ServiceConstructionException while accessing OKM webservices

[preethism]

Hi,

We have a web application deployed in JBoss 7 and it uses OpenKM 6.2( bundled with Tomcat ) to manage documents.
I have created a client jar (as per the steps in the OpenKM Wiki) and the application accesses the OpenKM web services through this client jar.
While accessing the OKM services, occasionally we get the "ServiceConstructionException" when we access com.openkm.ws.client.document.OKMDocument or com.openkm.ws.client.folder.OKMFolder.

One scenario is to read a document from OpenKM repository:
1)Login to the OKM server by calling the service com.openkm.ws.client.auth.OKMAuth - login(user,pwd)
2)Call the service com.openkm.ws.client.document.OKMDocument - getContent(token, path, checkout) - to read the contents of a given file
3)Logout of the OKM server by calling the service com.openkm.ws.client.auth.OKMAuth - logout(token)

The first step executes fine, but an exception happens on step 2.
The wsdl matches with the classes in the client jar and if we restart the Jboss server the exception doesn't occur for some time.
I couldn't fix on any particular reason when exactly this exception happens, it occurs randomly.

Here is the stack trace of the exception we get:

Can someone shed some light on how to solve this?

[jllort]

Could be some problem with ports ( tomcat and jboss ). To be sure is not it I suggest stop jboss and execute the client ... if all goes fine then the problem is with jbos / tomcat configuration.

The problem is ramdonly for what you told ? with jboss stopped too or not ?

[preethism]

The tomcat and jboss use different ports and the problem occurs when the client accesses the OpenKM through jboss only.
When tried outside Jboss, using Junit tests, the problem doesn't occur.

[jllort]

could be a problem with org.apache compatibility. But not always you get the error or you get always ?

[preethism]

No.The error does not occur always..
Also, the problem doesn't happen when the authentication is done using:
com.openkm.ws.client.auth.OKMAuth - login() and logout()

After logging in successfully through code, when we try to read or write a file, this error occurs sometimes.

[jllort]

Can you share some minimal code to take a look on it ? I would like to see all steps are right.

[preethism]

Here is the code snippet which makes this call:

Code: Select all

public byte[] getDocument(String filePath) {
		byte[] content = null;
		String token = login();
		String path = OKM_ROOT + filePath;
		OKMDocument docService = new OKMDocument_Service().getOKMDocumentPort();
		try {
			logger.info("OKM DOCUMENT : filePath " + filePath);
			content = docService.getContent(token, path, false);
		} catch (com.openkm.ws.client.document.AccessDeniedException_Exception
				| com.openkm.ws.client.document.DatabaseException_Exception | IOException_Exception
				| PathNotFoundException_Exception | com.openkm.ws.client.document.RepositoryException_Exception e) {
			logger.info("Exception in get Document:" + e);
		}
		logout(token);
		return content;
	}

	private String login() {
		String token = null;
		OKMAuth okmAuth = new OKMAuth_Service().getOKMAuthPort();
		try {
			token = okmAuth.login("okmAdmin", "admin");
		} catch (AccessDeniedException_Exception | DatabaseException_Exception | RepositoryException_Exception e) {
			logger.error("method login error" + e);
		}
		return token;
	}

The client jar is included in the WEB-INF/lib of the web application war file.

[jllort]

Seems right. Do you got jbossws.sar deployed ? and do you use jboss webservices ( otherside we could try to remove it ) ?
All seems some library incompatibility or similar and it's not easy find this kind of problems.

[preethism]

Nope. We do not access any web services other than OKM.
So jboss webservices and the jbossws jars are not included as part of the application lib.

[jllort]

I do not know the cause of the problem but for what you explain here seems in some cases the ws method do not exists from your environment and other yes. I suggest you make the question at jboss forum because seems there's some problem there and sure you're not the first who got this kind of problem (probably not with openkm but sure accessing to other ws )

[preethism]

Yeah.. Will try in the JBoss forum too. Thanks for the help, jllort!
