[JBoss Portal] - Re: SQLGrammarException in JBP 2.4
by roy.russo＠jboss.com
Mysql allow 1024 key lengths, but since were in UTF8 db setting, its using bytes per... so 255*3 + 255*3 > 1024.
One workaround Im looking at, is to modify the hibernate cfg:
| <class
| name="org.jboss.portal.core.impl.model.instance.UserInstance"
| table="JBP_INSTANCE_PER_USER">
| <cache usage="@portal.hibernate.cache.usage@"/>
| <id
| name="key"
| column="PK"
| access="field">
| <generator class="native">
| <param name="sequence">instance_seq</param>
| </generator>
| </id>
| <many-to-one
| name="instance"
| column="INSTANCE_PK"
| class="org.jboss.portal.core.impl.model.instance.InstanceImpl"
| cascade="none"
| fetch="select"/>
| <property
| name="state"
| column="SER_STATE"
| not-null="false"
| unique="false"
| length="50000000"/>
| <properties
| name="user_and_portlet_ref"
| unique="true">
| <property
| name="userId"
| column="USER_ID"
| not-null="true"
| length="170"/>
| <property
| name="portletRef"
| column="PORTLET_REF"
| not-null="true"
| length="170"/>
| </properties>
| </class>
|
This is a shortterm fix, as it requires testing.

[JBoss Getting Started Documentation] - Problem with Duke's bank example at chapter 4.1.7 (startguid
by mfinke
Hi,
as many of us I am also a new to JBoss and started last week with the tutorial including the Duke Bank example. I download and unzip the two zip files in order to run the Duke example. Following the tutorial everything seems fine until I ran the ant -f jboss-build.xml db-create-table and ant -f jboss-build.xml db-insert statements.
The output on my console looks like this:
C:\Temp\Java\tutorial\j2eetutorial14\examples\bank>ant -f jboss-build.xml db-create-table

[Tomcat, HTTPD, Servlets & JSP] - Taking a screen shot when Jboss is running as a windows serv
by kavlondon
When running jboss from the standart bat file my application functions as expected, ie. takes a screen shot of the host mashine and writes it into the browser window, but when I run Jboss as a service:
"JBossService.exe -install JBoss C:\AVPB\jdk1.5.0_04\jre\bin\server\jvm.dll -Xmx400m -Djava.class.path=C:\AVPB\jdk1.5.0_04\lib\tools.jar;C:\AVPB\jboss-4.0.3SP1\bin\run.jar -start org.jboss.Main -stop org.jboss.Main -method systemExit -out C:\AVPB\jboss-4.0.3SP1\stdout.log -err C:\AVPB\jboss-4.0.3SP1\stderr.log -current C:\AVPB\jboss-4.0.3SP1 -auto
sc start Jboss"
It doesn't seem to function correctly, I don't see any errors but it returnes me black screen instead of a screen shot.
System.out.println("Display-"+GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().toString());
the above returns this:
Display-Win32GraphicsDevice[screen=1]
Please somebody Help me ! :-)

I had the same problem. I installed the Alpha1a version into eclipse 3.2. It was my first installation of the IDE and I did not see the option listed. Then I later when back to an older version of the IDE, I think 1.6, installed that and reinstalled the Alpha1a version, now I can see the configurations.
