Hello,

Is there any hook to capture OSGI startup issues before starting the Eclipse RCP appilcation, Can we add any hook to inform the user with custom messages.Advance thanks for your support.

For example start up errors:

case 1:
]$ java.lang.IllegalArgumentException: Buffer size <= 0
at java.io.BufferedInputStream.<init>(BufferedInputStream.java:201)
at org.eclipse.osgi.framework.internal.reliablefile.ReliableFile.getInputStream(ReliableFile.java:272)
at org.eclipse.osgi.framework.internal.reliablefile.ReliableFileInputStream.<init>(ReliableFileInputStream.java:92)
at org.eclipse.osgi.framework.internal.reliablefile.ReliableFileInputStream.<init>(ReliableFileInputStream.java:66)
at org.eclipse.osgi.storagemanager.StorageManager.updateTable(StorageManager.java:487)
at org.eclipse.osgi.storagemanager.StorageManager.open(StorageManager.java:708)
at org.eclipse.osgi.storage.Storage.getChildStorageManager(Storage.java:1792)
at org.eclipse.osgi.storage.Storage.getInfoInputStream(Storage.java:1809)

at org.eclipse.osgi.storage.Storage.createStorage(Storage.java:88)
at org.eclipse.osgi.internal.framework.EquinoxContainer.<init>(EquinoxContainer.java:66)

case 2:
java.io.IOException: Unable to initialize osgi.frameworkClassPath

Have you checked error logs? These errors mean something is wrong with starting Eclipse and error logs might help.

Hello Alex Kravets,

Thanks for your reply.

I am talking about capturing those errors from Custom code & inform the user in controlled way.

As we can have hook configurators,those can be contributed through OSGI fragment.
In Similar line can we add any hook to capture those errors from Custom code.

Thanks,
Raghava Rao

You can use org.eclipse.ui.startup extension point to execute your custom code during Eclipse starting phase: https://wiki.eclipse.org/FAQ_Can_I_activate_my_plug-in_when_the_workbench_starts%3F and https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fui%2FIStartup.html talk more about this.

You can also control your startup plugin's loading time by manipulating configuration section of your product - since you said you are working with RCP, it may be product based:

Quote:

<plugin id="com.iwaysoftware.eclipse.startup" autoStart="true" startLevel="5" />
<plugin id="org.eclipse.core.runtime" autoStart="true" startLevel="3" />
<plugin id="org.eclipse.equinox.common" autoStart="true" startLevel="2" />
<plugin id="org.eclipse.equinox.ds" autoStart="true" startLevel="2" />
<plugin id="org.eclipse.equinox.event" autoStart="true" startLevel="2" />
<plugin id="org.eclipse.equinox.p2.reconciler.dropins" autoStart="true" startLevel="4" />
<plugin id="org.eclipse.equinox.simpleconfigurator" autoStart="true" startLevel="1" />
<plugin id="org.eclipse.update.configurator" autoStart="true" startLevel="3" />

Here we are loading our com.iwaysoftware.eclipse.startup last, but the startLevel can be changed to meet your needs.

HTH,
Alex

Hello Alex,

Thanks for your detailed reply.

As Suggested,We have provision to do some process After starting the Workbench with the help of org.eclipse.ui.startup -->earlyStartup().

But We wanted to Customize the messages for exceptions thrown from org.eclipse.osgi.internal.framework.EquinoxContainer. RCP appilcation will not be called by that time.(Workbench will not be created )

We could able to filter some of the bundles with hook configurators,those can be contributed through org.eclipse.osgi fragment.

Similarly Can you please suggest on those lines.

Hope I could able to communicate the requirement.

Thanks,
Raghava Rao
