Web services client portlet

Hi,

I am writing a Salesforce.com web services client portlet; this portlet consumes salesforce web services. They are using AXIS 1.3 so I put this into the /WEB-INF/lib and deployed. The deployment went okay until it loads SOAP binding, it couldn't find concurrent.jar, which is very weird that if this salesforce WS client is a standalone app or normal webapp, it doesn't need concurrent.jar. So I assumed that this concurrent.jar is used by liferay, which is found in /webapp/ROOT/WEB-INF/concurrent.jar, and it is used for something inside the portal.

Now, I moved all these libraries from /webapps/ROOT/WEB-INF/* to c:\tomcat55\shared\lib and ran it again, it ran without any problems!!!

So I guess the problem is that the axis that my WS client portlet loads from /webapps/SalesforceTransformer/WEB-INF/lib/axis.jar cross loads something or requires something inside liferay portal and somehow this changes the classpath or whatsoever, liferay could not find concurrent.jar anymore. Here is my error message if I do NOT move the libraries from ROOT to shared\lib:

In the current test environment, I can afford the change of those libraries but not in production, so any idea that I can get around this problem? Thanks.

We do not recommend moving libs from the portal to the shared locations. You should keep a separate copy of your dependencies within your webapps lib directory.

Thank you Michael, I resolved it by copying the entire list of all *.jar from ROOT/WEB-INF/lib to my own portlet's lib. This makes my simple portlet(orignal size of war is about 4Memoticon 14MB afterwards but at least it works!

thanks again.

Hi Andy,

I'm working in a Salesforce.com project right now and this includes calling its APIs. Can you please give more details about your integration point ? Are you able to share your work with me ?

Thank you

Definitely.

Basically, I used the API to download the data from Salesforce.com and do data cleansing such as checking duplicates and synchronizing data between Salesforce.com and our AS/400. I use Liferay as user interface and middleware. This program works ass the middleman contains both Salesforce.com API and Hibernate for AS/400.

Another project I worked on was to create Salesforce.com Blackberry middleware. I was unable to use Salesforce.com API on Blackberry MDS because it is too complicated on object type. So I developed Salesforce.com web services client and in there, I exposed my web services to blackberry so my web services client to salesforce is also the web services host for blackberry MDS.

For project details, I am not able to tell you here because it involves some operations but for technical details, you are welcome to ask me anything and I will answer you as ooon as possible if I am able to.

Note: I also tried replicating Salesforce.com objects into our in-house database and it worked flawlessly.

regards,

Andy

You don't need to copy the entire dir, just the ones you need.

But when I copied concurrent.jar, it pops up another dependency trace so I rather copied the whole thing, then deleted those optionals like active-mq.jar, portal-ejb.jar and pdfbox because these files are the most largest. Then I deleted others such as POI and anything that I am sure that I don't need.

Thanks for your reply,

Andy

Whatever jars you need from the portal level, just make the names of those jars in liferay-plugin-package.properties file of this portalt. Then make the WAR file, the dependent jars will get injected into this WAR and will be available during the runtime.

Except jars required by your project you only need to add "portal-impl.jar" from portal JARS in liferay-plugin-package.properties file (and other files those may be required are axis.jar, commons-discovery.jar, commons-logging.jar, jaxrpc.jar, wsdl4j.jar, xalan.jar, xercesImpl.jar, xml-apis.jar) save it and run, it should work fine.

You cannot include portal-impl.jar in liferay-plugin-package.properties. Only one copy of that jar is allowed, and that's in the ROOT/WEB-INF/lib directory.

The stack trace at the top is related to a missing concurrent.jar, the wrong liferay-plugin-package.properties file definition, and also I guess that the OP doesn't know how to add a library to his project when he gets the no class def found exception.

Sure, there are a lot of 'hacks' you can do to make the exceptions go away, but that doesn't make them right, supported, or guaranteed to work.

Copying the portal-impl.jar into your project is worse than a hack - the Liferay build scripts specifically block you from doing it, and you're bypassing it.
