In the course of a project there are always files and directories that you don’t want to check in but which Subversion complains it doesn’t know anything about them.  So it makes sense to tell Subversion to ignore them, in other words, keep quiet.

The mechanism for doing this works okay but I wouldn’t say it’s perfect.

This is how I do it one.

1. Go to the directory where want to ignore a file or subdirectory.
2. Issue the command

   svn propedit svn:ignore .

3. Your editor then will be launched and you can enter one line at a time those files and/or subdirectories you want to ignore.

   some_file
   some_directory

4. Commit your changes.

   svn commit -–depth empty

   Two things to notice.

   1. --depth empty argument

      only commit the propedit changes

   2. Committing your changes means everyone will end up ignoring these files and/or directories so make sure you are ignoring the right ones.
5. If you don’t want to commit your changes you can revert them.

   svn revert .

A few days I installed Cygwin on a new laptop.  I saw the warnings that Cygwin 1.7.x is new but I chose to ignore it for now.

I soon noticed that Cygwin was not remembering my mounts.  After reading this on the Cygwin front page I realized I needed to do some more research.

… the mount point storage has been moved out of the registry into files. User mount points are NOT copied into the new user-specific /etc/fstab.d/$USER file. Rather, every user has to call the /bin/copy-user-registry-fstab shell script once after the update.

Next I looked at the /etc/fstab file which pointed me to the Cygwin Mount Table documentation.  Using this documentation I did the following steps so that my mounts are always remembered.

1. Manually mounted the C: drive.

   $ mount c: /c

2. Ran mount to determine what to add to my /etc/fstab.

   $ mount
   C:/cygwin/bin on /usr/bin type ntfs (binary,auto)
   C:/cygwin/lib on /usr/lib type ntfs (binary,auto)
   C:/cygwin on / type ntfs (binary,auto)
   C: on /c type ntfs (binary,user)

3. Based on the output of mount I added this line to my /etc/fstab.

   C: /c ntfs binary,user

4. Closed the Cygwin shell, opened a new one and verified the C: drive was properly mounted.

Sometimes you want to check in your JSP page fragment which page loaded it.  Fortunately this is simple with JSTL.

<c:if test="${fn:indexOf(pageContext.request.requestURI,'foo.jsp') != -1}">
  The request URI ${pageContext.request.requestURI} contains foo.jsp.
</c:if>

Simple but something I always forget how to do.

ATG documents how to enable non-XA resources in JBoss 4.2 for SOLID.  We ended up following the same instructions to work with Oracle.

JBoss Note: JBoss 4.2 by default assumes XA drivers, which some ATG applications use; however, there are no XA drivers for SOLID. To enable multiple non-XA resources in JBoss 4.2, add the property in bold text to the jbossjta-properties.xml file, under the <property depends="arjuna" name="jta"> tag:

<property depends="arjuna" name="jta">
  <property name="com.arjuna.ats.jta.allowMultipleLastResources" value="true"/>

You may still see warnings in your log file, but ATG applications will run correctly. To suppress these warnings, add the following to your jboss-log4j.xml file:

<category name="com.arjuna.atg.jta.logging">
  <priority value="ERROR"/>
</category>

For further reading please see Starting the SOLID SQL Database document in the Running Nucleus-Based Applications section of the ATG Installation and Configuration Guide.

When you are developing at home you will probably need to configure your ATG application to send email via your ISP’s SMTP server.  Here is how I configured ATG to send email via Comcast’s SMTP server.

First you need to update ATG’s configuration to point to the Comcast SMTP server by modifying {ATG}/home/localconfig/atg/dynamo/Configuration.properties.

emailHandlerHost=smtp.comcast.net
emailHandlerPort=587

Typically you don’t need to set the emailHandlerPort, it is by default set to port 25.  But Comcast has recently been switching over to use port 587 because email viruses use port 25 on infected computers.

Next you need to update ATG’s SMTP Email service configuration by modifying {ATG}/home/localconfig/atg/dynamo/service/SMTPEmail.properties.

defaultFrom=betweengo@comcast.net
username=betweengo
password=betweengo

These values used to be optional but now are required because Comcast requires authentication as part of its increased security.
