control - Cannot Change Component Property Values -

i have latest version of redhawk , centos, , have run few problems right off bat. couldn't see chalkboard , sandbox, issue resolved commenting out (#) 1 of 2 lines in eclipse.ini file:

-dorg.omg.corba.orbclass=org.jacorb.orb.orb -dorg.omg.corba.orbsingletonclass=org.jacorb.orb.orbsingleton

i found prepare here. noted while there no obvious errors arose, there may unforeseen problems.

the issue have property values of components, frequency or amplitude, cannot altered. can't alter them properties view or sca component editor. tried undoing #, problem persisted. have since looked jacorb solutions since root of chalkboard problem seems stem there.

this lastly in "caused by:" chain in error log:

caused by: java.lang.classnotfoundexception: org.jacorb.orb.orbsingleton @ java.net.urlclassloader$1.run(urlclassloader.java:217) @ java.security.accesscontroller.doprivileged(native method) @ java.net.urlclassloader.findclass(urlclassloader.java:205) @ java.lang.classloader.loadclass(classloader.java:323) @ sun.misc.launcher$appclassloader.loadclass(launcher.java:294) @ java.lang.classloader.loadclass(classloader.java:268) @ java.lang.class.forname0(native method) @ java.lang.class.forname(class.java:270) @ org.omg.corba.orb.create_impl_with_systemclassloader(orb.java:305) ... 91 more

anyone have ideas on how prepare jacorb issue without commenting out or ideas on how can permission alter values? solutions either 1 appreciated.

update: not issue starting java 7u65, 6u85. see orb singleton class loading bug

the problem due ide trying replace corba-related classes found in java bootstrap class path jacorb-supplied ones. java briefly disallowed few updates starting 7u55 , 6u71. jacorb references need modify bootstrap class path in manual, section 27.1: jacorb programming guide

i able work around 1.9.0 ide modifying ide's bootstrap class path include jacorb , jacorb dependency. steps below assume ide in /usr/local/redhawk/eclipse. first, extract jacorb jar plugin:

cd /usr/local/redhawk/eclipse/plugins jar xf org.jacorb_* lib/jacorb.jar

next, note filename slf4j plugin:

ls org.slf4j.api_*

now modify /usr/local/redhawk/eclipse/eclipse.ini 2 jars prepended bootstrap classpath. you'll want utilize absolute path 2 jars. snippet mine below:

... -vmargs -xms40m -xmx512m -xx:maxpermsize=256m -xbootclasspath/p:/usr/local/redhawk/eclipse/plugins/lib/jacorb.jar:/usr/local/redhawk/eclipse/plugins/org.slf4j.api_1.6.4.v20120130-2120.jar ...

if startup console, may see error slf4j, haven't found problematic. if you've done correctly, should see sandbox show in sca explorer view, above target sdr.
