Hello,

We tried to call web service in servlet in orchestra Desginer. But We get errors

We are using Axis2 client for calling web service. We create web service stub in servlet file. We added runtime support jar. lib/ext folder.

but when we called web service. Websphere load class from plugins/axis2.jar. It dosent use axis jar from ib/ext.

We user orchestra Designer 7.2
WebShpere 9.0
Axis 1.6.2

Webshpere has old version axis2 for Itself.


Does anyone have some probmles

I believe it is a WAS setting. Search the forum for a possible answer.

HI ,

when you created a client with java, you need to use another lib addtional to axis2 or axis , in this case you need to add the following to your lib in the webServe :

axiom-api

axiom-dom

axiom-impl

in the version that have in your local enviroment.

maybe you have to add neethi too.

Thank you Ivan,

We put axiom jars in lib/ext. Result is same. You mean we put them web shpere plugins directory? But this directory for webshepere. When we put them in our app lib. this We get "java.lang.VerifyError: JVMVRFY013 class loading constraint violated;" error.

Hi Cemil,

for webShepre follows next steps and recomendation, you can fin this in the OD dev_guide :

Performing additional WebSphere configuration
About this task
For WebSphere 7.0 and later, the Axis2 library files provided by Orchestration Designer conflicts
with the Axis2 library files from WebSphere installation. Therefore, you must configure a separate
class loader for Orchestration Designer applications to use Axis2 library effectively.
Perform the following steps for the additional WebSphere configuration:
Procedure
1. Open the WebSphere Administrative Console.
2. On the Environment menu, click Shared libraries and create a shared library.
3. Copy the following entries into the Classpath field:
${WAS_INSTALL_ROOT}/lib/ext/axiom-api-1.2.13.jar
${WAS_INSTALL_ROOT}/lib/ext/axiom-dom-1.2.13.jar
${WAS_INSTALL_ROOT}/lib/ext/axiom-impl-1.2.13.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-adb-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-adb-codegen-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-json-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-kernel-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-saaj-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-transport-http-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/axis2-transport-local-1.6.2.jar
${WAS_INSTALL_ROOT}/lib/ext/neethi-3.0.2.jar
${WAS_INSTALL_ROOT}/lib/ext/woden-api-1.0M9.jar
${WAS_INSTALL_ROOT}/lib/ext/woden-impl-dom-1.0M9.jar
${WAS_INSTALL_ROOT}/lib/ext/woden-tool-1.0M9.jar
${WAS_INSTALL_ROOT}/lib/ext/XmlSchema-1.4.7.jar
${WAS_INSTALL_ROOT}/lib/ext/VPWebServiceClient-<version>.jar
${WAS_INSTALL_ROOT}/lib/ext/VPAppLogClientWS_<version>.jar
You must modify the version for VPWebServiceClient -<version>.jar according to
the file deployed in the lib or ext directory.
4. Click Servers > Server Types > WebSphere application servers to navigate to the server
configuration page.
5. From the server list, select the server that you want to associate with the shared library.
6. Click Java and Process Management in Server Infrastructure section, and click the Class
Loader link.
7. Create a new class loader, and set the class loader order to Classes loaded with local
class loader first (parent last). Click OK.
8. Select the newly create class loader.
9. On the Configuration page, click the Shared library references link.
10. On the Configuration page, ensure that the shared library you created is selected.
11. Click OK to save the configuration.
12. Make sure you verify all the configuration has been saved, and restart the application server.


best regards

hi Ivan,
thank you. Yes. We found the same solution. We have many runtime .jar. So We need to add all run time jars in this shared library. this solution is not very effective for us.

Our architecture like this . we have base speech application. if application need to web service call. app load run time web service client.jar with app classloader. and then run it

firstly we think only add all axis jar in shared library. We dont want to add our runtime web service client jar in shared library.

but it is runtime. Our client's classloader look firstly webshpere osi plugin classloader.

we didnt solve this problem. I am looking about web sphere classloader type. We tought firstly all runtime class in speech app will use axis share libs. But run time classes used webshpere osi plugin classloader.

We will search websphere classloder arc. or we will add all run time jars in shared lib.

thank you for your help.
