Hi Dale, sorry to take so long -- I should have recognized this immediately. What
is not always obvious when using the GEP is that there really are two JVM's
running: one for Eclipse and another one for the Geronimo server. And
unfortunately, the JVM arguments you establish for Eclipse do not apply to the
Geronimo server. To adjust the JVM arguments for the Geronimo server do this:
1. In Eclipse make sure the server is stopped
2. Go to the Servers view in Eclipse (i.e., the same view that you use to
start/stop the server), and double-click on the server. This will bring up the
Overview panel for the server, which is essentially the properties editor for the
Geronimo server adapter.
3. Page down and on the right side you'll see the section title "Server VM
Arguments"
4. Page down in that section and append your VM arguments at the end -- don't
delete those that are already there. I used the same ones that Kevan used, but
I'm using Java 1.5 and I see that you're using Java 1.6:
-Xmx512m -XX:MaxPermSize=256m
5. Close the editor and save your changes. Now the server will pick up these new
VM arguments when you restart it and you can deploy/redeploy as many times as you
wish. I did it at least five times in the same Eclipse invocation using the
instructions you provided (i.e., editing the applicationContext.xml) and it
worked fine for me, whereas before I couldn't even deploy it the first time
successfully.
Please try this and let me know what happens. I think you'll have better results
now. Meanwhile, I'm going to open a GEP JIRA to investigate if we can
programmatically determine and set the Geronimo server VM arguments using those
already established for Eclipse since obviously the default values for the server
are not always sufficient. Thanks much.

Hi Dale, just a quick note to tell you that I can now reproduce your
failure. Looking for a resolution, and will let you know what I find
out.....

I had already installed jdk1.6.0_06
I had already installed Geronimo: geronimo-tomcat6-javaee5-2.1.3-bin.zip
I installed a fresh Ganymede: eclipse-jee-ganymede-SR1-win32.zip
Added Geronimo 2.1 plugins from within Eclipse.
Then I deployed a web application. The first time, it deploys fine.
The second time, I get an out of memory, due to heap space.
The web application may be found here:
http://www.manning.com/dbrown/SampleApplication.zip
1) Download the source code from above, and unzip.
2) copy Struts2InAction.war to Struts2InAction.zip
3) Unzip the Struts2InAction.zip file to a folder called WebContent
and delete Struts2InAction.zip
4) Validate that your WebContent has WEB-INF, index.html, etc.
5) In your Eclipse workspace folder, create a folder called
Struts2InAction, and move your WebContent folder into it.
6) Start Eclipse
7) Right-click in Project Explorer, New > Project > Web > Dynamic Web
Project (next)
8) Project name: Struts2InAction > select Geronimo 2.1 > (next)
9) Leave Context Root and Content Directory, but change Java Source
Directory to WebContent/WEB-INF/src > (finish)
10) Right-click your project > Run As > Run On Server
11) Point browser at http://localhost:8080/Struts2InAction
<http://localhost:8080/HelloWorld>
12) index.html will say "one moment please" while the jsp compiles,
then the menu will come-up.
13) Back in Eclipse, edit (for example) WEB-INF/applicationContext.xml
with your MySql login and save the file.
14) Wait for the application to republish itself.
This is where the error occurs:
Deployment failed due to java.lang.OutOfMemoryError: Java heap space
I've started Eclipse with -vmargs -Xmx768M and get the same result.
Not able to put 1024M in there, for some reason (Eclipse won't even
start).
