wsimport OutOfMemoryError Exception

[Murat Demirel]

Hi team,

I am trying to run the sample application as mentioned in the document https://developer.cisco.com/site/collaboration/management/axl/learn/how-to/axl-java-sample-application.gsp.

However, when I type wsimport command, I am getting an "OutOfMemoryError: Java heap space" error even if I use the Xnocompile parameter as follows:

$ wsimport -keep -b schema/current/AXLSOAP.xsd -Xnocompile -s src -d bin -verbose schema/current/AXLAPI.wsdl

parsing WSDL...

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

I tried to increase the heap size but it didn't work. Do you have any idea?

Thanks and regards,

Murat

Hi team,

One more comment. I enabled debug and run the command again. Here is the output:

[DEBUG] Authorization file "/Users/mudemire/.metro/auth" not found. If the WSDL access needs Basic Authentication, please provide authorization file with read access at /Users/mudemire/.metro/auth or use -Xauthfile to give the authorization file and on each line provide authorization information using this format : http[s]://user:password@host:port//<url-path>

Maybe, this can clarify. What kind of authorization do we need?

Thanks and regards,

Murat

If you try to generate the class from local wsdl/xsd. It shouldn't ask for the authorization.

Or, according to the wsimport document, you might want to pass a authorization file as an option

wsimport -Xauthfile <file>

The file should contain an URI as shown below

http://<user name>:<password>@<host name>/<Web service name>?wsdl

JAX-WS RI 2.1.1 -- wsimport

Hi Howard,

Thanks for your reply. Yes, I'm trying with local files. I'm following exactly the document on CDN. Do you have any other ideas?

Then, it's not the auth problem. I see the same error message when I turn the debug mode on.

Mine is set to -xmx512m, maybe you want to try that. Or, you want to post the rest of the error messages?

Thanks,

Howard

Hi,

Thanks to Howard, we confirmed that the issue is heap space, not authorisation. In order to increase the heap space, I tried several options but none of them worked. It seems that setting environment variables on MAC OS X is different than Windows.

After several different attempts, finally I found out that wsimport command accepts java command parameters with -J option. So, I added -J-Xmx512m to the wsimport command and it worked fine. Following is the final version of wsimport command:

wsimport -J-Xmx512m -keep -b schema/current/AXLSOAP.xsd -Xnocompile  -s src -d bin -verbose schema/current/AXLAPI.wsdl

I think the following post should be updated with this information.
