weblogic12c - Deploying OSGi bundle on Oracle 12c throws NPE -

-

on weblogic 12.2.1, trying deploy simple osgi bundle war file using admin console throws npe following logs.

caused by: java.lang.nullpointerexception:          @ org.apache.felix.framework.cache.jarrevision.getmainattributes(jarrevision.java:210)          @ org.apache.felix.framework.cache.jarrevision.getmanifestheader(jarrevision.java:104)          @ org.apache.felix.framework.bundleimpl.createrevision(bundleimpl.java:1235)          @ org.apache.felix.framework.bundleimpl.<init>(bundleimpl.java:112)          @ org.apache.felix.framework.felix.installbundle(felix.java:2905)          @ org.apache.felix.framework.bundlecontextimpl.installbundle(bundlecontextimpl.java:165)

as prerequisite created osgi framework (services->osgi frameworks) based on apache felix. bundle api project few interfaces wrapped in war file. structure of war file below:

myapi-project.war    - meta-inf    - web-inf           - classes           - lib           - osgi-lib                - api-project.jar           - weblogic.xml

weblogic.xml contents are:

   <wls:osgi-framework-reference>    <wls:name>cps-osgi</wls:name>    <wls:application-bundle-version>1.0</wls:application-bundle-version>    <wls:application-bundle-symbolic-name>cpsservices.approval</wls:application-    bundle-symbolic-name>    <wls:bundles-directory>osgi-lib</wls:bundles-directory>

api project menifest.mf contents:

  manifest-version: 1.0   implementation-vendor: baml   implementation-title: cps api    implementation-version: 1.0.0   bundle-manifestversion: 2   bundle-symbolicname: cpsservices.api   bundle-name: cpsservices api bundle    bundle-vendor: baml   bundle-version: 1.0.0   export-package: com.bofa.cp.core, com.bofa.cp.services   bundle-activator: com.bofa.cp.core.activator

i have tried adding additional menifest attributes didn't resolve issue. stuck on point last 2 days. appreciated. thanks.

update: here screenshot of jarrevision class in org.apache.felix.org.apache.felix.main.jar v4.4 comes app server oracle 12.2.1 - enter image description here

possible reason felix cant read menifest.mf file reason. confirm understanding, changed bundle symbolic name in file, didn't change exception. guess close ...

resolved issue. guess - typo in manifest.mf file name(created file name menifest.mf). need break :)

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
