Hy Guys,
i’m using myeclipse trial version, for evaluating it on J2ee applications debugging purpose.
I’m starting WebSphere 5.0 with myeclipse, (version 2.6.3) during startup i catch this error:
Source not found for ClassLoader.loadLibrary(Class, String, boolean) line: 1751
and this is console message
[Loaded com.ibm.broker.personality.Personality]
looking for library: bipmainw110.dll
[Loaded com.ibm.ws.messaging.JMSProviderUtils]I tried to search this library on IBM site, but i don’t found it.
After some minutes startup going on…but with this problem, startup time is more than 6 minutes.When i start WebSphere without myeclispe startup time is less than 2 minutes.
When i debug WebSphere, startup time is more than 10 minutes..
There is a way to make faster websphere startup?
Thank’s a lot
Andrea,
There is a way to make faster websphere startup?
There may be, but we need to know where the slowdown is. With both Eclipse and WebSphere running, you’re obviously going to use more RAM than with just WebSphere by itself. How much RAM is on your machine? Do you start up WebSphere with any JVM options to set adjust the memory usage, such as -Xms256M -Xmx512M?

Hy Scott,
I’m launching WebSphere with myeclipse default params -Xmx256M.
My notebook is a P3 with 512MB with XP Pro.What i’m asking if someother also met my same problem of missing library and slow startup.
I worked with JBuilder and WebLogic and so i know what debug J2ee application means,but WebSphere is slow also when i startup it normally inside myeclipse.
Could i improve my startup with some java parameters?Could i improve my startup with some java parameters?
I really don’t know. It will certainly require some experimentation and research as I didn’t see anything on any previous posts when I searched. How about it WebSphere users?

MyEclipse SupportI had the similar problem. I think it’s not the memory problems. It just timeout after about 5 min. Here’s the SystemErr.log:

Once you do that, WebSphere should be able to find it.
I am having similar problems as most others here on trying to get WS 5.1 to be launched from within MyEclipse. I have tried MyEclipse 3.8 and 3.8.1 now on three different machines (2 with 512MB RAM and 1 with 1024MB RAM because I thought it might be a RAM issue). I configured the Java library path to include the needed directories (apparently the bipmainw110.dll is part of WebSphereMQ). That fixed the problem with the startup freezing at the missing dll. However, now I am freezing after the console prints “[Loaded com.ibm.ws.webcontainer.httpsession.SessionContext$2]”. At this point, my CPU load drops to 0% and MyEclipse seems to stop doing anything. To get to this point does take a long time (10 minutes+). WebSphere with launch outside of MyEclipse within 2 minutes.
canthes,
Just to be clear, you do have the WebSphere connector in MyEclipse configured to launch with the IBM JDK that came with your websphere installation, correct? It’s in the ‘java’ subdirectory of your WebSphere installation. IBM heavily modifies their JDK’s for WebSphere and it simply won’t run on a Sun or other JDK.
Scott,
Yes, I am using the JDK that installed in the WebSphere directory as the JDK for launching WebSphere.
Chris
I just retested with Websphere 5.1 and didn’t have any problems.
I simply pointed to the WebSphere 5.1 installation, set the hostname to my machines *real* hostname (not localhost), pointed to the server I created (server1), checked the Is 5.1 checkbox, and set the JDK to IBM’s. Once configured it started up without issue. Have you customized your websphere startup in any way? If so, you’ll need to make the same customizations in the connector by modifying the Paths or JDK configuration page.
