?

2. If for Job mehod module can you check , may be accidently you also have jar placed inside ServerApps.ear lib.

Because I sure that for me, not only common jar but bpm_infra.jar both as module JAVA lib not working, I must have to place the jars on method server file system. I.e. jobs executed by ServerApps.ear lib folder.

manishanandswami

Yes in my case its working for both case Module as well as custom job....

but i created module to deploy job...

Please try to use following steps

1.Create the jar files for external third party in your case create jar definition forcommons-jxpath-1.2.jar

2.if its more than then create more jar definitions

3.if there are more jar definitions then you can club all those in JAVA LIB artifacts

4 Now Create a standard module with your custom name ..where you need to define implementation jar and class name

and in deployment tab you can select the JAVA LIB .

5.Create a method for your job in this.. at command you need to define your module which we create in step 4.

6.Now create your job select method which we define in step 5

now install core dar and delete the cache of Content server ...

and it will definitely work ...

Kothari

Exactly doing the same steps, but unfortunately not working.

Kothari

manishanandswami

Cool .... ,this was silly mistake happen some time

Still i am sure about third party jar that we dont need to put those required jar in bpm.ear ..once you defined JAVA LIB artifact and in deployment tab you can select the JAVA LIB in module ..

and at rutime it automatically download that jar in cache folder and it work fine in module .

Thanks

It's not silly mistake Swami. It's abt how you use workflow method checkbox in composer method artifact, if you dont select it will get executed by ServerApps.ear servlet and if you select it will be executed by bpm.ear. Good learning :-)

No one would like to execute job method on bpm.ear (unlesss we use any workflow API) which was in my case.

BTW.. Thanks for your support on this Thread :-)
