If you can guide me ahead or tell me appropriate Jars or Plugin that can be used to connect to RTC server would be very helpful.

The Plain Java Client Libraries file should have the Jar's. E.g. RTC-Client-plainJavaLib-4.0.6.zip looks like follows:
What do you see if you open it? For calling a Plain Java Client Libraries program see http://rsjazz.wordpress.com/2013/03/20/understanding-and-using-the-rtc-java-client-api/ Manish Ranglani selected this answer as the correct answer
Comments Thanks Ralph, Downloaded the correct version. Code: ITeamRepository repo = TeamPlatform.getTeamRepositoryService().getTeamRepository(repoUri); repo.registerLoginHandler(new ILoginHandler2() { @Override
return new UsernameAndPasswordLoginInfo(userId, password); } }); repo.login(myProgressMonitor); repo.logout(); Output: May 5, 2014 3:30:17 PM org.apache.commons.httpclient.HttpMethodDirector isAuthenticationNeeded INFO: Authentication requested but doAuthentication is disabled
I need to login to server and query stream,
Can you please advise?
Please have a look at my blog as suggested above. There is a lot of example code you can use. You can search the blog as well. Start here: http://rsjazz.wordpress.com/2013/02/28/setting-up-rational-team-concert-for-api-development/
Hi Ralph, I follwed the setting-up-RTC link. After the setup when i try to run snippet1 below is the error: Exception in thread "main" java.lang.SecurityException: class "org.eclipse.core.runtime.IExtension"'s signer information does not match signer information of other classes in the same package Is it some jar compatiblity issue? I haven't seen that error. Not sure. How do you call the snippet? Inside Eclipse?
Yes, ran it as a java application. Not sure what it is. One hint, you need a JDK with the Plain Java Client Libraries. You can try it out inside Eclipse and use the JDK shipped with it (calling the main() not using a batch), or point to the JDK that ships with it. Otherwise, I haven't seen this error, so not sure what it could be.
Hi Ralph, This happens when classes belonging to the same package are loaded from different JAR files, and those JAR files have signatures signed with different certificates. I had removed org.eclipse.core.runtime from Manifest.MF. Executing Snippet shows: May 6, 2014 11:57:54 AM com.ibm.team.repository.common.util.ExtensionRegistryReader logError SEVERE: The com.ibm.team.repository.common bundle's plugin.xml file contains a <component> element with the id attribute value com.ibm.team.links that is not unique.

I am unable to see the last two comments in the forum. I have not seen this, and I can't reproduce the issue. Which version are you using?
I would also be concerned about the "CRJAZ0124I Invalid username or password" Security Exception was because of class being referred from multiple jars. So removed org.eclipse.core from MANIFEST.MF as it exists in plain java_jars.

One other answer
If you want to write standalone Java, use the RTC Plain Java API's. Refer RTC Download section and look for Plain java api
If you want to write Participant or advisor you need server side API's. Refer https://jazz.net/library/article/1000 for examples.
Alternatively you can also use OSLC REST API to talk to RTC via any programming language. Refer https://jazz.net/library/article/635
Comments Thanks for the reply Karthik, i have downloaded
cant find jars in them. |

Comments
are u doing this from Eclipse, or the commandline?
there are a lot of jar files involved with the Java api.
the best is to specifiy the -classpath path_to_plainjava_jars/ *
with the trailing slash to denote directory;
if using eclipse, make a user library (in the build path) pointing to that folder.
(add Library)
Thanks for the reply Sam.
I downloaded RTC-Client-plainJavaLib-API-javadoc-4.0 but cant find Jars into it.
Can you please tell me where would i find plainjava_jars?
https://jazz.net/downloads/rational-team-concert/releases/4.0.6?p=allDownloads
, likely you got only the second one, but you need both:
Plain Java Client Libraries
Lara, i have downloaded both.
but cant see jars in any of the folders.
