Hello,
I am using the following configuration:
Sun Java SDK 1.4.2, Standard Edition
Red Hat Linux 9 (Shrike)
Eclipse 2.1.2
Sysdeo Tomcat Launcher 2.20
EclipseProfiler 0.5.30
I have a medium sized web application which I am trying to profile. The
web application contains a third party library provided as a JAR file
(no source). The third party library validates a local license file
(license is tied to the machine) using the crypto APIs.
When I start Tomcat using the Sysdeo Tomcat Launcher, the following
command line is used (obtained through right-clicking/Properties on the
Process):
/j2sdk1.4.2/bin/java
-Dcatalina.home=/home/developer/bin/jakarta-tomcat-4.1.29-LE -jdk14
-Djava.endorsed.dirs=/home/developer/bin/jakarta-tomcat-4.1. 29-LE-jdk14/common/endorsed
-Dcatalina.base=/home/developer/bin/jakarta-tomcat-4.1.29-LE -jdk14
-Djava.io.tmpdir=/home/developer/bin/jakarta-tomcat-4.1.29-L E-jdk14/temp
-classpath
/home/developer/bin/jakarta-tomcat-4.1.29-LE-jdk14/bin/boots trap.jar:/j2sdk1.4.2/lib/tools.jar
-Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,suspend=y,address=localhost:90 84
org.apache.catalina.startup.Bootstrap start -config
/home/developer/bin/jakarta-tomcat-4.1.29-LE-jdk14/conf/serv er.xml
In this case, everything works perfectly. I can set debug breakpoints
in Eclipse and so forth...
I used the "Create a Launch configuration" button from
Windows/Preferences/Tomcat/JVM Settings. I then copied as many of the
elements as I could from the Java Application launch configuration that
was created to a newly created Profiler launch configuration (with which
I hope to profile the application).
Here is the command line that is being executed when I run the Profiler
launch configuration using the debugger:
/j2sdk1.4.2/bin/java -Djava.home=/j2sdk1.4.2/jre
-Dcatalina.home=/home/developer/bin/jakarta-tomcat-4.1.29-LE -jdk14
-Djava.endorsed.dirs=/home/developer/bin/jakarta-tomcat-4.1. 29-LE-jdk14/common/endorsed
-Dcatalina.base=/home/developer/bin/jakarta-tomcat-4.1.29-LE -jdk14
-Djava.io.tmpdir=/home/developer/bin/jakarta-tomcat-4.1.29-L E-jdk14/temp
-XrunProfilerDLL:769,0,0 -D__PROFILER_AUTO_START=0
-D__PROFILER_TIMING_METHOD=0
-D__PROFILER_PACKAGE_FILTER=__A__org.apache.catalina.startup .Bootstrap:__M__java.:__M__javax.:__M__sun.:__M__com.sun.:__ M__org.apache.:__M__org.xml.
-D__PROFILER_WAIT_FRONTEND_CONNECT=1 -D__PROFILER_METHOD_KEEP_MODE=0
-D__PROFILER_INSTRUMENT_SYSTEM_CLASSES=0
-Xbootclasspath:/j2sdk1.4.2/jre/lib/rt.jar:/home/developer/b in/eclipse2/plugins/ru.nlmk.eclipse.plugins.profiler/jakarta -regexp.jar:/home/developer/bin/eclipse2/plugins/ru.nlmk.ecl ipse.plugins.profiler/commons-lang.jar:/home/developer/bin/e clipse2/plugins/ru.nlmk.eclipse.plugins.profiler/profiler_tr ace.jar
-classpath
/home/developer/bin/jakarta-tomcat-4.1.29-LE-jdk14/bin/boots trap.jar:/j2sdk1.4.2/lib/tools.jar
-Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,suspend=y,address=localhost:69 04
org.apache.catalina.startup.Bootstrap start -config
/home/developer/bin/jakarta-tomcat-4.1.29-LE-jdk14/conf/serv er.xml
The significant difference between the command lines is the use of
/Xbootclasspath in the latter version.
In the latter case, I am able to start Tomcat and the EclipseProfiler
starts collecting samples, but when I "ant install" my web application,
the application startup fails during the third party license check
with the following exception message:
Algorithm PBEWithMD5AndDES not available
I am certain that this exception occurs in one of the following two
calls that are made from within the third party library...
SecretKeyFactory.getInstance("PBEWithMD5AndDES");
Cipher cipher = Cipher.getInstance("PBEWithMD5AndDES");
....which indicates that Sun's JCE implementation is unavailable for some
reason (which I of course don't understand yet).
Note that this problem also occurs even when I launch the Profiler
configuration in Run mode (instead of Debug mode).
Questions:
1) I'm not familiar with what bootclasspath means to the JVM. Can
someone explain what the difference between classpath and bootclasspath is?
2) How can I determine what the bootclasspath is for a standard JVM
invocation of a Java application? That is, what is the default value of
bootclasspath when it isn't specified?
3) I have never had need to use the crypto APIs myself, so I'm not sure
why the getInstance is failing. If I assume that it is failing because
there is some registration that happens in a static block or through a
property file somewhere, how do I ensure that registration happens in
the case of a profiled application?
4) Has anyone seen this problem before? What was your solution?
The installation of EclipseProfiler made me a little nervous with the
installation of a specific DLL/SO in the JRE bin folder, but it seems to
work fine for the simple Java applications I created to test it.
I was also unable to get JMechanic to launch Tomcat successfully on
Linux; whenever I attempted to launch Tomcat, the console showed
complaints about invalid hprof parameters.
Should I be trying to use Hyades instead? Or should I breakdown and get
my boss to purchase something like Quest's JProbe? Instrumenting
methods in the application with log statements to measure the
performance of various methods is unrealistic; there are over 400
classes in the request handling portion of the application.
Thanks for your time.

I believe you are hitting the following problem
https://bugs.eclipse.org/bugs/show_bug.cgi?id=44406 and
https://bugs.eclipse.org/bugs/show_bug.cgi?id=38370
There are workarounds described and the problem is fixed in the latest
milestone build of Eclipse (M5)
